I thought I saved it away, but now cannot find it. I tried the HBD archives, however, the 2002 archives appear to be offline. Can someone please send me the link?" I know that Nate Wahl, the author of that document, moved his website recently. I can't find his new URL, but I do have the document. I can convert it to a .pdf so that it doesn't "limit the audience". Maybe I'll even use the MS Word spell-checker on it first ;^).

Date: Fri, 31 Jan 2003 16:24:58 +1100 From: "Chris M" <chrismac_aus at hotmail.com> Subject: Yeast Starter Dilema Hi, would appreciate some feedback on following. Have recently moved to liquid yeasts and the LHBS recommends sterilising a 2L coke bottle and adding DME and luke warm water to liquid yeast to create a large starter, after a day or 2 the air lock bubbles and i transfer to sterile stubbies put in fridge. I was going away for a week last saturday and thought i would use one of the yeast stubbies for a beer i was planning to start on the day i was leaving, i filled a 1.25L coke bottle, added some wort and tablespoon of caster sugar ( was in a hurry and had no DME ). The yeast is Whitelabs Irish Ale and the wort is 15L of fresh Amber Ale made by ESB HBS in Sydney. I ran out of time and asked my partner if she would make up the brew for me, anyway, she was unable to make beer for me and i have returned home 5 days later and the yeast starter is still sitting on the kitchen window sill where i left it ( avg daily temp has been 25C inside ). Q - Is it safe to pitch the yeast after 5 days, there is no bubbling and i have swirled yeast around today but am unsure about using. The colour of the liquid is amber. I usually make extract beers but have purchased 15L of fresh wort from LHBS to give me an idea of mash beers, thinking of moving to grains. Should i make a fresh stater. Thanks. Chris MacFarlane.

I'd paid for several issues during their going-out-of-business sale. However, since 1999 I had not received the magazines. I recently became aware of an email address for Stephen Mallery (brewtech at earthlink.net). I emailed Stephen and asked why I never received the magazines. Stephen was willing to fix the problem. Apparently there was a mix up with the firm handling the orders. Bottom line -- today, Thursday January 30, 2003, I received 10 "Brewing Techniques" magazines in the mail. If anyone has an outstanding "Brewing Techniques" order, please contact Stephen Mallery for resolution. Also, to complete my collection, I need the following "Brewing Techniques". Please email me with condition and price. Thanks. I need: 1993 Vol 1 Numbers 1, 2, 3, 4, 5 and 6; 1994 Vol 2 Numbers 1, 2, 3 and 4; 1995 Vol 3 Number 1. - -- Kraig Return to table of contents

The Members of Barleyment website can be found at http://barleyment.neap.net/ but I do not think this is where you would have seen it. Perhaps on Strangebrew Drews site http://www.strangebrew.ca/ I've done quite a few beers with S-189 and W-34/70 and absolutely love them both! Very clean yeasts and both seem to be able to easily handle regular (low) lager temps. I've successfully fermented them under the lowest temp recommended by DCL. Used S-189 in a cyser as well and WOW I love that cyser! S-23 I've unfortunately only used once and it was not lagered as low as the others (not because of the yeast, but because of lack of space in the lagering fridge so it went at cellar temp 50F), and I sort of messed up that batch in other ways so I cannot really comment. cheers, -Alan - -- http://www.bodensatz.com/ The Beer Site (tm) Return to table of contents

It was 65 degrees! The light switch was broken and the light was on the whole time. At first I thought maybe this is why it was so warm. Wrong, the fridge is toast. So now I need to do something fast. I am in the middle of lagering a Helles, Bock, Pilsner and Wheat Beer. Does anyone know of a model freezer that can be drilled to allow tap lines to exit it. I have seen some with modified tops that incorporate the taps in the front of the freezer. But I need the tap lines to exit through the top then through the wall that leads to my bar. Any ideas or suggestions would be great. Thanks. Oh yeah I finished my conical and the total cost was 278.00. I am happy with this.

I'm talking about deciding on the recipe and grist bill the hops you'll use. That requires thought and Promash is no help there. > So, that's just over four hours. In the original post I did mention this was > possible assuming the water and grains were dealt with the night before. By that measure it's possible to 'brew' in 15 minutes if you do all the work the day before and after. My point is that real brewing includes all the phases beginning with brew design and ending with aerated and pitched wort in fermenters. When you add that up 6 hours isn't abnormal. I see a number of holes in your list Marc; no time to measure hops, no time to sanitize fermenters a few other items missing. You select minmal figures for mash(30miin before the MO boost), for boil (70 min) and assume that your water requires no salt addition or hardness reduction. I can't believe you brew a BoPils and a Burton ale from the same water. > Like > most people, I'm very time-constrained. Spending four or five hours doing > anything is a luxury so I jam as much in to that time as possible. I understand that and I think you're cutting some corners in a very judicious way, but it's minimalist brewing in 4+ hours PLUS some previous day work in the best case. I think realistically your above 5hrs total at a dead-run. -S Return to table of contents

I'm interested in purchasing one. I'm hoping I could save a little time on the investigative side and get opinions from brewers out there who already bought one. What are the best brands and models I should look at? Any special features or options that should be considered? Where do you buy your bags for vacuum sealing? I'm also interested in getting a digital scale so I have the same questions about that too. Your help and advise would be appreciated. Thanks Paul R Return to table of contents
Date: Fri, 31 Jan 2003 09:24:56 -0500 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: manifolds and pumps Dave Riedel says ..., >How do these pump >systems work for a manifold-style mash tun? Like a champ. Generally manifolds will offer a little less yield and modestly greater chance for channeling than a plate. See John Palmer's excellent analysis. Even John admits the deficits are minor with a well made manifold. In my experience the benefits of manifolds are they are considerably less prone to sticking and develop a better flow rate. Also there is no underlet loss, no grist trapped under a plate and if you attach the manifold to an 'up tube' you can add or remove the manifold at will. The manifold on an 'up-tube' with pump has been dubbed a DIMS(drop-in-manifold system) by a friend. My friend uses a DIMS in a 55gal stainless barrel mash tun ! He can heat and stirr with a motorized stirrer to accomplish mash steps, then he insert the manifold after mash-out temp is reached. He can also decoct by inserting the manifold and pulling most of the liquid off before thick grist decoction.. I use my DIMS manifold (after sanitizing) to pull wort from the boiler thru the CFC and leave whole hops behind. Dual use in the mash-tun and boiler. I describe DIMS and compare this to other systems an upcoming Zymurgy article. There is no reason that a manifold can't be used with HERMS or RIMS - it's an independent feature to the system designations (RIMS, HERMS, DIMS, CHERMS, ...) - which are distinguished by the heating method. -S Return to table of contents

Date: Fri, 31 Jan 2003 09:52:58 -0500 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: oxidatioin - no way .... John Misrahi notes, > I have been trying to improve the technical side of my > brewing from batch to batch, and one of the things that keeps > coming to haunt me is oxidation. No matter what I do, almost > all my beers seem to end up developing an oxidized quality > (kind of a stale wet cardboard taste). Can't possibly happen. I've been scolded at least 100 times on this forum by folks who pour their hot wort blithely through the air that their beers are perfect. I don't believe it myself. That doesn't match my experience, but I tend to keep beers around in keg for long periods of time. I've been adding small amount of potassium & sodium metabisulfite to the mash, but you should calculate the amount so you hit around 20ppm of SO2 in finished wort. This and even higher doses work well in ales. For lagers you need to be concerned with the sulfate products giving the beer a slightly Burtonesque palate at higher doses. This method was recommended by Peindl and others at VLB in Berlin. Yeast produce a few ppm of sulfite too btw. Liquid SO2 is a better means of adding the antioxidant, but it's difficult to handle - not recommended for the amateur. The cardboard flavor is specifically due to an aldehyde breakdown products the most common fatty acid(FA) in grist and hops - linoleic. Once the FA is oxidized the breakdown is inevitable but slow in coming. Where exactly the oxidation takes place is a matter of debate, but it's likely that lipooxidase enzymes from the grist enhance FA oxidation during the low temp mash rests. Don't overextract the grist - late runnings have much more fatty acids than early runnings. Be sure to remove as much break as possible either at the boiler or else rack the beer 24 hrs after pitching. Unrelated to cardboard flavor but getting the yeast out before autolysis prevents certain stale flavors. I agree with the guys who suggest controlling bottling oxygen. Oxygen in the bottle will badly damage beer flavor, but repeated isotope trace studies show that oxygen in the bottle headspace doesn't contribute directly to oxidized fatty acids nor to cardboard-nonenals. Headspace oxygen oxidizes the antioxidants in beer (the good phenols and any residual sulfite), and after this happens the protection from serious oxidation flavor damage is lost. The already-oxidized fatty acids may break down faster due to headspace oxygen, but the oxidized-FA precursor was probably present at the beginning of the boil. -S Return to table of contents
Date: Fri, 31 Jan 2003 10:04:52 -0500 From: "Eric R. Theiner" <rickdude02 at earthlink.net> Subject: Dishwasher Steve Hill asks about the new Maytag 3-level (tall tub) dishwasher. It's interesting that you bring that up, Steve, 'cos we just got the model that's one step down from that one. It has the 2-tier system instead of the 3, but other wise it's the same (except that it was about $100 less and has less nifty gadgets like the funky flatware holder). Here are the things that I specifically noted over the past month. First, the bad stuff: Because the tub is taller (actually it utilizes more space-- it's really not taller), it's a bit further down to the lower rack. This is not a big deal, but it was a little disconcerting that I had to bend down an extra 3 inches or so while unloading the bottom rack. Also, it doesn't seem to wash as well as the old Kenmore we had. Heavily soiled items would put soil into the wash water that is recirculated, and although it does manage to spray that up into cups and so forth, it doesn't get it out. I reject about 4 glasses or cups per load, and because the soil is baked on during the drying process, I need to soak them to get them clean. The system of having a seperate spray arm for each tier is a great idea, but I think that it limits the reach of the water-- same power pump, but it now has 3 (or 4 on the one you're looking at, right?) whirligigs to push, and the head loss because of the nifty routing of water is probably significant, too. Finally, the wash and dry cycle takes more than 3 hours! I am not exaggerating. The worst part about that is the electronic panel only shows when it is washing and when it is drying-- the old dishwasher had a cam-timer (the dial on the front) that showed you exactly where in the cycle it was. Now the good stuff: It's really quiet. No dishwasher is as quiet as I'd like, but this one is much quieter than other ones I've had. The fact that there's no center post in the rack means that you can fit a good bit more stuff in, and more oddly shaped items. I like the detergent cup a good bit better on this one than others, and the rinse aid dispenser gives you a very good idea as to how much is still in the reservoir. The way the top rack is slanted means you can fit some really big things in the lower rack, too. Lastly, the NSF certification it carries means that the when you hit the "sanitize" button, the system will heat the water to 180 F for the final rinse-- this means very easy bottle sanitation!

Date: Fri, 31 Jan 2003 10:28:05 -0500 From: Pete Limosani <plimosani at rcn.com> Subject: Re: Dishwasher In #4159, Steve Hill inquired about dishwashers for sanitizing bottles. Don't know about the model you are looking at, Steve, but I can give you some general comments. I bought a new dishwasher last year that has good features for sanitizing bottles. High Temp Scrub & Sanitizing Rinse. Buttons on the front panel give one the option to turn these features on. When these options are on during the wash and rinse cycles the heating element in the d/w heats the water to a temperature quite a bit higher the ~125* of the average domestic water heater. I cannot remember what temperature it gets up to. But you get the idea--heat kills. I do not use quick dry/air dry. That way when the rinse cycle is over the heating element remains on and the heat stays high for a period of time longer. When the cycle is done the bottles are very hot to the touch. I need to leave the door open for a few minutes to allow them to cool. If I were to buy a new dishwasher, I would definitely look for these two features again. Rinse Aid. My dishwasher has this feature. Don't know if you are familiar with it, but you buy this stuff called Jet Dry and inject it into a reservoir in the door. It helps keep soap residue off of glasses. I've read a number of references that claim that this stuff kills head on beer--theory being that the stuff kills foam and if left in the bottle... There is no way to turn the use of it off selectively, so it gets released when I wash bottles, but I have not had any problems with head retention. Maybe the High Temp Scrub releases the film it might otherwise leave. 3 Racks vs. 2 Racks. If you only use 12oz or 16 oz bottles, you might be ok. My dishwasher has 2 racks. The 24 oz bottles that I like to use don't fit in the top rack and when in the bottom rack they interfere with the wash arm under the top rack. I might try taking a couple bottles to the showroom and see for yourself how they fit. /Pete/ ################################################################# ################################################################# ################################################################# ##### ##### ##### ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ##### ##### ##### ################################################################# ################################################################# ################################################################# Return to table of contents
Date: Fri, 31 Jan 2003 08:12:56 -0800 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: Re: Dishwasher Steve asked about the Maytag Dishwasher Funny you should ask. I just bought one, though the one I have doesn't have the bottom rack, it's otherwise the same model. Very quiet, and very effective cleaning. It was so quiet that when we got it, we joked about it. Me: How about those Buc? SWIMBO: I'm sorry you'll have to speak louder. The dishwasher is so quiet I can't hear you. It is amazingly tall inside (I measured lots of dishwashers when I was shopping), and I sorta felt the lower rack was a gimmick. After all, you can stand up virtually any tray on it's edge in there, and they clear the wash arm just fine. Amazing, really, how tall the tub is. The third tray takes some of that height away, so washing your kettle/crockpot or whatever becomes questionable. I didn't think that flat things, which can stand on their edge, and take up little room, needed their own tray. We like it a lot. My wife washes my bottles in it, and it does a good job of cleaning, but even though it claims NSF cert for sanitizing, I'm not altogether sure I'd depend on that alone. Stuff comes out darn clean though. I'm curious about the bottle rack you mentioned. Didn't see that offered. Can you describe it a bit more? Regards, Mike Sharp Return to table of contents

Date: Fri, 31 Jan 2003 19:36:10 +0000 From: "Dave Larsen" <hunahpumonkey at hotmail.com> Subject: Relax and Have a Homebrew Relax and have a homebrew. I'm brewing two batches at the same time for a big party -- a beautiful amber and an oatmeal cream stout. In preparation, I upgrade my keg system to hold two kegs -- something I've been wanting to do for a while. I hook up one keg, full of the amber to force carbonate. The stout is still cold conditioning in a carboy in a small refrigerator. Several days later it is time to clean the other keg to put the stout into it. Now, I just purchased this keg -- a used one from the homebrew shop. So I put water into it, put some air into it, and shake it up real good. When I open it up, it reeks of hops and is all foamy, brown and reeks of hops. I am disgusted. They say they clean these things before they sell them. I do it again. Same thing again. What the hell! In fact every time I do it, it never gets any better. I spray it all out and look inside. Hmmm. It looks pretty clean. I don't get it. The only thing I can think of is the dip tube must be jammed full of gunk that is coming loose when I shake it up. So I try to take off the nozzle holding the dip tube on, to try and clean it. It won't budge. I try everything from wrenches to vice grips. It simply won't come off. Man, I may as well return the thing, if it is that dirty and I cant even clean the dip tube. The next day, I go back to the homebrew shop with the keg and tell them my plight. To demonstrate, I fill the keg up with water, put pressure on it, shake it up, open it up and it is totally clean. WHAT THE HELL! I exchange the keg anyway, take it home, put some water in it, put pressure on it, shake it up. CRAP! The new one is full of brown foamy water the reeks of hops again. That is when it dawns on me. IT IS SUCKING BEER OUT OF MY OTHER KEG THROUGH THE AIR HOSE WHEN I PRESSURIZE IT! The low pressure of the new empty keg was sucking my beautiful, high-pressure amber out of my other keg and through the red high-pressure hose, because I had connected up to the out port rather than the in port. CRAP. So I take all my new air hoses apart clean them all out and put them back together, clean everything, rack my stout into the new keg and everything is well and good. That night as I lay in bed, my mind wanders. I begin to wonder exactly how much of the amber I lost in all the times I hooked up empty kegs to the other side of the line. I wonder. Hmmmmmm. Should I look or leave well enough alone? Hmmmmm. The next morning, before work, I make up my mind. I'm going to open up the amber's keg and look. I do so and, holy cow, it is down about 6 inches or more. CRAP. Oh well, there it nothing I can do about it now. I go to put the lid back on and -- wait, where is the seal to the lid? The o-ring is totally gone. I look everywhere. It is gone, gone, gone! Oh my Gawd! It fell into the amber. IT FREAKING FELL INTO THE KEG. I look at the clock. I am about fifteen minutes late leaving for work. What do I do?!!! Quickly, I fill a bucket full of sanitizer, grab a long spoon, sanitize it, and start fishing around in the keg. Feel something in the bottom, but I can't grab it. CRAP! I grab the carboy that I siphoned the stout out of the night before, sanitize my racking cane, start a siphon. I look over at the clock. I AM REALLY LATE TO WORK! It is then I realize, CRAP, I DIDN'T SANITIZE THE CARBOY!!! I stop the siphon. Look at the carboy and there is about an inch of beer in it. I run it to the sink dump it out, rinse out the carboy and sanitize it, and start the siphon again. Finally, I siphon it down far enough to peer through the top of the keg and see the o-ring. I fish it out using the spoon, siphon the beer back into the keg. My nice clean white-collar-job work clothes are covered in sanitizer and beer. At this point I am not even in a hurry anymore because I am so late for work that I don't even care. I guess I need to start thinking of excuses. Somehow I don't think the beer story is going to cut it. Really, it's time to relax and have a homebrew. *** This really wasn't a major disaster or anything. In the end, all I did was loose a gallon of beer and was late to work. I'm not really looking for any advice from anyone. It is just something that happened this morning and I felt like telling the story. I'm sure people have much worse stories than this one. Anybody want to tell them? Anybody learn any lessons the hard way? - Dave Return to table of contents

At higher temps, it produces more banana and less clove." I don't know if the same will hold true with 3068, but last April, I made a Bavarian Hefe using 3333. The fermentation ran over a week of unseasonably warm April weather, and I suspect it was around 72-74F. After bottling and carbonation, the beer had a *LOT* of banana flavor. So much so, that I didn't really like it (although my wife did). Later in the summer (probably around August or so), I took a sip of a beer she was drinking. I didn't even recognize it--the flavor had changed so much. It was GREAT! The banana character had mellowed considerably and the clove taste had started to shine through. Just thought I'd throw that into the mix. Happy brewing, Jon Woodbury Brewing Co. www.woodburybrewingco.com Return to table of contents
