Thanks to all who showed interest in the Grolsch bottles. I cannot respond to all personally, so thank you, and I'm sorry I didn't have enough to go around. Kegging, here I come. Since I'm attempting this 'blind' so to speak, I'll keep y'all posted as to how to keg without being aboe to see. Dan ... Beer made with the Derry air. Return to table of contents

Jack, This was not made clear to the other participants in the seminar or me, so maybe Jean misunderstood the nature of the samples. I got the impression from your HBD digest postings that you wanted an evaluation of your beers, as well as an estimate of how effective your distillation process is. In either aspect, lack of sanitation (albeit intentional) will destroy any accurate measurement. For example, depending on the amount of oxygen available, lactic acid bacteria will either metabolize ethanol or fermentable carbohydrates. Acetic acid bacteria, which is common in beer dispense lines, uses ethanol as its source of carbon. Thus the apparent alcohol content may or may not be representative of the original, sterile beer. Jean has not been intentionally procrastinating on the HPLC measurement of the alcohol content; she is up for tenure at Cornell next month, so I'm sure she will get back to this matter after that hellish procedure is finished. And by the way, judging a beer that scored in the low 20's is not my idea of fun. But thanks for pointing out that the taste and alcohol content was not representative of your homebrews. Cheers, Scott Return to table of contents
Date: Wed, 22 Apr 92 6:47:10 PDT From: jal at techbook.com (Jim Larsen) Subject: Stainless Steel Greetings: I am in recent receipt of a Cornelius kegging system and I have a few questions regarding its care and feeding. 1. How does one ferment in steel? I know of brewers who split the primary into two five-gallon vessels, relieving the pressure at regular intervals, and counter-pressure transfer to a single secondary. Others remove the fittings and tubes and replace them with blowoff tubes for primary and counter-pressure transfer to primary as well. 2. What are the preferred cleaners/sanitizers for stainless? I know of those who swear by between TSP or Iodophor, and one who even uses bleach with minimum exposure. 3. My current Cornelius inventory consists of one five-gallon and one three-gallon. In addition, I have a Firestone I acquired from a generous Coca-Cola driver. I there a simple means to incorporate this into my system, or should I seek to replace it with another Cornelius? Thanks, jal Return to table of contents

So I am a bit surprised that they would tell others that they air freight it...or have they expanded? Any explanation would be appreciated. Send personal email or to the list, and if you do, could you include the 1-800 #? Any input is vastly appreciated!

Does anyone have a way to measure the amount of fermentable versus non-fermentable sugars in the sweet wort? - --Eric Return to table of contents
Date: Wed, 22 Apr 92 10:42:30 PDT From: bgros at sensitivity.berkeley.edu (Bryan Gros) Subject: Fermenting Steam beer I'm fermenting a steam beer right now. For various reasons, my primary fermenter is an open plastic bucket. The beer is bubbling away, and in a couple of days I will rack off the trub into my glass carboy. (This is the first time I'm using a secondary fermenter. Too bad I don't have the fridge space to lager). My question is, since the Wyest cal. lager yeast is bottom fermenting, and I rack into the carboy leaving the stuff on the bottom behind, will I leave all my yeast behind? Or will I get enough to finish the fermentation? Thanks. - Bryan BTW, should I be skimming the foam out of the bucket? Or was this the topic with no consensus? Return to table of contents

I'd say that 1007 is unusually vigorous, not that the others are lethargic. When my brew partner and I first acquired some 7 gallon carboys we stopped using a blow-off hose. For most of the yeast strains we used- 1028, 1056, 1098- this was no problem. Then we tried 1007 for the first time. Yeast sludge all over the basement. Beer tasted great, though.

Hmm, I hope we can resolve this issue: I used yeast cultured from a bottle of SNPA for my latest pale ale, which is still in secondary. The thing I noticed about the yeast was that there was very little sediment on the bottom when I racked to secondary, and that the cap of foam on top (it never collapsed) was _very_ thick and sticky, like peanut butter in consistency. That would make sense if I used a specially sticky bottling strain to ferment with. Still, the hydrometer sample tasted fine. Let's hear it for Sierra Nevada Pale Ale! Hop hop hooray!

Date: Wed, 22 Apr 92 14:19:13 CDT From: pmiller at mmm.com Subject: Clear bottles I agree with Geoff Sherwood. My beer looks a lot better in clear Newcastle Brown Ale bottles than any brown long neck bottles. I also store my bottles in long neck cardboard cases and have never had a problem with light-struck beer. (Of course, the original Newcastle Brown Ale that had been sitting for who knows how long under the fluorescent lights in the liquor store is another story :) Phil Miller Return to table of contents

Date: Wed, 22 Apr 92 14:58:32 CDT From: Darren Evans-Young <DARREN at ua1vm.ua.edu> Subject: Low mash pH I've recently gone all-grain and have a sort of problem. All my water is preboiled and cooled to remove chlorine. Tuscaloosa, AL water is moderately soft. I heat my mash water to the correct strike temperature, dump in my grains and stir well for 5 minutes. Then I remove a sample of the liquid and test the pH. According to my battery operated pH meter (properly calibrated), my pH is 4.8. I have verified this with pH papers too. I've added as much as 2 tsp of CaCO3 to bring the pH up to the recommended 5.2-5.4 range, but it doesnt budge. I do make sure to stir in the CaCO3 well before taking another reading. My question, what is the effect on the mash with a pH that low? Benificial or not? Should I continue to add more CaCO3? Should I not worry and be happy with a 4.8 pH?

Date: Wed, 22 Apr 1992 13:17 PDT From: Bob Jones <BJONES at NOVA.llnl.gov> Subject: Spent grain & Romulan Ale from Micah Millspaw What to do with spent grains? I brew 15 gallon batches and often end up with 30-40 pounds of spent grain, not to mention used hops covered with clumps of protein from the boil(yuk). I used to trade the grain for eggs with a friend who had chickens. Unfortunately the birds stopped laying (to old) and I can get free eggs anyway. So, one of the guys I ride to work with raises llamhas(sp?) and they seem to eat everything, I don't get any thing out of this but it is conveinent and my kids like to watch the llamhas eat. And the llamhas really like the used hops! Micah Millspaw 4/16/92 The Romulan ale has been brewed! I call it S'harien, it is an all grain wheatwine, 50% wheat, OG 1104 with 65 IBU's. On the colour end of it, I'm going with food colouring but am adding it to the bottles just before I counter-pressure fill them. No draft Romulan ale for me. This stuff should be ready by conference time, I intend to bring some. Thanks for the many suggestions HBDers. Micah Millspaw 4/21/92 Return to table of contents
Date: Wed, 22 Apr 92 14:20:04 PDT From: bgros at sensitivity.berkeley.edu (Bryan Gros) Subject: HBUs and IBUs??? I was designing my recipe for my steam beer (see post above) and bought some Northern Brewer hops. The store said 8.5% AA. I noticed most recipes for an Anchor-type beer said 13 or 14 HBUs. This means about 1.5oz in my 5-gallon batch. I checked Eckhardt and he said steam beer: 35-40 IBUs. I decided to take the plunge and figure out IBUs. If I use the formula in Papazian or the Zymurgy issue, I get something like 1/2 oz for 60min. (Don't have the formula with me). So how can these two different measurements be off by so much? Is this why all my beers so far have been pretty darn hoppy? Should I just switch to IBU calculations and go by experience? I ended up comprimising and using 3/4 oz for 60min, 1/4 oz for 30 min, and 1/3oz for flavoring. I have no idea what it will taste like. (I'm considering dry-hopping slightly, but I'm not sure how much I would add.) Any advice would be helpful. - Bryan Return to table of contents
Date: 22 Apr 1992 21:07:06 -0600 From: "Brett Lindenbach" <Brett_Lindenbach at qms1.life.uiuc.edu> Subject: None Subject: Time:8:39 PM OFFICE MEMO None Date:4/22/92 sorry about the format of my last post. anyways, about the carboy kegging. i use 19 liter carboys from my lab. they are made of thick pyrex (great for autoclaving), with a wide (57 mm) mouth and large lip. i have only seen them in scientific catalogs (thomas scientific, p.135, 1-800-345-2100), and they are a little pricey ($113.26). my suggestion is that anyone who has access to some of these suckers, *use them*, but they may be a little out of the price range of most homebrewers. anyways, they take a size 12 stopper. so i drilled two holes in a stopper, of appropriate diameter for two glass tubes, one short one for pressure, one for drawing off the bottom. the connections (CO2, tap) were made with sterilizable nalgene tubing held tight with clamps, and sealed with dow/corning high vacuum grease. now, the most important piece: the stopper clamp. this consists of a *large* washer-like piece of steel of about 57 mm o.d., 50 mm i.d., which fits over the stopper, and has four equidistant holes drilled in it, each about 3 mm. picture that? ok, these holes are for bolts to go through, which are being held in place under the lip by a pair of hemicircular steel bands, which are in turn screwed together around the neck, tight enough so that the lip cannot pass through. thus, with a few twists with a wing nut, the stopper is absolutely clamped into place. this device was designed for the fermentation of a strictly anaerobic methanogenic bacteria, but it serves my purpose well. anyways, i have used a commercial CO2 regulator and tap mounted in a friend's fridge (keg-o-lator style). i prime in this device, and keep it under 5 psi while it is carbonating. in 2 weeks, it is ready to pull. best of all, it didn't cost any more than bottling. good luck to any i have inspired. i will comment on yeast culturing soon. -brett lindenbach Return to table of contents
