---------------------------------------------------------------------- Date: 20 Jul 1993 13:42:51 -0500 From: Chris McDermott <mcdermott at draper.com> Subject: On sugars On sugars In HBD #1184 William A Kitch says: > Dark sucre-candi: Philip Seitz says as near as he can tell rock candy= > sucre-candi. Piere Rajotte says in _Brewing Belgian Ales_ > that sucre-candi is sucrose. The dark sucre-candi is > caramelized before being crystalized. Nobody seems to have > a US source. I've tried camelizing my own sucrose. It's > not hard to do. Correct; but more specifically it is inverted sucrose. This seems (at least to me) to be important. While I have not tried it myself, I know of at least one person that has used carmalized sucrose in belgians with sucess. I think that carmalized *inverted* sucrose would work even better. If you want to carmalize it yourself you can do so in a sauce pan over the stove. Remember to use *low* heat and stir *continually*. >There is stong consensus that too much sucrose adds a characterist cidery >taste. I agree with this to a point. My experience leads me to beleive that if sucrose (or almost any sugar for that matter) is used judiciously that cidery flavors can be easily avoided. I think the key is to avoid sugars in all low gravity beers (say < 1.040) and in moderate (say 1.040 - 1.60) gravity beers not to exceed 20% extract from sugars. I think that extract brewers should be carefull here to really consider that quality of the extract that they are using. Some of the cheaper extracts may contain a significant quantity of non-malt sugars to start with. In higher gravity brews (say > 1.060) I think that the amount of sugar that can be used is only limited to what the yeast can ferment. What I mean by this is that you could use an infinite amount of sugar, but after a point even the most ethnol-tolerant strain will quit fermenting and leave the remaining sugar as is. >On the other had high >gravity Belgian ales call for sugar as an adjunct. The purpose is to >lighten the body and maltiness of these high gravity beers. This is >one thing that makes them distinct from say Barley Wine. I think everyone would agree with this. An all-malt tripple having the body of a dopple bock just wouldn't cut the mustard, so to speak. >Rajotte says >Belgian brewers may add either glucose or sucrose to their high gravity >beers. Some say the already high maltose content hides the cidery flavor. I read this in a slightly different light. What I got out of it is that with a significantly high proportion of malt to sugar, the yeast would not produce those cidery flavors. What's your opinion? _ Christopher K.

Date: Tue, 20 Jul 1993 14:51:25 -0400 (EDT) From: Kinney Baughman <BAUGHMANKR at conrad.appstate.edu> Subject: The Tumbleweed Report (Part 2) On to the brewing equipment decisions we've made. The Brewhouse: The brewhouse is literally a house. A 12' x 12' bedroom was plumbed and gas lines run in to give us our brewing room. The boiler sits on top of 4 or 5 courses of concrete blocks encased by 2 x 4's. It's located right by a window. A window fan vents the place. It gets a little hot in the summer. But we're working on cooling the place down now by adding more fans to the other windows. In the winter it's fine. The old living room (14 x 24') is our "fermentation chamber" and office. Nothing fancy. In one corner of the room we have an 8' x 8' walk in cooler. Four insulated walls were built in one corner of the room along with a raised floor on 2 x 4 "floor joists". Plywood floor and walls. A compressor cools the room. Cost was around $2000. The restaurant uses the cooler some but mostly we have it filled with kegs going through final conditioning before being taken to the restaurant. We store our malt and hops in there as well. In the winter we used a thermostatically controlled heater to keep the fermentation room around 65 degrees. This past winter we had temperature fluctuations of plus or minus 5 degrees. This isn't ideal, I know. But it works. We've made some modifications to things this summer, so I think we can do better next winter and hold temps within 5 degrees. That's good enough by anyone's standards. During the summer, we use a common, garden variety window air conditioner. We just put a 11,000 btu air conditioner in a couple of weeks ago and with temperatures above 90 degrees, the fermentation room has been staying right at 65 degrees. Again, pretty good. Fermenters: When Burton and I arrived in November, Tumbleweed was fermenting in 6 1/2 gallon carboys. Some of you know that I designed the BrewCap. Since Burton was a BrewCap fan, too, the first thing we did was attach BrewCaps to each of the carboys Tumbleweed had and turned them all upside down. At one point, we had 50 carboys turned upside down in a two-tiered rack merrily fermenting away! For me it was one of the most beautiful sights I'd ever seen! But after a month, we realized the care and feeding of 50 glass fermenters was too labor intensive even using BrewCaps. While the BrewCap works great for the average home-brewing operation, things were getting out of hand at the brewery. Moreover, in December darned if Bart didn't trade for a 42 gallon stainless steel pot that had been salvaged from a cheese factory about 40 miles away. So Burton and I found ourselves dealing with 40 gallon batches after just one week of brewing at 30 gallons. It had become clear that we had to move away from carboys. And I want to place the blame squarely on the shoulders of one this forum's esteemed members for being the prime cause for us having to move up in size. We were using Larry Barello's idea for a wort aerator and it was foaming the beer up so badly (nicely?) that we could only fill a carboy half-full before moving on to the next one and by the time we had come back to the first one, the foam usually hadn't settled down so we had to shake and stir and do whatever to collapse the foam head so we could get the blasted carboys full!! Thanks, Larry! :-) Filling carboys had become a nightmare. But what to do? Glass is one of the best materials in which to ferment and carboys weren't working out. Stainless steel would have been great but we couldn't find them much less afford them. Bart, on the recommendation of someone in the brewing industry had purchased three 31 gallon black HD polyethelene drums back in October but we were reluctant to use them, being well aware of the complaints about fermenting in plastic. At the same time, I also know of some world-class brewers who ferment in plastic. Darryl Richman comes immediately to mind. I had always figured that most of the problems people have with plastic fermenters stem more from not cleaning and sterilizing them IMMEDIATELY after using them than anything having to do with the plastic itself. So with Bart hounding us to give the drums a try, we took the plunge. I'm happy to say that, on the whole, they've worked very well for us and I would heartily recommend them to anyone wanting to brew on this scale. We use open-head fermenters. That is to say, the entire lid comes off the top so you can get down inside them and scrub off the resins and junk that forms during primary fermentation. These jewels cost about $50 each delivered. Can't beat the price. Once used, they never see the light of day again. Immediately after using them, we fill to the brim with clorox and water and let 'em pickle until the next time we use them. We've had no infections and I don't anticipate any -- at least from the fermenters. We are currently using 18 fermenters. We always need one free for transfers so we can have 527 gallons of beer fermenting at once. Total investment in fermenters is roughly $900. Cam makes up homemade dollys to put them on and we wheel the drums around the brewhouse from that point on. The dollys cost about $35 each to make. Total investment: around $600. (To be continued...)

Date: Tue, 20 Jul 1993 14:52:47 -0400 (EDT) From: Kinney Baughman <BAUGHMANKR at conrad.appstate.edu> Subject: The Tumbleweed Report (Part 3) Brew Kettle: As mentioned earlier, we found a 42 gallon stainless steel pot that had been salvaged from a cheese factory. We had had enough experience with the 30 gallon fermenter to know that we had to get away from siphoning through our wort chiller. So we had a 1" pipe welded about 4" up from the bottom of the pot to allow for the settling of the hops and trub left over from the boil. We have a copper pot scrubber tied around the end of the pipe that sticks into the kettle. This keeps the hops from clogging the pipe and stopping the draining of the wort. On the other end of the 1" pipe we have a reducing "T" fitting (reduces down to 1/2") that splits the draining wort into two directions. First stop is our hop back. Hop Back: If any of you read my article in the Special Gadgets issue of Zymurgy you know I'm a big fan of the hopback so it was high on our list of improvements to make to the brewing operation. We even used the mason jar hop back for a couple of batches when we were brewing 30 gallons at a time. The hassles of changing the hop back every time we switched carboys caused us to rethink things for the 42 gallon pot. We settled on using two 1 gallon stainless steel pressure cookers. 1/2" from the top we had 5/8" OD holes drilled, into which we placed a 1/2" ID bulkhead union to receive the 1/2" copper tubing carrying the wort from the reducing "T". 1/2" from the bottom of the hop back, we had another 5/8" hole drilled and fitted with its 1/2" bulkhead union. The wort flows from it to our counterflow wort chillers. We tie our hops up in paint strainer bags, the kind made from mosquito netting, and tie the bag around the inlet pipe at the top of the pressure cooker. The vent on the lid of the pressure cooker was welded shut so when the lid is closed we have an airtight fit. Works great. And the bag of hops gives yet another filter for the trub that makes it past the chore boy in the kettle. Wort Chiller: We use 30' of 1/2" copper tubing inside of a 5/8" garden hose as a wort chiller. In the winter, we can flow full force through the chiller into the fermenters. In the summer, we have to prechill our cooling water to get a decent flow into the fermenters. On the wort outlet side of the chillers, we have a gated valve to restrict the flow of wort. We back this up or down until we achieve our desired pitching temperature. We shoot for 70 degrees. Kegs: We keg in cornelius kegs. We've scrounged them from several sources. We have right at 80 kegs now. About half of them we bought for around $25. The other half cost us an average of $15 each. All were rebuilt. We spent about $130 rebuilding the kegs. We can do it for less now. We have approximately $1600 in kegs + the $130 for rebuilding. Dispensers: We dispense in two dual tower keg dispensing units, the kind that holds one standard 15 1/2 gallon commercial keg. So we have four beers on tap at all times. Again, Bart the scrounge found these used and I assume we got 'em for a song. I'm not sure of the price. But I doubt he paid more than a hundred or so dollars for each one. (To be continued...) I'm off to Seattle Thursday and then to Portland for the AHA conference. I'll continue these musings when I get back. Hope to see some of you renegades at the conference!

[stuff deleted] Had the pleasure of drinking a lot of Jever at our regular pub while I lived in Germany. I believe the correct phrase that people are refering to is "Friesisch Herb", which means bitter (or dry, astringent, etc) in the Frisian style. The Frisian islands are a chain that run along the North sea coast from the Netherlands along the German coast, perhaps as far as the Danish border (little shaky on my Geography there). Jever is very close to the coast, just across the water from these islands. - ----------------------------------------------------------------------- Richard Akerboom Domain: boomer at sylsoft.com or akerboom at dartmouth.edu Sylvan Software uucp: dartvax!sylsoft!boomer Mechanic St. Phone: 802-649-2231 P.

Date: Tue, 20 Jul 1993 12:27:56 -0700 (PDT) From: gummitch at techbook.com (Jeff Frane) Subject: Noble Aroma Hops Last December I wrote to Al Haunold, who is the acknowledged expert on hops in the US (he's in charge of Hop Breeding and Genetics for the USDA in Corvallis, Oregon, and developed, among other things, Liberty and Mt Hood hops). I wanted to understand what "noble aroma hop" meant and got a very authoritative answer. I just received your letter regarding the term "noble aroma" hop and I will try to answer it. The Germans and the Czechs (remember, Saaz--now called Zatec was a German town in what is now Czechoslovakia--soon to be only the Czech republic)--anyhow they instilled in the older brewing generation (turn of the century and earlier) the idea of a "hochfeines Aroma, Edel-Aroma" if you know German you would know what it means-- it is very hard to translate into English but would be something like "super-fine aroma, Noble Aroma, etc" On and off these terms are found in the literature, but there is always a clear distinction between continental hops (German, Czech, perhaps also Polish) but never are English hops included in this category, nor are the Yugoslavian (Slovenian) hops included in this group. The EBC (European Brewery Convention) and the IHGC (International Hop Growers Congress) have repeatedly used such terms to differentiate from kettle-aroma hops (also called kettle hops) and the high alpha hops (now often referred to as super-aroma hops). I have simply used the term (admittedly not always consistently) in some of my publications to refer to the similarity of our newer continental (European-type) aroma hops with the older aroma hops which the Germans called Deutscher Edelhopfen--and which they often stated can only be grown in certain areas of the world, whre the climate, the soil and the know-how of the grower produce such superb results. A lot of it is humbug, but there are certain traits which these noble aroma hops share: balanced alpha and beta, relatively low alpha and beta (5 to 3, sometimes as low as 2), relatively poor storage stability (typically lose 50% of the original alpha through transformation), low cohumulone content, low myrcene in the oil (below 50% of the oil), high humulene in the oil, ratio of humulene/caryophyllene above 3, preferably above 3.25. Thus we come back to Hallertauer mittelfrueher, Tettnanger, Saazer, Lubelski (Polish) that is it. (Hersbrucker is not in that illustrious group although they have tried to include it after Hallertauer mittelfrueh had to be thrown out because of Verticillium problems -- they also tried to include Perle -- not many brewers agree!) There are now two new German hops, Hallertauer Select and Hallertauer Tradition which are supposedly noble aroma hops. Goldings and Fuggle are not included, although Fuggle and perhaps Goldings (a large diverse group) come close. We think Mt Hood and Liberty come close also. I always hate to ruin a perfectly good opinion with data, but certainly Dr. Haunold comes as close to the Word of God as we can get, I think. - --Jeff Return to table of contents

Date: Tue, 20 Jul 93 16:39:44 -0700 From: arne thormodsen <arnet at kaibutsu.cup.hp.com> Subject: Another data point in the hot break debate After reading this forum recently, I decided to let my latest all-grain stout hot break *before* adding the hops. After half an hour of rolling boil there wasn't a sign of a hot break, so I added the hops. Bang! I got a hot break within 5 minutes. I guess this may be showing that hops do promote the coagulation of proteins. Since I've never done this before maybe I didn't wait long enough. I've always added the hops at the very beginning of boil, and seen the hot break start within 20 minutes or so. How can I get the hot break to occur *without* adding the hops? I'm on an electric stove, so the boil can't be made *really* turbulent (it's a big burner, but not that big). What other options are there? - --arne Return to table of contents
Date: Tue, 20 Jul 1993 16:48:38 -0700 From: Bob Devine <devine at postgres.Berkeley.EDU> Subject: sharing articles? Nearly every club has a newsletter. However one of the persistant problems is coming up with a source of articles. Is there any interest in having a shared collection of articles? For example, if someone writes about experiences with a new yeast, that information is likely to be of interest to several newsletters. Through the wonders of the internet (and other billboards), the sharing would be very easy. I giving this as an "idea" posting, not a "I have the time" posting. Spencer Thomas informed me of the newsletter archive at Cornell but it is not used for sharing articles. So, I suggest that when someone writes an article, it be placed in a convenient spot (perhaps at sierra.stanford.edu). Bob Devine Return to table of contents

Date: Wed, 21 Jul 93 09:07:26 EDT From: sims at pdesds1.scra.org (Jim Sims) Subject: uh-oh! I know my beer has an infection. The question is: What to do about the beer and the (plastic) fermenter? I was experimenting with adding fruit to beers by racking ~ a gallon of beer from the primary or secondary to a gallon jug with fruit. One of the jugs had about 2 lbs of cherries, and apparently (verified by experiemntal evidence :-) not enough airspace. The airlock clogged, the pressure built up, and we had to clean cherry beer off the walls. Most of the beer and cherries were still in there, so i figured i'd keep going and see what happened. I racked it to an empty plastic fermenter (I know, should keep those things filled at all times with fermenting beer :-). Went off on vacation, came back, and decided to bottle the stuff last nite. The strawberry and raspberry versions seemed fine, but the cherry beer had a coupla small 'colonies' of white-ish, grayish, blue-ish thingies floating on the top of the cherries. The wort had an acid taste. Have I just re-invented the ~pLambic beer infection? (how can tell if) Is the beer safe to drink? Will i ever get the 'bugs' out of that plastic ferementer? I left it soaking overnite (so far - still going) in a very strong bleach solution, filled to overflowing. jim Return to table of contents

I tasted 2 totally AWESOME beers at a brewpub in the Twin Cities called _Sherlock's Home_, a Scottish Heavy and a Traditional Porter. The beers were dark in color (pub listed the OG's at 1.046 and 1.042) but extremely light, creamy and smooth in texture. Does anyone know what the secret is to this texture?? Could it be some kind of mollasses or maybe a special carbonation trick. I have tasted beers on tap and in the bottle from all over (including Scottish Heavy's right from the source in Edinburgh) and have never had anything like this. I'd like to try and emulate it with my homebrews.

Actually I went in for the Wicked Ale and came out with their Golden Lager. It tasted fine with much more body than most American lagers. Now I have a question about this Brewery. I've heard in the past that some larger breweries were jumping on the micro bandwagon by selling beers that looked the part. I was wondering if someone from St. Paul was familiar with Pete's. I realize that the term "micro" is somewhat undefined (I've heard under 15,000 bbl/year), but I'm wondering what the thoughts are on this. Next topic: is there an e-mail address to submit additions to the publist? Thanks, John Hale (John.L.Hale at Sprint.Sprint.Com) Return to table of contents

Hall) Subject: Heat Output of Stoves Jack Schmidling says: > I don't have a clue as to how to determine tthe BTU's of my heat source but > it is a NG/forced air furnace I designed for melting aluminum for MM > castings. It will melt 4 lbs of aluminum in 20 minutes. Wow, that's a hell of a way to measure the heat output! Actually, you *can* get an estimate of the heat output from this. Although I realize that Jack was just using rough numbers and that you can only tell how much heat was *absorbed* by the aluminum, not how much was put out by the flame, I am going to forge ahead and figure out what this means in terms of BTUs/hr. Say that you start out with 1.82 kg (4 lbs.) of Al at 300 K (80 F). First, raise it to the melting point of Al, 931 K (1217 F): Heat = (931 K - 300 K) * 1.82 kg * 215 cal/kg/K = 247,164 cal Then, melt it: Heat = 1.82 kg * 94500 cal/kg = 171,990 cal Then, figure out the rate: Heat output = (247,164 cal + 171,990 cal) / 20 min. = 20,957 cal/min = 4,982 BTU/hr Let's compare this with a stove that will heat 5 gallons of water from 20 C to 100 C in 20 minutes: Weight = 5 gal * 8lbs/gal * 1000g/2.2lb = 18,181 g Heat output = 18,181 g * 80 cal/g / 20 min = 72,727 cal/min = 17,305 BTU/hr These last numbers were for a stove quoted at 35,000 BTU (probably per hour), which gives a heat efficiency factor of about 50%. Then again, this calculation gets the water right to the boiling point, and any additional heat will go into the production of steam, so the efficiency could be higher. Bottom line: 1. You probably lose up to half your heat in a regular brewing setup. 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 :-) Reference numbers: Specific heat of Al at 25 C: 0.215 cal/g/K Heat of Fusion of Al: 94.5 cal/g Mike Hall Thermohydraulic Nut Los Alamos Atom Mashers Return to table of contents

I moved the beer to the secondary and added the hops on Sunday, planning to go on vacation Tuesday. As it turns out, I'm now not going on vacation until Friday which means if I leave the hops in the secondary, I'd be dry hopping for two solid weeks (last Sunday to next Sunday). 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. tjb Return to table of contents

I bought a wort chiller and used hop pellets for the first time. After cooling my last batch of hot wort, I tried to syphon the cool wort. I ended up clogging the syphon with trub and pellet rements. Does anybody have a good way to syphon off the good stuff and leave the trub behind? Thanks, Kevin Martin kmartin at magnus.acs.ohio-state.edu Return to table of contents
Date: Wed, 21 Jul 93 14:49:32 EDT From: billok at aol.com Subject: How do I read HB files via FTP? This is not a question about Home brew but about HOMEBREW Digest. I am new to the HOMEBREW Digest and the internet. I would like to download some back issue's of HB Digest, but I'm having a problem. I know that back issues can be found via ftp at sierra.stanford.edu and I can transfer them to my PC (A Gateway 486 running DOS 5.0 and Windows 3.1). But these files are not readable. They have names like "HB1173.Z". I think the they may be compressed somehow but I am not familiar with UNIX and I don't know how to read these files. I would appreciate any help with this, so next time I can ask a question about beer brewing! Thanks, Bill Okula Rocky Point, NY BillOk at delphi.com BillOk at aol.com Return to table of contents

In those days it was the only place that this was true, and may still be so. > What are the best breweries and brewpubs in Portland? > > Well, there's a subject for debate! Try the Pilsner Room, where John Harris brews Full Sail beers and his own incredible pilsner. Try B Moloch, which is connected to the downtown Widmer brewery, has a wide range of local micros on draught, and excellent food. Try the brewpub at BridgePort, where several of their beers are available as cask-conditioned ales, and the pizza is excellent. You can walk from there to the Portland Brewery, where their beer is quite good (eschew the Timberline Ale) -- I generally don't drink it anywhere else. There is also the McMenamin Empire of brewpubs, which are scattered all over the Portland area and throughout the state. Several of them feature movies in conjunction with the beer. It is occasionally possible to get a potable beer at one of this places, depending on who the local brewer is. A lot of people love their beer; I personally avoid it whenever possible. I'm out of touch; there are other brewpubs that have started up which I've never visited. One called Star, I believe, and others which I haven't even heard of. There is a brewery producing "lagers", the Liberty Brewery, but frankly the beers I've tasted were terrifically boring. There are also two connected breweries in Newport and Ashland, bottling and kegging their beers as Rogue. These are terrific, IMO, and brewer John Maier, once AHA Homebrewer of the Year, is one of the most creative and consistent brewers in the Northwest. Teri Fahrendorf makes excellent beers down in Eugene, which are, I believe, only available at the brewpub. Another former homebrewer is brewing good stuff down in Cave Junction. ?? where? etc etc etc Oregon *IS* beer heaven. Sorry, Chris. - --Jeff Return to table of contents
Date: Wed, 21 Jul 93 16:06:38 EDT 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. The first time I filled the tank, I took it to a fire ext. company. When they filled the tank it took about 5 min and they used a loud machine which sounded like a pump. They also weighed the cylinder before and shut off the pump when the tank was 10 lbs heavier. Questions: What is the proper way to fill a CO2 tank? Did the bar's method work? Is the gas from a fire company safe to consume? Thanks Hyrum Laney jdsgeoac at typhoon.saic.com Return to table of contents

I am familiar with papain as a meat tenderizer, and I know it "digests" proteins, but I was wondering exactly how it works in beermaking. Any information would be appreciated.
