These were 20oz "no-nick" English pub-style glasses. Needless to say, I didn't want them to get broken in shipment (via USPS for the most part.) So, I bought a bunch of 8 x 8 x 8 inch boxes, an equal number of 12 x 12 x 12 inch boxes, a roll of self-adhesive bubble wrap (12" width), and a few big bags of styrofoam "peanuts". Each glass was wrapped in a piece of bubble wrap (about 2-3 layers thick). Four glasses fit snugly into an 8" box, which I sealed. Then I poured a 2" layer of "peanuts" into a 12" box, put the 8" box in, and poured "peanuts" to fill the 12" box. I sealed and addressed the 12" box. Out of about 100 glasses shipped, one broke. The packaging cost almost as much as the shipping, though. =Spencer Return to table of contents
Date: Wed, 18 Jul 2001 04:37:23 EDT From: BShotola at aol.com Subject: separation anxiety Hello brewers, Gunnar from Montana writes: "I examined the other plants, and found that Cascade and Hallertau also have switched sexes and are now sporting male flowers! " Gunnar, this situation is uncommon in Montana, much more likely in the Bay Area, but I hate to say you seem to have somehow acquired some of those new Jim Jeffords hops. They switch over when the weather gets rough. Or maybe you have some of those Barney Franks- high bitterness, no taste, floral aroma. Steve A, in terms of the lower pH reading in your half empty Cornelius, perhaps you let a teardrop of happiness fall into the tank, thankful that your results supported your hypothesis :) Not one to have a fancy pH gizmo yet, I am just trying to keep from dropping the dang test strips into the mash, and other such blunders. Seems like each brew session offers a new way to humble myself. I don't need a beer flag flying outside my house, the neighbors know I am brewing when they see boil-over smoke roll down the hill, or my wife running. Usually I use whole flowers in my worts, so when I used some pellet hops in my last brew, I absent mindedly siphoned lots of green powder into the carboy. (My kids have a knack for bringing the dog around to see what daddy's doing just as the wort's cool enough for the infections to kick in.) I am relaxed and not worrying about the fermentation which is going strong thanks to a beautiful, huge pitch, but am now wondering how to best recover the yeast from the primary without getting too much pellet hop gook with it. Anybody give me a heads up on this? Thanks. Bob Shotola Yamhill Oregon PS. I will be passing through Albuquerque and Santa Fe next month and would like any tips on where to get cervezas buenas.

Date: Wed, 18 Jul 2001 08:10:47 -0500 From: David Sweeney <david at abacus-consultants.com> Subject: RIMS Inventor Available for Questions Greetings fellow brewers! In the spirit of Jethro Gump, I have obtained a direct line of communication with the inventor of the RIMS, Rodney Morris. For you newbies out there, RIMS stands for Recirculating Infusion Mash System. A RIMS circulates wort, during the mash, over a (traditionally electrical) heating element which is controlled by an inline temperature controller, and then returned to the grain bed. The idea behind RIMS is to create a "hassle free" mash with a high degree (no pun intended) of temperature control, greater extraction, and clearer runoff. Rodney first published an article on RIMS in Zymurgy sometime in 1989 (88?). I don't know the exact issue. The earliest reference to RIMS in the HBD was in March, 1990. Since that time, many brewers have made their own RIMS inlcluding me. Last Sunday, my brewclub held our monthly brewday out at my house. Rodney came and surveyed my RIMS system. He had lots of comments, but all in all, he thought my system was pretty good. Here's your chance. In the spirit of Rob Moline, I've gotten Rodney to agree to answer some questions about RIMS systems. But rather than post his email address all over the internet, please send your questions directly to me at the address below. I will then collect them, forward them to Rodney and then post his answers once a week until questions die down. David Sweeney david at abacus-consultants.com Return to table of contents
Date: Wed, 18 Jul 2001 10:36:24 -0500 From: "Joseph Marsh" <josephmarsh62 at hotmail.com> Subject: double crop hops&bugs Sorry can't help on the double cropping but maybe on the bugs. If the hop flowers haven't developed when you get your caterpillar invasion you can use spray with no worry about it getting in your beer. Sevin dust decomposes in a couple weeks according to the package label so you may use it early in the season. I use it on my food crops if I have to. Often with bugs you get one or two breeding cycles and you can time your spray of dusting to take out the caterpillars and not have to respray more then once or twice. That allows plenty of time for the insecticide to wash off/decompose. Alternately you can try to find something they like better then hops, try to attract birds to eat the bugs, spend a nickel on the kids. Good brewing, Joe Return to table of contents
Date: Wed, 18 Jul 2001 14:01:18 -0400 From: "Barrett, Bob (R.A.)" <rbarrett at ford.com> Subject: Stir Plate for Yeast Starter I have obtained a stir plate and plan to use it to suspend the yeast in my starter. Can someone explain how to use the stir plate from the time the yeast is added to the starter to the time the starter is pitched into the wort. I am concerned about when to start the stir plate after adding the yeast to the starter and how long the stir plate should run while the starter is growing and how fast should it run? I have a glass encased stir bar and a plastic coated stir bar. I am using a 2000 ml flask for the starter. Is there anything important as far as how deep the starter wort should be in the flask when using the stir plate. I usually make 750 ml of starter wort for 5 gal batches with on OG of 1.050 - 1.055. When making starters without a stir plate I always would be able to see activity in the form of krausen. Will this still be the case with the stir plate or will the krausen be reduced? We make the beer we drink!!! Bob Barrett Ann Arbor, MI Return to table of contents

Date: Wed, 18 Jul 2001 14:58:46 -0400 From: Stephen.F.Higdon at am.pnu.com Subject: Draft tower setup on chest freezer. This is my simple solution to the draft tower placement question. PLEASE SEE: www.hbd.org/klob/Our_Brewstands/HiggyBasement2.jpg This setup has worked perfect for well over two years now. There are 6 pressure regulators (inline), that are inside the freezer. I recently punched out a hole on the side of the tower, and added a 7th faucet, this has it's own 5# CO2 tank and dual regulator inside the chest (this 7th tap is not in this picture). The freezer is 15 cu ft, I think, and holds the 7 kegs with a little room to spare. The red hose coming out of the top left rear is hooked up to a 20# CO2 tank with it's own dual gauge regulator that supplies the in line 6 regulators. I've cut my beer line lengths to match up to the volume of CO2 I want in each of the beers on tap, (same temp, different pressures for different styles). This allows 7 individual 5 gallon kegs to be on tap at once, each with it's own head pressure and carbonation levels. The chest freezer was ~$299 at Sam's Club. The tower, drain, regulators, etc. were bought at an auction, (a nearby bar closing). Actually this is half of the setup, I sold the other half to a friend. I bought two towers (12 faucets total), with 12 regulators, a dual regulator, plus about 20 various keg taps, and many other fittings for $250. Sorry, I just had to mention that, what a great deal that was! It is like new, after a little TLC. The drain runs to a small bucket filled with CaCl2, a trick I learned from the fridge guy. It does not grow bacteria, etc, that way. The lid is a bit heavy, but the hinges have held up fine so far. I cut right through the top of the lid, insulated the gaps, and put stainless screws through. The underside of these screws are secured with large washers and nuts. A Johnson control maintains the temperature. This was an easy route to take, but works well. Return to table of contents

I found a recipe for this beer on Cat's Meow but it's called Emma Wedgewoods Ale or some thing like that. It was a partial extract, which sufficiently challenge me and it was my firts BIG BEER. I read the SG as 1.085 and calculations put it between 1.081 and 1.073, depending on whose numbers I used. I've had trouble bringing the beer to attenuation. It's been in the fermenter for about seven weeks. It's been racked 3X so it's not sitting on any solids and I had it at too low a temp for a couple weeks. You can follow the thread at http://hbd.org/forums/. Go to "The Brewerys Views and Nrws" and look for the "Stuck Ferment" thread. Here are the ingredients: 7.5 lbs. British Pale DME 1.0 lb Pale Crystal 2 oz Roasted Barley 1 lb Clover Honey 2 oz Malto-Dextrin Powder 1 oz Fuggle plugs (boil) 1.25 oz Bullion pellets (boil) 0.75 oz E. Kent Golding pellets (flavor) 0.25 Bullion pellets (flavor) 0.5 oz E. Hallertauer pellets (aroma) 0.75 oz E. Kent Golding pellets (dry hop) White Labs Claifornia Ale yeast WLP051 The hop schedule is kind of tedious but I'm looking forward to tasting it as the interim samplings have been very good. I suggest you look for the recipe on Cats Meow. There may be some others that are all-grain in there as well but since I'm not there yet I didn't pay much attention. Let me know what you find.

Date: Wed, 18 Jul 2001 21:58:17 +0200 From: Hubert Hanghofer <hhanghof at netbeer.co.at> Subject: Re: Krausening Hi all, Jeff Renner wrote in HBD#3687: > Kraeusening is traditionally done to beer that has finished lagering. This is new to me ...but one never knows, do one? ;-) I can see that this could work but actually (at least today - in Bavarian breweries that I'm familiar with) krausening is done before lagering - right after the beer is close to final gravity in the primary. 10-15% krausen is common for lagering tanks with adjustable pressure relief valve. If you don't are equipped for this carbonation method (aka. "Spundung") and need to do closed carbonation (bottle conditioning) you'll either need lots of experience and instinct or you apply some calculations. Following chart will give you details. It's quoted from my German book and should be readable with a fixed width font: var unit notes and formulas - ------------------------------------- K Plato apparent extract in krausen D g/cm3 Density = 261.1 / (261.53 - K ) T Plato expected terminal extract (apparent as measured with saccharometer) F g/L concentration of fermentables in krausen F = (K-T) * 8.192 * D ===================== P g/L required priming rate (fermentable sugars per L beer) Qb L quantity of green beer that needs to be primed Qk L required quantity of krausen Qk = Qb * P / (F-P) =================== This "krausen-formula" results from solving following equation: (Qk + Qb) * P = Qk * F The left and right side of the equation each give the total quantity of required fermentable extract, ok? UNITS: L = Liter, Litre g = grams Density (20/4) = SG (20/20) * 0.9982 (...ok: that one should be neglible) 8.192 is the "Balling-factor" and corrects the effect of alcohol on saccharometer readings. You best understand it this way: If the saccharometer reading drops by 1 deg Plato, 0.8192 % of extract have actually been fermented. I assume you're familiar with the calculation of the required priming rate (P). -Don't forget to take into account CO2 saturation at green beer temperatures and -if still present- any residual fermantables in the green beer. The same calculations can be applied with wort-priming, aka. priming with "Speise". hope this helps Hubert HangHoFer ^ ^ Salzburg, Austria, EU www.netbeer.org Return to table of contents
Date: Wed, 18 Jul 2001 15:10:15 -0600 From: "Richard B. Dulany Jr." <RDulany at co.el-paso.tx.us> Subject: dishwasher-free sanitizing Regarding the recent posts on dishwashers and bottle cleaning: Has anyone tried the old winemaker's method of rinsing your visually clean bottles with a 10% potassium metabisulfite solution immediately before bottling? Will it adversely affect the taste or head of beer? It works great on white wines, but then I usually want to raise the free SO2 level of the wines slightly at bottling anyway. Just wondering if this is a bad idea for beer. Not everyone has a dishwasher. Ricardo Return to table of contents
Date: Thu, 19 Jul 2001 00:07:30 +0200 From: Hubert Hanghofer <hhanghof at netbeer.co.at> Subject: Re: pH measurements Hi all, It's possible to measure pH with a reproducibility of less than 0.02 - but only if you know about all the pitfalls and take care of them! If you don't, you may soon find your values far off (say more than 0.1, maybe 0.2) even if using a high end pH-meter, while another tester using simple equipment but paying attention to the pitfalls will be in the right ballpark! So -for example- to achieve reproducibility of less than 0.02, it's essential to keep the temperature difference between measurement and calibration within 0.1 deg Celsius (eg. calibrate and measure in the same tempered water bath)! A temperature compensated pH-meter WON'T help you here! Why? Temperature compensation is probably the most misunderstood feature and thus causes many errors - IMHO even in "more or less" scientific publications. Let me try to explain it this way (partially quoting WTW's pH-primer): A pH-meter can only measure a potential difference - a voltage - generated between two electrodes, one of which is sensitive to H3O+ The measured voltage has a linear dependency on the pH value and is converted by means of calibration data. BUT: The slope of the corresponding straight line curve is temperature-dependent. A change of the pH value by one unit results in a voltage change of 55.19 mV at 5C 59.16 mV at 25C or 63.12 mV at 45C It's only this change in sensitivity that can be compensated, NOT the pH! There's no way for the pH meter to know the pH / Temp characteristics of a certain medium. But shouldn't temperature compensation work when calibration and measurements are carried out at different temperatures? In theory yes, BUT: There's another pitfall: Offset voltage! Ideally, the electrodes should give 0 mV at pH7, in practice this is never the case. As well as the slope, the offset voltage is also temperature-dependent. The influences that are causing offset voltage are, however, so complex that compensation is NOT possible! And that's the reason why you should calibrate at measurement temps. Remember we are talking about 0.02 reproducibility. If you round off to 0.1 it gets easier but I still wouldn't calibrate off more than 5C. I don't want to torture you any further with my sloppy English. I've *temporary* uploaded a pH-primer from WTW for those of you who want to know everything about measuring pH - including all the pitfalls! http://www.netbeer.co.at/beer/bin/ph_e.pdf File size is 1006kB. If someone finds this primer useful and owns the resources to host it permanently - please contact www.WTW.com to ask for permission. I think it's shareware but don't know for sure. Allzeit gut Sud!

Date: Wed, 18 Jul 2001 16:13:18 -0700 From: "Hedglin, Nils A" <nils.a.hedglin at intel.com> Subject: Boiling Pot/Liquor Tank & Brewing with Plums Hi all, Two of the things that're keeping me from trying all-grain recipes is the worry about getting & keeping the water to the right temperature for the mashing & sparging, & only having a 5 gallon boiling pot. My mash/lauter tun is a very nice one from Hobby Beverage Equipment, & they have a Hot Liquor tank, but buying something just to keep water hot seems to be a bit too much specialization to me. I'm also worried about the affect of the high water temperatures on the racking tubes & canes. Then I had a brilliant idea that might solve both problems. If I buy a boiling kettle with a valve at the bottom, then I could us it as a hot liquor tank, then turn around & use it for the boil. Having only done 1 all-grain so long ago I don't remember the process, will using the pot for double duty work? Or will I need to be collecting the run-off into the boiling pot at the same time I need to for the sparge? The summer fruit crop must be starting to roll in since everyone at work bringing in loads of extras they want to get rid of. One person has so many plums she can't get rid of them fast enough. I was thinking about trying a plum brew. Has anyone else brewed with plums? What flavor profiles would make a good flavoring plum? For that matter, what kind of base beer would I use? From my general reading, I know that it would probably be best to add the plums during secondary fermentation, but how much for a 5 gallon batch? Since the plums were grown in a backyard, I'm pretty sure they're relatively free of pesticides, but are they other concerns in using fresh fruits in brewing, like wild yeasts, naturally occuring bacteria, etc?
