---------------------------------------------------------------------- Date: Mon, 18 Aug 1997 15:59:02 -0700 From: Andy Walsh <awalsh at crl.com.au> Subject: Jethro and LABCO I'm not sure what has been posted here (immediately before this post) concerning Rob Moline and LABCO. I have some idea, so will try and summarise: Rob has worked for years at LABCO, with long hours, poor salary and a general manager with a bad attitude. He has transformed the brewery from one that produced nothing but infected beers to one that produced gold at one of the world's toughest beer competitions. He is moving to Ames, Iowa, officially because his wife has been offered a good job there, but unofficially because he has had enough of the lack of appreciation and poor conditions he gets at LABCO. He has supplied (free of charge) much of the paraphernalia at the brewpub that provides the atmosphere. After giving notice to the owners, and getting the OK to take all his possessions with him ("Just leave the bobcat"), the head chef and general manager have accused him of theft and reported him to the police when he tried to load all his gear into a truck, leaving the pub without any character (much the way it was in the first place, heh Rob?). The police have since determined it is a civil, not criminal matter, but there remains potential lawsuits from this angle, but also on who gets the medals for the competitions he has entered (and largely paid the entry fees for himself anyway). It's too long a story to tell here, and I'd probably get lots wrong anyway, but he is in a real pickle and needs our support. Although we have never met, or even spoken on the phone to each other, Rob must be the most generous man I know of, and the keenest anywhere in spreading the word of craftbrew. Beerwise, Australia is kind of in the situation the USA was 15 years ago (except for the exorbitant taxes here!). The market is dominated by mass-produced pale lagers (30% sucrose). Brewpubs and microbreweries are in short supply: those that exist are soon swallowed by the Fosters juggernaut, and to be honest, often have quality (control) problems anyway. Rob knows this, having lived much of his life in this country. Anyway, he has sent me and my friends here, at great expense to himself (several hundreds of dollars!), many samples of beers he has made, partly for our feedback (as if he didn't already get enough of that from his customers and peers in the industry!), but I think mainly just to give us a taste of the revolution that has happened in the US, that we are yet to experience. He sent me hand-counter-pressure-bottled samples of the original GABF gold medal winning barleywine, *before* the competition. He even sent me a sample just a few weeks ago, a year later, of the original brew! He has sent me samples of many of his other beers, tons of beer glasses and beer magazines - all unasked for. And all his beers were outstanding. He was even prepared to donate a free keg of barleywine to a going away party for Dave Draper (now in Dallas), if I could organise the freight in time (I couldn't). And whatever you do, don't ever tell him you're coming to Australia (as Dave has - twice!), as he'll load you up with beer, glasses and magazines to send to me once you get here. Of course I would have loved to guzzle it all myself, but I have taken it in the spirit that it was sent, and distributed it amongst my friends, and organised special tastings and judging sessions, to provide some of the feedback he wanted. I don't know all the details of the problems he has had at LABCO. I know from my own dealings with him that he is of impeccable character and is a victim of his own generosity and conviction to improving the craftbrew scene. What an indignity to be accused of stealing your own stuff after being promised for years by the manager to buy it from you! And since when were they responsible for the prize-winning beers he has made? I humbly offer Rob any support I can (whatever that can be over the miles - maybe just moral), and urge any other readers he has helped over the years to do the same. I'm surely not the only one. Hopefully it will all turn out well soon, in Ames, Iowa, and Rob will have his OWN brewpub and brew the way he wants, and run the show the way he wants. If anyone deserves that, it's Jethro.

Dembskey says his SG is rising after fermenting= instead of falling. You have discovered one of the great pitfalls with using hydrometers to t= ry to find out if the fermentation is finished. The CO2 bubbles in the bee= r are coating the sides of the hydrometer and making it rise. Pour the beer= back and forth several times to degas it and spin the hydrometer in the cylinder filled with the degassed beer and read *quickly*. The other pitfall with using the hydrometer with fermented beers is that different beers finish at different SGs because of the varying dextrin content. A better solution is to determine the remaining glucose.

Date: Mon, 18 Aug 1997 23:15:45 +1000 From: "Andy Walsh" <awalsh at crl.com.au> Subject: hops again >From Dave Burley: >> The same variety grown under different conditions >>will also brew differently, so forget about >>the anecdotal evidence. "Or is this myth based on the incorrect identification of the hop variety? I have read that the Hallertauer is the only hop that produces the same quality in the US as Germany. Maybe the reason is that it is the same plant and others were incorrectly identified - perhaps on purpose??" In the Stucky paper (JASBC 97), they have individuals describe the smell of 15 samples of raw hops (including US Tettnanger and Fuggle). The descriptors are processed via principal component analysis and the oils analysed via GLC. They discovered that the first principal component correlated well with myrcene which was described as fruity, floral, pine and sage. ie. myrcene appears to provide the single greatest component in differentiating the smell of raw hops. The panel could differentiate Fuggle and Tettnanger by smell (although they are pretty close). The GLC analysis shows Tettnanger to be consistently 10% higher in every component of the GLC analysis (about a dozen). Since the ratios of the oils are the same, I believe that Colin Green of Wye would say they are the same hop (OK - speculation!). Different growing conditions produce different amounts of myrcene. Myrcene levels increase with maturity. The Stucky data would seem to indicate that the Tettnanger is a more mature flower of the same variety as the Fuggle. (they make no mention of this though). So, - myrcene provides the greatest differentiator is distinguishing raw hops. and - myrcene levels vary greatly with flower maturity before picking (and growing conditions) =>growing conditions and harvest time will significantly affect hop aroma. (this can't be any secret to the farmers!) While on the subject, ethanol extraction will significantly affect the GLC analysis, but CO2 extraction or pelletising will not. I know a lot of these journals are difficult to get hold of. I think we'll see them becoming more widely available on the web. MBAA (www.mbaa.com) have plans to do this, I think. The IOB are expanding their website, as are John Haas. This should make things much easier for people to see all this stuff first-hand (and to harass the hop growers!). I'm harassing the Technical Director of Haas about this right now (I don't necessarily expect any answers though). ***** George De Piro says: >Just a quick note to let Andy Walsh know that I hate him. >I have 4 Tettnang vines in my first year hop garden, and they're doing really >well. What the heck should I call them now? Yeah? Well not as much as I hate you George! You're lucky you're not any closer or I'd give those Styrian Fuggnangs (Teggles?) of yours some different growing conditions (somewhere with a little less sunlight)! Andy. Return to table of contents
Date: Mon, 18 Aug 1997 10:02:53 +0500 From: "Keith Royster" <keith at ays.net> Subject: RE: Sankey fermenters Rick Seibt <rseibt at apk.net> and BBrowne at golder.com (Barry Browne) discuss Fermentors for 10+ gallon batches Well, I just finished using my first sankey as a fermenter and I loved it. Rick and Barry seem to have used theirs as a closed fermentor, like a glass carboy while mine I cut open and used in more of an open fermentation method. Here's how I built and used mine: Turn the sankey upside down so the stem hole is pointing down, and cut the upper part off (what was the bottom) using a 4" disc grinder so that a standard stock pot lid will cover the hole. Now, shove a #11 drilled rubber stopper up into the stem hole good and tight. I had to use a hammer to get it in good. Then cut a 2' piece of 3/8" copper tubing into two pieces, one about 4" or 5" long and reconnect them using a copper elbow and some solder. You should have a very tall and skinny looking copper "L". Shove the short end of the copper tube into the drilled hole of the rubber stopper and carefully bend the long end to that it curves up and out of one of the handles of the Sankey. Now connect the valve of your choice to the end of the tube sticking out from the keg. The tube in the keg should protrude up above the rubber stopper about an inch so that the yeast can settle around it without getting siphoned into the secondary. > Activity is tough to judge, you can only go by the bubbling > of the fermentation lock (or lack thereof). Of the the pros for open fermantation in a Sankey, the one drawback is that you can't let it sit it there forever. I am essentially doing an open fermentation in my keg and am thus relying on the positive pressure of fermentation CO2 to keep nasties from slipping in under my lid. Once active fermentation slows or stops it is time to transfer to a closed secondary. I transfered my first batch after only 3 days in the primary once I saw the foamy head collapse back into the beer. > The #11 stopper fits, but because of the notch in the top > of the keg, you need to make sure its snugly in there. Like I said, I had to hammer mine in there good. But there's no worry of it coming out because when righted the entire keg is sitting right on the rubber stopper. > Cleaning can be a bitch. I soak w/tsp or dishwasher detergent asap > after racking or you get a yeast ring like I got. I plan on using > NaOH to get rid of it as soon as I find some. I found mine fairly easy to clean with soap and water as long as I didn't let anything dry too long. My only worry is the seam at the bottom between the rubber stopper and the keg seems like a great place for nasties to hide. > To inspect the inside of the keg, I use a night light (w/o > shade, just bare bulb), attached to an extension cord, and > lower it into the keg and then use a telescopic mirror (Sears > tool section - like a dental mirror) and use the mirror to > inspect the keg. IT WORKS. Just make sure the keg is dry > and I also plug into an GFCI outlet to be safe otherwise > electrocution is possible. > Overall the work load is increased, but the results are > worth it. IMO Sounds like a lot of work! IMHO, I'd cut a whole in the bottom big enough to stick your face in, turn it over, and call it an open fermenter. I had mine cleaned up inside of 15 minutes, no light bulbs or mirrors needed ;) Cheers!

Date: Mon, 18 Aug 1997 09:28:47 -0600 (MDT) From: Ian Smith <rela!isrs at netcom.com> Subject: Taste improvements due to filtering. I talked to one of our local brewers in Boulder, Colorado this weekend and he suggested using a 3-5 micron filter to filter beer and give it a "clean" or "crisp" non-homebrewed taste. Apparently unfiltered beer has a lot of suspended particles that obscure or "clog" (technical term) your taste buds and this masks the hop and malt taste in the beer. Does anyone have any experience with filtering and it's effect on beer taste ? If so could you forward the details of the filter size, type, cost etc. to me or the HBD ? Also how do you keep the filter sanitized ? Cheers Ian Smith isrs at rela.uucp.netcom.com Return to table of contents
Date: Mon, 18 Aug 1997 13:24:15 -0400 From: "Lee Carpenter" <leec at redrose.net> Subject: Budweiser Beer School Stir Doctors, First of all, let me make it clear that I STRONGLY dislike Annheiser-Busch due to their Walmart-like business practices. I will never purchase a product brewed by them again. That said, I must say that I also attended the Bud beer school when the mobile version came to Lancaster, Pa. Our instructor was the assistant brewer from the Merrimack, NH facility, where most of the specialty items are made. To my surprise the presentation was totally devoid of marketing hype and focused only on the hard-core facts of brewing. He answered the many questions, some fairly sarcastic ones included, honestly, and from what I could tell, accurately. The only sign that this was the new "sour grapes" A-B, was a cheesy display by the exit that asked people to "Guess where these beers are made". The display housed a Sam Adams and a Stoudt's brew among others. I took my certificate, bottle opener, and several other trinket type gifts and left without feeling that I had wasted two hours of my life. The price was certainly right (free), and I actually learned a few things. I'll still never buy an A-B product again, but this was definitely an interesting two hours. Lee C.

Thanks to their spam filters, my e-dress is black listed, due to my carrier. I guess my only recourse (other than getting on the Net) is to panhandle 'bootleg' copies of MLD from my fellow HBDers. How sad. You would think that since SPAM is unsolicited commercial e-mail (uce), they would have filters that could differentiate that from legitamite, established, e-dresses,such as my own. I can't even contact the MLD janitor, because that e-dress is filtered also. If anyone can plead my case to him on my behalf, it would be appreciated. Sorry for the wasted band-width, now back to botulism, malta, and insulting others' beer tastes. :-) I'm only kidding. HBD has been a great source of info, and even comic relief.

Date: Mon, 18 Aug 1997 11:43:32 -0600 (MDT) From: Ian Smith <rela!isrs at netcom.com> Subject: When to pick hops ? Avoiding the "grassy" smell ? Some time ago I asked the question about when to pick hops (how do you know when they are ripe ?) and also how to avoid the "grassy smell" associated with home grown hops. Here are the responses: (If any one has additional info please e-mail me). Mike Allred suggested: You should pick the hops when they start to feel 'paperish'. If they 'feel' green and alive, they are not ready. Try drying them as low as you can in the dehydrator. I set mine for 120 deg and it takes about a day to dry them. They are done when you can snap the inner stem by bending them with your fingers. The grassy smell should not be very strong and it goes away if they are fully dried in a few days. Lee Carpenter said: Two things that I was told to remember: 1) The hops will get smaller as the season goes on. Don't let them on the vine waiting for them to match the size of the first picking. 2) Hops are not ready for picking if, when you squeeze them, they feel cool. It sounds dopey, but I found it to be true. And David Burley suggested: Grassy smelling hops ( if I am imagining it correctly) I'm guessing may be due to a "silage" smell and perhaps explains why the professionals treat their green hops with sulfur dioxide to prevent spoilage while drying. Try getting a sulfur candle from your HB store or buying sulfur at the drugstore and burning that so the vapor passes through the clusters before they are dried. I have also smelled hops that are too dry when picked and they do have a sort of dried grassy smell. To test for correct dryness, place a small cheesecloth bag containing a weighed amount of hops in the drier with the rest of the hops and weigh it every 12 hours or so. When you get a fairly steady weight then the hops are as dry as they will get with your method. Hops will lose about 80% of their picked weight.

I have one >>puzzling problem. I made my second ale >>a couple of weeks ago. When I check the SG it seems to be rising, not >>falling. It started out at about >>1100, and is now 1300. >>What now? >>Evan, This rise in specific gravity is caused by yeast regurgitation. You see, the yeast could not properly digest the sugars and thus expelled them causing the rise. This is usually caused by an improper yeast to malt combination. For instance, using a German Wheat malt with an American Ale yeast. Seriously, I can't say for sure because of your numbers and other information is missing. I would assume you are almost done fermenting and the numbers are actually 1.010 to 1.013. This rise could be caused by temperature differences when reading the hydrometer (read at 60 degrees F). Check the calibration of your hydrometer by reading water only at 60 degrees. Should be 1.000. Where there bubbles stuck to your hydrometer while reading that bubbly beer. Spin the hydrometer while dropping it into your test vessel. Another reason could be that your wart/beer may have layers of differing gravity depending upon the depth of that the sample was taken.

I agree with Rob's original idea. I think that people who get lower efficiencies should concentrate on sparging for close to an hour, and keeping their grain temp near 170F during that time. When I can do this, I get higher efficiencies in my system. But sankey kegs need good insulation during the sparge. John Gilman mentioned stopping the sparge once or twice and stirring to increase extraction. I will probably try this next time I brew and see what happens. Makes sense, and would probably allow you to sparge a little faster as well. - Bryan gros at bigfoot.com Oakland, CA Return to table of contents

Well I have received a response to my email from John Haas: My original query was... "From the John Haas website: >Tettnanger is an old aroma variety originating in the >Tettnang area around Lake Constance in Southern Germany. >Selection of Tettnanger rootstocks in Germany resulted in >two different rootstocks now available to U.S. growers. >Each produces hops with distinct analytical data. One is >more like the German grown Tettnanger than the other. Analytical >data in this brochure are for the rootstock most widely grown >in the U.S.A. So which is more true to type, the most common rootstock or the less common? Which appeared first, and how do I know if I am buying the true to type variety if they are both called US Tettnanger? They can't both be Tettnanger, can they? And if not, what exactly is the other one?" The response was: "Dear Mr. Walsh: I am responding to your 13-Aug-97 E-Mail re the above topic. The commercial US Tettnanger rootstock came from the US Department of Agricullture, Corvallis, Oregon hop germplasm collection. The Tettnanger rootstock in that collection came from Germany. Although the Haas brochure says two Tettnanger-type rootstocks are available to US growers, essentially only one rootstock is grown commercially in the US, the one described in the brochure as most widely- grown ie the one with the analytical profile described in the brochure. The US Tettnanger described in the brochure has an analytical profile more similar to UK Fuggle than to German Tettnanger. Therefore, if you buy US Tettnanger hops, you will receive the type described in the brochure. If you want a Tettnanger with analytical profile similar to the German Tettnanger, you will need to buy from Germany. Please feel free to contact me again if you need more information. Yours sincerely, <name deleted>, Vice-President / Technical Director, John I . Haas, Inc." (I have deleted his name as I intend to pursue the matter further, and would request that readers not harass the man until I have the information I desire) Notice I make no mention of Fuggle in my question. He stops short of saying that US Tettnanger is Fuggle, but the inference is that Colin Green is correct. ie. all commercially available US Tettnanger is Fuggle. The mysterious second rootstock *is* Tettnanger but not grown commercially (yet). (I wonder why Haas ever obtained a second rootstock?) Brewing Techniques had an article on US hops at the end of 96 (Vol. 4, No. 6 "Hops in America: A 20-Year Overview", Ing. Gerard W. Ch. Lemmens - I don't have it handy). I was amazed to read under US Tettnang that the authors said it tested closely to German Tettnanger except for low farnesene levels. What nonsense! It tests closely but it doesn't? (sorry I can't provide quotes - I'm sure many of you have this issue anyway). Stay tuned... Andy. Return to table of contents

I would like to tackle a few lager type brews this winter. Any help, suggestions or guidlines? I enjoy Sam Adams lager and would like a recipe for that. I also likew Marzen-Fest brews and would like to try. Any recipes would be very helpful. Can anyone reccomend good recipe books? What about the various brewing Magazines? Thanks in advance.

"...and cant safely do so with propane because of the fumes..." There is no difference in the "fumes" of Propane vs. Natural Gas. Both are commonly used for indoors applications. The problem is oxygen depletion, and it will happen with both, so make sure your room is adequately ventilated. Depending on where you live, your sources, etc. you will probably find that Natural Gas is the least expensive of the three per BTU. - -- Darrell Garton Montrose, CO Return to table of contents

I recently brewed raising my mash-out temp 7 degrees to 176 after reading this thread. Changed nothing else, and realized the same %87 efficiency I've had for the last 5 brews. Bummer. Looks like %87 is the best I can do with my brewery. Although I'm not complaining in the least. Just though this thread gave me someting new to try. On another note. I'm using the "wet towel" technique to lower the fermentation temp (wet towels in my spare shower with the drain stopped up.. my wife is a saint!). Thanks to all who've urged me to try this technique. We'll know in 3 weeks whether it works. Question: Does this technique work for lowering temps below 55 deg? I pored over my notes from the winter and realized that my brewery temps are about 56 in January - February 15. If I lower them an extra 7 degrees using this technique, I can just barely do a lager. As it is now, I just do one lager in February (with lots of fanfare and tons of sacrifices to the Carlsburg beer-gods). If the "wet towel" technique works for lower temps, then I can do 3 outstanding lagers instead of only 1.... Anybody have good results at low temps using the "wet towel" technique? Or is this just a >60 degree phenom. - Mike in Chicago Return to table of contents

I'm sorry this has almost nothing to do even with mead or cider, let alone beer. It is a meta-message about how we beer/mead/cider folk communicate. -rcd] Paul Haaf wrote in the last HBD about having difficulty subscribing to the Mead-Lover's Digest. The problem, in brief, is that there are domains which are often sources of "spam" (junk-email) accounts...so they are blocked upstream of talisman.com (which hosts the mead and cider digests). Some (the cyberpromo/savetrees cesspool; owlsnest) are obvious--there's no reason to let them through. But there are other domains which host both legit users and too many spammers to ignore (including one-shot attackers). Some of these are blocked, and it causes problems because the legit users can't get email through to various places they might want. (The mail doesn't bounce; it is rejected outright, upstream of me. I never see it; I only find out by some out-of-band approach like Paul's plea to the HBD.) I won't just un-block all the spam domains...I can't, because my modems and machines are too busy to put up with some of the attacks I've gotten. If you try to subscribe to MLD or CD and get a spam-block rejection, I'd say (a) think about your choice of ISP, their policies, and in particular whether they make accounts available in a way that encourages the one-shot attackers. Sometimes getting a cheap account isn't worth the bargain. (b) Talk to your ISP about their policies. If I find out that an ISP has taken steps to clean up its act, I'll work to get it unblocked. (c) Find a way to get through and I'll try to accommodate you with an exception.

Do you all have any combinations you particularly >like? I'd love to hear about them. Personally, I like using Chinook for bittering American Pale, IPA, and Browns. Gives a nice robust bitterness with some flavor components coming through even after an hour in the kettle. I'm still experimenting, but my favorite combination so far adds both Cascade and Goldings in various measures and at various times between 30 and 15 minutes before the end of the boil for flavor, with Cascades at kettle off and/or dry-hopped. Sometimes I throw some EKG or Willamette in the secondary as well for that added aromatic touch. Centennial seems to work well for me, especially in combination with Chinook for bittering-- it seems a bit smoother and less obviously grapefruity. Also, I haven't brewed with 'em yet, but from what I've tasted of commercial beer that has used Columbus, I look forward to trying those for bittering. - -- Joel Plutchak (plutchak at uiuc.edu) Research Programmer, Department of Atmospheric Sciences University of Illinois at Urbana-Champaign Return to table of contents

Date: Tue, 19 Aug 1997 10:20:42 -0700 From: Tim Plummer <plummer at brick.purchase.edu> Subject: Neophyte anecdote Hello homebrewers, After waiting several months for the summer's heat to abate, last night I brewed my first batch of the season--my second season. 4 gallons of an ordinary bitter which will, hopefully, be ready for opening day of football season. Everything was going great; all the procedures were coming back to me as if I hadn't taken a break from brewing at all. Until... I put my lid on my plastic fermenter, then inserted the airlock into the gasket. ...plunk... In fell the gasket into my precious wort. I had forgotten one simple procedure: put the airlock into the lid BEFORE you affix the lid to the fermenter. My only option was to scrub down my right arm, plunge it into my brew, and retrieve the gasket. Time will tell if any damage has been done. Here are the lessons I've learned from this little happening, which I would like to pass on to others who may be resuming their brewing practices after a summer hiatus. 1)thoroughly review your procedures, it could be something small that leads to your 'unbrewing.' 2)have a spare rubber gasket for your lid Regardless of my gaff, it was great to have the smells and flavors of fresh brew in my home again. Brewing season has arrived, and not a minute too soon! Hoppy brewing, Tim Plummer (Port Chester, NY) plummer at brick.purchase.edu Return to table of contents
