I plan to bring several electrical appliances with me back to the States (also Chicago). I know the American standard for 220 Volts is provided by combining (2) 120 volt legs 180 degrees out of phase. This trick requires a 3 prong plug (2) hot wires and (1) common. My European appliances are wired for single phase 220 Volts (1) Hot and (1) common. How can I connect them to a 3 prong outlet for service in America? Wayne C.

Date: Tue, 02 Jul 2002 09:09:27 +0000 From: steve-alexander at att.net Subject: many things Pete Calinski speculates on a refractometer reading given alcohol in the solution, but his definition of Plato ... 'Plato' *ONLY* represents a relationship between the amount of *cane*sugar* extract as a %weight (mostly sucrose) in solution vs the specific gravity(SG). When we apply the term Plato to wort or beer we are in a state of sin. Only cane sugar solutions accurately follow Plato scales. Wort extract is 80% carbs, 65% fermentable and only a few percent of that is sucrose, much of the rest is protein & amino acids etc, but the Plato extract is probably close enough to wort extract (w/in a few %) for a given SG to permit the use of Plato as an approximation. When we write that a certain wort is P% Plato what we really mean is that it has the same SG as a P% Plato cane_sugar solution. We don't know the relationship between P% and the true wort extract% - but it is not exactly 1-to-1 and it varies from wort to wort. Measuring instruments that float to a level in wort/beer are using Archimedes principle to measure *density*. Density & temperature will allow us to *approximate* SG. With SG and a Plato scale we can *approximate* wort extract % from SG. The error is modest for wort, but is very inaccurate (unusable) for beer. The "Pros" use the Plato scale and so do pro journals, but the reality is that density is all we really know from any floating instrument. Given SG and FG we can approximate %alcohol or the % remaining_extract, but this requires assumptions about the wort extract type, fermentability and the efficiency of the yeast conversion and use of carbon for yeast biomass. They are good approximations and nothing more. Refractometers measure light refraction and nothing more. Most refractometers come with a scale that relates refractive index to Brix, Balling or other scale similar to Plato. The Brix scale only applies to the Brix standard solution (sucrose ?) and not to wort or to beer. It may give a reasonable approximation of wort extract (cruder than a Plato hydrometer I think) but a terrible one for beer. - -- The shift in index of refraction is about 2.5% greater for maltose than sucrose, and greater yet for higher higher dextrins. Proteins&amino acids cause a much greater IofR shift (~1.5 times greater than sucrose) and alcohol a more modest shift (less than half the sucrose value). A 5% ethanol solution gives a similar IoR reading as a 2.1% maltose solution, so beer IoRs will read a few Brix high, while Beer SGs will read several Plato low compared to the amount of carbs left in the beer. The ethanol in beer can be accounted by either method, (hydrometry or refractometry)but it's complex and approximate. >they have >refractometers at a good price. A refractometer with crummy optics is never a bargain so check out the return policy or find a review of the refractometer. ============================= Paul Kensler writes ... boil time and wort composition >Someone recently told me that boiling for 90 minutes >vs. boiling for 60 minutes would make for a less >fermentable, fuller-bodied beer. There will be a microscopic reduction in fementability and a corresponding difference in body under normal circumstances. A *tiny* additional amount of wort sugars form caramel and maillard products during the additional boil. It will probably not be noticable by anything other than a chromatograph. >Will the 90 minute boil wort be ><significantly differant than the 60 minute boil wort, >as far as fermentability, body, mouthfeel, flavor NO! Except the longer boil may reduce DMS levels noticably in certain lager malts. ========== David Mackaway writes ... re: US Electrical System - 240V >Can anyone explain to me the electricity setup in the >US. Homes in the US get 240vac, but the 240vac transformer (at the street or nearby) has a center-tap. The center tap line is called 'common' and either of the ends are referred to as 'hot' wires. The voltage between the two hot wires is 240vac at 60hz. Between either hot wire and the comoon it's 120vac at 60hz. Most of the circuits from the breaker box carry 120vac (one hot wire and the common) to standard outlets, plugs, lighting etc. High power devices (electric clothes dryers, electric ovens, air conditioners ... ) have the full 240vac circuit routed (two hot wires). 240 circuits require a 240vac breaker be placed in the breaker-box which connects to both of the 120vac hot lines. A third wire representing an earth ground is also routed to all modern sockets & 240vac circuits, but not to lights or older style (pre 1960s) outlets. The earth ground design permits the use of ground-fault-circuit- interrupter(GFCI) sockets which are often required in kitchens, baths, basements. You can also obtain GFCI- breakers for some makes of breaker-box. GFCIs break the circuit if there is any current mismatch in the two current carrying wires (for example if you are being shocked). GFCIs add considerable to the price (maybe $15 extra for a 120vac socket pair and $40 extra for a breaker) but are a good idea in a brewing situation. If you are handy with electricity you can get all the required parts for adding a 240vac brewery circuit at most hardware stores. There is sadly no US standard 240 plug&socket receptical design. There are 3&4 prong connector pairs comonly used for ovens & dryers, but these are awkward to connect/disconnect. I prefer the round 3 wire twist- lock type for my 240 power tools. -S Return to table of contents
Date: Tue, 2 Jul 2002 04:14:56 -0500 From: "Louis Bonham" <lkbonham at houston.rr.com> Subject: More on SG and alcohol Pete raises a couple of other points: >I tried to use the posting from 7 Jan, 1999 before I posted the original on the subject but I couldn't get it to match ProMash. Assuming you meant the formula I posted on Jan 9, 1999, there was a typo in it (corrected in the Jan 12, 1999 HBD). And there will be a bit of slip between that formula and ProMash because in ProMash we were able to use the full version of the various underlying formulas rather than the truncations I used in coming up with the "pen and paper" formula. As far as Pete's suggestion about coming up with "calibration" solutions of sucrose and isopropyl alcohol, I don't think this will get you anywhere. (If you want to use something as a calibration solution, use Bud or Coors . . . don't laugh, the ABV and SG of these beers are readily available, and their QA/QC tolerances are probably smaller than most of our measurement errors!) Even assuming that isopropyl alcohol has the same RI and SG as ethanol, as noted before beer has lots of other stuff in it with varying refractive indices. For this reason, the various refractometry formulas (e.g., Berglund, Emlington, and Rassmussen regression equasion cited by DeClerck) were derived from empirical data (SG, ABW, RI) from lots of beers . . . and even then, the confounding affect of these other substances affects the utility of these formulas. I'm afraid this is kind of like the search of the "perfect" IBU formula . . . it's just not there. These kind of formulas are pretty good at estimating things, and may be "good enough" for our purposes as amateur or small scale brewers, but because of the complex nature of beer they'll just never provide the kind of accuracy that one associates with quantitative lab assays.

If boiling removes water, then longer boil times will translate into higher SG, and higher concentrations of non-fermentables which contribute to mouth feel, head retention as well as sweetness and other flavor components. At 1.5G/H evaporation rate, you should loose .75 gallon additional water. The question is, is this accounted for. If the specific gravity of the wort (post boil) is the same in both cases, then this is a null statement.

Yes. The starches of corn and rice do not gelatinize and become available to the amylase at mash temperatures the way raw barley, wheat and rye do. To cook, add about 30% malt ("premalt) (that's 30% of its weight, not 30% of the malt in the recipe), mash for 20-30 minutes at 153F or so, then bring to a boil and cook for about 30 minutes for cornmeal or broken rice, longer for grits or polenta. Then add to your main mash, which you have already mashed in at a proper temperature to accommodate the heat of the cereal mash for the next step. Be sure to use plenty of water for the cereal mash, and adjust the minerals as you would for the main mash. This means low alkalinity for a pilsner. 1.5 quarts per pound is not too much. I mash in an 8 qt. pot in a preheated oven at mash temperature, then bring to a boil and cook on the electric stove with a trivet or heat diffuser between the element and the pot. This helps prevent scorching, but you still need to stiff frequently until you establish a boil and can turn the heat down to a simmer. I just brewed a CAP yesterday for our daughter's wedding in August. It was 95F outside and hotter in my garage with the burners going. I used the mash schedule I have settled on - mash in at 145F, rest for 30-45 minutes while boiling the cereal mash, add the cereal mash, which brings the combined mash to about 160F (you may need to add so boiling water or heat), and rest another 30-45 minutes. This produces a wort with high fermentability for a crisp pilsner. Be sure to use degermed cornmeal, not whole corn meal, which has the oily germ present.

Date: Tue, 02 Jul 2002 09:04:30 -0400 From: Jeff Renner <JeffRenner at comcast.net> Subject: Re: Gypsum & Bottle Chilling Nils Hedglin <nils.a.hedglin at intel.com> or Sacramento, CA writes: > I made some oatmeal stout last week & since we have a water softener, I >was going to add some gypsum. Unfortunately, I was almost at the end of the >mash when I realized I didn't know when to add it. Should it go in the mash >liquor, or in the boil? I'm assuming the former, but added to the boil just >in case. Several things here. First, the water salts do generally go in the mash to provide calcium ions to aid in the achieving the proper pH for conversion. But with a stout and the acidity of dark malts, this is not as important as with a pale beer. It depends on the alkalinity of your water. Now to another item - you say you have a water softener. I assume that you also mean that you used the softened water for the brew. While it might not have caused a problem, especially in this brew, it's not a good idea to brew with softened water. An ion exchange softener replaces each calcium and magnesium ion with two sodium ions and leave any alkalinity unchanged. so you are removing the desired calcium ions and leaving the generally often unwanted (at least for pale beers) alkalinity. Finally, a style consideration. The sulfate in gypsum (calcium sulfate) is generally considered to accentuate the dry bitterness of the hops, and oatmeal stout is a softer, less dry stout. I don't think I'd use gypsum for it. In general, you should add water salts to brewing water based on a reason, not just a recipe. Recipes don't often take into consideration the differing natures of brewing waters. For oatmeal stout, I would think you'd want sufficient calcium for mashing (50ppm or greater), sufficient alkalinity to balance the dark grains, and low sulfate. You might not have needed to add anything. Of course, in the end, you beer will likely do fine. Beer wants to be made. Don't worry, let us know how it turns out and we'll add to the body of knowledge. > Also, I vaguely remember reading somewhere that if you chill a bottle of >beer too fast, it might gush. Is this true? No reason I can think of for this to be true. The CO2 in the warm beer is at supersaturation, but it's still in solution. When the beer is colder, it can hold more CO2, but it won't take any time for it to achieve greater solubility. >I had batch of brown ale that >I bottled last week, in a room that was about 80 degrees. I stuck it in the >freezer for about 30 minutes & when I opened it, it gushed out all over. >I'm really hoping it's not contamenated or that I over carbonated it. What's more likely is that it wasn't thoroughly chilled in 30 minutes and it gushed because the beer couldn't hold as much CO2 as it could if it were colder. If it doesn't taste infected, it probably isn't. Of course, it may be overcarbonated. Let a bottle chill in the fridge a day and see.

I have since fitted the kegs and have been actively brewing with them for the last year. Are these Kegs stainless? I assume yes, as the shavings from when the tops were removed did rust just a bit before I cleaned and ready the kegs for duty. What grade of stainless are these Kegs? I'm sure the keg makeup is common to all AB kegs, rather than regional in nature. So, I'm assuming again that all AB kegs are stainless. It must be a simple question for the individual with the right knowledge, of which I'm sure resides somewhere within the HBD. Ps. I checked the archives before posting,,,I hope the questions are not redundant.

To use Steve's example of OG=1.0483, or OP=12, I could make a >solution of 13.6 mg of sucrose in 100 ml of H2O. That would yield: Watch your units. A 13.6 P solution has 13.6 GRAMS of sucrose in 100 grams of solution, or 1.36 grams of sucrose in 10 grams of solution, etc. That is, one milliliter of pure water at 4 C weighs one gram. I've been using a refractometer in brewing for a few years and once the refractometer is calibrated with a reference solution it agrees to within 0.001 with my hydrometer on my wort samples. I suppose my hydrometer could be off, though I know it is accurate at 1.000. So, the first thing you need to do is calibrate your refractometer(s) with known sucrose solutions, and calibrate your hydrometer. You may want to use Everclear (ethanol) instead of isopropanol. If you can't find Everclear, try some 151 rum. Adjust your solutions for the proof - 1 proof = 0.5% ABV. Since there is much more glucose (dextrose) in wort than sucrose you may want to use corn sugar (dextrose) rather than table sugar (sucrose). You could probably devise a way to use CliniTest to determine the glucose to sucrose ratio :-) It might be interesting take a known weight of wort and evaporate all the water, weigh the residue, then make a standard solution with the residue and test for glucose content. If you assume that ALL the residue is glucose and sucrose, you might get a good idea of the glucose to sucrose ratio. Of course it is wort specific. >How can I get a handle on how much this method is in error? My guess is that there is NO LESS eventual error in your method than in just using a calibrated refractometer and calling it good.

Date: Tue, 2 Jul 2002 20:41:03 -0500 From: "Louis Bonham" <lkbonham at houston.rr.com> Subject: "Boycott the AHA" -- Five years later (Part 1) Greetings all: With all the well-deserved raves about the recent AHA National Homebrew Conference, I think it is appropriate for us to reflect on how far the AHA has come in the past few years. (The following thoughts are mine in my individual capacity, and do not necessarily reflect those of the AHA, its Board of Advisors, or anyone else.) Long-time denizens of the HBD will recall that five or so years ago, I was one of the more vocal critics of the AHA in this forum and in r.c.b., and goodness knows there was plenty to criticize. The organization had become totally out of step with most homebrewers, Zymurgy had become a very bad joke, and member/customer service was awful. NHC's were being run "top-down" by the AHA, which engendered lots of grumbling from the local clubs who did most of the work. There was an AHA Board of Advisors made up of various appointed amateur brewing luminaries, but from most accounts it was a token entity that the AHA bureaucracy could (and usually did) ignore. Many of the shots out of Boulder were being called by a non-brewer who attempted such ill-advised moves as trying to replace the BJCP and Home Wine & Beer Trade Association with AHA-associated and controlled organizations, which didn't win the AHA any friends. At one point the AHA tried to run the HBD, and did such a horrid job that it very nearly died (but for Pat Babcock and Karl Lutzen riding to the rescue, it would have). Meanwhile, Charlie Papazian was seeing his salary increase to stratospheric levels, while appearing to be spending most of his time on extended world-wide pub crawls on the AOB/AHA dime. Many aspects of the AOB/AHA's finances appeared suspect, but management refused to allow members to see even basic records such as IRS Form 990's (by law, these were supposed to be made available on request to the general public). Worst of all, there was no democracy whatsoever in the AHA, and thus there was nothing AHA members could do about these problems except quit - -- which they did by the thousands. Fast forward to the present. Thanks to a lot of genuinely hard work by Paul Gatza and what is for the most part a new crew in Boulder, the ship has been righted. Ray Daniels has brought Zymurgy back to being the premier amateur brewing magazine. NHC's are now run by local clubs with the assistance of the AHA staff, with spectacular results. In response to member suggestions, there are many programs in the pipeline to provide more value for AHA members, such as the Pub Discount program, a member discount program, the Lallemand Scholarship, student/associate MBAA and ASBC membership opportunities, and creation of a speakers bureau for local clubs to tap. The former imperial "AHA only" tone from Boulder is gone, with the AHA now actively and genuinely reaching out to work with other organizations to assist their efforts to promote amateur brewing (e.g., MCAB and the BJCP).

Date: Tue, 2 Jul 2002 20:41:20 -0500 From: "Louis Bonham" <lkbonham at houston.rr.com> Subject: "Boycott the AHA" -- Five years later (Part 2) [post continues] Democracy has also come to the AHA. The voting members of the Board of Advisors are now all elected by the AHA membership, and include several former AHA-skeptics such as myself and Pat Babcock. The Board meets year-round by e-mail, and the the AHA staff in Boulder takes their advice seriously (indeed, many of the programs coming out arise from Board of Advisors suggestions). AHA members also now have a genuine voice in the running of the business affairs of the AHA *and* its parent organization, the Association of Brewers, by virtue of the fact that three members of the AHA Board of Advisors sit on the AOB Board of Directors. (FYI, the AHA BoA members currently serving are Dave Houseman, Alberta Rager, and as of last month, yours truly. The craft brewers' arm of the AOB, the Institute for Brewing Studies, similarly now elects three of its member-elected advisors to the AOB Board.) Charlie's salary and travel issues have also been addressed, with Charlie voluntarily taking *very* substantial pay cuts, curtailing his trips (which are now subject to Board of Directors oversight and approval), and from most accounts Charlie is now taking a much more active role in running the day-to-day affairs of the AOB. Five years ago, I issued a call for people to boycott the AHA until it changed its ways and became the kind of organization that deserved our support. I think the AHA has reached that point. While the AHA isn't perfect -- there is still work to do -- I firmly believe that the changes are real, that the bulk of our criticisms have been or are being addressed, the structures for member-driven improvements are in place . . . in short, we've gotten just about all of the things we wanted, and the AHA now deserves our support. Thus, for you AHA-bashers out there, perhaps it's time to declare victory and move forward. For those of you who have never been AHA members, I ask you to consider joining -- both for the benefits of being a member and to help us promote beer appreciation and the craft of amateur brewing. For those of you who used to be AHA members, I ask you to take another look -- it's *not* the same organization we all used to know and, shall we say, not love. All the best -- Louis K.

By passing along your knowledge you have helped me. and numerous others to brew better beer. I myself started brewing back in 1994, brewing extract batches. And since then have gone to all grain, or extract with partial mash brewing (depending on the recipe and time available). The knowledge a home brewer can be exposed to here at HDB has done more to improve my brewing skill than anything else. For new brewers I would tell them the same things I learned either here (From fellow brewers in HBD) or on my own. 1. Mr. Beer type kits suck, they brew god awful beer. 2. If you brew extract brews use DME not liquid extract. 3. If you want better beer, move up to partial mashs, or all grain. 4. Keep brewing and improve your recipes / beer. 5. You have to be drinking a home brew when you are brewing or the beer gods get pissed and make things go awry.

IN HBD #3978 Aaron asked for help with using a digital thermostat (for a 'son of ferm' chiller): "The Thermo has 4 terminals marked R, W, G, Y R-power in W-Heating and Heating damper Y-AC and AC damper G-Fan When I connected a wire from either AC terminal on the adapter to the R terminal on the thermo...Nadda!!! Any ideas??" Aaron, You didn't mention the make and model of thermostat. But since it (from your description) doesn't have a C (common, sometimes labeled BK for black) terminal, it is either battery operated, which shouldn't be too hard to figure out;), or it is a "power stealing" model. For power stealers, the circuit is completed once you connect the R (red, or power) to one of the transformer terminals, the Y or G to one fan wire, and the other fan wire to the remaining transformer terminal. The thermostat uses milliamps, and the fan will pass this current without actuating. When your stat calls for cooling (or heating, you can hook up a heating element through a relay to the W terminal) full current flows through the fan to operate it. With the fan connected to Y, it will only operate when the stat calls for cooling. Connected to G, you can also manually switch it on using the Fan key on the stat. If you use thermostat wire it will help simplify wiring. Check the current requirement on your computer fans, make sure the two of them don't overdraw your transformer.
