---------------------------------------------------------------------- Date: Thu, 2 Jul 1998 19:35:45 -0400 From: Jeff Renner <nerenner at umich.edu> Subject: Classic American Pilsner update In private email, Jim English <jimebob at mindspring.com> asked for > some tips >for a brew worthy of the impending holiday >based on a Classic American Pilsner. Unless I'm mistaken >you have commented on this particular style >and I would love to ask you a couple of >questions. What a great way to observe the holiday. It's probably too late for HBD readers to brew this quintissential American beer on the quintissential American holicay unless you have yeast ready, but how about next week? You could say I've commented on the style. Beat the drum incessantly, perhaps, starting with a post to HBD that led to my 1995 article in Brewing Techniques, "Reviving the Classic American Pilsner - A Shamefully Neglected Style" - see http://brewingtechniques.com/library/backissues/issue3.5/renner.html This article was a non-technical one intended to rally homebrewers to this style, and it did. It inspired several hardworking brewers to successfully lobby the AHA to get the style recognized. I was originally inspired by two previous articles: "The Bushwick Pilsners: A Look at Hoppier Days," by Ben Jankowski http://brewingtechniques.com/library/backissues/issue2.1/jankowski.html and "Explorations in Pre-Prohibition American Lagers" By George J. Fix http://brewingtechniques.com/library/backissues/issue2.3/fix.html. There was also a big subsequent cover article in Zymurgy sometime in 1997 on pre-pro lagers, which is not available online. I've made a few changes to my recipe and technique since my article, but the original version of "Your Father's Mustache" is still a fine beer. Then I used flaked maize and hopped to a target of 25 IBU. Flakes are easier than grits or cornmeal, which I now use, but not as much fun, and cooking the corn with malt adds to the flavor. I also now use first wort hopping and hop about 50% more. >Would the style have been more Germanic or Bohemian viz. >color, attenuation, FG, hops? I think the style is more German in roots and similarity, but there certainly were pre-prohibition brewers in the US from both areas. The styles may not have so well defined 100+ years ago. I think there could well have been American interpretations of many European lager substyles, but nearly all would have used corn (or rice and/or sugar) as well as 6-row malt and domestic (Cluster) hops. The diacetyl that is typical of Pilsner Urquell (German brewers disparage it as "Diacetylator") is absent in modern German and American lagers, but was definitely at perceptible levels in US lagers in the past. Fix reports " Brewers' awareness and acceptance of both diacetyl and 2,3-pentanedione have changed dramatically over the past four to five decades. A 1952 report, for example, stated that the average diacetyl level of American commercial beer was 0.33 mg/L, more than three times the flavor threshold of 0.10 mg/L "Diacetyl: Formation, Reduction, and Control" by George J. Fix, http://brewingtechniques.com/library/backissues/issue1.2/fix.html). I definitely don't like diacetyl in this style and strive (successfully, so far) to avoid it. >I'm thinking American 2-row, maybe a pound of carapils for a >little "ass" (out of style, I know) I'd recommend skipping the carapils first time. I like the style to be crisp, and have I trouble in the opposite direction - often it's a little too sweet. Probably my mash schedule. But, hey, it's your beer! > and corn. I think you have said that grits work. What kind? >Instant? Regular? Yellow? How do you recommend >gelatinizing it? I've used instant grits, and any should work, but most of the time I use yellow corn meal. A local bulk food store has coarser meal than the grocery stuff (like Quaker) in a cardboard carton - it's very fine. But I've used it too. It does need to be gelatinized, and that's where the fun (I mean it, no ironic use of the word "fun" here) comes in. A typical 5 gallon recipe might be 7 lbs. malt (I like 6 row for authenticity and super enzymes, but use 2-row if that's what you have) and two pounds corn. You mash (this is a minimash called the cereal mash) corn:malt at 3:1 (maybe 2:1 if you have 2-row) with treated water (enough Ca++, low alkalinity, low sulfate, I use CaCl2) to ~153F -with enough water to avoid scorching. Hold it for maybe 20 minutes (complete conversion isn't necessary), then boil it until it's completely gelatinized. Be sure you have enough water and stir occasionally. Old texts say boil 45 minutes for corn meal, 75 minutes for grits, but no one does it that long commercially any more. I go for 30-45 minutes. What you're getting here beyond gelatinazation of the starches that weren't converted in the cereal mash is melanoidin production for flavor and some not undesireable darkening. Then you add this to the main mash which you have appropriately mashed in a bit earlier so it is ready to be boosted to the next temperature just when the cereal mash is ready. In other words, you could dough in the main mash at 140F as soon as the cereal mash is boiling, then add the cereal mash to boost to 158 for 1/2 hour. You'd need some additional heat such as a RIMS or boiling water. >Can I do a single step infusion, or do I have to do the >dreaded protein rest? A high one(130+) or a low >one(120+). Saccharification around 151-153? You could certainly do a straight infusion, especially if you use flaked maize. If you use a cereal mash, then you could either do two steps, or cool it before adding it to the main mash for one temperature rest. Or you could do a protein rest, probably at the higher temperature. Arguments here suggest that there is no reason for protein rest. I dough in at 40C (104F) and hold it while I get the cereal mash going, then boost using my propane fired RIMS to 60C (140F) during the time the cereal mash is converting. I figure that in 20 minutes or so it takes to go from 40C to 60C, I've passed through all kinds of useful temperatures. I have no problem with head retention or body. Then I rests the main mash at 60C (140F) while I boil the cereal mash, then add it and supplement with heat to get the whole mash to 70C (158C) for 20-30 minutes. Then I mash out and lauter. I also hop more than in my original article, to upper 30s IBU including the FWH contribution. FWH is an addition, also. I use Saaz or Hallertauer for this, but stick with Cluster for bitterness. >Fermentation tips. I have a 'fridge and I bottle. First, pitch a lot of yeast. The yeast from a 2 liter starter is not too much. Aerate well, and ferment around 50F until gas production nearly ceases - 10-14 days. Rack and lager 6 weeks, then bottle with corn sugar as usual and age 2 weeks at cellar temp for carbonation. You don't need fresh yeast. Good luck and have fun.

Date: Thu, 02 Jul 1998 20:18:30 -0400 From: Mark Tumarkin <mark_t at ix.netcom.com> Subject: bottle cappers Shannon writes about broken bottles when capping with a two-hand double lever type capper and asks: >Has anyone else had bad experiences with these type of cappers? I am >thinking of getting a bench capper. Is there less of a chance of >breaking bottles with a bench capper since nothing wraps around the >top of the bottle? You don't mention what type of bottles you were using. If they were screw cap bottles they are much more likely to break in any event. I used the lever type capper when I first started but soon switched to a bench capper. I didn't have many broken bottles but it is much easier and faster to cap a batch with a bench capper - trying to keep the bottle steady while using both hands on the capper left me wishing for a third hand. More importantly, I think it is easier to get a good seal, even and tight, with the bench capper. - ------ my 2 cents on the current Vampire thread (the Undead topic that refuses to retire to it's grave long after it should have given up the ghost) - I'm one of those newbies (although I'm almost beyond that status after 2 years and 20+ batches) that haven't been driven away or been put off by the techno-brewer guru gods of the HBD. In fact, thanks to you all. The HBD is, by far, the best brewing resource going. I am about to make the plunge into all grain. So now I find myself going back to the archives and looking up topics that I remember being discussed, but didn't pay that much attention to as it wasn't directly useful at the time. On the other hand, I almost never "page down" - reading computer & software manuals taught me the value of skimming even stuff your not going to use now, just so you know that the features exist so you can look them up later when you need the info. I'm not ready for RIMS and I don't understand much about chemistry, but I pick up little pieces of the puzzle and they may come in handy later. It's pretty cool when the puzzle pieces start to fit together and make sense. And, in part, the repetition of threads over time helps that eventual understanding. As far as "attitude" - yeah, folks on the HBD sometimes let things get blown a bit out of proportion - but hey who doesn't from time to time. Do you all read other news groups on different topics? Some of them get downright vicious. My wife follows a group for her profession that makes you understand the origin of the term flame. I think most HBD posters are generally pretty civil, and as far as "lighten up", one of the things I like most is the humor people display. Maybe one problem is that dry, sarcastic humor can be missed or misinterpreted - but, hey, don't let that stop you (it certainly won't stop me). For example, if Pat Babcock would quit wasting his time as janitor and post more, the humor level would be much higher. Well, thanks again to all of you, Mark Tumarkin Return to table of contents
Date: Thu, 02 Jul 1998 22:04:56 -0600 From: Michael Lausin <soscc at cmn.net> Subject: octoberfest has anyone been associated with a group that has put on an publicly attended octoberfest type funtion in their town? our brew club, the moffat county outlaws, is wanting to establish a yearly event around octoberfest time to help draw in the tourists. lining up the microbreweries to come has been no problem (usually never is where beer is concerned). we have some buy in from the city and the downtown merchants association, as far as "it's a good thing to do" and "we'll support you". what ever that means. we more curious about the legal hassles that we might need to know about like can we serve homebrew, liability insurance, etc. to save myself from catching any grief from the bandwidth gods, please reply via e-mail. if there's enough interest i'll post a summary of what i have found out from the collective. tia & cheers!

Date: Fri, 03 Jul 1998 15:14:54 +1000 From: Jon Bovard <jonbovard at geocities.com> Subject: Cylindroconical opinions wanted.. Greetings all. Last Sunday I went to visit arguably one of Australias most sophisticated home-breweries. This bloke had spent the better part of thousands and thousands of dollars on anall stainless steel and copper reticulation mash, fermentation and serving apparatus. The one thing i instantly fell in love with was his cylindroconical stainless fermenter. (see it here) http://www.geocities.com/NapaValley/3451/jim3.jpg My beers all suffer from a Truby taste associated with my inability to aseptically drain excess trub and debris transferred from the cooled kettleas mentioned in previous HBD. My question is what are the advantages of such an apparatus? Is it really worth it or is it like owning a BMW instead of a Ford? ie.Status symbol. Im keen to know if its worth it or not.

If > you are able to keep your beer in a cool and consistent environment, > any flaws in the process are less likely to become evident. If your > beer is subjected to agitation and heat, any flaws will all too > quickly become evident. I understand the damage heat can do to beer, but I don't understand how mechanical agitation can do damage. Anybody care to explain this? - ------------------------------------------------------------------------ I have a thought concerning posts on the HBD. Seems to me that most postings fall into 3 catagories: questions, answers and comments. I don't know if this would work, but would it be possible for posters who are giving honest *answers* to put some code in with their post so that we can save time doing our searches? When doing a search we could put XYZ+botulism. This would eliminate at least half of the search engine responses. Just an idea.

Date: Fri, 3 Jul 1998 05:47:56 -0400 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: Crystal - but not clear/Kubessa Scandrett/cappers Jeff Renner asks about crystal (and similar) malts and their fermentability. Is low fermentability a momily ? M&BS describes the general procedure for crystal mfgr and states that "A pale crystal malt called 'cara-pils' is prepared that yields an extract having low fermentability.". No clear explanation is given. Even tho the malt is 'stewed' for 2hrs at 65C-70C the modification may be incomplete due to lack of water for enzymatic hydrolysis. For darker crystal we can imagine that caramelization, and a limited amount of melanoidins cause fermentable sugar losses. The higher kilning temps *may* also cause some sugar binding changes - tho' I thought these were pretty stable. One thing is certain - some of the incredible flavors from crystal are due to thermal reactions between sugars and amino acids that form cyclic chemicals that include carbon and nitrogen in the rings. Pyrazines - some similarly transformed sugars become furans, and pryoles. The phenols in highly kilned malt products are also transformed into some that do not naturally occur in malt/barley. So could the kilning transform some of the 1-4 sugar bonds (which the amylases can handle into 1-2 bonds, 1-6 bonds etc ? I don't know. I guess I'm saying that good sources support the idea that crystal malts give extract of low fermentabilty. It's probably no momily. I'm pretty sure I don't know why. My speculation is that the sugar bonds are disturbed thermally. - or true caramel is formed. The process described for making caramel (sugar and ammonia - a nitrogen source, cooked for 3 hrs at 120C) don't sound so radically different from the way crystal malts are kilned after stewing (121C till color is achieved). - -- AlK writes re GeorgeDP (is the abbrev OK with you George ?) and the Kubessa process and is on target about the percentage of total phenol found in the husk being only a small fraction of the total. That isn't to say the the husk phenols might not be the most troublesome tho'. The types of phenols found in the husk fraction are distinguishably different that those in the germ. For example ferulic acids, the precursor to the 4VG wheat beer taste is far more concentrated in the husk fraction of barley - removing the husks till end-of-mash should prevent their enzymatic release. Also the gums embedded in the husk fraction to which phenols are attached aren't solubilized in the mash in the Kubessa process. I'm afraid the only way to tell if it works is to try it. BTW Charlie Scandrett proposed the Kubessa process - tho' not by that name on HBD well over a year ago. I *believe* he claimed that leaving the husks out altogether produced an insipid product - but maybe I'm misstating the facts from faulty memory. - -- BTW - tongue in cheek for Shannon Miller - the best bottle capper is the really frustrating hard to use one you already have since it will cause you to give up and lay out the $$ for a keg setup. You'll never regret it. Steve Alexander Return to table of contents
Date: Fri, 03 Jul 1998 06:56:39 -0400 From: Fred Johnson <FLJohnson at worldnet.att.net> Subject: Burning propane in closed room. I have always taken precautions to keep the garage door open when I'm brewing with my propane cooker to avoid the buildup of poisonous gases. However, last night I visited one of my local discount megastores in which there was a guy using a large floor polisher powered by a combustion engine fueled by what appeared to be a 20-30 pound propane cylinder. There were some fumes in the air but they were not obnoxious. Was this likely to be propane being burned and if so, how could someone get away with marketing such a machine, apparently intended to be used indoors (how many floor polishing does one do outside?) unless the combustion products were safe? So, what about my propane cooker? Must I leave the garage door open when I brew? - -- Fred L. Johnson Apex, North Carolina Return to table of contents
Date: Fri, 03 Jul 1998 08:28:24 -0400 From: Mark <mark at maine.rr.com> Subject: First Batch........ Hello: Yesterday I opened my first bottle of West Coast Pale Ale made with my QVC special prices Mr. Beer, man was it cidery! Followed the directions to a "T", but instead of bottling for 1 week, I gave it about 12 days. I'll let it sit in the cellar for a couple of weeks more and see from there. Second Batch: I started a batch on Munton's Premium Bitter using 1/2 can in my 2+ gallon Mr. Beer. To this I added 1 cup sugar. I'm told that this may be cidery as well, but may mellow out in time. Third Batch: Last night I started the other half of the Munton's Bitter using NO sugar. I guess I'll find out in a few week which is better. Finding home brewing very interesting and enjoyable. Being a former chef (I'm on my second career in life) this fits right into what I like to do. Recipes, formulas and experimentation are what I like to play with. Maybe I should be a scientist in my next career move! Just as an FYI, I prefer using the easy cap bottles for obvious reasons. I bought my first two cases and was hurting for an other dozen so my local beer supply shop keeper gave me a dozen from his private stock. I'm cleaning out the bottles from the garage today and will see if the redemption center has any others.. Cheers! Mark Return to table of contents
Date: Fri, 03 Jul 1998 05:45:25 -0700 From: Bob Wilcox <bobw at sirius.com> Subject: No Sparge Hi John Looks like a good brew and no sparge has made a big differance in my brews. I use that method with most of my beers now. The only thing I would change in your recipe is the amounts of grains. For a 5gal batch without sparging I use 12-13 pounds of base malt and up the specialty grains a little. I think you need to add a third more grains. I add water to the kettle to bring it up to 6.5 gals. Good luck and I think you will like the results.

Pritchard" <cdp at chattanooga.net> Subject: re: homemade coolers Steve Alexander posted: >In the past I've entertained various ideas for fermentation/lagering designs >and in the end I always find that once any reasonable allowance for >construction effort and the cost of pumps, fans, insulation, material, temp >controller is included a used fridge or freezer with controller looks pretty >attractive - a la Fred Kingston's recent post. Even new low-end chest freezers >look pretty good. Do any cold box, fridge extension builders care to disagree ? I've built 2 differently designed ice powered fermenting chambers and have to agree with Steve- a chamber fridge or freezer is a heck of a lot easier done and, if you put any value on your time, less expensive. IMHO, the biggest disadvantage of ice powered coolers is that replenishing the ice can be a big problem (or nag factor <g>) if you have to rely on your better 1/2 to tend to the task while you're out of town. c.d. pritchard cdp at chattanooga.net http://chattanooga.net/~cdp/ Return to table of contents
Date: Fri, 03 Jul 98 09:41:37 -0400 From: Dave Humes <humesdg1 at earthlink.net> Subject: Water treatment Greetings, I'm starting to take water treatment a little more seriously and so have what are no doubt some rather basic questions. My water is fairly soft, so to get the desired profile for a "westernized" India Pale Ale, a simple CaSO4 addition looks like it will get me pretty close. I've looked through all of the standard homebrewing books and found it rather simple to come up with the desired amount. It just seems to be a lot. I'm shooting for a Ca concentration of about 170 ppm and a SO4 concentration of about 400 ppm. It's a 10 gallon batch with 6.5 gallons of strike water. Doing the calculations I come up with 18 grams of CaSO4 to treat the 6.5 gallons of strike water. If you are simply trying to effect reactions in the mash, then obviously you only need to treat the strike water. But, then it seems like if you are really trying to match the brewing water of a given region, you have to treat the sparge water as well. So, that's another 28 grams in 10 gallons of sparge water. Your opinions will be appreciated. BTW, I'm starting this batch in about 30 minutes, so if anyone on DC-beer can respond quickly, that would be appreciated. Cheers! - -- - ----------------------------------------------------------- Dave Humes <humesdg1 at earthlink.net> Dave Humes - ----------------------------------------------------------- Return to table of contents
Date: Fri, 3 Jul 1998 11:43:40 EDT From: AlannnnT at aol.com Subject: propane in the basement brewery and no boil beer Randy writes, "I know this subject has come up before, and there are a lot of people who will argue "don't do it" ( and I respect that opinion), and I also know there have been a number of people who have posted that they do it with no problems." ['It' being propane cookers in the basement] Randy, the possibility exists that the people who would argue that they have done it and they now think it's not safe, have already killed themselves. As the brilliant Dennis Miller says, "That's just my opinion--I could be wrong" - ------------------------------------ On the subject of no boil extract brewing. The recent discussion of no-boil prompted me to try a no-boil beer from a Muntons kit. I steeped one pound of cracked crystal, briefly [2 mins] boiled 6 gallons of filtered water with an ounce of leaf hops. Added the two cans of Muntons IPA, one pound of dextrose and a half pound of DME. Turned off the heat, force chilled [sorry Jack] with my newly made, all stainless, Bride-of- Imersion-Chiller. Fourteen days of fermentation and two weeks of conditioning later, I have the world's least interesting beer. I am certain my non-brewer friends will like it. I have made decent beer from extracts before, some even excellent {IMNSHO}, but this is neither. Since this is just one experience, not a conclusive experiment, I would like to know if anyone has had a better experience. Best Brewing, Alan Talman Return to table of contents

Date: Fri, 3 Jul 1998 11:55:56 -0500 From: bpgarner at mailbag.com (Bruce P. Garner) Subject: Re:Convert a sausage grinder Dave Russell writes: >I came into possession of my grandfathers old sausage grinder and was hoping to >use it as a grain mill. It doesn't augur well for your being able to adapt a grinder as a grain mill; at least on your present tack. A sausage grinder sends pieces of meat toward a cutting plate rotating against a fixed plate to duplicate the action of someone repeatedly and at different angles chopping up and down with a cleaver. (In England ground beef is called mince.) The best you can hope for is that most of the grain, husk and all, would be minced into smaller pieces. Milling grain for brewing involves crushing it so that the husk pieces stay full length to create a filter bed and the insides are in smaller bits but not floured to allow full wetting during the mash. This is similar to what one would do using just enough action with a mortar and pestle, hammer or rolling pin, were they to do it by hand. You might be able to get milling plates for the grinder that allow it to operate like a Corona Mill. But many who have a Corona as their first mill move to roller mills because the Corona needs to be alined properly to avoid an uneven crush and with hand grinding most batches take too long to put through the mill.

Date: Fri, 3 Jul 1998 13:55:57 -0400 From: droot at concentric.net Subject: Mash Volume in Kegs WayneM38 at aol.com asks how much space 5 gallon and 10 gallon mashes take up in a Sanke keg. I mash mostly 10 gallon batches in a 1/4 (7.75?) gallon converted Sanke. 24 Lbs. of grain will fill it to the rim with 5.5 gallons of water. Last Sunday, I used 30 Lbs. of grain and brewed 5 gallons of 1.090 beer, and 10 gallons of 1.044 beer. I used the 1/2 keg, (15.5) gallons and it was ~3/4 full. I started with 7.5 gallons of water (the 1/2 seam) and added the grain. I also added 2 gallons of boiling water to help go from 40c to 60c.

Date: Fri, 3 Jul 1998 11:26:27 -0700 From: "Hunts, Jeff" <jhunts at CIWMB.ca.gov> Subject: Wind Screen / Heat Shroud / Hot Metal Wise and (usually) Gentle Collective: To get the most out of my propane tank and my one keg / one burner set-up, I took the advice of an HDBer who suggested several months ago using a galvanized trash can as a heat shroud. I bought a spanking clean and shiny 30 gallon galvanized can with lid from the Home Despot for about $15. Cutting the bottom out was easy. Tin snips would've probably worked if I had some, but I just used an old chisel and a hammer and banged it out. Cut like butter. Flatten the sharp edges with the hammer. Anyhow, the can fits inverted over the keg brewpot perfectly, resting on the tripod legs of my 170K btu burner to keep it off the ground allowing good air flow, with the top rim of the keg extending a few inches above the *base* of the inverted can. (I believe the HBDer who suggested this technique used a wire hanger to suspend the can over the keg.) I use the trash can lid (still nice and clean) as a protective cover on the keg while boiling, with steam exhausted through the kegs handle holes. And the wire loop handles on the trash can make it easy to slip on and off even when hot. I can keep a good boil going with minimal flame. I originally worried about the plastic coating on the ball valve handle melting (as well as any exposed teflon tape torching), but the bottom skirt of the keg seems to contain any direct flame. My related question today: Metal guru Jim Palmer in HBD#2757 warns against letting certain species of SS overheat. That bottom skirt on converted keg boilers gets pretty darn hot, what without direct contact with boiling wort keeping it in the low 200s F. Also, when I'm through with the boil, and before chilling, I use a hose w/ a pistol sprayer to mist off the lower portion of the keg, resulting in much steaming and sizzling on that hot bottom skirt. There is some discoloration of the skirt from this heating and cooling, but what are the consequence of this procedure? Catastrophic skirt failure? Boiler rupture? I'd hate to have five or ten gallons of boiling wort explode all over my deck -- and feet! Any insights welcomed.

From: Nathan Kanous <nlkanous at pharmacy.wisc.edu> Nathan asks about beer foaming and line length. >Help! Nathan, you left out the one thing that we wonder about most - how long? More inportant than the length, would be the inner diameter of the lines. Ideally you would want 3/16 ID about 5 foot long. This will allow you to keep the beer carbonated and use about 10 PSIG to move the beer. Also, you need to open your beer tap fully when dispensing, if you partially open, you will get much foam. Keep the line cool, I have had some foaming when the line gets very warm. Ron Ronald La Borde - Metairie, Louisiana - rlabor at lsumc.edu Return to table of contents
Date: Fri, 3 Jul 1998 17:25:59 -0400 From: dbgrowler at juno.com (michael w bardallis) Subject: Keg lines too long? Nathan, You didn't say how long your lines are, or what ID, or material, but I doubt that's your problem. I'd say your regulator is set too low! You see, beer at 40 deg. and 1 psi will equilibrate at about 1.4 volumes of co2, which is kind of low. (most beer falls between 2.0-3.0.) You didn't mention your method of carbonation, but if you either primed or force carbonated the beer to a higher level than 1.4, the co2 in the beer will take any opportunity it can to get out of solution. Opening the tap, plus a pressure drop across any restriction, plus any turbulence: we're talking foamarama! The correct pressure setting will be based on your beer's desired carbonation level and keg temp, plus the pressure needed to push beer out the tap at the desired rate. Charts showing dissolved co2 for various psi/temp combinations have been published in The Homebrewer's Companion and Beer and Brewing, vol. 10, as well as various periodicals. As an example, if you want to maintain 2.5 volumes at 40 deg F., you'll need to put about 12 psi on that baby, plus a little extra to push the beer out, say 2 psi. (it don't take much) Depending on how full your keg is, and how long it's been slowly degassing, it may take a couple of days for things to re-equilibrate.

Mike, I believe these are reasonably accurate. I forced feeler gauges into the roller gap for each position on the mill. (The reason I forced the feeler gauges is that when grain works its way through it will try to spread the rollers.) The lines on the mill do not line up well with the indicator on the roller so I redrew them with a marker and marked numbers accordingly. I also used a torque wrench and tried to get a reasonable idea of torque requirements. I found that Schreier 2 Row pale at setting five required around 35 inch pounds of torque to turn the rollers Grain Mill Settings 1 0.019 2 0.025 3 0.035 4 0.049 5 0.065 35 in #'s torq 6 0.083 - -- My All Electric RIM Brewing System "http://www.mcs.net/~rnr" Return to table of contents

I used to try and strain the hops out using a kitchen strainer but found it to be a PITA. Now I dump the whole works into the plastic pail and let it churn. Two days later it gets racked into the secondary and off the trub, it's easier and keeps my brew time down, beer tastes great. Sanitation notes: I once lost my rubber air lock grommet in my pail trying to jam the air lock in, I went fishing in the wort with my arm almost up to my shoulder. I expected an infection but it never happened. Seeing this, I then experimented with bottling. Since bottling is the biggest PITA associated with this hobby, I skipped the chlorine soak and simply rinsed with our excellent local tap water, no infected bottles after 200 tries. Perhaps I'm just lucky or maybe we worry a little too much about killing every last bug. Anyone had any experience with YeastLabs Dusseldorf Altbier yest out there?

I have used both in the past and have been >pleased with the results. anyone have thoughts on choosing one over the other? I have only used Muntons extract once, so I can't really compare the two. However, Alexander's has been my standard extract. Although I also like NorthWestern (Briess?). I had read that Alexander's gives the one of the lightest worts, and I can confirm that it does. This is important with with extract as it is harder to get a light beer than with all-grain. It's always easy to get more color or flavor, when desired, from a partial-mash of specialty grains. Most other extracts seem to yield a darker color - even when they are called light or extra light. Alexander's also seems to ferment cleanly and completely. If they are the same price, Alexander's would be my choice. Mark Tumarkin Gainesville, Fl Return to table of contents

I have heard > rumors and whispers that this is BAD. Oh someone, please tell me why. It ain't. Jeff Oh, I suppose you want the long answer. ;-) This is one of those threads that comes up every few months and there are hotly held opinions. Fortunately, I have a purely reasonable, unemotional position on this. And I'm right, too! First objection is that aluminum, one of the most common elements in the earth's crust, was in one study some yeasrs ago implicated in Alzheimer's disease. That association has has been disproved as a causitive factor, at least as much as a negative can be proven, and the archives have documentation. Besides, the Al doesn't even get into the wort - a BT article documented this. Second is that commercial breweries don't use aluminum. This is because it reacts dangerously with caustic (NaOH) that they use for cleaning in place. We don't use that stuff, so it's OK. Advantages - Aluminum has 10x the heat conductivity of SS (according to a HBD post several years ago), and it is more easily wetted, so you don't get hot spots as easily. It's light weight and less expensive than SS. I paid $220 for three 10 gallon, 5mm thick stock pots with lids. These work great in my bottom fired 1/4 bbl. RIMS.

I didn't see if there was an answer to this question, but here's mine...As you point out in your question, 212F water and 212F steam are the same temperature, therefore neither is "hotter", but....steam will impart more energy to whatever you're heating up. The steam will condense on the the items releasing the heat of condensation. This energy will raise the temperature at the surface of the item above 212. Its the same idea in reverse as to why evaporation cools something. Mike Return to table of contents
Date: Sat, 04 Jul 1998 11:10:40 -0600 From: "Larry O'Mahoney" <breck at communique.net> Subject: Hop Combination In order to try a thread of a different type, I thought I'd ask for peoples' various tried and true hop combinations. I've found certain hop combinations work better than others for various styles, and I'm sure other brewers have too. For example, one combo I've found to be particularly good is Perle (bittering) and Ultra (aroma and dry hopping) in English pale ales (33 IBU) using Wyeast 1007. It provided an incredible hop nose like nothing else I've ever tried. Another favorite is Chinook (bittering) with Cascade (aroma and dry hopping) in an IPA (45 IBU) with Wyeast 1056. In addition to my brew, I've tasted several brewpub offerings with these hops and they were pleasant brews as well. Alright, in order to introduce some controversy (this is the HBD after all) you might also post what didn't work. I tried an all Galena hopped pale ale (40 IBU) (FWH, bittering, flavor) using Wyeast 1007 that I couldn't stand. I'll never use Galena again (my neighbors loved it, so it's not a total loss).

Neitzke" <neitzkea at frc.com> Subject: Crystal malt discussion In a response to Jeff's discussion of crystal malt, I have a single data point. I ground 2.5 lbs of 60L crystal and "mashed" it at 158F for 20 minutes and did a iodine test, it was black as coal! I let it continue to stew just to see what, if anything, would happen. After 40 minutes the iodine test was still "black as coal", the same results occured even after 1 hour. >From all the information I have read and been told about crystal, is that it was all sugar and did not need to be mashed! This doesn't seam to be the case. I will try to get the spec's on theis malt, but I would encourge other to try the same thing with their crystal malts, to see if this is consistant. You probably will not have to use as much malt as I did, since I was going under the assumption that the iodine test would be negative and I was going to try to make beer based on crystal only. If it did show negative, I was also interested in finding out just how far down the wort would have fermented? _________________________________________________________ Arnold J.
