Poor baby. The cause was his own incompetence. Why should I sympathize with an incompetent businessman who steals my money? It is naive to think that Mallory, having lost his business, is personally broke. Any good accountant will shield a client's personal assets from business assets. Rest assured Robin, when BT went belly up, Mallory's pockets were not empty. Jerry "Beaver" Pelt, also in HBD #3849 ( http://www.hbd.org/hbd/archive/3849.html#3849-9 ), noted that "Peter obviously is not, has never been, nor will ever be a business owner" Au contraire Jerry! My wife and I own my own an incorporated business and have supported ourselves for over 10 years without ripping off anybody. Why did Ken Cada, also in HBD #3849 ( http://hbd.org/hbd/archive/3849.html#3849-18 ), recently get his back issues of BT, but I didn't after having waited all this time? Might be something to do with the BT/CEN name subterfuge that that Jim noted in HBD #3848 ( http://www.hbd.org/hbd/archive/3848.html#3848-28 ). Peter A.

Date: Fri, 25 Jan 2002 21:18:15 -1000 From: "email" <thx1386 at yahoo.com> Subject: CO2 regulator conversion and Airports Greetings Beer people tinkerers, Has anyone out there ever converted or thought about converting an acetylene welding regulator to use as a CO2 regulator for a kegging system? A friend of mine happen to find a regulator while cleaning out his garage and passed it on to me; and I, having no immediate use for it in its intended purpose (I already have a setup.) immediately began thinking "How can I convert this to beer use?" I realize I would need to change the connecting bushing to a CO2 tank compatible one. Is there anything else that I'm missing in this adventure? TIA On that question regarding beer through the airports. I advise caution as your mileage may vary. During the holidays my friends and I came through the airport with bottles of wine. I had one unopened bottle. The guard scrutinized the cap and cork and allowed me through. My girlfriend carried a partial bottle that we hadn't finished in our dash to the airport. The guard held everybody up; looked at it, sniffed it, swirled it, wasn't going to let it through, consulted, and then eventually, after embarrassing my girlfriend and exasperating everyone in line allowed her to carry it through after verifying that it was indeed wine. My friend who followed was carrying two unopened bottles. Security wouldn't let him through saying that passengers were allowed only one bottle per person. Yes, they confiscated the second bottle explaining that it could be used as a weapon. Somehow the logic escaped me. You are warned.

In engineering applications for cable glands etc we use either metric (ie M20, M25) or NPT (1/2" or 3/4" are direct equvalents). I also find it amusing when dealing with US based clients when I quote metric dimensions to be asked for them in English units. I have always grown up with metric as English units!

That name is translated in English, The Stir stick. So I am a redactor of our journal, I often receive questions of beginning brewers. I am functioning also as a mentor for them. One of the questions I last received was a request for Pumpkin beer recipe. It did me scratch behind my ears. Secondly I thought, maybe the American brewers can help me, for they are known as brewers of a great variety of special and rare beers. I hope that anyone can help me and my questioners, in or outside the USA. Martin Hofhuis hofbeer at planet.nl Tilburg, The Netherlands Return to table of contents

I'm wondering if you scoop the foam that appears on the top of the >newly started boil....<SNIP>... If you don't, why not? I've only done this when my hot-side break was about to cascade down the side of the kettle. Otherwise, I just throttle the propane to control the foaming until it's gone. After the foam, but before the hops, I have had occasion to skim little "slicks" of crud now and again, but not very often. No scientific reasoning here, just my method. >Now a brief survey, if a buddy said that he just brewed up his "Smokey >Porter", a really good brew, but found that the rauchmalt was buggy, >would you drink it?

Date: Sat, 26 Jan 2002 09:52:35 -0500 From: "Peter Fantasia" <fantasiapeter at hotmail.com> Subject: Hop Character Mark in Kalamazoo asks how to get more/better hop character in his beers. The tried and true method is to experiment with the 30 minute, 15 minute and the knockoff hop additions. Make sure you're using fresh aromatic hops. If all else fails dry hop. 1/2 oz. to an oz. in the secondary for a week will give a nice aroma. Use fresh whole hops preferably.

Date: Sat, 26 Jan 2002 07:01:05 -0800 (PST) From: Road Frog <road_frog_run at yahoo.com> Subject: oatmeal aroma / First AG Emily E Neufeld <eneufeld at juno.com> typed: "Now for brewing: what is the recommended amount of oats for an oatmeal stout? I used about a 1lb in an 11.25lb grain bill. It has the silkiness of the oats but could use more of the aroma." You have to use aroma oats. When you do this it is best to use noble oats. I use about 1.5 to 1.75 pounds per 5 gallons. Personally I have never noticed an aroma from oats. It is a feel and flavor. Maybe the other aromas mask it. First All Grain Made a copper manifold and rigged a ball valve on the family cooler. Now 7 years later I need to retire the cooler. My wife went and bought her own cooler within a year, but that did not come out of my beer budget. Checked a 50 lb. sack of barley as luggage so I didn't have any shipping expense. Using my homemade grain mill (have to watch that budget) sweated and cussed my way to 25 lbs of crushed grains. I was trying for a 1.080 tripel, figured if I didn't make it I would still have something. Everything went well ended up at 1.072. Way down yonder in the land of cotton.

Master Plumber part #442 (at least in Canada, may be different in the US). Kent Fletcher was indeed correct, they are labeled "Brass locknut for lavatory faucet." Thanks to everyone who responded to my question about RIMS heater control. I guess I should have been more specific: I'm looking for ways to manually control the temp of a 240V electric heater running at 240V in a kettle. A dial-type control like that used on a stove would be ideal. On the subject, I remember reading a few years ago in this very digest that the threads on electric hot water tank heater elements were 1/2", but not NPT. Has anyone mounted one of these threaded elements in a sankey keg? What type of coupling is required? Cheers!

Date: Sat, 26 Jan 2002 09:31:59 -0600 From: stpats at bga.com Subject: NPT nuts I think Earl Gasner has it right. For a bulkhead fitting you are looking for 'parallel' or straight threads, not tapered. The only kind of thread I knew eleven years ago had a needle on one Go to www.mcmaster-carr.com and plug in 'page 3' in the search to get a nice description of the difference between tapered and parallel threads. There is a scale on page 2 that should allow you to determine the size of whatever thread you have. I say should because I haven't been able to get it to print to the same scale, as a pdf or whatever?? btw, page 2 also describes stainless steel, brass, and other materials. Earl mentions 'whitworth' thread (BSW British Standard Whitworth) which you won't find there. I recently came across this and took it to my machinist who identified it. I was told it is not used in Europe anymore (BSPP and BSPT are, British Standard Pipe-Parallel and BSP-Tapered). Earl mentions NC and NF (National course and national fine, straight threads). You won't find them mentioned there either but you will find UNC and UNF (Unified national coarse and Unified National Fine) which aren't exactly the same thing but in practice it doesn't matter since they are interchangeable. NC and NF are the old American threads which became "unified" by NATO to make repair of equipment from different NATO countries easier. There is also metric (ISO metric I think) but I have enough trouble keeping this other stuff straight, or tapered;-) Lynne St. Pats Return to table of contents

Let me add my $0.02 DON'T USE THIS PRODUCT ON STAINLESS STEEL!!!! I learned the hard way. It seems to clean plastic and glass very well, but oh my it did a number on my brew kettle. I filled my 10-gal stainless kettle with a weak solution of OxyClean and water, amused myself by watching it bubble for a little while and went to bed, knowing that my keetle would be sparkling shiny clean in the AM. Yikes -- I woke up and found a black film covering the inside of my kettle, and I fear it's ruined. I've scrubbed and scrubbed, and it looks like I've gotten most of the corrosion/oxidation/whatever it is (?), but I've been afraid to use the kettle again. If I can't use it, I'm out about $120 for a new one... boo hoo hoo. OxyClean doesn't have any bleaches in it, but it sure acted like a bleach on my stainless. chris carson Eden Prairie, MN Return to table of contents

Even with a handle and supporting the bottom of the carboy with my other hand, I managed to bump a 3 gallon carboy on the tile floor and then had 3 gallons of iodophor and glass shards to clean up. I managed to clean and bandage the gash on my hand before I cracked out the wet/dry shop vac (BTW, excellent tool for this kinda mess).

Date: Sat, 26 Jan 2002 12:39:23 -0600 From: Chris <chris at webesota.com> Subject: How do I krauesen my lager?? I have 4.75 gallons of a lager that I'm getting set to bottle. I recently read a couple of different pieces about krausening, and why it's good for lagers that have aged for a couple of months (like mine). "An Analysis Of Brewing Techniques" mentions the practice, as does "The Homebrewer's Companion ". Neither one really talks much about how to apply it to your own little five-gallon batch. I went to a homebrew shop here in the Twin Cities, and when I said i wanted to add freshly fermenting wort to my bottling bucket to prime the beer, the guy helping me (well, not helping me) said, "ugh, splutter, you cant do that!!!" I thought my chances were better here for some expert advice. Specific questions: 1) What kind of yeast? The same one i brewed with? Is there a good, neutral sort of yeast that would be well suited for krauesening because it would not change the brew I'm bottling? 2) How much wort should i use for my batch? My batch is about 4.75 US gallons. Fix (Analysis of Brewing Techniques) suggests 15%-20% of the total volume as an amount to use. However, his examples use sealed tanks that I could vent CO2 from. I am bottling, so I'm thinking that I should use less? 3) At what point do I add the wort to my bottling bucket? Papazian (The Homebrewer's Companion) says 4 to 6 hours, but I have read in other places to add the wort at high krausen (maybe 24 hours or so later)?

Matchuski's 1994 Zymurgy article "Oats: The Right Grain to Brew" and writes: "In oatmeal stout, it [oats] accounts for about 22% of the grist." Now that's pretty specific as I'm sure it varies all over the place, but why not just try it and see how it turns out? I'm not sure if you are going to get much of an aroma over the dark malt. And consider using malted oats (Thomas Fawcett & Sons malt oats). Jeff - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at mediaone.net "One never knows, do one?"

You can rescue it with some hop extract. Dave Miller recommends the pre-isomerized extracts (by dissolving the hop resins and oils in liquid carbon dioxide) because it preserves hop aroma also, rather than just bitterness.

Why, a friend of mine, he is now president of our homebrew club, taught me to do that. He was brewing all-grain at the time and I was just getting into extract brewing. I have been all-grain now for about 5 years. It is suppose to cut down on off flavors. About the buggy beer. I now usually HB and split 10 gal batches with a friend of mine (He has an out of date official Kentucky license plate on the front of his car with KEGMAN on it). About a year ago, when xfering to the secondary he noticed a fly in the primary. We don't know when the little beer stealing devil drank his fill but he, may be it was a she, died with a smile on the face. Anyway, we drank the beer. Kegman called his Fly Trap, and I called mine My Fly. It was one of the better brews, and we do make good beer, we have produced. Kegman through the fly away so unfortunately we can't use it to brew another beer. Not knowing when the fly entered the beer, in the wort while we were sparging, during the brew (how many minutes into it) or in the primary... Just when should one add the fly to the brew? Mike P.S.

I've been reading with interest all of the information on batch sparging. So I modified my instructions, set aside my sparge arm (a.k.a. whirlygig, but relax Dan, I still needed Phil's Phalse bottom), and went for it. 8.0 lbs Briess 2-row 0.5 lbs Cara-pils 0.5 lbs Crystal 60L 0.5 lbs Chocolate 0.25 lbs Black Patent 0.75 oz. Perle 5.5% - 60 min 0.75 oz. Perle 5.5% - 30 min 0.5 oz. Perle 5.5% - 15 min White Labs WLP001 - dregs from an APA - --I thickened my mash up from normal (1.1 qts/lb, normally 1.3 for me). 170 strike, 152 mash-in, only mashing the 2-row, cara, and CM60 for 45 min. - --Added the choc. and BP, and 1.2 gal boiling water, stirred up the thinned mash, hit 168F, and let it sit for 15 min. - --Brought 4.2 gal water up to 180F, poured into a separate bucket and set aside. - --Recirc'd 4 qts of wort (really running clear after three, which surprised me considering the disturbance of the grain bed), put the hose in the kettle, and let 'er rip wide open until the tun was dry, ignoring the sudden cloudiness at the end of the run. - --Poured in the next batch of hot water (most of it), stirred, rested for 5 min, recirc'd 4 qts again (and again, surprised at how quickly the grain bed sets as a filter), and opened up the outflow wide open again, topping off the tun with the remaining water that didn't fit. Results? I normally have been getting 70+% kettle efficiency based on points (80% after boil), and this dropped to the low 60s% kettle efficiency (can't be exact, because the sample I pulled and cooled was just short of floating the hydrometer - I'm guessing 33 pts / 54 pts = 61%). After boil calc was 73%, which yielded in a net drop of 6 points in OG (got 1.050, would have expected 1.056 in my normal setup). Although I didn't save any time overall (still took 5+ hrs), this method certainly nixed the need for a 3rd tier HLT. Given a few modifications to my process, I could get this process under 5 hours. The most surprising item was how quickly the stirred grain bed settled into a nice filter - especially after the 2nd addition of water, which was a large, heavy SPLOOSH of hot water, and a really good stirring. So my one lingering question is about the cloudiness at the end of both sparge cycles. Is there any big deal here? - -- +++++++++++++++ Brian Levetzow ~ Laurel, MD [425.7, 118.5] Apparent Rennerian Return to table of contents

That's one of the things Jethro Bodine wanted to be, a double-naught spy, along with a brain surgeon, big Hollywood agent, and some other things I forget. Anyway, I'm quite sure that that is a myth. There's no reason to think that CO2 "knows" how fast it went into solution. Dissolved CO2 is dissolved CO2. I have a little bit of an open mind as to whether or not "natural carbonation" produces longer lasting or finer carbonation, although I am skeptical. I guess it is possible that there might be some changes in proteins or something, especially in the case of actual kraeusening. But fast or slow force carbonation? No difference. > > Mash 154F 60 minutes. Actually, though, I did a 40/60/70C mash (30 >> minutes at each step) adding the corn at 60C.

I spent 30 minutes at each rest temperature, and took maybe 20-30 minutes to go from 40-60, and I suppose half that for the 60-70 step, using propane and recirculation. I couldn't tell you if fast is better except I wouldn't want to spend too much time in the 50-55C range as the proteins could be excessively broken down. I've only actually had that problem once with a weizen, which had poor body and head retention from too long a rest at 50C. As I implied, this is clearly unnecessary with modern malts, and I don't bother anymore. Even with CAPs, I skip the 40C acid rest and mash in at 63C and hold it there while doing the cereal mash, then boost to 70C with the cereal mash and additional heat as necessary.

I've used One-Step for cleaning and sanitizing now for the last couple years without problems, as per my brew shop's recommendation. However, if people are having issues with it, I may switch. Back in the old days, I used to just use chlorine bleach, but I had a couple of batches that got "band-aidy." Have others had problems with One-Step? Dave Larsen Return to table of contents

But as mentioned, keeping hot AND open is a sure way to disperse them. The "open" part is not an insignificant part of the equation... as case in point I make an "alcohol free" beer at Christmas, which is simply a finished beer that I then bring back up to a boil. After it has simmered a bit, I dump it straight back into a keg and pressurize it, and let it cool "au natural", and it retains a surprising hop aroma despite the abuse.... and I feel pretty sure that "getting it right back under pressure" is the flavour-saver. Along these lines, a "hop back" is an effective little toy for this very reason, methinks.... The wort is exposed to the hops at high temperatures, but there's nowhere for them to disappear to (closed system). On the heat part, I think you'll find much better hop aroma with your planned double cooler system, simply because it cools so much faster and that is one of the key elements. The BIGGEST saving there, is not simply that you have two different cooling systems, but the fact that the counterflow lets you keep the wort MOVING past the immersion cooler, improves its efficiency by a HUGE amount (you get "convective" cooling, instead of just "conductive" cooling for absolutely free!).... this in turn allows the dissolved volatiles to stay just that, and not do the trick of their namesake.... namely flying up into the air.

Any > thoughts as to the ease of this? I use an 8-gallon aluminum kettle this way and it works great - it's easy to do several temperature rests on the stove. After mashing I scoop the mash (this is a bit of a pain) into a plastic bucket fitted with a false bottom. I use another bucket to hold hot sparge water. It's pretty simple and the buckets nest together for storage. Before I got the big kettle I did this with two five gallon pots, mashing in one and using both to boil, which also worked OK although the mashes had to be quite thick with more than about 10 pounds of grain. Also I think I lost more wort trying to siphon away from the break material in two kettles instead of one. Roy Roberts NYC Upper Yeast Side Return to table of contents

Leo responds to Dave's questions about oxylean and One Step: >Dave the problem I see...IMHO One-step is not a suitable sanitizer. >I tried it several years ago, and produced a string of infected beers. >I corrected that by switching to Iodophor. He goes on to suggest that an inexperienced brewer might brew with One Step as a sanitizer and not realize that the beers were mildly infected (Leo relates a anecdote to that effect). I (an inexperieced brewer)found some humor in the possibility that I have been brewing for a year and developing a sense of the effects of various ingredients on recipes and not knowing that, all the while, I have a constant, underlying infection. Maybe I just like the infected taste! I *thought* that One Step was working well as a sanitizer, but I would really like to hear some other opinions on its effectiveness.

I've been involved in a project to make a single gallon of beer and was thinking how easy this would be to do if I only was boiling a quart of water with extract/hops, then adding water to top the wort out to a gallon. I could even use a large measuring cup in a microwave or such. Is there a special reason for bringing wort to a boil, besides the hop extraction, or will there be other, more sinister, effects of using microwaves to do this (I'm just tired of being exiled to the garage during boils because of the smell, then spending hours outdoors in cold weather)?

I am wondering if it is really worth it? The only worry I would have if I would filter beer is that it would lose body and the aromatics and flavor.

My main concern is not the loss of the money but rather the loss of the best homebrewing periodical out there. I really miss it. I enjoy reading BYO but the depth is not there and there seems to be a considerable number of errors in every issue. I also like Zymurgy but I think it has lost a bit of its appeal to all grain brewers with the newer focus on extract brewing articles. I understand the economics of why Zymurgy has simplified its focus, so no need for any comments to that effect.
