To me, the hop character of each brand is almost identical (as well as being almost completely muted). Do they all use the same hop variety, or what? Bill K. Return to table of contents
Date: Mon, 6 Jun 94 08:07:16 EDT From: mlobo at sunwr23 (Michael T. Lobo) Subject: keg fridge comments Greetings: I finally began using my keg fridge last weekend - what a pleasure it was! I bought an OLD used fridge for $50, bought the tap hardware from Superior Products for $30, installed the tap through the door of the fridge and now have my favorite brews on tap. Using a "real" tap instead of the cobra tap is a difference like night and day. I was forever playing with dispensing temps and pressures with the cobra. The first beer I drew I used 10 psi and out came a great ale with just the right amount of head. Perfect. Needless to say, once my friends discovered my new toy, the first keg went quite rapidly {:^) Bottom line: If you've started kegging and are disappointed with results, make that extra investment, get a fridge and a tap and enjoy. BTW - I bought 3 kegs from St. Patricks in TX for $33 + s/h, and even though they are pin types, they are ~2 inches taller than the kegs I had. Just a data point if you try to lay the kegs in the fridge. regards Michael ___________________________________________________ Michael T. Lobo 508 549 2487 Foxboro Co.

Date: Mon, 6 Jun 1994 09:24:22 -0300 (ADT) From: robinson at orbit.acrso.ns.ca (John Robinson) Subject: Autolysis My thanks to all who responded to my last question on Scottish Ale yeasts. Especially to Jeff Frane for providing exactly the information I was looking for. Did anyone add that to the Yeast FAQ? That was the first place I looked.... In reading Foster's book on Porter over the weekend I came across a comment from him that ale yeast was more prone to autolysis than lager yeast. Sorry I can't be more exact than that, I'm at work and I don't have his book in front of me. My experience to date would tend to suggest the opposite is true. I've never had a batch of ale yeast autolyse on me, but I have had a couple lagers go after sitting at room temp for three weeks or so.

Date: 06 Jun 1994 10:20:06 -0400 (EDT) From: S29033%22681 at utrcgw.utc.com Subject: Washing machine mashers I thought of the idea of a washing machine masher a couple of years ago while I was considering building a RIMS (recirculating infusion mash system after Rodney Moris' article in Zymurgy gadgets edition). I thought that a washing machine could probably be modified to brew. However, after thinking about it and bouncing the idea off a fellow brewer and colleague, I decided that the washing machine would need too many modifications to be worth the trouble. One of the major modifications would be the agitator hub and transmission -- the seal between the hub and the transmission is not good enough to prevent oil or grease from getting into the mash. Although this does not happen often with clothes, it does happen. The mash might even cause this to happen prematurely. I don't believe that the pumps or hoses are of food grade type either. I am not saying that it can't be done. Being an engineer I often think that there isn't anything that can't be done. The effort or cost is usually what decides what will and will not be done.

Date: Mon, 6 Jun 1994 09:34:01 -0700 (CDT) From: Lee Bertagnolli <bertagno at eagle.sangamon.edu> Subject: Cheese Vat as mash-tun? I have acquired a 30 gallon SS cheese vat. The vat is cylindro-spherical in shape, with a bottom drain, hinged lid, and a steam jacket. It came with various screens, cutters, and molds for making cheese, but the thing that caught my attention was the integrated steam jacket (also that fact that the unit was the right price -- free :-). The steam jacket envelopes the the bottom 75% of the tank, and in effect, makes this thing a giant double boiler. There are pipes coming out of the jacket, for steam in and for steam out. Can this beast be used as a mashing vessel? It would seem to me that it would be ideal for step-mashing. Does anyone have some thoughts/suggestions in this regard? **************************************************************************** * Lee Bertagnolli bertagno at sangamon.edu * * Sangamon State University "Seville der dago, towsin bus essinarow." * * Springfield, Illinois "Nojo, demmit trux, summit cowsin, summit dux!" * **************************************************************************** Return to table of contents

Date: Mon, 06 Jun 1994 09:03:15 MDT From: ueymids at trex.oscs.montana.edu Subject: Pale ale? I'm on my 8th or 9th batch of homebrew and have made only darker beers so far. I've enjoyed, browns, porters, some splendid stouts and bitters, a dark steam etc. But I finally got the urge for a pale. I attempted an IPA using Charlie P.'s recipee but I used amber malt and so missed the piss-yellow color I was hoping for. So I have tried again... My problem is that this batch, currently sitting quietly in a carboy, waiting for me to get around to bottling, was supposed to be an IPA--- But it looks like a nice dark brown. I brew from extract and used Ironmaster's IPA beer kit. I added 3 lbs of light Steinhart Co. malt extract to get 7lbs total. The shock came when I poured the Ironmaster malt into the boil, I thought it didn't look pale.. oh well. It still doesn't look pale. Is it possible that they mislabeled their malt? Has anyone had this problem, should I write to Ironmaster? Also, perhaps once I bottle it the beer will magically transform into a piss-yellow pale... (P.S. I also missed the starting gravity for an IPA, mine was 1.040 not the 1.070 I wanted, I geuss I should use about 10 or 12 lbs of extract next time). Derek Sikes, Bozeman MT.

I am a relatively new homebrewer (about 8 batches) and I need to know if twist off returnables are okay to use for homebrewing. I recently acquired several from a friend who wants to contribute to my hobby to help me "get rid of all that beer I'm making". I have heard that they are okay and that they are not. I tried capping one and it seems to be pretty tight but I am reluctant to waste a whole batch testing it out. Any suggestions would be appreciated.

Date: Mon, 06 Jun 94 11:45:26 -0400 From: Al Folsom <folsom at fp.com> Subject: Extraction Rate Question Folks - After yesterday starting my second all-grain batch, I'm looking for a little wisdom on extraction rates. I seem to be getting rates of about 25, and was expecting more. Yesterday, for example, I made a brown ale with: 8 lbs. Kleges 3/4 lb. Crystal 1/4 lb. Chocolate 1/4 lb. Black Patent I was expecting a SG of about 1.046 or above, and ended up with 1.042. Granted, 1.042 is OK for a brown ale, but I'd like to be able to predict better, and understand what is going on with the mash. I did a simple infusion mash at approx 152 degrees for 90 minutes. I used a Gott Cooler with the Phils' Phalse Bottom. (see note below), and sparged with 4 gallons of 170 degree water over the course of an hour. I did not measure PH, but know that my well water is very hard, and perhaps a bit alkaline. Any clues on how to improve my yield? Note: As a scout leader, and with three kids of my own, I was hesitant to modify the Gott in such a way that it couldn't be used as a normal cooler. I purchased the Tomlinson faucet that is available by mail from Gott, and by drilling it out ever so slightly, got a snug fit to the hard plastic tubing that is used for bottle fillers, etc. A cut a short piece of this, mated it to some siphon tubing, and mated that to the false bottom. This unit can be easily removed, is secure when installed, and leaves the cooler available for other uses also. Note 2:I didn't receive many (only one) responses on the BrewTek yeast question a few weeks ago. Come on, anybody use these strains? any one you particularly like, or dislike? Any problems culturing? Inquiring minds want to know! (Yeah, that phrase grates on my nerves too...)

Date: Mon, 6 Jun 94 10:28:52 PDT From: Karl Elvis MacRae <batman at cisco.com> Subject: Questions on strength; more malt? Honey? Other options? I bought supplies the other day to make a stout, and then later decided I wanted to make the brew a little stringer. I've got 6.8 lbs of Laaglander dark malt. The question is, what's the best way to get a little more strength without producing a lot more sweeteness? I was thinking of adding more malt, or maybe some corn sugar? The guy at the local brewshop said 'Or you can try honey, but I've never tried it with a stout', and went on to say that honey gives strength without a lot else. So? Any opinions? I would like to produces something quite strong, but I don't want somethings hugely sweet. I know sugar would work, but I'm leery of sugar; it seems, I dunno, *fake* somehow. So what's the best way? Thanks..... (Oh, BTW, thanks to all those who helped me out on my 'is it stalled' question. I bottled yesterday, it tastes good already, can't wait to see what it's like when the bottles are ready!) -Karl - -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Karl Elvis MacRae Software Release Support Cisco Systems batman at cisco.com 415-688-8231 DoD#1999 1993 Vulcan Eighty-Eight -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "Hi, you look different!

Date: Mon, 6 Jun 1994 11:16:02 -0600 (MDT) From: limd at plasma.arraytech.com (Davin Lim) Subject: Q: Quality of Vienna/Munich malts? In reading George and Laurie Fix's book on the history and brewing of Vienna style beers, they make it quite clear that the quality of the base malt in the grain bill is of the greatest importance when brewing this style of beer. They emphasize that good quality pilsener malt (e.g. of the Moravian variety) should be used and that as-good-as-possible crystal malts be used to obtain the proper color. It is mentioned that historically, Vienna malt was indeed high-quality (e.g. Moravian) malt that was kilned to a higher temperature and the color was already in the base malt. In modern times, however, "Vienna" malt is produced by using a lower-quality base malt and therefore wasn't very suitable for producing a good quality Vienna beer when used as the sole grain. "Munich" malts, as we know them, are also specuated to be made of lesser barley varieties (although I'm sure the big German brewers could get exactly the grain they want, just us small folks have to take what's available.) Same comments apply here. The authors hint that there may "soon" become the recognition among maltsters that a Vienna malt made from Moravian(esque) barley has a market, and a beer could be made that much better. Does anybody know if such a malt is available? It would be good to try brewing with such a grain and compare it to the pilser/crystal combination. ................................. * Davin Lim * * limd at arraytech.com * * Boulder, Colorado. * .................................

It should filter better than the funnel screen disc. I knew I'd find other fish-geeks here. Somehow the two hobbies seem to go hand in hand, what with the focus on microrganisms, all the siphoning, etc. Of course, with brewing, the siphoning *tastes* much better! =B^) Now, this is just a guess, but I'd say that using a filter like that would be a bad idea. I would think it would be *too* fine; you'd loose too much of the matter in your beer; and with it, a quantify of your yeast. Also, it would clog very quickly; these things aren't that good an handling large particulate matter. So you'd keep having to rinse it.... -Karl -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Karl Elvis MacRae Software Release Support Cisco Systems batman at cisco.com 415-688-8231 DoD#1999 1993 Vulcan Eighty-Eight -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "Hi, you look different!

They had a variety of 2 row grains. They had American Pale Malt, German Pale Malt and Belgin Pale Malt. They also have a similar grouping of Crystals and Wheats from differnt countries. The store told me that they are basically all the same, just from different countries. Is this true, or does one country make a better grain than the other. What are the major differences? The prices were the same or only 5 or 10 cents a pound difference. Larry KMYH09A at prodigy.com Return to table of contents
Date: Mon, 6 Jun 94 13:27:05 CDT From: wood at ranger.rtsg.mot.com (Dan Wood) Subject: Kegging Thanks, Toronto Brew Many thanks to those who sent email to help with my foaming problems with my first keg. Things are going well now, so I'll try to summarize my findings. I realize that these generalizations are inherently limited, and you experienced keggers will cringe, and perhaps flame. Nonetheless, here goes, for the benefit of other neophytes: 1. The dispensing temperature and pressure must be fairly constant for about 1 day prior to dispensing. This may require venting of carbonating pressure well in advance of dispensing. Dispensing at 8 PSI at ~50F works well for me. 2. A partially dispensed keg should receive additional CO2 pressure prior to storage in a warmer environment. If the keg warms without added pressure, the CO2 will come out of solution and the beer will go flat. Storage at 20 PSI is working OK for me. Extra pressure, even up to the 40 PSI I carbonate at would be OK, but would require additional time to decarbonate/depressurize to dispensing levels, a waste of time and CO2. 3. It is very easy to lose track of consumption while drinking off a keg. Don't try to gauge by the accumulation of empties! FYI: I'm keeping the in-use keg in about a foot of icewater in a 5g bucket, and shopping desperately for a fridge. My basement stays cool, if you store a keg in a warmer area, you may need higher storage pressure. Also, next week I'll be in Toronto, at the Hotel Plaza II on Bloor street. I may not have a car. Any good spots in the area? Please respond via email. Stay away from my wife. Dan Wood, sovereign FVHAA. wood at cig.mot.com Return to table of contents
Date: Mon, 6 Jun 94 14:36:02 EDT From: Steve Scampini <scampini at hp-and.an.hp.com> Subject: Reverse Engineer My recent request for a extract Duvel recipe yielded one helpful bit of information but no recipes. While I would hate to break up the fascinating "how clean is my mouth" suction series on starting siphons, I thought the playful minds of the digest might be interested in discoursing at length on how they would go about reverse engineering a particular beer, say Duvel. What I have learned to date is that Duvel uses two hops Saaz and Styrians (sp?) and two (!) yeasts, one for bottle conditioning only (implying that culturing from the dregs may not give good results(?)). Other things I know are: 8 or 9 % alcohol in the bottle golden yellow color tastes good If you guys have not tried this beer, it is worth looking for IMHO. I have had the good fortune of trying it in Europe (read fresh and inexpensive). If I remember correctly Michael J. gives it four stars **** in one of his books i.e. a world class beer.

I brewed some beer in 1982 and bottled it using priming sugar for carbonation, gelatin for fining and ascorbic acid for preservative. I ran across a six pack in 1988. It was *still* good! I couldn't believe it. The only thing that concerned me was the color of the cork under the caps. The cork had turned almost black. It tasted good anyway, and I suffered no ill effects. A few years later, I actually drank the last bottle. I don't know if my experience is typical or not, but I hope it helps. Cheers! Return to table of contents

A couple of recent posts complained about not being able to get into the Homebrew Archives at sierra.stanford.edu. Well, the ftp software limits the number of simultaneous ftp connections to five and somehow it lost count and got stuck thinking that there were five logged in when there was nobody home. I've reset the count and connections are pouring in. There's probably some pent up demand but you should be able to get your files now. Personally, I think that poor thing just got tired and wanted to take a break. For the month of May we had over 13,000 ftp connections that transfered over 1.8 Gigabytes of data. Almost all of this was beer related. Finally, the department is going to reorganize the computer facilities here and there is a 50-50 chance that the archives will have to move. If and when this happens I will try to find another place locally that I can shift to. If that is not possible, I will find another site to take on the job before we have to close. Don't worry, any change is still several months in the future, and I have hopes that the archives will still be welcome under the new setup.

Date: Mon, 6 Jun 1994 15:10:28 -0700 From: Don Put <dput at csulb.edu> Subject: "Misinformation" revisited >From: Jim Busch <busch at daacdev1.stx.com> >Subject: RE: tannin leaching by boiling water, free ads in BT >I just got done skimming this misinformation . . . ^^^^^^^^ Perhaps if you had READ the complete article, you wouldn't have jumped to such needless conclusions. >I got pretty peeved for two reasons, one is that "tips" like these have >no basis in brewing science and are contrary to accepted practice, >especially with regard to increased leaching of tannins from the lauter tun. In theory, of course, you are right. However, the words "accepted practice" leave the resonant sound, in my mind, of lemmings running for the cliff. Granted, there has been a great deal of advancement in the brewing trade, and craft for that matter, by the careful study of processes. We have all gained a fair amount of control over our hobbies as a result of this, but I think there is always room for new ideas and new ways of approaching things. The folks who brought us lambics, pilsners, and steam styles of beer went against "accepted practice." Of course, they were concerned with different types of fermentation techniques, and we are dealing with sparging techniques here. If you had read Jack's article carefully, you would have stumbled across the words: ". . . but if you use boiling water in THIS system, the average temperature will be well below 170F and you will be lucky to keep it above 150F" (my emphasis). Jack is merely stating what he has found to be true with regard to the easy mashing system. I lauter in a Gott cooler and I get very little temperature drop, but I imagine if I used a kettle the heat transfer would be much greater. Therefore, I would need to boost my initial sparge water temperature, wouldn't I? The key word here is obviously "this," which is used as an adjective modifying "system" in Jack's article. This would lead me to conclude that Jack did not mean that boiling water sparges should be used in EVERY system. Jack's article was not meant to be "brewing science" only recorded observation as it relates to the easy mashing setup. >Secondly, the "article" is basically free advertising for JSP and had >no buisness being in the articles section , it belonged in some product >review area. While there were references to obtaining said easy mashing system from Jack Schmidling Productions in the article, there was also a comprehensive parts list that anyone with a little motivation could have used to assemble all the necessary parts, i.e., build their own easy masher. Also, you'll notice in the article it wasn't referred to as the EASYMASHER(tm). The "article" as you call it appeared in the section reserved for brewers entitled: "Brewers' Forum." Which, in past issues, has brought us such notable contributions as: "Modifying Half_Barrel Kegs for Use as Brewing Vessels," by Martin Manning "A Three-Tiered Gravity-Flow Brewing System," by Bob Caplan "Beer Tree: A Three-Tiered System with Roots in Simplicity," by David O'Neil and many others. All of the articles that have appeared in this section of the magazine are written from the [home]brewer's perspective. Hence, the designation "Brewers' Forum." I'm sure the editor was very careful to put Jack's article, as well as those mentioned above, in this section because they really aren't written to be "technical" articles. They are examinations into the tools of our trade as it relates to the home brewing scale. My reading of Jack's article suggests that it had every right to be included in the "Brewers' Forum." However, it is ultimately the editor's decision, and I happen to agree with it. >I'm sure the "Oracle" has something silly to say about all of this. Perhaps, but so do I. And it seems that jumping to conclusions based on "skimming" only perpetuates "misinformation," which is silly in itself, isn't it? >Good brewing, That's the point, isn't it?

Date: Mon, 6 Jun 94 16:14:54 MDT From: Randy M. Davis <rmdavis at mocan.mobil.com> Subject: Shelf life >Phil Miller asks: >How long can one expect a batch of brew to keep after it is bottled? What could >one add to make it last longer that wont kill me or the beer? On January 12, 1993 I bottled an attempt at a Belgian Wit in which I used a bit too much coriander for flavoring. I found the flavor and aroma off-putting and just left the whole works on my basement floor where the temp is 55-60 F. This past weekend I decided to check it out and found that the coriander is less offensive to me now and I can drink it. Obviously this was a clean brew as it is crystal clear and quite stable after 18 months in bottle. Slightly over- carbonated (about the same as most commercial beers) but good. I used only malted barley, wheat, yeast and a very small addition of hops along with coriander and orange peel in this brew. Initial gravity was ~1.044. Anyway, my point is that clean homebrew stored in a cool dark place can have a very long shelf life without any additives although most will be at their peak fairly early. - -- +-------------------------------------------------------------------------+ | Randy Davis: Mobil Oil Canada Calgary, Alberta Canada | | rmdavis at mocan.mobil.com | | Phone (403) 260-4184 Fax (403) 260-7348 | +-------------------------------------------------------------------------+ Return to table of contents
Date: Mon, 6 Jun 94 18:35:16 EDT From: Nancy.Renner at um.cc.umich.edu Subject: Cliff Tanner explains "Shaken Peptides" >From *Jeff* Renner Cliff Tanner has E-mailed me the following about his "shaken peptides" passage in the recent Zymurgy (assume I put <'s in front of every line): As for the inadvisability of shaking a keg to carbonate, there was a long thread on CIS awile ago about this. I thought I had that archived, but can't seem to find it right now. In general the consensus was that shaking might indeed be bad for the beer -- and since it was unnecessary anyway, why do it? My first inklings about this came from the shaker trays in commercial beer laboraties. in support of that the following was presented by David Klatte, who is a commecrial brewer: <Given enough time all beer will oxidize, creating off flavors and haze. Heat and agitation speed this process up tremendously. Beer is "force aged" in analytical laboraties by heat and continuous agitation.> <Beer has a finite ability to create a good, foamy head. Every time the beer is agitated in the brewing process, some of that foaming potential is used up. Excessive foaming in the brewery leads to a beer with an anemic, rapidly collapsing head.> Guy Hagner agreed: <<It has been my understanding that head is formed by medium sized peptides. I had always figured that as long as the peptides fell back into solution the head forming ability would be retained. But your reply indicates that many of the peptides are being broken in the head forming reaction. This also makes good sense now that I think about (it is exactly analgous to overwhipping egg whites).>> And our brewing experience tells of the beer that carbonates well at a certain pressure while another won't. Simple deduction over time would lead one to suspect the OG of the beer and hence (indirectly) the amount of protiens. And finally, it isn't even necessary -- the same results can be had with a couple days more time -- so why even consider doing it? Hope this makes sense. ==Cliff Tanner, Braukunst Relayed by Jeff Renner Return to table of contents
Date: Mon, 6 Jun 94 18:37:28 EDT From: Nancy.Renner at um.cc.umich.edu Subject: Malting,pts/lb/gal,trub, filtering, fining, keeping beer >From *Jeff* Renner In view of the interest here recently on malting, let me point out two Zymurgy sources that I have used over the years for direction in malting wheat, though they are actually for barley. The 1985 Special Grain Brewing Issue (8:4) contains a non technical "Primer on Malt by The Non-Technical Staff at Great Western Malt" that is a good general guide to malt, and "Home Malting for Homebrewers" by R.C.Dale, which is detailed and specific, and includes Dale's malting cabinet/kiln. The whole issue contains many good articles on grain brewing. I think this it is still available from AHA. Mark Alston points out that he gets better extract by slowing his sparge rate down to a gallon/15 minutes, while I suggested 5-6 minutes/gallon maximum. I think it's a question of how much time one has to devote to sparging. I generally pull 9-10 gallons for 7-1/2 brew, so that's a lot of extra time. My efficiency is around 30p/lb/g, where Mark's is around 35. I use an insulated and caulked Zapap, and used to get around 33 when I used a Corona Mill, but I sometimes had to wait to let the sparge flow. Now, using a MM(tm!) roller mill, I have to keep the outlet turncock at about one half. I'm sure that both a slower sparge and finer grind would improve the efficiency, and I'm still considering how or if to adjust the roller settings. I use a friend's, so it's not that easy. Sorry, Jack, I know I should buy one of my own. %^) It's a series of trade offs that I still haven't decided on. Speaking of points/lb/gallon, Larry Kelly asks when to figure this, in the boiler or in the fermenter. I take at the fermenter. This, of course, lowers my value. I always lose a fair amount from my early estimate when the boiler if full after the sparge (I do cool my sample). I would guess that most of this is due to loss in hops and trub. However, you report 29 at the beginning of the boil, 26 at the end, and 20 after dilution. Something here isn't right, and I don't think it is all due to the lack of linearity when diluting. Someone else (Martin Manning?) needs to help on this. Speaking of trub, Larry also asks what the chunky stuff is that settles out in his primary. That, Larry, is cold break, which, with hot break, is coagulated and precipitated protein collectively called trub. Hot break should be left behind in the boiler but some cold break is actually beneficial for the early yeast growth. Miller suggests you remove it after an initial settling period (like overnight), and Papazian says remove it if it bothers you. I usually don't bother. I'd be leery of using a sponge aquarium filter because I don't know what's in it. I do filter the last of my wort of hot break. I "whirlpool" in the boiler before using my counter current cooler, then take the last one or two quarts that I can't run off cleanly and filter it (now cool, so no HSA) through a square of clean cloth tied over a food grade plastic bucket. I sometimes even squeeze the last part. Then I reboil and cool it and add it to the fermenter. I used to let it settle in a jar in the fridge overnight as some author recommended, but find this is better. Larry also wonders what the proper amount of sparge water is. I generally prepare about as much as the final volume I want. Then I usually have enough to keep sparging until the pH rises up toward 6 and/or the SG drops below 1.005-008. If your efficiency was better that day than expected, the extra bitter wort that doesn't fit in the fermenter can be saved for priming or a starter. Or, you can make a little stronger beer than you figured and dilute it later. Another question Larry has is about fining agents. I like gelatin, although isinglass has intrigued me. At racking (either into a secondary or tertiary), I mix a 1/4 oz packet (unflavored!) in a half cup or so of cold water, then raise the temp (nuking works well) until it becomes clear - don't boil, it breaks it down and it's useless. Then I siphon a bit of beer into the mix and siphon it to the new container, making sure it's well distributed. It usually drops clear within a day or two. Using this method, I can count on enough yeast for bottle conditioning, but with a yeast layer on the bottom of the bottle about the thickness of a coat of paint. Larry, with your inquisitive mind, it sounds like you'd really enjoy a good brewing book. Check my note in HBD 1441 for recommendations. Phil Miller want to know how long a beer should last in the bottle and what he could add to his beer to make it last longer. Phil, it's more what isn't in your beer - bacteria, wild yeast, oxidation. Take care in your procedures and store cool or cold out of light, and it can last a long time. Although lager are best fresh from lagering, ales can actually improve, especially strong ones. I recently opened a 13 year old dark ale made with extract and *dextrose* (we didn't know so much back then) that was still in fine condition, although it had fermented out very dry and was highly carbonated. Eric Miller wonders about spoiled canned extract. Phil, I've seen enough swollen cans to know it's possible, especially if the factory didn't process them right. The older they get, the more chance they have of going off, and they certainly aren't going to improve. I'd sure move that can from 85^F to a cooler place! Jeff Return to table of contents
Date: 6 Jun 1994 17:25:20 -0800 From: "Turchik, Robert J" <rturchik at msmail2.hac.com> Subject: Rootbeer fizzle With all the great success that I have been having with my homebrew beer kit I received as a Christmas present, my wife and children talked me into trying to make some home made Rootbeer. Here's what i did... Brought 5 gal of water to a boil then added rootbeer extract and 4 lbs. of sugar cooled to 75 degrees pitched 1 package of champagne yeast let sit for a week then bottled and let sit for 2 weeks. Then when we poured it, it fizzed up real fast and it went away just as fast, there was no foamy head like you get with a good Rootbeer. when we smelled it , it smelled like yeast. finnally we tasted it and it had a bad after taste of yeast. Did i do something wrong?????? Can anyone steer me in the right direction for my second attemp?????? Thanx, FIZZLED OUT Return to table of contents
Date: Mon, 6 Jun 1994 17:51:21 -0700 (PDT) From: Phil Brushaber <pbrush at netcom.com> Subject: Attention Mathematicians! Has anyone come up with a formula regarding the relationship of the rise in Origial Gravity needed to balance a reduced amount of sparge water to result in the same Original Gravity in a standard recipe? I've got a pretty cheap source of grain, but during these summer months my time is at a premium. I have been making some pretty high gravity brews which I have to boil down from 9 -10 gallons down to 5-6. I'd like to cut down on the volume to boil by cutting my sparge back, but of course want to keep the gravity that the recipe calls for.
