---------------------------------------------------------------------- Date: 12 Apr 1993 11:34:07 -0600 (CST) From: SWEENERB at memstvx1.memst.edu Subject: kegging using a beer chiller I have a question for you keggers out there. I have the opportunity to buy several used Cornelius (sic) kegs and connections for what seems like a reasonable price ($10/keg with connections). I do not however have an extra fridge and probably won't for the near future. Is it possible to use these kegs by connecting up a beer chiller like the one displayed in the recent Gadgets issue of zymurgy--basically a copper tube running through an ice bucket through which the beer flows? I was wondering, beyond the obvious pain of having to fill the bucket with ice periodically, what are the disadvantages of this system? Any advice would be appreciated.

Are you sure the yeast were really roused into fermenting? I offer the theory that the 1 glub/min was due purely to escaping CO2 and not fermentation, so the swirling just released a lot more gas (as evidenced by increased bubbling). After this had died down the release rate would decrease. The lower temperatures that you'd been fermenting at would allow more CO2 to dissolve which would explain why it took longer to escape. I'm convinced I'm right, but feel free to flame away at my ignorance. Peter Return to table of contents
Date: Mon, 12 Apr 93 13:08 CDT From: korz at iepubj.att.com Subject: Re: Blowoff (fusels, etc.) Joseph writes: >Finally, fusel alcohols are quite soluble in alcohol, and can not >be removed by blowoff. The unpleasant substances in blowoff residue >are tannins, unisomerized hop resins, etc. They are largely insoluble, >even in a weak alcohol solution, and are not going to be a primary >source of bitterness or astringency in your beer once it has cleared. First of all, thanks for the very informative post -- I'd like to sit down with a few Pale Ales and do some palate training together -- how about Portland, say, late July? I've had very little chemistry, so I can't disagree with you regarding what actually gets blown-off, but I have some beers done in split batches blowoff versus non-blowoff and the difference was stunning. I can't begin to explain it in chemical terms, but there definately was a big difference in bitterness and astringency between the two sub-batches. Perhaps its not the fusel alcohols or the tannins or the unisomerized hop resins, but the difference in flavor was unmistakable. Over the weekend, I bottled an Imperial Stout which I fermented using the blowoff method. I would like to suggest an additional effect of using the blowoff method (although it seems quite negative and does little to reinforce my continued support of this method) -- loss of head retention. It's not so much that I've noticed a reduction in head retention with the blowoff-method beers, rather that the brown foam that oozed out of the blowoff vessel and onto the floor during high kraeusen, HAD DRIED AND STILL RETAINED IT'S SHAPE TWO WEEKS AFTER IT HAD FORMED! Do you follow me on this one? The blowoff filled the gallon jug which was supposed to catch it all and foamed out of the top of it, onto the floor. When this happened, I cleaned up most of it but some was back between the carboy and jug. This weekend, that stuff was solid and looked like brown styrofoam. Could this be some of the small proteins and big dextrins that give you good head retention? Could I have lost something useful, besides the quart and a half of beer? Or are the proteins and dextrins distributed throughout the beer and I'll just be able to do parlor tricks with this beer? [By the way, OG 1120, FG 1050 (approximately 9.2% Alcohol by volume) -- more attenuative yeast needed next time (very sweet).] Al. Return to table of contents

I'm an extract brewer, interested in all grain. The logistics of all grain (bigger pot, chiller, heating up 6 gallons of wort) have so far kept me from trying all grain. My brother-in-law (Greg) told me of his method this weekend and I'm posting this note to see if others have used it (and with what success). FYI, Greg has been brewing for several years and makes a good brew. OK, this is what Greg does which I found interesting. 1) Prepare mash in a pot with 'warm' water. 2) Put pot with mash into the oven, with the oven set to "warm". Leave it for an hour or two. (As Greg says 'no fuss, no muss'.) 3) Transfer mash to lauter tun. 4) Run 2 or 3 gallons of hot (170F) water into lauter to sparge. 5) Boil the wort (2-3 gallons) with hops. 6) Run 2-3 gallons of cold (tap) water into lauter to complete sparge. 7) Combine cold sparge/wort with boiled wort to make a complete batch AND to obtain cold break. This is his tried and true technique. He does not seem to have any contamination problems and as I have said, makes a good brew. Has anyone else used this partial boil, cold sparge, method?

While we here in New England see most of Sierra Ne- vada's fine products, for some reason two of their most interesting brews--the Maibock and the Bigfoot Ale-- aren't distributed here. Rumor has it, though, that they can be found in New Jersey, where I'm going in a few weeks to visit the in-laws. Can some Garden State reader of the Digest help me find them? I'll be getting on the Parkway at its northern terminus, right off the Tappan Zee, and driving it to south of Asbury Park. While my wife does like beer and is willing to put up with my interest in it, she doesn't have much patience for driving around aimlessly for very long, so I'd like to know of a store within a few minute's drive off the Parkway.

Date: Mon, 12 Apr 1993 21:24:49 -0400 (EDT) From: "Spencer W. Thomas" <Spencer.W.Thomas at med.umich.edu> Subject: Oops, bottle bombs??? I recently made a batch of wheat ale (Wit style) with a new yeast (supposed to be Hoegaarden strain). It started slow, but built up a big krauesen -- needed a blow-off tube for a week. Eventually it slowed, and 3 weeks later was putting out one bubble every 45 seconds, roughly. I figured it was time to bottle. Racked onto priming solution in a second carboy, and took S.G. 1.020... Hmm... Initial gravity 1.040... Hmm... Tastes ok... Not too sweet... Late night decision -- let's go for it. Bottled 2 cases. But then, I got worried. Talked to the friend who gave me the yeast. He didn't think it should stop so soon. Talked to another friend who had used the same yeast in a similar recipe. His went from 1.047 to 1.014. Hmm.... One major difference: my fermenter was in the cellar, at 56F, his was at 65F. Maybe this yeast doesn't like to be cold. Hmm... Ok, brought a bottle up from the cellar, shook it well, and fitted a fermentation lock. Couple days later, it's still going nicely. Hmm... Haven't taken an S.G. on this one yet, but it's looking like I blew it, and mistook a stuck fermentation for a finished fermentation. Now, I could chill the he** out of these bottles, and drink them up quickly, or I could try to relieve the pressure, or something. I'm not wild about pouring 2 cases of bottles back into a carboy (not to mention the inevitable aeration that would take place). I could see lifting and resealing (or replacing) the caps a couple of times. Or, I could chill the h*** out of it... Any advice? And, a hard scientific question: How many volumes of CO2 should I expect to get from a .001 drop in S.G.? Haul out the old envelope. Let's say that 3/4c corn sugar produces 2 volumes in 5 gal. That's 3/8 lb, at 40pts/lb/gal is 12/5 pts, so maybe I get 1 volume/gravity pt. So, if my test bottle keeps going down to 1.014, I'm going to get about 6 volumes! Bottle bombs for sure! But I could relieve the pressure a couple of times (if I do it at the right time!) and be ok, ... maybe ... Hmm.... =Spencer W.

I finally got around to looking for a 5 gal. carboy for a secondary and went to talk to my lab professor in the Chem E. department and guess what!! I got two 5 gallon carboys for $5. They were really dusty, but didnt smell like any noxious chemicals and weren't stained or anything. So, if you have a university you might want to check out the Chem E or Ag department to see if there are any old carboys around. BTW, one of the carboys is made of the old blue tinted glass and has the date 1932 stamped on the bottom!! I wonder if it's worth any money :-) Andy Return to table of contents

Date: 13 Apr 1993 10:24:36 -0300 From: Ed Hitchcock <ECH at ac.dal.ca> Subject: Wyeast Bohemian Lager yeast In an effort to make a Pilsner Urquell type lager, I used the Wyeast 2124, Bohemian Lager, as per recommendations on the net. A friend also used the same strain, and his beer came out, well, bad. I chalked it up to an infection or some such. But I tasted my lager yesterday (still in secondary, clearing slowly) and it tastets the same as his. Quite phenolic, a little estery, and lots of dry sulfury compounds. In short, it tastes like a mediocre Lambik. Admitedly there was a long lag time when I pitched the yeast (the pack hadn't quite swelled up, so it took about 3 days to get going). But the fact that I have not once had an infection since my first batch (followed the instructions on the can on that one), and that my friend has yet to have an infection, and both of us brew with 2124 and it tastes the same in each case seems to indicate that either 2124 isn't the yeast for making PU clones, or these packs were contaminated.

Anybody out there a member or > ex-member? Any and all comments will be appreciated. Scott, I've been a member of CAMRA for several years, mostly just to get the Good Beer Guide, but it also to help me in planning my trips to the UK. Their newsletter is good, and keeps me up-to-date on the dates and locations of Beer Festivals (to which CAMRA members are admitted free). If you travel to the UK often, CAMRA membership is well worth the price. While passing through an area, I can always rely on the pubs in the Guide to give good service, beer, and usually food. Keep in mind, however, that omission from the GBG does not imply a lower- quality pub. Indeed, many of my favorites are not listed. If you're in a town for more than a day, don't depend solely on the GBG - ask the locals about good pubs. Curt Harpold curt.harpold at east.sun.com Return to table of contents
Date: Tue, 13 Apr 93 08:53:02 -0500 From: gjfix at utamat.uta.edu (George J Fix) Subject: Screen Tests I received some e-mail from people asking for more detail regarding the sieving tests to evaluate grain milling. Apparently there are a few people who would like to build their own apparatus for doing this. I think this would be a terrific project for a homebrew club. The best model that comes to mind for getting ideas for designing a screen sieving device is the Pfungstadt plansifter described by DeClerck (p.321, Vol.2). Here the screens are in parallel, and placed in order of decreasing screen width. One will note that the device is not large. Indeed, it is traditional to do tests on only 100 gram samples. This of course raises the practical problem of avoiding sampling errors. The usual rules regarding small sample sizes apply. It is often a good idea to run several tests on samples taken from a particular crush to make sure the measured results are robust. There is strong agitation during sieving. DeClerck reports that the screens on the Pfungstadt plansifter are rotated ~300 times per minute for 5 minutes. It has been my experience that this is ***very*** important. As Jim noted in his post, the MM will leave over half of the kernels in a state where they look as if they were not crushed. Without the proper agitation they will be artificially captured on the coarser screens. This will result in very large errors (up to a factor of 2) in the measured results. With proper agitation, on the other hand, they will fall apart just as they do when we rub them in our hands. The major application of a sieving device is in the determination of the proper roller spacing. This can be used not only for a MM, but for any other mill, and indeed even a Corona. It has been my experience that the best spacing will vary with the type of malt that is to be milled. I hope that anyone who who starts a project along these lines will keep me abreast of their progress. I bet the whole affair turns out to be a lot of fun. George Fix Return to table of contents

In my attempt to calculate how much hops to use as well as body characteristics, I need to know how much fermentable sugars are in a unit weight of honey. I realize that there is no simple answer to this, given the fact that honeys can vary greatly depending on the flower and the regional conditions. However, that caveat being stated, any insight would be greatly appreciated. Andy A Bitch's Brewery Return to table of contents
Date: Tue, 13 Apr 93 10:31:30 EDT From: cjh at diaspar.HQ.Ileaf.COM (Chip Hitchcock) Subject: re measuring alpha acids with pH meter One problem with the assumptions and one with the results: Tannic "astringency" doesn't have much to do with pH. Examples: colas are in the range of pH 2-3 (\very/ rough, but certainly more acid than your tea---the acid in colas is as much a problem for your teeth as the sugar) and nobody calls them astringent; typical vinegar at 5% acetic acid is something like pH 3 (it's been a \long/ time since I had to work from Kdiss to pH), ditto. There are many organic acids which have a very modest effect on the pH of water. I don't know the mechanism of astringency but I would guess it's some other reaction completely; try tanning leather with a random acid and see where it doesn't get you.... pH is a log10 measurement. .3 decrease in pH is 2x acidity, .47 is 3x, .6 is 4x, .7 is 5x. According to bc (UNIX calculator program), e ^ ( .4 * ln(10) ) is 2.5, so your result actually doesn't agree with expectation--- EXCEPT that weak acids don't affect pH in proportion to their concentration. Crudely put, the acid has to break into H+ and (remainder)-, to change the pH; this is a balancing act in which the more acid you have, the less of it actually dissociates. What's the average Kdiss for hop acids? Damfino---George Fix or Steve Stroud might have numbers. I also don't know how "utilization" (amount of acid extracted) varies with acid content---I would expect the % utilization to be lower for the same mass of high-alpha hops compared to low-alpha (since you're trying to make a more concentrated solution) but have no figures on \how/ \much/ of a difference this is. To eliminate this factor you might need a Soxhlet (sp?) extractor, which is fun to watch but not cheap. Return to table of contents
Date: Tue, 13 Apr 93 07:57:05 pdt From: Ted Manahan <tedm at hpcvcbp.cv.hp.com> Subject: Oregon Homebrew Festival Full-Name: Ted Manahan ANNOUNCING THE ELEVENTH ANNUAL OREGON HOMEBREW COMPETITION AND FESTIVAL On Saturday, May 8, 1993 at 12 noon. Benton County Fairgrounds - 110 SW 53rd Street, Corvallis, Oregon. The Capitol Brewers, Cascade Brewers Society, Heart of the Valley Homebrewers, Mary's Peak Lagers, and the Oregon Brew Crew invite you to participate in the ELEVENTH annual homebrew competition and festival, the longest-running event of its kind in Oregon. The focus of the event will be a judging of homebrewed beer sanctioned by the American Homebrewer's Association (AHA). In addition, the Club will host a festival to promote awareness and knowledge of various beer styles, provide opportunities to share information about the homebrewing craft, and encourage interaction of homebrewers in a social atmosphere. ENTRY REQUIREMENTS FOR THE COMPETITION: Anyone 21 years of age or older may enter. All entries must be personally homemade by the entrant. No entrant can enter more than two entries in any one category. Entries must be registered for judging by 11 AM on Saturday May 8, 1993. Festival organizers will not assure registration or judging of entries received after this time. To help avoid a log jam of registrations the morning of the competition, entrants are encouraged to send or bring their entries to: Oregon Homebrew Competition and Festival, c/o Freshops, 36180 Kings Valley Highway, Philomath, OR 97370 by 5 PM Friday, May 7th for entry registration. All reasonable efforts will be made to transport, store, and serve each entry in the best possible manner. Entries that are mailed should be shipped via UPS as non-perishable food in appropriate protective packaging. As shipping may resuspend sedimented material, shipped entries should arrive with sufficient time for settling to allow the best appearance. Three bottles of at least 10 fluid ounces each are required for judging (one each for first round judging, potential second round judging, and potential best of show). Each entry (not bottle) must be accompanied by a sheet of paper specifying the following information: Brewer's name and address, category to be judged in (note: brewers should specify style within category to assist judges in evaluation; e.g. Light Lager - Continental Pilsner), recipe, and a $5.00 entry fee (checks must be made payable to Ted Manahan, _not_ Heart of the Valley Homebrewers; the entry fee is used to cover expenses for hall rental and ribbons). Efforts will be made to allow entrants at the festival to reclaim unused entries and empties; however, festival organizers makes no guarantees in this regard. Qualified judging of all entries is the primary goal of the event. Three judges will evaluate and score each entry using the American Homebrewer's Association (AHA) 50 point system. The average of the three scores will rank each entry in its category. The Master of Ceremonies or other qualified person will review elements of beer categories and styles with each panel prior to judging. The Best of Show will be determined by the best average score in a second judging of the highest average scoring entry in each category. A club competition will also result form the outcome of the judging. Brewers associated with any homebrewing club will receive points for their winning entries credited toward a club total. Club members should include their club name on their entry form. Points scored in this competition count toward NORTHWEST Homebrewer of the Year. The descriptions and standards used by the AHA at the National Homebrew Festival and Competition will be used in judging. Judging will be conducted in a controlled environment (separate room) away from the hubris of the festival. Entries will be received for judging in the seven following categories: 1) Light Lager (includes American and Continental styles) 2) Dark Lager (includes bock) 3) Stout and Porter 4) Light / Pale Ale (includes IPA) 5) Dark Ale (includes Brown Ale) 6) Specialty (includes wheat, fruit/herb beers, steam beer) 7) Strong Beer (includes dopplebocks, barleywines, and imperial stouts) Festival organizers reserves the right to judge an entry in an alternate category if, after registration is completed, it is found to be entered in a category having fewer than four entries. Ribbons and prizes will be awarded to First and Second place in each category as well as for Best of Show. We are looking forward to a highly enjoyable festival with a relaxing atmosphere, several displays, food concessions, music, a raffle and the opportunity to interact with masters and luminaries of the brewing craft. Judging and award presentations should be completed by 5 PM. Any questions regarding the festival can be directed to Ted Manahan at 503/926-6228, internet address tedm at hp-pcd.cv.hp.com - ------------------------ CUT HERE --------------------------- ENTRY FORM Entrants must complete one form for each entry.

The BBS is called Macsimizing BBS and runs on First Class software... you can either call in via text comm packages, or via the graphical interface that is available on both my BBS and info-mac for download. Also, I keep on seeing the (presumably) magazine Zymurgy being referred to..... could someone tell me how to obtain it? is it available on some news stands?

Simply put: The more cold water you >run through the chiller the cooler your wort will get, the faster you >do it, the faster it will get cool.

This isn't really right...A larger colder surface will cool faster because of more surface area and with a larger tube diameter you would want a high flow rate so that there would be turbulent flow instead of laminar( If it was laminar flow, there would be a warm boundary layer of water near the walls of the coil and the water towards the middle would not be doing any cooling). However, I think you would want the exiting water to be warmer for a given length of tubing. The amount of heat removed from the wort should be: (delta q) = m*Cp*(delta T) where m=mass flow rate of water Cp=heat capacity (dealta T)=temperature difference=Tout-Tin So, if the flow rate increases, the heat removed increases, and if the temperature difference increases, the heat removed increases. (I'm sure there is a bit more analysis of this that can be done...It's be a couple years since I had heat transfer and I didn't like that class anyway:-) Andy Return to table of contents

All are bluish-grey, flat and layered. Why not add some English rocks to your collection? I buy large quantities of Hugh Baird malt, and have noticed similar looking rocks in my grain. I usually discover them when the handle of my mill suddenly ceases to turn, so they're a little chipped around the edges and are therefore probably not museum quality.

My question is this - in order to achieve the same carbonation as using 3/4 cup corn sugar I need to calculate the Degrees of Extract available in the corn sugar. Then, based on the SG of the wort for krauseningadd enough to create the same Degrees of Extract. Is the above statement correct. MASHING What is the proper mash temperature during sparging?? I would assume it to be very close to mashout temp (170deg F). I have noticed that the temperature of my runoff during sparging has been 150F. I typically heat my sparge water to 170-175 about fifteen minutes before I start my sparging procedure. Is this reducing my YIELD???????? Next time I will heat the sparge water to the proper temp. immediately prior to using it. Tom Stolfi wauts at cwemail.ceco.com Waukegan, IL Return to table of contents

Jack, I heartily applaud your experiments. I did have some comments on your interpretation that seemed worth posting, but I think your efforts were worth- while.

Boiled tap water reaches stability > within a few seconds. I presume it has something to do with > dissolved gas. Or another explanation involves the cantankerous nature of pH meters. In general, they will respond much more rapidly if they are used to measure similar samples consecutively. For example, if you calibrate the meter using the commercial buffers, then put the electrode in a solution with comparatively little dissolved solids (like water) it may take the electrode a while to settle down in its new environment. Once stabilized, the next water sample you measure should equilibrate much more rapidly. Try it!

Keep in mind the logarithmic nature of the pH scale. In the 'real world' this difference in pH amounts to: (10^-6.2)/(10^-6.6) = 2.5 times the amount of free H in the Chinook tea > Although, measuring at different times sometimes provided > different numbers, the spread was always the same and I > attributed the problem to lack of understanding of how to > use the instrument. The changes over time could be due to either temperature changes (although not in this case since you waited for the samples to cool) or they could be due to re-equilibration with atmospheric gasses (most notably CO2) after the sample was degassed by boiling. > The only significant anomaly was that on the third day, the > pH of both teas dropped to 5.7.

You may have something there, but I wonder what other types of acids might be present in hops that produce no flavor components. Ultimately we don't want to know the total acidity that the hops can produce in our beers, but the specific quantities of a particular class of acidic compounds.

Date: Tue, 13 Apr 1993 12:30 EDT From: HOWED at bcvax1.bc.edu Subject: More on Immersion Chillers After seeing all of the discussion on immersion wort chillers, I could not resist thowing in my paltry 2 cents. Before I started to brew, I saw a friend of mine do a batch. He had a wort chiller, and so I thought it was a great idea. So, I went to the hardware store, got 50' of 3/8 O.D.flexible copper tubing and a compression fitting. The coil is fit so that there is about 2 inches of spance between the coil and the side of the container for the wort. The outer coil just spirals down from the compression fitting [where the water comes in], then I made a much smaller coil inside the outer one which spirals up and out, where the water flows out. This chiller will cool wort which is fresh from the stove in about 15 mintues. Usually, I notice when the temp is at around 80 degrees [F], walk into the next room to tell my partner that it's just about ready, toss a dart or two, then come in to the 65 degree wort, all ready to pitch. All I can say is I have no complaints. It works for me.

Date: Tue, 13 Apr 93 11:56:42 CDT From: paulb%mist at juliet.ll.mit.edu (Paul Biron) Subject: rotten egg smell Last weekend I brewed up a batch of wheat beer using Alexander's 60/40 wheat extract, a 1.5 lb 100% wheat kicker, and various grains and hops. I used Yeastlab Bavarian wheat liquid yeast. Prior to brewing I made up a starter using 5 tbsp DME. After 24 hours in the starter there was quite a bit of activity as well as a good deal of sediment but minimal kreusen. I pitched into the primary and vigorous fermentation began within 18 hours. Once fermentation started, I began to notice a sour sulphur odor. Now that fermentation has stopped and I've racked to the secondary, the odor isn't as distinct but it's still there. Questions: 1: Has anyone had this experience using Yeastlab yeast. This is my first experience with it. I've always used Wyeast befor this batch. 2: Will the odor disappear with time. 3: Is there a chance that I have a contaminated batch. Any feedback will be appreciated Thanks.
