---------------------------------------------------------------------- Date: Fri, 18 Mar 94 12:33:11 EST From: Keith MacNeal 18-Mar-1994 1222 <macneal at pate.enet.dec.com> Subject: Hop utilization Here were some thoughts on hop utilization and wort gravity that I sent to Norm. The discussion is getting lively so I thought I'd chime in as well. My response to Norm was similar to the post by Mark Garetz on boil volume, but looking at it from a slightly different angle: Norm, I saw your post about increased bitterness and an apparent relationship to full boils. Keep in mind that not only has the SG of the wort changed by going to full boil, but also the volume of the wort has changed. Chemically/ thermodynamically speaking, it makes sense that more bitterness (aka iso-alpha acids) can be extracted in a greater volume -- much the same way you can dissolve more sugar into a pot of coffee than you can in a mug of coffee. That's not to say that SG doesn't have an effect. To me it seems it should, but I'm too busy playing with other things in my brewing to worry about this one as yet.

You have doubled your batch size from 5 gallons to 10 gallons, therefore you have appropriately doubled your hops. The extract brewer is adding enough hops to the kettle to hop 5 gallons while only boiling 2 or 3 gallons. He/she is not doubling the batch size. Keith MacNeal Digital Equipment Corp.

Date: Fri, 18 Mar 94 12:50 EST From: <GNT_TOX_%ALLOY.BITNET at PUCC.PRINCETON.EDU> Subject: IBUs (again!) Well, I was rechecking my IBU equations for my wheat beer. According to Papazian, a weizenbier is supposed to have between 8-14 IBU. So, I did the following boil: 0.70 oz. of Northern Brewers (6.8%) for 60 minutes and 1 oz. of Hallertauer (1.5%) for 15 minutes. I assumed a 20% utilization since I am doing the concentrated/dilute in the fermentor method. My numbers came pretty close. I was at 14-15. Wells I loaded up SUDSW and plugged the numbers in the IBU calculator, and came up with 31.6 IBUs! Wow! Now, who's off here? Return to table of contents
Date: Fri, 18 Mar 94 09:51:48 PST From: hpfcla.fc.hp.com!relay.hp.com!daver!nexgen!bart (Bart Thielges) Subject: keg pressure William Nichols relates problems with force carbonation of kegs. I don't have exact answers for proper PSIs, but I do have the following advice : "Store high, Serve low" That is, you need to lower the pressure for serving. Afterwards, the keg should be pumped up to preserve carbonation. I've found that 5 PSI is plenty high for serving, but is too low for storage. This isn't a problem if you use the keg for a party. Its more of a problem if you want to have a pint after dinner each evening. I base this advice on the behavior of my Cornelius keg. My theory is that these kegs were meant to dispense soda syrup and thus were not designed to minimize CO2 wrenching turbulence. If you've ever seen the inside of a Sankey keg, you will notice that the take up tube is one inch or so in diameter. This is huge compared to the Corny's narrow dip tube. - ------------------------ On a completley different topic : As I was preparing to bottle my last two batches, I decided that it was time again to disassemble and clean the faucet on my bottling bucket. It is a little tricky to take that faucet apart, but it does indeed disassemble into five pieces. I was shocked to find a blob of old beer stuck to the inside of one piece. There was something growing on it that definately was not Wyeast German Ale! For now on, I'm going to inspect that thing EVERY TIME !

Well, I won't try to convince you, since I often do single-stage ferments myself, but I will give you a reason for a 2-stage fermentation: your beer will end up much clearer and have much less sediment in the bottom of the bottles or your keg. There are arguments as to whether leaving the yeast on the trub affects the taste of the finished beer, but I'll let others make those arguments. :-) rprice at cbmse.nrl.navy.mil replies to a query about banana esters: > Typically the banana odor you describe is amyl acetate, and not often > among the alcoholic beverage/Fermentation products you find. but then lists isoamyl acetate among other common fermentation products. Maybe you meant to say "and *often* among...", although from my experience it is not as common as other esters like diacetyl and various sulfur compounds. The canonical example of yeast which exhibits high amyl acetate production is Chimay trappist yeast (or the similar WYeast Belgian strain). In some styles, like trappist ales, some banana ester is a desired characteristic. arf at mcs.com (Jack Schmidling) writes: > The copper pipe manifold is an alternative but is grossly complicated and > difficult to build compared to the em and I don't know of any commercially > available nor why one would want one. Not to argue with you, Jack :-), but I wouldn't call a copper manifold setup "grossly complicated and difficult to build". In actual operation is may be no better than an em, but it takes 30 minutes with a hacksaw or tubing cutter to build a manifold. And a manifold may not be commercially available, but I do know of a commercial brewery that uses one -- the New Belgium Brewery uses a copper manifold in their several- hundred-bbl mash tun. It's identical to the one I use at home in every respect except for size. BTW, if anyone wants plans for a copper lauter manifold, or an easymasher, or any other schemes presented in HBD, grab the all_grain_equipment file from sierra.stanford.edu. Then decide what's easiest for you. - -- Jeff Benjamin benji at hpfcla.fc.hp.com Hewlett Packard Co. Fort Collins, Colorado "Midnight shakes the memory as a madman shakes a dead geranium." - T.S.

I can't think of a single > advantage other than potentially faster lautering with a false bottom and > that has questionable value in homebrewing. In a RIMS, a false bottom in the mash is necessary because it provides an open area for flow large enough to allow reasonable pumping rates. My RIMS false bottom is simple and inexpensive. I use a 16-inch diameter pizza pan that is coated with a no-stick material. These pans may be bought perforated with several hundred half-inch diameter holes that allow pizza crust to brown better. I covered the top of the pan with stainless steel screening and threaded it on with fishing line. The false bottom fits nicely at the bottom of my sawed-off pony keg RIMS mash tun with a relatively small ullage space under the pan. It stays in place during the mash and it's easily removed for cleaning afterwards. - -- Jeff Berton, Aeropropulsion Analysis Office, NASA Lewis Research Center jeff344 at voodoo.lerc.nasa.gov Return to table of contents

Date: Fri, 18 Mar 94 13:43:03 -0600 From: gjfix at utamat.uta.edu (George J Fix) Subject: A new brewery for Houston It gives me pleasure to announce the formation of St. Arnolds Brewing Company of Houston, which will become that city's first micro. St.Arnolds will be a 60 bbl. operation, and will feature state of the art equipment custom designed by Gary Bauer. Gary has over 50 commercial systems in currrent operation, but this one IMHO is his masterpiece. Brock Wagner, a noted Houston homebrewer, will be the brewer, and I am serving as the technical consultant for the project. Installation of the equipment is scheduled to begin on April 2, and the first brew will be done on April 9. St. Arnolds' initial beer will be an amber ale. Test brews using this formulation have done extremely well in blind consumer preference polls, so everyone involved is "anxiously optimistic". The beer will be available on draft in Houston at beer oriented watering holes (e.g., The Gingerman). A bottling line is currently under construction, and is scheduled for delivery in the middle of May. The bottled version will be widely distributed, although initially only in Texas. Those in the Houston area who have never seen a "first brew" done on a new system are encouraged to tour the facility on the 9th. More info can be obtained from the brewery (713-686-9494).

Date: Fri, 18 Mar 1994 13:15:21 -0800 (PST) From: Eric Wade <ericwade at CLASS.ORG> Subject: Glass airlocks, canning wort Let me second Mike Dix request for sources of glass airlocks, either SF Bay Area or nationwide mailorder. Thanks to all for the responses both privately and to the list on canning of wort to save for yeast starter. It looks like many of you are successfully canning using just the hot water method (not pressure canning). The big concern in canning pH neutral foodstuffs is botulism. I remember a couple of incidents of commercially canned mushrooms and vichyssoise around 1970 that knocked a few people off. Why would anyone use canned mushrooms anyway?? But I digress. Botulin spores are not killed by the heat in non-pressure canning and, unfortunately botulism does not produce any off odors or appearances. Generally you don't know about it until it is too late. Nobody posted that they got botulism poisoning from improperly canned wort, but how do we know they haven't croaked in their basement brewery? But seriously, is their someone out there in HBD land with enough food science expertise to tell us if wort is acidic enough to keep botulism at bay without pressure canning? =Eric Return to table of contents
Date: Fri, 18 Mar 1994 13:54:02 -0800 From: belew at netcom.com (Jonathan Peakall) Subject: Kegging I have been brewing with a couple of friends for about 8 years, in ever increasing quantities. We have now reached the point of brewing a 100 gal. batch, and have finally obtained some firestone (I think that's what they're called?) kegs to ease the bottling hassle. I read the excellent article on kegging in the archives at Stanford, but still have a few questions. First, does anyone know a good place to purchase fittings and so on for the kegs in the San Francisco Bay Area? What about places to test and fill your co2 tanks? Can anyone tell me the name of a good book on kegging, or direct me to a good source of materials? I have always been pretty isolated in my brewing, and was amazed when I read some of the old articles. It seems most people who subscribe to the HBD are pretty scientific about brewing. It makes me feel positivly hap- hazard. I weigh my ingredients with a broomhandle balanced on a ruler, and only use the hydrometer once, just before pitching the yeast. After the secondary fermentation slows down, I rack off the brew from the carboys, add a little corn sugar an bottle. Thing is, the beer has always been good! Anyway, it is great to be in contact with other brewers. Any advice or information is welcome. Thanks! Return to table of contents

Dextrins don't add any substantial sweetness to your beer. The addition of dextrins increases the viscosity and imparts a certain smoothness. The addition od dextrins to your beer does decrease the perceived hop bitterness. Your reasoning above seems to be based on the use of a low temperature mash - that is one favoring beta amylase activity over alpha amylase enzyme activity. If you conduct your mash at temperatures that discourage beta amaylase activity, you will not break down all of your dextrins to fermentable sugars. Some guys wrote an article in Zymurgy awhile back that touted benefits from adding darker grains to the mash at 'mash-out', but I believe the point was the preservation of melanoidins for the enhancement of "smoothness" and rounder flavors. <s12int::l375bbk at god.bel.alcatel.be> writes: > Lakefront Brewery, Milwaukee, WI - This is a low budget brewpub.

I guess I'd refer to the Klisch operation more as a brewery on a shoestring, although I believe they have financed several expansions since they opened. The last time I was at Lakefront, they were not a brewpub. Have Russ and Jim added a bar? If their performance to date is an indication, I'd say that they have developed a track record.

Date: Fri, 18 Mar 1994 15:39:04 -0800 From: bguerin at orincon.com (Bob Guerin) Subject: Hop Utilization Tests I was pleased to see the results of the "wort gravity" test in HBD #1375 (Thanks, Glenn!). The results, though anecdotal, seems to indicate that the wort gravity *does* affect the utilization in the boil. Something interesting about those results: the 42% utilization for the low gravity wort is much higher than the 30% maximum listed by Rager. Also, the reduction in utilization from the lower to the higher gravity wort is also much higher than in Rager's formula (which predicts a factor of 1.18 instead of the 2.1 seen in this case). I would like to propose the following test, one to check out the "hopping rate" theory supported by Mark Garetz. At the start of a boil, draw off a small quantity of wort into a separate pan. Add the same quantity of hops to both pans. Boil both for the same amount of time. Add water to the smaller wort to bring it to the same volume as the original. Take samples of both, and measure the iso-alpha acids. Glenn - are you interested in trying this? Bob Guerin (bguerin at orincon.com) Return to table of contents

Oh, the pipe manifold isn't that hard to make. I just wrapped some copper around my soda keg and soldered a dog-leg on the end to meet up with the compression fitting soldered through the side of the keg. I have been very happy with the performance (Ultra fast lauters, 100% extract yields). I would have done something like the EM, except that I had the copper and I didn't have the SS screen. Also, I used a similar arrangement for the kettle but with a ring that fit just above the dome against the side of the keg. That way all trub and hop particulates (I use pellets) sit in the dome and I rack off clear wort. The dome holds less than 2 qts so wort loss is minimal in a 10 gal batch. As Jack said, with the EM or a ring, one can bottom heat the mash without worrying about scorching. I can't imaging spending the money on a false bottom arrangement of any sort after using the ring (or an EM if Ihad some spare screen laying around) - -- Larry Barello larryba at polstra.com 10034 NE 22nd ST (206) 454-6958 Bellevue, WA. 98004 Return to table of contents
Date: Sat, 19 Mar 94 00:04:33 EST From: katanka at aol.com Subject: Re:Dry Malt Priming I also have tried the dry malt priming trick as per Papazian's book. Both with corn sugar and DME. Carbonation for these batches seemed poor at best. Then on a whim, I tried a different method. Us8ng the information on krausening (Papazian's Book) I created my primer by making a "Simple Syrup" with Dry Malt Extract. This simply put, is a mixture of 2 parts water and 1 part extract or sugar. Example: I use either 3 cups water to 1.5 cups DME or 2 cups water and 1 cup corn sugar. Then I boil the mixture for 10 minutes and cool quickly (cover with cheese cloth or paper towel and set in freezer) when warm, I dump the primer into the bottling bucket and siphon into it. I believe this creates a better primer because the primer is now a liquid which will mix more freely with the beer. Also, the sugars are already in solution which makes them more available to the yeasties! The resultant carbonation seems much better (as well as head retention(?!?)) you can adjust the amount as needed, but keep the 2 to 1 ratio. Katanka Return to table of contents

I consider myself an advanced brewer--six years of brewing, over ninety batches, mostly all-grain--and I have an abiding interest in some of the finer points of the craft. however, I feel that the preoccupation with some rather obscure points on the digest IS eating up bandwidth; my space bar is quickly wearing out. Perhaps the interested parties could start their own digest--the "HUD" (Hop Utilization Digest) or the "BB-BBD" (Bad Bottlecapper-Broken bottle Digest), or maybe, as I have (seriously) actually read in one post, there would be room in the Alt.Beer space in the Usenet. I enjoy reading the HBD each day--picking up new recipe ideas, innovations for the mash process, and replying to those in need of help.

I recycle the complete mash volume and more before the wort clears. Even with that it isn't "bright". On the otherhand my Zap-Pap always yields clear wort with about a gallon of recycling. | __|___|___| This is my mainfold geometry. | | | | Do any others share this experience? Any explanations? Conjecture? Jokes? Let me also add that I am greatly enjoying the Hop utilization thread.

Date: Sat, 19 Mar 94 12:33:58 From: Christopher Alan Strickland <beach!chris at cocoa12.ksc.nasa.gov> Subject: Blackberry Stout Just wanted some opinions. I made the blackberry stout with 60 oz of frozen blackberries. My OG was 1.061, after 3 days I racked with an SG of 1.027. After 5 days the SG was still 1.027 so I bottled. It's 12 days latter and the beer tastes a little sour (not going bad sour, just sour). I expected with the high FG that it'd be a little sweet (though I prefer dry beers). Am I just being too impatient, and need to let it age a while longer, or could it be that the frozen black berries could have been piced before ripening causing the sour taste? - -- Chris Strickland Internet: beach!chris at cocoa12.ksc.nasa.gov Return to table of contents
Date: Sat, 19 Mar 1994 13:04:52 -0500 From: dd596 at cleveland.Freenet.Edu (Marc L. Goldfarb) Subject: Thermometer calibration/hop rhizome sources/beer festival/etc Hi All: Some of these comments may be out of date, but I am so far behind in my reading that I just finished #1363. First of all, regarding locations of brewpubs in various city, i mean cities, the best source of that info is to call any homebrew supply store in the city in question and ask them. I travel quite a bit, and the first call in any city upon arrival is that one. It *NEVER* fails. Now on to important stuff. It has recently come to my attention that my $5 dairy thermometer may not be the most accurate measuring device available. What a shock. Anyway, I boiled some water this morning and the thermometer read 207 degrees. Cleveland is at about 600 ft. above S.L., so I don't think that a conversion is necessary. My question for any of you scientists out there is: will the error of 5 degrees be linear throughout the range of the thermometer? If not, how do I adjust for the error? Or don't I? Next on the hit parade, I would like to thank all those who responded to my request for rhizome sources. BOTH responses were very helpful. As promised, here is the info. 1) The Malt Shop in Cascade, Wisconsin. 800-235-0026. I spoke with Don this morning and he was very helpful. They have a deal going right now. Order 3 rhizomes and Beach's book on growing hops and get a $2.00 discount. 2) Freshops in Philomath, OR. 503-929-2736. 3) American Brewmaster in Raleigh, N.C. 919-850-0095. The usual disclaimers apply. And finally, I am looking for any info on beer festivals around the country. Homebrew or commercial. I would especially like to be able to contact the organizers of these events. Any info via e-mail would be greatly appreciated. Hoppy brewing. Now back to the last 3 weeks of the digest.

Date: Sat, 19 Mar 94 13:43 CST From: arf at mcs.com (Jack Schmidling) Subject: COPPER MANIFOLDS >From: "Thomas Kavanagh, Curator" <TKAVANAG at ucs.indiana.edu> >I do not wish to disparage Jack's products--I lust after a Malt Mill(tm)--but I would like to say a few words in favor of my version of the copper manifold. Nor do I wish to disparage anything that works and was fun to build. However, you have done little in your response to dispel the notion, that a CM is more complicated and difficult to make than an em. > I did not need to dedicate my $50+ 5 gallon SS mash tun pot only to brewing, I can't argue a philisophical point other than to say that people have made easy mashers as you suggested with a long piece of tubing coming up and out of the kettle to preclude drilling a hole in the kettle but I think many brewers have no problem dedicating brewing equipment to brewing. This is especially true when getting beyond the 5 gallon kettle. I can't think of too many other uses for my 10 and 16 gallon kettles other than fermenting wine in it and the em works great to draw off the fermented juice and leave the pulp behind. Furthermore, the em strainer assembly can be removed leaving only the spigot which won't interfere with boiling spagetti. > nor did I need to find a jobber who could cut a hole in a SS pot. Having done what you did, I would be very surprised if you could not drill a 3/8" hole without outside help. Now we get to the real question, what is the advantage of the CM? It seems a bit like RIMS, once you get beyond the fun of building, using and talking about it, it offers no advantage over simpler methods. >From: Jim Busch <busch at daacdev1.stx.com> >> J.S. Actually, I do not know of any way to deal with the scorching problem with a false bottom. It almost precludes mashing in the same kettle. >Broken record time?? Your last statement is the real issue here. Sizable breweries who want a flexable mash schedule do not mash in the same vessel as they lauter in. They would if that had a MICROMASHER. Not sure who is playing the broken record nor can I connect your statement with the one of mine you cited. What "sizable breweries" and advanced homebrewers do in this case is not relevant to the discussion. The point I made was that one loses the option of mashing or boiling in the lauter tun if it is equipped with a false bottom. For the homebrewer with one kettle or the low budget extract pub brewer, the em offers an inexpensive means of making all grain beer in a single vessel. > Usually the mash tun is also the brew kettle. This necessitates the very messy and time consuming step of transferring the mash to the lauter tun which, with an em, requires only the opening of a valve because the mash tun is the lauter tun. >RIMS systems avoid this, and make use of a false bottom just fine. Hardly the low budget approach I was addressing. Nor does it preclude using an em in a RIMS system. >I can also lauter weizens and Wit beers with ease. Do you know of anyone having problems doing that with an em? I guess I should say EM, as I can't be responsible for what others make. >From: Allen Ford <allen at darwin.sfbr.org> > 1)The *dead space* under the false bottom (known to brewers as foundation) allows for easy addition of heat to the mash for temperature correction or for step mashing. The scorching problems can be avoided by recirculating while applying heat. I suppose with enough rhetoric, any fault can be turned into a "feature" but this is the first time I have heard such claims for the space under a false bottom. Contrary to what you claim, it CREATES problems when adding heat and makes scorching very difficult to control. Steam and boiling water get trapped under it and there is no way to redistribute the heat other than recirculating the steaming water. With an em, you simply stir occassionally to redistribute the heat. > 2)Stuck mashes are not a problem (provided the grain is milled well) because of the large drainage surface area. If a mash sticks, it is simple to re-float the grain bed by reversing the flow and pumping into the bottom of the mash tun. Simple? I have made batches using malt purposely ground to flour in a Corona without having them stick. I have NEVER had a stuck mash with an "EM" and don't know anyone who has. > 3)Cleanup is quick and easy. Simply remove the false bottom and hose it off. The EM unscrews and weighs 2 oz. >There is no doubt that the easymasher is cheaper than a well-made false bottom. How does one perform a step mash using the easymasher? Turn on the heat, stir and shut off when at temp. > Can heat be applied to the bottom of the mash tun without scorching the grains that are in contact with the bottom? That's a given. That's not to say you can turn on the burner at full blast and walk away for an hour. But with judicious stiring and attention to what is goin on it is no problem at all. > How does one unstick a stuck mash? Never having had one I can only say what I have done on a what-if basis. One would lift the output hose above the level of the liquid in the kettle and gently blow into it. Sort of what was suggested for the fb but much less hassle. >How large a mash tun will an easymasher drain effectively? The homebrew version works well up to half barrel systems. I have one on 10 and 16 gallon vessels and on a 1 gal pilot system. The yields and functionality are comparable on all three. The newly announced MICROMASHER will handle anything likely to be found in a Micro or pub. Now, for the record, George Fix recently ran a test on what I call the COMPLETE EASYMASHER, i.e. an EM installed in an 8 gal ceramic on steel kettle. He corroborated most everything I have said about it and the only negative comment was the fact that it did not drain/lauter as fast as his $300 DME fb. This may be the nature of the beast or may be a result of extenuating circumstances. One of which that can not be overlooked is that he only made a 10 liter batch which is at the low end of what can be done in that very squat kettle. The higher the liquid level, naturally, the greater will be the flow rate. The wide open flow rate could also be limited by the plumbing size and is the reason for the scaled up MICROMASHER. It is my experience with 10 gallon batches that I must always throttle back the flow rate to get the lauter rate I like. After hearing from George, I timed the last batch and it took 1 hr and 12 min to sparge 10 gallons and collect a total of 14 gallons of wort. I think the direction this topic has turned over the two years since introducing the EM is most encouraging. The first year was spent arguing with people who never used it that it works at all and now it seems to be trying to prove that it has truly revolutioniized all grain brewing. js Return to table of contents
Date: Sat, 19 Mar 1994 12:52:20 -0800 (PST) From: Davis <sekearns at ucdavis.edu> Subject: one large beer Is it possible to fill one 2.5 gallon carboy with beer, cork it, and drink it as one large beer. For example, after mixing fermented wort with bottling sugar or dried malt extract, rack half the batch to a 2.5 carboy and bottle the rest? Any thoughts please e-mail. I have a "bud" keg, typical commertial keg. Is there any way to "de-bung" these kegs? Can these kegs be used by home-brewers or only by the beer companies? Thanks for any suggestions.

Date: Sat, 19 Mar 94 23:20:46 PST From: Mark Garetz <mgaretz at hoptech.com> Subject: Mea Culpa Glenn Tinseth's data was very interesting, showing that wort boil gravity may indeed have an effect. I could have sworn that I had data showing no effect all the way up to 1.090 but I can't find it, so maybe it is the result of one-too-many homebrews! :-) Anyway, the paper I referenced only showed results up to 1.050 where it is clear that boil gravity had no effect. Rager may have used this data because his gravity adjustment starts at 1.050 (anybody know?). So the research I was basing my information on does not appear to be extendable to worts with gravities above 1.050. Given Glenn's preliminary results, I am willing to admit that I most likely incorrectly extrapolated the data I had to all wort boil gravities. So even though there is still a significant fermentation effect due to gravity, I am no longer willing to state that boil gravity has no effect, at least for worts above 1.050. One thing I wanted to point out: Glenn was very clear in his post that what he measured was *kettle* utilization so don't jump to conclusions that you should be getting 40% utilization in your finished beer. Fermentation will cut this back down to the normal range of 18-25% (and you can imagine what happens to the high gravity wort that *started* fermentation at 20%). Mark Return to table of contents
