---------------------------------------------------------------------- Date: Mon, 24 Feb 1992 07:52:16 -0600 From: rickel at cs.utexas.edu (Jeff Rickel) Subject: Beer gone lemon I have had several commercial beers that somehow went bad and developed a lemon flavor, as if someone dumped some lemonade in them. On a similar but perhaps unrelated note, a few of my beers have had a very subtle hint of a citrus flavor. What is the origin of these flavors? If it makes a difference, I make partial mash ales with dried yeast. Jeff Return to table of contents
Date: Monday, 24 Feb 1992 09:55:30 EST From: m14051 at mwvm.mitre.org (John DeCarlo) Subject: Brewing with Chocolate I want to brew with chocolate. I know this topic is not new, but it came back to my mind after reading the proceedings of the AHA Conference (Volume 11). Fred Eckhardt mentioned using dark cooking chocolate when brewing in the report on his beer and chocolate tasting. Does anyone have any more info on this? My latest plan is to use the brew pot as part of a double-boiler to properly melt the chocolate before stirring into the wort. As others have noted, chocolate will tend to clump and not melt (if not worse) when just dumped into hot water/wort.

Date: Mon, 24 Feb 92 07:26:55 PST From: spl at dim.UCSD.EDU (Steve Lamont) Subject: Aluminum and Alzheimer's Jack "arf" Schmidling says: > From: <S94WELKE%USUHSB.bitnet at VTVM2.CC.VT.EDU> > Subject: Aluminum and Alzheimer's Disease > > >The brain lesions found in AD do indeed contain Al, but the same levels of > Al are found in normal peoples' brains. > > That sounds like something the "tobacco lady" might say on Crossfire. > > How could the controversy ever have arisen if that were true? Yeh, they couldn't say it if it weren't true. Right. I work at the University of California Medical School Department of Neurosciences with a number of scientists doing basic research on the subject of Alzheimer's disease. In fact, I've recently done 3D reconstructions of nerve cells from biopsy and autopsy specimens, detailing the progression of the disease from onset to eventual death. Nowhere, I repeat, NOWHERE in this study has aluminum played the slightest part. There is a bunch of glop called neuritic plaque that seems to form at the synapses. I don't know what it is composed of, offhand (I'll ask when one of my collegues shows up this morning) but it isn't made of Reynolds Wrap, I know that much. Note: I'm not a biologist, I'm a computer graphics nerd, and the closest I've ever been to a medical degree is the one hanging in my doctor's office. But I have access to people who do have MDs and PhDs in the subject in question and I've asked about the correlation between Al and ALZ on a number of occasions. None of the scientists that I've asked has said that there is anything more than the slightest correlation between the two. If you want to worry about something, worry about the supposedly "safe" ultrasound scans that are in use all over the place. On second thought, screw it. Have a home brew. spl (the p stands for punishing my synapses) Return to table of contents
Date: Mon, 24 Feb 92 09:37:41 -0700 From: 105277 at essdp1.lanl.gov (GEOFF REEVES) Subject: Xingu Beer > From: Eric Mintz <ericm at bach.ftcollinsco.NCR.COM> > Subject: Xingu beer > Date: Wed, 12 Feb 92 18:41:36 MST > > Has anybody tried Xingu beer from Brazil?

I'm obviously a little behind on my reading but I couldn't find anyone else answering this question in a quick scan of contents. This month's "Rocky Mountain Brews" - a newspaper like "The Celebrator" - has an article on Xingu. The story is that a "beer consultant" (who's name I've forgotten) has this great scam where he finds people to pay for his travels all around the world to find beers to import. Back in the days of lighter-is-better mentality he was in Brazil where he found a type of "black beer" that was based on an ancient recipe documented by the first white explorers in the region. When someone asked him for recommendations about importing dark beers to compete with Guiness he remembered Brazil and probably thought "Great another free trip to Rio!" so he went down and found that Lagers had replaced the "black beer" but that it was still "home-brewed" in the Amazon. He went in search and found plenty of people that brewed it the old way. However, the old way was one of these chew-the-grain and-spit-based recipes which was unacceptable for import so he contracted with a brewery that was on the edge of ruin and they brewed the beer according to his all-grain no-spit recipe. It was subsequently imported by his wife's company so he could promise the brewery that they would have a market. If anyone is particularly interested in this guy's name or less hazily remembered facts then I'll look up the article again. By the way this was one of the (if not THE) best article I've ever read in the "Rocky Mountain Brews." Geoff Reeves Atomic City Ales Los Alamos NM Return to table of contents
Date: Mon, 24 Feb 92 10:50:57 EST From: eisen at kopf.HQ.Ileaf.COM (Carl West) Subject: boiling on an electric stovetop **theory_without_experience_alert** For boiling in a large pot, would it be helpful to cover the stovetop around the burner with a couple layers of aluminum foil? It seems to me that this should help keep the heat from the stovetop and direct it toward the pot AND aid cleanup in the event of a boilover. Or could it cause some bad/dangerous heat concentration? **end_alert** Carl When I stop learning, put me to bed with a shovel. Return to table of contents
Date: Mon, 24 Feb 1992 10:51:41 -0600 (CST) From: ISENHOUR at LAMBIC.FNAL.GOV (John L. Isenhour) Subject: Gas Burners ingr!b11!mspe5!guy at uunet.UU.NET asks: (edited) >I've seen references to using an old gas water heater burner to construct a >beer cooker. My question is, how would one go about constructing a cooker out >of this? I know I'd have to cut the thing open to get the burner and change >the gas ports for LP instead of natural gas but what else should I know?d I have pulled the gas burner out of a couple of water heaters, its pretty easy. I then welded up some angle iron (1.5 inch on a side) into a box shape that would allow a 33 qrt cooker to sit inside on the angles (just so happens that given a wee bit of tolerence, a SS keg will rest inside this also). I then welded a piece of flat stock across the center, just underneath the angle that the pot rests on, bent such that the burner was held a the right height from the pot. The burner had a little screw-like item in the bottom center of the burner so I drilled a hole in the flat stock - the screw slides into that for positive positioning). I attached another section of flat stock on one side to brace the bottom of the burner where the gas is injected. (sorry, theres no way to discribe this better on character cell media) There is an (aluminum?) tube that comes off of the burner and attaches to the gas control box which has a flange fitting. I cut that off with a pipe cutter (hacksaw would work). I went to an automobile supply and got 30 feet of rubber like gas line that fit the tube. I attached the rubber tubing to the aluminum tubing with a hose clamp. About 5 or so inches down the rubber tubing from that connection, I put an inline on/off valve (I used a welding O2 needle valve but a variety of items world work). This is for adjusting the flame to perfection and as an emergency shutoff (like for boilovers). The other end of the tube is connected to a "barb" with a hose clamp then a shut-off valve. This connected to the natural gas supply (typically near my gas dryer). *This stays turned off at the supply side when not in use*. I am sorry I cannot send a picture, If you mail me I can send measurments or whatever you need. The bottom of a 33 qrt cooker is about the size of one of the squares that makes up the box. This size in case I wanted to bolt it to something higher (gravity hop back) but I can easily pull the burner off and throw it in the yard and attack it with oven cleaner if I get a boil over. I also typically put an aluminum foil skirt around the thing when I am cooking outside to keep the heat concentrated. I have used the system for over three years now (extensively) with no apparant wear on the hosing. I have enough tubing to brew outside in the summer, and I can run it in the basement or kitchen in the winter. I used natural gas because thats what the burner was made for and thats what I had access to. - John Isenhour Isenhour at lambic.fnal.gov hopduvel!brewmaster at linac.fnal.gov Return to table of contents
Date: Monday, 24 February 1992 11:59am ET From: joshua.grosse at amail.amdahl.com Subject: Trub and blowoff Michael Charlton discussed trub in HBD 830. Miller's TCHOHB recommends trub removal for the very reason he stated. The O2 will be taken from the trub instead of from free O2 in the wort. Of course, I don't have a copy with me at the office else I could quote the reasoning. For five out of the last six years that I've been brewing I've used a blowoff tube, and found the results much improved. That first year, though, I used a plastic fermenter and had lots of sanitation trouble. My switching to a carboy and going with closed fermentations helped the sanitation, which likely help the flavor more than the blowoff tube. The last 6 months or so, I switched from extract based brewing to all-grain, and added a wort chiller. I've noticed tremendous amounts of trub, and now delay pitching for 3 or 4 hours after sparging and racking into a carboy. Then I rack again before pitching. As I culture yeast in a carboy, I typically rack onto my starter. The last batch, I left nearly a gallon of trub behind. Lately I've been using Wyeast 1059 - American (Chico) Ale yeast. This yeast never needs a blowoff tube. I find that the combination of no (or little) trub and no blowoff makes a great tasting beer. In the article he mentioned a brewmaster who recommended staying away from high temperatures due to fusel alchohols. My understanding (Millerazian) is that higher temperatures promote esters and reduce diacetyl. I also learned in my BJCP class that the level of Valine in the malt will affect diacetyl levels perhaps more than the yeast or the temperature. The instructor, Fred Scheer of Frankenmouth Brewery, says that he adjusts mashing and fermentation schedules depending on the results of the malt analyses he gets with each batch. Homebrewers don't get analyses. In general, Scheer believes that maltsters sell overmodified malts to homebrewers because they think, perhaps rightly, that we're more concerned with degree of extract than any other aspect of our malts. The jury may be out as far as blowoff is concerned. However, there appears to be documented evidence (Miller, et.al.) that trub will affect yeast behavior in ways which may be harmful to quality beer. - ----------------------------------------------------------------- Josh Grosse jdg00 at amail.amdahl.com Amdahl Corp. 313-358-4440 Southfield, Michigan Return to table of contents

Date: Mon, 24 Feb 92 9:27:43 PST From: winter at cirrus.com (Keith Winter) Subject: Artificial Carbonation First, let me thank all those that responded to my request for the CO2 chart. I appreciate the fast responsees. Now for another question: the chart doesn't provide all that I was looking for. What I need to know is how long at a particular pressure and temperature does it take to carbonate to the level that is shown in the chart? If I wanted to obtain the level of carbonoation of a British Ale as shown in the chart, how long should it take at the indicated temperature and pressure? I know I should relax and all, but tapping a glass of beer each day to check for the right level of carbonation will undoubtedly empty the keg by the time the right level is reached. So far, I've had the keg at 8 psi and 40 degrees F for a week and the level of carbonation is not nearly enough - only a very few bubbles initially (other than a very nice head) which disappear relatively quickly. Any input would be greatly appreciated. - ------------------------------------------------------------------------------ Keith Winter at Cirrus Logic, Inc.

Date: Mon, 24 Feb 1992 12:21 EST From: STROUD <STROUD%GAIA at leia.polaroid.com> Subject: Trub: a data point Here is one data point in the trub vs no-trub debate. Joel Bauman, a member of the Boston Wort Processors, conducted a trub/no-trub experiment for our club in 1989. Please note that this was a 2-stage, no blow-off fermentation in glass. Also note that this was an excess-trub experiment, since the full trub was fermented with half the volume of wort. The following except is taken from the club newsletter: Fermentation on trub vs racking off before yeast pitching. The beer was an all-grain pale ale. Starting gravity was 1.052 (I didn't get a complete recipe. A liquid ale yeast was used). After the boil, the wort was cooled, then racked into a sanitized container which was stoppered and placed in a refrigerator to achieve a good cold break. After the trub had fully settled out, half of the wort was syphoned into another sanitized container, taking great care to leave all of the trub behind. The same yeast was pitched into both containers and fermentation was allowed to proceed normally. Joel commented that the trub-containing beer fermented out in 5 days while the trub-less beer took a bit longer, 7 days. Comments from a blind-tasting that the club held: Opinion was virtually unanimous: almost everyone favored and could pick out the trub-less beer. It was smoother and seemed better balanced. The beer fermented on the trub had a harsh bitterness to it that stuck on the tongue. ************** This experiment convinced me to start racking my beers off the trub before fermentation. I do two-stage ferments in glass, no blow-off. If you do blow-off, your mileage may vary. Steve Stroud Return to table of contents
Date: Mon, 24 Feb 92 10:29:08 MST From: Eric Mintz <ericm at bach.ftcollinsco.NCR.COM> Subject: My new wort chiller! Hello all you that have considered a wort chiller but thought it would be too much trouble! After the recent banter about the virtues of wort chillers, I decided I had to have one. It was relatively cheap (about $18) and easy (10 minutes to assemble) and it cooled my wort (cool to the touch) in 30 minutes! Here's what I did: at the local hardware store, I bought a 20' coil of copper tubing (ID = 3/8", OD = 1/2") and enough clear plastic hose (ID = 1/2") to reach from the brew kettle (on the stove) to my sink and back again. I already had the fittings to connect the plastic hose to the sink faucet. The coil fit right inside my 15.5" dia brew kettle and the plastic hose fit right onto the sink fitting and the copper tubing. That's all there was to it! Turn on the cold water; cold break in 30 minutes! - --Eric Return to table of contents
Date: Mon, 24 Feb 92 10:38:59 MST From: Eric Mintz <ericm at bach.ftcollinsco.NCR.COM> Subject: A real stout stout! I just put up a real high gravity (1.088 !!) stout: 12.5 lb grain for 2 gal of wort (ok, I wasn't aiming that high but the boiling time got away from me :-). I pitched #1007 Wyeast -- I'm expecting a FG of 1.022 (?). I used 2oz of Cascade .5 alpha. The qustion is this: should I dilute the wort some or should I expect reasonably good results as is? (or maybe a better question would be: am I correct to expect a FG of 1.022 given the above decription?) - --Eric Return to table of contents
Date: Mon, 24 Feb 92 08:21:25 MST From: abirenbo at rigel.hac.com (Aaron Birenboim) Subject: Kolsh, Kegs, and Krausening I've got 3 K's on my mind this morning ;-) 1) I have a friend who likes Kolsh.... and I'd like to try and make him some. I think Kolsh is an Alt... but i expect that it is somehow different. In a competition letter i just got they had Kolsh as a seperate sub-class of Alt.... just like they had Berliner-Weisse as a seperate sub-class of Weizen. Anybody have a recipe or suggestion on how to emulate Kolsh? I've never seen it, so i need some help here. 2) I never thought i'd be saying this, but here i am.... looking at getting a kegging system. Unfortunately, I've always ignored the kegging stuff here in the past. a) What is a good price? Is Alt. Bev.'s $139 package a good deal? Which type of keg is the Kornealius (Cornealius?) (ball or pin). Alt. Bev's system uses 1 guage... Will this be all i need to ARTIFICALLY carbonate? b) I seem to remember an artifical carbonation discussion discussion a while back. Apperently this method is not at all trivial. There was some kind of carbonation chart... Anybody have it? Any references on artificial carbonation? Any reason why true keg conditioning is better than artificial? c) Quick disconnects... are Alt bev.'s a good price? Foxx?? Others?? I'd like to keep several kegs around, and move the CO2 supply around between them as needed. d) How well to counter pressure bottle fillers work? Is $30 for one fair? It seems to me like the best thing would be to rack into keg, artificially carbonate, then just use counter pressure filler to bottle for portability/competition. Will my flavors be effected by this? BTW... what the heck is a counter-pressure filler? How does it work? What does it look like? There will be an equipment auction tomorrow (tues) benefitting the boulder brewing club (name unknown)... i might try to pick some things up there... thanks for any advise! aaron Return to table of contents
Date: Monday, 24 Feb 1992 13:51:03 EST From: m14051 at mwvm.mitre.org (John DeCarlo) Subject: New Brewers Why do people brew their own beer? We all have our answers to this, but I thought I would tell a little story related to this question and to the issue of teaching others how to brew. I have got one friend started in brewing awhile ago, and another just got a kit for Christmas. Both are fairly sophisticated beer drinkers and neither had really tasted much fresh brew except my own and that at brew pubs. OK, they can taste that my brews aren't professional quality :-) Anyway, I think that both were somewhat intimidated, one tasting some obvious and not-so-obvious defects in his beer already. So, I got them to join the local brew club and go to meetings. After helping judge the latest contest, at which there were quite a few obviously and badly contaminated brews, they felt much better. I figure this is the "I have made/may make in the future mistakes in brewing, but they can't be *this* bad" (or at least if they are, it gets dumped). Trying to figure out the source of a bitter, slightly metallic off taste is a very different thing from a beer that smells bad and tastes sour, or one that is so oxidized it shrivels your tongue. Anyway, paradoxically enough, both my friends are much more enthused about their own beer brewing after seeing such horrible examples of the art. It is making me completely rethink my philosophy of getting others to brew.

Date: Mon, 24 Feb 92 11:39:04 -0700 From: DAMON_NOEL/HP0800_01%hpcsee.col.hp.com at col.hp.com Subject: boiling I gave up stove top boiling after the wife became unbearable about burnt paint and discolored stainless. The biggest need was for lots of hot water and often quickly. My answer was brute amps. A 7 gallon plastic pail with two 4500 watt hot water heater elements (available cheaply from a discount plumbing supply) inserted through the bottom, an adjustable thermostat also bolted to the bottom (underneath), an aluminum ring about 4" tall bolted to the bottom lip of the pail, a heavy 220 switch and a cord to plug the whole thing into the dryer outlet. This rig will bring 6 gallons of cold water to a boil in 4-5 minutes. I was surprised to find that the heater elements don't burn the plastic. The water keeps them from getting too hot. The only caution is that if the elements get out of the water they will quickly burn up. I got tired of trying to pour boiling water out of this rig into a mash tun or whatever, so my next task is to convert a 1/2 keg into a similar outfit, but with a 3/4 gate valve on a tap into the bottom. I keep the thermostat set for 170 water which makes for a ready supply of sparge water. I think converting an old hot water heater would be more trouble than it's worth. Invert sugar is available from candy making suppliers. They also sell a product for converting your own, I think they said it was some form of acetic acid? There was a reference to an Aladin thermostat a while back...I tried to get one at a local hardware store and what they showed me was what appeared to be a thermostat controller for a furnace. It wouldn't work without a thermocouple, presumed to be in the furnace. I'd like to find a rig to put on my reefer to be able to get the thing warm enough for controlled fermentation. Could somebody fill me in on what the unit was like that was mentioned in here a while back and how it was adapted to the reefer? Return to table of contents
Date: Mon, 24 Feb 92 13:44:21 CST From: Jacob Galley <gal2 at midway.uchicago.edu> Subject: My first lager needs advice I have a few questions about what to do with my first lager, but first, I'll tell you the long history of what is turning out to be a very pleasant beer. I based the recipe on Charlie Papazian's Rocky Raccoon: SURPRISED FROG LAGER 3.3 lb Munton & Fison extra light extract ~.4 lb Briess amber extract ~.5 lb Crystal (40 ^L, if anyone cares) 12 oz Clover honey .5 cup Corn sugar (I couldn't help myself. I wanted a strong beer!) 1 oz Cascade hop pellets, 4.9% AA (60 minute boil) 3 oz Fresh grated ginger root (15 minute boil) "the obligatory 1/3 licorice stick" Pilsen lager Wyeast I measured the OG at 1026, although in hindsight I think the brew was still a little warm. . . . Let's call it 1035 or so. I put this in my fridge (42 ^F) on 9 December, in hopes that it would be finished by the time I got back from Xmas break. It certainly wasn't! On 16 January I measured the specific gravity at 1021, and it was still pretty sweet. On 8 February, though I knew that it was not done fermenting, I bottled with .5 cup corn sugar and put all the bottles back in my fridge. A day later, I decided to move two bottles into my pantry, to see if anything interesting would happen. Well, two weeks later (last night) I compared a re-refridgerated finished-at-room-temperature bottle to one of the normal cold ones. The cold one had NO head, was still plenty sweet, mild carbonation, very distinct ginger character, and had a "final" specific gravity of 1013. The warm one had a killer head that headed down the side of the bottle and stuck to the glass. It was not at all sweet; the ginger apparently contributed a significant amount of bitterness, and was no longer very recognizable. It comes off as a rather hoppy pilsner "with a twist." This is my best beer yet. But now I'm wondering, how much am I going to ruin the flavor if I move the rest of the bottles into my pantry to finish at room temperature? How long is it going to take the beer to finish in my fridge? My only two reasonable options are fridge (42 ^F) and pantry (68 ^F). I'm also wondering why this recipe took so long to ferment. My roommate was not too pleased at the space in the fridge the carboy hogged for an extra month. Is 42 degrees on the low end for lagers? How much does that variable affect flavor and fermenting time? (And while we're at it, how much does fermenting time affect flavor?) I'm not really this patient, just this cautious. I'm also wondering about brewers licorice as opposed to other heading agents or none at all. In my experience, "the obligatory 1/3 licorice stick" makes a good head in, say, a three-week-old beer, but open a bottle of the same batch at three-months-old, and you need to get a sponge. Okay, I've probably taken up too much space now with these questions, but I bet there are several people out there who could learn some from our expert panel on these issues. I'd just like to say again that I highly recommend the above recipe, and Rocky Raccoon as a base for experimenting with specialty lagers. Cheers, Jake.

I don't know much about beer pumping, but with sanitation always an issue, i thought you should know about peristaltic pumps. They run in the $400 range and function by having rollers pushing on a u-shaped piece of hose. The rollers squash the hose against an outer housing and move along the length of the hose-sort of a progressive cavity pump. Anyway the beer or whatever you are pumping only touches the hose, so it is easy to clean or you can simply replace the hose. Good luck with your search-hope this helped some.

Reading also has many factory outlets, so if your married like me these trips can end up costing $. I do not know how much general admission will be or how to purchase in advance. One problem for some folks is that the AHA conference is being held the same time. ***************************************************************** Dear Fellow Microbrewer, We would like to introduce you to the Great Eastern U.S. Invitational Microbrewery Beer Festival, and to invite you and your fine microbrewery to participate in this existing first-time event. The Festival will be held Saturday, June 13, 1992, in the Stoudt's Brewery Hall in Adamstown, Pa. from 1 to 5 p.m. Our large, appealing pavilion will be the setting for up to 50 "Tasting Tables" where guest will be offered samples of microbrewed beers. We will provide ice or a tapping system according to your preference, and each brewery will be identified by an attractive sign to be furnished by the festival promoters. This tastefully planned event will include a luncheon provided for guest as part of their admission fee. Participating microbreweries will receive complimentary passes and have the opportunity to preview the event before general admittance. We want to emphasize that this expo-type event in NOT a competition. It is an opportunity for you to share your prized microbrewed beers with a large, specially targeted audience -- customers who appreciate the type of beer created only by microbreweries. In addition to cultivating a demand for your particular product, you will be helping to generate interest in our industry's craft. The festival promoters will arrange extensive media coverage including television and radio publicity. We will be mailing news releases to more than 100 newspapers, and will send invitations to more than 13,000 beer lovers. All we need from participating microbrewers will be seven cases or one half barrel of each beer offered for tasting, with a limit of three products per brewery. We will be happy to work with you to arrange delivery of your product. The only beers accepted for tasting will be those produced by North American microbreweries (producing less than 15,000 barrels annually) or specialty beers brewed by contract breweries; all beers must follow traditional English brewing standards or the German Purity Laws of 1516. No American-style beers made with corn or rice will be featured. We're looking forward to making this an annual event, one that will be eagerly anticipated by beer connoisseurs and speciality brewers alike! Press fill out the form enclosed and send it to the Great Eastern U.S. Invitational Microbrewery Beer Festival as soon as possible to reserve your space at the Festival. Remember, early commitment will ensure inclusion of your brewery's name in pre-event press releases. Thank you, and we look forward to seeing you in June. Sincerely, Ed Stoudt ************************************************************************ Hope to see you there! Geoff Woods gcw at garage.att.com Return to table of contents

Why is it important to replace the hose with a fermentation lock after the bulk of fermentation? I am assuming that the other end of the hose is sitting in a jar of clean, probably sanitized water. Is this not enough "lock"? I`ve never had any problems with this method yet anyway. - Bryan Return to table of contents

I've got some that are rated 12% (alpha I guess). I like hops and tossed some in (1 oz) into a recent batch A taste during bottling showed quite a hop flavor though different from multi ounce hopped batches I've made. Is galena used in any commercial beers? Joe Uknalis Return to table of contents

Hi all; I've been toying with the possibility of building an immersion heater to heat sparge water and boil wort outside of the kitchen. It started while considering the Bruheat boiler, followed by my buying a 6000watt 240v (9.6 amp) "tank heater" for a few bucks at a surplus shop. My idea is to suspend this heater (a rod-shaped loop) dipping into the wort, (so I don't have to bore into my boiling vessel) but I'm having a problem finding either a switch to regulate the output of this thing so I don't have to turn it on and off by yanking the plug (conveniently located behind the dryer). I first considered an electric stove knob, but after looking at those on my stove, I see that these 240v switches use a +, -, and comm connection instead of the two-leads on my heating element, and I'm unsure now if this will work. Now I'm thinking about electric water heaters... These clearly have switches for similar heating elements, and I might be able to use a thermostatic switch too (that would be ideal). Electric water heaters are pretty rare here, though, and I haven't found the parts, (or better a free leaky heater to scavange them) and I remain uncertain if this will work as planned. Does anyone here have the slightest idea what I'm talking about? The guy at the hardware store thinks its all pretty funny, and the only other advice I can get here is to pay up my fire insurance before I plug it in. Any input on how you guys might have built similar items, or sources for the kind of switches I need would be very much appreciated. thanks, dennis Return to table of contents
Date: Mon, 24 Feb 92 18:11 CST From: korz at ihlpl.att.com Subject: Large Fermenters Does anyone know if it is safe to keep beer in HDPE for a year? The Cole-Palmer reactivity chart says HDPE has "no effect after 30 days" or something like that for both beer and chlorine water. I plan to make a 15 gallon batch of pseudo-lambic (including Brettanomyces and Pediococcus cultures) but since the cultures are so expensive and the beer takes so long to mature, I want to make 15 gallons of it. The only reasonably-priced 20 gallon container I can find is a HDPE bucket with big, molded handles from Cole-Palmer (~$25). I've considered using my SS keg, but it's a Heileman's Sankey keg and thus has no handles (just the thought of lifting it up onto the drier gives me a backache). I've also considered making three 5 gallon batches side-by-side, but I anticipate problems splitting the cultures among the three carboys. On second thought, maybe I *should* make three of the same batch, but then pitch the culture starters at different times. It only makes sense that the more sugar I let the Saccaromyces eat, the less there would be for the Brett and Pedio, so I could try to find the proper SG to pitch the "other" cultures for the proper amount of their respective flavors. While I'm at it, I might as well ask about 7 gallon carboys. It appears that my retailer's distributor no longer carries them. Does anyone know where I can buy some? Al. Return to table of contents

Date: Mon, 24 Feb 92 23:55:02 -0800 From: Lee J. Slezak <slezakl at atlantis.CS.ORST.EDU> Subject: Yeast in the Secondary for a Framboise? Hi all: Currently I have a Framboise in the carboy fermenting away nicely. I got the recipe out of the cats-meow, anyway it (the recipe) says to add an additional 10 cups of raspberry puree to the secondary fermentor. My question is, should I pitch some champagne yeast in with the secondary and the new raspberries? What would that do? The only reason that I ask about champagne yeast is because I have heard of people putting it into the secondary on imperial stouts. So, should I pitch any type of yeast into the secondary? The recipe doesn't call for it, but I would think I would want something in the secondary to work on the new raspberries. Anyway what do you people think? You were all so helpful with my question about the Hazel-Nuts in the bottles, so how about this one? Thank you all very much and I will look forward to hearing from you. Happy Brewing- Lee J.
