Considering the bricks all around and the crucible are red hot, I would suspect the efficiency is far worse than that. > 2. Jack's setup is either lower in heat output or heat efficiency than a regular brewing setup. Of course, I realize that these numbers were just quoted quickly by Jack and may not be his true numbers. This is especially true since Jack also states that his setup will "boil 14 gallons of wort furiously". Don't look at me, I'm just doing the numbers :-) You can only use the number you have but here is another one that should help a bit. The furnace uses about 75 cuft of gas per hour, which comes out to about 25,000 BTU's in 20 minutes with the gas we get here. That compares to 14 cuft for my stove burner and 36 cuft for the water heater. Hmmm.... seems like I already knew the number but didn't know I knew it. >From: jdsgeoac at osg.saic.com (Karen Jdsgeoac Hyrum GEOACOUSTIC) >Subject: CO2 Cylinder filling and gas >I just had my CO2 cylinder refilled for the second time and I think I was ripped off. To 'fill' my cylinder the people connected my small tank to their big tank for about 30 sec and handed it back to me. This was done at a bar. They did not weigh my my tank or use any pump to transfer the CO2. I think all I got was about 875 psi of gas, but not a full 10 lb CO2 tank. Why think, just weigh it. A full 10 lb tank should contain 10 lbs of liquid CO2 and the empty weight of the tank is stamped on the outside somewhere. js Return to table of contents
Date: Thu, 22 Jul 1993 10:57:55 -0300 From: Ed Hitchcock <ECH at ac.dal.ca> Subject: Brewcap / Spelt Since Mr. Baughman mentioned his Brewcap, I thought I'd ask a question or three about it. First, there are two holes, one larger than the other. The larger hole fits a siphon hose, airlock, or whatever. What, exactly, fits in the smaller opening, or does the smaller oppening fit into a sphon hose? What sort of clamp do you use to hold it on, just a plastic strap? A pipe clamp? And thirdly, is the material of the Brewcap completely inert in beer? I appologize if these questions sound ignorant, but the local brewshops sell the Brewcaps under the assumption that they are simply for racking upright carboys (ie stick racking tube in short wider hole, blow into tall thinner hole to start the siphon). On another note, I was in a bulk store yesterday and noticed what looked like flaked wheat, but the bag was labelled "Spelt, no wheat". The TerriblyUnhelpfulShopkeeper Explained to me that it was "Spelt, it's not wheat". Thanks. When pressed further, she said it was a grain "as old as time...Biblical times...". Thanks again. I looked it up later, and it IS in fact a wheat, _Triticum spelta_, used mainly for livestock feed. Of course, at the bulk store the labell extolled the virtues of the proteins in Spelt ad nauseum. Anyway, has anyone used spelt (flaked or otherwise) in brewing? If not, would anyone like to know the results of a side-by-side Wit brew-off between regular flaked wheat and spelt? ed ____________ Ed Hitchcock/Dept of Anatomy & Neurobiology/Dalhousie University/Halifax NS ech at ac.dal.ca +-----------------------------------------+ | Never trust a statement that begins: | | "I'm not racist, but..." | +-----------------------------------------+ Diversity in all things.

Date: Thu, 22 Jul 1993 10:31:46 -0700 (PDT) From: gummitch at techbook.com (Jeff Frane) Subject: Dry-Hopping, etc. etc. etc. The Tumbleweed Report: The thing I love about this, Kinney, is that you are actively disproving the central theme of the brewpub explosion -- "you have to spend a lot of money on fancy stainless steel equipment, brew boring beer, or forget it." To avoid libel suits, we will call this the "California Brewpub Theorem", which *requires* startup costs of about $500,000 to $750,000. (The Hart Brewery, which makes Pyramid ales, was capitalized in about 1984 for $20,000; there is very little that has changed since then for someone willing to put in some work.)

So, it's 42 pages of real information; compare with the most recent issue of Zymurgy, which is a real embarrassment: what little editorial matter there is is almost indistinguishable from the vast amounts of advertising (including the AHA's own catalog stuffed in there), and most of what passes for editorial is composed of (a) self-promotion and (b) lists, lists and more lists. > From: jeff at rdii.com (Jeff Cook) > Subject: Belgian yeast strains > > A friend of my brought back two Belgian beers from a trip to Europe. > One of the bottles is labeled Maredsous, the other is labeled Lucifer. > > Also, does anyone know anything about either of these beers?

The Maredsous is unremarkable, and I don't remember much about it; the Lucifer is a sort of Duvel knock-off, inferior to the original but still pretty good. Hey, the trick with those yeast strains is to culture them out, then add them to a small amount of 1.030, unhopped wort. You will be able to tell *a lot* about the flavor profile by tasting the resulting beer, and you can answer your own question about whether it seems suitable for brewing. > > From: "Thomas J.

The amount of time you dry-hop is dependent on how much hop character you want to draw off. Seven days really isn't enough, and two weeks is, IMO, a minimum to actually express some hop character. My own experience, going back six or seven years of dry-hopping, is that six weeks is optimal for a really distinctive dry-hopped beer, but that's only a recommendation for kegged beers. (It also happens to gibe with the recommendation of the brewers at Sierra Nevada for their Celebration Ale.) Leave the hops in until you bottle. > > > Date: Wed, 21 Jul 93 14:49:32 EDT > > This is not a question about Home brew but about HOMEBREW Digest. > > I am new to the HOMEBREW Digest and the internet.

Pyeatt) Subject: Degrees of Extract Don Doyle writes: > As a real example, I brewed 11gals with 26.5 lbs of grains and got > a 1.065. What extraction am I getting and is it good? Well, plugging the numbers into the equation, DE = 1.065 * 11 / 26.5 = .44 or 44 degrees of extract. From this, I would guess that you added some malt syrup or adjunct. Most malts are "theoretically" capable of producing about 35 degrees of extract. I usually get around 32 degrees, which is pretty good. The degree of extract tells you how effecient your mash was. If you are getting less than 30 degrees, there is room for improvement in your technique. ( My own personal opinion. ) Larry D.

Is the stuff impossible to rinse off?? What is >the networks accepted method for using this stuff? The reason that often iodophor packages often advertise that iodophor does not need to be rinsed is because some brewer's water has bacterial problems and rinsing with the water can re-introduce bacteria. I've never had problems with using hot, Chicago tapwater for rinsing, even in the summer (when everything is more microbiologically active -- that's why the water supply often has increased levels of chlorine added in the summertime). I'm quite confident that your problem was not from the iodophor, rather that the medicinal flavor/aroma came from one of the following sources (in order of probability): 1. yeast -- I've noticed that some dry yeasts, if not stored in a fridge, after while, will produce increased levels of phenolics. Perhaps this is because there was some more hearty wild yeast in the dry yeast or maybe it's a result of poor storage. Other dry yeasts, even when stored properly produce phenolics. 2. airbourne wild yeast infection -- it seems as if your sanitation technique is good -- could some wild yeast have gotten in via the air? Could your problem correlate with the warmer weather, when the air is more active microbiologically? 3. wild yeast infection from the water -- maybe you do have a problem with your rinse water... the solution would be to boil the rinse water or to air dry the iodophor-sanitized equipment. ****************** Don says he got 11 gallons of 1.065 wort from 26.5 lbs of grain and wants to know what his extraction rate is and is it good. Well, the maximum extraction varies depending on the type of grain, but you got 65 "points" and this translates to: 65*11/26.5 = 26.98 or basically 27 points-per-pound-per-gallon, which is quite good for most types of base grain. Some get as much as 30 or even 31 points (Miller does this partly because he re-circulates the runoff an awful lot and this not only gives him great numbers, but also it has been reported that Dave's beer is on the astringent side). ******************** Jeff writes: >A friend of my brought back two Belgian beers from a trip to Europe. >One of the bottles is labeled Maredsous, the other is labeled Lucifer. >From the sediment of each bottle I have plated out a yeast culture. Does >anyone know anything about either of these yeast strains. Will either >of these yeast strains be suitable for fermentation, or are they just >used for bottle conditioning? I don't know whether Lucifer is bottled with the fermentation yeast, but my guess on the Maredsous is that it is a bottling yeast. My reason for this assertion is that Maredsous is made by the same brewery as Duvel (note the bottle shape is distinctive and the same as Duvel) and I've read (here in the HBD) that Duvel is packaged with a bottling yeast and not the fermentation yeast. Oh, yes, I recall the brewery -- it's the Moortgat Brewery in Breendonk, if memory serves correctly. >Also, does anyone know anything about either of these beers? I cannot read >either label, and I do not know what style either of these beers are. Maredsous is an Abbey ale, and it comes in four types which, I believe, are associated with the Belgian degrees of the OG. If memory serves, they are 4, 6, 8 and 10. I've had only two and the numbers were NOT on the label (stupid US laws!). One had a Gold and Black label and the other had a Gold and Green label. I'd be interested in the colors of your label and the number on the bottle, if you could send me email or post it. 4 Belgian degrees is 1040, 6 is 1060, etc. I have not tried Lucifer, but have read about it in Jackson's pocket guide, big book (I forget the name too) and the Great Beers of Belgium book. Basically, it is a beer of the type that was originated in the beer Duvel. Duvel means devil and therefore virtually all the breweries that imitated this beer have chosen names that are associated with the devil: Lucifer, Satan, etc. *************************** JC writes: >BTW, I don't think Foxx accepts CC orders, nor does BCI. My first order Hmmm, from Satan to JC... anyway, Foxx does now accept CC orders. This is a pretty recent change. *************************** John writes: >I've heard in the past that some larger breweries were jumping on the micro >bandwagon by selling beers that looked the part.

Pete's Wicked Ale and their other beers are contract brewed by the August Schell Brewing Company in New Ulm, Minn. I don't know how big it is, but it's no industrial megabrewer. ********************************** Thomas writes: >I'm dry hopping my steam beer and was wondering how long is too long to dry >hop? I moved the beer to the secondary and added the hops on Sunday, planning >to go on vacation Tuesday.

Is this too long? >I've read that dry hopping is best done the last 5 to 7 days. I could remove >the hops on Friday but I wouldn't be bottling for a least a week after that. >Any suggestions would be appreciated. Leave the hops till you can bottle. The reason I posted that "you should not dryhop longer than 7 to 10 days" is that, empirically, I've found, that more than 10 days gives less hop bouquet than 10 days. This is for 65F or so. At cooler temperatures (although I haven't done this -- this is based upon what I've read about commercial breweries procedures), like 50F or so, two weeks seems to be the consensus. Al.

Date: Thu, 22 Jul 93 17:55:19 EDT From: roberts735 at aol.com Subject: Keg Parts I have purchased a pair of old but clean Firestone 3-gallon kegs similar to Cornelius. In the process of replacing the gasket for the lid, which is screw-down, and circular, not spring-clamp and semi-oval, I discovered the regularly mentioned suppliers do not carry the part. The Firestone keg was manufactured by a company now called Spartansberg Steel Company in Spartansberg, South Carolina. They do not have parts, and say the keg is very old. Help... does anyone know a source for the gaskets, or a functional substitute? The other fittings are standard pin-lock, and the kegs are too fresh to dispose of, even if they are old...

I was curious about Jackson's series Beerhunter, so I called my cable company and asked for the Discovery Channel's phone number and was given: 1-301-986-0444 x5298, this was to put me in touch with the people who would tell me when this delightfully sounding show would next appear on this channel. I was asked by a recorded voice to leave a message and my phone number and was told I was to be called back. I was. The next day I found on my machine a message from the Discovery Channel saying, "The Beerhunter will not be running anytime in the future on The Discovery Channel." They did not give any justification for this decision. I was, however, given the name and number of the distributor, "Channel 4 TV" of London. This number is 011-44-71-631-4444.

Date: Fri, 23 Jul 93 08:54 CDT From: arf at genesis.mcs.com (Jack Schmidling) Subject: Crushoff in Portland There have been rumors that a certain grainmill producer plans on conducting a mill evaluation of sorts in Portland. My first reaction was to grab a new MALTMILL and head for Portland to defend the fort. This was based on information he is promulgating that portrays the MM as no better then the Corona. Turns out, all his hype is based on unscientific tests that seem to prove nothing. As it is unlikely that the proper equipment will be available in Portland, I decided it was not worth the expense and hassle just to prove what most of us already know. To avoid the feeling of fiddling while Rome is burning, I dropped some samples of milled product off at Siebel Institute for an unbiased evaluation of the grist of the MALTMILL and the other mill. The results confirmed what George Fix reported a year ago and experience on over a thousand units has demonstrated. The adjustable MM provides a grist that is comparable to a multistage commercial mill. The fixed MM provides a very satisfactory grist but is a bit coarser and somewhat grain dependant. The other mill, when properly adjusted provides a sieve analysis similar to a fixed MM on paper but visual analysis shows more husk damage. Unfortunately, the sieve analysis can not tell the difference between small husk particles and similar sized malt particles that pass through a sieve. It was designed to test roller mills and not grinders or hybrids such as the other mill. For those going to Portland, there will be a MM on display in the TKO Software booth and Tom Nelson will have flyers and data sheets to hand out. Feel free to fondle it. I am confident you will conclude that there is far more than the nuances of grist variation involved in selecting a grain mill. js Return to table of contents

When I first started brewing I used corn sugar which worked OK, but then having decided to brew "all malt" only I switched to gyle which was also good, but less convenient to use. I now use only dried malt extract for priming. For English or Scottish style ales I use 1.25 cups light dry extract dissolved in 2 pints water, boiled for 10 minutes, cooled, & poured into my sanitized "bottling bin" (a plastic fermentor with spigot. I then siphon the beer from my glass carboy (which allows good mixing without much oxygenation), allow it to stand for about 15 minutes while arranging bottles, and then bottle. For American style ales, California Common beer, or lagers I use 1.33 cups of malt extract which results in slightly higher carbonation. No more gushers as I had with corn sugar.

Date: Fri, 23 Jul 93 11:06:23 PDT From: Mark Garetz <mgaretz at hoptech.com> Subject: CO2, Old book, Portland Several posts have appeared recently about filling CO2 cylinders: To the poster that got it filled at the bar, yes you got ripped off. Go to a welding supply, fire ext. supply or look in the YP under Carbon Dioxide. It does pay to shop around as prices vary. When I bought my second CO2 tank, I asked if it was possible to fill an empty tank from a full one. Technically, it will work, but it was explained to me as being very dangerous! This was because the tank being filled will heat up and explode if it is done too fast and without the proper equipment. In fact, most of the welding gas suppliers in my area don't actually fill tanks anymore, but exchange them. The filling is done in a central facility. Bottom line: Don't mess with it. It can be fatal to you and your neighbors! On another topic, I was at the UC Davis library's "brewing room" recently and I came across a very old book by E. R. Southby called "Practical Brewing". It had a lot of interesting information on hops and hopping rates (the only stuff I copied, naturally) but the book had no date on it. The library's computer (actually the Melvyl system) also had no date for the book or the author. The book was published in England, I would guess around 1890, but I like to know for sure. Does anybody have any clues? Southby had died a few years previous to this edition (the third). If anyone has any info on Southby or the book, I would appreciate it. There were many other old books there and I copied the hops data out of three. I'll summarize and post soon. You'll find it very interesting. Related to my trip to Davis, I also got some better info on the "hop storage curve". There were two good articles and as soon as I've had a chance to digest them, I'll post an update to my storage post. Lastly, I'll be in Portland for the Oregon Brewer's Festival (but not the AHA event) at the Hopunion booth if anyone wants to drop by and chat or say howdy. How many of us will be there on the weekend? Should we do a pub crawl on Friday night maybe? Mark Return to table of contents

Date: Fri, 23 Jul 93 13:58:22 PDT From: bill at oilsystems.com (Bill Vaughan) Subject: Blowoff, Iodophor, Sterilizing bottles Here are a few data points to add to the debates: Blowoff -- fortuitously, my last batch of "plain jane" got split into its carboys unevenly. Consequently, one blew off and one didn't. Of course, the best test would have been if I had kegged both carboys or bottled both, but in fact I kegged the one that did blow off and bottled the other. Anyhow, at kegging/bottling time, I could definitely taste the difference between the with-blowoff and without-blowoff carboys. The without-blowoff carboy had a tad more bitterness and was slightly "harsher." I have never done this kind of direct comparison before and frankly did not expect to taste any difference at all. Surprise. The only problem is that I just bought 2 more acid carboys (7-gal) and I can't ever fill them enough to get a blowoff. Maybe I shall use water carboys for my delicately- flavored brews and acid carboys for the chewy dark ales. I dunno. Iodophor -- I have been using iodophor (BTF, I think) to sterilize my kegs. I use the recommended amount for the recommended time and air-dry. Then I give the keg the sniff test. If I smell ANY iodine, I rinse the keg with boiling water. So far I have ALWAYS smelled iodine. I am not about to buy another bottle of iodophor. To me, the slightest iodine flavor would spoil the batch and I hate to throw out 5 gal. I suspect that boiling water alone may work -- or else I shall go back to weak clorox followed by boiling water rinse. Let's face it -- kegs aren't that expensive. If I get pinholes in the s/s after, say, 5 years, the keg has cost me maybe 5 bucks a year. (Of course, if it's only ONE year, I'd feel different.) Sterilizing bottles -- I have always sterilized my bottles in the dishwasher. I clean the bottles thoroughly with TSP, in the sink, scrub them and rinse them carefully. Then they go in the dishwasher for a full wash cycle with NO detergent, and a HEAT DRY (not air dry) cycle. Naturally I prepare the dishwasher first by cleaning all the guck out of it and running it once while empty. Bottom line -- Mary and I have never had a bad batch that could be attributed to unsterile bottles. (I.e. either the whole batch was uniformly bad or uniformly good. We did have an episode where our yeast starters got infected once.) I have mild asthma and Mary has it bad. We have to be careful about sulfites. All you homebrewers, please remember that Campden tablets and bisulfite sterilants can make your homebrew toxic to those with respiratory problems. BTW, whenever I have a chance I sterilize with boiling water in lieu of chlorine. This only works for small stuff like airlocks but is quite effective and there is no danger of chlorophenol or iodine contamination. I think it is just common sense to eschew toxic substances wherever possible. - --Bill Return to table of contents

I would be willing to bet that the stuff growing on your parents' farm are Clusters in some form or other. It's amazing to me that some people are still brewing with these hops, which used to be considered high alpha -- they have no other redeeming quality as far as I can tell. The British referred to American hops as being "catty", which meant nothing to me until I smelled some Clusters: they smelled just like a catbox. I have some terrific old photographs, courtesy of the Oregon Historical Society, of old hop farming, some dating back to the turn of the century, and some from the period in which your old hop farmer quit. During the 20s-40s (judging from the clothing), at least some of the Oregon hop growers were training their hops along low-lying strings, - --Jeff Return to table of contents
Date: Sat, 24 Jul 1993 03:12:27 -0400 (EDT) From: waltman at BIX.com Subject: What is a microbrewery? Maybe we should come up with terminology describing individual beers by the size of the batch. (My understanding that the legal definitions of microbreweries {for tax purposes}are based on the aggregate annual production of the entire brewery.) I think this would help differentiate those beers that are brewed in megabrewery size batches a few times a year as opposed to those that are brewed more often in smaller batches. This is not to imply that smaller is better, but I think it could make for more rational comparisions. Just my $.02 worth.

They take credit cards for orders-so it looks like you could just call. Its 24$/yr for six issues. You shoudl be able to find it in your local supplier--and the one around here discounted the first isue since the second issue is now out. The first issue had 42 pages of text--a fair amount of which was articles: 1)Facftors Affecting Hop Quality,...and Brewers Preference. 2)Belgian Malts--some pratical observations 3) Reinheitsgebot and the fifth ingredient 4) The Troubleshooter--an advice column--w/o the Hbd 5) Brewing in styles--a changing discussion on styles and how to brew them 6) Thinking about recpe formulation 7) Spreadsheet recipe design 8) And a bunch of assorted smaller depts--a book review, and a few others. Overall I think the first effort was quite good. In fact a few of the articles mentioned above were written by HBD'ers with extensive knowledge.
