---------------------------------------------------------------------- Date: Fri, 09 Jan 1998 04:52:40 -0500 From: Steve Alexander <steve-alexander at worldnet.att.net> Subject: Re: phenolic extraction with RIMS/Malt conversion % This is a very difficult question to answer, One study from (Von Narbiz, Brauwelt, 1979) indicates that thinner mashes (4:1 and 5:1 water:grist, versus 3:1) had greater phenolic extraction. The same study also shows that longer mashes (180 and 360 minutes versus 105 minutes) had lower phenolic extraction (but worse flavor). Is cycling the water thru a RIMS equivalent to adding more water ? Well yes and no. Experience says that a RIMS doesn't create phenolic related problems, tho it'd be interesting to see a test. - -- How much malt is necessary to convert your adjunct ? This depends entirely on how you treat your enzymes. If you mash in at 65F, your beta-amylase will be toast before it has a chance to convert enough starches to maltose. If you mash using a 60C/70C schedule you can usefully extend the hold time at 60C and get a complete conversion and normal fermentability levels. The rules of thumb are apparently based on single infusion mash conditions. The whiskey industry regularly mashes using no more than 30% 6-row malt, a low temperature mash and pre-gelatinized adjuncts getting maximum fermentability. I have no doubt that 10% malt figures are possible. How much diastatic power fron various malts ? >From the BT 1997 Market Guide, some typical figures ... Barley Malts: US 6-row 140-160 Lintner US 2-rows 110-130 Lint Continental 2-row 60-110 Lint US pale ale 100-120 Lint Brit Pale Ale 40-60 Lint Wheat Malts: Crisp, Breiss & Gr.Western & Schreier 120-165 Lint Brew.Prod., DWC & Gambrinus 70-100 Lint. Rye Malts: N.American 95-130 Lint I wouldn't sweat the wheat malt conversion. Steve Alexander Return to table of contents

As St Patty's day draws near we start to plan our annual St Patty's day bash, this year I've decided to add a stout faucet to my draught system and I have some technical questions. First off, I completely understand the balance of a draught system, I haven't touched my regulator in almost 2 years, it's always at 13 lbs for carbonating and dispensing, so that being said, here's my questions. 1) how many volumes of carbonation is optimal for a stout that is destined to be pushed with a N2/Co2 blend? 2) I will be purchasing the variable restrictor stout faucet from Banner, but in general, how many pounds of restriction does a stout faucet have? Thanks! (PS Any award winning "KILLER" stout recipes, either sweet or oatmeal would be welcome.) I've perused CP's latest book of World Cup Recipes, and the stout recipes look interesting. ************************************************ A thought comes to mind, has anyone ever pasteurized a cornie keg before? It would seem simple enough to drop it in a half barrel, fill the half barrel with water, take the cornie out, bring th water up to pasteurizing temps (155?) and drop the cornie back in for a half hour or so. any thoughts? Talk amongst yourself, now I'm verklempt. Regards,_Rich Byrnes Jr Pre-Production Systems Analyst \\\|/// phone #(313)390-9369, fax #390-4520_______o000_(.)

Date: Fri, 09 Jan 1998 07:44:02 -0500 From: Jim English <jimebob at mindspring.com> Subject: "bitter beer face" Stepped up to full volume boils on the last two batches of extract brews and I think I may have screwed up in the specialty grain steeping area. I adapted my old small-pot method and steeped in the full volume of water to 170 degrees F , removed the grain bag and proceeded as per usual. I knew I would get much better extraction from the hops but figured, " what the hey". One batch is pushing 6 weeks in the bottle and is way bitter/harsh. I haven't even tried the other (4 weeks) yet. Did I extract tannins from the specialty grains due to the volume of water? TIA JRE Return to table of contents

Wow, never had that - at least not in Praha, but I never went to Plzen, but sounds like she was having package meals. Hope she didn't get ripped off... >She brought me back four bottles of Urquell and one of >"Gambrinus >White". >The Gambrinus Dark broke along the way. >Does anyone know what >Gambrinus White is? She means Gambrinus Light - meaning in colour, not alcohol. Just like Germans have "Helles" and "Dunkel/Schwarz" the Czechs have "Svetle" and "Tmave/Cerne" (There is no AHA category for Czech dark beers - although you would probably enter them as German dunkels). There is an upside down caret over the first e in Svetle and over the C in Cerny. There are accents over the last e's. Pronounce as such: "Svyet-lee" "T'mav-eh" "Chern-eh" So your Gambrinus is in fact a true straw coloured Pilsner. You will enjoy it if it hasn't gone off. This is likely as Czech beers travel extremely badly, but it might still be OK. Your best choice is to go over! You won't regret it. The Czechs also rate their beer in Plato - though the usually use a "%" instead of a degree. The Gambrinus you will try has "10% svetle z Plzene" on the label and the label is silver with a white (ah-ha!) diagonal stripe with Gambrinus in it. Gambrinus svetle 10 is 4.1% abv. I prefer Gambrinus 12 though - and all Gambrinus over Urquell. Mest'an is my fave though. I spent a month in Praha(Prague) in July/August this year and collected heaps of labels along the way!

My question: can this be alleviated by extended lagering, or should I just proceed as normal, get a less-than-optimum result, and chalk it up to experience? <<<<< Gee Dave, what a chance to experiment. I don't know how you'll end up, but I hope you'll consider normal lagering some for extended lagering for some, and no lagering for the rest?. Then you can do the "double blind and deaf" (tm AlK?) taste test with you and some friends to evaluate the results. Then let us all know how it turned out. I'm no certified beer judge, but I might even make the drive up IH-35. ;) On another note, I will be in Montreal the last week in January and will have some free time, especially Sunday the 25th to check out any interesting local beverages. Anybody from up that away care to make suggestions? Merci, mon ami. Regards, Lou in Austin <lheavner at frmail.frco.com> Return to table of contents
Date: Fri, 9 Jan 1998 09:44:23 -0600 (CST) From: Paul Henning <phenning at cs.uiowa.edu> Subject: Traquair House Ale & McEwans Scotch Ale Thanks to the tenacity of one of our local liquor stores, we are finally getting some "bigger" beers in Iowa. Among the large collection of Belgians and doppelbocks that have recently arrived, there is a cache of Scottish beers, including Traquair House Ale. That beer certainly lives up to the rave reviews I have heard on HBD and elsewhere. However, it also introduced a little confusion. I was expecting a strong Scotch ale, which I had previously equated with McEwan's Scotch Ale: HUGE malt aroma and body. Not that THA doesn't have malt; just not so overwhelmingly so. I'm wondering if someone wants to straighten out my beer taxonomy. Are THA and MSA different ends of the same category, or is THA a "scottish ale" rather than a strong scotch, or is MSA just an anomaly?

Date: Fri, 9 Jan 1998 11:00:12 -0500 (EST) From: Tidmarsh Major <tmajor at parallel.park.uga.edu> Subject: re: Keeping warm Nathan in Frankenmuth suggests that Tony Willoughby build Ken Schwartz's fermentation chiller and perhaps use a ceramic heater to raise his too-cold fermentation temps. I don't remember how cold Tony's fermentation was, but for a more low-tech approach, how about using gallon jugs filled with hot water (either from the tap or heated a bit on the stove)in place of ice-filled jugs? It may provide enough warmth to keep the fermenter in the proper temperature range while at the same time retaining the admirable simplicity of Mr. Schwartz's design.

Date: Fri, 09 Jan 98 11:10:51 EST From: SBireley at renex.com Subject: mash mixing, RIMS, fermenter temp. control, sparging I have evolved as a brewer, like most on HBD, from extract to all grain, and in the process tinkered with alot of ideas to improve the process. Brewing appeals to the tinkerer in me and taking a hobby the Nth degree is the only way I do it. I see this applies to many others. To quote a friend it the high-end audio business " Anything worth doing is worth doing to excess." We have been brewing using a recirculating pump in the Mashtun for some time with great success. Using a false bottom, magnetic drive pump, four outlet sparging arm (courtesy of someone's RIMS page) and thermocouple adapter for a DMM, we achieve excellent, stable temperature profiles throughout the mash, fast boost times, easy (but manual) temperature control, and good extract efficiency. We do 3 step infusion mashes and have found the key to be placing the thermocouple probe in the outlet of the sparging arm and regulating the heat based on temperature of the wort being pumped from under the false bottom. Once the target temperature has been achieved, we profile the grain bed to verify the target temperature has been achieved throughout, then reduce the heat to maintain the target temperature. We use an uninsulated sankey keg as the mashtun, therefore, some heat must be applied to maintain the target temp. This is not an automated RIMS, but it works well. Additional automation is sure to come. Though this has worked well for us, combining this system with an automated mixing system seems like a good idea. We will have the advantages of recirculation; clear wort run off, easy, fast boosts, no scorching, and the advantages of the mixer; less manual labor, very consistent temperature profile, and maybe increased mash efficiency. We intend to build a mixer set up and experiment with it. Any comments would be appreciated. In response to KEEPING WARM, I use a light bulb in the winter to keep the temperature in my fermentation refrigerator (in garage) at 55 deg. for ales. This results in a fermentation temperature of 63 to 65 during high krausen,it drops off some after that. ( I wrote in about this a few weeks ago concerning the effect of the temperature drop on the taste). I use the same controller for temperature control of both the compressor and the light bulb. The controller is for a heater and I connect the normally open contacts of the relay to the light bulb. When used for refrigeration, I connect the compressor to the normally closed contacts. This seems to work fine. I think a home type thermostat will work fine, but I think they are 24 volt. The 24volt transformer is available from a hardware store and a 24v coil relay from radio shack or like store. Is there a preferred method for determining when to stop the runoff during sparging? We use a lab quality PH meter to monitor mash ph, but stop our runoff at 1.010 gravity. I'm sure we are leaving good sugar in the tun, but we do not want to over sparge. Is there a rule of thumb?

Date: Fri, 9 Jan 1998 11:34:30 -0500 From: "Spies, James" <Jams at mlis.state.md.us> Subject: counter pressure bottling All - I just came into a few 5-gallon kegs cheap, and eventually plan on doing the kegging/filtering/force carbo-ing/counter pressure bottling thing. Eventually. As I was pondering the future, a question popped into my head. If one filters the final product and then force carbonates and bottles and/or kegs the filtered CO2'd beer, will the lack of yeast preclude aging or conditioning of the beer. Removing all of the stuff from beer is the reason that the Budmillors swill goes stale after awhile. Will the same thing happen to my brew if I filter/force? Will using a coarser filter allow some yeast to pass through? Perhaps some of the collective wisdom on this issue can be shunted my way. BTW, SABCO currently has reconditioned 5-gallon SS kegs on sale for $12. Not a misprint, just rock bottom prices. I picked up three yesterday. Point to www.kegs.com. No affilliation, yadda yadda, solely FYI. Hurry though. At $12, they ain't gonna be there long. TIA, Jay Spies Wishful Thinking Basement Brewery Return to table of contents
Date: Fri, 9 Jan 1998 11:37:03 -0500 From: Harold L Bush <harrybush at compuserve.com> Subject: Heaters for Mixmashing (Mashmixing, Maxmishing???) Hi- I've been netless, and therefore HBDless for just over 2 years and it= s good to be back. Glad to see Jack S. is still here, full of piss and vinegar. For the same 2+ years, I've <not> been putting together my new brewery, so I've returned to the HBD just in time to witness a good discussion of mashing methods/equipment. In the Tues., 1/6/98 HBD, Charlie Scandrett brought up the idea of using low density heating elements as the impeller blades in a motorized stirri= ng device. My question is: how would you get the power to them? I guess th= at if you look hard enough, you might find an off-the-shelf slip ring type electrical coupling to mount on the mixing shaft and run wires down the shaft to get the power (I presume in the order of 1 kW) to the impeller heating elements. I don't know if such couplings are available, or their cost (it probably wont be cheap, since it would have to carry in the area= of 8 amps at 120v). Anyone out there have any clues? I wont even suggest= the option of building your own slip ring device. 120 volts and a potentially wet environment (ZAP!) would make for too many design obstacles for most of us basement machinists. I, on the other hand, purchased a Rubbermaid cooler (10 gal) and a 5 qt. pressure cooker with the intention of doing step mashing with steam injection as my heat source. I assume that stirring would only have to be= done while heating. Is this a good assumption? And could any steam-hardened veterans (Charlie Scrandrett?) give me an idea of how long= it takes to raise mash temps with steam injection. Motorized stirring may= be a good idea for this setup. BTW, for those interested in the ultimate in mash circulation simplicity= , I have invented the StirringSpoon (no trademark, so you're free to infringe). It is a combination mash-mixer and wrist-forearm exerciser (as= always, please consult your doctor before beginning any exercise program)= consisting of a commericially available stainless steel spoon, friction tape for secure grip, and a hole drilled in the end to facilitate easy storage on your favorite hook.

First, you should have one of several introductory brewing books available. I'd recommend Miller's Homebrewer's Guide, but whichever you like. These questions should all be addressed in those books.

From lurking on the list for quite some time, I >get the impression this might actually be a good thing. How better >to control temps, and what temps to use? Not sure why your temps are increasing. You must be heating the mash directly, and then you'll get some rise in temps after turning off the heat. This is because the bottom of the pot gets hot. Anyway, the more you can control the temp, the more consistency you will get. But fluctuations in temperature won't affect your beer that much. Except if you get much over 160F, you'll really start to denature enzymes, and that will make for a very long mash. Since you are apparently only mashing a couple or three pounds of grain, I'd recommend using some kind of insulated box to put your mash tun in. After a few trials, you can figure out what temp of water (say, 168F or so) to add grain to so you can mash at 155F. You can also try putting your pot in a 155 oven, if your oven goes down that low. > > 3. I use two burners on my gas stove to heat/boil my wort.

Are we talking a full rolling boil, >gentle boil, what? You want a full rolling boil. Two reasons: you'll get better hop utilization and better hot break. A little scorching on the bottom won't affect you too much, as long as you can clean it off when you're done. You also want to boil for other reasons--you'll drive off more precursors to DMS, a corn-like flavor you don't want. You'll also sterilze your wort and concentrate your wort to the right gravity. Oh, the corn sugar thing. If you prime with corn sugar, you want it all to be converted to alcohol and CO2. None should be left to contribute any sweetness. In my experience, there's no difference between priming with sugar, honey, or malt. Maybe others will have a better explanation. I could go on, but hopefully this is helpful. - Bryan Bryan Gros gros at bigfoot.com Oakland, CA Visit the Draught Board club website: http://www.dnai.com/~thor/dboard/index.htm Return to table of contents
Date: Fri, 9 Jan 1998 11:57:34 -0500 (EST) From: Tidmarsh Major <tmajor at parallel.park.uga.edu> Subject: re:Maintaining steeping temps MMC Richard Kappler asks, among other things, how to steep grains at 155F without overshooting. What I've done for the past couple of extract/specialty grain batches I've done is put the crushed grains in a grain sock and put it in a stock pot with about a gallon of water heated to 160-165F, stabilize at 155F or so (adding heat on the stovetop if necessary), and place the pot, covered, in an oven set to "Warm" (~150F) for 30min to an hour while I heat the 5 gallons of water for the extract. I then drain the wort from the sock into the kettle and dunk the sock in the hot brew-kettle water to rinse a bit more sugar, and then dissolve my extracts and continue as usual. Also, boil time is time at a boil, not including the time to come to a boil. A full rolling boil is probably best for hop utilization, but I usually go with more of a gentle boil, to help avoid boilovers when I'm not looking.

Date: Fri, 9 Jan 1998 12:36:37 EST From: LBarrowman <LBarrowman at aol.com> Subject: Re: A question about yeast starters Danny, Sorry for holding out on you. I did try increasing the gravity of my starter substrate to ~2# per gallon. I still start them off with substrate at ~0.5#/gal (1 pint at 0 hours and 1 pint at ~24 hours) until I have added a quart. Then I add the higher gravity starter at 1/3 pint per day until the day before brew day when they get fed twice a day. This methods seems to work well. I get a lot more krausen and bubbling going on, but the amount of yeast appears to be about same as before. Lag times have been acceptable, ~8 hours, but longer, I think because my brew cellar is cooler this time of year. I have been making 3 starters at a time from a single wyeast pack. My last two batches have been 12.5 gal. using the first runnings to make a heavy. I have had no problems fermenting out the heavies, the highest had a gravity of 1.106 and the other 1.102. So, I'm thinking the yeast is pretty robust. I used Wyeast 2308 and 1318 respectively. Laura Charlotte, NC Subj: A question about yeast starters Date: 98-01-09 10:03:06 EST From: DBreidenbach at nctm.org (Danny Breidenbach) To: LBarrowman at AOL.COM Laura, In HBD 2556, 11 Nov 1997 you wrote: "I have had great success (lag time ~3 or 4 hours) by pitching my starters into a gallon jug with 1/2 pint wort and then feeding them 1 pint per day until the day before brew day when they get 1 pint every 12 hours. (starter substrate: 1# DME per 2 gallons) I usually end up with ~3 quarts final starter volume. I hate dumping off the liquid before I pitch because there are so many yeast cells suspended in it. I think the lazy (or dead) ones are lying on the bottom. "I am thinking about changing my method slightly to keep the starter volume down. Using my previous method (dilute wort), I would get the starter volume to ~1 quart and then begin adding small amounts (1/4 pint) of higher gravity wort. (substrate: 1# DME per 1/2 gallon) I think my yeast food is too dilute. By changing the gravity of wort fed, water is the only thing eliminated, resulting in the same amount of substrate (at the same rate) to the yeast cells." Any updates? I'm curious to know if you tried your new idea to keep starter volume down and how it worked.

I am happy to say you all helped out a lot and I am finally getting the gravities I was looking for. My biggest improvement has come from slowing my sparge rate to a tiny trickle. I have been having to stop spraging when my boil pot is full. The gravity of my run-off has been between 1.026 & 1.030 when I stop. This seems a little high to me. Should I be sparging out more wort? Should I track gravity or pH (or both) to indicate when to stop? Thanks again all, Laura Charlotte NC Return to table of contents
Date: Fri, 09 Jan 1998 10:28:22 -0800 From: Joe Stone <joestone at cisco.com> Subject: Computer-Controlled Brewing System I started designing my computer-controlled, RIMS-based brewing system in September 1994 with help from Bob "Mac" McIlvaine and others on the HBD. I brewed my first batch of beer with it in December 1994. I completed the final (?) phase of the brewing system in September 1996. I have finally completed (?) a web page describing the system, http://www.employees.org/~joestone/Sbs/ Yeah I know, "On no, not another brewing system web page." But this is my way of saying thank you to those who helped me and share the design with others. The web page design certainly won't win any awards, but hopefully the content will adequately convey the brewing system design, stimulate thought and spark new ideas (which you are obligated to share with me :-). I've invested well over $5,000 in the brewing system (I have over $4,000 in receipts). And while the cost may be impractical, I think there are several very practical design points which could easily be extended to other less- expensive, less-automated brewing systems. I purchased the IBM 80286 PC-AT, monitor and the ADIO (analog/digital input/output) board surplus for under $30. This, coupled with a $17 SSR (solid state relay), a $3 solid- state temperature sensor and a surplus five volt power supply, forms a simple, elegant and fully programmable RIMS controller. The computer controls four solenoid valves, two pumps, two electric heater elements and monitors two temperature sensors and three water/wort level indicators. An animated graphical user interface shows times, temperatures, flow rates, wort/water levels, ..., pumps "pump", water/wort "flows", flames "flicker", ... The state of the entire system is logged to a "batch" file once every minute. The web page also describes: an $80 gear-driven MaltMill- based grain mill with a 15 pound hopper; a 12 gallon temperature-controlled cylindriconical fermenter; and an eight keg, six faucet keg dispenser. Please take a few moments to check it out... Joe Return to table of contents
Date: Fri, 9 Jan 1998 14:03:25 -0500 From: "MMC Richard A. Kappler" <KAPPLERR at swos.navy.mil> Subject: newbie questions, vol 2 Thanks so much for the posts I have received so far, and for those hopefully still coming. I have a gazillion of these, but am trying not to flood the list. Also I find that, as you fine folk answer the questions I have already asked, you also inadvertantly answer some I was about to ask. So, on to vol 2. My querry about growing and mashing barley in vol 1 should have read growing and MALTING barley, sometimes the fingers get confused. I got several excellent arguements for switching immediately to all grain (not to revive a recent heated thread:-) and eventually intend to, but right now I am most concerned with refining technique and learning processes. I'm an engineer, I usually want to know how something works before I try to work it. 1. I used a cash Christmas gift to make a wort cooler, and the thing works great, 212 to 75F in 16 minutes vice a few hours. Doesn't the copper react with the wort though? I know that copper easily gives off ions and readily reacts with so many other compounds and substances, how does it react here? 2. I switched early to the 5 litre kegging system vice bottles, and absolutely love it. The one problem I had was having enough to fill 4 kegs and a couple bottles. When I bought my 8 gal pot to do full boils, I started making bigger batches (5 1/2 - 6 gal instead of 5 gal) and voila! the problem was solved. At the same time, upon recommendation of another homebrewer whom I don't remember, started straining my wort as I transfered it to the primary, removing most of the hop residue. I cracked the first keg using these two changes the other night and was very disappointed. I had brewed 'sea bass ale' from a recipe I have used frequently with nary a problem, but this batch turned out kinda, well, watery. Not as much body as it should have. Opinions? 3. One of the other lists I'm on is in a raging debate about fluid to use in air locks. One side says always use something like vodka and the other side says water. Opinions? 4. My brews typically ferment vigorously enough during the first few days to bubble up right through the airlock and make a mess. One brewer suggested I stop using the airlock at first and use a blowoff tube to another container. Sorta makes sense. He additionally said that when rapid fermentation has ceased and I'm no longer getting effluent from the blow off tube, I have reached "high krausen" and should immediately rack of to a secondary for better flavor. Up to now, I wait until the airlock stops bubbling, usually a week -ten days, then rack to secondary for about another week, prime and keg, age for at least a month and enjoy. I'm so confuzzled! thanks in advance, Rich Return to table of contents

Has anyone else (particularly you style officionados) tried the new Sam Adams Scotch Ale? I love the taste of it, and the alcohol level seems about right to me. Having never had a Scotch Ale before, though, I can't tell whether the taste is right. It does seem too highly carbonated for a beer that's supposed to have "very low carbonation." I love the beer, but I'm also interested in whether it's to style. Any comments? Thanks, Loren ========================================================================== # Loren D.

Date: Fri, 9 Jan 1998 15:01:46 EST From: KennyEddy <KennyEddy at aol.com> Subject: Newbie Questions Kent Cambell has some newbie questions. "This is my first post to this list, and you will surely discover that I am a neophyte. Now with that admitted and acknowledged, I will, with great trepidation, post a question that will surely show my ignorance." Welcome Kent! The only thing that would show ignorance is NOT asking questions. "I received a Homebrew Kit from my Daughter for Christmas, and a great book on the subject as well. It included a 3.5lb can of malt extract, 2 lbs of dried malt extract, a packet of Edme yeast with a 1999 expiration date, and some ?Fuggles? hops. I read up on how to do this procedure, sanitized everything as well as I could think with Clorox, rinsed well, boiled everything for 45 minutes, followed the instrucs on the Hops (steeped like tea in the last 15 minutes using a straining bag), cooled the wort to about 75 degrees F by using a..." I assume then if the instructions said to simply steep the hops for 15 minutes, the extract must be pre-hopped for bitterness. 15 minutes isn't long enough to get any significant bitterness from the hops (most brewers boil bittering hops at least 60 minutes). If the extract was indeed pre-hopped, then fine, but if not, you can expect a sweet product with little bitterness. "...sink bath around the pot (tap water was about 43 degrees, so got a quick cool down in my 14 qt. pot), and put it in the Carboy. Added store bought bottled distilled water to 5 gallons, and added the yeast which had been hydrated in a pint of boiled and cooled water, placed in a sterile half gallon container to which was added about 4 tablespoons of the canned malt extract mixed in a quart of 95 degree boiled and cooled water. That had been left to start for about one hour while the wort was prepared. " So far so good, sorta. Careful with the "store bought" water. A recent thread here indicated possibility of contamination, since not all bottled water is "sanitized" (some is UV samitized and some is packaged tap water, so who knows?). That said, I made many of my first beers topping off with straight tap water without infection, but YMMV. Also, the yeast package normally contains sufficient nutrients for starting the culture, so adding sugar/extract to the rehydration may not be necessary. Check the package to be sure. I don't suppose it hurts to add it though, especially if the package has no information or specifically instructs you to do so. "Placed the lid, and the airlock, and watched the thing pop at about 70 to 75 beats a minute for the first 36 hours, then slowly drop off to no activity in the air lock after about 48 to 60 hours. " Sounds good. Many first-time brewers experience very quick fermentations (often due to high ambient temperature), or no activity at all (often resulting from a poor lid seal; the CO2 escapes through the leak rather than the airlock). "BTW, the OG was 1.013 at about 75 degrees F. After 7 days, I took a sample from the carboy and tested the SG to see if this stuff was getting ready. To my absolute surprise, I got a SG reading of 1.013 at about 64 degrees F. Now I know that there is an adjustment for temperature, but it sure seems to me that virtually no fermentation has taken place. What is the deal? Can I save this batch by re pitching with new yeast? Why didn't the sugars..." With the amount of extract you specified, you should have had an OG (5 gal) of about 1.042. What probably happened is that you didn't mix the wort with the top-off water well -- the heavier wort sank to the bottom, and you took your hydromerter sample from the dilute liquid on top. This is a fairly common "mistake" that i can recall making once or twice till I figured it out. The fermentation activity would have mixed everything well, so that solves that problem. 1.013 is a reasonable finishing gravity for this OG, but give it a couple more days at least, just to be sure (and to prevent overcarbonation in the bottle). Your beer should be just fine. ***** Ken Schwartz El Paso, TX KennyEddy at aol.com http://members.aol.com/kennyeddy Return to table of contents
Date: Fri, 9 Jan 1998 14:19:22 -0700 From: "Schroeder, Curt" <cschroed at ball.com> Subject: Extreme Brewing With respect to High Altitude Brewing I'd like to share my vision of it as being part of a bigger class of brewing feats...."Extreme Brewing" Operation: Hypoxia is an example of "Extreme Brewing" which was a fun adventure, plus it can get your club publicity and helps promote homebrewing. IMO "Extreme Brewing" isn't constrianed to altitude, but could be brewing: on tall buildings, on the pitchers mound at Dodger Stadium, at the North Pole or like a club did in Arizona a few years back have a brew-a-thon to see how many batches could be brewed in 24 hours. The idea is a brewing activity that someone says "That's neat I wish I'd thought of that" I just love to hear about such adventures and encourage others to join in Extreme Brewing it's alot of fun. It all started with something as tame as brewing during a campout.

What a shame it's so denigrated. Corn is a wonderful flavor adjunct to our bag of tricks. The reason it is so denigrated is because the megabrewers use it to reduce the cost not to enhance or alter the flavor. Fact is, most of them do not even use corn. They use corn syrup which has been stripped of all flavor and contributes nothing but fermentable sugar. It's a bit like intraveneous drugs. There is no need to even use malt because no enzymes are required. The end product is fermented corn sugar not beer.

An hour or two is exactly what "intermittent duty" is not. This is definitely not an application for intermittent duty. That implies several minutes not hours. From: "C.W. Hudak" <cwhudak at gemini.adnc.com> Subject: Fixing my enamel pot "I've searched the archives but keep coming up with nada. I'm looking for a product to repair the chips in my enamel on steel brewpot. I quit selling EM is kettles because of the chipping from shipping damage. In trying to sell them at discount, I tried all sorts of things and have concluded that nothing exists that I would want in contact with my boiling or mashing wort. The heat resistance is easy but the potential liability from selling it is too great. There is a stainless charged epoxy that cures at around 400F that will then tollerate the flame under the pot but like I said, I would not use it on the inside. You can cure it just by holding it above a flame for a few minutes. I used the same kettle for 20 years and boiled maple syrup, fish and beer in it over the years. All I ever did was to rub a little Vaseline on the bare metal before putting it away and wiping it off when I wanted to use it again. There still not nothing else on market that can get one into real brewing for even twice the cost. From: michael rose <mrose at ucr.campus.mci.net> Subject: mass appeal beer, mixmasher " mixmasher comments: I'm in a slow process of building a rims system. If my understanding of rims is correct, then one drawback is the slow temperture rise. Wouldn't a person be able to turn on the mix masher, then fire up a 200,000 BTU burner under it? Nice try but you would have to churn so fast you couldn't keep it in the kettle. Scorching is a potential problem with both systems and probably more difficult to control with a flame. I suspect there is not much difference in allowable temperature rise rates of the two approaches. I don't have a good handle on the rates but it usually takes about 45 minutes to raise my mash from 155 to 175F without any concern for scorching. I could do it faster but then I would have to "worry" and we don't want to do that, do we? js - -- Visit our WEB pages: Beer Stuff.........http://ays.net/jsp Astronomy.......http://user.mc.net/arf ASTROPHOTO OF THE WEEK.....
