---------------------------------------------------------------------- Date: Mon, 6 Jul 1992 11:03:21 +0100 From: G.A.Cooper at qmw.ac.uk Mark asks about: >floating obnoxiously on the surface of my unfortunate mead is a layer of >(for lack of a more poetic term) SCUM. A quick nasal scan shows that nothing >smells afoul however. If it started as a white film that gradually got thicker but still basically white, it is probably Candida mycoderma. If so it has a nasty habit of converting alcohol to CO2 and water. If caught early, little harm will be done. Carefully remove as much scum as possible from the surface, siphon off (filtering is helpful) and treat at 50ppm with SO2 (If problems persist try 100ppm SO2). If you find sulphite undersirable, you need to find some other way of knocking out the Candida, or bottle and drink it. The problem if often associated with neglect, so, again, it is often accompanied by oxidation and other related niceties. Good luck. Geoff Return to table of contents

Date: Mon, 6 Jul 92 05:44:11 PDT From: cole%nevis.hepnet at Lbl.Gov Subject: re: rolled oats >In issue 910 Larry Barrello was replying to Chris Estes re. Pearled Barley. >Larry mentioned the use of rolled oats and barley. I tried mailing to Larry >directly but could not get anything through. > >My question is this. Are these regular, grocery store, rolled oats? How much >and when would you add these? Do they add to head retention? Are >Beta-glucans harmful? I do not have anywhere near as much brewing experience as Larrry. However, I personally would not recommend using rolled oats (at least in extract recipes). I used them in an oatmeal stout several months ago when I could not find steel-cut oats. I included them in an extract-based recipe in the standard manner of adding them to the boil water as it was being heated. I was quite nervous (but not worried !) that they would turn into oatmeal so I made sure not to let them boil and even removed them earlier than I normally would have removed specialty grains. I cooled the wort before transferring to the primary and after cooling I could see in the wort very vicsous thick whitish trub that took many days to settle out. When it did it left a 3-4" layer on the bottom of the carboy. When I racked to secondary I was not too surprised to find what was basically oatmeal sans oats, the same glutinous whitish paste that's in cooked oatmeal. Unfortunately while in the primary this "oatmeal" swelled and sucked up about 1/2 gallon of my beer. In addition, the head retention of my stout is pretty poor, it only lasts for 0.5-1.0 minutes. This may simply be due to the oils in the oatmeal and may have nothing to do with using rolled oats. I, however, will not use rolled oats again. I have since found steel-cut oats in local health-food stores. Brian Cole Return to table of contents
Date: Mon, 6 Jul 1992 10:01:56 -0400 (EDT) From: R_GELINAS at UNHH.UNH.EDU (Russ Gelinas) Subject: how thick is thick? Well, that's what you get with *scientists* on a mailing list ;-) Density(SG) and viscosity(thickness) *are* different things. But, most people think of dense syrup as "thick", and most people have experienced cold syrup as being "thicker" than hot syrup. It may be tecnically incorrect, but the mental picture of the "thickness" of syrup with respect to its temperature is clear. Russ Hey js, is this #100, or should I post another 99 one-liners to make sure? Return to table of contents

I usually use homegrown jalapenos for this, blending them first to homogeneity using a blender at the highest speed setting. ... And about root beer ... Beware that "naturally" flavored root beer from home recipes may contain carcinogens. This is why the commercially available root beers are generally artificially flavored.

Date: Mon, 6 Jul 92 10:29:12 PDT From: sami at scic.intel.com (Sam Israelit) Subject: Peach Weizen I was up until 1:30 this morning putting my attempt at a Peach Weizen comfortably to bed. I used a modified version of the TCJOHB recipe for weizen and 11 lbs of California white peaches (pitted and crushed with skins). Ended up with an OG of 1.061 and the yeasts were frolicking wildly by 7:30 this morning. I plan to rack this hopeful brew after the primary and leave in the secondary for roughly 2 weeks. I have two questions: 1). Is there any consensus as to whether there is a benefit to adding more in the secondary? 2). I can get a jar of Widmer hefeweizen which has a large amount of yeast in it. I have been told that they add their yeast as a second strain later in the process. It is a more flocculent (Why does that word always bring images of gaunt monks in cold-floored stone cells in the mountains?) strain from what I have heard. I was wondering if I should try to form a starter of this yeast from the dregs of a jar and pitch this with my brew. When do I pitch the second strain? What are the advantages to this? Are there any disadvantages? Is this a dumb idea all together? Any and all coments will be summarized to the net. Thanks in advance for any remotely constructive advice.

Date: Mon, 6 Jul 92 09:57:03 PDT From: thomasf at deschutes.ico.tek.com (Thomas D. Feller) Subject: Silicon There have been a number of post about using Silicon as a sealer for homebrew projects. Some folks have suggested using automotive silicon sealer because of temperature requirements, as a former auto mechanic I think this would be unwise. All of the automotive grade silicon sealers I have used have a high level of solvents in them. Granted, once they are dry they will hold up to almost anything, I would still be quite worried about contact with things I that I might eat or drink. Perhaps someone out there knows of a food grade silicon sealer which would have the same kind of properties but we would know it was safe for contract with food. Happy Brewing Tom Feller PS I will be working and drinking at this years Oregon Brew Festival and would love to see some other HBDer's. Send me mail and we well try to set something up.

Date: Mon, 6 Jul 92 20:18:52 BST From: Conn Copas <C.V.Copas at lut.ac.uk> Subject: Scum on old mead An aerobic scum on a high alcohol brew suggests you could have something like a sherry flor. It typically oxidises the alcohols to aldehydes, although apparently with far more refined results than is achieved by over-aeration. >From memory, it also metabolises certain acids in the brew. Even amongst the professionals, production of a flor is something of a random affair. Those brews which fail to develop one are sweetened and sold young. Those brews which develop one are allowed to ferment as long as possible until the flor drops by its own volition. Provided it is not some nasty which is souring the brew, it could result in some interesting accelerated ageing effects. - -- Loughborough University of Technology tel : (0509)263171 ext 4164 Computer-Human Interaction Research Centre fax : (0509)610815 Leicestershire LE11 3TU e-mail - (Janet):C.V.Copas at uk.ac.lut G Britain (Internet):C.V.Copas%lut.ac.uk at nsfnet-relay.ac.uk Return to table of contents
Date: Mon, 6 Jul 92 12:40 PDT From: Brian_Carroll at 3mail.3com.com Subject: Kegs I've picked up two ball lock soda kegs at the scrap yard for $3.00 ea. and have some questions about cleaning, and the carbination in brew use. 1)When you place new gaskets in them do you need to take the ball lock studs off and replace their gaskets? 2)Is soaking them in a TSP chloride solution sufficiant for cleaning, and will that get out the soda taste? 3)How long (if #2 is correct) do I need to soak them to get rid of the soda taste? 4)I've know that you need not to prime with corn sugar, hence the carbonation is added thru the co2 tank. But would it not help get rid of unwanted oxygen while aging? 5)After tapping how long will the beer stay good? Can you fill the keg with co2 to make it last longer?(Oh, I forgot to mention I don't have the facilitys to keep it cold after tapping.) 6)Sense the soda kegs take the beer from the bottom how much of the beer will have the yeast in it? 7)Should I use some type of filter while racking into the keg? If so what type of filter is easily used in home brewing, and how can you make sure of sterilization? (I've thought of cheese cloth but have no clue on how tho sterilize it.) 8)(this is'nt really a question I'd just like to get some feedback and maybe some better Idias for cooling the beer to drink) Ok, here is how I plan to cool it. I bought a 20 qt. cooler and 25 ft of stainless steel tubing in a coil that sits inside the cooler. The beer comes from the keg thru a plastic tube to the cooler into a coupler shank into the stainless steel tubing into a faucet and shank set. Wala! beer! I figure 5 min after I place Ice on the coil I should have cold brew in the mug. I'll use silcon to prevent leakage were I drill out the cooler.

TAYLOR " <S94TAYLOR at usuhsb.ucc.usuhs.nnmc.navy.mil> Subject: Silicone-General Consensus Just a semi-amusing aside to the discussion on the "inertness" of silicone: About 20-25 years ago, the general consensus in the scientific community, allegedly in the know, that silicone was inert in breast implants and the like. Well, that turned out to be not quite true. However, as long as you don't use the beer exposed to silicone gel for cosmetic augmentation, you should be alright. :-) Al Taylor Uniformed Services University School of Medicine Bethesda, Maryland Return to table of contents
Date: Mon, 6 Jul 92 14:50:22 PDT From: grumpy!cr at uunet.UU.NET (C.R. Saikley) Subject: Belgian Impressions - Part 1 Greetings Brewers, I've just returned from the WORLD'S GREATEST BEER SAFARI, a one week tour of Belgium. In my six days there, I visited nine breweries (but was unable to tour two of them), and three times that many cafes. I tasted lots o' beers, met many friendly people, and learned a wealth about the brewing scene in Belgium. The good news is that Belgium has by far the greatest variety in its beers of any country in the world. They take their beer seriously and it is served with respect. Each beer is served in the appropriate glass, often with its own coaster. Beer is considered the ideal accompaniment with a meal, and many dishes are prepared with beer. If you are looking for unique and interesting beers, nowhere will you find more than in Belgium. On the down side, the oft repeated theme of the Big Guys swallowing up the little guys is running rampant in Belgium today. This past year has seen the closure or takeover of 15 small breweries, including two brewers of Lambic in Pajottenland. The two major brewers of industrial Pils, Jupiler and Stella, have merged to form a large brewing consortium called Interbrew. Maes, another large brewer is part of a larger French company. Furthermore, Heineken appears to be flexing its muscles as well. Each year, more of the small traditional breweries are forced out of business by the consortia. The three largest lambic brewers have already succumbed to this. The largest is Belle Vue, with an annual production of about 250,000 hectoliters. They are now a part of Interbrew. Next is Mort Subite (100,000 HL), which is owned by Maes. Third on the list is St. Louis (50,000 HL), which some industry sources claim is backed by Heineken. Against these odds, the smaller, more traditional brewers of lambic are fighting for their very existence. The remaining little guys are producing some wonderful products. My standard of comparison between lambic brewers is their gueuze. Gueuze is a blend of one, two, and sometimes three year old lambics. It is traditionally refermented in the bottle, though the larger brewers no longer do this. The examples I sampled are listed below in order of my personal preference. 1. Frank Boon (pronounced Bone) 2. Cantillon 3. Vander Velden 4. Girardin 5. Timmereman's 6. Mort Subite 7. De Neve 8. Lindeman's 9. St. Louis 10. Belle Vue Being a lover of the traditional stuff, I did not expect anyone to produce a gueuze that I'd prefer to Cantillon, but Mr. Boon has done just that. His product is extremely complex. It has the cutting sharpness of lactic acid, but is rounded by the richness produced by Brettanomyces and other wild yeasts. Mr. Boon revealed that his beer's complexity was due not only to the Brett. and Pediococcus, but to a host of other micro organisms as well. I had made it clear to him that I intended to publish an article based on our interview, and he declined to discuss just what these other critters were. I described to him the "Guinard Method" for making lambics outside of Pajottenland. While he was fascinated that people were doing this at home, he contended (as does Michael Matucheski) that a fully developed gueze could not be produced using Sacharromyces, Brettanomyces and Pediococcus alone. Furthermore, he confirmed what Mike Sharp's and Martin Lodahl's experiments suggest, that aging in wood is crucial to the development of Brettanomyces character. By comparison, the gueuze made at Cantillon seemed rather one dimensional. It was extremely acidic, but lacked the fuller flavor of FB gueuze. If other lovers of lambic out there get the opportunity to sample both, I'd like to compare tasting notes. When I discussed the sourness of Cantillon's beers with JP Van Roy, the head brewer there, his attitude was that it was a traditional process subject to the whims of mother nature. You basically got what you got. Mr. Boon disagreed. He maintained that within the constraints of the traditional process, one could vary the product greatly. For example, he felt that thru proper treatment of the barrels, one could favor some microbes over others, thereby effecting changes in the final product. He has worked hard to fine tune a complex process, and it shows. Another bit of good news, sometime later this year we can expect to see limited quantities of Frank Boon Gueuze and Kriek available in the US on the East Coast. His Kriek is the best lambic beer I've had. Cheers, CR Return to table of contents
Date: Mon, 06 Jul 92 14:57 From: sherpa2!CCASTELL.ELDEC%mailsrv2 at sunup.West.Sun.COM (CCASTELL) Subject: Re: Dave Miller's New Book Norm Hardy asks about Miller's new book, "Brewing the World's Great Beers". I've had my copy for almost a week, but haven't had time to do any serious reading. I've been too busy brewing to have time for reading.:-) The book seems very approachable, in contrast to his earlier book. He makes it very easy for the novice to get started. The recipes start as all-extract using dry yeast. They become extract with specialty grains and liquid yeast, partial mash/extract/liquid yeast, and finally all-grain/liquid yeast. Most of the recipes are shown in all forms. The book also covers such topics as wort chillers, kegging, filters, and counter-pressure bottle fillers. On the down side, the recipes call for specific yeasts, but there is no discussion (that I've encountered yet) on what to expect from various strains. That shouldn't be too much of a problem, since that information is available from Zymurgy (and was also covered in HBD #742 by Daniel L. Krus), but its always nice when somebody includes everything you ever really need in a single book. An advanced brewer may find some of the discussions superficial, since Miller doesn't go into the chemistry that you'll find in his early book (or many of the technical books available). I would recommend the book to novice and intermediate brewers because of the breadth of information, put together in a readable format. Happy reading. Charles Castellow Return to table of contents
