On the Sam Smith W.W. bottles they have dates for example:1993-1994, this is sometimes mistaken for the winter of 1995 (which actually starts in Dec. of 94)sometimes distributors will try to get rid of their overstock from the previous year before they sell the new stuff, and they get away with it because people see the 1994 date and think it's from this year,THIS IS NOT TRUE!!!The new bottles say 1995 on them!!!! I work in a pub and a distibutor tried to do this to me and luckily I tasted one before selling it and YUK, it tasted like a tin (aluminum)can!!! The bottom line here is that if you buy beer from a store (or pub) and it doesn't taste right, then it probably isn't,SEND IT BACK!!!!!if a store gives you a hard time get the address of the distributor or the brewer and write or call them, more than likely they will respond!If you can't get the address or phone # email me.......I CAN......

My Vienna was lagering in the refrigerator out there, with hopes that a truly fine beer, I soon could share. The Airstat was useless, 32F couldn't be set, so I turned the Fridge to Low, to see what I would get. On Monday it was 40, On Tuesday lower yet, On Wednesday morning I tweaked it, seemed like a good bet. Later that day when I walked out to the shed, my nose gave me pause, I was filled with dread. In through the door I hurried and dashed, when I tripped on the stoop and fell with a crash. Everything looked ordinary, well what do you know, but just in case, I opened the fridge slow. When what to my wondering eyes should appear, My carboy had FROZE, I had made Ice beer! My first thought was tragic, I was worried a bit, I sat there and pondered, then muttered, "Aw Sh**!" More rapid than eagles, my curses they came, and I gestured and shouted and called the fridge bad names. "You Basturd! How could you! You are surely to blame! You're worthless, You're scrap metal, not worth the electric bills I'm paying! To the end of the driveway, with one little call, They will haul you away, haul away, haul away all!" Unlike dry leaves that before the hurricane fly, when brewers meet with an obstacle, they'll give it another try. So back to the house, wondering what to do, five gallons of frozen beer, a frozen airlock too. And then in a twinkling, I felt like a doof, the carboy wasn't broken, the beer would probably pull through. I returned to the shed, after hurrying around gathering cleaning supplies, towels, whatever could be found. I changed my clothes, having come home from work, if I were to stain them, my wife would go berzerk. I was loaded with paper towels, I knew just what to do, I had Iodophor-ed water and a heating pad too. The carboy, how it twinkled! I knew to be wary, the bottom wasn't frozen but the ice on top was scary! That bastard refridge, it had laid me low, trying to kill my beer under a layer of snow. I cleaned off the top and washed off the sides, picked up a block of ice and threw it outside. I couldn't find the airlock, it was under a shelf, and I laughed when I saw it, in spite of myself. The work of a half hour out there in the shed, soon gave me to know, I had nothing to dread. The heating pad was working, the ice fell back in, I re-sanitized the airlock, I knew where it had been. Not an Eisbock, but a Vienna I chose, it was the end of the crisis of the lager that froze. I sprang to my feet, to my wife gave a whistle, and we went off to bed under the down comforter to wrestle. But the fridge heard me exclaim as I walked out of sight, "Try that again, you bastard, and you'll be recycled all right!" John J.

Papazian lists a lager yeast for > his Sparrow Hawk Porter (p.200), however in the STYLE section he > states that porters are made with ale yeasts. Which is correct? > Is the recipe a typo or is this the particular style this brew is > after? Actually, a virus should be used; you can get a culture from America On-Line :-). Seriously, the Porter style calls for an ale yeast. But, according to Terry Foster in his book "Porter," Yuengling's Porter (from PA) is made with a bottom fermenting yeast and maybe this is the porter Charlie is trying to emulate in this recipe. Porter as a style had almost completely died out as a style in the beginning of this century and is only recently being revived. Thus each brewer ends up making his own interpretation of what the beer must have been like. - -- Jim Grady grady at hp-mpg.an.hp.com Return to table of contents

As I stated in my original post, I am not trying to support or promote Samuel<TM> Adams<TM> beers but I too like the hop character of his beers. I am looking at The Boston<TM> Beer<TM> Company's<TM> newsletter Volume 2, Number 1 - Winter 1994 and it talks about how Jim<TM> Koch<TM> and production manager David Grinnell hand select their hops. The article states that they travel to Germany each November to find the finest hop flowers. The article goes on to say "The hops will then be milled under cold temperatures and sealed in impermeable bags to protect their precious oils. They will be flown back to the Boston brewery where they will add their elegant aroma to Samuel Adams beers." So I guess that they hand pick their hops and then pelletize them for shipping and storing purposes. I hope that this helps clear the air. I was still surprised that they use pellets. Mike Montgomery mlm01 at intgp1.att.com P.S. I ordered the hops for $12/pound, 1 pound limit, the mailing address was: Noble Hops Boston Beer Company The Brewery 30 Germania St. Boston, MA 02130 They were selling 1200 pounds on a first come - first serve basis.

In response to a question by Chris Lyons regarding whether Jim Koch uses hop pellets or not, I responded to an ad in Ale Street News for a free pound of Sam Adams Hallertau Mittelfrueh hop pellets for homebrewers. It turned out to be a package of about 14 oz. if I remmeber correctly, but the package was a package of pellets. It said packed for Sam Adams. Therefore, based on this evidence, I would have to conclude that they use pellets somewhere in their process. Mike Return to table of contents

I'd like to rty some of the more exotic recipes but hate to spend the 20-30 bucks as well as time, carboy space etc required. Does anyone have information on how to scale down a recipe to about 1-1.5 gallons? I was thinking of using some green wine bottles as "fermenters." Would this be as simple as using proportionatley less stuff or will there be other issues to contend with? One thing that bothers me is how much yeast to pitch. I'm also thinking of starting my own yeast bank so creating from slants may not be a problem. I will appreciate posts or E-mail. Will summarize any E-mail comments and post if there is much interest.

Rolled oats, as Glen used, do not need to be gelatinized (cooked) before mashing, as this is done in the rolling (between heated rollers). The "Quick" oats are especially well processed. Just add them to your crushed grain and dough in as usual. The other thing you could do if you wanted to cook them first is use their heat capacity to boost the mash temperature, as in a decotion mash. Doough in at a lower temperature, perhaps a protein rest (122^F), then add the oatmeal. Of course, you'd have to compute how much your temp. would rise.

Date: Wed, 14 Dec 94 09:04:21 CST From: "Chris Williams" <inline at VNET.IBM.COM> Subject: The life and times of sugar I don't think there is a sugar FAQ yet, but here is some interesting information I found in a cookbook I just got. The cookbook, by the way, is a great alternative to homebrew for putting on the pounds! Reproduced without permission from "The Cake Bible" by Rose Levy Beranbaum, Sugar from beets and sugar cane is dissolved in water and the resulting syrup is boiled in steam evaporators. The substance that remains is crystallized in heated vacuum pans and the liquid (molasses) is separated from the crystals in a centrifuge. At this point, the sugar is know as raw sugar and contains 3 percent impurities. The raw sugar crystals are washed with steam and called turbinado sugar, which is 99 percent pure sucrose. The turbinado is heated to a liquid state, centrifuged, clarified with lime or phosphoric acid, and then percolated though a column of beef-bone char or mixed in a solution of activated carbon. This whitens the sugar and removes all calcium and magnesium salts. It is then heated until it crystallizes. This sugar is 99.9 percent sucrose and is known as refined white sugar. Refiner's syrup is a byproduct of the refining process. When the syrup, after many boilings, ceases to yield crystals it is filtered and concentrated into a golden-colored syrup. Lyle's packages it as Lyle's Golden Syrup. ************************************************************** Chris Williams inline at vnet.ibm.com ************************************************************** Return to table of contents

I agree that without any kind of analysis I don't really know what reduction was achieved. Still plan to check this via gas chromatography and will post results, shortly I hope. Getting to zero alcohol by this method would take a lot of heating, but the main objective was to reduce alcohol to a low level.

I saw the post yesterday about the pellets, and was aghast. The thought of receiving a pound of pellets horrified me and sent chills down my spine. My flesh crawled and...well, it bugged me anyhow. I ordered my pound about two weeks ago, and have not received them yet, so I immediatly got on the phone and called the BBC to have it out with them. I was prepared for the worst. The nice girl told me it would be four to six weeks for delivery of my hops FLOWERS, not pellets. I can now go on with my life. In closing (assuming the girl at BBC knows her stuff), I would like to ask those of you who must flame Sam Adams to please try to know what you are talking about rather than just assume the worst. If my hops arrive in pellet form, I will let y'all know and will apologize. Hop to it!! -- Jim Doyle ComputerBath products and services complete line of cleaning products and info Costa Mesa, CA Ph.

Date: Wed, 14 Dec 94 11:00:16 EST From: Spencer.W.Thomas at med.umich.edu Subject: Re: "Sparging" by any other name - would it smell as sweet?? Well, I know the OED is not the authority on brewing terms, but here's what it has to say about "sparge": 1. The act of sprinkling or splashing; a sprinkle or slight dash (of liquor, etc.). 2. Brewing. A spray of warm water sprinkled over the malt. And, in a second entry: 4. a. Brewing. To sprinkle (malt) with hot water. Also absol. b. To aerate (a liquid) with air (in quot. absol.). And, looking at the word derivation, it does not appear to come from German: sparge spard3, v. Also 8-9 Sc. spairge. app. ad. OFr. espargier or L. spargere to sprinkle; but in sense 1 answering to parget v. and having the earlier variants spargen and sparget. Thus, "sparge" really appears to refer to the practice of sprinkling or spraying water over the top of the malt, and not the "straining" or "washing" action, at all. =Spencer in Ann Arbor, MI Return to table of contents

The beer he markets is brewed at the F.X. Matt brewery in Utica, probably still the largest contract brewer in the country. (I believe it's brewed someplace else for the western markets, the Triple "Bock" barley wine is brewed in California, and some of the seasonals may(?) be brewed someplace other than Utica.) I've toured the place and have seen cases of pellets, but they could be going into any of a few dozen different beers. So, no, I don't have THE answer, but it wouldn't offend me if the beer was hopped with pellets--I use both pellets and flowers and have no complaint about pellets. But let's get this straight, Jim Koch doesn't make beer, at least not anything that I see in the store. If he does, I hope someone will correct me. Dana Edgell puts his signature humour on the "Good Times" thread: Why are those Canadians so damn funny? :-) :-) But, Dana, it's not the good beer _virus_ that can make things as blurry as you say they can be, just the _good beer_, like all those $2 23 ounce glasses of SNPA we drink here in Madison when we're not drinking the increasing variety of local micros.

It's really designed for flour >making only. No, no, no. The Kitchen Aid grain mill attachment can certainly be adjusted for cracking grain. Its grinding wheels are fully adjustable and can make flour as well as give a reasonably good crush on malted grains. It may not be as good as a roller type but it is sturdy, well made, and crushes about 1 pound a minute. I received mine about 2 1/2 years ago as a gift and have used it on about 25 batches so far with good results. I only get about 27-27 pts/gal/lb, but don't have a RIMS as Bob does, but could probably get more with a finer crush, but perhaps risk grain astringency (I have no noticable astringency problems now). This doesn't mean I would necessarily recommend one over a MaltMill, especially since the Kitchen Aid attachment is at least as expensive, but I'm satisfied with mine. Corona mills were also probably designed for flour making only. Bill Szymczak wszymcz at relay.nswc.navy.mil Gaithersburg, Md Return to table of contents

Date: Wed, 14 Dec 1994 13:50:44 -0500 (EST) From: Jim Busch <busch at daacdev1.stx.com> Subject: RE:high gravity brewing/Maltmill & DC Pils Paul asks: <I was wondering if anyone could comment on the practice of high gravity brewing < . I know commercial brewers use the technique quite a bit because of economic <concerns, but I am wondering if it has a place in homebrewing. < I am thinking that I would use high gravity brewing to avoid the blowoff <hassles that I often get when brewing ales (especially wheat ales) in carboys. <I figure I could leave about a 2 gallon headspace if I brew a extract or <partial mash ale and not worry about blowoff hoses, etc. < But, the ultimate question is: will high gravity brewing affect <the taste of the finished beer? In my opinion, it definetly has a place in brewing, either at home or in a bigger brewery. The important distinction I would make is the difference between high gravity brewing *and* fermenting, ala Bud, Coors, etc, and high gravity wort production, normal gravity fermentation. I routinely practice high gravity wort production and dilute this in my fermenter. It does take some practice and educated guesses in recipe formulation and the degree of dilution. Just last nite I brewed a pale ale wort of 17 Plato cast out wort. This was split into two fermenters, one was diluted to 9.5P for a bitter, the other was diluted to 14.5 for a full bodied pale ale. Obviously, you need to up the IBUs in a recipe to account for this, but it is a useful way to produce more wort in a fixed size kettle. What is very different is actual fermentation of high gravity wort and final dilution prior to packaging. This should change the character of the beer, mostly in the negative (fusels, esters, etc). If blowoff is to be avoided, I would say use a large open fermenter (aka HDPE trash can), or use two fermenters. RE: sparging terminology. Rinsing of grains in all grain brewing, period.

In the instructions, I advise siphoning into the carboy with a chore-boy pot scrubber and some mesh wrapped around the pick-up tube to filter the wort on its way. I wrote an article for Zymurgy last year that explained this technique in more detail. The net result is that anything that gets through the chore-boy, the mesh and the 1/4" siphon hose will not clog the 1/2" blow- off tube. Experience has proved this to be true. In the 10 years I've been selling them, no one has ever complained of blowing five-gallons of beer out on the floor. I'm sure I would have heard about it if they had.

Date: Wed, 14 Dec 94 08:15:12 PST From: jhall at sequoia.northcoast.com (JimHall) Subject: Long neck bottles, Gott coolers Hello Everyone, I have been lurking here since August and really enjoy reading all the advice you have given on homebrewing including the real technical/scientific stuff that sometimes I don't understand, but have fun trying to. Thanks for generously sharing your experience and knowledge with me and the other lurkers among us. I live on the coast of northern California where the summers are very mild (60 to 70 degrees) and so this summer I began my journey into to making homebrew. I made 9 batches. My original intention was to save money. In hind sight it was a kind of "Make your own swill and save." I had no idea what real beer tastes like and I'm not sure I do yet. Now money is not so much an issue as making super brew. This Christmas I've made up some labels and put together six different beers in six packs for some of my friends as Christmas presents and am looking forward to spreading the (homebrew) word. I would like to mention a few things I've learned that haven't been mentioned in the digest that may be helpful to other newbies. If you're having problems getting 54 bottles out of your batches the reason may be that your using long neck bottles. It takes 5 1/2 gallons to fill 54 long neck bottles. Long necks hold more than 12 fluid oz; more like 13 fluid oz. The other thing I wanted to mention regards replacing the stock Gott cooler spigot with one of those standard priming bucket spigot valves most of us are familiar with. If you take off the nut and remove the original Gott spigot valve, you'll notice the thickness of the wall of the cooler is about 1/4". This is enough thickness to tap threads into. If you carefully increase the diameter of the existing hole to just the point where the end of a standard priming spigot begins to fit inside, you can use the valve threads just like a tap to create threads in the wall of the cooler. The plastic in the cooler is softer than the valve threads. Then all you have to do is unscrew the valve, coat it and the threaded cooler hole with non-toxic teflon paste and screw it back in. The problem with just reaming a hole large enough to fit the threaded end of the priming bucket spigot through is that there, just barely, is not enough threads on the valve to catch the nut and the rubber washer. If, however, you thread the hole and add teflon paste you get a good tight water proof fit that doesn't need a washer. Also, without the washer, the valve nut screws on securely adding additional support. I did use the rubber washer as a template, so to speak. I centered it over the original hole on the outside of the cooler and used it to make sure the new hole was centered on the old, the right shape and size. I used a (battery) power drill with a small pointed, conical-shaped grinding or reaming bit that fits easily inside the original hole. You can pick up a similar bit at probably any hardware store.

Webb <rbw1271 at appenine.ca.boeing.com> Subject: Adding fruit to a fermented beer I have two batches of fermented beer that I wish to add fruit to. I intend to thaw the frozen fruit in just enough water to cover it, and use a blender or beater to chop up the fruit before adding it to a secondary fermenter, then siphoning the beer on top of it. Not being able to RDWHAH, I began to wonder if the aeration of the fruit and water mixture will lead to oxygenated alcohol after the introduction of the alcohol containing beer. Is this something that I need to worry about? I could skip the step about beating the fruit into a puree, but I'd like to get the mix as chopped up as possible. I still haven't decided which fruits to use, as I have strawberry, peach, blueberry, and cherry, but I don't suppose that the type of fruit matters. What is the consensus of the Net?

Date: Wed, 14 Dec 1994 17:38:47 AST From: "peter williams" <peter.williams at acadiau.ca> Subject: Making a stout I have some questions that have come up in doing some reading in preparation for making some stout. The first deals with brewing salts. Miller - gypsum lowers ph, calcium carbonate raises ph - dark grains tend to lower mash ph, therefore, adjust ph with calcium carbonate. Papazian - all stout recipes in TNCJHB call for gypsum additions. Who is right?(if either) Secondly, regarding dextrins and body: Miller - "myth that seems to die hard ....dextrins contribute to the body of a beer......de Clerk proved this false long ago" Papazian - "dextrins....tastless, yet add body and "mouthfeel" to beer" Jackson - "Dublin's upward-step infusion mash is geared to leave sufficient unfermentable sugars to provide some body." Body is what I'm after here. Should I bother with higher mash temperatures? Finally - I am using the Wyeast Irish(1098?) liquid yeast. Any suggestions as to appropriate fermentation temps? Basement is cool - 55F but steady. Upstairs -60 at night to 70 in day. Thanks Peter Williams pwilliam at acadiau.ca Wolfville, Nova Scotia Canada Return to table of contents
Date: Wednesday, 14 December 94 15:40:30 CST From: Alan P Van Dyke <llapv at utxdp.dp.utexas.edu> Subject: pellets & Koch Howdy-- I've noticed the thread about hop pellets & their possible use by the Boston Beer Co. I don't know how they hop their beer, but I would actually be surprised if they did use whole hops. There are two advantages to pellets: the little oil glands are crushed, releasing more oils & better yield, and they don't take up as much room. Can you imagine someone who produces at the level that BBC does trying to store a significant amount of whole hops for the coming year? That's a lot of room, especially if it's in a freezer. I would like to know, though, if there are any commercial brewers out there that do use whole hops, & if so, how they procure & store them. Koch claims to buy up a lot of hops during harvest, which means he gets them once a year. Do others just buy them as they need them? Just curious. I use pellets myself, but mainly because there's a lot of competition in the freezer with ice cream for space, & I feel that both whole & pellet hops are fine.

I use a standard racking cane and tubing setup in an orange carboy cap (the one that slips over the top with two stems attached) now here's the trick, in order to provide a positive pressure without having to huff and puff and blow my brains out I have a bellows type air pump (foot powered, blue plastic for blowing up pool toys, air matress, etc.) with a hose and a plastic tip that fit into the second stem on the carboy cap. This setup makes it very simple to push the beer from one carboy to another with a minimum of splashing if the tube on the cane is long enough. I use this for all my transfers. (To effectively clean the racking tube I simply put it on a carboy full of sanitizer and empty it through the cane and tube setup using the pump) Chris Cooper , Commerce Michigan --> Where ever you go <-- ccooper at a2607.cc.msr.hp.com --> There you are <-- Return to table of contents
Date: Wed, 14 Dec 1994 15:03:40 -0500 From: cole at nevism.nevis.columbia.edu Subject: eugenol Hello all. I have had a problem on my last two batches that resonated with a recent post and follow-up response by Al K. The last two batches in question were a Trappist Ale and brown ale. In both batches I have found a clovey-peppery aftertaste that was reminiscent of a weizen but not what I wanted to find in either a trappist or a brown ale. The description of eugenol included in the flavor-list recently posted and commented-on by Al matched my perception of the offending aftertaste extremely well. In particular, the peppery undertone stood out when I was bottling my last batch. So let's suppose I've created eugenol in my beer, the question is how ? Both batches were all-grain batches rather standard grain bills and with OG's in the appropriate range for the style. I don't have the exact values at hand, but I know they were what I was shooting for. In the trappist ale I used the yeast-lab trappist ale yeast and was willing (eager ??) to blame the flaw on the yeast or the fact that just after fermentation started, the outside temps. here in NY shot through the roof (early in summer) and I didn't get the beer into my fridge for a couple of days. However, the brown ale was fermented with the Wyeast scottish ale yeast in a fridge at 64 degrees F. It sat through a rather long secondary as I moved but I don't believe that's the source of my problem. One thing common to both of these batches (other than the equipment) is that I used wort saved from the dregs of a sparge to start the yeast. Since this wort came from the very end of a sparge, it was very turbid and in the process of sterilizing the wort I did not remove the hot-break that formed. So, my question is as follows: Can the problems I'm having result from propagating yeast in wort with hot-break and other "junk" (very scientific, I know) present. i.e. do these sources of "trub" potentially increase the production of this type of phenol ? I know that I could have an infection in my equipment or in the starter wort for that matter, so there's no need to tell me this. I want to know whether I should rule out the wort as a source for the problem. Thanks, Brian Cole Yorktown Heights, NY cole at nevism.nevis.columbia.edu Return to table of contents

Korzonas writes to Martin: >Finally, I'm afraid you got the data backwards... the >blowoff batch went *slower* and had a higher FG. That's how I read Szymczak's data from #1586, too. To me it seems less a question of fermenter geometry or temperature than of aeration. A carboy with a 3" headspace would surely be more difficult to aerate than one that is only ~30% full. More O2 at the start of fermentation means healthier yeast and a quicker ferment. Pitching rate would be another variable worthy of consideration. Was any effort expended to try to pitch 3/4 of the yeast into the more full fermenter? Bill, I don't have your original post from last year. Can you fill in any details about aeration method and pitching rate? Eric Miller Newport, RI Return to table of contents
Date: Wed, 14 Dec 1994 21:19:18 -0500 From: GubGuy at aol.com Subject: Siphon suggestion Been several posts recently about siphon problems.. Thought I'd offer a trick that works for me. I used to always get an air bubble in my tubing just below where the tubing fit onto the racking cane; starts small and gets larger as siphoning continues until there's no more siphon (sound familiar, anyone?). When this happens, just pinch the tubing (right below the racking cane), this somehow loculates the air bubble and pushes it on down the tube. Granted, there is a bit of aeration as the air bubbles up through your wort, but if you have wort dropping 6" through an air bubble in the tubing, I figure it's getting some aeration anyway. At least you son't lose your siphon. Hope this helps some newcomers; I haven't lost a siphon *since* I started using this method. On another note, I brewed up an all grain "Disaster Bock" last weekend. To make a long story short; incomplete conversion, stuck runoff, burnt hand, etc. Question: Was the stuck runoff do to having all that starch left in the grain? If someone wants to tackle this with more details, send email and I'll elaborate. One encouraging note: I learned MANY things this last batch and hope to never have this much trouble again.

This is not how gases work and a good thing for us humans too! Compared to the atmosphere, we're not very tall and if all the CO2 was at the bottom (near the ground) we'd all suffocate. If you "pour" CO2 into an air-filled container it *will* displace the lighter air (again, an O2/N2 *mixture*), but if you leave the container open to the atmosphere, CO2 will slowly move out and air will slowly move in till the concentrations of the gases are equal on the inside and outside of the container. This, by the way, is true even if you have a non-oxygen-barrier bottlecap on the container (i.e. CO2 pressure does not keep oxygen out of your bottles). Al. Return to table of contents
Date: Wed, 14 Dec 94 22:16:32 EST From: erict at VNET.IBM.COM Subject: 5 litre mini-kegs summary Thanks to all who responded to my query about mini-kegs (I was wondering if the Fass-Frisch system I was looking at was worth going for). The response was generally favourable; out of the 6 responses I received I heard "working well," "good results," "very pleased", "reasonably happy" and "like 'em a lot", and only one "experience has been mixed and ... not sure I'd buy them again." (Not all responses were specifically about Fass-Frisch, but the comments seemed general enough to apply to all mini-kegs.) Advantages reported were: less time spent bottling; ability to pull as little or as much beer into your glass as you want; convenient to take to parties, etc. Disadvantages: CO2 cartridges do not last very long (mentioned by a number of respondents; metal taps may help them last longer than plastic; Fredrik from Sweden -- Fredrik.Stahl at mathdept.umu.se -- would like to know if anyone knows of rechargeable cartridges); some reports of kegs leaking or bulging; if you only have one tap you can only have one kind of beer on tap at a time; takes up lots of room in the fridge. Hints: Use less than normal priming (usual suggestion was 1/2 normal -- I have a question: What do people do when they keg part of the batch and bottle the rest? Prime bottles and kegs separately?); don't use chlorine to clean (B-Brite was suggested -- and a note that it is quite difficult to drain the keg after cleaning and "neat things" might grow in it if left unused for a while); make sure the keg is chilled before broaching it or risk vast amounts of foam in your glass; and only use the CO2 in short bursts when needed. Two people also referred to me to the mini-keg FAQ on Spencer's WWW Beer Page at http://guraldi.hgp.med.umich.edu/Beer/beer-page.html, but since I only have e-mail access for the foreseeable future I'm afraid I'm going to have to give that a miss for now. There was also a reference to a lengthy discussion earlier this year that ought to be in the "archives." So once again, thanks to Fredrik, Pat, Bob from Badgerspace, Aaron, Spencer, and Jerry for the advice and tips, and Gene, I hope this answers your questions as well as it did mine. Based on the response I think I'll take the plunge and experiment with the system. If anything interesting results, I'll let you know in further posts.

Date: Wed, 14 Dec 94 22:56:00 EST From: anthony_meehan at Merck.Com (Anthony Meehan) Subject: Intermolecular forces and Gravity? I have to disagree with Dr. John Pratt (hbd #1604): Carbon dioxide displaces oxygen initially as it fills the head space in your fermenter, but eventually the second law of thermodynamics comes into play and oxygen will diffuse back into the carboy. If gravity allowed the heavier carbon dioxide to displace the oxygen at ground level in the atmosphere we would have a difficult time homebrewing as well as anything else. The same holds true for the alcohol in your beer: the concentration is homogeneous throughout the fermenter. Specific gravity is not a precise measurement of alcohol content, and certainly not to 0.003. Tony Meehan Return to table of contents
