Rod (beerdog) asked a few posts back asked ... >3) back to the rye tread for a minute, rye, i beleive was aleged to have >the same precusors to that clove-like character we all know. am i correct >in this? also, does rye have the same head retentive properties as wheat? >my experience leads me to beleive it does not, however, i may not have used >a sufficient quantity. The presence of the enzyme that produces ferulic acid from malt in rye is speculative, but my 63% rye beer does have a substantial clove (4-vinyl guaicol) component, and I'd guess that the amount is similar to a barley beer using this yeast. Don't know - good bet. As for head retention - rye doesn't have the heading capabilities of wheat but has much more than barley malt. Rye falls between wheat and barley here. Rod also asks ... >4) i still dont know what RIMS stands for. please, help! depending on context ...

I've personally had enough of listening to Charlie Papazain telling about his travels. He is not the President of the AHA anymore, so he is traveling using whatever money is provided by the AOB (which includes the AHA). I think Charlie has gotten out of involvement with the AHA since professional brewing is where the money is. Homebrewers are cheapskates for the most part. Save your money and buy a Pico Brewing System. :-) Also the AHA provides not roommate matching service which can create problems if you want to go and are trying to find a roommate to save some money. National Homebrew Competition The only advantage to an AHA membership here is that you get a discount on entry. But the awards except for the big winner are not all that great. Just because someone wins in the "Nationals" means nothing more that any other competition. A large number of good brewers do not enter competitions particularly the Nationals. Sanctioned Competition Program This is not much. You are much better off sanctioning with the Beer Judge Certification Program. A "sanctioned " competition may or may not be run well so don't be fooled into thinking this means anything. Some at the AHA are not happy that the BJCP did not dry up and blow away. Remember all the talk about the AHA judging program etc? Members Information Service This can be a help to newbies. But after awhile it is pretty useless, particularly if you are the type who reads Brewing Techniques etc. Homebrew Club Network There are plenty of sources of club info now. Various beer rags, homebrew shops, the net etc. Periodic discounts on books published by Brewers Publications This is a joke because they then want to charge $3-4 for shipping an $11 book. You are better off waiting for it to show up in your local shop. A Full Guarantee Which brings me to the point that you can cancel your AHA membership and get your money back or simply not renew. CompuServe Beer Forum The AHA never has had much of a presence on this forum. They were given free access for a while. Essentially most of the sysops on the forum know alot more than the folks at the AHA. James Spence was the only person who even participated on any regular basis. He is gone. GABF entry in to members-only tasting As Kelly pointed out this is no longer a free-benefit. Like AHA members go in such large numbers that they are really going to contribute a large amount of revenue to this thing? I think not. Dilbert in action. Zymurgy Good for beginners. Special issues used to be something you got to use as a reference. Not this year. This magazine is entirely support by the writing of homebrewers. This makes for articles that may need large amounts of editting and correction that is also done by members. There are problems with the editting process for Zymurgy and without the use of e-mail I don't see how it ever got done in the past. This is not to say BYO and BT don't have editting problems either. The AHA powers that be have made no formal mention of the firing of James Spence. Good or bad he was with the AHA for five years. It has been almost a month since he was let go. There are various political reasons for his firing. The details are such that it is best not to discuss them at length since he still has to get a new job. The AHA has not given me any formal response to my queries about this. Some may say it is none of my business. There are those at the AOB who feel that James was an important contact for many MEMBERS of the AHA and that these MEMBERS deserve a formal explaination. The President of the AHA feels differently. It was just decide that James "wasn't working out anymore" and was let go. The Winter issue will have no mention of his firing or the fact that he is even gone, last time I contacted the editor. AHA Board of Advisors This is another joke. The AHA does not listen to them. any suggestions are ignored except for those that follow the AHA/AOB party line. Lifetime memberships I know a person who has been openly critical of the AHA. He refuses to advertize his homebrewing business in Zymurgy. what does the AHA do, they give him a lifetime membership.

So I guess if I don't like the weather I can move. I would again just point out that I do not think it is a good idea to have an internet digest under the control of the Papazian empire. Also I would point out the The Brewery has done an excellent job of providing an extremely useful archive of good homebrew info. But you have to have net access. For a while magazines will be a better means of disseminating info and fortunately there are alternatives to Zymurgy. So I guess it is your own choice whether you think the AHA "membership" is more than just a subscription to Zymurgy. And I still believe homebrewers need to have an alternative to the AHA. Homebrewing has made great advances, the AHA has not. Jim 1994 AHA Homebrewer of the year www.u.arizona.edu/~jliddil Return to table of contents

From: Miguel de Salas <mm_de at postoffice.utas.edu.au> Date: Thu, 24 Oct 1996 08:57:41 -1000 Subject: Plastic carboys Guy Gregory asks what kind of plastic we use for brewing in Australia. Here in Tasmania the easiest thing to get is food grade polyethylene, which is what I have used for well over 30 batches of both extract and partial mash brews without any problem at all. I've had beer sitting in the plastic for up to a month without any noticeable change in flavour. Of course I should point out that I don't brew lagers, only ales. In a lager, which is brewed much colder, there would be the potential for more oxidation, since permeability would increase at lower temperatures. Also it would be much more likely to notice an off flavour or oxidation in a light flavoured lager. Cheers. - --------------------------- Miguel de Salas, in Hobart, Tasmania, Australia.

Actaully the opposite is true for the vertical coil. Colder water at the top cools wort which "sinks", displacing warmer wort to "rise" into contact with the cooler top coils. Running the cold water in at the bottom would result in the cool wort staying on the bottom and the warm wort at the top staying at the top. Return to table of contents

The OG was 1.052. I am bottling tonight (no activity for a couple days) and I'll let you know if its drinkable, however, I just graduated from college, so you might not trust my idea of drinkable! :) I was shooting for a 2 1/2 to 3 gallon batch ... 5.5 lbs 2-row pale 1 lb munich 1/2 lb 120L crystal trace of chocolate malt hops + yeast starter ... and ended up with just short of 2 1/2 gallons.

From: Alan <amf at ktb.net> Date: Wed, 23 Oct 1996 15:39:14 -0700 Subject: Optimize my Oatmeal Stout Brew enthusiasts, I humbly submit the following for comments and suggestions. Re-creating a successful oatmeal stout recipe that my brew partner and i had made last year, we used: 29# klages 1.5# black patent 1.5# Belgian chocolate 1.5# Belgian roast 2# flaked oats some northern brewer (i think) bitter small amount fuggles flavour 1/2 gal Wyeast London ale starter Lately i've been adding 1 tsp gypsum per 6 gals of RO water used (sparge water too). Added 160f water and re-circulated with a heater to 150f (took about 30 min). Noticed ph was quite low (about 5.0 or less) probably due to excessive dark grains used. Re-circulate, don't worry, drink homebrew, maintain 150f, eat pizza, smoke cigar, for 2 hours (RIMS are cool). OK, back to work. Increase temp to 168f and sparge with 170f water. Boil 90 min. reduce to 12 gals at SG 1.075. Chill to ~70f, pitch. In an effort to improve my yeast performance (attenuation) i've been experimenting with aeration. So, this time, i used the aquarium pump for 8 hours (no stone, hopefully filtered air). As i removed the air, the foam was just starting to come out of the top of the 15 gal bucket air lock hole. While by brew buddy bailed foam, i rushed out and got some 1 1/2" blow off tubing. The air temp was 70f but the foam felt much warmer squishing between my fingers. After 12 hours the volcano subsided. Week later SG was 1.023. Another week, still 1.023. Tastes great flat and warm out of the fermenter. Would like to improve the following: lower FG (too sweet), better yield, final yield (lost a lot of beer due to foam!) TIA. al Haphazard Brewing Costa Mesa, CA Return to table of contents

This sounds backwards, but his >explanation was that the chlorine that produces the smell is combined >chlorine. Free chlorine will chemically neutralize combined chlorines and >the odor. Just how is getting out of my area of knowledge. I have also been told that when you can smell chlorine there is not enough in the water. The explanation I heard was that when there is not enough chlorine in the water to kill the bacteria they absorb it and when they die (and presumably rot) it is released and we can then smell it. Strange but true - I think! I have also been told that as chlorine is a gas if you just leave the water sitting there without a lid on the gas will just evaporate off. I think it was John Carsten who wrote that the chlorine is bonded with ammonia so this may stop the evaporation from happening. I don't know if that is true or if all chlorinated water is "bonded". Even if it is bonded, if it is the rotting bacteria that produce the smell (& taste?) maybe that makes a difference. Over to you experts. P.S. Definition of "Expert" (pronounced "Ex-spurt" of course): An "Ex" is a "has been" and a "spurt" is a "drip under pressure". - ----- Yeast: Bill Graham asked about which part of the yeast solution to use. I wasn't sure if he was talking about a yeast starter or about using the "left-over" yeast in the ferment to start one. If it is the former then I swish it all around and use it all. If it is the latter, I have read people advocating each of these and would like to know which is best too. The guy who said not to use the stuff on the bottom said that this was all the dead yeast that had settle and that the live yeasties would still be floating around. Sounded logical to me.

Last Saturday our power was out so I couldn't work on the computer. I did some on Sunday and Monday was brew day, Tuesday brewing class. SO I now have some time and the phone system is completely gone. The phone line was noisy all weekend such that the modem wouldn't work. My apologies for being so tardy in responding Phil Wilcox' description of how he didn't make pupmkin ale was entertaining and I know how he feels. Some days in the nano-brewery are like that. He said ( after lots of descriptions of lots of things that went wrong): >I feel alot like charlie brown. I had a few problems brewing last night, The >recipie is the Pumpkin Ale posted in Cats Meow................right on schedule. >Proceeded to chill as advised and to my suprise I could'nt >get a decent siphon going at all. Only a trickle. Tried the chorboy, the >inverted racking cane stoper, Whirlpooling...Nada. Painfully slow. 15 >min/gal! I said in an HBD prior to his Pumpkin Ale Production: >Best way is to cool the 2.5 gals of hot wort before transfer ( it is more efficient), siphon it - through a >Choreboy scrubbing pad to strain out the hops and hot break and some of the cold break - into that cold >water, letting the cold wort pass through the air to oxygenate it. Or siphon directly to that copper cooling >coil/ice cooler is the best. I don't understand your reference to the "inverted racking cane stoper", but I have on occasion had problems with siphoning the wort with a Choreboy in place, but only when I let the tip of the cane get next to the outside of the Choreboy. It is impossible for the Choreboy itself to slow the flow, since it is so open. When the cane tip is near the outside of the Choreboy, hops can collect around the cane entrance and slow the flow. The ideal place is for the tip of the cane to be at the center of the Choreboy ( like the center of a sphere) . When you get it going it is an amazingly fast and efficient way of removing the wort down to the last drop and getting none of the hot break or hops over. It can strain wort you can't even see from a pile of hops and trub on the bottom of the boiler. A 3/8" cane is plenty big enough. Avoid putting the cane hard up against the edge of the pot so you don't push the tip of the cane to the outside of the choreboy. The cane tip should be near the outside edge of the boiler, but not pressed against it. Clear the cane tip by letting the wort run backwards through it, adjust the choreboy so that the cane tip is halfway into it and place it on the bottom of the boiler, just off the outside edge, and siphon away. Better luck next time - with everything. Persistence will bring success. I guarantee it. Just say Dart Frog Dortmunder three times when you are getting frustrated and remember you could be doing something like mowing the lawn or shovelling snow. So smile. - ----------------------------------------- AlK says to me: >You are spiraling out of control (as I've done in the past). Get a grip >and start posting only what you know for sure. No disagreement that you have spiralled out of control in the past and appear to be now, based on my observations and comments from others. I would like YOU to get a grip, Al. We ALL want you to go back making some of those excellent contributions you used to make here and knock off this attack mode you have been in lately. Take a vacation or finish your book or drop whatever is bugging you. I bear you no grudge, but wish you would step back a little and get less personally involved in what's happening here. I stand by everything I said. I don't have the advantage of peer review before I submit my comments, so they do have the possibility of being "misleading" to someone looking for an "error". If they were truly misleading or wrong, which does happen sometimes (at least to me), a simple comment will bring an apology and a correction from me. I am not an idiot, nor bad intentioned, nor am I perfect - no matter how hard I try. Weren't you the one who objected to my backing up everything wih a reference? And lately you haven't even believed my references. What's a body to do? Anyway, thanks for your concern. We love you, but the tank is heading toward empty.

From: "David R. Burley" <103164.3202 at CompuServe.COM> Date: 23 Oct 96 21:52:19 EDT Subject: Re: Calcium and pH in wort Brewsters: Please note my phone service has been too poor or totally nothing since that Nor'easter last week so I can't receive HBD or send my comments. Some of the comments below may be a little out of date or overlap others' comments. Sorry. Bill and I continue our thread ( where's everyone else?) on calcium in beer. > If an acid rest works, why not lactic acid? Should work fine. Given your premise, which I have always assumed requires some calcium in the water. > Is the alpha amylase enzyme > stability a function of pH or calcium? Both I believe. But the alpha is unusual in that calcium is involved. > Another question, how much calcium does malt have? M&BS p 194 1st ed says: "In lager brewing, the adjusting of the wort pH is achieved largely by addition of acid to the liquor and/or the partial removal of carbonates to give 50 - 100 mg/l ((aka ppm)) calcium *carbonate* ((or 50X40/100 = 20 ppm {Ca++} to 100X40/100 = 40 ppm {Ca++}))................ The practice in pale ale breweries on the other hand is to to pay more attention to the addition of gypsum, although removal of carbonates is often carried out.........Gypsum is added to the brewing water to bring the calcium ion to 50 mg/l ((aka 50 ppm)) and a further charge of gypsum is made to the copper, equivalent to 50mg/l of calcium because too high a level of calcium ions in the mash is disadvantageous........ The concentration of calcium in beer will be on the order of 60-80 mg/l ((60 - 80 ppm {Ca++} ))" (( my comments)) I cannot find an analysis of malt or barley that gives me a calcium content, and it not is obvious from the above comments that the malt is supplying any. In the absence of any information to the contrary, and based on the need for calcium to stabilize the alpha amylase in mashes where acid rests are used, I would guess the malt is supplying 10-30 ppm of calcium to the beer. This would explain how acidifying the mash with either an acid rest or lactic acid would get the {Ca++} in the 20-40 ppm range ( when you add in, say, 10 ppm from the water) used in lager brewing. Let's try thinking of it this way: Any phosphate that is available will definitely precipitate the calciuim, since the insolubility ( something on the order of 10^ -33 as a Ksp) is such a force in removing calcium and phosphate. Now, if there is an excess of calcium and we add more phosphoric acid we wil get more calcium phosphate and the protons from the phosphoric acid will remain in solution. If we don't have an excess of calcium we will still get acidification. If we have an excess of calcium and the pH is still too high, it will mean the total amount of naturally occurring phosphate is all gone. Yeast need phosphate. Adding an excess of calcium to the point of getting a pH of 5.2 or so must not deplete the natural phosphate content. The mechanism is different with lactic acid, since the calcium salt of lactic acid is pretty soluble. Therefore, the lactic acid will not strip the mash of calcium (needed by alpha amylase) and should be better at providing the proper mash pH and leaving calcium in the solution for a more stable alpha amylase ( hence a more efficient mash is likely), better flocculation of the protein breaks and flocculation of yeasts at the end of the fermentation. My vote goes for lactic over phosphoric acid. In the course of reading aout this I came across reference that is a little off course, but it relates to better beer and puts in a vote for acidifying the mash with lactic acid. M&BS p209, 1st ed. "The flavour of the beer is altered by the quantities of chloride (full flavor) and sulfate (dry flavor) and lactate (softer flavor) ions that are present in the mash." The first two (Cl, SO4) I was aware of, but until now, I don't remember seeing a reference to lactic acidifications producing a "soft" taste. I did notice a softer, less dry, taste, however, especially in my IPAs, which are Burtonized, when I began using lactic acid to acidify my sparge and at the time assumed it was due to a reduction of husk tannins. This sounds like acidification of the mash with lactic acid could be of benefit for beers like some lagers, German and other beers which benefit from the full, soft mouth. It may be out of place in the firmer mouthed, drier pale ales, etc. It would be interesting to make a low calcium, low sulfate, high lactate pale ale and see what results.

If so, when it is better to use, > if not, why? Brian, You wouldn't be the first HBer to ascribe a higher quality and mystical nature to someone else's tap water. Unless you have a problem with your own tap water, say extreme hardness or high iron content, don't bother. If you have very permanently hard water and want to make lagers, dilute your tap water with distilled water used for drinking. In most cases cooled boiled tap water is sufficient if you are making extract brews. When you make all-grain, brews water quality increases in significance. - ---------------------------------- Chuck Bernard asks 3. If I get one of those vacuum sealers at a garage sale or flea market somewhere I this a better way to store grain than frozen/refridgerated? What about vacuum and cold storage? Chuck, When you say grain, I presume you mean malts? If so, there isn't really a need to do any more than keep them cool (say your basement), in a closed container ( I use lidded trash cans, Rubbermaid storage boxes and plastic shoe boxes) to keep out the mice. They will slowly lose their enzymatic powers, but it will take several years, based on my personal experience. - ------------------------------------ >1) is it feasible to keep the temperature at a constant 155 degrees > in a $1.50 bucket (noninsulated)? NO. Even a 5 gallon mash tun inside a styrofoam box drops about 2 degrees per 30 min. Wrap several layers of bubblewrap around to help and don't forget to insulate top and bottom. Why not use a 5 gallon boiler and mash there. You can heat periodically to bring the temperature back up. >2) if the temp in the bucket drops from 155 to 150 in a one hour > period, is that a problem? It will make a drier beer than one held at 155F >3) if the temp drops to (say) 145 degrees in 30 minutes, is it OK > to pour hot water into the mash to reheat it to 155? Of course, but see above. Adding hot water during the mash speeds up the saccharification by reducing the product concentration which can block enzyme action. >4) for a single stage mash (infusion?) is it necessary to do a mash-in > before the actual mash?

Recirculation is important to prevent any starchy residue from clouding the beer during the boilup. I generally recirculate 1/2 to 1 gallon, reheating to 170F before putting it back into the sparger, depending on how cloudy it looks and how fast it is running. - ------------------------------------------------ Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3203 at compuserve.com Return to table of contents

Hear hear! I'll drink to that...and I will too (got a pale ale on tap in the brew fridge)! 8-) Anywayz, most lists are like that, there are a few folks who post the majority of the traffic and they, due to exposure I suppose, get the heat. I'm an AHA member and president of an AHA affiliated club but, I don't see the source of the "AHA problem". I also don't know the details of the situation or politics (if you must) involved causing the problems. Until those details come to light I'm willing to say thanks for the effort and resources for the digest and leave it at that... > Very easy to say stuff like that, but who gives a shit.

These plates date back to July 1994...over two years ago!! My Wyeast 3068 is dead (well, I restreaked a colony, we'll see how that goes, but a culture tube I've started last friday is dead), as is my chico. I already got a new plate of chico going (looked at the brown colonies sunday, so went to the local deli and got me a bottle of SNPA. Aleady have me some nice baby colonies, not even white yet hehe, but visible with the right light). Enough of my banter, here's what survived. I have a couple of 2+ year old plates that I cultured from Wyeast 2206 Bavarian Lager. The stuff on antibacterial agar is dead. The stuff on my wort agar plates (my wort, chinese agar...a hell of a lot cheaper than wort agar from a science supplier and probably healthier for the beasties too!) is mostly dead but for over a dozen survivors. This plate basically has hundreds of colonies that died while they were small but some must've mutated to brave the cold long winter of two years in my beer freezer at 40 degrees. I cultured one of these survivors on sunday and it's kicking out bubbly and forming nice solid flocculated colonies which I gleefully resuspend etc etc. The stuff's growing in the culture tube at a toasty 80 degrees (I was incubating it with a CSU/DSU to protect it from the cold wave that kicked through here for a few day hehe, I'll be sure to drop the temp as I step it up). My question to any and all yeast experts is: Should I risk a batch of beer on this two year old mutant child of Wyeast 2206? What I stand to gain: 1. Free yeast! 2. Maybe I've got myself a superior yeast. What I stand to lose: 1. A batch of beer! A wasted plate if I decide to reculture this 2206 child and it turns out swill. Cast yer votes!!

First of all, IMHO, if you are brewing ales, does it really matter whether or not the container is 02 permeable? what about open fermentation? what about all the hoopla about aeration using pure o2 or air? There should be absolutely no problem with using a food grade plastic to ferment your beer. I have been using several containers which have a volume to the rim of 8 gallons. I usually use 6 gallon brews. This gives me a lot of air contact with the beer. Maybe my tastebuds are dead, but my beer is not oxidized. I also rack into identical containers for secondary. I usually use 7 to 10 days in primary and 14-21 days in secondary. Absolutely no problems that I can trace back to the containers. Scratches on the containers should be of relatively little consequence unless you trap crud in these areas and don't clean the containers. As long as you sanitize and pitch a good starter you should overcome anything left. Back to the plastics... I would recommend that if you are trying to locate containers, look at the bottom of the potential container. It should have NSF-2 or FDA Approved or FDA Approved Materials, molded into the bottom. NSF (National Sanitation Foundation) approves the materials used and the actual containers molded from the various plastics. The constituents have to be listed as acceptable for food contact by the FDA. Don't under any circumstances use a container that is colored and does not have one of the above approvals on it. There are a lot of paint buckets out there that you should NOT put food into. There were until recently heavy metals used in the colorants. There are probably still a lot of these floating around being used in paint or other containers which are not food safe. Clear or natural white containers are Probably safe even if they are not listed as food safe. If food was shipped in the container, then it should be safe. This is where you may have a problem with the reuse of a container, past odors and contaminants.(pickles) If you want a good container, go to a restaurant supply company and purchase a container. Sorry I went on and on, but I do believe that brewing in plastic is safe in more ways than one, I have dropped a glass carboy while cleaning it, it was empty but shattered into a few thousand pieces. I wasn't cut and I sure won't be cut with my plastic and I bet you can't tell I don't brew in glass. Return to table of contents
