I've read a lot over the last two months about Wyeast. I've brewed for many years with Edme dry yeast, but I'm interested in trying some Wyeast. I asked the people at Wines, Inc, but they don't carry it. Can someone post to the list or send me the name, address, and phone number of a mail order company that carries Wyeast? I have kegged all of my homebrew for the last six years. For several years I used a hand held tap. I never had any problems with mold forming on the end of it. I think that is because the hose and tap were always stored in the beer refrigerator. I replaced it with a through-the-door tap, and ever since then have had problems with mold forming on the part of the tap that sticks through the door. If I get lazy, or forget to check it, the mold will eventually work its way up into the tap. Running very hot (close to boiling) water through the system once a week doesn't seem to prevent this problem. Nothing seems to work except disassembling the entire tap, boiling and hand cleaning it. A very tiresome procedure. How do bars handle this problem? Do they use something besides boiling water to sterilize? Would a different tap help? I'm planning on trying covering the tap with a balloon (or something similar) when its not in use. Comments? Chuck Cox recently announced that he had a stainless steel counter pressure bottle filler for filling bottles. Could you please provide more details? Where did you get it? How does it operate? Does it work well? Thanks.

Well I tried this in my last batch, and I noticed no > such foaming and my sour type flavor was still their. However this > batch did come out to be my clearest beer yet! I think the Polycar > caued this result, after all it's a fining agent. I can't comment on the sour flavor you describe but I have used polycar in about 12 or so batches. The amount I use comes in packets of 1/4 oz. I have used 1/2 oz. sizes also. From my experience this is the acceptable range. If you followed Miller's steps then there is one pitfall he does not outline. Miller recommends diverting a small amount of beer into a pan and then stirring in the polycar before pitching into a fermenter. To create the effusion of CO2 you must add the polycar mixture to the fermenter immediately -- no lag time. I remember one batch I diverted some wort into a pan at the begining of the process, added the polycar and waited for the beer to completly fill the new fermenter/clearing tank. The zing was not there, no CO2. Because of this experience, I don't add the polycar to the pan until the fermenter has been completly racked. And then add the polycar solution as quickly as possible after it has been suffiently mixed. One final observation. 1/4 oz. polycar does not cause foaming, 1/2 oz. will. However 1/4 oz. causes an airlock to kick like mad for about 5 minutes. gerald at caen.engin.umich.edu (Gerald Andrew Winters) Return to table of contents
Date: Mon, 13 Aug 90 08:52:28 -0700 From: cckweiss at castor.ucdavis.edu Subject: snowbrew, glass primary fermentors So, I'm not crazy after all... The snowflakes described by Keith Thompson are *exactly* what I am seeing in my beer. I sent Keith a detailed post of my recipes and procedures, so we can compare and see if there's a common element. A question for those of you using glass primary fermentors - How do you get five gallons of hops-filled wort strained and inside a glass carboy without making a HUGE mess? I thought of a big funnel, but it seems like once the hops started collecting in the strainer section the flow rate would be too slow. Please to enlighten me!

Of nearby fellow brewers some experience this same problem, whereas >others never experience it. We're all basically do the same thing. Exactly the same thing happened to me with my first three batches of homebrew. Various sugars were used as additives, always with the resultant beer being at first flat, then more and more carbonated. In addition, the carbonation was "thin", that is, it went away quickly like a soda's would. This condition actually made me stop brewing for about a year, until I started reading this digest. Following the advice of many helpful suggestions made in this digest, I began to brew again, but used steeped grains as the additive (removed from the brewing water just as it comes to a boil) and also switched to liquid yeast. I don't know which of the two changes is responcible, but my brew now has perfect carbonation in every bottle! My advice: don't use sugar as the additive. Steeped grains are easy to use, and add a great deal to extract brews. A question for the readership: Was the exploding Wyeast problem ever resolved? Is there a consensus on how long one can safely wait with a fully puffed pouch before it will explode? Thanks for all the great advice!

Date: Mon, 13 Aug 90 13:00:24 EDT From: FRISRM%morekypr at pucc.PRINCETON.EDU Subject: bottle cappers Has anyone tried to make their own bottle capper? I've been bottling into mason jars and although I have learned to cope with drinking my homebrew by the quart ;-) I would rather not have to buy another case of jars to be able to age my beer and insure a constant supply. So, I'm going to try bottling (hopefully with a homemade bottle capper). Any ideas about how to make one would be appreciated.

Date: Mon, 13 Aug 90 12:27:59 EDT From: cjh at vallance.eng.ileaf.com (Chip Hitchcock) Subject: ice-based wort chiller Your calculations neglect one factor: efficiency of transfer of heat. 5 gallons is almost a cubic foot. If you have only 4 feet of tubing in this space, the immediate neighborhood of the tube will get quite warm without necessarily distributing that heat to the rest of the ice bath. Also, crushed ice, being solid, will mostly not be in contact with the tubing until the ice melts. In practice, I'd expect that you wouldn't chill the wort nearly as much as you calculate with this design---you might not even melt all the ice. I'd suggest \at/ \least/ enough water to cover the ice---preferably enough that you can stir the bath or at least move the tube occasionally. You'd get better contact/efficiency by mixing ice and salt and letting it slush, but the salt would attack the copper (don't ask me how long the copper would last). You also left out of your calculations the fact that if the ice were melted, you'd still have 5 gallons of water at 32F, which means that in theory the wort could wind up at (32+69)/2 = 50F. (Also the ice itself probably averages 10-15F, since your freezer should be around 0F.) In practice this will probably just make up for heat transfer from the atmosphere to the bath unless you use a cooler to hold the ice/water. Something else I'd worry about in this rig: with that much temperature drop you could get a hell of a cold break and pile up enough coagulated protein to plug the tube. Depending on the brand, you can get protein even in extract (you should see the fernlike sheets I found in a can of M&F Old Ale). Return to table of contents
Date: Mon, 13 Aug 90 11:13:10 PDT From: aimla!diamond!ken at suntzu.West.Sun.COM (Ken Ellinwood) Subject: Artificial Carbonation In digest #437 Chuck Cox reports that ... > Byron connects the CO2 to the down-tube, thus forcing the gas to > bubble up through the beer, increasing the rate of absorption. > I think this is a great idea, I just need to buy some more fittings > and tubing to implement it. Essentially we do the same thing, except that instead of connecting the CO2 to the "out" side, we turn the keg upside down and then turn the CO2 on to allow it to bubble up through the beer. Also, I have heard that the absorbtion rate is much higher if the beer has been chilled first when this technique is used. - Ken Ellinwood - Return to table of contents
Date: Mon, 13 Aug 90 12:47:06 PDT From: dsbaer at EBay.Sun.COM (David Baer) Subject: Chillin' In response to "mike_schrempp%29 at hp4200.desk.hp.com" regarding his wort chiller proposal to save water: I also try to save water when I use my wort chiller. I purchased an inexpensive ($25.00) fountain pump that I attach to a short lenght of hose and place in the bottom of a 20 gallon trash can. I fill the trash can about 1/2 full with ice and water. I use large blocks of ice because they tend to keep the water colder longer than crushed or cubes. I then pump the water through the chiller and back into the trash can. As I see the block of ice melt to almost nothing, I add another one. Typically a chillin` session takes about three blocks of ice and 20 minutes. The wort falls from boiling (212 F to 80 F). If I need it colder then I'll add cold water to the wort, but right now I am big on ales and don't mind pitching at 80 F. I figure I use about 10 gallons of water to chill the wort, clean the chiller and brewpot, and finally as a water bath to keep the temperature fairly constant.

Date: Mon, 13 Aug 90 16:33:26 EDT From: capnal at aqua.whoi.edu (Alan Duester) Subject: beer tasting in Boston I just found out about a beer tasting in Boston, MA. Radio station WBUR is having a benefit (for themselves - public/college radio) beer tasting on Thursday the 16th of August, from 6 to 10 p.m. at 808 Commonwealth Ave. Station phone # is (617) 353-2790. They said they were going to have 25 microbreweries, and 60 or so beers represented. 10 food booths or vendors of some kind as well. It's near the BU bridge, and the nearest stop is the BU west stop on The Green line 'B' train. They've never had good publicity on this event in the past, and I usually find out about it weeks after it happens. I haven't seen anything on this year's either here, or in the Boston Wort Processors newsletter. Chuck - I can't seem to get mail to you - I was trying to inquire about this. ========================================================================= "The farther it gets from the bench it was built on, the more real the real world gets." - Todd Johnson Al Duester, Ocean Engineer, MS S201 # SPAN: 6308::capnal Woods Hole Oceanographic Institution # INTERNET: capnal at aqua.whoi.edu Woods Hole, MA 02543 # GEnie: A.DUESTER (508) 548-1400 x2474 (ans.

Date: 13 Aug 90 15:46 EDT From: Patrick J. Waara <Waara.wbst at Xerox.COM> Subject: Lagering I would like to attempt a lager, but know little about how to go about it. I realize there are restrictions as to how quickly you should chill your wort and all that, and I have seen an occassional mention of lagering in this digest, but I have not really seen a good, complete description of the process. Is there a standard text on lagering, and/or could someone describe in detail the lagering process; perhaps suggest a good lager recipe at the same time? I should point out that I am essentially a beginner (6 batches so far), so please be as specific and detailed as reasonably possible. ~Pat Return to table of contents
Date: Mon, 13 Aug 90 16:51:11 PDT From: winter%cirrusl at oliveb.ATC.olivetti.com (Keith Winter) Subject: Thanks for the help with over-carbonation! I wish to extend my thanks and appreciation for all of the responses (both in the digest and directly via email) to my question regarding over-carbonation. The volume of useful suggestions and personal observations shows, once again, how much this digest serves the home brewer! A couple of comments regarding some of the responses: 1) It was suggested by a number of people that I may not have waited long enough before bottling and thus fermentation wasn't complete. This would cause the problem if fermentation then completed in the bottle. I don't think this is the problem. I take SG readings at least twice after I rack from the primary to the secondary and don't bottle until I see no significant change for two days. In the case of the Pale Ale that I was specifically asking about, the SG readings were: 1.064 (OG), 1.019 when racked to secondary after three days, 1.017 after 10 days, bottled after 12 days when the SG was 1.016. 2) A few folks mentioned problems related to Edme and wild yeasts that start a late fermentation in the bottle. It was suggested that maybe I should try liquid yeast (Wyeast) cultures. This may be a part of my problem. My records show that both of the batches that have been over-carbonated were made using Edme. It should be noted that I've used Edme without problems but that may not necessarily eliminate it as the cause. I think that I will try the liquid culture on my next batch. Any suggestions on a particular Wyeast that would approximate the yeast that Sierra Nevada uses in its Pale Ale? 3) Possible infections from using a plastic primary. I think that I will go out and purchase a glass carboy for doing my primary. It is possible that the plastic bucket is allowing wild "junk" into my brew, although I haven't been able to discern any scratches or abrasions. I've been wanting to move to a blow-off mode of primary anyway, I guess now is a good time to bite the bullet and go spend some money. Just for the record, the secondary I use is a 7.5 gallon glass carboy. An additional comment: the over-carbonation is getting worse. I guess I'll just have to invite a bunch of friends over and finish it off :-). The ale really is good so I sure don't want to waste it just to avoid glass hand-grenades.

Date: Mon, 13 Aug 90 21:12:19 CDT From: "John P. Quintana" <jpq_mail at laue.ms.nwu.edu> Subject: Sour Smelling Beer In an effort to understand my beer better, I have been occasionally smelling the CO2 gas that comes out of my airlock on my plastic fermentation vessel. I just bottled a standard kit brew with some extra hops and I noticed something that I had smelled before. While the beer was fermenting, the gas out of the airlock smelled "fresh". The day after I opened the vessel to add finings (isinglass) according to the recipe, I noticed that the odor from the airlock was definitely sour. As I bottled the beer, the new beer also had a slight sour off taste. I'm hoping that as the beer ages, this will go away. I've noticed it before in some previous brew, but this is the first time that I've kept carefull notes. Anyone have an idea of what this might be? An infection perhaps? - John Return to table of contents
Date: 13 Aug 90 20:52:24 EDT From: jay s hersh <75140.350 at compuserve.com> Subject: oatmeal stout To Patrick - I believe the oatmeal stout was from the recipes I posted. Glad to hear it appears to be turning out well. Has anyone else brewed a variation on this recipe (or the recipe as posted). Like I mentioned this one has always been a winner when I've brewed it.
