I received several responses from some passionate believers in the concept. Well, to say I was swayed to try it would be an understatement. I tried it yesterday using a good hearty starter and a pale ale recipe and checked on it this morning and it was at high kraeusen and going like crazy. I hope the end product comes out as good as those who wrote and gave me the information. I wanted to thank heartily those that responded to that post. Your information has been used and is now being tested. Have a good day and enjoy a homebrew. Bill Rucker brewzer at peanut.mv.com ruckewg at naesco.com Return to table of contents

I think they attributed the disappearance to the BEERMUDA TRIANGLE. If you see these triangles in your fermentors DON"T stand near them! I read in the Nat. Enquirer that 2 homebrewers in Buffalo vanished after these triangles appeared in their violently fermenting wheat beer! Mike Return to table of contents
Date: Mon, 19 Jun 95 08:02:45 EST From: "RUCKER, WILLIAM G." <ruckewg at naesco.com> Subject: Decoction mashing A question for those who have tried this exercise in self abuse. I tried doing a partial mash recently using a single decoction mash schedule. I took the thickest part of the grist like I have read and raised the temp to 158 deg for 20 minutes and then brought to a boil for 30 minutes. When I added it back to the other part of the mash(don't know the technical name) the temperature increase was not what I expected. I think that I may not have taken enough of the mash to start with but could it also have something to do with how much liquid is taken off as well? I had very little residual liquid when I put the decoction back in. What is the correct quantities/consistency to pull off in the decoction? I eventually got the temp up to 158 deg but I wanted to get it there a little more accurately. Is this one of the big questions or problems with decoction mashing that trial and error is the only answer to? I am preparing to move into all grain with some process tweaks doing partials so this weighs in as a big question for me. I plan on making mostly German style lagers and weizens and I understand this to be the best method. Any info will be appreciated. Private Eamil is fine. If there is enough interest I will post any findings to the digest. Bill Rucker brewzer at peanut.mv.com ruckewg at naesco.com Return to table of contents

Date: Mon, 19 Jun 1995 06:41:02 -0700 From: folsom at ix.netcom.com (Alan Folsom) Subject: Munich Malt and Astringency Awhile back I made a Bock, and used a very large percentage of Munich Malt as per Richman's book on Bock. The beer was good, with some astringency problems. While at Planet Beer I was talking with someone who mentioned an article, by Fix, I believe, which discussed astringency problems using domestic Munich, which probably wouldn't occur with imported Munich. All of this is of course, second hand, and I may be completely off on what was really meant. Does anyone have a reference to that article, or can summarize it for me? Planet Beer was great, by the way, although I was very disappointed in the technical sessions, with little really solid information. I also came away with somewhat more of an uneasy gut feeling about the AHA's ability to represent homebrewing and homebrewers. Good beers, good food, and good people, though, and the offline discussions were quite helpful. Al F. Return to table of contents

Although Using the funnel will aerate(sp?) your wort. This was a topic of discussion in the HBD awhile back. The pros of aerating a second time is that you will give the yeast a kick and your wort will ferment a bit faster and more complete. The cons being that you have a greater chance of infection. 2)There is no problem with leaving the beer in the bucket for the secondary fermentation. If you have a bucket that was designed to be a fermentor (Has lid with a hole for the airlock), this is preferable or you could give "open fermentation a try" although this is not recommended because of the "greatly" increased risk of infection. 3)One can never have too many carbouys. I have 2 carbouys and 1 fermentation bucket. I haven't use the bucket in quit a while though. With the second carbouy, not only will you have a good secondary fermentor, you can do 2 batches at the same time. This comes in handy during the holidays (or other times) when you want to do a stout and a cider for the winter months for example. I hope this helps. David Wright Return to table of contents
Date: Mon, 19 Jun 1995 09:47:52 -0400 From: hbush at pppl.gov (harry) Subject: RE:Looking for a few good dry yeasts Chip Shabazian recommends Nottingham dry yeast. I've had good luck with it , and even better luck with Windsor dry yeast. It ferments fast, doesn't even require a starter to kick off fairly quickly (though I make a starter anyway, I've just trained myself to always make a starter!), and gives a tasty beer. My favorite extract brew thus far has been a English bitter in which I used Windsor Ale yeast.

After laughing out loud and having my colleagues look at me strangely, a moment of seriousness hit me. What if the "gummygoo" pattern is not a star pattern but the molecular form of the 'Ultimate' beer, a beer that would appeal to everyone? A beer that EVERYONE would HAVE to drink. Should someone warn Budmilloors? This is the first time I have heard of a fermenter, full of wort, being abducted by aliens (other than the episode of the X-files where strange bright lights were seen over the New Haven Brewery and a 60 barrel fermenter was ascending into a UFO).

Date: Mon, 19 Jun 1995 10:03:22 -0400 From: hbush at pppl.gov (harry) Subject: Re: Liquid Yeast Experience James Drago would like some advice on using a smack-pack of yeast that took 6 weeks to swell. From my limited experience, I would say; 1) Sounds like a strange yeast packet 2) If it's a strange yeast packet, don't use it! Why gamble your time and the expense of a batch of beer on a dubious yeast? HOWEVER, it sounds like a great oppurtunity for a little experiment. Pitch the package into a pint starter. After the starter ferments out, taste it. Taste should tell you whether or not the yeast is OK. If its good, pitch the sediment into your next batch, or better yet, make a quart starter and pitch the sediment from that into your next batch. If it tastes bad, congratulate yourself on not using it in your beer!

Smaller than 2 litres, with a nice cathedral motif on it. Most have a metal handle with 2 holding straps, but this growler had a ceramic handle molded to the vessel. I filled the bad boy with a weizen and on the 7th day it EXPLODED atop of my entertainment center. I got paranoid so I took all 75 bottles of the nitro and put in the crawlspace. So far, none have gone off. 2nd part of this disaster is that her mom packed 2 of the bottles in her luggage to take back to Germany. One broke en route (She still loves me though). Question: Are these growlers filles just like my 16 oz. bottles, or is there some special procedure I don't know about. BTW, I primed w/ 1 cup sugar in about 4.5 gals. and left 2" of headspace in growler. Mike Return to table of contents

Date: Mon, 19 Jun 1995 11:44:40 -0400 From: jds at equinox.shaysnet.com (John Shearer) Subject: efficiency/storage Greetings! Three quickies for the collective: First - Concerning lautering efficiency. How do I determine it? What is considered good? If it's bad, what are the common problems? Is there a FAQ? (I looked, and I didn't see anything in the grain FAQs on this subject.) Second - On storing beer in bottles for an extended period (several months). I prefer to force carbonate, but I also like keeping my kegs freed up. If I force carbonate and counter pressure fill, how long will the beer last in the bottles at room temp / cellar temp / or fridge temp? (I heard somewhere that if you don't 'bottle condition' the beer it won't last as long in the bottle.) Third - Regarding dirty deep frier grease. I accidentally dumped approx 3 quarts of dirty grease from my deep frier into the boiler. I didn't think much about it at the time, but it made a congealed mess in my primary! I was out of fresh mercury to clear it up, so I didn't do anything. IMBR? Any and all replies would be appreciated (on the first two questions anyway :-). I will post a summary if response is good.

One of the differences among people arguing this issue is the distinction between all-grain and all-extract. I submit that it is a wide continuum between: 1) Opening kit can, pouring contents and tap water in bucket, pitching yeast. and 100+) Harvesting yeast from sample, including microbiological analysis, growing and malting own grain, etc, etc. Also, I submit that bottling/kegging is a separate issue completely. My own personal data point: I had already switched to a wort chiller, full volume boils, adding hops, making a yeast starter, and steeping grains. To go from this to all-grain I had to mill grain, mash, and sparge. Nothing else changed in the least. Milling grain takes ten minutes or so. Mashing can take from half an hour to who knows what (lots of different temp rests with a Wit). Sparging takes about half an hour or so (I heat up the sparge water while mashing). So, my personal status is that all-grain takes at least an hour more than extract. If you have to start wort chilling or full-volume boils or whatever, your delta may be larger.

I'd like to include some information in our monthly newsletter to help out brewers who are using kits, and would like to gather information on what "good" ones are out there on the market. I know of one because I recently tried an excellent bitter brewed by a friend of mine (George Schnurle). He used a kit from Brewmaker called "High Quality Victorian Bitter." Besides producing a quality product, please include in your recommendations other good qualities, i.e. good instructions, good materials, price, availability. Thanks!

Date: Mon, 19 Jun 95 12:47:04 PDT From: Rob Emenecker <robe at cadmus.com> Subject: cf chillers, hops, propane cookers Jay Reeves (w/ responses from Bill Szymczak & Rob Reed) asks about hop utilization with cf chillers.... I have finally bitten the bullet and built a cf chiller. I plan on using it with my next batch. Up to now I have only done partial boils and chilled the wort in an ice bath. I agree with Bill that the difference between immersion or cf chillers will be neglible. I expect to see a profound difference (i.e. better aroma and flavor character) when I switch to the counterflow chiller (not to mention better utilization by doing full boils instead of partials). As a side effect I am also hoping to reduce the amount of cash I lay out for hops (can reduce boiling and finishing). .................................. Chris Barnhart.... My envelopes with *TWO* stamps is in the mail. .................................. Rick Gontarek asked about propane cookers.... I saw a King Kooker at Sam's Club that had a needle valve set just behind the regular on the tank side of the gas line (which is supplied with the cooker). I don't know about the Cajun Cookers, but if you a reasonably mechanically inclined they are easy to install (don't forget to check for gas leaks). These needle valves provide great control over the flame. The one troublespot is good ole' mother nature. If it is a windy (or even breezy) day outside, getting a consistent flame (read: temperature control) can be a royal pain in the but. I tried making an American Wheat one breezy day and was jumping between boil overs and no boil for damn near 90 minutes. I ended up with a brew that I "learned" to drink (my father and father-in-law referred to it as Rob's American Methane Ale!... ooh what an aroma it had). .................................. To the Borg (err HBD) collective intelligence.... Although I can do chemistry and physics if my life depended on it, it is not my favorite pasttime. That said, do any of you metallurgy folks know of a good text (regarding the interactions of metals) that will not require me to good back to college for another two years of chem and physics. The reason I ask is simple. Now that I am entering into homegrown gadget heaven, I want to make sure all of my parts are compatible... an aluminum stock pot, stainless steel sparging screens, brass valves, copper counterflow chiller and racking cane, etc. Yes, I know that these are all separate items, but I want to try to connect everything together in an assemble line fashion (Henry Ford are you out there). What I would end up with is an aluminum stock pot with a brass nipple valve fitted into the side (using gaskets, nuts and bolts, whatever it takes, but NOT welded), a stainless steel filter screen fitted over the inside of the valve (is aluminum an option here?... I can get aluminum lint screens that would fit perfect, but I do not know if they are a good idea). From the pot valve it will connect to a dishwasher supply line (tubing with stainless steel braided covering) to the copper compression fitting into the counterflow chiller. (Sorry folks no ascii art). Whew! Well, is it "do'able" or will I get into problems at the metal-metal contact points? ============================================================================ Rob Emenecker (remenecker at cadmus.com) Cadmus Journal Services, Inc., Linthicum, Maryland 21090 410-691-6454 (voice) / 410-684-2793 (fax) Date: 06/19/95 Time: 12:47:04 - ---------------------------------------------------------------------------- "There are only two things in life that are ever certain... taxes and BEER!" ============================================================================ Return to table of contents

You definitely DO NOT want to pour the wort through a funnel. At this stage you don't want to add oxygen to your wort, as that will cause off flavors in the finished beer. At every transfer stage after fermentation has begun, you want to siphon carefully, making sure the siphon outlet is at the bottom of the receiving vessel (to avoid splashing). Personally, I would get a 5 gallon carboy for a secondary fermenter. However, if money is tight, I would use the bucket to avoid having to transfer the beer twice. I hope this helps.

Date: Mon, 19 Jun 95 13:33:53 EDT From: (Art Steinmetz) Subject: Hose for Steam, Steam Generator Usage I got many helpful replies to my original post regarding the use of auto shop silicone vacuum hose for a steam infusion mash system (SIMS). Thanks to all. None of them said "no problem. Use it." The fact that after running a couple gal. of water as steam through it a chemical odor persisted led me to reject it. Another suggestion was braided water hose like that found in kitchen sink squirters. I happened to have some surplus from an old faucet. It appeared to be vinyl with a braided sheath. It got too soft and limp at steam temps. Robert Brown did report good results with similar hose, though. One poster suggested polypropylene, a harder opaque white plastic. I haven't found any to try yet but will keep looking. The always helpful Spencer Thomas suggested the Cole Parmer catalog (800-323-4240). They have braided silicone tubing which is rated to 150 PSI for $300/25ft. Mark Stevens in HBD 1748 provided a nice table of tubing specs from US Plastics (800-537-9724) which I won't repeat. They have 3/8" ID silicone tubing for $96.36/100ft. For the moment I'm using copper for the whole length. Like John Dodson I can report a good experience with this system. The Clyde Crashcup Brewery (now Steamworks and Brewery) got cranked up last weekend. The precise temp control and only slight change in water/grain ratio are the attractions. I got a temp increase of about 1.5 deg. F. / min for 8 lbs of grain and 3 gal. of water. The drawbacks are that you have to constantly stir the mash during the steam application and that grain bits clogged some of the 1/8" holes I drilled. TIP: turn the steam on and off while the tube is out of the mash. I had a loop of 36 inches but the pressure drop by the end of the loop made most of it superfluous so I cut the outflow section back to 12". I have had a hard time in the past hitting precise step temps with boiling water infusions and have had to add too much water when ambient temps are below freezing resulting in too thin a mash. This rigs solves both those problems. Recommended. - -- Art asteinm at pipeline.com 76044,3204 at compuserve.com Return to table of contents

Ray Robert <rayr at bah.com> writes: >I wanted to ask the masses what their thoughts were on the idea of bottling >the yeast "sediment" at the bottom of the primary fermenter for use at a >later date. Can this be done easily and successfully? Yes. Most people collect the sediment from the secondary as it has much less trub and crud in it. However, in repeatedly collecting the sediment from the secondary one would be selecting for less flocculent yeast, so it might be good to go back to the source after a number of generations. I pour a 1-2 pints of preboiled, cooled water into the secondary, swirl it around and collect it in a sterile container. Then I "wash" it 3 or 4 times by letting it settle, decanting, adding more preboiled, cooled water, decanting, and repeating. I end up with an inch or more of pure white yeast cake on the bottom of a 1000ml flask. If you are going to store this in your household refrigerator, which are microbially filthy places, seal it well and place in a NEW ziplock bag. Before opening, sanitize the neck of the container. I invert the stoppered flask in iodophor, then just before opening flush the neck and stopper with 70% ethanol, but then I am anal about sanitation of my starters. See the yeast FAQ. Some people "acid wash" their yeast with a pH 2.5 phosphoric acid solution. Suspend the yeast in the solution for 2 hours then rinse repeatedly as above. This will kill bacteria but leave the yeast unscathed. >Also, I ran across a product called "Marmite" in the Bread yeast section of >my local grocery store.

This sounds suspiciously like Vegamite, a vile, black spread from down-under which I unfortunately had the temerity to try while in Sydney dining with Dave Draper, Chris Pittock, Andy Walsh (congrats on your Best Brewer status) and Ken Willing. Although fine fellows all, I think they pulled one over on me, because NO ONE could actually enjoy Vegamite. It must be a continent-wide Aussie practical joke played on the rest of the world, and actually no natives eat the stuff, but by law every household must have a jar for visitors. Anyway, Robert, try it, but in all fairness you must try it repeatedly, because I hear that it is an acquired taste. >;-> Domenick Venezia ZymoGenetics, Inc.

Date: Mon, 19 Jun 1995 12:23:41 -0640 From: FLATTER%MHS at mhs.rose-hulman.edu Subject: Re: Chocolate brew Robert Mongeon <rmongeon at together.net> described his chocolate brew where he added 16 oz of Bakers chocolate to a 10 gallon batch like this: I pitched with a good quart of Wyeast Ale mix that was at the bottom of another batch that I kegged at the same time. I also added a packet of Nottingham dried yeast just to be sure that fermentation got off on a good start. Well, it has been 24 hours since I pitched (at 70 degrees) and still no sign of fermentation. I did notice alot of residual oil on the top of the batch which was probably due to the chocalate. I wonder if anyone else has had the same problems brewing a chocalate beer. ++++++++++++++ Actually, I just finished researching the effect of methyl xanthines on fermentation. There are three chemical compounds in this group that we all refer to as caffeine. Chocolate actually has none of the chemical called caffeine, but contains noticeable amounts of theobromine. What I saw in my tests was that the generic ale yeasts, like the Nottingham dried yeast, didn't notice the caffeine, but went ape over theobromine. The lag time was much shorter when theobromine was present than without. In addition, the time period of active fermentation was reduced from three days to two. There was also some clues that imply that ester formation was also reduced. Oddly enough, bread yeast does not seem to be influenced by either caffeine or theobromine. Theophyline produces similar response. The down side was that methyl xanthines also accelerated the aging process, reducing the amount of time I could keep the beer before noticeable oxidation occurred. In plain, brewer's English, the addition of chocolate should reduce the time it takes for the yeast to get started. It should also cut back on the time your beer should spend in the primary. The oils from adding chocolate instead of cocoa or pure theobromine increase the lag time for active fermentation. Chocolate also reduces the length of time your beer will keep. In order to avoid a technical response, I have left out many of the details involved. If it is of interest, I'd be happy to share the details of my fermentations, stimulant concentrations, and ester analysis. - -------------- Neil Flatter Rose-Hulman Institute of Technology Chemistry - Math Chemistry Facilities Technician Novell Supervisor 5500 Wabash Avenue 73 (812) 877 - 8316 Terre Haute, IN 47803-3999 FAX: 877 - 3198 Flatter at Rose-Hulman.edu Return to table of contents

Yes, if you have a cover and fermentation lock for it but If it were me I would either use the same glass carboy or buy another one. I have a 6 1/2 gal primary and a 5 gal secondary (both glass) that I use. If you really want to use the bucket as one of your fermenters, I would recommend using it for your primary as the beer won't be in it as long and you *can* if need be do your primary ferment in an open container. >3) Should I just buy another carboy ($)?

Date: 19 Jun 95 15:18:29 EDT From: Ray Daniels <71261.705 at compuserve.com> Subject: Food vs. Beer Grade Extracts On the subject of extracts: In HBD 1757 Edwin Thompson says: "I was also warned that DME is not always appropriate for brewing since it is often food grade while the LME for brewing is the actual beer grade." In HBD 1759, Pat Maloney (patrickm50 at aol.com) responds: "But I thought beer WAS food! Who told you otherwise, Ed? Is 'beer grade' better or worse for you than 'food grade'?" I assume that DME and LME here refer to Dry Malt Extract and Liquid Malt Extract. This is only a little confusing since the initials DME are often used to refer to Diastatic Malt Extract which retains some enzyme activity. (Maybe no one is using this stuff anymore.) Yes, beer is food -- unless of course you consider all the special regulations that apply to the manufacture, marketing and consumption of beer that don't apply to most foods. Let's face it, in the U.S., alcohol is treated like a drug. But that is a subject for a different post . . . The real reason for this post is that I spoke with the representative from Premier Malt during the National Homebrew Conference. She(!) mentioned that they DO produce a separate (dry) malt product for cooking non-beer foods that is different in character from the extracts that they market for beer making. This food extract is sold under the "Dia Malt" brand name, while the beer extracts are found under the "Reserve Gold" brand. In the Winter 1994 issue of zymurgy (page 38) you can see some of the differences that may occur in food grade products. In the case of Dia Malt, the free amino nitrogen (FAN) level is markedly lower at 163 ppm than that found in other dry extracts which range from 203 to 225 ppm. As FAN is an important nutrient for yeast in the making of beer, the Dia malt would be much less desirable for this purpose than the other products reviewed. In addition, the carbohydrate composition -- that is the balance between the various fermentable sugars such as glucose, fructose, sucrose, maltose, etc. -- may be quite different in extracts intended for food and beer. This balance also makes a big difference in brewing and you may find less desirable mixes in the products intended "just" for food production. Finally, both the Premier and Northwest extract reps indicated some trend toward more extensive labeling of their products with information like color, FAN and carbo composition -- if not on the package then at least with accompanying or available literature. Let's hope they follow through. Who knows, maybe we'll eventually get enough good information on extracts that even the all-grainers will feel comfortable using the stuff now and then!
