You can't buy the stuff but you can make it. 800g glucose powder 200g dextrin powder (NOT dextrose!) Mix the powders well. Make an 80% solution in water eg, take 800g of the mixed powder and add to water. Heat gently to dissolve. Make up to 1 litre with water. Boil to sanitise and store in the fridge. This doesn't have the consistency of syrup - the viscosity is quite low, but it works well as a very close substitute for commerical maltose syrup.

One 40' coil in a bucket filled with ice water connected to another 40' coil that goes in the kettle. It chills 11 gallons of boiling wort to 70F in 15 minutes. In the winter it takes one 18 pound bag of ice and I have ice left over, in the summer it takes two bags. Rick Pauly Nuc Med Tech Charlotttesville,VA Return to table of contents

I found his statement that most Bitter inclines towards the hop bitterness rather than bitterness in balance with maltiness quite interesting. As a long time drinker of bitter (!) I would say I am frustrated at the lack of bitterness in most commercial Bitter. Of course personal perception has a lot to do with this. It is also regional: being born and raised in the West of England I know that beer in this area inclines to the malty, not to say sweet, which is a pity because I like them bitter. Beers from the North East of England seem to be much more satisfactory in terms of bitterness. Nether area is is very close to hop producing areas, although Herefordshire and Worcestershire are slap bang in the middle of them. Some beers from Kent do seem to feature the hop quite highly, especially Shephard Neame's various brews. Another point is that hoppiness (hop flavour) is important and beers that are not particularly bitter can be well balanced if they have good hop flavour. I'm starting to feel quite thirsty now :-). What I what to know is how did your travel the length of the country, drink 200 pints(?) of beer and arrive safe and intact. A most impressive feat. MICHAEL NEWMAN Return to table of contents
From: "Braam Greyling" <acg at knersus.nanoteq.co.za> Date: Tue, 2 Jul 1996 14:09:09 +200 Subject: KEG CONVERSION, help needed Hi, I have bought three 50 litre = 13.2086 gallon (U.S) stainless steel kegs. I am in the process of converting these into a nice brewery. I have a problem with the mashtun. My kegs have already a hole on the side.The hole is very near the bottom of the keg. How can I make a false bottom ? I got some aluminium mesh and an aluminium rod. Should I rather get stainless steel ? Does anyone have an easy idea on how I should make a false bottom ? There is a ridge near the bottom of the keg and I thought maybe I should let the false bottom rest on it. Only thing is I suspect it may be too far from the bottom. How far can the false bottom be from the real bottom ? Also, after working with the kegs I notice some greyish stuff on my hands, almost like grey dust. What can it be, will it harm my beer ? Should I scrub the kegs with soap and water ? Thank you Any help will be appreciated.

From: "Dave Higdon" <DAVEH at qesrv1.bwi.wec.com> Date: Tue, 2 Jul 1996 08:54:06 EST Subject: Re: hops in spaaace So how about it, oh great and wise collective? If I were reading (or even writing) a story in which the hero/heroine were a brewster, what quirks should I expect from zero gravity brewing? What types of yeast would flocculate best, or will a filter be mandatory? Will there finally be a market for better dry yeasts? Will an ordinary bubbler airlock still work, assuming the fermenter is in a pressurized cabin? How will I get my OG and FG readings? Will we have to adjust alcohol levels? Just what effect will zero-g have on alcohol tolerances? If you were to brew in zero gravity I would think ale yeast would be best to use since the beer would be floating inside the carboy you would not want lager yeast, bottom fermenting , because it could let out the CO2 under it building up pressure and pushing the beer out the air lock. But who's to say it would fall to the bottom so I guess ale yeast could do the same. Return to table of contents

I don't know what the dreaded problem with t*st is, but the word can, apparently, be included in our messages SOMETIMES. Could anyone clarify this trivial, yet noticeable, dilemma? Good Brewing!!!

From: George_De_Piro at berlex.com (George De Piro) Date: Tue, 2 Jul 1996 09:31:29 -0700 Subject: Priming within the Reinheitsgebot At first I was just going to reply to this post (originally in HBD 2088) via private Email, but then realized there may be other relative beginners who would like to know this. German brewers have several ways they can carbonate their beer and be in accordance with the Reinheitsgebot (Beer purity law). Their first option is to force carbonate, much like those of us with kegs do. The difference is that they must use CO2 collected during fermentation, not from an industrial source. They can (and often do, especially with bottle conditioned beers like Weizen) Krausen the beer. That is simply adding some fresh wort and yeast at the high krausen stage to the flat, but fermented beer. This is tricky to duplicate at home because you have to know in advance how fermentable your wort is to calculate how carbonated your beer will be. They can also add Speise (unfermented wort, literally, "food") to the fully fermented beer. This is like Krausening, but without adding fresh yeast. I often use this method. Just save some of your wort by canning it on brewing day. You'll see how fermentable it was by the SG readings of the ferment, then you can calculate how much to add at bottling. The easiest thing you can do at home is to add dry malt extract at bottling time (3/4-1 cup, I think. Check the books, I never do this). Even easier is priming with glucose (corn sugar). This is not allowed if you are claiming to be brewing by the Reinheitsgebot, though. George De Piro (Nyack, NY) Return to table of contents
From: Rob Emenecker <robe at cadmus.com> Date: Tue, 2 Jul 96 09:38:21 PDT Subject: oxygenation, stuck fermentation, stupid brewer tricks Hello all! I'm jumping in from the "lurking pond" to get an answer to the age old question.... "Is My Beer Ruined"! I brewed an English Brown Ale this past Sunday using a single infusion of 156*F for 90 minutes then a mash-out at 170*F for 10 minutes. The sparge took about 1 hour and proceeded without incident. Boiled for 75 minutes adding hops at 15, 60, and 75 minute intervals. Chilled with a counterflow chiller. Aerated for 15 minutes with an aquarium pump then pitched 2 packets of M&F rehydrated yeast. Yeast was pitched at 7:00 PM on Sunday and the brew's O.G. was 1.049 (70% extraction efficiency). Monday morning the brew was happily bubbling away. Monday afternoon there was no activity whatsoever. Cripes! What could have gone wrong? Is My Beer Ruined? In a fit of despair I paddling/splashing the hell out of the brew for about 20 minutes (assuming that it was not properly aerated). After 1-1/2 hours I began to see bubbling again; about one bubble every 1 minute. This lasted all of 4 hours then it died again. Okay so maybe it was an oxygen issue? What next, was the yeast dead (please do not jump in with semantic corrections... denatured, autolyzed, disassembled, dead, all the same to me)? I rehydrated it in boiled water that was cooled to 80*F before adding the yeast. Do I cut my looses and try again or can the brew be salvaged? Before you answer consider this... if you solution is going to cost me money and there is no certainty that it will work, then I would prefer to brew another batch rather than p#ss away more homebrewing funds. Since I mentioned oxygenation, I caught the recent inquiries about the oxygenator and alternative sources of oxygen. Any additional info folks could provide would be appreciated. Purchasing the Oxygenator from Liquid Bread makes it easy to get every a la "one stop shopping", regardless, if I can acquire the parts individually and a lot cheaper I would prefer to do so. On a final note... I wanted to share my latest stupid brewer's trick from the brew session on Sunday. I mash in a 10 gal. SS pot which I keep in an insulated box during temperature rests. Through trial and error I learned that "preheating" the box inhibits any great heat loss at the first temperature rest. This Sunday I put a 4 gallon pot of boiling water into the box. Along with the pot I put my thermometer sitting upright in a bottle adjacent to the pot. Closed the box lid and let it set for 20 minutes. After 20 minutes I opened the box to check the temperature and steam billowed out. Oh, by the way, did I mentioned that the thermometer was a digital one. Doo! Doo! The LCD display melted and fused with the guts of the thermometer due to the intense steam trapped inside the box. Now you know why I am so oversensitized to p#ssing away homebrewing funds ;) **************************************************************************** | (remenecker at cadmus.com) | (RobEmnckr at aol.com) | | Cadmus Journal Services, Inc. | Brewery Manager, Standing Rock Brewery | | Linthicum, Maryland 21090 | Proud Purveyors of "Hairy Dog Homebrew"! | | 410-691-6454 / 684-2788 (fax) | (410) 859-9169 (voice only) | **************************************************************************** Return to table of contents
From: KennyEddy at aol.com Date: Tue, 2 Jul 1996 10:30:00 -0400 Subject: Pressure Cooker Wort Mike in Dallas asked: <<Has anyone ever boiled their wort in a pressure cooker. Granted, it might take a large cooker to boil all of the liquid, but since the liquid retention would be so great it seems like a good idea to try.>> NOT a good idea! (1) It's unnecessary from a sterilization standpoint; your chilling/racking mechanism is still a much larger contamination risk than whether your boiled wort is sterile. (2) Volatile evaporation will be reintroduced into the beer. In particular, DMS (cooked-corn flavor/aroma) will build up and YBWBR (you beer will be ruined). Open boiling is fine. Losing water is fine. Just plan for it in your recipe / technique. Ken Schwartz KennyEddy at aol.com http://users.aol.com/kennyeddy Return to table of contents

From: John Adams <jadams at pipeline.cnd.hp.com> Date: Tue, 2 Jul 1996 08:51:06 -0600 Subject: 1996 Colorado Brewers Festival 1996 Colorado Brewers Festival The Colorado Brewers Festival was held Saturday and Sunday June 29 and 30 in Fort Collins, Colorado. Saturday was a fantastic Colorado summer day, the beers refreshing, and the downtown atmosphere was perfect. Last years festival was (unfortunately) held in a less than ideal parking lot (due to construction downtown) but this year's event returned to Olde Town with 21 beers from 21 breweries. This is the original Colorado-only beer festival and still better than the Lodo fest I attended last weekend (even thought they used last year's mugs). Many of the beers were nothing fantastic (but good never the less), one beer bad enough to find the spooge bucket, but my 'best of show' goes to IL Vicino's Wet Mountain IPA with B.F. Coleman and Palmer Lake breweries as runners up. John Adams - --- Range River Red (4 stars) B.F. Coleman Brewing (Judge Baldwin's) Colorado Springs, Colorado A nice dry hoppy flavor. Flavored with a hint of raspberry and wheat, this has a slight raspberry tartness and very very drinkable -- Nice! Honey Rose Amber Ale (2 stars) The Coophouse Brewery Broomfield, Colorado The Coophouse recently went from extract to all-grain. This is a pleasant spicy ale, with a little diacytle that is noticeable. Clean and drinkable. Duke of Ale (2 stars) Fleetside Pub & Brewery Greeley, Colorado Not a bad beer (maybe it just the big pour)! A roasty taste that has a slightly astringent taste. Slightly hoppy and finishes dry. Wet Mountain India Pale Ale (5 stars) IL Vicino Oven Pizza and Brewery Salida, Colorado YUM! Very hoppy, slightly bitter IPA. Nice centennial hop character that has a dry finish. This beer wins my personal Best of Show. Seamas' Irish Red Ale (3 stars) Namaqua Brewing Company Loveland, Colorado Namaqua had a very good beer at the Lodo fest so I had to check them out. A nice mild-medium bodied ale. Slightly bitter, dry finish and clean. Very pleasant beer. Levity Ale (3 stars) Odell Brewing Fort Collins, Colorado Nice clean, mild taste that is slightly sweet. Not too much or too little, very quenchable. Palmer Lake Cherry Velvet Porter (4 stars) Palmer Lake Brewing Company Plamer Lake, Colorado This beer is velvety and smooth. Slightly tart finish and creamy. I talked with others who later in the day tried this and hated it. Maybe they got the Palmer/Powers kegs switched or the heat of the day took it's toll. Cherry Lager (0.5 stars) Powers Brewing Company Brighton, Colorado This beer was really bad, it gets my 'Dog Award' (which is not given very often). Oxidized and astringent, YUCH --I dumped this beer after two swallows! Pick Axe Pale Ale (3 stars) Tommyknocker Micro-Brewery Idaho Springs, Colorado A slightly bitter beer that has a medium hoppiness. Needs a little more hop flavor, pleasant and drinkable. Slightly astringent. Rattlesnake Kate's Vienna Lager (2 stars) Union Colony Brewery Greeley, Colorado A nice clean lager. Spicy and refreshing but nothing out of the ordinary. Artic Wheat (3 stars) Mountain Sun Pub and Brewery Boulder, Colorado I finished the day with this unique, lemongrass and mint wheat beer. Very nice for a hot summer day beer. Lemony freshness made this a very refreshing beer. Return to table of contents

They sell their brew in VERY large flip top bottles - must be about 1 liter and brown too! They charge about $1.50 deposit when you buy the beer and I just keep the bottle - also, the package store where I get them has been saving them for me and I buy them by the case (like $18).

From: "Palmer.John" <palmer at ssdgwy.mdc.com> Date: 2 Jul 1996 08:49:13 U Subject: Note on Gelatinization With the recent discussion of enzymes and beta amylase in particular, the question arose on how effective a 140F Beta Amylase Rest was in the Starches were not Gelitinized until 149F. Al commented that he thought the 149 came from Noonan's book which in turn may have gotten it from Malting and Brewing Science. I had the same question when I was researching my book* last year and talked with Dr George Fix about it. He stated that 149F can be regarded as the temperature were Gelatinization is complete for all intents and purposes. (Though I am thinking that it may actually be a 90% complete mark, similar to other delineations for other reactions such as Martensitic Transformation in steels.) Anyway, George said that his experiences had borne this out, that gelatinization was occuring at lower temperatures as well and Beta was active between 130 and 155F, 140 approaching peak conditions.

From: George_De_Piro at berlex.com (George De Piro) Date: Tue, 2 Jul 1996 12:21:14 -0700 Subject: RE: Dead yeast in fridge This is in response to the person whose name I can't remember. They said they stored yeast from a previous fermentation in the fridge for two weeks, and when they pitched it no fermentation was evident. Assuming that the first fermentation was healthy, the only things I can think of are: 1. You left sanitizer in a vessel that contacted the yeast. 2. The yeast went dormant and needed to be more slowly roused (I usually add a little fresh wort to them a day or two before pitching). In this case, it should eventually wake up. 3. You shocked the yeast in some way: temperature or specific gravity. Was it previously used for a very high gravity beer, and now your pitching it directly to a 1.035 wort? High gravity ferments usually aren't the healthiest for repitching, anyway. I don't know, but perhaps one of these ideas fits your situation. I usually save the yeast from the fermenter in much the same way as you, and haven't had a problem, even after several months cold storage. Good luck!
