I made one myself recently, and it was very close to yours. What I wonder , though, is : what is the effect of a 2 stage rest (ie stopping at 158F) rather than ramping through that temperature range? ie does it really matter with the malts that we use,...or would the resulting brew be different?... ..Darrell Return to table of contents

I don't think it is anything inherently in the coffee, but it is something in the coffee.Jim, I suspect that your coffee is becoming slightly carbonated as the cold liquid absorbs some of the CO2, just like your beer does, and is forming carbonic acid. I would recommend using Nitrogen instead of CO2 - that won't be absorbed into the cold liquid.

Any good beer stores or brewpubs? Is there a local homebrew >store? How about a homebrew club? Do people brew all winter? I'm living >in the South right now, so the concept of "winter" is still a little bit >odd. I am not too sure about homebrew supply stores on the Vermont side, but this area is really the homebrew supply doldrums. The is (or perhaps was) a shop in West Lebanon, NH. It is the Seven Barrel Brewery (also you closest brewpub). I just heard last week that they may have closed the homebrew shop adjacent to the brewpub, but I have no confirmation. The other shops in New Hampshire aren't even close to Hanover, Jasper's in Nashua and Stout Billy's in Portsmouth. They are both pretty decent supply stores though. On the New Hampshire side, The Flying Goose in New London is not too far down I89 and Elm City Brewing Company in Keene is a short drive from Hanover as well. Now the really good news is that you won't be too far from McNeill's in Brattleboro, Vermont. As far as beer stores are concerned, you will probably find the stores in New Hampshire are mostly bad. You will find locally brewed beers here and there along with megaswill, but not much else. Vermont has some really great beer stores, but I have never shopped near the NH border there, only up in the Burlington area. Phil Sides, Jr. Silver Spring, MD Need a good laugh today?

Date: Sat, 26 Apr 2003 16:32:36 -0400 From: David Towson <SpamSink at comcast.net> Subject: Re: Kegging Newbie In HBD 4230, Caryl (BTW, how is that pronounced?) asks several questions concerning kegging. 1. "Is it possible to bottle and keg each batch?" Yes indeed. I do this from time to time. I start by kegging all the beer, and then I bottle from a keg using 3 - 5 PSI of CO2 pressure to pump it out. After purging the keg with CO2 (I fill it completely full of water, and then pump out the water with CO2 pressure), I boil my priming sugar in a little water and pour that into the keg. Then, I run the beer into the keg through the liquid-out fitting so it is discharged at the bottom of the keg with no splashing, and it mixes with the priming sugar solution. Then, I close the lid, add the CO2 pressure, and proceed with bottling from the keg. After filling as many bottles as I want, I leave the rest of the beer in the keg, all primed and ready to self-carbonate. 2. "Anyone [have] problems with priming in kegs?" I don't, but it won't work unless the lid is sealed. And that means you will have to put about 5 PSI CO2 pressure in the keg after filling to seat the O-ring around the lid. 3. "Are they hard to clean/santitize (sic)?" No. Since the lid is big enough to admit your hand and arm, you can use "elbow grease" if needed. But that is rarely necessary once the keg has been thoroughly cleaned initially. To scrub a keg, I use a ScotchBrite pad and some oxalic-acid-bearing scouring powder. The brand that I can get locally is called "Zud", and I can find it in both grocery and hardware stores. There are others, but I don't know the names. This stuff does a superb job of cleaning stainless steel, but it does leave a dark residue if not rinsed very thoroughly. To be sure of removing that, I always wipe the cleaned surface with a damp paper towel. And BTW, this cleaner does a nice job of prettying-up the outside of the keg too. Once I have gotten a new keg clean, I usually just use a short soak (15 - 30 min) with a chemical cleaner after each use to get it ready for the next time. There are lots of cleaners to pick from such as PBW, Straight-A, B-Brite, and TSP. But look at the inside of the keg after the chemical soak, and if it doesn't appear clean, then grab the ScotchBrite and go at it. To sanitize my kegs, I use Iodophor. Five minutes contact time is plenty. Star San also works well, but I think it's rather expensive. You can also use bleach, but it's very important to get it out of the keg as soon as it has done its job, because it will corrode stainless steel if left too long. I don't know the minimum contact time for bleach, but fifteen minutes should be enough, and that little won't hurt the keg. 4. "...how long will a kegged beer last after being tapped?" I don't think the act of tapping has anything to do with it. If the beer is handled well and not allowed to pick up oxygen, then the beer will last as long as it would in a bottle. But keeping air away from the beer is much easier in a bottle than in a keg. Once you have filled a bottle to within an inch or so of the top, there just isn't much surface area left to be exposed to air. But in a keg, there is no narrow neck to limit the exposure, and you have to be careful to keep a blanket of CO2 on top of the beer. That's why you purge the keg first, and then flow the beer in quietly under the CO2 blanket. It's also a good idea to cover the open top of the keg with a paper towel while you are running-in the beer so room air currents don't disturb the CO2. 5. "Is there any problem with tapping and untapping(?) a keg over and over?" Other than it's being messy, I don't think so. But each time you remove the liquid connector from a pressurized keg, a little beer drools down the side of the keg, and you have to clean it up. And given the low cost of connectors, hose, and picnic taps, it hardly seems worth the bother. Just make-up as many serving hoses as you need, and be done with it.

I haven't devised a hold-down for my lid. . . Steve - Two words: Binder Clips. I use six of the medium sized clips to seal the polycarbonate lid I made for my CCF. Works like a charm. It started as a temporary solution, but works so well, I don't plan on changing it now. I may, however, get some silicone tubing instead of the "D" shaped neoprene door gasket (Lowe's) I'm currently using (though it's working well, too, and I have plenty of it - I've been using a new piece every time). Then, on Fri, 25 Apr 2003, Kegging Newbie Caryl Hornberger Slone <chornberger10 at comcast.net> asked: > Is it possible to bottle and keg each batch. Maybe I cold just start making > 6 gallon batches: keg 5 and bottle 1. I'd add sugar to prime the whole > batch. Anyone problems with priming in kegs? Are they hard to > clean/santitize? You could do that. Or you could just keg as much as you want unprimed and force carbonate, then bottle the rest, dropping a couple of PrimeTabs (NAJASC) in each bottle. > But this still leaves the question, how long will a kegged beer last after > being tapped? Since it's filled with CO2, it should be a while. Lets say I > have a couple of kegs and I want to drink a glass or two from a different > keg each night. Is there any problem with tapping and untapping(?) a keg > over and over? Why? Just get more taps! I've got two 5 gal. kegs and two 3's in the little chest freezer I use. Most of my brews are on tap for a couple of months. I keg the brews I drink more of (rye ales, stouts, pales ales, pilsners, etc) in the larger kegs, and stuff like imperial stouts and other high gravity brews in the 2.5's or 3's. Four is enough, isn't it? If not, you still have aforementioned bottles. > I wouldn't refrigerate the kegs since I don't have fridge room. . . I'd recommend making the fridge room. It takes a lot more CO2 to carbonate warm beer, and it sounds terribly complicated to come up with a chiller compared to picking up a small chest freezer for a hundred and a half or so. > If anyone knows of a good FAQ for kegging that would answer all my > questions, please point me that way.

Date: Sat, 26 Apr 2003 19:50:00 -0400 From: Bob Hall <rallenhall at toast.net> Subject: I agree that Stan Burnett is a lucky guy. Bohemian lager in the smaller towns like Tabor is still quite a bargain. My wife taught near Havlickuv Brod during the 96-97 school year, the home of Rebel which is currently being imported to the US. Good Czech lager, but during my visits I kept going back to the taverns that had Urquell or, as Dr. Pivo suggests, Bernard on tap. We've been back several times since and though the beer may or may not have changed much over the past decade, it still seems like another galaxy compared to what is mass produced here.

Date: Sat, 26 Apr 2003 19:33:34 -0500 From: Michael <grice at binc.net> Subject: Pump question (summary of responses) Originally I asked if the pump I bought (model H315 from morebeer.com, March model 809HS) a) needed priming and b) how important placement of the pump was. I also mentioned c) that I had trouble getting flow through my Easy Masher when I use hop pellets and Irish Moss. Enough people responded to me off the digest that I'd like to summarize (for the benefit of anyone searching the HBD, if nothing else). 1. You'll need to use gravity to get liquid flowing into the pump. Lou King suggested to put the pump at the lowest point in the system and let it push the wort back up. The pump should have no problem pushing the wort back up, and it will be easier to prime. 2. Don't let it run dry! (I did have this one figured out already.) 3. Use a ballcock on the output end to control flow. If you try to restrict flow into the pump, the pump will run dry. (I had not figured this out.) 4. The quick disconnects from US Plastic will clog if the very first runnings from the mash contain particulate matter. Recirculate by hand, then use the pump. 5. Use whole or plug hops. Whole hops will act like a filter; a ratio of 2 parts whole hops to 1 part pellet hops was recommended. I tried this today with my Easy-Masher and whole hops, and it worked quite well. ( I don't have the disconnects yet, so I didn't use the pump.) Thanks to Kent Fletcher, Lou King, Mike Zapolski, Josh Jensen, Maury, Kevin Mueller and John Scime, and I apologize if I've missed anyone. Return to table of contents

Bottles - I get mine from the local beer warehouse. They won't sell me beer because I have no license, but The Budwiser Distributer will sell me nice heavy Budwiser Boxes full of empty bottles for $2 per case. They are mixed, have cigaretts in some, etc. I soak them in 1/2 cup chlorox to five gallons or water for a week to remove nasties (human induced and otherwise) and to loosten the labels. Scrub, inspect, sort, etc... 2. Starch Haze - along with protein haze, I can not taste it, so I don't worry about it unless I'm brewing for a comp. If I'm brewing for a comp, I don't worry about it either, because I don't brew specifically for comps either... 3. Sealing a SS Conical - My SS Cylindor-Conical is a 16.5 gallon custom made one. The lid has a 2" lip around it and drops down to cover it quite nicely. That said, I am concerned about fruit flies that seem to love the smell of fermneting wort. I am planning on drilling a hole in the top for an airlock, and will duct tape the lid in place when fermenting during the warmer seasnons. Yup, I'm lazy.... Wit Brewed two batches recently. One 1.050 OG mashed in a gott and one 1.069OG mashed in the half barrel system ont eh same day. Same basic recipe, just more of the same in the high gravity version, and I added black pepper to it. Both are really good. In fact, I'm having a glass of the stronger version now. Be aware that Bulgar Wheat will give a good bit of color, so it is not visually a good wit but tastes great.

Date: Sat, 26 Apr 2003 22:13:13 -0400 (EDT) From: "Christopher T. Ivey" <cti3c at unix.mail.virginia.edu> Subject: stats and Excel How did we get so far afield of beer & brewing? I'll try to make it quick... AJ advocates using a computer to calculate p-values from the binomial distribution, and I couldn't agree more strongly! Why do this stuff by hand (or even with a hand calculator)? I wouldn't necessarily trust the results from Excel though. Earlier I lambasted Excel's performance for routine statistical calculations, but AJ defended its reliability. L. Knusel, writing in the journal Computational Statistics and Data Analysis (1998, vol 26: 375-377) says about Excel that "...the computation of some discrete distributions [including the binomial] fails even for probabilities in the central range between 0.01 and 0.99 and even for parameter values that cannot be judged as too extreme." and cautions against "using Excel functions for scientific purposes." This sentiment was also echoed by BD McCullough and B Wilson, who said in the same journal (1999, 31: 27-37) that "Excel's performance in [estimation, random number generation, and statistical distributions] is found to be inadequate. Persons desiring to conduct statistical analyses of data are advised not to use Excel." Again, these tests are based on standardized tests using datasets produced by NIST. The problems were reported as early as 1994 in Excel version 4 and persist (or in some cases have worsened--see McCullough & Wilson 2002, Comput Stat Data An 40: 713-721) through current releases (Excel 2000 and XP). I use Excel regularly to move numbers around, sorting, organizing data, etc. I would never trust my data, however, to those pre-programed "functions." Jon Honeyball (writing in PC Pro, December 1999, Issue 62: 248-255) summarized the problems with Excel's statistical calculations as, "...the only applicable words are 'avoid' and 'plague.'" But hey, unless Paul is planning to publish the results of his triangle test in a peer-reviewed journal--maybe it's close enough! Chris in Champaign IL Return to table of contents
Date: Sun, 27 Apr 2003 08:04:58 -0400 From: "Dan Gross" <degross at starpower.net> Subject: More on harsh bitterness in CAP Thank you all for ideas on the cause of a harsh bitterness in my first CAP. Jeff Renner asks if I checked the ph during mash or runoff. No I didn't and I certainly will do so the next time. One other thing I didn't think about until after posting my first message last week was that I might have mishandled the yeast and caused some sort of problem. I had intended to brew about two weeks before I actually got the chance and so I kept stepping the yeast up in a gallon container for almost three weeks. I would let it ferment the starter for two or three days then pour off the beer and add another half gallon of wort. This probably added up to about five generations before I actually pitched the yeast in the beer. I wonder if I caused a problem somewhere along the line. I did end up with a large quantity of yeast and the ferment went quite well at 48 degrees. I can't wait to give the CAP another try because up front I can taste a hint of what it is supposed to be like. Also this is the best looking beer I have every brewed, it is crystal clear and the head is like whipped egg whites. If I ignore the bad finish, it has real potential.

Date: Sun, 27 Apr 2003 19:24:06 -0400 From: "D. Clark" <clark at capital.net> Subject: bottle conditioning w/wort Hi list, Here's a question for the collective. I have been all grain brewing for a while now, and all of my beer goes into kegs, but on occasion I will put up a six pack if I happen to have over 5 gallons or if I want to enter a brew in a local competition. To condition my beers, I have been using primetabs with what I would call only limited success. I have put four tabs per bottle and have seen only mild carbonation in three different beers. I had much more CO2 production using corn sugar or DME when I was bottling. I have a wit in secondary now. I saved out wort from the boil to add to my bottles when I was ready to keg and bottle this batch. How much raw wort should I add to each 12 ounce bottle to achieve good carbonation? O.G. was 1.042 for 5 gallons and was 1.010 in the secondary. Any help would be appreciated. Dave Clark Eagle Bridge, New York Return to table of contents

Date: Sun, 27 Apr 2003 23:41:32 -0400 From: David Humes <dhumes001 at comcast.net> Subject: Predicting mash pH I was wondering if anyone as some practical experience with the Kolbach equation for predicting mash pH? It shows up in a couple of the popular homebrewing books with rather obvious mistakes. AJ posted what I believe is the correct equation in HBD #2648. It goes like this: pH = 5.8 + [0.00168 Alk(ppm as CaCO3) - 0.0012 Ca(mg/L) - 0.000982 Mg(mg/L)] It is assumed that a 100% pale malt mash in distilled water will have a pH of 5.8. I routinely achieve a mash pH that is lower than what this equation predicts, which is good. But I wonder why the equation fails to provide a useful result. My water has 50ppm Alkalinity, 25.8ppm Ca, 6.3ppm Mg and a pH of 7.8. For a Bavarian wheat that I brewed yesterday I added an extra 50ppm Ca in the form of CaCl2, so the total Ca was about 76ppm. The Kolbach equation predicts a pH of 5.8 for this mash, but I hit around 5.5. The recipe is 61% wheat, 31% Pilsner, and 8% Munich. I know that Munich is a roasted malt that lowers pH, but I don't think it accounts for the pH being 0.3 points below what the equation predicts. I use a high quality pH meter that I calibrate each session, so I do not believe that is the source of the error. I keep wondering about the 5.8 in the equation. Seems like it's a big assumption. I suppose I could do the distilled water mash and see what I get. Any ideas? Thanks. - --Dave Return to table of contents
