---------------------------------------------------------------------- Date: Fri, 2 Dec 94 11:33:55 PST From: raines at radonc.ucla.edu (Maribeth_Raines) Subject: O2 saturation, foaming, etc. Jeremy writes that the saturation level of wort which I said was 8 ppm "is only for adding oxygen with air. The levels can be made much higher with pure O2 gas, which is used by many commercial breweries." This was part of a debate a few months back. George presented very convincing data showing that the SATURATION LEVEL is 8 ppm. Saturation is saturation no matter what concentration of oxygen you're putting in. The only difference is that rate at which the saturation level is reached. And of course you would expect saturation to occur much faster with pure oxygen rather that with air. Also George's experiments were done with injected oxygen not air. I was wondering how long it would take before Bob posted regarding the foaming issue. This is a problem with all aeration systems, unless you do what Bob did and devise an in line system. My experience has been that with extract beers I tend to get minimal foaming even in a big bodied extract. I have yet to have a batch foam over. BTW I use a 6.5 gallon plastic bucket for my primary.(Yes PLASTIC but that's another story) so I have a fair amount of head space. My all grain beers foam all over the place. There are a few things that help. First I run a splitter off of my aerator so that I aerate 2-3 fermenters at once this in essence reduces the pressure. You can also restrict the line by putting a clamp on it. Finally I have beer working on identifying some food grade antifoaming agents to counteract this problem. This would be especially helpful for aerating starters. If anyone has a line on such chemicals let me know. The porosity of the carbonating stone also affects foaming. It turns out that the porosity needed for an aquarium pump is pretty high so the bubbles formed are large and tend to foam as much as dissolve. An aquarium pump will not push air through the optimal size porosity for dissolving gasses in liquid (2 microns). Those of you who use pure oxygen or bottled air (alot of breweries use bottled air for safety reasons) could use a smaller porosity carbonating stone which would also help. Where to get them is a different story. E-mail me. If there is enough interest I will arrange for some to be made. Oh yes, with regard to protein denaturation. I have no idea why they're denaturing but my guess renaturation would be minimal. The fried egg example is a good one. Cheers! Maribeth Raines raines at radonc.ucla.edu Return to table of contents

OK, I can't help but chime in. My daughter (now 4.5) has *never* liked coffee, beer, or soda. I have given her tastes of everything and she has no desire for it. My sone (now 2.5) has *always* liked coffee, beer, and soda. He wants to drink as much of it as I will let him (I generally allow him small sips of such things, though he doesn't need caffeine or alcohol in his small body). So, you can't generalize these things, as there are variations. And they can change over time. I can't trust my son unguarded--he will grab the can or bottle or glass and drink as much as he can. I would definitely consider this in any design. John DeCarlo, MITRE Corporation, McLean, VA--My views are my own Fidonet: 1:109/131 Internet: jdecarlo at mitre.org Return to table of contents
Date: Fri, 2 Dec 94 11:55:47 "PST From: michael j dix <mdix at dcssc.sj.hp.com> Subject: Flavor Wheels I ran across the beer flavor wheel a dozen years ago, and I now have two wine flavor wheels as well. It's a little hard for me to explain how it works but... Basically it is a scheme for standardizing and categorizing the descriptive words people use when they taste something. This technique makes tasting objective instead of subjective, and can be used for data analysis. Once people are trained on the flavor wheel, they have a common language. For example, weiss beer is described as being clovey. I might call it something different. The flavor wheel provides a reference point. Moreover, clovyness falls under the the general category of phenolic tastes , which is under chemical tastes, etc. (if I remember the details right.) Similarly with wine. I tasted one white wine and said "new tire." My neighbor said "burnt match." We were detecting the same thing: sulfury taste. The wheel is also used for comparison tastings: A is more malty, hoppy, grapefruity than B, but less flowery than C, etc. (These are probably not the correct words.) So by ranking various constituents, you can provide a road map of the beer. This is probably a good starting point for developing clone beers, because you need to describe your target before you can try to hit it.

Date: Fri, 02 Dec 1994 14:51:24 EST From: WNXP21A at prodigy.com (MR PETER E MISIASZEK) Subject: FERMENTAP I purchased two Fermentaps about a month ago and have put them through their paces. I have to say, I like them alot. What the Fermentap consists of is a rack to hold an inverted carboy, and a cap assembly that accomodates a vent tube and a spigot. The end result is a good approximation of a cylindroconical fermenter. The spigot allows yeast harvesting as well as draw-off of spent hops and break. By connecting two in series, CO2 from the primary can be vented into the secondary to purge it, and the beer can be racked to the secondary "closed-system" without siphoning. The parts seem to be top quality, and the service has been good. There is a special price if you buy two, and if your primary is a carboy, I'd recommend two based on my experience. I'm not affiliated in any way with Fermentap. Pete Misiaszek, brewing BayBeer in Newport RI. Return to table of contents

This is my first strong lager. I plan to save 1 qt of wort for krausen priming. I'm using Wyeast Munich Yeast in the ferment. Should I use a different yeast to start the krausen or should I harvest from the primary and save it somehow? Any advice on this or decoction mashing would be very welcome via email to RWaterfall at aol.com. BTW after reading aeration thread here, I plan to aerate with old aquarium pump and a cotton plug.

Laatsch <LAATSCH at kbs.msu.edu>" <LAATSCH at kbs.msu.edu> Subject: Lindeman Kriek Lambic Hello fellow brewers, Warning: this may be more appropriately posted in rec.food.drinks.beer or something, but I don't have usenet access, so sue me. I recently had my first opportunity to taste an "authentic" Belgian Kriek Lambic. It's made by a company called Lindeman's and comes in a miniature green champagne bottle with both a cap AND a cork. It was intensely red/cherry colored with a very effervescent pink head. I expected a rather sour flavor, as I have been indoctrinated by Papazian that Lambics are very sour. Instead, the aroma was very reminiscient of cough syrup and the flavor was VERY sweet---in fact, not sour at all. I must say the style barely resembled a beer, i.e. it had virtually no beer "character" and was more like a cherry beer/champagne. It was certainly drinkable, but just not what I was expecting based on what I've read. My question to the more seasoned imbibers: Is this typical of the style or did I just purchase an expensive dud? Thanks for your patience. BREW ON! Bones - ----------------------- tim laatsch laatsch at kbs.msu.edu k'zoo, mi Return to table of contents

Summary: Expires: Sender: Followup-To: Distribution: world Organization: Netcom Online Communications Services (408-241-9760 login: guest) Keywords: Just now brewing my second ever brew -- a Sparrow Hawk Porter from NCJHB. It fermented like crazy for the first three days or so and then tapered off significantly. Yesterday (day 5) I racked to a glass secondary and the SG read 1.030. In the book, Charlie says to shoot for 1.012-1.020, and since I haven't seen any activity since racking, I'm wondering if 1.030 is as low as I can expect it to go. As per the instructions, I'm using a lager yeast (dry European lager yeast, can't remember the name) at ale temps in the style of Anchor Porter. OG was 1.058 (adjusted for temp). When should I be worried about stuck fermentation and think about repitching? Is this likely to start bubbling a little again soon? Love to hear from anyone who has tried this beer or style. Thanks in advance for the help. -John (through Mario at sprmario at netcom.com) BTW, tasted during the racking and it was spectacular! Would recommend this recipe for any porter fans who haven't tried it yet.. Return to table of contents

I really wouldn't think it >would work too well to add a large amount of fermentables to it. Why not? No, really, why not? You don't need to add more oxygen because there is enough yeast and they have (hopefully) had their fill of oxygen from the first "feeding." I don't see any reason that you could not add a half gallon of 1.100 wort made with some additional hops. Just boil up some wort with some hops in it, chill, don't aerate and add it to the fermenter. If you can add fermentables like fruit in the secondary, then why not malt extract? ************** Jeremy writes: >their number. I did this earlier this year and it turned out great except >for a better than average mash yield resulting in an OG of 1.077! Adding >some Brettanomyces smoothed out the esteriness. Hmmm... odd. There appears to be a lot of difference in Brettanomyces yeasts, if indeed the Brett you added reduced fruitiness. Two of the three Brett yeasts (I'm pretty sure they are Bretts from their behavior -- I do not have the time to test them otherwise) that I have been working with produce lots of esters. I'm not sure about the third one since I've only tasted it in a fruit pLambik I made. I'm very pleased with their ester production (and so far, disappointed with their horseyness, etc.), but this seems contrary to Jeremy's experience with the Brett he used. Could it have been something other than the Brett you added that smoothed-out the esteriness, like age or oxygen? ************ Bob writes: >What's the deal with the flavor wheel? The flavour wheel is a circular chart of beer flavours originated by someone in the American Society of Brewing Chemists (ASBC). It's printed on the plastic tasting "glasses" that are distributed by the AHA. It's handy, I suppose, if you taste a particular flavour in a beer, but can't recall what to call it. However, the wheel only lists a small percentage of the flavours that you can perceive in a beer (relative to the words Jackson or Protz use) so it's usefulness may be rather limited. Al.

"The Outlaw"), I like your attitude.... brewing beer in AL is STILL illegal.... hmmmm I wonder if there's anything we can do to help you guys out down there?? Any ideas? My BBS Network did help to legalize brewpubs in Texas recently.... Whenever _I_ refer to the amount of starter that is pitched, I am referring to a volume of ACTIVELY FERMENTING WORT, preferably at high kraesen (i.e. when it has the biggest head on it!). This is obviously a much greater volume than the same amount of yeast dregs all by their lonesome... I like to pitch at least 1 quart of actively fermenting wort at high kraesen per 5 gallon batch. Now, I dont always have that luxury, and do not hesitate to just pitch a fully-swelled Wyeast pack when I have not had the time to make a proper starter. Hope that helps.

This is my first post and as others have clearly stated, the HBD is a wonderful resource -- and so are the neat pages on the web (just got mosaic running -- graphics! cool!) Cats Meow 3 has a great look and of course is full of recipes - Kudos to all of those involved. That said, now....beer talk - -------------------- In HBD 1594 Kevin asked about how to avoid the carmel clumping of DME in hot water. Try dissolving the DME cold water -- then raise the temperature. (BTW this works with cornstarch or flour in gravys and sauces too) - -------------------- I'm going to make an oatmeal stout with a recipe from CM3 which calls for a few ingredients that are new to me, I'd like to ask for a bit of advice: 1) recipe calls for 2/3 stick brewers licorice. The stick I bought is about 4 inches long, about 3/4" dia. Do I really want to use 2/3 of this? I've heard horror stories about some seriously bad beers made with too much of this stuff. 2) recipe calls for "steel cut oats" - the local homebrew shop had flaked oats, not cut. I did find the right oats at a health food shop for a mere $ 0.77 / lb. This stuff looks like couscous...is it? - --------------------- Lastly, Charlie P.'s Homebrewers Companion talks of a new federal regulation which changed the way municipalities chlorinate drinking water - he simply recommends filtering water as the chlorine will no longer dissipate by simply filling a carboy and allowing it to sit out. Can anyone expan on this? I had noticed a strange off taste in about 3 batches, which got stronger after about 3 weeks in the keg, eventually ruining the batch. This taste had the "bandaid" like flavour, I believe Chlorophenol (sp)? Since installing a simple countertop filter, this taste is gone! (I also switched to idophor but I don't think poorly rinsed bleach was the problem) Cheers -=pkbwp=- - ------------------------------------------------------------------------ Kurt B. Wurm, P.L.S.

One bottle was not as well carbonated as the others and it got me thinking whether our proceedure of mixing in the boiled corn sugar could be improved. Currently we just dump the boiled sugar into a 7 gallon food grade plastic bucket and siphon the uncarbonated beer into the bucket. After, we siphon the beer into bottles etc. Has anyone come up with a better way to ensure the carbonation sugar gets spread throughout the beer? I'm looking into the 5liter mini-kegs for the future, but I would still like to be able to bottle my beer and make sure it's just as carbonated as the rest of the batch.

According to recent tests by George Fix (his original post@tached), there is "no way" that levels of O2 detrimental to yeast can be obtained no matter how much O2 is injected/bubbled into the wort. Actually, when you look at his chart, the highest saturation he obtained is 8.1 in a somewhat low gravity wort (these were the saturation limit using "lengthy" O2 feeds"). There has been a lot of discussion about this recently, so I hope Dr. Fix doesn't mind me reposting this. Also, if there has been some new data added to this (like at the Denver meeting), I would be interested in hearing it. >From HBD 1446: >Date: Thu, 9 Jun 94 09:37:32 -0500 >From: gjfix at utamat.uta.edu (George J Fix) >Subject: Wort Aeration >I am currently working on a new book (Principles of Brewing Science II. >Practical Considerations) which I hope to get to the publisher by December. >Wort aeration is one subject that I wanted to treat in detail.

The words 'slow' and 'unreliable' came up and they found the new stainless steel Glatt Mill to be superior in production and quality. Not sure this is even worth responding to as it is ludicrous at face value. The Glatt has about 1/4 the throughput of the MM and a notorious history for catastrophic failure. Furthermore, to call something with a stainless steel hopper, "stainless" is less than totally honest. Finally, I find it interesting that most of the public responses to my posting completely missed the point and attack me while all the private mail was very supportive of my position. The posting was about a dishonest or at least mis-guided method of testing the integrity and ruggedness of a roller mill. I only brought up the plastic gear failure as proof of the pudding. The fact that Glatt finally listened to the screams of their irate customers is only an incidental detail. More importantly, the catastrophic failures in the Glatt have been the result of bad design and ignoring the problem for over a year says more about the companies concerned than one unhappy MM customer. Can't help but wonder how long he is going to insist that plastic bearings are a good design. js Return to table of contents

I don't know what your municipality collects for recycling, but I don't think they'd take caps...don't forget the liner (and thelabel if you used one). Those would seem to make them unacceptable for recycling. 2) RE: Batch numbers v. styles, labels v. marker. Now a batch number alone could be easily legible with marker alone (as long as it's not a dark coloured cap), but I use labels with both batch number and a style abbreviation--and colour coded labels for quick identification. My batch numbers incorporate the year and a sequential number, with an abbreviation for the style. For example, 94-15 with IPA under it could be the 15th batch of 1994 (for reference to the log) and it's an IPA (for quick identification of the style). Furthermore, the coloured cap label makes it easy to keep them sorted into six packs and/or cases as the supplies dwindle and I consolidate cases to save space. Including both pieces of information tells me more than just it's an IPA, but it tells me _which_ IPA.

Date: Sat, 3 Dec 1994 18:19:03 -0600 (CST) From: Teddy Winstead <winstead at cs.tulane.edu> Subject: Clear Beer/Sabco Brew Kettles/Keg Conversion FAQ/Unix Brewing Software First of all, I purchased a Sabco Brew kettle from The Home Brewery this summer, and while I'm fairly happy with the product, I'm not 100% satisfied yet. A brief review -- the product is a reconditioned half-barrel keg with a coupling for draining, and coupling for a thermometer, and supports for the false bottom welded into it. It comes with a stainless steel lid. The false bottom is just a piece of stainless steel window screen with a rubber "frame" encircling it. This frame allows the false bottom to butt right up to the wall of the keg and make a snug fit.... Or so I thought. The first time I brewed with it (a "Porter Light" -- recipe of my own creation), I has TONS of problems clarifying my wort by recirculating it. No matter how much I recirculated, I still had pretty substantially sized chunks of grain and husk in my wort! So I called the Home Brewery, and they told me that a number of incorrectly-sized false bottoms had been shipped. They promptly got me a new one, but this beer was really astringent from all of that grain going into the boiler. My next brew, a Bock (recipe from Richman's excellent book) had some clarifying problems as well. I recirculated until I was ready to drop, but I still had some grains in the wort. This beer tastes fine, but the wort never really got clear. So, most recently, I made a batch of pale ale (95% Hugh Baird Pale malt, 5% CaraMunich). This was an experiment, and I put an 8" piece of perforated SS sheet metal under the window-screen false bottom, and under the uptake for the drain. Here's a graphic -- | | | | | | | | | | | | |--------------<------------- False bottom of window screen |\ /| | \ ------------ <------- Drain w/ elbow on inside | ======== | ^--------------Bottom of keg w/ 8" SS False Bottom above OK. This wort had no grain chunks, but it still hasn't really gotten quite clear. But what happened was interesting -- I got TONS of slimy, trub material on top of the second false bottom, along with some grains. This would indicate to me that LOTS of stuff isn't being caught by the first (window screen) false bottom. So, the product obviously isn't working as it should. The grain for all these batches was crushed in a MaltMill from my local HB shop which is DIRECTLY motorized (i.e. there's a power drill connected directly to the crank shaft for the rollers). SO -- What's my trouble? Could it be my HB shop's grain mill isn't crushing the malt "right"? Has anyone else out there used this product and had substandard results? I'm thinking that I'll give the Home Brewery another call to find out what could be wrong. I'd appreciate someone giving me some feedback on this product. - ----- On another note, what other factors influence getting really clear beer after fermentation? Water treatment? If so, why? Boil times? Again, why? I know that water treatment has some effect on finished beer clarity, but I've never seen an explanation of exactly why. - ----- The Half Barrel Keg Conversion FAQ has been finished.

Date: Sun, 4 Dec 1994 16:29:15 EST From: "pratte" <PRATTE at GG.csc.peachnet.edu> Subject: Newbie question In yesterday's post, Patrick Humphrey asks (after being scared to death by discussion on the HBD) about possible HSA problems with his first batch. He added 100 F wort to 80 F water and wonders whether he has ruined his beer. I would have to say that if his beer is ruined, this is not the cause. I usually only cool my wort to somewhere between 100 and 120 F before adding it to 50-60 F water and have yet to have a bad batch (spruce beer to the contrary). He also asks about a high hydrometer reading (1.080 with only 7.6 lbs of malt). Before making a final SG reading, I would calibrate my hydrometer. To do this, take distilled water and cool it to 60 F. Whatever the reading is, you can use this as an approximate correction factor for readings in the future. However, if it is off by the .020-.030 that you apparently have, I would return it for a new one. Several months back, a couple of people wrote in to say what a disgusting experience with spruce beer they had. Others told them to be patient and that after a year, the beer would taste great. Well, mine has been in the bottle for 1 year 2 months now, and it is still disgusting (no, I didn't use too much. I even used less than Papazian suggest in his book). HOWEVER, I have found a great use for it. I use it as a marinade for pork. I especially like to add 1 bottle to a pork roast with a couple of cloves of garlic and several fresh sprigs of rosemary (bake for 1-1.5 hours depending on size). The smell is incredible. While I'm wasting BW, a note of local interest. A new brewpub is opening in Hickory, NC. Now, all spouses that get dragged there for furniture buys (for the furniture impaired, Hickory is a mecca for furniture with every other store in town being a furniture store of some sort) can go hang out in the brewpub and while away the day trying their beer. They are still waiting to get get the official go ahead from the BATF (10 weeks), but they plan to have 5 different styles of beer on tap: a stout, a wheat, 2 ales, and 1 lager-style ale. Until they get their license, you can still enjoy the food and the 48 premium beers (not Budmilloors) and 2 ciders that they have. The place is called the Olde Hickory Brewery, Jim Walker is the brewmaster, and it is located on Highway 70 in Hickory. John - -------------------------- Dr. John M.

Date: 04 Dec 94 18:32:24 EST From: Don Rudolph <76076.612 at compuserve.com> Subject: Wyeast 2278 Czech Pils Joe McCarthy asks about Wyeast 2278 (Czech Pils) in HBD#1595. I have brewed three batches with this strain, two Bohemian Pilsners and one Vienna. The only comments worth making in comparing this to the other Wyeast lager strains is that it does produce a LOT of sulfur during fermentation. It does condition out over time, and it is worth the wait. This yeast produces a wonderfully round and smooth maltiness and I would recommend it for any malt-accented lager. I've heard said that these sulfur-ish compounds, when at perception thresholds, will accentuate malt aromas and flavors. Is this why?

Date: Mon, 5 Dec 1994 02:39:04 GMT From: cetnier at nn.apc.org Subject: reducing yeast layer in bottles In a few days I'm going to try an experiment to reduce the amount of yeast I get in the bottom of my bottles. I'd like some comments, if anybody has done it before. Normally I use a food-grade covered plastic bucket with airlock for my primary and rack the beer to a glass carboy after 4-7 days. When fermentation has stopped, I siphon the brew back to the bucket, to get it away from all that yeast sediment, add priming sugar, and bottle from there. My siphon has a standard little cap on the sucking end, so I leave almost all the yeast in the carboy, but a little gets stirred up in the process. I have noticed that the bottles have most of the yeast in the bottom they are going to get by after a day or two. I interpret this to mean that suspended yeast has settled out, not that the yeast has become so active that it reproduced and created that much yeast. This suggests the following experiment with the batch of Rocky Racoon's Crystal Honey Lager (Papazian's recipe) that has recently stopped fermenting and is sitting, crystal clear, in my brewery: Instead of transferring it back to the bucket and bottling right away, I will transfer it to another carboy, where it will be able to sit in peace a few days. When the yeast I stirred up in the first transfer has settled, then I will siphon it to the bucket and bottle. I see two possible risks here: 1) Too much O2. Adding a transfer increases the possibilities for O2 to come into contact with the wort. This problem is particularly acute with this batch. I did this experiment earlier on this batch, when the bubbles seen in the carboy were so few that I thought fermentation was almost over. The result of the transfer was a renewed vigorous fermentation. (Good thing I didn't prime and bottle it!) So this batch has already had one more racking that I normally do. Thought I would add ascorbic acid this next time, the first time I've used it. 2) All the yeast can settle out, leaving none left for the bottle conditioning, and I have a sweet (from the priming sugar), flat beer. The manager of one homebrewing shop in nearby Stockholm told me that some of his customers say this has happened to them. I have a hard time believing that. I don't think you can get rid of yeast that easily and am betting that the carbonation will develop a little more slowly but become just as strong as usual. My questions to anyone who has tried this are: a) Does this method work to reduce yeast in the bottle? b) What do you say about the risks? I hope this isn't anything that has come up recently on HBD; I'm just subscribing now after going through a bunch of back issues from the first half of the year. TIA!

Date: Sun, 04 Dec 1994 22:58:08 -0500 (EST) From: BRETTNKAY at delphi.com Subject: Kitchen Aid Grain Mill I have in my kitchen already one of those Kitchen Aid mixers which has this power take off shaft on the front to which you can attach various tools like cheese shredder, etc. Ive seen in a catalog a grain mill attachment which if adjustable enough would make a very nice electric grain mill for around $100. Presumably since these are not hot sellers, Ive never seen one in person at a store. Has anyone used or even seen these mills and if so how suitable are they for cracking grains. I would like to make the jump to all grain but right now Im using my burr coffee grinder to grind specialty grains and its just not going to cut it for larger amounts.

I hope this suggestion is not too heretical, but my pregnant wife has felt constrained as of late in her consumption of my beer and I wondered if anyone had any ideas for how to make a (palatable) non-alcoholic brew. I'd be especially interested in hearing from anyone who has tried it, but theoretical suggestions would also be most welcome. (I hope, too, that this is not an old thread since I am new to this particular discussion group.) Thanks in advance, Don Ulin Bloomington, Indiana Return to table of contents
Date: Sun, 04 Dec 1994 10:44:59 -0500 (EST) From: "Software Happens." <johnm at giant.IntraNet.com> Subject: Hello-thanks / All grain question / Beer Party Suggestion I've been lurking here for what seems like forever. I've read alot of the homebrew books (Papazian, Miller, Burch, Eckhardt, Zymurgy) but have still received a wonderful education from the HBD. I thank you all. I've been brewing extracts for about three years and recently made the jump to all grain. I found the exeprience to be fairly simple, highly rewarding, but a tad time consuming. I plan to start future all grain brews early in the morning to minimize the time spent in the kitchen when I could be with the kids! A few notes on my process. I mashed on on the stove top with my five gallon stainless steel pot. I attempted to follow millers instruction by placing my pot into a 140 F oven once I had reached the specified temperature. Unfortunately, the lowest my dial has is WARM, which frequent checking of the kettle revealed to be too high as I was always overshooting my target temperature. For my next brew(a step infusioned porter from Papazian), I modified the process. I set the oven on warm for five mionutes and then turned it off. I brought my mash to the specified temperature on the burner and then placed the covered kettle in the oven. I was almost right on for each temperature step, maybe a degree off here or there off but nothing like the 5 - 10 degrees experieinced on my first brew. I used the Phil's lauter system and found it quite easy to work with. The one thing I forgot for the porter recipe was the half pound of black patent malt. I just wnet ahead without it so basically I have a brown porter in my primary which I beleive is a little on the high side (SG 1.060) for the style. Could I steep or minmash the 1/2 lb of the missing ingredient in a quart or so of water and then add to the secondary prior to racking? Beer party suggestion: I've been throwing a party for my megaswilling friends for the past three years. Each year I brew up 3 batches of beer for the party. Usually I try to keep the styles in season, this summer I threw a barbecue with a hombrewed WIT, a Honey lager, and German PILS. I send out a humorous newsletter/invitations with a description and a little history of the beer styles. In the invitation, I also request that individuals contribute to the beer tasting by seeking out commercial examples of the styles to bring to the party. I also give extra credit (usually beer glasses or 22 oz. bottles of local microbrewed beers) as an incentive for anyone finding, say, an Australian Wheat beer or a Dusseldorf Altbier. This little tactic helps them get a little more beer education since they have to ask questions at the liquor store (many of them bring the invitation with them). It also helps replace my homebrew until I can brew again since theer are always some (not many) leftover microbrewed and imported beers. The party has been a huge success and my friends are getting a little more educated about beer styles, brewing, and beer tasting every year. Return to table of contents

I always thaought that aluminum pots gave a metalic taste to the beer, after all TNCJOHB says not to use them. What does the collective knowledge of HBD have to say about this? E-mail or public posts would be fine and I'll summarize if I recive many replies.
