These files have ".Z" as the filename extension. This naming convention indicates that the files were compressed with compress (that's the name of the program). If you cannot find a version of compress for your PC, let ftp decompress the files during downloading. When you enter your "get" command, leave the .Z off the filename. The file will be decompressed auto- matically. Rolland Everitt af509 at osfn.rhilinet.gov Return to table of contents
Date: Mon, 27 Nov 1995 20:17:18 -0500 (EST) From: Eric Marzewski <emarzews at nova.umuc.edu> Subject: Inverted Carboy Fertmenter Products Eh People, I received a couple of responses on the carboys products that allow you to ferment/ turn your carboy into a conical fermenter. They were both negative... summary: -had to rack yeast out several times, still got more yeast then wanted in final transfer, clogged tubes... even after several yeast removals. Overall, easier to rack off with siphon or slight CO2 pressure/closed system into CO2- I've never tried them, but still it seems like a possible way to store/propagate yeast by having an active culture for ale for a short time as it ferments and lagers for months of brewing if you have a chest freezer or real cool basement. They all said yeast was "rackable". What if a club, group of friends or person wanted to get yeast cultures for pitching all off one culture/step up. I am not accounting that you could easily do it at high krausen or an optimal time to repitch a culture. If there's anymore thoughs, I'd be glad to summarize them for the digest.

Kutskill" <75233.500 at compuserve.com> Subject: Bread yeast and beer Here's a twist on the ol' phrase _is my beer ruined?_ I have a friend (honestly, it is a friend and not me) who thought he had a dead packet of dried yeast and used regular bread yeast to ferment his first batch of homebrew. Is my friend's beer ruined? Never heard of this before--wondering if anyone has any information about the taste characteristics of bread yeast (red star brand). Looking forward to tasting a slice of it when it is done :-). Kevin A. Kutskill ("Dr. Rottguts") Clinton Township, MI "A homebrew a day keeps the doctor happy" Return to table of contents

Date: Tue, 28 Nov 1995 06:25:51 -0500 From: Mark Redman <redman at vivid.net> Subject: for_publication_only I have been an all-grain brewer for a couple of years, and still bottle with a corn sugar prime. I recently entered a brewing contest, and although I won a couple of third place awards, I was counted off for a "winey" taste attributed to corn sugar. I want to start priming with either malt extract or wort saved from brew day, and would like some feedback on a couple of areas. What amount of extract is sufficient for adequate carbonation? I brew a lot of German Pilsners so I would like a good deal of carbonation. How much longer does it take to carbonate using extract? Remember, I am carbonating at 50 degrees F. What are the advantages of krausening with wort saved from brew day, and what amount if sufficient for proper carbonation? Any feedback would be appreciated. Return to table of contents
Date: Tue, 28 Nov 1995 04:50:07 -0700 From: wa5dxp at mail.sstar.com (Jim Overstreet) Subject: Disturbing Pub Trend In the New Orleans area, there has been a very disturbing and I think very negative trend at places serving "craft beers". Over the last several months, it appears most of the pubs have switched over to an "air delivery" system of pushing beer, in place of the old CO2 method. I first noticed this at my regular pubs all throughout the New Orleans area and surrounding towns. I was told a large percentage of the local establishments have switched over to this system. You first notice the difference by the sorry "taste" of the beer, it tastes flat and flavorless or "cardboardy". (I had originally included specific names in this post, and edited them out in case the owners have that infamous Jim Koch disease.) I wonder if any other cities have fallen for this "bill of goods" and are switching over to this nefarious system? Could this be what is responsible for the HBD threads citing the lack of flavor at the once-great micro's? By the way, the new Acadian Brewery Brewpub is now open, but not selling their own beers, as the brewhouse is not online yet. I have been assured by the principals there they will NEVER go to an air delivery system. They are located on Carrolton Ave. one block East of Canal St, across from the Venezia's Italian Restaurant. They claim they will sell only fresh product. They have Abita, Dixie, Vermillion, Rickenjacks, Guinness on tap, and a good selection of imported beers. Brewmaster Doug Lindley says he hopes to have brewery online by New Years with a Pils as the initial offering. They will be brewing in 30 bbl batches. Is this "Air Delivery System" a local or nationwide trend? Return to table of contents
Date: Tue, 28 Nov 1995 21:55:40 +1000 From: merino at cynergy.com.au (Merino Lithographics) Subject: Caramel Andy Walsh posted >Just what is caramel anyway? It starts off as sucrose, but what does >it end up as? It is not very soluble in water (unlike candi sugar, or >sucrose), so I imagine it turns into something quite different by the >cooking process. As yeast is only capable of fermenting very basic sugars, I >am more than a little concerned that caramel is unfermentable by yeast. One >thing I do not want is sweet, sickly, caramel beer. Caramelization is a general term for one of the three non-enzymic browing reactions in food. One other NEB reaction we are familiar with is the Maillard or browning reaction which contributes to flavour, colour and aroma in the boil. Maillard reactions form between protein peptide/amino acids and simple sugars Caramel is formed a number of ways. A)In malting and brewing caramel is formed by the reaction of sugars with *each other* in the presence of heat with little or no water. The result is non fermentable "reducing sugars" and fermentable sugars. pH has some influence on the outcome mixture but I've not found what. 1/ The maltster takes a fully modified barley and steeps it in water and heats it to sachrification temperatures under pressure to prevent drying, literaly mashing it in its husk! The malt is then heated to 120C+ to caramelise the sugar mix. Different temperatures give different results. This "Crystal Malt" is a controlled way of producing caramel sweetness, aroma and copper colour in beer. It comes in various degrees Lovibond. 2/ In the kettle there is a boundary layer of fluid adhering to the walls. If the boil is not "rolling" (convecting) enough to break that layer into turbulent flow and maintain an even temperature of about 100C, the layer will overheat. This is because heat is carried through water mostly by convection. The heat conductivity of still water is 1/70th that of steel. The boundary layer boils off its water leaving sugars to be caramelized. The sugars have much less heat conductivity (1/7th)than even water, so they overheat in turn. These scorched products become a astringent carbonised mess, a little like burnt toast. This is uncontrolled caramelization! Without Turbulent Boil heat | kettle |boundary| wort source | wall |layer | boiling ~800C -> | ~230C-> | 100C->| 100C Caramel ^here With Turbulent Boil heat | kettle | wort source | wall | boiling 800C-> | ~110C-> | 100C Solutions to this problem are steam jacketed heat source at 170C, superheated steam injection, mechanical stirring, or changing the kettle geometry. If the heated surface of the kettle is an inverted cone (opposite to a fermenter) or a simple 45 degree slope, then the rising bubbles join others above them and then the bigger bubbles rise faster creating a turbulent current across the heated surface. This design is used commercially to create "rolling" boils with less energy input. B)Caramel as a commercial colourant is prepared by heating *sugars* (plural) under pressure in the presence of ammonia. It is dissolved as a powder before fermentation. It is widly used to colour whiskey. During fermentation caramel will yield an extract of about 66% (De Clerk)and will contribute to sweet palate and aroma. Because it has low flavour and colour thresholds, I believe it is best created outside the mash tun and kettle. Colouring manufacturers and maltsters (crystal malt and cara-pils are caramelised) use much more controlled conditions and produce a more consistent smoother result. Andy's experiments will probably produce a lighter result than malt. I imagine that a sugar filled container inside a water half-filled pressure cooker would produce a consistent caramelization temperature. Time and the sugar mix will be useful variables, a little acetic acid will smooth it I think. Charlie (Brisbane, Australia) Return to table of contents
Date: Tue, 28 Nov 1995 07:14:08 -0500 (EST) From: FLATTER at RoseVC.Rose-Hulman.Edu Subject: Brewferm Ambiorix information Yesterday I started a batch of Ambiorix from a Brewferm extract kit. Magazine advertisements say it tastes like the commercial beer of the same name, but I have never had the pleasure. I've enjoyed all the other Brewferm kits so far, and I found it at a good price. I'd just like a better idea of what to expect. Can anyone out there provide tasting notes, AHA style, or other notes? I already have projected color, OG/FG, and %alc from the add.

Date: Tue, 28 Nov 1995 13:21:53 +0000 (GMT) From: Delano Dugarm 36478 <ADUGARM at worldbank.org> Subject: Celebration Ale - IPA recipe Tim Fields writes asking about Celebration Ale availability on the East Coast. When I first heard about this I called Sierra Nevada and learned that due to excess demand for their regular line and delays in a major expansion, they were cutting back on production of seasonals, and restricting distribution of them. Bummer. All is not lost, though. In the DC area there is Old Dominion's Tupper's Hop Pocket, and I've heard good things about Catamount's Christmas ale. But why buy when you can brew it yourself? Below is the latest iteration of my IPA, with which I've won at least a dozen ribbons and a couple of BOS. If I can do this well with my sloppy techniques and aged zapap lauter tun, think what you can do! (Note: the grain bill assumes 25 points per pound.) Columbian IPA Grain Bill 12 lbs Briess 2 row 1 lb DWC Munich 1 lb DWC Caravienne 1/2 lb Gambrinus Honey Malt 1/2 lb DWC Biscuit Mashed at 158 for 60 min., mashout at 168 for 10 min. Hops 2 oz Columbus (9.5%) 60 min. .5 oz Columbus (9.5%) 15 min. .5 oz Cascade (5.5%) 15 min. .5 oz Columbus (9.5%) 0 min. .5 oz Cascade (5.5%) 0 min. 1 oz Cascade (5.5%) dry hop Ferment with WYeast 1056 at 60 F (ambient) OG 1064 FG 1018 Notes: 1) Be sure to aerate the wort well. 2) Columbus can be replaced by Centennial, but Columbus gives an especially grotesque, tasty oily hoppiness. I guess you could use Chinook, but I've hardly used that hop. If you keg, consider cask hopping instead of dry hopping. 3) I've used other ale yeasts, but have not been as happy as with Chico yeast: the fermentation products of other yeasts interfere with the hops hammering your tastebuds. I ferment cool to keep the beer as clean tasting as possible. Al Korzonas writes that this yeast tends to shut down when cooled below 60 F. This has not been my experience, but I'm measuring the ambient temperature, not the temperature of the fermenting wort.

Date: Tue, 28 Nov 1995 09:32:06 -0500 (EST) From: Kostas Daskalakis <KDaskalakis at rdc.noaa.gov> Subject: PET bottles, O2 permeability I would also agree with Philip Gravel's and Robert Hett's explanation for oxygen diffusion into PET bottles. RH also attempted to give an answer about the kinetics. To my opinion this will mainly depend on the thickness, type, and degree of polymerization of the material and O2 pressure differential. Years ago I looked at the diffusion rate of O2 into deoxygenated, distilled water inside low-density polyethylene 100 ml (thin- wall) bottles, used by many laboratories. To my surprise water was fully saturated with O2 in just 2 days. While thicker walls will decrease the diffusion rate, I just don't want to have this headache. Kostas Return to table of contents

There is some probability that an oxygen molecule will cross the PET barrier, either going in or going out. Since there is more oxygen outside the bottle than inside the bottle, more molecules go in. Oxygen will diffuse in until the probability of an oxygen molecule entering the bottle equals the probability of an oxygen molecule leaving the bottle. This argument is equivalent to the partial pressure argument. Bob McCowan bob.mccowan at cfrp.varian.com Return to table of contents

Just because it's legal don't make it right. Seriously, I don't know all the details on Maytag's and Koch's assorted litigations, but I do know that either through carelessness or bad PR (same thing?), I have gotten the very clear impression that Jim Koch cares more about profits than beer. Of course, if you don't sell your beer, you can't make a living making it. Maytag knows that. And, maybe he and Koch are more alike than we think. Nonetheless, I get the distinct impression, from tasting, marketing, and new reports, that Maytag is _making money in order to make beer_, whereas Koch is _making beer in order to make money_. How is this going to help you on your next batch of homebrew? I'm not sure, maybe just be glad that a few extra pennies per bottle isn't going to bother you when you're formulating your next recipe. How will this help your beermaking? Well, I think you'll get better beer, at least in the long run, from someone who puts quality on a higher priority than profits. And, if my impressions are wrong about Maytag or Koch, maybe posting this will allow someone the chance to correct me, and improve all our lives. Sorry this is so long, -Russell ps.

All they have to do is buy it right and use it right and it is dirt cheap. First, don't buy it in a homebrew store. If you have a business, or know anyone who does, buy it by the gallon from a restaurant or bar supply company. It costs me $22 per gallon, or if you can go together with some other people, a case of 6 gallons will cost about $15 per gallon. So much for initial high cost. OK, so you can't buy it by the gallon. It is still cheap to use if you use it right. I use 6cc per gallon. I mix up 5 gallons, which uses 30 cc or about 2 oz. I use it and then pour it back into a corny keg for storage. About every 3 months or so, I add another 6 cc and top it up with a gallon of water to make up for inevitable losses. Another reader Emailed me how he uses several corny kegs in series and transfers sterile water and iodophor in a series so he puts a clean unsanitary keg at the end of the line, forces the sterile water from the first keg into the second keg which holds iodophor, which forces the iodophor into the empty keg. He then takes the first keg off the line and it is empty and purged with CO2. Not a drop of iodophor lost. If you keep an iodophor solution sealed up in a corny keg, it will last indefinitely. dion - -- Dion Hollenbeck (619)597-7080x119 Email: hollen at vigra.com Senior Software Engineer Vigra, Inc.

Date: Tue, 28 Nov 1995 10:58:42 -0500 (EST) From: Scott Bickham <bickham at dave.nrl.navy.mil> Subject: Spirit of Belgium announcement Announcing the second Spirit of Belgium Homebrew Competition to be held in Arlington, Virginia, February 10, 1996 This is your official invitation to participate in the Spirit of Belgium Homebrew Competition. In November of 1994, BURP was proud to sponsor the first homebrew competition that focused entirely on Belgian beer styles. This competition was held in conjunction with a conference that provided technical coverage of Belgian beer styles and how to brew them, as well as giving the opportunity for participants to experience the rich cultural history associated with Belgian beer and brewing. Although the conference will not be held this year, we encourage you to keep the Spirit of Belgium alive by participating as an entrant, judge or steward in this BJCP recognized competition. The Spirit of Belgium Homebrew Competition offers entrants a chance to compete with other homebrewers of Belgian-style beers and to gain some valuable feedback from panels consisting of judges in the Beer Judge Certification Program (BJCP). As many of you know, the quality of the judging varies widely in the Belgian categories of local, regional and even national homebrew competitions. The goal of this special competition is to provide an opportunity for homebrewer to have their beers evaluated by judges who are not only ranked within the BJCP, but also recognized for their knowledge of Belgian beer styles. The judging will be hard work, so we have planned a few activities to entice BURP members and out of town judges to participate. On the Friday evening before the competition, BJCP National judge Tim Artz will conduct a tasting of commercially available Belgian beers representing several different styles. The competition will begin on Saturday morning and conclude with the Best of Show judging in the late afternoon. All participants and BURP members are then invited to attend a banquet and awards ceremony that will feature authentic Belgian cuisine that will be prepared (and consumed) with Belgian brews. There are a limited number of spaces for both the tasting and the banquet, so reservations will be accepted on a first come, first served basis. Finally, those with the energy will easily to able to find a BURP member to guide them to their favorite brewpub or beer bar in the Arlington/Washington area. More details about the competition and banquet will be given upon registration. For entry forms or registration information (specify which), send e-mail to Scott Bickham at bickham at dave.nrl.navy.mil. Return to table of contents

Is propane always unsafe? Seems to me that many rural houses cook with propane and the inhabitants are not dying of CO poisoning. It seems to me that the quality of the burn (complete combustion with sufficient oxygen to produse CO2 rather than CO) is the issue, and I wouldn't count on a cajun cooker being safe with NG. I use a 35 kBTU/Hr ring-type cooker, which gives me a nice blue flame with yellow tips. The flame is easy to control and gives me a clean blue flame with no soot at any pressure. It's a brinkman Country Cooker that I've had for many years, don't know if they still make it. I use it in the garage with the door open. We're going to put in a CO detector in our house, and I'll fire up the cooker near the CO detector and see if there's a CO problem with it.

Date: Tue, 28 Nov 95 13:37:52 -0500 From: r-brodeur at ds.mc.ti.com (Russ Brodeur) Subject: DMS Production One of the appealing characteristics of continental lagers, IMHO, is the "corny" or "lagery" flavors. I believe they are caused by DMS levels 2-3x the taste threshold. I find this flavor all but absent from domestic lagers, including micro-, pico-, etc brews, although I think I can detect some in Miller's products. Anyhow, I would like to brew lagers with this characteristic lager flavor, not just hops & malt. I read in G. Fix's book that wort cooling rate plays an important role in residual DMS levels, with increased cooling rate corresponding to decreased DMS. Conventional wisdom seems to lean towards rapid cooling, with CF and immersion chillers. This reduces problems with bacterial contamination and gives a better cold break. Is there a temperature range where DMS production is high, yet bacterial contamination etc can still be avoided???? I am toying with the idea of letting the hot wort sit for some period of time (1/2 h??) before chilling. This way, boiling won't remove DMS from the wort. Any comments/ suggestions?? Regards.

I aerate by doing the carboy shake. I have a solid gum stopper that I use to plug the carboy. After bleaching the stopper, I rinsed it under hot water, put it in the neck of the carboy and plop! it went right in. I mean in. Floating on the wort. The hot water must have made the stopper more flexible. I racked that batch to another fermenter before I pitched the yeast. I then had a carboy with a stopper rolling around the bottom. Now I know that many of you recommend against rinsing with hot water, but I thought I was risking bacterial contamination, not stopper contamination! So does anyone know how to remove the $0.79 stopper without breaking the $20.00 carboy?. I use this carboy as my secondary. I have considered just sanitizing the carboy, stopper and all, and using it for my secondary anyway, but I am worried about what can be extracted out of a gum stopper by 3-5% ethanol. Am I worrying too much? Is My Carboy Ruined ? (IMCR?) Any help would be greatly appreciated.

Floating the Guiness on top of the Bass symbolizes the >Irish overcoming the English. Apparently, the color of the uniforms of the bri >tish troops occupying Northern Ireland are also black and tan. Anyhow, just a >little something to think about... :) The historical reference is not quite correct. It was indeed the color of the British soldiers' uniforms(black jacket, tan kilt) serving in Ireland but the period was around WWI just prior to Irish independence/partition. With the rest of the British empire entrenched in France, the quality of these troops was not high, and they (not surprisingly) have always been much maligned by the Irish. As regards the drink. Floating the Guinness on top of ale is to me a recent affectation. Where I grew up, industrial north of England, you would be laughed out of the pub if you asked the barman to float the Guinness. I have seen black and tan served as: Guinness and bitter or mild or brown ale or pale ale. The Guinness could be draft or bottled. Why bother? - well it was a slightly cheaper way of drinking Guinness, since the ale cost less than the stout. (it was definitely not a political statement) Regards... Pat O'H.

Date: Tue, 28 Nov 95 11:54:40 MST From: roberts at Rt66.com (Bird) Subject: Water chemistry problem Ok water gurus: I've finally figured out a solution (no pun) to a water problem that I've had ever since moving into my new house. The water is well water, fairly hard (10 - 11 grains per gallon ~= 180 ppm total hardness). I have not had it analyzed further to determine Ca, Mg Mn, SO4, CO3, etc., but I eventually will. The problem is that I was getting an astringent, bitter character over and beyond the normal, desired hop bitterness. I have finally tracked it down to the ph of the water. Because I obviously have a lot of CO3, the ph is running right at 8.5, way high. With my last batch, I adjusted the ph of the mash water down to 5.2, and the sparge water to 5.7 using lactic acid, and the extra bitter/astringent character is completely absent in the new beer. I suppose that the high ph was causing unacceptable amounts of tannens to be leached out during the mash/sparge. So, now that I know to adjust the ph, I'm trying to find a supplier of food-grade lactic acid (88% aqueous), with near-zero luck. My normal home brew supplier (The Alewife in Santa Fe, NM) carries small bottles (~200 ml) of the stuff, but I wish to purchase maybe a gallon. Does anybody out there know of a source?

Species names ending in myces are not all fungi. For example, most of the therapeutic antibiotics are produced by Actinomycetes, which include Actinomyces and and Streptomyces species. These are bacteria. Also noteworthy is the fact that myces is singular and mycetes is plural (like fish and fishes). Tracy in Vermont aquilla at salus.med.uvm.edu Return to table of contents

Howard" <102012.3350 at compuserve.com> Subject: Gas Burners While reading all the traffic on various fuels and burners, it occurred to me that a salvaged NG burner from a water heater might be the basis of a good high output cooker. It then occurred to me that since this is such a dandy idea, I'm probably not the first one to think of it. Does anyone have any experience with same? Two possible problems: A) It was designed to run wide open and might not work well at a lower flow rate after boil had been reached. B) Because the original unit was vented, clean burning (no CO) would have been a design issue only to the extent that it supported fuel efficiency. If this has already been beaten to death in past digests, please let me know. Gregg A. Howard 102012.3350 at compuserve.com Return to table of contents

I'm trying a remailer to see if it will get there. My name is Tim. I'm in Butte, Montana. I started brewing about 11 or 12 years ago but fell out of it for 6 or 7 years. The first and only book on homebrewing I used was Dave Lines. I re-read it over the holidays and still managed to distill some wisdom from it. I am an all-grain brewer, use liquid yeast, and keg. The last pack of Wyeast I bought (American Ale) lasted for 15 batches without going over 3 generations old, so I guess I'm frugal. {Unerstatement of the century 8-)} One of the latest experiments I've dreamed up is making a concentrated mild ale and diluting it to 10 gallons in the secondary. Has anyone tried this already. I don't forsee many problems from a late addition if I preboil and cool the dilution water beforehand. Hope this gets through!

Well, lemme tell ya, I was out in my favorite tavern the other night (Quencher's in Chicago) and had my friendly bartender give me a glass each of budwiser, miller, and old style. That's right, a blind taste test. Now I'm not sure whether I should be proud or ashamed, but I guessed all of them right the first time. I'll also admit that I wasn't entirely sure on the first sip whether he even poured 3 different beers. They really tasted indistinguishable to me, and one of my drinking buddies couldn't tell them apart at all. So I guess some of us can stoop to their level if we have to, and as always, no flames please: the remaining "beer" was disposed of properly...in the sink...
