In >your recipe, are your percentages expressing the >ingredients ratio by weight or by extract? In your >experience, which is the preferred method? > [snip] According to Michael J. Lewis in the AOB Classic Series book on Stout, the brewing industry (professionals) formulate by percentages of extract. It is homebrewers that have fudged things and sometimes report recipes in percentage by weight. Without knowing the relative extraction rates among the various types of malts, it is hard to do an accurate conversion from one expression of the recipe to another. (Note that it is probably not fair to assume that if you have an X% rate of extraction on the average, that you extract X% of any particular malt's maximum theoretical extract in a mash. The extraction process is different for different malts and depends on crush, soluble solids, and the various enzyme activities in the various mashes and mixtures of mashes.) Comments anyone?

Date: Mon, 7 Feb 2000 00:41:52 EST From: ThomasM923 at aol.com Subject: Foam space I just purchased a keg to use as a boiler. It has inspired in me such a lust for stainless steel that I am now considering purchasing another one of these kegs for fermenting 10 gallon batches in. This keg is a bit smaller than the usual 15.5 gallon type, having a 13.4 gallon capacity which works out to about 12 gallons usable space. I am wondering if there is enough space in this size keg to contain all the foam in a 10 gallon batch during high krausen? I've read that one needs about 30-40% headspace in a plastic fermenter, however a keg is proportionally wider than a plastic bucket. I am wondering if anyone that uses a keg as an open fermenter can give me an idea what the typical amount of space the foam takes up is. metallically yours, Thomas Murray Return to table of contents

Reminds me of the time my wife and I had an apartment in Hoboken, NJ. Every now and then the landlord would send a guy by to spray roach killer under the cabinets and behind the fridge. We never thought too much about it before, but this time we were the new parents of a baby girl and somewhat concerned about the chemicals the guy was about to put in our apartment. My wife asked him if he thought the chemicals posed a health risk. He said: "Just take a look at me. I been doin' this kind of work for years, and I'm fine." We somewhat reluctantly allowed him to spray, and after a few minutes he was on his way to spray the other apartments. About a half an hour later we heard a knock and when I opened the door we found the same guy standing there. Thinking that he had left something behind, I let him in and shut the door. His eyes widened as he looked around in amazement and said: "Wow! You won't believe this but a coupla minutes ago I was in an apartment that looked exactly like this one.

Rich Rodda asks about a Rheingold recipe. Brewing Techniques has two history articles on their web site, which is still up and running. The first address has a recipe and the second address is good for general background reading: http://brewingtechniques.com/library/backissues/issue2.1/jankowski.html "The Bushwick Pilsners: A Look at Hoppier Days" by Ben Jankowski http://brewingtechniques.com/library/backissues/issue2.3/fix.html "Explorations in Pre-Prohibition American Lagers" by George J.

The smaller guys are pretty certainly a wild strain introduced somewhere during the brewing process. It is quite common for these guys to poduce phenolics in undesireable quantities. * * * * * * * * * * * * * * * * * * * * * * * * Dave forgot the farthing (1/4d and please be sure to notice that the h is not silent). Also note that the 'd' comes from Latin "denarius", "...a Roman silver coin originally equivalent to ten asses but afterwards to eighteen; equivalent to an Attic drachma...". The denarius lives on in 6d nails and in several middle eastern countries which use the "dinar" as their currency. Does this have anything to do with beer? Of course it does. The Bahraini Dinar reproduces on its back a picture of their Monetary Authority building upon which are mounted large replicas of four coins from the acient Dilmun civilization. Clearly visible on one of these coins (on the bank note as well as the building) are two Dilmunites having a beer. They are drinking through straws from a large vessel. Obviously I'm interpreting here but the scene looks very much like other representations of beer drinking from that part of the acient world. The straws were used to get past the unpleasant material which floated on the surface of the beer. Return to table of contents
Date: Mon, 7 Feb 2000 09:09:16 -0500 From: "Robert Bratcher" <rbratcher at advanceautoparts.com> Subject: Thanks Rock Creek Brewing Brewers, Long time lurker, infrequent poster here. At our club's ,Star City Brewers Guild (http://hbd.org/starcity) ,last meeting the monthly "style" was actually a clone attempt of Rock Creek's Black Raven Porter. We were very fortunate to have Jon Esposito, RC's President, attend our meeting with a nice fresh keg of Black Raven to aid in our judging. Due to our club members participation with their clone attempts and, in a really big way, Jon's presence and willingness to answer questions and share knowledge on RC's brewing procedures and recipes, our Febrewary meeting was outstanding. I don't know if Jon reads the HBD, he does have a history of home brewing, but I wanted to get a BIG PUBLIC THANKS out there to him for attending our meeting. I would also like to encourage other clubs to seek out ties to breweries in their neighborhood. As a result of our meeting we hope to work with Rock Creek in the future in developing events, competitions & festivals, and arrange field trips for the club to their facilities. This may not seem like much to many of you but the closest brewery to Roanoke, VA is at least a three hour, or more, drive toward most points of the compass. I even got to meet a fellow HBDer, thanks for coming Drewmeister. Rock Creek Brewing is headquartered in Richmond, VA with brewing facilities located in Raleigh, NC. http://www.rcbrewing.com Check out their web site and try to find some of their brews. Besides the Black Raven, Devil's Elbow IPA is a club favorite while all of their brews are excellent.

The time has come for me to get rid of some equipment. I have a bunch (15?) of pin-lock corny kegs that are unfortunately just taking up space in my basement. The gaskets have been changed and the the insides cleaned. They have been stored for the last 2 or 3 years in a mild iodophor solution (inside, of course). (Is this bad???) I also have 3 (three) 1/2 barrel and 1 (one) 1/4 barrel kegs (Anheuser-type) that I have done nothing with. I originally planned a 2 tier/3 tank system, with perhaps, a decoction "keg", but I have just never had the time to build the system, let alone brew. I live on Long Island, NY and would prefer to not ship. I might be willing to meet people "halfway" with as many cornys/kegs as I can fit in my Volkswagen (I'm sure I could squeeze more in there than you think!). Please respond privately, if interested, with offers. I am extremely flexible. Regards, Mike Otten Return to table of contents
Date: Mon, 7 Feb 2000 09:25:31 -0500 From: "Czerpak, Pete" <Pete.Czerpak at siigroup.com> Subject: conical fermentor angle In HBD #3241, JOe Gibben asks for a conical fermentor bottom angle. I think that 60degrees from horizontal is about the correct angle. This is what is sold for the homebrew version of conical fermentors. The reasoning behind the angle is the closer to horizontal your angles get, the tougher it is for the yeast to slip down the sides of the fermentor when they flock out - making harvest and clarrification tougher. However, as the angle gets closer to vertical, the height of the fermentor obviously gets taller. 60 appears to be the industry balance. Good luck with your welding. Would love to see a picture when its complete. Regards, Pete Czerpak Albany, NY Return to table of contents

At the time I saw it, I wasn't using any finings so I doubt that it is related to the gelatin finings. Interestly, if Steve had paid a bit more attention, he would have noticed that the "fur" was on the same side of all the bottles. I believe that it has to do with some sort of temperature differential in the room where the beer is conditioning. The cure for the "fur" is to simply twist the bottles a bit to dislodge the stuff from the walls of the bottle so that it can fall to the bottom. Anyone care to speculate about the cause??

I have never seen >this before. Is it the gelatin sticking to the sides of the bottles? >The beer is crystal clear and tastes great but I am just a bit stymied >by the stuff hanging on the sides of each and every bottle I've had a similar phenomenon in the past, but the grainy material only speckled the glass on the bottom 1/4 of the bottle. I didn't use gelatin or any other fining agent. The beer was great, so I chalked it up to being small yeast colonies which adhered to the glass. I don't remember which batch it was, but I guess it depends on the strain of yeast used. Waiting to see other responses as I still have reservations on trying gelatin for the first time (and isinglass as well). Dave Burley commented on modernizing brewing language: >Speaking of language, in the >spirit of modernization and in >line with the "modernization" of the >counting system, why don't we >stop using these antiquated terms >like tun, lauter, wort. grist, mash >and the like. Why not reaction chamber, >extraction, fermentable solution, >comminuted reactants, reaction >mixture? These terms are too logical and actually make sense. How shall we keep the neophytes confused? Enzyme reactions? Our sacred work must be protected from those who would defile it! I think we should make up a secret language as like the alchemists did ;-) JPullum127 told us about the dumbest guy in the state: >i just had my new washing machine delivered by the dumbest guy in the state. >i had to write some of his comments cause they are so strange it was funny. After reading this I want to know two things: 1. Which state would that be? (We have our fair share of idiots in NJ) 2. Did you check to make sure he didn't hook up the washing machine to the gas line by mistake? (I've seen people try to make this work.) Return to table of contents

Or maybe the foam stopper doesn't cause a slight increase in head >pressure as you would get from the weight of the column of water in the >S-lock, so there is less CO2 dissolving into that starter? Pat, I think it is likely that your first guess is the correct one. The foam stopper is probably allowing air (oxygen) into the flask which will enable the yeast culture to grow more quickly and probably to a higher density. Another possibility is that there is some sort of contaminant in this flask, especially given the long length of time you've been running these cultures - Not meant to be a slam against your aseptic technique Pat! -Alan Meeker Baltimore, MD Return to table of contents

Date: Mon, 7 Feb 2000 09:52:52 -0500 From: "Alan Meeker" <ameeker at welch.jhu.edu> Subject: microwaves - an actual experiment! This is cool - I tried the experiment. I got a 125 ml smooth-as-silk Pyrex Erlenmeyer flask, washed it well, rinsed the hell out of it w/ distilled water then filled it about 3/4 full and put it in the microwave for 10 minutes which was obviously way too long but I was going to stop it after a few minutes. Unfortunately I forgot about it. the next thing I knew I heard a big "BOOM" from across the room - nearly the entire contents of the flask had explosively evacuated all at once! Wow! (although this probably has a lot to do with the geometry of the flask and may not be as much of a problem for something with a larger opening like a coffee cup). So I refilled the flask, reset, this time for 5:30, then I brought it to /just/ boiling visibly and /carefully/ took it out and /carefully/ lowered the smoothest thermometer I could find into it - it shot up to 103 degC !! Cool! I repeated the experiment a few times and each time the measured temp was between 101 and 103. It is a bit hard to make the measurement as the thermometer does indeed nucleate bubble formation and if the water is too hot the whole thing goes critical. This also happened when I bumped the flask on the microwave getting it out or set it down on the bench too hard. "Kids, don't try this one at home!" Well, I am even more convinced now that superheating is a real phenomenon: The water was distilled lab water so there shouldn't have been enough dissolved solutes in it to account for the rise in boiling point. The thermometer was our good NIST standardized thermometer so I trust the reading. I was careful to submerse the thermometer to the correct line indicated on the thermometer's body The only two things I wonder about are: 1) Is it possible that steam condensing on the thermometer body just above the water line caused a rise in temp over the 100 degC mark? I'll have to re-do the experiment with some sort of insulation wrapped around the thermometer body where it is exposed to steam... 2) Is there something funny about the geometry of the flask - small opening for the volume contained - that somehow acts to cause a local partial pressure increase making some sort of mini-pressure cooker effect? (I know sounds bogus but I am trying to think of things to disprove my superheating hypothesis...) -Alan Meeker Lazy Eight Brewery Baltimore, MD Return to table of contents
Date: Mon, 07 Feb 2000 20:57:56 -0800 From: Michael Kowalczyk <mikekowal at megsinet.net> Subject: Re: Force Carbonating / O2 / Reversed Cornie fittings This one goes back a while. Thanks to Jeff for talking about his techniques for kegging. It came at just the right time as I had just filled my first 2 cornies and was wondering what techniques I should adopt. I've since drained 3 kegs and force carbonated at 12-17 psi for 3-6 days. You guys are right, CO2 is CO2. NO differences in force carbonating and my bottled brew. I was very pleased at just how easy it is to keg and server perfectly carbonated beer. - ----------------------- Don't want to use the M-word, or report anechdotal evidence, but I just don't see a vast difference between aerating w/pure O2 and not. I even have on tap side by side one brew that was aerated for 90 sec w/pure O2 and an airstone and one brew that was just xfered to the carboy. No splashing and no aeration whatsoever. Both had PLENTY of very healthy fermenting yeast at pitch time. Taste them and one does'nt blow the other one away. Sure they are different beers, with different grain bills, mashed at different temps, and fermented with different yeasts (can I change just ONE more thing!) but I was expecting quantum leaps here. I've been through almost 50 brews without pure O2 and only one with, so I'll give it a chance. At least it didn't degrade the taste! ----------------------- I'm a very satisfied customer w/Beer Beer and more beer. No affiliation blah blah blah. It seems the 4 kegs that I got from them have the in and out fittings reversed. I suspected this when I tried to use the carbonator and it would'nt fit. It's true they are switched. Can I just switch the fittings on the cornie myself? Is this a pain or a piece of cake? Can someone describe it to me as I am a cornie virgin. Again BB&MB has always been very good. I would just like to start using the carbonator cap and that cute little portable serving tapper that BB&MB sells. I can slowly change the fittings as I fill the carboys. ------------------------ TIA, Mike Return to table of contents

Date: Mon, 7 Feb 2000 12:10:55 -0500 From: "Houseman, David L" <David.Houseman at unisys.com> Subject: Valley Mill Heads Up Wes Smith's story of his Valley Mill had me thinking. While I haven't had the specific problem of something getting into the mill and grinding down a roller, his experience of the mill stalling and having to be prodded occasionally is familiar to me. I suspect this is due to the second roller not being driven by any gears so unless some grain is between the rollers for the drive roller to cause the second to turn, then it doesn't. And if the grain trying to get to the rollers hits just right, nothing goes through, the second roller doesn't turn to help the process and things bog down. Prodding with a piece of wood, or preferably opening the gap slightly and momentarily, seems to work. I've thought of modifying the inside of the hopper to provide a greater roller area for contact with grain. This would allow the mill to grain more grain in a unit of time and give more contact area to potentially stop this stalling. Has anyone with a Valley Mill made such modifications to the mill's hopper? Dave Houseman Return to table of contents

Keith MacNeal said... >I made the assumption that 1 lb. of whole wheat flour = 1 lb. of whole wheat >grain. I follow Rajotte's suggestion and use a sifter to add the flour to >the mash. No guey sparges yet. The flour you buy in your shop will probably not contain all of the bran, though it will be better than using white flour. The problem you may find a subject covered in earlier digests ) that the wheat used at the mill would be predominantly hard endosperm wheats - breadmaking varieties. Your US home-grown breadmaking wheats are very hard, and tend to have a high gluten level compared to the low gluten, soft endosperm wheats used in the brewing industry in Europe. High protien is linked to high nitrogen levels too, so beware the haze in the beer! Mind you, for a proper rendition of Hoegaarden, it must be hazy!! The most popular wheat for brewing is one called Riband, this is a Class 3 wheat (European classification) and is gradually being by it's siblings - Consort and Claire. EDME wheat malt extract is made using these varieties. So if you want to add wheat to your mix, and you want the right stuff but can't get European raw wheat (I suppose I could start up a business to ship you some!!), try EDME Wheat Malt Extract. I would go as far to say that Munton's would be the same, as the last time I delivered grain to their maltings, there was only the one variety marked up on the bin listing, and that was Riband. Strangely enough, Riband, is the most popular wheat variety used by the Scottish malsters for Distilling.

Date: Mon, 7 Feb 2000 09:25:54 -0800 From: "John Palmer" <jjpalmer at gte.net> Subject: I don't think Color is important. I am not trying to be an ass. While I thought the discussions about how to measure beer color were technically interesting, I wanted to at least raise my hand and say that I (for one?) don't think beer color is important, even when it comes to targeting a specific style. The reason I don't think color is important is that I think that the driver is flavor. Whenever you attempt to duplicate a style, you are using a similar grainbill to that used by the original. So, by and large, whatever you end up with is almost certainly within the normal color range of the original. Or let's say that you are trying to brew a light color style with higher alkalinity water than the original beer. Eg. brewing Pilsner nearly anywhere else in the world. You are trying to target a particular malt flavor. If you add darker malts to balance your alkalinity, you are going to end up missing your malt flavor target to achieve the right mash. Therefore, you need to change your brewing water, therefore your grainbill and color will end up being within the normal range. I know that most of you (Spencer, AJ, et al.) realize all this and that Color's Importance is not what you were discussing exactly, but I have seen many new all-grainers in our club and on the newsgroup, that try to develop calculations for predicting color and get wrapped around the axle trying to control it in their brewing. So what I want to say is: "Don't; it is not important." If you get the other flavor parameters right, and your brewing procedures are good so that clarity is not an issue, then proper color will follow naturally.

A professional filter guy responded that activated charcoal tends to give off all of the accumulated crud it's adsorbed when heated above 100F or so. So keep those filters cool.... I wonder what my "hot charcoal bitter" is going to taste like? Could be ugly.... Paul Shick Basement brewing in Cleveland Hts OH Return to table of contents

Following the Wheat flower whit beer thread I am curious as to weather the wheat flower needs to be gelatinized (correct term)? By boiling before adding to the Mash? If not why is wheat flower different from Corn meal or Rice? I like the Idea of using wheat flower but would like to avoid carrying excess starch over from the mash. Or would not boiling just affect the amount of conversion from starch to sugar? Dan Klinglesmth about 450 miles south south east of 0/0 Renner Return to table of contents

Sounds >like a fun thing to do. Perhaps even toasting the corks a bit could bring >out more cork character. I dont know if it is due to mellanoid reactions, a calcium defficienty, or excess tannins leaching from the cork, but my corked beers definately develop a musty celler flavor with time. It really adds the "final touch" to some of my big brews and I enjoy the flavor. The flavor does take a while (6 to 8 months) to develop. But since these types of beer are ment to last, waiting is not a problem. Anyway, I brew a Bier De Garde every year or so and try to cork at least a case of champagne bottles. Whenever I make barley wine I also cork a case or two. I use straight wine corks that I get at my local brewing supply shop. My bench capper has a handy corking device that works very well. After corking, I seal the bottles with a standard crown cap. I tried it without the crown caps once and had a few bottles push their corks out. Wire cages work too, but the crown caps are easier.

I was amazed and most gratified at the many helpful responses I got. There were far too many for me to thank you all personally, but I must say that this is the best and most helpful of the half-dozen or so lists I subscribe to on various topics. Some of the nicest replies came from folks in my area inviting me to attend the next meeting of the local homebrew club in Roanoke, Star City Brewers. Unfortunately, a family emergency called me away from home, so I was unable to attend. I will continue to be out of town doing what's got to be done for some time, but will attend the next meeting I can get to. Sounds like a great way to further my nascent homebrewing career along and meet some fun people to boot.

Date: Mon, 7 Feb 2000 17:36:27 -0500 (EST) From: MICHAEL WILLIAM MACEYKA <mmaceyka at welch.jhu.edu> Subject: Yeast looks and growth, and corks Howdy, On Yeast morphology: Tom scoped an infected beer and saw two different morphologies of "yeast." I have often used a microscope to look at brwing yeast, including 1084, and it sounds like the "two yeasts" you see are in fact of the same strain. I often see these different morphologies in medium when the cells are derived from a single colony. I have attributed the differences in morphology to be due to different stages of the cell cycle (based on budding - usually more ovoid then spherical) or metabolic state (vacuolar size). I don't know what the stain is, but it is not impossible that the same yeast would stain differently based on metabolic state. I might thank that the cocci you see are the source of the infection. Uhm, duh. But it may be that the taste defects you note are not due to the infection but due to problems in process. Like the fact that you underpitched. Just a couple of thoughts... Yeast Growth: Another thought, on Pat Babcocks wonder-foam stopper. If this stopper allows air through, then I am not at all suprised that those yeast would grow more quickly and come to a higher density. Contrary to Dana Edgall's idea that you don't get much air into a flask (though he was talking about a stirred flask, which is better for this), I have grown yeast in closed (but not sealed) flasks in medium that required O2 for growth. Oxygen gets in. On Corks: I have often assumed that the "musty" flavor was due to the fact that the beer was corked (either coming from cork contact or gas exchange). So when a bunch of Unibroue flooded the mid-Atlantic a few years ago, I bought a bunch and did a bit of an experiment. I bought some La Fin Du Monde, both in capped and corked bottles. The beer pretty much the same at the time I bought it (though the corked bottle were a little less carbonated). After a year or more of cellaring, the corked but not capped bottle developed a flavor I have often associated with all the "clearance" corked Belgians and which I assume are old and I assume have the flavor we are all talking about. Alan Meeker and I have have bottled a barley wine in both capped and corked bottles, but the corks didn't make a great seal and perhaps enough time hasn't passed to develop the "cork" flavor we are looking for, because the corked bottle sdon't have it. Just some "data," and I'll report later with more as this batch ages. Mike Maceyka Baltimore and Takoma Park, MD Return to table of contents

What I would like is a small sized, self contained cooling unit able to chill down to about 30F - something like a small version of the cooling units they use on walk-in coolers.

Date: Mon, 07 Feb 2000 21:07:29 -0500 From: Glenn Matthies <borst at wzrd.com> Subject: CP bottle filler Greetings, I have a question regarding bottling with a CP (Counter pressure, not Charlie P) bottle filler. I CP bottled an oatmeal stout last month. It was fermented (OG 1.046) 1 week in the primary with Windsor Ale yeast (dry) and racked to a secondary. It spent 10 days in the secondary. The stout was kegged in a corny keg at 8 psi at 55 F. After a week, I bottled into four 1 liter ez-cap swing top bottles. I ran the bottles through the dishwsher w/o detergent and used the hot dry setting to sanatize. I covered the tops with aluminum foil and chilled in the brewing refridgerator. I CP bottled without incident. Two days later I took one bottle to a homebrew tasting. The stout was slightly drier that the original kegged version. Two weeks later, I took another bottle to a brew club meeting. The beer was now very dry and had a fine sediment in the bottle. It appears the yeast started back up again after bottling. The kegged stout has not continued to ferment. What happened? Why did the fermentation restart? How can this be prevented?

Date: Mon, 07 Feb 2000 23:44:01 -0500 From: jim english <jimebob at mindspring.com> Subject: Wierd starter and brew Made my usual 500mL starter solution and pitched a bag of 1056 that was so fresh it had swollen to the point of seeping from one of the seams of said bag within 6 hours. Good start IOW. All appeared normal for a day, or so, but the "krausen" never fell. Not for five days! The "beer" under the foam looked normal, but a thick layer of brown topped foam never redisolved. It smelled OK, albeit a little phenolic. I forgot to sample the "beer" and that may have been a big mistake. I'm starting to worry it was contaminated. I followed my usual protocol (i.e. a strong iodophor solution for plenty of time and a quick rinse with tap water...not ideal but adequate lots of times in the past) to sanitize the mason jar I make starters in. I don't think the sanitizer caused a problem as there was ample evidence of a good fermentation and the "beer" cleared pretty well. Now as to the brew itself. I seem to have read of the phenomenon I am experiencing in the HBD before but cannot recall what the consensus was. I boil and cool in converted keg with an immersion coil. The cold break I get in the fermenter (carboy) is usually rather fine and settles readily. Not this time. Frankly it looks disgusting. Big, cottony globs, floating at all levels of the carboy. When disturbed they seem to want to float to the top. They must settle, but verrrrry slowly. Also my fermentation is real sluggish. My plan is to let it ferment for three or four days and see if the yeast gets a little livelier, and if not, to pitch some additional dry (perhaps champagne) yeast to help out what are, obviously, some subpar yeasties. Once I feel the brew is adequatly attenuated, I may just crash cool it to settle out the rest of the "stuff", if it's still floating around in there. I suspect it's just some proteiny "stuff" (scientific jargon alert) and no big whuff, but it sure is scary looking. Anybody out there encounter either of these anomalies?
