Date: Mon, 5 Apr 1999 20:26:00 -0500 From: "Stanley E. Prevost" <sprevost at ro.com> Subject: Klages Malt Hi, y'all - The American Malting Barley Association no longer recommends Klages barley for malting and brewing, according to their web site. Why would this be? Economics? Low quality grain because of disease? Genetic mutation? Increasing availability of newer and "better" varieties of barley? Is it not the same grain it was when it was recommended? Some maltsters sell "brewers" malt as a mixture of AMBA approved varieties. Some even say it includes Klages. Is "brewers malt" the same concept as "contractor grade" building supplies? We all know what that means. Oh, well. I'm just trying to learn about malt and this is one of the first things I run into. Guess I will have a beer. Stan Prevost Huntsville, AL Return to table of contents

Has anyone successfully cultured it from an unfiltered beer made with it? Because it is highly flocculent, will there be any yeast left to culture? I've heard it has higher than normal O2 requirements. If anyone has used it, how have you dealt with these problems? What's an acceptable substitute if Ringwood is just too much trouble?

Date: Tue, 06 Apr 1999 02:52:04 -0600 From: The Greenman <greenman at sdc.org> Subject: Diabetics and Homebrew. Funny that this should come up. This is probably way off of the subject but..... When I began my love of beer, way back in the (sarcasm) good year of 1995, I happened to be priviledged enough to be in the country of Germany. I foolishly got engaged to a young lass (stupid youth, I guess it always gets us sometime) whose american host-sister was a diabetic. I loved the beers and so did she, but her diabetes made life interesting. My father, who has a passion for beer and wine, is also diabetic, so I was very curious. Beer is loaded with sugars, despite any attempts to ferment the living crud out of it. So some diabetics can go haywire with beer. Anyways, to make a long story short, I got a real passion for this disease and I am attempting to make a research project out of it to finish up my college career. Actually, I'm interested in a type of symptom called "periphial diabetic neuropathy" This is a nasty little bugger that causes people to have strange sensations in there extremities, especially the feet. Some of these include numbness, a feeling of walking on gravel, intense pain caused from the slightest pressure (i.e. a bed-sheet) and a weird sensation described as "both exteme burning and freezing at the same time." This whole nasty thing is caused by sugars that get trapped in the feet or hands, are converted in to fructose, and then again converted in to a sugar called sorbitase (at least I think that's correct, I'm far from my notes and rather scatter brained). Anyway, the whole nasty thing causes the nerved endings in the feet to degrade. Sometimes these things cause ulcers that get callused over that the diabetic never even feels until its too late. Sometimes it goes away, sometimes the diabetic dies with it. It seems to be worse at night. There is at this time no really concrete treatment for it. However, I discovered something interesting. I came across a report about people that work hard on their feet and how they sometimes develop alcohol poisoning in their feet. The sensations are strangely similar to DPN. I got interested an went over my notes (which as noted above are not sitting in front of me) and I found that moderate and heavy drinkers seem to suffer from DPN more. What does it mean? I dunno. I haven't graduated yet. But its food for thought if your diabetic. Or if you have strange sensations in your feet. Sorry if some of this stuff is wrong, outdated, or the terminology is incorrect. Its late and I haven't had a beer yet. :) Greenman - -- .-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-. T.

It is IMHO fuller bodied than Guiness with a more robust character. It has a sharper flavor than Murphy's, and I personally like it better than both. It is available is some pubs here in the states, and it can be acquired in the same type of Draft can as Guiness. Definitely put it in your list of "too do" if you haven't tried it. Oh yeah, It goes great with hearty foods like stew's, and is excellent with oysters. Greenman - -- .-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-. T.

Much cheaper than making it oneself. It's a bit smaller than the $40-$50 chillers at my local homebrew store but it works great and the price was unbeatable. The store was in ? (somewhere in New England) so do a web search, the web page I had doesn't work anymore. Last time I checked the phone number on the web page was correct but they were no longer updating the web page and the prices had increased slightly. If anyone does call and gets a current price, please post. But its worth looking into for those interested in a wort chiller. John Penn Eldersburg, MD Return to table of contents
Date: Tue, 06 Apr 1999 11:26:38 -0400 From: Matt Brooks <mabrooks at erols.com> Subject: Diacetyl Another viewpoint on the Diacetyl discussion...... I (among many others here) am not opposed to some diacetyl in my beer, it is not an offensive flavor in low concentrations, but perhaps my palate is not as discerning as some. It also seems peculiar that the people who seem to despise diacetyl so much also seem to beer judges, perhaps it is a requirement? :^ ) On the same topic (Diacetyl), I was recently getting some lager yeast from my favorite local brewery (Old Dominion Brewery, maker of Tuppers and other fantastic beers) and was discussing the topic of Diacetyl with one of the brewers. He informed me that they were cutting back on the amount of Crystal malt in one of their beers because evidently too much Crystal malt can result in a false diacetyl like taste in fresh (young) beer, although it diminishes with time, they don't have the time to wait and hence felt they needed to do something to resolve the "problem". One may want to take note of this relationship and question the amount of Crystal Malt in your recipe if you are experiencing excessive Diacetyl flavors in your young (<2 months old) beer, and all other factors (good hot and cold break, quick cooling of wort, proper pitching temps., proper fermentation temps, etc....) don't seem to be helping. Perhaps this is why some homebrew beers taste better (cleaner) after a few months of age (if they have a chance to get that old). Matt B. Northern, VA. Return to table of contents

Greetings gurus, I've heard that bleach is a no-no for SS brewpots, but I've never heard why. I'm getting a new kitchen sink this week and was wondering if I should go for SS or enamal. BTW, my usual processing involves filling half of the kitchen sink with a clorox solution and have it ready to sanitize my equipment as I need it. Will this damage a SS sink?

My spouse has had reoccurring vaginal yeast infections for the past 3 months. She consumed approximately 16 ounces per day of my homemade wine for the past 5 months.

Ask for a "beer" in Dublin and you get Guinness. > Murphy's is brewed in Cork. Personally, this one is my favorite, although > that's blasphemy in most circles. I'd just like to add a lttle more info about Murphy's. I toured the Heineken brewery/museum in Amsterdam last summer, and part of the tour showed the kind of malt they use when they make Murphy's Irish Stout. Yes, it may be made in Cork, but it is owned by Heineken. By the way, they use a malt kilned at a higher temperature to create the color and flavor, to no one's surprise. The tour leaders, who were clearly told what to say, didn't know a thing beyond the script, so the real brewing questions were answered with polite apologies. You can get great Murphy's logo souvenirs at the Heneken gift shop, too. - --- John Adsit Boulder, Colorado jadsit at jeffco.k12.co.us Return to table of contents
Date: Tue, 06 Apr 1999 18:18:00 +0200 From: "Dr. Pivo" <irv at wireworks.se> Subject: Diacetyls III: confusing I was not going to take this discussion there, as I thought it would cloud rather than clear the concept. Furthermore, it would further illustrate how muddled my own thinking is on this subject. Having thought I had cleverly side stepped the actual chemistry of this topic, and thereby simplified it, A.J. DeLange (as usual) presented the very correct following: > The honeylike quality Dr. Pivo mentions is usually > associated with 2,3- pentane dione, a simlar "vicinal diketone" > (diacetyl is 2,3 butane dione). Now here is where it gets REALLY confusing for me. The vicinal diketones represent an oxidative state that one would think would be evenly distributed over the family. 'splain this: A good Bavarian Pils tastes to me of a vicinal ketone mixed with DMS. If you will, a combination of honey, corn, and snap beans. This is another one of these wonderful "middle ground" flavours that tie the booming base notes of hop bitterness and malt flavour to the treble of hop aroma (pardon the musical analogy, a well made glass of beer is really like a well played symphony to me.... and few things give me more pleasure than the composing and conducting of that frothy number). (psssst. as a brief aside. If I read this forum enough, I'm sure I'd find out that even the production of DMS is a "mistake".....bloody silly Bavarians). Now if we accept that those chemicals are the authors of the tastes I am percieving, let's add this: If a German Brewmaster made a beer with diacetyl taste in it (butterscotch), they'd stick his hydrometer so far up his hiney that you'd only be able to read past Plato 14. So how to reconcile.... you can make one vicinal diketone and avoid making the other. Beats me. But in spite of that digression, I have dug up the old discussion on intentional diactyl production that took place on RCB. I find I did a lot of repeating of the "ranting" I've done here, but I'll try and snip out the practical "how to" parts, since I've already done more than my share of venting: I'll post it as soon as I figure out what a "char" is Dr. Pivo Return to table of contents
Date: Tue, 6 Apr 1999 10:58:54 -0400 From: Dave Burley <Dave_Burley at compuserve.com> Subject: sulfite/aldehyde, gelatin, outfitting, dry stout Brewsters: AJ De Lange misinterpreted my comments about carbonyl compounds forming complexes with sulfite. These complexes are not volatile. In many of the higher MW carbonyls these complexes were used as a method of identification and purification by crystallization in the days before chromatographic purification became useful on a large scale ( i.e. most of the history of chemistry). - --------------------------------------------- Russ Hobaugh produced a good beer on his second attempt (Great!) but had some deposits on the side of the bottles which riled up during pouring. He also used gelatin with some difficulty at botttling. Chances are those deposits are gelatin/yeast deposits if I understand how you used the gelatin. To use gelatin 1) wet it out in cold water 2) bring it just to the boil and let it stand for 10 minutes unheated 3) mix in a small amount of beer into the gelatin solution until you get a fluid solution 4) put this solution into a carboy 5) Rack your beer onto this 6) avoid splashing. 7) Bottle in a few days to a week Gelatin ( a protein) reacts with the hop tannin and other phenolic groups, including any of the hops tannins which have attached themselves to the walls of the yeast. This, along with any charge neutralizatrion, brings down the yeast to produce a yeast-free beer. The danger is that you will add too much gelatin, since it is a very difficult thing to know how much on small quantities of beer. Too much gelatin can produce a hazy appearance but more importantly, gelatin is removing many of those wonderful hop tannins and ophenolics which you want in a beer. Adding excess gelatin can produce a beer with no life,so I never use gelatin. Given time ( something we all understand a newbie doesn't have!!) beer will clear by itself, in most cases, and if it doesn't, you should go back and look at your procedures. Such removal of the yeast will make it difficult to get carbonation and you should add at bottling an active starter plus priming or kraeusen starter I've described in the past ( see the HBD archives). In this case, you probably did not remove the yeast, so you got good carbonation To reduce the amount of yeast in the bottle but still get good carbonation, you should rack from the primary fermenter when the fermentation slows ( 5-7 days) to a secondary carboy to allow the beer to finish fermenting and throw a deposit. When you bottle in a week or so the beer will be somewhat cloudy but light will come through. This amount of yeast will be sufficient to provide carbonation, but will only make a paint coat of yeast on the bottom of the bottle, which you can avoid in your beer during drinking by not pouring out he last half inch or so. Store the beer in boxes or paper bags to keep the light away from the beer. Welcome aboard! - ----------------------------------------------------------------- Brett Spivy asks for recommendations on making beer on the cheap, but not too cheap. And not too complicated since his dumb brother-in-law will do the work. Brett, others might disagree, but, I would buy two cheap 4 gallon SS pots from K-Mart or similar, buy ( or beg) a white food grade bucket or garbage can 6+ gallons, a plastic sheet to cover it, rubber bands to daisy chain and hold it down, a 5 gallon glass carboy for your secondary, some clear 3/8" and 1/4"hoses from your hardware store, an airlock and cork for the carboy, a floor capper. This should get you through the extract stage. If you want to do all grain, I suggest a Gott or similar cooler for your mashtun, if you want to do only single infusion mashes ( although multiple temperature infusions can be done here also) or a 5 gallon or larger cheap aluminum pot for mashing if you want to heat periodically. In the latter case, get a 4X8 sheet of polystyrene insulation and build a box in which the mashtun can be stored for the various rests or use your oven. Make or buy a large wooden paddle, which has a polyurethane coating, for stirring. Get a cheap SS thermometer from the hardware, supermarket or cooking supplies. Calibrate it over the desired temperature range. ( see the archives). Rather than just cooling the boiler pots in a cold water bath with gentle stirring, a counter-currrent chiller made from a 50 ' 3/8" copper tubing and 1" garden hose and Phil's Phittings ( or make your own) would be a great addition. - -------------------------------------------------- I have had an additonal thought or two on Dry stouts. It used to be the practice to add stale ( i.e. sour) beer to stouts. Guinness may or may not do so today. I can attest to the fact that some decades ago it was still the practice, since I have had some pretty smelly (sort of a sour dishcloth) pints which I attributed to spoiled beer, but didn't know at the time that it might have been planned at the brewery. I recall that somewhere in my readings (M&BS?) that Guinness added up to 3% of stale beer to their beer. Such lactic - among others - acidity would produce an additional complexity which may or may not also be added to sweet stouts. I have prepared soured beer, as have others, in making stouts ( see the archives) but I never found it to be a dominant factor in the flavor profile and I certainly did not produce that Guinness factor - yet. - ---------------------------------------------------- Keep on Brewin' Dave Burley Return to table of contents
Date: Tue, 06 Apr 1999 18:33:24 +0200 From: "Dr. Pivo" <irv at wireworks.se> Subject: Diacetyls IV: Got'cha! 09 Jan '99 (RCB) Tony Barnsley wrote: > OK Dr P, Here's another chance for you to be really boring > How do you increase the level of Diacetyl in the beer? OK, I guess you've pulled my cork, as it is an area of interest for me. It is a very good question, and one which I wish I had some good advice for. I don't think I do. <snip> I think the truth is that each yeast strain will pitch diacetyls under different conditions and you'll have to find out with yours what causes it. John Heubel wrote: > under-oxygenating the wort (homebrewers generally do this anyway) > chilling quickly after the ferment to shock the yeast into dormancy > late aeration (like when going to secondary) > under-pitching I think this is a reasonable list to start with (except for the last one - "under pitching" seems to be all the rage now in explaining a host of brewing problems.... every one talks about it, and no one does anything about it - it would really be some simple stuff to set up and test, ferment at different pitching rates and then run it through a blind tasting - but I read of nobody doing it, just talking about that "under pitching" can be found at the source of all problems between a broken buggy wheel, to deficits in the national budget) Oh boy, I'm really foaming now, huh? I would like to make a few comments on John's otherwise fine list. I think the degree of oxegenation, and WHEN it is introduced is one key factor. I've personally never noted underoxygenation in itself as a contributing factor, but that doesn't mean it isn't true of some yeasts. As to late oxegenation, some people have attained diactyls by "dropping", that is, when the krauzen reaches it's peak, you rack it over to another container doing a lot of splashing. This gives the yeast an oxygen burst in the most productive part of their simple sugar metabolism and seems to work with some yeasts. not mine. What has been most consistant for me is a bit similar in theory. It is long, slow, open primaries. I keep them covered with a lid, that has a hole in it with a filter stuck in the hole (well, OK, it's really a bit of toilet paper, but when I first started doing this it really WAS a sterilized filter, honest.) If you let the thing sit about two days after the head is fallen, I don't think the "blanket of CO2" theory holds (and in fact never "really" holds absolutely, making closed and open ferments inherently different), and the yeast will be nibbling at small bits of introduced O2 late in the primary. If you find this works with your yeast, I would then rack VERY carefully and anaerobically from there (it's a hair line edge between making oxidative products you might want - a diketone here, an ester there - and tipping over into things you don't want - the dreaded Al D. Hyde - which once there, NEVER turns into Dr. Jekyl again). The chilling thing works for some people. Making the yeast drop like a stone, I think preferably already at the end of primary. I haven't played so much with that. In general, temperature will be very important. I can tell you that Edme, for example used to throw them at EXACTLY between 9-10.5C. That is until August of '97, when the batch I recieved suddenly doesn't. I've been playing with this "new" Edme, and get a blush of it at a 7C primary and a 5C secondary, but nothing like what I used to attain: "Fermenting an Ale yeast at a primary of 7C??!! This guy must be nuts!!" A last category, that is usually ignored here, is the metabolites the yeast have access to other than oxygen. This is steered most, I think, by trub composition and exposure. If you really want to bore yourself, punch up....http://www.magma.ca/~bodnsatz/brew/columns/jirvine/trub.html I didn't bring up any taste descriptions there, 'cuz I thought it would just cloud the issue, but here are some relevant ones... In the second 'spurment there is "double trouble" and "no trub". These were identically oxegenated, pitched, and fermented at the same temperatures. One had a "double portion" of cold trub, and one had none. The extra trub version had a lovely delicate diacetyl tone (which among other extra complexities of flavour, is I'm sure why it was voted best... all of my tasters have been to Czecho and love that stuff). The trubless one, on the other hand, had some very light and complex estery tones (which just to confuse things runs contrary to the theory of lipid effects on ester formation... hey, what's a fellow to do?). I guess my best advice on how to create diacetyls at a controlled level, is just to always split your brew into separate ferments. If you stick with the same yeast, and try and vary the things either John or I suggested between the two (why not three?) batches, you should soon figure out just what conditions your yeast likes to infuse a predictable diacetyl tone. If you are like me, and think that a diacetyl taste by itself is pretty sickening, but also think that an overhopped beer, with nothing to support it is uninteresting, you may well want to know during the boil when you add your hops, just how much diactyl you're going to end up with.... they are a brilliant marriage when in balance. Addendum: I know what your thinking. If you get a level of diacteyls higher than your hopping rate, why not just dry hop up to match them? Been there, done that. I don't know why it doesn't work, but everytime I've tried a late dry hopping it causes them to dissipate.... just one more level of confusion (?) Dr. Pivo - ------------------------------------------------------------------ Back to the present... since people like numbers, and I did give some useful temps with Edme, I might mention with my lager yeast (Huerlimann, Swiss production) the schedule that "works" is 8C primary (open; and let the head drop) 4C secondary, and in the keg, two weeks at 6C, then chill it down. On a commercial level with Weinstephan 34, the temps are completely different, but that's a "secret", and I'm not supposed to tell. I know people like numbers and recipes, but I'm warning you, these temps in all liklihood might NOT work for you, since we have different compositions of our wort to start with... but if you're looking for a predictable diacetyl level, this might give you an idea of some places to start looking.

Brett, If I were you I would buy a starter kit (sold at every site on the net and at every homebrew shop) that includes at least a plastic bucket, a glass carboy (5gal) and a bottle capper. However, you will be better off with two glass carboys, one for the primary fermentation and one for the secondary. This should cost you in the neighbor hood of 60 to 75 dollars, possible more if you get two carboys. This also includes the first batch, usually. Next, you will want to get a pot. I used a 16 quart stainless steel job that I still use for quick partial mashes. They cost in the neighborhood of 20 to 25 bucks and will work just fine. So, for a total of 100 bucks you can get a functional set up going that will work great for extract batches. After that, a simple investment of as little as 15 bucks you can do partial mashes which will give you an immediate improvement in the beer you make (IMHO). Hope this helps. If you have more questions just email me. ************************ And a few questions of my own. 1. The homebrew shop owner I talked to suggested using a grain bag for sparges. Has anyone had success with this setup or is it inferior to other setups? 2. The owner (and many people on HBD) also suggested using an overnight mash to shorten brewing sessions. So, on my second batch (an IPA with 11.5# grain in 5gal Gott) I mashed overnight (12hrs). I started my sparge and the sparge never cleared substantially. After about 2-3 gallons it did clear but not after the grain bed fell to 110 degrees. So I removed the grain bag and heated the sweet wort to 170 and placed it back into the grain bag raising the grain bed to 150 or so. To make a long story short, I had to repeat this process 3 times because of either a stuck sparge if I ran the runoff to fast or drastic drop in temp if run to slow. I think the problem may be soggy husks due to overnight sparge or possibly too much grain for this system. WHAT CAN I DO DIFFERENT? I don't want to have to throw away 11.5# of grain again. I hate crying . . . . TIA to the collective. Return to table of contents

That rant was a good strawman, but please, let's recognize it for what it was. I don't think you'll find many people issuing across the board bans on diacetyl in every single beer produced. I *do* think you'll find people who don't like much (if any) diacetyl in many beer styles, and I daresay you'll be able to find a few people who don't like detectable diacetyl in any of the beer they drink. But that's merely personal preference. There's absolutely nothing wrong with somebody asking about how to keep the diacetyl level down in the beer they brew, and for others to give advice in helping them meet their personal brewing goals. Let's not try to pressure people into brewing what they don't like just because we might happen to like it. - -- Joel Brewing DMS-free (but sometimes diacetyl-laden) beers in corn country, Illinois Return to table of contents

That is exactly what Big Brew is all about - Promoting Homebrewing! Let's face it, homebrewing is all about grassroots. Most of us learned to homebrew, or at least improved our homebrewing skills, by someone else, a mentor, teaching and showing us how. In return, many of us have taught others. So, if homebrewing is a grassroots-propagated-hobby, how does the AHA, a national organization, fit in? I believe the answer to this question is that the AHA needs to support and facilitate the grassroots efforts that homebrewers contribute in their local communities. Big Brew accomplishes this. We have organized an international record-setting attempt that will "push the buttons" of local media. But in each participant's town, they are Big Brew. Each participant can design Big Brew to fit their area. That's the whole point. We want you to take credit for the record in your area. We want to promote that you are the experts and anyone interested locally in homebrewing should go to you. This is the best way to promote good, quality homebrewing. Last year, we had one Big Brew site that had three television stations covering their all day event that included brewing, raffles, a children's coloring contest and more. Many Big Brew sites got the media to cover their story before the event and had potential new brewers showing up to participate and learn. There was one site that brewed 415 gallons of homebrew in 24 hours, another that brewed 2.8 gallons. Many sites had only one participating brewer, while one site had 460. People were brewing in their homes, at homebrew shops, brew-on-premises, brewpubs and in other public areas and events. This year, we already have many of those sites participating along with some international sites. The sky's the limit. We're giving you the ammunition to promote homebrewing in your area. There's no fee.* I encourage all of you to participate. For more information, go to the Big Brew '99 webpage at http://www.beertown.org/bigbrew99 or contact me directly. PS - We are trying to have at least one Big Brew '99 site in each state. Please check the webpage to see if your state or area is represented. Thanks.

Add false bottom, make it or buy, or easymasher tm, drill and forget welding, this may cause slight dripping, but a couple of drops per min is a lot cheaper than welding fittings in. And you can change setup if desired. If propane fired, get 3 new ring burners, extra tank to prevent stoppages, connecting to a two tier system. Add Pump and use hose with quick disconnects if possible. Use brass where every possible, forget SS and save your money. Get a good CF chiller (or make your own) I still don't know about my B-in_law, even this might be pushing it. === Used Ball-Lock Soda Kegs for sale.
