Bill wisely included the recipes *and* fermentation temperatures, but my possible source for the "Bandaid (tm)" flavor/smell is, alas, unrelated to these two pieces of information. The off flavor/smell is due to phenolics. According to the Zymurgy troubleshooting issue, Troubleshooting chart, it can be caused by: Chlorinated (tap) water, wild yeast, bacteria, oversparging of mash, boiling grains, cleaning compound residue, plastic hoses and gaskets, and defective bottlecap linings. I ommitted a few causes listed in the Troubleshooting Chart from the troubleshooting issue (Vol 10, #4, Special issue 1987) because I disagree with them (so there!) and have included a few which I think are less likely to cause the particular flavor with which you are concerned (bottlecap linings, oversparging and boiling grains, specifically) but this is just intuition. I have not personally had this problem, so I'm afraid my suggestions are based upon reading, combined with intuition, but for what it's worth, I think that the most likely sources are: 1. chlorinated sanitizing solution residue (solution: rinse better) and 2. chlorinated water (solution: boil all the water you are using in the beer).

Jack sez: >I used to see the owner of the local brew shop standing outside his shop watching cars go by, every time I passed and I just assumed the hobby was as unpopular as it ever. Poor guy. Don't know what he's doing wrong. My friend Jeff owns the Modern Brewer here in Cambridge, Ma. He's been open a little over a year and he's doing really good business right now, even with the bad economy. My observation is that the growth in interest in micro-brewed beers and homebrewing is very strong. Of course these are my observations here in Beantown (and a few other areas I've traveled to, your mileage may vary..) > My target was and still is all those people out there that do not even know that one can make drinkable beer at home. Let's face it, most of them like Bud. My personal experience is that few people go from Bud to homebrew. Typically they "discover" microbrews or imports and their tastes change before they make the leap to brewing themselves. Again your mileage may vary.. (hey let's introduce a new acronym for this... YMMV) > From: Jay Hersh <hersh at expo.lcs.mit.edu> > > >The presence of phenolics which the clove-like..... > > BINGO! > > The second most recent batch (just about drinking age now) has precisely that > taste and aroma.

Jack I'm not sure what to make of this reply, I think you may have misunderstood. The cloviness comes from the YEAST not the wheat malt..., Red Star Ale, which you said you used to use until recently if I read this right, (which I stopped using long ago after a friend got the banana beer that tasted more like bananas than bananas do..) is reputed to produce clove flavors under certain fermentation conditions (I don't know what these are supposed to be). - JaH - ------------------------------------------------------------------------ Hopfen und Malz, Gott erhalts Return to table of contents

What to do if you don't have a convenient dark storage place for your fermenting beer? Take a standard brown grocery bag and cut a hole in the center of the bottom. Make this hole slightly larger than the neck of your carboy. Invert the bag and place it over your five gallon carboy, it's a perfect fit. I'm sure if you put the carboy in direct sunlight in Southern California (;-) you could still damage the beer, but under "normal" circumstances you should be OK. If you want added protection, use two bags. Cheers, CR Return to table of contents
Date: Tue Nov 05 10:36:09 1991 From: larryba at microsoft.com Subject: Hey, Jackie baby - chill out. Not everyone on the HBD is your nemesis. Either you are pulling peoples cords just to see what kind of boing they make or you are being a bit too defensive. Anyway, my recipe for oxidized doctored beer was a attempt in helping you understand the oxidized flavor/aroma in beer so you would be better equiped to detect it in your homebrew beer. I don't necessarily think that you will detect oxidation in your "mishandled" beer. Why? Because it is my belief that if you have active yeast in your beer, oxidation may not be an issue. Beer that is primed and bottled has live yeast in it. Live yeast is very reductive (?) and chews up the oxygen + reduces the oxidized components. I have heard that damaged beer can be revived by adding fresh wort, yeast and letting it re-ferment. I think that is what happens for many home brews: they are harsh at first (green?) and then as they age they mellow out. I think it is the yeast doing it's magic. Comment, Dave Rose, George Fix? Anyway, I lager in the refer (ales and lagers) until the beer is fairly clear. I then keg and artifically carbonate. There is little or no yeast activity at this point. If I am not careful about O2 infiltration I get a distinct "stale" taste/smell to my beers (sample of 2 out of 17 so far). I have never had that happen with bottled homebrew or kegs I primed. Typically, my beers are very drinkable/clean as soon as I carbonate them. Aging helps, but not nearly as much as it helped my old, sloppy, bottled extract beers of long ago. The point is that you may well be right that oxidation is not an issue for homebrews if the air infiltration is not grotesque and there is a secondary ferment in the bottle. It probably depends upon the gestalt of your brewing setup. What works for you might not work in all cases. Knowing the defects and what the underlying causese are can help you determine what is important for your setup (or videos!) As for skunk beer in Miller bottles: I trust you were kidding me... The beer has been doctored, not the glass! Return to table of contents
Date: 5 Nov 91 14:27:00 EST From: Joel (J.N.) Avery <JAVERY at BNR.CA> Subject: priming with honey I posted an article in the last week of September about priming with honey when someone else was asking. Anyways, for a 5 US gallon batch, I use about 3 or 3.5 oz of liquid honey, but I tend to prefer a lighter carbonated beer when compared to my homebrewing buddies. You are better off brewing a flatter beer the first time, and then adjusting the amount of honey you use. Make sure you boil the honey with some water to kill off any live cultures that might exist in the honey. It also makes the priming "sugar" mix better with the beer. I just pour the boiled honey and water into my priming pail shortly after starting my siphon from the carboy. Never had a problem. javery at bnr.ca Return to table of contents
Date: Tue, 5 Nov 91 12:34:07 -0700 From: Loren Carter <lcarter at claven.idbsu.edu> Subject: doctored beer A while back someone(I think it was Chris Shenton) asked about doctoring beer in order to train judges etc. Our club has done this several times in the past with good results. In addition to skunky(light struck) and oxidized beers mentioned in HBD we have used the following: Metalic taste FeSO4 sweet taste sugar acidic lactic acid or vinegar alcoholic vodka medicine taste listerine phenolic phenol butterscotch diacetyl(use butter or buterscotch flavoring) ester flavor bannana oil In place of the listerine and the phenol last time we used oil of cloves. This seemed to work as well or better than the listerine and phenol and is easier to get than the phenol for most people. Hope this helps.

I'm the nervous type.", I thought, "geez, he _is_ the nervous type". Then I realized that I do the very same thing, almost subconsciously. Of course, I consider myself perfectly NORMal. To Pat Patterson: Here's some results from the honey-priming experiment I did: I didn't want to reply until I had some results. I used 1/2 cup of clover honey from the grocery store, and it worked great. I just boiled it in a pint or two of water and primed as usual. A week later I've got plenty of carbonation and no off-flavors. I wouldn't use more than 1/2 cup. To everyone: Let's get off the old flames and on to new ones, and have some fun.

This absolutely does not lead to contamination .... I'd be quite surprised Dave if you use unplugged sterile pipettes to dispense your yeast. The fibrous plug found in the top of culturing pipettes is tightly packed and adsorbant enough to stop potential microbial contamination carried by microscopic particles dispelled with each humid breath. > apparently, breath is sterile. If you've ever done animal cell culture or bacterial culture using media much richer than liquid malt or malt/agar you'd know, from painful experience, that breath is not sterile. > In short, breathing into the carboy is not a problem, as long as you don't > drool into it or something. I'd tend to agree with this without any contradiction to my above comments. The media conditions must be hospitable to potential contaminants and acidic hopped wort may not be well received by the types of microbes in your breath. Furthermore, no homebrewer's wort is "sterile" but this poses no problem if enough healthy yeast are pitched to outgrow other life forms. I'm still extra careful anyways.

Both alcohol and fusels along with some amines are the cause. The liver, that wonderful detoxification centre, requires the B-complex to provide cofactors for various detox pathways. The high demand for B-vitamins results more in a shortage than an imbalance. I've had better luck taking time-released B-complex prior to indulgence rather than after but either way will help. As mentioned above, plenty of water is still the best treatment since it rehydrates the spinal fluids and helps to flush ones system of toxins. Taking a teaspoon of fructose rich honey along with water also provides the liver with a good energy source.

You'd end .....much other good sense about coriander seeds deleted... Correct me if I'm wrong, but are you sure that _seeds_ were specified in the recipe? Coriander seeds have a _very different_ flavor from the leaves, which are yet again different from the root. Three completely different spices from one incredibly groovy plant. I can't remember the recipe that was given, but the leaf flavor is the most common one in most forms of cooking (aka chinese parsley). Off the top of my head, I would think I'd prefer the leaf flavor (common in Mexican and Indian cooking) in beer to the seeds. But then, maybe I'm completely off base. Steve T.

Date: Tue, 5 Nov 1991 16:45 EDT From: BAUGHMANKR at CONRAD.APPSTATE.EDU Subject: Counterflow chillers Greetings friends and neighbors: I've been quiet enough lately. Guess I should put my two cents in on the chiller discussion. I'm not trying to be testy. Just want to make sure things remain balanced. And please, let's don't ever say "m_m__y" again. It's a stupid word and besides, my Mom wouldn't even think of making beer! >While on the subject, I'd like to add a couple more reasons that I feel the >immersion chiller is better than the counterflow type: >1. cleaning is easier on an immersion chiller and you can see how clean >the surface that contacts the sweet wort is, > >2. sanitation is easier - all you have to do is dunk it in the boiling >wort before turning on the cooling water (you may also be able to sanitize >a counterflow similarly, but intuatively, I suspect that by the time >the hot wort is at the exit end of the chiller, even with the cooling >water off, it has dropped below 180F which does little to sanitize the >tubing, and Actually I find sanitation and cleaning of the counterflow chiller to be just as easy and effective as sanitizing the immersion type. Drain the chiller body of cooling water after a round of brewing and siphon boiling hot water through the empty chiller until the boiling hot water exits the bottom. Store it dry. Before the next brewing session, I generally siphon some of my just- prepared, ever-present solution of 1 Tbsp. clorox to 1 gallon of water sterilant solution through the copper and let it sit for 20-30 minutes. That's not enough to corrode the copper, BTW. Then just to make EXTRA sure that everything's sterile, I start my chilling session with the chiller dry, so that immediately after the short clorox soak, the copper comes into contact with boiling hot wort. If boiling hot wort is good enough to sterilize the outside of immersion chillers, it's good enough to sterilize the inside of counterflow chillers, too, unless I'm missing something. :-) >3. I, personally, would not want to start a siphon (with my mouth (besides >the sanitation risk) or by other means (turkey baster, etc.)) on a 170+ F >liquid! Me neither. That's why I (a) either let the clorox water that's inside the chiller start the siphon or (b) insert a small 2" piece of 3/8" tubing into the end of the siphon hose and suck on it. When the wort approaches the mouth, pinch the hose shut, remove the tubing, and direct the flow to the fermenter. I do like the fact that the counterflow chiller chills the wort very quickly. One drop of wort goes from 212 degreess to 70 degrees in about 6 seconds and then comes into immediate contact with the yeast. Not much time for a bacterial infection there. Whichever chiller you decide to use -- and in the end it is a matter of personal choice -- I do agree that it's the time-saving features of the chiller that I enjoy the most. But I happily accept the associated reduced risk of contamination and better cold-break. While on the subject of time-saving, again, I might as well make the point that the counterflow chiller saves more time especially if you make a habit of siphoning into the fermenter anyway. With the counterflow, you can start siphoning into the fermenter immediately. With the immersion, you have to wait 20 or 30 minutes for the wort to chill before you can begin the siphon. A nit-picking point, I admit. But, hey, at least I'm not arguing about whether oxidation is a real phenomenon. The first 3 or 4 batches of beer that I kegged were deep-sixed because I couldn't tell whether it was beer or some sort of weird sherry. As for initiating homebrewers into our hobby, I emphasize the following: Use good ingredients, good recipes, and good clean equipment. Make up a 4 or 5 gallon batch of sterilant and soak everything that touches the cooled beer in it for 20 or 30 minutes. Keep racking to a minimum. When it's time to rack, treat your beer like your lover. Be gentle with her. Don't abuse her. Don't slap her around or dump her into bed, er, I mean, the carboy. Ease her into it. Talk nice to her. Let her know you care. See! That wasn't difficult was it? Homebrewing is easy. Hey, Darryl, you radical! You've gone from "Eunuchs" to Microsoft and MSDOS!!! My how the mighty have fallen!

Last night I brewed up some beer and when I had everything in the carboy the temperature was 85 degrees. Since Papazian sais the pitching temperature should be about 70 - 75 degrees I waited till the next morning, but I had trouble relaxing. It seems to me, in retrospect, that it would have been ok at that temperature.

I could swear this was done at UC Davis. However, I can't find a reference, but some of my Beer & Brewing books are on loan.

I would like to suggest that for competitions, please use nice clean unscratched 12 oz. standard longnecks. It is ok to use 10 to 14 oz. brown or green bottles (please do spectrophotometer readings to test for light blockage between 423-587 nanometers ;-) but it is much better to use the standard bottles, it makes life easier for everyone. I have directed an AHA state competition and a judged a coupla AHA nationals and its makes life easier if the bottles are all uniform. I talked to Dave Welker (AHA national director) about this and he had to disqualify some good brews because they were out of spec re: the bottles, and I know it really bothered him. Read Zymurgy Vol. 14, no. 1 (spring 1991) article on shipping beer to competitions ("Fragile - This Side Up" pg. 27 - Russ Wigglesworth). If you send your prettiest bottles it helps! RE: Hangovers Alcohol gets converted (by alcohol dehydrogenase) to acetaldehyde, which is sickening, it builds up because alcohol is converted to acetaldehyde faster than acetaldehyde is broken down. The acetaldehyde probably causes the majority of problems (along with fusel oils) it causes direct cell damage and is a free radical. L-Cystine scavenges the free radicals off of the acetaldehyde and in single blind experiments (unpublished observations) it seems to alleviate the 'edge' of a hangover when given with lots of water and b vitamin complex prior to processing the majority of the alcohol consumed.

The Saffron Superkeg, a 6+ US gallon plastic keg with an (optional?) cap for CO2 cylinders and a pressure relief valve, is distributed in the US by Crosby & Baker. Your homebrew store should be able to order it from them. It happens that I kegged my first batch in one last night, so I can't give any practical results yet. However, be warned, as I was, that such kegs are designed for British "real ale" levels of carbonation, i.e., very low. The Superkeg is designed for at most 15 psi, which is the nominal level at which the relief valve opens. Since I'm drinking my last batch (a porter) by keeping the bottles at room temperature, and letting the beer sit a few minutes after opening to allow it go flat (it tastes best to me like that), I don't expect a problem.

Being that I use this particular yeast a lot and have had no problems with it I had my homebrew shop check into the report and see if they could find anything out from the manufacturer. They finally got a change to call Wyeast regarding the reports about an infected batch of #1007. According to Wyeast they have not had any reports of an infected batch of yeast.

Most likely it's bacteria, not mold. I had the same thing once and had it checked at my wife's bio lab, and it was bacteria, 'though they couldn't say what kind without more (ie. $$$) tests. All new plastic cured it. Thomas M. got "possible food poisoning" from his infected wort. Yes, it's possible, but more likely you just picked up a flu bug. There's a bug out now (I'm just over it, knock on wood), that mimics food poisoning pretty well, with stomach pains that are *unbelievable*. In the past I got what I thought was food poisoning after eating at a restaurant, went to the emergency room, and found 5 other people with the same symptoms, who hadn't eaten at the restaurant. The culprit? Flu. The hospital folk said "stomach distress" cases are much more likely to be the flu than food poisoning. So it could have been FP, but my experience says it's not likely, for whatever that's worth. Russ G. OPAL/ESP UNH Return to table of contents

I'm the nervous type. Well, that *is* pretty nervous ;-). I guess I've not made myself clear, and I'm sorry about that. From the point of view of the brewer, it makes sense to protect their beer as well as is necessary with their methods. For homebrewers, this may not require the use of dark brown bottles, since they (often) know better. For a commercial brewer bottle color may not matter at all since ignorant retailers (by far the majority) can hurt them regardless. But, from the point of view of the taster/judge, bottle color makes no difference, since a clear bottle may contain perfectly fine beer, and the darkest brown bottle may contain skunk juice. I take as my starting point that commercial beer will be skunky if I don't know how it was treated, and that homebrew will not (since there is a "real" person behind it who would do their best not to hurt it). I also wanted to make the point, since I've heard about judges who automatically assume that beer in a green bottle is of lower quality than brown (and more than once), that that is an outrageous and unwarranted assumption.

Has anybody out there used or heard of using lactose? Let me try to ferment two worts with one pitch, as it were. I've tried to duplicate Xingu, but reduce some of the roast barley bite. I think I've succeeded, though I haven't done a side by side comparison. I believe that Xingu is what's known in the UK as a milk stout, as I believe that lactose is used to add body and to very slightly sweeten the flavor. Here's "Josh's Better Xingu." Again, it's close to Xingu, but I think its better: To make 5 gallons: 6.6 lbs M&F Dark Extract 1 lb Crystal Malt 1/2 lb Chocolate Malt 1/4 lb Black Patent Malt 1/4 lb Roast Barley 1/2 lb Lactose 2 oz Northern Brewer (Boiling only. No finishing hops.) Gypsum 3/4 cup Dextrose (priming) Wyeast 1028 Crack and steep specialty grains at 150 F for about an hour in 1/2 gal water. Sparge with 1.5 gallons of 165 F water. Add the extract and Gypsum. When boiling, add the hops. Boil for one hour, add the lactose to the boil for the last 15 minutes.

Jack, most of us who use "blow-off" methodologies do so using a 5 gallon carboy as the primary fermentation vessel. The benefits are closed fermentation and removal of crap with reduced risk of infection. >BTW, I like skimming. It makes me feel like I am contributing something to >the process. You'd mentioned earlier (in rec.crafts.brewing) that you've been losing two out of ten batches to contamination. It may be possible that your open fermentation and/or skim technique may be contributing to this. I used to use a 7.5 gallon plastic tub, and skim, and had similar problems, no matter how careful I was with sanitation. I switched to a closed fermentation technique some years ago and haven't had an infection since. I truly believe this was due to airborne stuff in my house, as the same procedures and ingredients would produce great beer one time and weed killer the next, due to infection. Check out Papazian's book. The first section, supposedly for beginners, will show you the carboy/blowoff methodology and has a great discussion on using plastic primary fermenters at its end. - ----------------------------------------------------------------- Josh Grosse jdg00 at amail.amdahl.com Amdahl Corp. 313-358-4440 Southfield, Michigan Return to table of contents
Date: 6 Nov 1991 10:55 EST From: dab at pyuxe.cc.bellcore.com (dave ballard) Subject: my $.02 on light damage Hey now- I just wanted to add my $.02 on light damage and skunkiness since I had a recent problem concerning just that. I decided (after some prompting) to enter my first batch, a pale ale, in the NYCHG competition in NYC on 11/2. I was pretty psyched 'cause the stuff came out really good and has been improving with age. The age at judging time was about 5 weeks after bottling. Anyway, I check out the judges sheets after the contest and their only real complaint was skunkiness. Now, I had a bottle of the stuff on the night of 11/1 and it was anything but skunky. I cracked open a left-over bottle at the competition and sure enough it smelled/tasted like Pepe le Peu's bathwater! All I can figure out is this- when I dropped my three bottles off at Greg Zaccardi's (who did a great job organizing by the way), we were standing around bs-ing for like 10 or 15 minutes and the bottled were in the sun. The were brown Whitbred bottles, really thick. I guess this doesn't add much to the conversation other than more proof that exposure of even just 10 or 15 minutes is enough to do some extensive damage... later dab ========================================================================= dave ballard | Reach out your hand if your cup be empty, dab at pyuxe.cc.bellcore.com | if your cup is full may it be again, Return to table of contents

Well he no longer lives here and guess what is still sitting beside the house? Thats right a keg that is half full of the most oxidized beer imaginable.

It didn't seem all that important. Yow! It's Very Important! You can get good results without aerating (although you didn't this time), but if you want your yeast to really take off, aeration makes all the difference. Here's what I do: - Rack into carboy (or bucket or whatever) - Seal it up - Shake it and roll it and slosh it for two or three minutes - Open it up and pitch the yeast - Reseal with airlock - Relax >When there was no >trace of fermentation by last night, I decided to rack it into my >other carboy, since about three inches of spoogy sediment had already >accumulated. I also thought that racking would aerate it a little. A little, but probably not much. Try shaking the hell out of it. This should stir up the sediment and aerate it at the same time. If that doesn't help, jeez I don't know...maybe your yeast died somewhere between the packet and the beer. >My wort is still okay, right? Probably... >I can go out and get some more yeast and pitch again, right? Absolutely. It sounds like that's probably the best bet.

Date: Tue, 5 Nov 91 14:22:46 PST From: pierce at chips.com (John Pierce) Subject: UV light As several people here have made some generalizations about UV light and glass, I thought I'd throw my 2 bits in. UV filters for cameras DO work. Ordinary glass only blocks SHORT wave UV, not the near visible LONG wave that photographic film is sensitive to. Try this... With a decent 35mm SLR, and color film (especially slide) shoot some distant scenic pictures of say mountains on a reasonably clear day. Shoot a few more with a standard (SKY) UV filter. Shoot some more with a HAZE filter. The pictures shot with a naked lens will show a definate blue haze in the air that the two UV filters will reduce significantly. Try shooting said distant scene through a piece of medium gray colored plastic. Now shoot it through a pair of decent sunglasses. (I've never tried this last, actually, let me know how it comes out ;-). Now, I am not a photo-chemist, so I don't know what wavelengths beer is photo-sensitive too. But I'll bet the answer is more complex then you might think....
