Date: Fri, 30 Aug 91 08:57:47 EDT From: card at apollo.hp.com Subject: 33 quart brewpots in Mass After looking "everywhere" for a 33 quart ceramic on steel brewpot, I finally decided yesterday to go mail-order and ordered it Great Fermentations for 32.95 plus ~ 7.00 postage/handling. Well, while out shopping with my wife last evening at KITCHENS ETCETERA, they had the very same pot (with a canning insert) for $34.95! *%^*# at &^ Oh well, that's $5 for the economy. /Mal Card p.s. BTW, I wasn't that impressed with the handles. As I picked it up and exerted a little pressure the handles seemed to move a bit, and you could hear the ceramic crunching. Moving 5 1/2 gallons of boiling wort from my stovetop to the sink for cooling might spell D-I-S-A-S-T-E-R. Any experiences out there? Return to table of contents

Naturally, I'm looking for ways to further streamline the process. Right now, the largest chunk of time involved is in the actual starch conversion. I use Miller as my primary homebrewing refer- ence. As you may know, he doesn't believe in iodine tests for starch conversion. Also, he often calls for two hour starch conversion rests. I think Miller's two hours is often out of line. I've had one brew which fermented down to an OG of 1.005 and another that reached 1.002! There's a dry beer for you (but this one has flavor!). This suggests to me that I've overconverted the starch and may be able to get by with a shorter starch conversion rest. But I don't know how to conduct such a test. Would someone please instruct me on the mechanics of performing such a test and how to interpret the results? Also any discussion of the limitations of the test wuold be appreciated.

Thirty-six hours after pitching, an almost frantic glug rate was achieved, but unfortunately, it was accompanied by a sweet, rotten-egg smell. Papazian says this is not unusual and that it can be avoided by changing yeast, but he says nothing about the impact on the current batch. Is this merely a passing phase? Will the brew be drinkable, or should it be reserved for slug bait? Any advice would be greatly appreciated. Thanks. Tom Conner Return to table of contents

Freedom, independence, security and dignity are fine, but what about the things that really matter? Before we go jumping on any political bandwagons, we need answers to a few questions. To wit: 1. I have never tasted Lithuanian, Latvian or Estonian beer. How good is it? What styles do they produce? 2. Was their beer better before Soviet annexation, or has it improved? 3. Do their legislatures recognize the sanctity of Home Brewing? 4. Are any of their leaders actual Home Brewers (or Brewers of any sort)? 5. Have they endorsed the proposal that Brewing become an Olympic event (as a replacement for synchronized turtle roping)? The pro-wine American press has deliberately withheld this information. Until we get answers, I say we withhold our endorsement. tim Return to table of contents

Date: Fri, 30 Aug 91 10:10:20 PDT From: chad at mpl.UCSD.EDU (Chad Epifanio) Subject: Simple yeast recycling Just to throw my humble opinion onto the growing pile: Due to the expense of liquid yeast and the difficiency of my salary, I am forced to reuse the previous yeast several times. My first step is to prepare several steril wort solutions for use in making starters for pitching. I take about 1.5 cups of dried malt extract, boil in about 2.5 pints of plain filtered tap water for about 45 min to an hour, with 0.25oz bitter hops(I used Bullions). Pour the boiling hot mixture through a strainer into sanitized 12oz beer bottles. It makes about 5 full bottles. If you fill it all the way to the top and cap immediatly, it will leave a 1.5in vacuum gap when it cools down. Make sure those bottles are preheated and are not on a cold countertop, or the sudden thermal gradient will crack them. Store the cooled bottles in the fridge until you need them. They shouldn't go bad if you fill them while the wort is still boiling hot. To use, I crack open a steril wort bottle and pour it into a sanitized wine bottle, fitted with a fermentation lock. Add whatever yeast you like. I use this for Wyeast packets to increase the pitching volume. Within a day or two, it should be revin' up and ready to go. The last batch of beer I made began bubbling within hour, and was *violently* active within four. Fermentation was completed in two days. I've also used a Yeast Bank in conjuction with the starter. I put a bit of the steril wort into a test tube, and added a bit of the yeast to it. It will ferment for a couple of days, and flocculate to the bottom. Pour off the top beer, add a bit of the included solution (glycerine?), shake to coat the yeast, and freeze. Bingo! You have yeast for your next starter without having to worry about slurries or trub. Notice that the yeast bank provides yeast for the starter, which provides more yeast for the yeast bank... When I brew within a few days of the last batch, I just grab a cup of slurry from the previous batch and store it in the fridge. When this much yeast is added to the wort, I usually get violent ferments starting in an hour or two. The whole point of this confession is that I am far too lazy to prepare a fresh starter for each batch. The prepared steril wort really makes thing easier.

Date: Fri Aug 30 11:03:03 1991 From: larryba at ingate.microsoft.COM Subject: Yeast reuse secrets This is really annoying: Just how do I address a letter directly to Father Barleywine? The following and several permutations were all bounced back. | | To: uunet!rransom at bchm1.aclcb.prudue.edu | Subject: Yeast reuse secrets | | Mr BarleyWine: | | You alluded to phases of yeast growth. Can you fill me in with some | more details? Is there a good reference? | | I collect the yeast portion of my primary cake. Ususally I can keep | the trub to a reasonable minimum by letting things settle naturally, | leave in a pint of wort after racking and swirling to stir up the top | layer of yeast. This doesn't always work since sometimes I rack too | soon and things haven't settled in nice layers. When this works, | however, I get a fat looking tan gloop that stores in the refer (35f) | under a little wort (1:1) for a couple of weeks and almost explodes | when dumped into the fresh batch o beer. It is most satisfying to be | at high krausen in 4 hours and be fermented out in 2-5 days (ale vs | lager). | | Does this sound reasonable? Sometimes it takes 6-8 weeks till the | next batch - yeast stored under these circumstances don't seem to | survive as well. Would storing under a couple o quarts of wort be | better? Would it be better to store under fresh unfermented wort - | or is it better to replace the old wort with fresh stuff a couple of | days prior to the brew to re-activate? | | I want to do a series of lagers. I have a good secondary yeast cake | in a 5 gal carboy, I am thinking of transfering it to my 7.5 gal one | for the rest of the lagers and pitch ala your suggestion. One | question: do you chill, let settle and rack off the trub before | dumping the new wort onto your yeast cake to avoid trub accumulation? | | Using your scheme, one would pretty much let the beer sit & | condition/lager until ready to brew the next batch, regardless of how | long the ferment took. | | Right? | | Thanks Return to table of contents

I'm going to try to bottle some homebrew and some homemade soda in plastic pop bottles. I have a small collection of one and two liter bottles. What I need is caps. Most of those bottles came with the aluminum caps and they don't hold pressure so well as the plastic ones. I have patiently clipped the rings left after unscrewing the cap for the first time from all the bottles. Now, where can I get some replacement caps. Does it take a special machine to install new twist off and leave a little ring caps, or do they just screw on and then break when screwed off. Even the plastic caps won't last very long, and I have a raft of 16 ounce plastic bottles I'm intending on using for transportation of homebrew. Caps! I need caps! I don't want my "MTV," I wnt my CAPS. Thanks to any or all who respond. Dan Graham, WA6CNN Beer made with the Derry air. Return to table of contents

Ah, but the enzymatic conversion of starches to sugars DOES occur at "natural" temperatures-- just a heck of a lot more slowly. As you say, Mother Nature's reason for the reactions in the first place is to nurture that little baby barley plant. The plant only needs the sugars a little at a time, over a period of days or weeks. We homebrewers, on the other hand, are an impatient lot. We want it all converted right now, not over the time period it takes the barley sprout to grow leaves large enough for photosynthesis to support it. What we're doing with those "unnatural" temperatures is simply speeding up the natural process. -Greg (cemax!greg at sj.ate.slb.com) Return to table of contents

Date: Fri, 30 Aug 91 17:18:05 -0400 From: buchman at marva2.ENET.DEC.COM (Dances with Workstations) Subject: Summary of replies re: Stout Bombs Hi, Thanks to the many responses on my overcarbonating stout. If you remember, I had a version of Toad Spit Stout (called Empirical Stout) whose ending gravity seemed high (1.020). Three days after bottling, a bottle that I opened was a mild gusher, so I yelled for help, lest I end up brewing a small arsenal of stout bombs. I got about five or six responses--thanks! Here's a summary: a) Several folks said not to worry about it; that a final gravity of 1.020 is not too high for a stout; and that ales frequently finish carbon- ating in just a few days, particularly when the weather has been warm. b) Most added that there is no problem in taking a specific gravity from the bottled beer as long as bubbles are not forming on the large, moving part of the hydrometer; doesn't matter if there are bubbles around the scale. Chip Hitchcock recommended first pouring the beer straight into a glass to kick up a big head, then letting the head subside to get rid of some of the carbonation. Also, there should be no need to compensate for the priming sugar in taking the gravity because it should be consumed by the yeast within three days. I did take a gravity reading of the stout on day 10 from a bottle which gushed when opened; it was still 1.020, so there were probably no excess fermentables being eaten by reawakened yeast, as I feared. c) Also, most advocated cooling the beer if I was worried about bottle bombs, since cool liquid can hold more dissolved CO2 than warm, and so be under less pressure. d) A good way to check for an impending detonation is to check for everted bottlecaps. Many cappers put a circular dimple in the bottlecap; an overpressurized bottle will tend to push that out. My capper puts the dimple in for most bottles but not all of them, e.g., NOT for Bud Dry longneck bottles; those which had it were not everted. e) Chuck Coronella recommended opening a bottle every few days to check for overcarbonation; if that is a problem, he has used this remedy with success: > . . . do this- get a bottle > opener and your bottle capper. One at a time, open each bottle slightly, > until the level of the foam reaches the cap. At this point, quickly clamp > that cap down, preventing any beer from leaving the bottle. He suggested that the trouble and wait will pay off: > . . . I made > a batch of Cushlomachree (?) stout from CJoHB about 18 months ago, and > ooooooh, it is so smooootthh now. As I recall, (don't have my notes here), > this beer had a small overcarbonation problem about two months after > bottling. Florian had one dismaying, but very good, piece of advice: > You should get rid of all your Fischer bottles. In all my years of > brewing, I have only had two bottles break. Both were Fischer and > in that batch, none of the others broke. The Fischer bottles are > simply too thin and are not meant to be re-used. Use Grolsch bottles > if you are lucky enough to get them, or order the Grolsch type > bottles out of Canada. Another source of resealable bottles are the more expensive Belgian ales, which often come in extra-thick ceramic bottles with Grolsch-style caps. A German beer which is simply called "Pils" also comes in such a bottle; but all of these are too expensive to buy more than very occassionally. I've accumulated about a case of the 22-oz Fischer bottles, and it would be a wrench to give them up. Perhaps they can be safely used for beers destined for the refrigerator, with monitoring. Then again, Florian is a cautious fellow: > ...

I monitored by opening a bottle every two days; most of them foamed up at least to the top of the bottle upon opening, and some overflowed. Here's what I finally did on day 10: - Put the batch (except for one "control" six-pack) into the refrigerator overnight. - Carefully popped and resealed the tops of all the Fischer bottles. - Opened all the other bottles and resealed with new caps. I didn't want to trust that the original caps would still seal well after being removed (even carefully) with a bottle opener. None of the cold bottles showed any tendancy to gush. - Warmed gradually back to cellar temperature. - Put into cardboard boxes in the back of the basement closet; to be opened in November. By cooling first, I hoped to prevent gushers/explosions, and also to force some carbonation back into solution; with luck this batch will therefore be neither over- or under-carbonated.

Speaker was Brook Ostrom, West Coast AHA competition organizer. Sept. Scheduled topic; "Cooking with Beer" Oct. Scheduled topic; "Fest Beer" (Okterber fest ect.) Nov. To be determined Dec. Annual club Christmas party I can offer some advice on how to prevent your meetings from turning into a "home brew free for all" : 1. Have a speaker or topic planed in advance of each meeting. 2. Publish a club news letter. 3. Do not allow drinking before or during the speaker's presentation. Its real tuff to keep control of the meeting when everyone is "relaxed and having a homebrew". 4. Have a mix of meetings through out the year; ie. some technical, some purely social. 5. Have a fixed schedule for the meeting dates. For the G.C.B.A. its the second Tuesday of every month. 6. Elect responsible club officers. 7. Ask that everyone who attends the meeting bring some homebrew or a commercial beer to share. 8. Try to boost membership to a "critical mass" by advertising at the local homebrew store, articles about the club in newspaper, announce club in Zymurgy. Hope this is of some help.

Date: Fri, 30 Aug 1991 18:57:56 EDT From: FATHER BARLEYWINE <rransom at bchm1.aclcb.purdue.edu> Subject: Screwy Tops, Fruity Beers. Relax! This posting has nothing to do with yeast cakes or magic... As a reply to the screw-top issue, I've been recapping screw-top bottles for quite some time. I like rebottling in beer bottles with pretty labels (like Boulder Beer, even though the beer that comes out of the bottles [at least in Indiana] is pretty average), and several of these pretty bottles have those nasty threaded tops. I've generally been of the snobbish 'if it's in a screw-top bottle, it's rubbish' philosophy (similar to the wine bottle without a cork in the top), but Sierra Nevada does it, so it can't be all bad. I find that capping the bottles is more difficult, but I have no trouble with the seal and if you don't care about your hands (or use a towel) you can actually twist them off. Admittedly, I have an old, cast iron monster of a capper, which can crush glass bottles if you torque it enough, but I just blithely capped them, and never had any problems. Adding fruit to beer yielded some mixed results in my brewery, since beautiful, juicy, fragrant fruits and berries when pastuerized and fermented in the presence of malt extract and hops can change character to the point of disaster. Peaches, one of my favorites, are particularly different after yeast gets through mucking with them. I (damn, inadvertant carriage return) ended up with 5 gallons of bitter, nasty brew. I have had triumphant success using fruit, fruit extracts (blended and strained fruit), and fruit juices added as described in the last HBD...added in the secondary (or in my case the primary) just before or with bottling. Less fermentation occurs in the presence of the fruit, and more aroma is retained. I finally managed a tasty and beautifully aromatic peach pale ale using mushed peaches on an extremely starting gravity ale (> 1.090) and letting them sit in mutual harmony for about 6 hours before racking and bottling. I prudently primed with just a touch of honey (1/2 cup) and the resulting mead- like brew was very pungent and actually tasted like peaches. I would also recommend trying a Belgian peach (Peche) beer by (I believe) Lindemann's. They use a similar process (but a decidedly different beer) and the taste of the final product is what I continually seek in my own fruit beers. Good luck with it, and keep trying. I think of myself as a fairly competent brewer, but it took me many brews to get what I could drink, much less a really superior beer (and I'm still working on a honey ale). This is probably an old old joke, but a German friend of mine drank a Bud light and remarked that 'this beer is so light that the head should be on the bottom'. Father B. Return to table of contents

Saikley and Jay Hersh seem baffled by Conn Copas' terminology: Conn Copas writes : >It's bemusing to >read posts in which people describe how they have conscientiously chilled >the wort, then pitched the yeast straight in on top ! And CR retorts: >OK, I'll bite. >What's unusual about chilling wort and putting yeast on top?? So, to move the discussion from obscure to impenetrable, I'll attempt a clarification. What I think Conn was saying is that we'll often take great care in producing our wort, only to entrust it to dry yeast which we haven't so much as rehydrated. We've often read (here and elsewhere) about the problems associated with using dry yeast (chiefly contamination, and strain selection emphasizing yeast survival rather than brewing characteristics) at all, but since the massive swing to liquid cultures a couple of years ago, we've almost forgotten about gently reviving dry yeast in warm water. Pitching the dry granules upon the wort shocks the yeast, subjecting the cells to osmotic stress, and usually producing off-flavors, negating altogether all that care ... = Martin A.

Lodahl <pbmoss!malodah at PacBell.COM> Subject: Mashing Wheat In HOMEBREW Digest #712, Bryan Gros was preparing to try wheat beer and all-grain brewing, simultaneously (points for courage!): >After two successful extract brews, i'd like to make a wheat beer. >due to cost considerations, i would like this to be my first all- >grain brew, but from reading, it seems that an 8-gal pot is needed >to hold everything. also a wort chiller which i don't have. Well, you could survive without the wort chiller, but you will need a kettle large enough to hold all the first runnings, sparge, and froth formed during the boil. For a 5-gallon batch, 8 gallons seems about the minimum. And the wort chiller really is a very good idea, as a rapid chill reduces the likelihood of infection, produces the "cold break" that will remove compounds from the wort that you really don't want to keep, and will greatly reduce the production of dimethyl sulfide (DMS), a large-scale producer of off flavors. >so maybe i'll just mash the wheat malt use add pale extract to >the wort. i haven't sat down and worked out the details yet, but >this may give me an introduction to mashing and save money. This is known as a "partial mash", and is a very good idea. Bryan, I would suggest postponing your first all-grain batch until you have done several partial mashes and are comfortable with the procedure. >Are there any special considerations i have missed? any suggestions? Yes. Mashing the wheat malt by itself is a waste of time and grain. >i just realized that the enzymes supplied by the barley would be >needed during the wheat mash, right? Right. > ... so i would have to add the >extract at the beginning of the mash. how would this affect the >amount of water needed during the mash? Wait! Most malt extracts are completely devoid of diastatic enzymes, so you can add all you want and it won't help the mash convert one bit. What you need is grain. Here, in general, is what you'll want to do: 1. Heat up 4 quarts of water to 135F. When it's there, add 1 pound of pale malted barley (or pale lager malt) and 2 pounds of wheat malt. Stir, stir, stir (with the heat off) until all the grain is thoroughly wet. A couple minutes at least. 2. Check the pH. It should be somewhere in the ballpark of 5.3 or so. Adjust downward by adding gypsum or upward by adding calcium carbonate. On no account add more than 2 tsp of either; if the pH is out of bounds, you're better off living with it than adding too much of the minerals. 3. Bring the temperature up to the range of 124-121F, stirring all the time, and keep it there 20 minutes (protein rest). It's okay of it fluctuates, as long as it stays in the range. You probably won't need to boost it back up more than once. 4. Raise the temperature to the 150-141F range, stirring as before. Keep it in that range at least 60 minutes; with this much wheat, 90 may be better. Unless you have an insulated box to keep your kettle in, recheck the temperature at least every 15 minutes. 5. While you're at a rest, start 2.5 gallons of water heating to 168F. Adjust the pH to 5.7. You'll need to improvise some sort of lauter tun here -- I used to use a large colander lined with cheesecloth, others have used spaghetti cookers. If your boiling kettle isn't in use either as a mash kettle or heating the sparge water, you can sparge directly into it. Otherwise, you'll need a clean receptacle large enough to hold all the liquid you've heated so far. 6. Your starch conversion (step 4) complete and your sparge water (step 5) ready, heat the mash to 168F. Let it sit for 5 minutes. 7. With your strainer mounted over its receptacle, pour the mash into it. I used to strain into a bucket, then move the strainer to the mash kettle (which I also used as a boiler), pour some of the wort from the bucket back through the strainer and use it to rinse all the grains out of the kettle and back into the bucket, then pour gently all the wort from the bucket through the strainer & grains again. The wort in the kettle would then be crystal clear. 8. Use the water you heated (168-165F) in step 5 to gently rinse the residual sugars from the grains (sparging). When this is done, put the resulting wort on to boil, and add the extract & hops when the boil begins. proceed as usual from there. This is by no means the only way to make a partial-mash wheat beer, but it will work. Some different times and temperatures would also work; the process is surprisingly resilient (and I'm accused of being uptight about it! ;-) Let us know how it turns out! = Martin A.

Lodahl <pbmoss!malodah at PacBell.COM> Subject: Mashing Pot (any way you want to take it) In HOMEBREW Digest #713, Darren Evans-Young asked the musical question: >Has anyone tried mashing pot? ...just kidding... Something over two decades ago (surely beyond the statute of limitations) a friend made an extract batch using a considerable quantity of said herb in place of hops. Don't know if it "worked"; the taste was too horrid for anyone to drink enough to find out. By the way, this topic touched off one of the few ugly flame wars this Digest has seen, several years ago. I hope we're all calmer this time. >Seriously, what size pot is needed to mash, say, 10 lbs of grain? >I already have a 10 gal SS pot to boil in. Is a 5 gal SS pot large enough >for mashing a maximum of 10 lbs of grain? It might be tight. I feel you'd be better off using a larger kettle (like your boiler), so you can stir vigorously without fear of sloshing over the edges. My mash kettle is smaller than 5 gallons, so I end up mashing in my boiler more then half the time. The mash kettle (and the spaghetti kettle, and sometimes the autoclave as well) are then pressed into service heating sparge water ... = Martin A.

It will be called the Woodstock Brewing Company. Kegging will begin at that time, with bottling to follow in the spring. I have no further information at this time, but this is enough to whet MY whistle. Anyone else with more information along these lines?? Yours in the Rumor Mill, STEVE Return to table of contents
Date: Sun, 01 Sep 91 23:32:47 EDT From: MS3Y at CORNELLA.cit.cornell.edu Subject: Re: Homebrew Digest #711 (August 28, 1991) Conn Copas asks (my paraphrase) if rolling or flaking has any effect on the cellulose content of adjuncts, as he believes cellulose to be a precursor to methanol in the final brew. Rolling, flaking or heat treatment should have next to zero effect on the cellulose content of adjuncts. Moreover, the cellulose content shouldn't matter since neither the mashing enzymes nor the yeast is capable of breaking down cellulose into its monomer form, glucose (same as corn sugar). Further, there is no direct chemical pathway between cellulose (or glucose) and methanol via any organism normally found in beer. Perhaps Conn is thinking of hemicellulose or lignins as a source of methanol. Hemicelluloses contain a few methyl esters and lignins are full of methyl ethers - but they should both be quite stable during the brewing process since specialized enzymes are needed to liberate the methanol. RDW - there is prob- ably far more methanol in your child's glass of apple or orange juice than in your home brew. Cheers - Jean Return to table of contents
