---------------------------------------------------------------------- Date: Mon, 9 Oct 1995 15:06:34 -0700 From: bbrowne at golder.com (Barry Browne) Subject: Commercial RIMS components Hi all, This message was sent before with no confirmation; here goes again. I've been interested in owning/building a RIMS ever since the '92 Special Issue of Zymurgy with Rodney's schematics. I'm no electrician/electronics type so I never got up the nerve to try soldering that puppy together. Anyway, I'm wondering if a company called Brewcraft, Ltd. out of Carrollton, TX is the answer for me and all other electronics-challenged RIMS-envious people. This company, blah blah, sells ready to go controllers/heaters/temperature probes based on Rodney's concept. You use your existing mash setup, buy the magnetic drive pump elsewhere (Grainger) and some plumbing hardware. Hook their stuff to all this and presto, a RIMS. The cost of Brewcraft's gear would be about $250 (for the heater, all controllers, and temperature probe). I am seriously considering buying Brewcraft's system but would like to know first if anyone out there has already done so, has comments about it, or knows of other similar commercially available equipment? Any and all responses are appreciated. There are a ton of you RIMS owners out there, and I want to become one too. FWIW, I already have the pump and recirculate my mashes. It's great. All I lack is what Brewcraft offers! Brewing on in Atlanta, GA Barry bbrowne at golder.com Return to table of contents
Date: Mon, 09 Oct 95 12:54:02 pst From: rbarnes at sdccd.cc.ca.us Subject: JOCKEY BOX SUMMARY Lots of questions today. I'm making the switch to kegging and all-grain at the same time. Regarding my post a couple of weeks ago about freezing copper coils in ice in a jockey box, I received private replies suggesting that the expansion of the ice would in fact crack either the cooler or the copper tubing. Also, the extremely cold coils might cause beer to freeze in the line during the initial dispensing. I think I might try to use the coils in the cooler (permanently installed), and insert bags of "blue ice" to maintain cold without the danger of breaking the cooler or the coils. The frozen coil problem might be more difficult. I might try to use 3/8" copper for the coils and use 3/8 pipe to 3/16" hose barb adapters to the beer lines. That would make it less likely for the frozen beer in the coil to stop the flow of beer (I would think). If anyone has any other ideas/comments/etc, please let me know. ********** In the latest Zymurgy special issue the author of one of the articles commented that there was still some debate in homebrewing circles over whether aluminum pots were acceptable for use in brewing. My understanding was that the aluminum would undesirably affect the beer. Anyone out there using aluminum? It's sure cheaper than stainless. ********** On the subject of pots, can I drill a hole in the side of an enameled steel pot to insert a drain fitting? Since this will almost certainly damage the coating, is there a way to repair the damage to avoid wort contact with steel? ********** Also, does anyone have comments on doing an overnight mash in a round Gott cooler? This would begin at ~9pm, 158 deg., sparge and boil the next morning. Does this have any drawbacks? Private e-mail is fine, I'll summarize. TIA- Randy Barnes, San Diego. Return to table of contents

Date: Mon, 9 Oct 1995 18:05:29 -0400 From: rich at lenihan.iii.net (Rich Lenihan) Subject: Dave Miller's book Dave Miller has recently produced an update to his "The Complete Handbook of Homebrewing". The new book is called "Dave Miller's Homebrewing Guide". The short review is that the new book is pretty damn good, although some might find it less technically "dense" than TCHoHB. It's still the best single reference source for homebrewers of all levels, IMO. The new text covers some topics that weren't covered in the first book, such as kegging and filtering, as well as most of the topics covered in the the first book. In fact, some sections of TCHoHB are repeated word for word in "Dave Miller's Homebrewing Guide". Is this book a must buy? Well, if you already own TCHoHB or both of Papazian's books ("The New Complete Joy of Homebrewing" and "Homebrewer's Companion"), maybe not. Otherwise the answer is an emphatic yes.

Date: Mon, 09 Oct 1995 19:08:13 -0400 (EDT) From: DANVATH at delphi.com Subject: Flat Beer! Fellow beer nuts, First time poster (yikes!): My latest finished batch, a doppel bock, turned out completely flat (3 out of 3 bottles). I have two theories as to why this happened, as I did two things for the first time with this batch. Any solid theories offered as to which is the culprit would be much appreciated. 1. Length of fermentation: I fermented in the primary for almost 3 weeks; fermentation didn't become active for 5 days (completely different screw up). I then transferred to a secondary where it stayed for another 3 weeks. Could the yeast have completely died in this long a time period? 2. Bottle sanitation error: My personal suspect. I use Grolsch bottles, and in following with an idea in the summer issue of Zymurgy, I sanitized my bottles by putting them in the dishwasher (no detergent) and washing and heat-drying them. Could/did this eff up the gaskets? They appear fine using the naked eye. The second isn't likely to happen again, since I'll be going to kegs very soon, but I'd like to know just the same.

The spent grains get thrown on the compost pile in the back yard, along with the spent hops and the grass clippings, shredded leaves, coffee grounds, eggshells, and chopped-up bits of leftover veggies. No meat, fats or animal matter of any kind! The compost pile loves it all. Makes fantastic topsoil. By all means, do it. Turn (aerate) the pile once a week or so with a rake, and it won't even smell.

The hbd-wisdom on this has been that the >yeast from the secondary is cleaner (i.e., more trub-free), but if you >use the oft-cited yeast washing techniques, the yeast from the primary >should be just fine. Again, I'd use a starter. I'm just speculating, >but it's possible that if you _are_ going to repitch into your next batch >without making a starter that the yeast from the primary would work better. I'll leave it to Dan to provide most of the details, but I'll just tell you what I've done and add one note of caution. Except for fruit beers and lagers, I use only a primary. I have had very good results simply racking finished beer off of the settled yeast (and, yes, trub) in the primary and pouring fresh, cooled wort on top. I have not tried to do this more than one generation and would probably limit it to two generations, personally. The one note of caution has to do with whether to use the yeast in the primary or secondary if, indeed, you have the choice. Every yeast population will have some mutations in it and possibly more than one strain. If you use the yeast from the secondary, you may be selecting for the poorly-flocculent yeasts, i.e. the percentage of slow flocculators is more likely to be increasing. *** Pat writes: >1/2 lb dark crystal, 6 oz black malt. 13.33 gal of sparge/mash >liquor was treated w/ 2T CaSO4 (poor choice, in retrospect. SHould >have used the carbonate...) and 1-3/4 t lactic acid. I don't know if you meant to write this or not, but what you've written sounds like CaSO4 (calcium sulphate, aka gypsum) and CaCO3 (calcium carbonate, aka chalk) are sort of interchangeable. They are most definately not. I just didn't want someone to read this and think: "hmmm... calcium lowers pH and my pH is too high, so I'll use CaCO3 to lower the pH..." This is absolutely wrong. While it's true that calcium (by way of reactions with the malt) does indeed lead to lower pH, but CO3 (carbonate) ions raise pH far more than Ca lowers it. Therefore, the net result is a rise in pH from CaCO3. Judging from the grain bill, unless your water is already very high in CO3, I would not have added anything to the sparge water, even the lactic acid. If, when taking runnings, you measure the pH of the runnings and it's beginning to climb above 5.6 or so, then I would add a little lactic acid to the sparge water. In my case, I've brewed batches with 100% pale malt and the pH of the final runnings has been below 5.5, so I know that I need not worry about pH. Knowing this, I can, if I wish, add all brewing salt additions at the beginning of the boil (to imitate the water of a particular style). In the case of dark beers, however, I might actually have too low a pH (thanks to the acidity of the dark grains) and I do check the pH of the mash and add CaSO4 to raise it if necessary (depending on the amount of dark malts). *** Also Pat writes: >But the >question remains: Does Wyeast 2206 require particularly low >fermentation temperatures to do a clean job [referring to DMS >in the finished beer]??? Actually, I believe that a higher fermentation temperature would decrease DMS in the beer. Although I have not read it anywhere, I have long theorized that part of the reason that ales have less DMS than lagers is related to the fact that CO2 scrubs out the DMS that is created during the boil and chilling. Therefore, it would make sense to me that a more vigorous evolution of CO2 would scrub more DMS from the beer. Comments? Al.

Date: Mon, 9 Oct 95 21:32 PDT From: robtrish at mindlink.bc.ca (Rob Lauriston) Subject: lemon balm, hop-growing and beer styles Cher collective citizens of BeerBorg, As harvest is upon us, I contemplate what I should reap and what I should compost. Has anyone ever brewed with lemon balm? I think that I would probably try dry-balming. 'Lemon balm' seems to be something from a mint type of plant. When you rub the leaves, you get a lemon-furniture-polish sort of smell, less pungent than citronella. The Saxer Lemon Lager, or whatever it was from around Portland OR always struck me as gimicky and wimpy, but that's from the point of view of someone who has made the IBU pilgrimage Portland, to the hop heaven, lupulin loveland, humulone homecoming... I can still see trying a lemon balm ale. Such potential for puns: even the explosives squad couldn't stop the Lemon Balm from detonating. Lemons everywhere. Join the meringues. As for other crops: My hops from an unknown cultivar are still green and do not show any sign of browning or over-ripening that I can tell. Meanwhile, my bines from Mt. Hood and Willamette rhizomes have let the cones go brown, the leaves go yellow, and are generally preparing for Hallowe'en. I'm at 50'N latitude, so the photo-periodic response of the hop is at an extreme here. Is that why this is the northern extreme for hop cultivation? On the subject of hops, I was told that the hops in the lowermainland of B.C. are being grown on low trellises. I noticed that some hops I had on a three foot fence accepted horizontal training, but in their exertion upwards, they produced more cone-bearing side-shoots. Is this recognized as a way to increase hop yield, or at least simplify wirework? Some wild hops I picked seemed quite mild. Some I allowed to brown past oxidation and they produced an odour that made me think of cat pee. That reminded me of the comment of an English brewmaster dismissing a beer "made with those catty North American hops". At first I thought it was Imperial snobbery, but now I wonder more and more. The role of wild N.A. cultivars in creating our modern hops. All of this is spurred by reading Don Van Valkenburg. :) Wanna crank up the style thread again? Beer is especially ephemeral. How can there be any significant historical depth to the concept of beer styles when 1) the hops they had aren't available anymore and visa versa, when 2) malting barleys and malting methods have changed so much that malt flavours are likely significantly different, when 3) modern yeast strains are not only pure, but tend towards those which do not produce distinctive fermentation character, and 4) water and sanitation are likely to be controlled much more in a modern brewery? I've heard the anecdotes of the eighty-year-old who is offered a taste of a modern brew and proclaims it to be *exactly* like the porter, pils or pale ale they remember from their youth. I find these stories very unconvincing. Please do not be provoked by any of my comments unless you enjoy provocative. - Rob Lauriston <robtrish at mindlink.bc.ca> Return to table of contents
Date: Mon, 9 Oct 95 23:35 CDT From: pgravel at mcs.com (Philip Gravel) Subject: Mash agigation ===> Kirk R Fleming discuss extraction effiency and mash agigation >With the exception of the lowest extraction number I've ever gotten >(using a batch sparge to save time), my records indicate that the only >difference between the very low yields and the high yields is the >stirring of the mash (or the gross disturbing of the grain bed surface). >Again, I'm finding about 20% difference. This observation doesn't surprise me. When I was doing lab work, we always agigated chemical reactions either through boiling or reflux or stirring with a magnetic stirrer or overhead stirrer. The agigation ensures more uniform distribution of reactants (starch) and catalyst (enzymes). - -- Phil _____________________________________________________________ Philip Gravel Lisle, Illinois pgravel at mcs.net Return to table of contents

My feet have yet to touch the ground. Like Norm said, little ol' Cottonwood (formerly Tumbleweed) came home with a medal from the GABF!! For the smallest brewery in the competition to come home with a medal from as big a deal as the GABF is a fact I *still* find hard to believe. But I assure you I'm having a helluva good time coming to grips with it! I could go on and on, believe me, but the most important thing I want to say to this forum is THANKS I have loved and depended on the HBD from the first digest I received over 5 years ago. As we all know, the HBD is the single most important repository and brainfund of brewing information in the world. If you need to know an answer to your brewing question, it can be found in the HBD archives. We should all be proud of the quality of information that passes here. I know I'm personally honored to be a part of such a great bunch of folks. Ever since the Tumbleweed/Cottonwood gig literally fell into my lap, I haven't had the chance or time to share and post as much as I once did but I read it every day and depend on the brother/sisterhood to inform me of its findings, experiments, and research as I try to hold the brewery together. I've used what I've learned here to conquer the inevitable headaches and problems that come from running a commercial operation even if I don't always get back to tell you how much you've helped. If it weren't for what I've learned from this forum, I dare say the Cottonwood experiment would be a dim and unpleasant memory in my mind. Instead, I'm proud to say it's brought me one of the greatest joys of my life. I hereby dedicate the ribbon that held the medal around my long, skinny neck all day Saturday to the HBD and invite you all to come see and touch it at the brewery! It's as much yours as mine. I know in my heart we never could have done it without you. I still don't think of Cottonwood as a commercial brewery and I don't think of myself as a commercial brewer. I'm a homebrewer brewing in a big homebrewery. Always have been. Always will be. Thanks again.

Here's my theory: Drunk drivers are running over healthy 60+ year olds who are out jogging. Moderate drinkers are only at risk while walking home from the pub. -or- teatottlers are so sick their doctors have made them stop drinking. Of course, their mortality is highest. Next up are those only sick enough to have to cut back to moderate drinking. Sorry, I couldn't let this one go by. jayw Return to table of contents

I don't compost my grains. I spread them on the top of my wife's flower beds. A lot cheaper than pine bark mulch, and just as attractive.

I once wondered if it could replace the stirring I was doing along with the recirc, so, on a batch of my 'Up The Creek With A Paddle' Oatmeal Stout, I did just that. Nothing. My extraction for that batch was _dismal_ (the beer was GREAT - possibly one of my best stouts, the extraction was dismal) at around 18 pt*gal/lb. My normal rate is on the order of 31. Just another data point. >And a gripe, related to the above... *** GRIPE MODE ON How does an extremely technical group, as most of us homebrewers tend to be, botch a units designation so badly? I'm talking about Points-gallons-per-pound. How do we justify showing this as p/g/p?

Any data about efficiencies at other temps for 67% mash thickness? Does a "thicker" mash allow beta amylase to survive to higher temperatures? When using "infusion" techniques for the 40-60-70 mash I generally have a "thick" mash at "60"C in order to minimize the quantity of "infusion" water required to raise the temp to 70C and keep the mash from becoming _too_ thin at the 70C rest. I shoot for ~1.5 qt/# at 70C. >Regarding starch gelatinization, "Malting and Brewing Science", pp >292-293 states, "In mashing it is the liquefying action of >alpha-amylase that is chiefly responsible for the dissolution of the >starch granules, which only begin to gelatinize at about 65C(149F), >but which slowly swell at lower temperatures [55-60C,(130-140F)] and >become progressively more susceptible to enzyme degradation". Perhaps the optimal temp range for beta amylase activity _is_ 60C, but unless the starch is gelatinized,beta-degradation will be slow. >Dave Miller in "HBofHB" chapter in mashing states the optimal >beta-amylase temp as 140F(60C), but notes that a gelatinization temp >of 149F(65C) prevents complete conversion at this temperature. ditto >George Fix in 'Principles of Brewing Science', pp 95 states, "One rest >is typically in the range of 55 to 60C, which is optimal for amylase >activity.

With these minor discrepancies (evolution in thought) in the open literature, the question arises: What sort of profile do traditional European breweries use? >My personal experiences with 60C rests agree with George Fix's quote >above.

I guess I don't see any agreement that 60C >is at the low end of the active range for Beta-amylase, it appears to >be in the maximal activity range according to several reputable >sources. I think the underlying problem is _not_ that 60C isn't optimal for beta amylase activity, but that beta-degradation is a slow process at 60C since the starch has not yet been gelatinized (in an "infusion" mash). This is one advantage of decoction mashing over "infusion," IMHO. If decoctions are used to raise the temp to 60C there will be a considerable amount of gelatinized starch and dextrins present. I know from experience that after 30 min at 60C the mash liquor is "sweet" in an infusion mash, but it is still quite hazy, whereas at 63-65C it is quite clear after the same amount of time, and produces a lower FG beer(30 min at 60,63-5C; 30 min at 70C). Perhaps there is some alpha amylase activity in the 63-65C range as well. TTFN --<- at Russ Brodeur (r-brodeur at ds.mc.ti.com) Franklin, MA Return to table of contents
Date: Tue, 10 Oct 1995 13:55:51 -0500 From: Russell Mast <rmast at fnbc.com> Subject: Et Cetera Lots of talk about repitching yeast. Yesterday, I brewed a 5 gallon batch of "leftover ale". While it was boiling, I racked a batch of something else into a secondary. It was in the primary for about 9 days or so. The original culture was a Wyeast Scottish ale yast, not sure what number. Rather than bottle the yeast or wash the primary, I just poured stright from my cooling apparatus onto the yeast. I was extra careful to aerate mightily. This thing took off like a rocket. High kreuzen within 6 hours. (Maybe less, I had to go out for awhile, came back and whoosh, it was blowing off like a maniac.) I've heard people swear up and down that pumpkin has almost no flavor and all the flavor in a pumpkin pie is from the spices. Hogwash, I say, but the spices are probably a large part of it. Someone in private e-mail a couple of Novembers ago said that you should toast or bake the pumpkin first. I assume canned pumpkin has been through this already. This same fella said he mashes it, doesn't have much problem with sparging, and only uses the outer hull part, not the slimy meat inside. May try it this year myself. I'm pretty sure that treacle is made very differently than molasses, like from a different plant and all. That being said, it supposedly tastes very similar. Who knows? I've had good results with 1/2 cup to 1 cup blackstrap molasses in 5 gallon batches. (1 cup is on the strong side...) I've also had good, but decidedly different results, with 1-2 lbs. of Sucanat, a natural unrefined cane sugar product thing stuff. (Look in health food stores.) Kids and beer - it wouldn't surprise me if local jerks reading HBD (like over-zealous county sheriffs or church-lady busybodies) report someone for feeding beer to their kids. Legal or not, most child-abuse laws are worded very openly and these are odd times we live in. I'd be careful what you post. As Ken Willing pointed out, the study he cited was not perfect and should be taken with a grain of malt. Still - I'm not taking any chances. I'll have a couple beers today, just in case. :-) -R Return to table of contents

Date: Tue, 10 Oct 95 14:30:36 CDT From: korz at pubs.ih.att.com (Algis R Korzonas) Subject: Beta-amylase at 140F (60C) Steve, for some reason, blasts me for saying: >No. The rest at 60C (140F) is at the very low end of the active range >of beta amylase and is at the high end of protease range.

In case you didn't notice, there are quite a few contridictions in your quotes. Frankly, I don't know why you have to jump on my words like this. I was already going to address this issue after Jim Busch's much more polite post. What I should have said is that 60C (140F) is at the lower end of the *practical* range for beta amylase. If you'll recall the posts regarding that extra package of enzymes in some Pilsner kits or those on the subject of adding amylase for stuck ferments, back then it was posted by several brewers that while these enzymes are most active in the mid-to-high 140's (F), they do break dextrins down to fermentables even at room temperature... it just takes days. My *point* was that at 140F/60C, while I did say that there is some saccharification (I guess that I shouldn't have said "*very little*"), it is a very active temperature for protease. If not for the action of protease, then why mash at 140F/60C? Why not mash at 149F/65C? At this temperature, beta amylase activity is higher AND gelatinization is occurring too. The difficulty in talking about enzymes and optimal temperatures is that for every enzyme there are two factors: 1) the activity of the enzyme and 2) the denaturing of the enzyme. Let's take protease for example. Most books say that it's range is 122F/50C to 140F/60C. It's activity at 122F is quite a bit lower than it's activity at 140F. All throughout this range, protease is also denaturing. The higher the temperature, the faster the enzyme denatures (becomes useless). So, while there might be even faster activity at 145F/63F, it will denature faster than it is practical for use at this temperature. In my own typical mash schedule, I use a 15 minute rest at 140F/60C followed by a boost to 158F/70C for an hour (via an infusion of boiling water, incidentally). I get a rather dextrinous wort from this schedule and it also helps me handle proteins quite well. It has nowhere near the fermentability of a two hour mash at 149F/65C. I admit that my initial post was poorly worded and that my *point* (see above) seems to have been missed, at least by some readers. Nonetheless, this is no reason for dragging out the textbooks and copying out paragraphs, as if we wouldn't believe you if you simply wrote that they said otherwise. Al.

Date: 10 Oct 1995 22:01:22 GMT From: "BATLAN -D1FKV0W" <D1FKV0W at BATLAN.BELL-ATL.COM> Subject: LONGER LIFE AND BEER CONSUMPTION This is my first posting, as I am a new homebrewer. I did my first solo batch on Labor Day (I had helped a friend extract brew previously), and have an orange blossom mead happily fermenting since the equinox. WRT Herb B. Tuten's <HERB at zeus.co.forsyth.nc.us> post on bottling techniques, I was very happy with the bottling bucket that came with my starter kit. It served as a sanitizer for my hoses, caps, etc., then I used the spigot to fill the bottles with the slightly used bleach solution. When I was ready to bottle my beer, I inverted each bottle over my jet bottle washer, shook it out and filled from the bottling bucket. I didn't bother drying because I figured the little bit of residual water wouldn't dilute the beer enough to notice. I thought this worked well, even though I was bottling alone. With a helper, it would have gone even better. Now, a question. I have heard a lot about contact times and strengths for sanitization, but wonder whence this information ultimately comes? I have seen recommendations to use 1oz bleach/gallon of water for an hour. My sister, whose degree is in Food Industry and who works with sanitization of commercial food processing containers and equipment on a daily basis, says that at 200ppm (~=1 oz of household bleach per 2 gallons water) the contact time for "commercial sterility" (that is apparently the FI term) is a mere 90 seconds! What gives? Any authoritative references to suggest? ====== WRT Ken Willing's <kwilling at laurel.ocs.mq.edu.au> post: >If you had "up to 2" standard drinks a day ("one standard drink" = approx. >10 ounces of beer, or the alcohol equivalent in wine or spirits), you were >10% more likely to be alive at the end of the period than if you had none. > >If you had "2 to 3" standard drinks a day, you were 30% more likely to be >alive at the end of the period than if you had none. > >If you had "3 or more" standard drinks a day, you were 60% more likely to >be alive at the end of the period than if you had none. By historical standards, 1 1/2 oz of alcohol/day (I assume that even Aussie beer tops out around 5%) is not a lot. Pulling an envelope out of the recycling and doing a quick calculation, I compute that as (at uttermost) .083% blood alcohol for a 150-lb adult. Still legal to drive in PA. Of course, in America, when we don't do something, we *really* don't do it, so three drinks a day is considered by many people as heavy drinking. Likely explanations (none original to me): 1) Moderate consumption of alcohol assists in achieving a healthy relaxation. Of course, *forcing* an LDS to consume alcoholic beverages would be anything but relaxing for either party! 2) Alcohol consumption is correlated with other healthy behaviors, such as socializing, owning pets, etc., especially among older people. 3) People with diseases that are likely to kill them in five years or so are often prohibited from drink by their doctors; for instance, many medications have adverse reactions when combined with alcohol. This may or may not have been corrected for, and the correction may or may not be the proper one. 4) People who lie about their alcohol consumption are more likely to die early. ;-) (OK, this one *is* original to me).
