I'd like to invite everyone out tomorrow Saturday for our grand opening with Michael Jackson. Michael will conduct a tasting of Texas beers at 3. What was intended to be a rather small event has grown beyond expectations. There are an incredible 30 Texas breweries attending the opening and serving free refreshments throughout the day. This represents about 3/4 of all Texas breweries and is easily the largest gathering of Texas brewers ever. Collectively I'm sure there will be over 100 different Texas brewed beers available. I leased 45 acres behind the warehouse and now have plenty of parking and another large tent and in fact have tickets still available for the tasting ($15). All homebrewers are welcome to come to the grand opening whether they attend the Jackson tasting or not. Michael will be available all day to chat and sign books, particularly his latest Ultimate Beer. Map is on our web page http://www.stpats.com Best regards Lynne O'Connor St. Patrick's of Texas Brewers Supply http://www.stpats.com stpats at bga.com 512-989-9727 512-989-8982 facsimile Return to table of contents

The sankey valve could be removed | from the 12" disk and then welded to the lid of a corny keg | for those with the sankey tap systems.I did not pursue this | project but thought I would pass it on for those that might | run with the idea. Another Idea I have seen (Larry's Brewing Supply, Renton WA) is that they welded several 1" washers around the edge, sticking halfway over the edge, and used the dip tube, and welded it to the top of the sankey valve bent up about 30 degrees from horizontal. (after plugging the valve shut) and using it as the Lid for your new boiling pot.

Date: Wed, 12 May 1999 18:03:44 -0500 From: John.Wilkinson at aud.alcatel.com (John Wilkinson) Subject: RE: Furry Projectiles In The Night Having been loafing on vacation in the Carolinas for a week or so I just this week got back hard at work catching up on HBD. I try to squeeze in writing a little code now and then as a break. Anyway, I read Phil Yates and Dr. Pivo (aka D. Quayle) discussing whirling cats overhead by the tail. I caught a possum (opossum to you yankees) in the trash in my garage and decided to try a variation of the experiment. However, the possum was too heavy and the skinny tail too slippery so I never reached my rpm goal. Fortunately the garage door was open and the slippage took place in the right part of the swing. I didn't hear any glass breaking in the neighborhood so I guess he sailed into the woods from whence he came. My cat made it quite clear that the experiment was to go no further so I guess I will have to wait until I develop a stronger grip or catch a lighter possum before I retry the experiment. Man, science is fun! John Wilkinson - Grapevine, Texas Return to table of contents
Date: Wed, 12 May 1999 22:00:26 CSTCDT From: "Anthony & Julie Brown" <brown32 at web1.ecol.net> Subject: wheat yeast strains I have been using the wyeast 3068 wheat yeast for my traditional wheat beers but they seem to come out close but not just right. I am wondering if I should use a different type of yeast to obtain the results I am looking for. I am trying to duplicate a Haaker Pshorr Weiss type flavor(pardon my spelling). If anyone has any recipes (extract) or opinions on which wheat strain to use it would be greatly appreciated.... Tony B. Return to table of contents
Date: Thu, 13 May 1999 14:31:08 +0200 From: "Dr. Pivo" <irv at wireworks.se> Subject: Krauzening A "Bayer" Krauzened Weiss. Imagine that - having the inherent regional brewing style baked into the brewer's name. You sure that that is not just a "phoney" name that you are "hiding" behind, Mr. BAYER. I'm not sure I trust you. You kind of remind me of that "squirrel" guy. You sure you're not the same person? Are you entirely sure that you're not me? Actually, Mark Bayer asked quite a few very relevant questions about krausening a weiss beer.... none of which I can answer. Specially not regarding a Weiss as I don't brew them. I do do quite a bit if krausening, and it always along side of the same beer that is treated in some other manner (artificially carbonated, gyle primed, or "naturally" lagered), so do have a bit of a feel for what they do. The Krauzen yeast you introduce, will dominate the style. If it was going to be a diacetyl producer or reducer, it will do it regardless of whether it is left in its original batch, or taken out as a krauzen.... but not necessarily under the same conditions. I don't think to my knowledge, I've ever had a krauzened batch that has been a heavy diacetyl producer, unless I "trick the yeast", such as cold shocking them, and then letting them work a few more weeks back at temperature. This can be done VERY long into the lagering cycle (months), as the yeast seem to behave as though in a state of suspended animation. It will also attenuate the same as the "mother" batch. Probably most important, is that a krauzened batch is so uniquely different than other fermenting methods, that it has a "style" all its own, and hard to guess what is appropriate compared to the same batch "non krauzened". That is, it makes such a complex flavour, that whether you want it drier or sweeter etc. would be your own personal choice. I tend towards "sweeter" because part of the "krauzened" taste is enhanced bitterness. There are I think three dominant sources of that (by my taste buds, not from any literature sources) 1) is a much more pronounced "hop flavour". The flavouring and aroma hops tend to stand out more, more sharply advertise their "style" and more importantly MUCH longer. 2) almost invarioubly, there is a slight "snap bean" flavour, that adds to the "young, green" taste. 3) there is always a "fresh yeast" taste. My guess is that all of these are effects of the incredible reductive power of the yeast when it gets dumped in. I think most importantly.... > it's a good > experiment to compare with past non-krausened batches. my intent in > krausening is simply to try it and see what the flavor impact is. Yep. That's the ticket. It will undoubtedly surprise you, teach you where you want to go with it (if you indeed do), and I would only make sure you've got some "non krauzened" alongside, to taste and really compare the fine points. Preferably taste at several different ages, since krauzening is sort of like capturing a small "window" of maturity, and extending it over long times. Regarding temperatures they're your choice. Yes, I would drop from primary temperatures, but your secondary (at least mine) are already cooler, so you've already made the step. I like going to the secondary temp for about two weeks (4C, 5C?) (this is called a "carbonating" step, but I expect there is much more going on there), and then dropping it to as cool and as long as my patience allows. Small batches you might want to take a bit slowly there, big barrels, just roll them into the cold room, sit on your hands, and wait for the magic. I've called krauzening a "fountain of youth" but maybe a Czech brew master put it better (direct quote, without grammatical or syntax change): "Krauzen is like young woman". I think this particularly sexist comment, delivered with a leer, was referring to the firmness of the flesh of youth, and how all the training programs and make-up in the world cannot recapture that when someone gets to my sagging jowled age. Dr. Pivo > i'm considering writing an article for bt or zymurgy. potential topic: > _the massive flavor impact of hydroxyapatite in beijing breweries_. I think most of the hydroxyapatite in Beijing has come from my teeth, after riding my bicycle into a gutter after "a long night out"... I'd start looking there, just next to Dongzhemen, in the ditch beside the public "squatters". Return to table of contents
Date: Thu, 13 May 1999 08:36:43 -0400 From: "Jeff Beinhaur" <beinhaur at email.msn.com> Subject: SureScreens Al K. brought up my problem with "cloggage". From my original post I received the following from Jeff McNally: There are 2 things you need to do to avoid this problem: > >1. Wait about 5 minutes after moving the kettle before you open the >drain valve. > >2. Open the drain valve slowly and only enough to get the flow going. >After the flow is going for a minute or two, slowly open the valve up >all the way. > > I'm assuming that you are using only whole hops (or plugs). Pellets >will plug up the drain no matter what you do. My response to Jeff was, "call me skeptical". Surprisingly enough when I brewed again this past weekend I followed Jeff's advice and it worked flawlessly. Thanks again Jeff. By the way I used fresh whole hops and hop plugs. I must also mention that I neglected to add any amount of Irish Moss (must have been the effects from the Troeg's Pale Ale, right Jeff Woods?). I mention this because another person had mentioned that this can cause clogging. Jeff Beinhaur, Camp Hill, PA Home of the Yellow Breeches Brewery Return to table of contents

A few people in this HBD have not been very honest about who they really are. Mr Burley, don't squirm there in your seat. No wonder you have ducked off for a bit of a holiday! And Dr Pivo, just how long did you think you could get away with this. Oh you are so very cunning indeed! Arguing so bitterly between yourselves. And all of us watching in awe. So many wicked distractions, secret squirrels, name calling, scenes behind a barn! Even Eric Fouch was struggling to keep up! And now we learn the truth. A modern day Dr Jekyl and Mr Hyde hiding right here in our very own HBD! This is absolutely monstrous!!! Phil and Jill Yates. (now I'm getting a bit suspect about these two as well)!

Date: Thu, 13 May 1999 08:45:46 -0400 From: "Roat, Todd (ROATTW)" <ROATTW at UCMAIL.UC.EDU> Subject: Hop Bags - What's to Lose ? I always use hop bags in my 15.5 gal brewpot for the simple reason of "ease of cleanup". However, in a theoretical attempt to not compromise the hop utilization (just in case this is true ;^) I put the hops in a large grain bag (a grain bag that will hold about 8 lbs.). My theory is that this gets the hops as close as possible to being "free-floating" while still keeping them contained for easy cleanup? Seems a reasonable assumption, no? Todd Todd W.

Date: Thu, 13 May 99 07:51:12 -0400 From: Dave Humes <humesdg1 at earthlink.net> Subject: R.E. "Dave Humes Assumes" OK Phil, as much as I disagree on having a public discussion within the HBD on a topic having nothing to do with beer, you leave me no choice. Your post touched a very raw nerve, as last summer my wife and I spent a week staying up all night nursing one of our cats back to health because of a similar incident as you described. We didn't see it happen or know who did it, only that the vet said that it looked like someone intentionally cut her tail. Fortunately, it was not cut all the way through. So it was possible to reattach it and now she is fine. But, we spent a lot of hours wondering who would do such a thing and why. There's a lot of crazy people out there who really do mutilate animals. So, on reading your post, it was not difficult to imagine that someone could actually do what you described and my reaction was admittedly based on anger and it came out with a rather nasty tone as you say. Now you may think that I'm making this all up just to get some sympathy votes. Wrong. I'll be glad to take some digital photos of the veterinary emergency room bills and send you the files if you like. Now, as to your remarks about having a public discourse on this subject. I make a concious choice in responding to posts whether private email or a post to the digest is appropriate. In this case, it just simply had nothing to do with beer. So, in my opinion, it does not belong on the digest. Note, I am breaking my own rule by responding to you here. Contrary to your statement, I do not consider myself the self-appointed "Chairman" of the HBD. Your post was the only one I have ever responded to stating that I thought the material was inappropriate for the digest. Apart from the digest's moderator who only steps in in the most extreme cases, we (everyone participating on the digest) are the real moderators of the list. And we do it by telling other people what we like or dislike, using either the digest or private email depending on which is appropriate. I simply don't want to see the digest turned into the likes of the Jenny Jones show on topics that have nothing to do with beer. I am glad to hear you and the neighbor's cat are bonding, and by the way I only wear a tie for funerals and weddings. - --Dave - -- - ----------------------------------------------------------- Dave Humes <humesdg1 at earthlink.net> Dave Humes - ----------------------------------------------------------- Return to table of contents

Date: Thu, 13 May 1999 09:01:36 -0500 From: Nathan Kanous <nlkanous at pharmacy.wisc.edu> Subject: Decoction Profiles Mark says: I have a brewhouse report from the Stroh's brewery in Winston-Salem, NC. They take 10 minutes in the transfer so as not to destroy any enzymes by dumping a lot of hot, boiling mash in all at one time. I have also read in Kunze that the addition of the decocted mash should be done slowly to avoid damaging the enzymes. So I figure between 5 and 10 minutes. This is what I have read in Kunze and Noonan. I say: Ten minutes for Stroh's brewery to transfer so as not to destroy enzymes? Let's think, how many hundreds / thousands of pounds of decoction are they moving? I'll be it's a lot. Could it be done faster? Maybe only with a dump truck? Is the reason that they do it slow a limitation of the equipment (no dump truck or fancy "dumpable" decoction tun) or a necessity (a pump can only pump so fast)? Just a thought...no offense intended. nathan in madison, wi PS you also need to "hold after the decoction" to allow for saccharification to occur...that was the real reason for decoction, to get the mash to the temperature for a rest Return to table of contents
Date: Thu, 13 May 1999 10:09:06 -0400 From: Joe Rolfe <rolfe at sky.sky.com> Subject: o2 in microbrews Al K said... <snip - some stuff on Chicago Brewing> >up by various other breweries, but their beer suffered from >oxidation rather than sanitation problems. This crap (below not above)/QD has no bearing on homebrewing unless you are going pro or are a pro wannabe... Not surprising. It is easier to produce clean beer than to produce low o2 beer in a bottle. Chicago (if memory serves) had a flash pastuerizing set up ahead of the filler. These work great if used properly. But the item that bugged me was the filler was real close to the door and they ran the filler with the door wide open...Got lucky I guess. Most micros that use a short tube, (Meyer or similar filler) will have problems if they dont take some precautions to pre-evacuate the bottle with co2 or other suitable gas. I dont know how many micros have know with these fillers that have gone out of business by not taking care of this "issue". Yeah I'm sure some have had other problems also. Many have told me "cap on foam" is enough. I dont know about that - you would have to do a packaged air test. I doubt it would be a real good number and I doubt the o2 cap is going to pull that much air out. At that point it is probably to late anyway - the damage has been done. All this rarely matters if the beer is sold thru within a month - but then most micros do that (sell thru) anyway - right?. My advice you just spent a sh*tl load of money on the brewhouse, tanks and support items. Then your going to cheap out by $50K or so diff between a good filler and a bad one. Dont do it even if it looks like a great deal... Like I said useless info for a homebrewer....sorry to waste the bandwidth for the majority.... Joe Return to table of contents
Date: Thu, 13 May 1999 08:11:08 -0500 From: "Brett A. Spivy" <baspivy at softdisk.com> Subject: Labeling method summary . . . Hello all, I trust this finds you well. As usual, I got an overwhelming response to my labeling query. I thought I would post a summary, since everyone was so gracious and I have recently become aware that there are more Newbie Lurkers subscribed to the forum than there are ChemHead Multi-posters with 3000 gallons and twenty years of HB under their belt (no offense should be taken here, I like the Chemistry stuff, I just don't understand it - YET!). More than a half dozen bottlers have only bottled and have purchased pre-glued, pre-printed labels and based on their past experiences recommended that I do the same. This idea, I don't like, but thank-you for the input. About a dozen, some who kegged but bottled "gift" beer, said stick with the glue stick, but use a water soluble generic instead of Crayola TM and use a LOT less glue. Apparently, I should be able to label almost three cases of beer from one stick if applied properly. The general consensus of "properly" was "just around the edges and a small X in the center should get the job done and maintain my "easy to float off " constraint. This group could not resist encouraging a speedy movement to kegging. I like this idea, but still think there must be an easier, more consistent method. The Beerslayer uses various methods. For just a few wine bottles, clear laminate sheets over computer printed labels gets it done. For more than that, 50-50 white glue and water brushed evenly over the back, dry to tacky, then position carefully 'cause it not movin'. The short dry prevents wrinkling of the label due to saturation at the time of placement, but it does negate the ability to move it around any. Once again encouragement towards kegging dominated the conversation. This method makes the most sense to me because of the nature of water souluble "school glue" and its dirt cheap cost ($ 1.90 for a quart). This last method came from four different posters and one personal phone call (a lawyer too, wish I could get MY lawyer to pick-up a phone, I wonder if that call was bilabial). This is not only the most creative and cost effective method, it appeals to my basic nature because it seems somewhat rustic in basis. Milk! Yep, good old milk. Whole, 2%, 1%, Skim, whatever. nobody knows why but it sticks tight as a drum while dry and then floats off in a ten minute soak of warm water (one said he mixed 100 ppm chlorine bleach and sanitized while de-labeling). "Don't soak the thing, just wet the back and stick it on - works like a charm." was the most convincing comment. I really like the idea of this method and if it works, will go this direction. I still have a week or more before bottling time for my first batch (just racked to secondary 2:30 this morning), so I am going to 'sperment with the milk thing tonight and see how it goes. Thanx to all who responded. Brett A. Spivy Postscript: I received maybe thirty more emails after I wrote this, but before it had been sent out of my out basket. They pretty much followed the same spread and advice with three notable exceptions. The vast majority of bottlers that have done it more than two years prefer the milk method. One person suggested 3M spraymount which I have already experimented with (in the marketing activities I complete for my company, I use all seven 3M spray adhesives extensively). This stuff really holds, and it can be just peeled off in most dry mount situations, but when the bottle sweats or is put in a cooler this adhesive has some VERY unfavorable properties for fast east removal -- its out. That brings up most everyones problem with the milk method - put your bottle in a cooler (without a baggie around it I mean) and the label floats right off. Then I got a very interesting post about a product called UHU gluestic. Goes on purple, dries clear (this is also a property of the Crayola TM GlueStick I mentioned earlier. Here's a snip for you: UHU brand glue sticks hold up well in cold water, and the labels will not fall off if the bottle sweats. VERY HOT water will cause the label to drop off in a few seconds. When you factor in that at the Office Max this product is half the price (by volume) of the Crayola TM, I think I'm going to do my first batch with half milk and half UHU and see what I like best. Thanx agin to all. Return to table of contents

I knew that if I read HBD long enough that the conversation would sooner or later turn to something that I know way too much about, and I could step up and lecture. Well, here it is! I've worked with both M. jannaschii and Azotobacter. The Methanococcus was dead at the time, since I had it at room temperature, atmospheric pressure and an oxygen atmosphere. It won't survive an autoclave, because it's an obligate anaerobe -- i.e. oxygen kills it. (Nothing that is pathogenic in humans survives autoclaving, as far as I know.) Even if you did manage to get around the problem of temperature, pressure and oxygen (and, yes, your beer may not be oxidized, but it still has enough dissolved oxygen to kill obligate anaerobes), you still have to get around the fact that what Methanococcus really likes to do is make methane, which will not, to my knowledge, make a creamy head, although you would get to light your beer on fire, which would be a cool bar trick. Azotobacter grows at room temperature in oxygen. It's a soil bacterium, and, yes, it fixes nitrogen. The problem with this plan is that nitrogen fixation doesn't make N2, it eliminates it. Nitrogen fixation is really important because all organisms need nitrogen to make amino acids for proteins, but they can't use atmospheric nitrogen, so it has to be reduced to ammonia (fixed) by the few bacteria that can do so. Yeast can't do it, pediococcus can't, hops can't. Even botulism spores and fruit flies and cats can't fix nitrogen :) Here's my equation for the year: N2 + H2 ---> 2NH + H2 ---> 2NH2 + H2 ---> 2NH3 each step catalyzed by an enzyme in an electron transport chain. So, by using Azotobacter, you take any nitrogen you have and turn it into ammonia. This might be detectable as an off flavor, and won't make a nice creamy head either. Plus, I know from experience that aerobic Azotobacter cultures smell like a combination of rotting wood and baby vomit. Even those in the HBD collective who believe that style guidelines stifle creativity would be hard pressed to sit back, relax and drink an Azotobacter culture. Sorry about the length of this, and for taking a joke too seriously. It's not often I get to talk about my specialty :) Jesse - -- Jesse Stricker jds19 at acpub.duke.edu Return to table of contents
Date: Thu, 13 May 1999 07:42:40 -0700 From: Jack Schmidling <arf at mc.net> Subject: SureScreen(tm) BrewInfo <brewinfo at xnet.com> " Temporarily, I fixed the problem by getting a long (30-inch?) stainless steel spoon and scraping the screens. An hour later, I had gotten 95% of the wort out, pitched and went to bed... As I stated in my response, it is my experience that any attempt to scrape the screen during the process will only aggrivate the clog. Keep in mind that as you scrape, you not only (hopefully) unclog the screen but several other unwanted situations are created. First of all you may actually force some of the trub into the screen and clog what is not already clogged. Secondly, you create an area of suspended material in the vicinity of the strainer which immediately gets sucked into it and much of it clogs the screen. My suggestion for dealing with a clog is to allow the trub to settle after scraping to set the filter bed, just as one does when starting. Don't let it run while scraping. This also implies that not letting the wort settle long enough is also the cause of the clog in the first place. I have not had a clog in years but I also use a pump which probably mitigates the problem somewhat. I also recommend blowing on the end of the hose rather than scraping as a minimal disturbance technique. Al will of course have to use microbe free laboratory compressed air instead of the easy way but no one ever accused him of doing things the easy way. I wonder if it has anything to do with his oft repeated comment that he has not had time to make beer lately. js p.s. Any word on the family Al? Won't be able to jazz you anymore. You will have three much better excuses. jjs - -- Visit our web site: http://user.mc.net/arf ASTROPHOTO OF THE WEEK: http://user.mc.net/arf/weekly.htm Return to table of contents

How much of a 10-12 lb grain bill >would one put in...2 lbs? This seems to be a natural for dark ales. It gives a richness and body - almost oiliness in large amounts. It's a nice additional ingredient to have available. It is available from North Country Malt Supply, PO Box 665, Rouses Point, NY 12979, (518)297-2604. (std. disclaimer) I made a 1.050 brown ale/strong mild and used 10%. For my Domesday Ale, a 1.096, unhopped, uncarbonated recreation of a midieval ale, I used 50% - home malt stout uses 22%. Wadsworth's Oat Malt Ale ( a "wine red hue") uses 11% with another 6% unmalted pinhead oats. I'm slowly going through the book looking for other beers made with it. You will probably have a hazier wort/beer that will take time to clear. >From a note I got from James Fawcett of Fawcett & Sons, Maltsters http://www.fawcett-maltsters.co.uk/welcom.htm , who are the only producers of this that I know: "3) Oat malt laboratory worts are normally slightly hazy rather than clear. Oats are not normally low in protein and are quite difficult to modify from a protein viewpoint, which could well explain this. Our current stock gives values of 11.8 % total protein with an index of modification of 27.8%. 4) As far as mash schedules are concerned we would suggest you ensure temperatures are between 63 degrees C and 68 degrees C during mashing in with a one hour minimum stand after mashing in a grist composed of 50% oat malt and 50% lager malt. 5) You should aim at a liquor/grist ratio of between 2.5:1and 3:1. 6) Oat malt needs very close mill settings to achieve an acceptable grist. For normal malts our standard mill setting is 62 thou top and 58 thou bottom- for oat malt we drastically reduce these settings to 48 thou top and 42 thou bottom. Certainly a point to watch to produce an optimal grist for mashing." Jeff -=-=-=-=- Jeff Renner in Ann Arbor, Michigan USA, c/o nerenner at umich.edu "One never knows, do one?"

Date: Thu, 13 May 1999 18:18:24 +0200 From: "Dr. Pivo" <irv at wireworks.se> Subject: Beerhound in Beijing > "Anyhow I've got a collected catalogue of 38 beers drinkable within > Beijing, if anybodies interested." > > I would be very interested, I have several friends in that part of the > world. I might get there myself in the near future. I never thought anyone would take me seriously, only mentioned it to demonstrate my own lunacy, but perhaps it is of "general interest". Remember that these notes are 11 years old now: GENERAL NOTES: RESTAURANTS: You may find that you bump into a beer in a restaurant, that you never find in a shop. Some just come that way. Anything it China that actually "works", usually does so by way of "the back door". There is a word for friend (pengyou), where I never did quite learn the distinction between where the concept "friend" ended, and "business contact" started. If you have a friend, who has a friend in the restaurant business, you can get some interesting stuff by the "back door". Beijing White Lable "Banquet" is an example of one of these rarities. SHOPS: Delivery is erratic. If you find something nice someplace, go back and buy all you can, it might not be there again for a month or two. The rule here is "stockpile". PARTIES: Refrigerator space is at a premium in Beijing. If you're planning a "whoop-it-up" ("hey folks, wan'na come taste my 'collection' on Saturday?") look for the Rickshaw drivers (they're not called that, but OK) that hang out near where they sell soft drinks on the street. They keep the bottles melted into little holes in a big slab of ice. The Rickshaw guys deliver the ice. They'll deliver a HUGE slab right to your door for next to nothing. They are not so used to dealing with foreigners, and consequently friendly and honest in my experience. BICYCLES: The favoured mode of transport in Beijing, which is really "the world's largest collection of villages". If you turn down a little alley, you'll suddenly find yourself "peddleing through a dirt road in a village", with the old men sitting out under the tree on the "village square". You just can't get there by car. The city is flat, the Chinese bikes are of an entirely different ergonomic design, where your legs are "out front" peddling, instead of directly under like ours, and suit well for just peddleing slow all day (with the occasional beer and food pause). You should seek out three features on your bike: 1) Older ones are as good as new. Chinese quality control is not a "big thing" so if you buy a new one, half of it will fall off before you've gone down the street.... they just put the nuts on, they don't tighten them. "Feng hua" (phoenix) and "flying pidgeon" are two sturdy brands. 2) Every Chinese bike has a bell the size of a small bathisphere. It should ring loud, shrilly, and long. Your bell should be heard two city blocks away (the average Beijing city block is about 8 kilometers long), and would be, if everyone else wasn't ringing their bells at the same time. Ring your bell often and proudly. You don't want to "sneak up" on anyone, as it can be a major traffic hazard when they suddernly jerk their head to stare at the "wai guo" passing them. Your bell is your sign of respect in traffic. If in doubt that your bell is the biggest on the street, mount two. 2) All Chinese bikes have "fold out" wire baskets on the back. Buy the biggest size you can find. The big guys will fit 8 large bottles a side, and are invaluable if you finally find "an odd sought after brand" across town. BEERS: BEERS TO LOOK FOR: Beijing "white label": 3.5-4 vol. light with round fine fruity taste, and an unusually clear bitterness that lingers. Beijing "black label" 15P. preferred by many foreigners. A light taste with good bitterness. A bit "ricey" and too much alcohol for my tastes. Five Star: 11P. Light, fresh. Fresh aroma. very nice. Yangang beer 12P. nice light lager taste. a bit "honey sweet". Quanchi beer: slight roasted flavour - very mild and with a gentle caramel sweetness. Well carbonated. Xing Can 11P. A lighter pilsner with unusual initial flavour, sweet aroma, and a somewhat metallic bitterness at the end that fades into a quite comfortable bitterness. The roasted background is somewhat overshadowed by this. GuoduPijiu 10.5P fresh roasted taste, bit on the sweet side. Coffee ice cream aroma. Oriental Beer 12P same brewery (Guoyingdongfang) as Guodu. Nice light and fruity taste. Aolei Beer 12P Mild with caramel undertone. Good. Feng Run Pijiu 11P. soft but quite full in flavour. Light fine bitterness. Inconsistant carbonation between bottles. QingQuan Pijiu 12P, 13P Good, fruity, rich. ShandongLiaoChen 11P Burst of "Pommac" or"apple soda". light after taste. YuQuanShan Pijiu 10P fruity, a little sweet. "fresh" taste. A little "Bayer" like in flavour, but a little bit strong "rice" taste. Qingshiba Pijiu 12P. Full flavour. inconsistant carbonation. Fine "flat" malt flavour. Huanghe Pijiu 12P, and "87" 15P. somewhat musty, light sweetness. Something pilsner reminiscent here. Zhu Jiang Beer 12P. light lager. Honey sweet and "round". A bit "alcohol" dominant. Liu Quan Pijiu 12P. of the "roasted" quality, but light taste and "apple seed" bitterness in after taste. That's probably enough.... there's plenty more. BEERS TO "WATCH OUT" FOR: Fenxing Pijiu: flat thin. Shachen Pijiu: Sour two weeks after bottleing. Yu Die 12P: pukey, watery. Beijing "light" beer: meaningless.XinLu Pijiu: watery, low carbonation, sulphur "yeast stress" stink. Now aren't you sorry you asked? Dr. Pivo (Pijiu Dai Fu) Return to table of contents

I have successfuly used it to stop wild yeast infections in kegs and also to protect low alcohol and low bittered beers from infections. I haven't detected any flavor changes although I have heard that is possible. If I was going to sweeten a beer with honey, I would try to rack it off the sedimented yeast as much as possible, maybe even a coarse filtering, before adding the honey and potasium sorbate to minimize its work.
