---------------------------------------------------------------------- Date: Thu, 17 Aug 95 13:09:00 MST From: "Fleming, Kirk R., Capt" <FLEMINGKR at afmcfafb.fafb.af.mil> Subject: Wort Dilution Simplicity Dumbfounds Reader What was obvious to John in his post yesterday was not at all to me. He made the calculation so simple that I couldn't see why it worked. Sometimes I feel like the Beavis of the brewing world. It did work, or course, and inquiring (if simple) minds wanted to know. I started with: final wort weight = original wort weight + added water weight then express this in terms of gravities and volumes instead of weights: final wort weight = d2v2 [final dens * final vol] original wort weight = d1v1 [orig dens * orig vol] added water weight = (1)(v2 - v1) [dens of water = 1, added vol is v2 - v1] d2v2 = d1v1 + (1)(v2 - v1), OR simply d2v2 = d1v1 + v2 - v1 (1) Now, collect like terms: d2v2 - v2 = d1v1 - v1 and factor v2(d2 - 1) = v1(d1 - 1) (2) Since the gravities dn can be expressed in points pn = 1000(dn - 1), replace the "dn - 1" with dn - 1 = pn/1000 in Eqn (2) above: v2(p2/1000) = v1(p1/1000) (3) Multiply both sides by 1000 to get v2p2 = v1p1 (4) *This* should be an easy one to remember! Rearranging to comply with the problem as first stated (how much water do I add to get gravity p2?): v2 = v1p1/p2 for the final volume, or for the amount to ADD, v2 - v1 = v1(p1/p2) - v1 = v1(p1/p2 - 1), that is, --------------------------------------------------------------------------- vol to add = (orig vol)*(orig points/final points - 1) (5) --------------------------------------------------------------------------- Which is exactly what John already said--he just didn't make it sufficiently complicated to earn maximum AI Robot "HBD Worthiness Factor" points. I earn negative points for repeating it, however. I know I can't declare the thread dead, but I'm sure everyone agrees we now have it bleeding rather badly!

One article posted either here or in rec.craft.brewing from a well respected source (I think it was Geo.Fix, maybe Al Korzonas(sp?)) earlier this year discussed the possibility of performing cold sparges and still getting excellent extraction efficiency. You may be losing points in the sparge but I have some doubt that it is from the viscosity difference of wort between say 158F and 168F. When I switched to all-grain brewing early this year, I consistantly experienced mediocre extraction efficiencies of 77% to 84% and have always done a mash-out. I have tried many technique and apparatus changes and just recently have gotten my efficiency up. The efficiencies on the last four batches were 92%, 94%, 93%, 97% for an American ale, dry stout, Wit and an IPA resp'y. These represent very different malts and grains, mash schedules and two different sparge devices. The consistant factor in these cases is that I crush the malt & raw grain finer than the so called textbook crush. I use Schmidlings adjustable maltmill(tm) set on the finest setting. This still leaves many husks intact but breaks most grain bodies into many parts. I've had no unsual difficulties sparging this fine crushed malt using either slotted 1/2" copper tubing, or a copper screen wrapped over the end of a tube. I also increased my sparge time from around 45' to 80'-120' ! So I guess my suggestion regarding efficiency is: crush fine, sparge long.

It's a mixture of Beer and Lemonade. There's a similar thing I had in London called shandy, but I've only had poor ones in cans. I made some myself before I became a brewer. If I remember, it was about 2/3 beer and 1/3 lemonade. I'd think you would want to use a lighter beer in the mix, and I prefer real lemonade to a powder, though I'm as lazy as the next guy. Dunno about brewing it directly.

Date: Fri, 18 Aug 1995 07:30:16 +1000 From: david.draper at mq.edu.au (Dave Draper) Subject: Dilution even simpler / Alc. lemonade Dear Friends, like John Palmer, I too have been highly bemused by the level of detail brought to bear on the question of calculating dilution. In #1810, John outlined a simple procedure and asked: "What could be simpler?" Well John, the answer is this: the ratio of the volumes involved (pre- and post-dilution or -concentration) gives you the factor by which to multiply the gravity, *in gravity points*, and the ratio of the gravity points gives the factor by which to multiply the volume. No need even to calculate the product of volume and gravity points (e.g. the 7 gallons of 42 ppg = 294 John cited). Several issues ago, someone (I'm sorry I did not record your name) posted just this but it seems to have been overwhelmed by the more elaborate approaches--so let's see it again: So we have 30 litres of 1.042 after sparging and know we will end up with 23 litres after boiling. We know the gravity will go *up* because we are concentrating, so we make sure to arrange the volumes so that the ratio is greater than one, so that when we use it to multiply the gravity, the result will be higher than what we started with. So 30/20 = 1.5; 1.5 times 42 = 63; so we know that our 23 L will have a gravity of 1.063. So we have 3 gallons of a 1.070 wort and want to dilute it to a new gravity of 1.050. How much water to add? We know the volume will go up, so we arrange the gravity point ratio for >1, namely 70/50 = 1.4. 1.4 * 3 = 4.2, so the diluted volume will have to be 4.2 gal, meaning that we need to add 1.2 gallons to our original 3. So we have 13 L of 1.060 wort, and we accidentally pour 10 L of water in. The gravity has to go down, so the relevant volume ratio is 13/(13+10) or 13/23 = 0.565. 0.565 * 60 = 34 so our beer is ruined (since we were trying to make a bock) at a gravity of 1.034. Doesn't even matter what volume units you use, SI or SCBE (screwed-up British engineering) (thanks for the fat pitch Kirk, sorry I couldn't do any better than a piddle up the middle). ***** John Girard (through sprmario at netcom.com) asked about the alcoholic lemonade made here in Sydney. It's called Two Dogs, and is made at the Lord Nelson brewpub. Our club had a meeting there and post-meeting tour of the brewery, and as I recall the procedure for Two Dogs is very simple--lemon juice, heaps of sugar, and Whitbread ale yeast. Not to my taste, to be honest. If you want to try such a thing, probably a frozen lemonade canister is a good starting point rather than powdered stuff like Country Time (haven't been in the US for awhile, don't remember if CT is frozen now too). Make a small batch, add some sugar (I really have no idea at what rate, but you can just measure the gravity till you get a reasonable OG), boil for a few minutes to kill the Alien Lifeforms, chill, and pitch a rehydrated pack of Whitbread. Once you get something you like you can scale up to a larger batch, maybe use a liquid yeast, etc. Good luck.

Date: Thu, 17 Aug 1995 18:33:44 -0500 (CDT) From: Sylverre Polhemus <sylverre at tyche.lib.utexas.edu> Subject: Alcoholic lemonade John Girard (through sprmario at netcom.com) asked about high-alcohol, effervescent, alcoholic lemonades. Information comes, but first, one question: what does Country Time have to do with lemonade? Last I chescked, there were no lemons in those cans. Check the cat's meow files: there's a pretty good lemon cider recipe, and a recipe named something like Yuppie Guppie's Alcoholic Lemonade, which might be what you're looking for. Also, look under the historical drinks -- there's a recipe for lemon beer that's kind of fun. If you follow the recipe for lemon beer, you end up with a very low alcohol, highly fizzy drink. If you leave it alone for a week or so, you end up with a somewhat fizzy, higher alcohol potable. If, however, you let it sit for about two weeks, prime it, and bottle it, you end up with an effervescent, moderately high-alcohol (sorry, no % available at present), quite lovely alcoholic lemonade. It also makes a fantastic gin-and-lemon-and-tonic type concoction, if you add juniper berries after letting it ferment for a week. Enjoy! He was mead in the yeast, drunk in the eye -- altogether a sot for sore wines. Sylverre at tyche.lib.utexas.edu Return to table of contents

You certainly have helped. Next question. This evening, I placed one tablespoon of iodophor in my *brand new* keg (splurged). I dribbled some on the throw-run in front of the sink. After I gathered-up the rug, I filled the keg with cold water, sealed it and left it while I had supper. Then, half an hour or so later, I returned, inverted the keg and left it for ten minutes or so. Came back and drained it. Some brown "drips", a dozen or so, have formed on the inside bottom of the keg. The sides are clean. Some of the drips seem to originate at the ss weld where the bottom is connected. I tried rinsing with water, scrubbed a little with my carboy brush. Nothing. Still there. I had intended to keg my stout this eve. What is this stuff?. Is it safe to keg? I knew that iodine would stain, but stainless steel? TIA Fr. Bradley A.M.

Date: Thu, 17 Aug 1995 19:34:55 -0700 From: scarin at primenet.com (Larry Scaringelli) Subject: converting kegs, pre chiller First I would like to thank you all for the wealth of information in the HBD. I have been receiving the HBD since May and have learned more from the collective wisdom then any other source, as well as great gadget ideas. I have recently come across two kegs that I would like to convert to start to build a tier system for the eventual plunge into all grain brewing. I am concerned as to whether they are SS or not. They are from that lovely mega brewer in Colorado( No I didn't drink the swill within they were given to me). If any one has any first hand knowledge or a way to check I would appreciate a reply. E-mail fine. In addition living in Arizona my tap water at times is very warm probably in the 80 degree plus range especially in the summer. I was trying to come up with way to use a chiller that would work in the heat and I came up with the following idea. If it has been presented before I apologize but I haven't seen it. My thought was to run copper tube in a tight spiral through a 1 to 1 1/2 foot piece of 2" PVC pipe cap both ends with holes drilled for the copper tube and holes drilled into the top of the pvc. attach quick connects to the ends of the copper tube on bothe sides one male one female. Meanwhile in the inlet line of the chiller hose cut it and install a quick disconnect of the same type and size as on the "pre-chiller". Fill the prechiller with water and freeze. Once you have acheived the initial rapid tempature drop to the 90 degree range stop the water and install the "pre-chiller" with the disconnects. Restart the water flow. The "pre-chiller" should cool the tap water as it flows through and allow you to continue to chill the wort to pitching tempatures. All of the above is theory with no sound scientific backing or feasibilitry studies. It is based on my common sense or lack therof and what I have read in the HBD. Any and all feedback appreciated Email is fine I will post summary and results if tried. TIA for feedback.

Date: Thu, 17 Aug 95 20:52:51 -0700 From: John Glaser <glaser at widlar.ece.arizona.edu> Subject: Hunter airstat diodes/Stainless fermenter Hunter Airstat Diodes: Lee spoke about replacing the 24V, 5W zener diode in the Hunter Airstat. *If* this diode is used simply for voltage regulation (and it probably is), try replacing it with 2 12V, 3W zeners in series. You will effectively have a 24V, 6W (approximately) Zener by doing this. I have not tried this on a Hunter Airstat, I do not guaruntee anything at all. (I have used this method in other circuits successfully). If the above is not clear, you shouldn't try this without adult supervision. Otherwise, hack away. DO NOT use two 24V, 3W diodes in parallel. If they are not well matched, the lower voltage one will blow. If it blows open, the second one will follow shortly. Stainless steel fermenters: If you are expanding your batch size, consider using 10 gallon soda kegs as fermenters. I found one at a local junk yard for $20 in good shape. They arethe same height as standard soda kegs, but have a 12" diameter. I think St. Pats has them for $45. Works great, has handles, won't shatter, easy to clean (you can get your hand in it or at least I can). I had planned to use a cut-off keg as an open fermenter, but I couldn't put it in my fridge and still shut the door. I can fit this in my fridge, along with one 5 gallon carboy or two 5 gallon soda kegs. John Glaser glaser at ece.arizona.edu Return to table of contents
Date: Thu, 17 Aug 95 17:56:20 CDT From: korz at pubs.ih.att.com (Algis R Korzonas) Subject: trip report - part 2 Here's part 2 of my Germany-Belgium trip report. * Hanssens, I feel, makes the best Kriek. Their Geuze is variable, from good to excellent. One bottle I had tasted very oily/solventy/caprillic. While this can be part of the style, I thought the levels were excessive. No year on the cork, so it was impossible to tell how old it was. Another bottle at a different cafe was much better. * I was not happy with the Girardin Geuze or Lambik I tasted. Neither were as good as the Cantillon, 3 Fonteinen or Hanssens. However, just as with the first bottle of Hanssens I had, I would have to taste several other batches to say Girardin didn't belong in the same league as the other three. * Petrus is a very good Oud Bruin. Good Old Bruins (Flanders Browns) are hard to find. There are a lot of overly-sweet beers, with no sourness, calling themselves Oud Bruins -- beware. * I asked at Rodenbach if they consider their beer a "Red Beer" or an "Oud Bruin." They said it is a "Oud Bruin." Given that, I'd say shoot for something between Rodenbach Grand Cru, Liefmans Goudenband (the old recipe) and Petrus when trying to brew an Flanders Brown Ale. * Rochefort 10 is excellent -- IMO one of the three best Trappist beers (along with Orval and Westvleteren Abt). Rochefort 8 is also very good, has a similar flavour as the 10 and is far more quaffable. * You can get beers like Rochefort 10, Orval and Cantillon at grocery stores. 750ml of Cantillon Gueuze is BF 100 (about $3.25), a bottle of Orval will set you back BF 43 (about $1.40). * On the, "this is not lambik" front: you can buy Belle Vue Kriek in cans. * I tasted the Celis White in Brugge. I feel that it is not as good as the Celis White brewed in Austin. It didn't have as much of the yeast character. It is not surprising that it would be made from a different recipe there (as if Pierre was going to release his trade secrets). Incidentally, Hoegaarden Wit, along with Stella Artois and Jupilier are the most widely available beers in Belgium (Belle Vue Kriek is up there also). * At 't Brugs Beertje, Jan and I compared 9-year-old and a current bottle of Verboden Vrucht: no comparison. The night before, I ordered my wife Karen a bottle of the current stuff, expecting something like the Pierre Celis version. She hated it and I even had trouble finishing it. Obviously, Interbrew has ruined another great beer. The old beer was an explosion of fruit. The current smells and tastes more like a strong industrial American lager than anything else -- a Belgian Mickey's Malt Liquor if you will. * Jan ('t Brugs Beertje) rents out the Boon brewery one day per year and makes a 4,000 or 5,000 liter batch of beer. He then ages it four years before serving. Every year it is a different recipe and the kegs last only a few weeks when he puts in on sale. I tasted the beer served this year (he puts a small percentage in bottles) and it was a pale, citrusy, wheat beer made with sloeberries. Very fruity, but did not taste like a typical fruit beer. * Fresh Duvel is not as good as old Duvel. We're actually lucky to get it "pre-aged." Some cafes pre-age Duvel. Fresh, it smells solventy and the alcohol burns the throat. Even one year of aging turns it to silk. * The last two beers I drank in Belgium (I had planned to bring them home, but our luggage already weighed 390 pounds and that was after I airfreighted home 44 pounds of glassware) were scottish ales! Gordons Scotch Ale was outstanding: a peaty nose, much lighter than McEwans and much less sweet. It was deceptively strong, however. Highland Fine Whiskey Malt Beer (brewed by Henninger Brewery in Germany and packaged in a can!) was good: slightly smoky nose, more smoky in the palate, rather lager-like (duh!) perhaps a cross between a rauchbier and a scottish ale. Probably the best beer I've tasted from a can. * 173 beers critically tasted (if you don't count the Old Dominion Ale during our layover in Dulles), visited nearly a dozen small- to medium-sized breweries, performed countless hours of people-watching in numerous biergartens and cafes, ranched more than 30 (possibly different) yeasts, and saw some cool old architecture (some as old as Roman times). There's still smoke rising from my Visa card... I'd call it a successful journey. Al. Return to table of contents
Date: Thu, 17 Aug 1995 05:00:00 GMT From: fletch at poohs.com (Dave Fletcher) Subject: Caramel flavors - summary In HBD#1800 I posted a message concerning a caramel flavor that seems to be a regular attribute of my beers, and asked the collective what might cause this. As luck would have it, there was a fairly wide submission of opinions, and so it is difficult for a "novice" like myself to venture much from my original state of ignorance concerning same. Here is a rundown of the responses I received. 29% Favored the idea that high gravity boils as the most likely cause. 21% Favored the idea that crystal malt is the likely culprit. 7% Considered a long boil as the most probably the reason for caramel flavors. 7% Miscellaneous reasons were stated for caramel flavors including oxidation of the wort, yeast, and extracts which contain significant caramels. 36% Had the same or similar problem and wanted information. Perhaps the tried and true experts could lend a hand here and enter into a discussion on this topic with a bit more detail. I know I would appreciated it, and my relatively small sample would indicate there are others who would as well.

I have inherited a refrigerator that seems to stay on all the time. After using it for the first time last week, I realized that the thermostat inside doesn't work at all and the unit behaves more like a freezer. My question is when people are talking about various hunter, honeywell, and other manufacturer's products, do you need to replace the internal thermostat or do these work by turning the unit on and off. I'm not opposed to opening up the back and trying to replace the internal thermostat, but one that requires no real work would be better assuming that my refrigerator now just has two states, on and off.

If you stick an immersion chiller in the cold part of the kettle, ie the bottom, you get stratification. You will chill the cold part colder, while the hot part sits happily on top, staying hot. As for stirring, break, settling, and all the other problems associated with chillers, I would once again like to mention the planispiral chiller. Mine is 25' of 1/4" od copper tubing formed into a flat spiral, like an electric stove element. It is designed so that it lies about 1/4-1/2" below the surface of the hot wort. No need to stir, since cooling the top layer generates convection. I whirlpool the wort after the boil, let it settle for 10 min. or so, put in the chiller, let it sanitize for a few minutes, put on the lid and turn on the water. 20 minutes later, cold wort, no stirring, break settled, nice tight cone of spent hops in the centre of the kettle. I will confess that it is not perfect. Eamonn managed to get a temperature inversion somehow so he had a cold layer on top and a hot layer on bottom. Never happened to me, though. ed ---------------- ehitchcock at sparc.uccb.ns.ca the Pick & Fossil Picobrewery Because there's more to life than just coffee Return to table of contents

I didnt chastise anyone! I stated that I felt pitching at higher temps was bad, but also clearly indicated that this is relative to many other factors, yeast strain and the brewers desires being standouts. I will point out that most ales will generate between 5-10 degrees F of additional temp during high krausen, so if you pitch at 80F and dont attemperate I wouldnt want to drink many of the resultant chemicals. If you can rapidly drop and maintain a temp after pitching at 80F, the impact will be greatly reduced. This is near impossible for most of us. Certainly, the desire of all brewers is to produce beer *they* like, its a personal choice and one that makes brewing so individualistic. There is a large body of "Relax dont worry" homebrewers out there. There is also a large body of folks who would like to understand more completely the chemistry that is involved in producing this carbon soup that we all love so much. If you dont want to believe the experience of some "OTHER experienced" homebrewers like myself and A.J., fine. Go read some chemistry and brewing texts. There is bulk of detailed information on the subject of yeast metabolism, esters and fusel alcohol creation. Good brewing, Jim Busch busch at mews.gsfc.nasa.gov If some part of that music is heard in deepest dream, or on some breeze of Summer a snatch of golden theme, we'll know you live inside us with love that never parts our good old Jack O'Diamonds become the King of Hearts.

Date: Fri, 18 Aug 95 08:45:32 PDT From: rone at mdhost.cse.TEK.COM Subject: Hunter Air Stat Summary As several folks have pointed out here and in email, the problem with the Hunter units is a zener diode (Z1) on the board that switches the AC. This is a 24V, 5W device. The diode is obviously being pushed passed its published specs of 5W. The pc board (in my unit and probably all units) is scortched, even the solder connections appeared to have gotten hot enough to emit a little solder flux. A short term fix would replace the zener with a higher power part. The zener would have to raised off the board to prevent further scorching. So far, the highest power part I've found is 4W. I'm still looking. Thanks to everyone who replied with the excellent information. Ron Ezetta Return to table of contents
Date: Sat, 19 Aug 95 00:55:45 +1000 From: CHARLIE SCANDRETT <merino at ozemail.com.au> Subject: Amazing Amazonion Floating Brewery This is some interesting historical trivia. The Amazon river is a giant sewer for millions of people. When travelling the upper reaches in the dry season it is the only source of water. A couple of years ago I found myself in the Colombian branch of the northern Amazon sailing to Mitu on the Brazilian border. The boat was a brigt blue, 35 ft cocaine-lab supply canoe, loaded with gasoline, H2SO4 and ammonia. The hot brown water was jumping with pathogens lusting for my gringo intestines. However the local indians have long brewed their water to control nasties. These blokes kept two 5 gal tanks fermenting all the time. They would fill it up with water straight from the river, add "arepas", a sort of corn cake, lots of pinapple peels and "panella". Panella is raw sugar cane extract, crystalised in a solid block. It is sliced from the block into the fermenter with a wickedly sharp machete and a macho disregard for the lurchings of the speeding canoe or your fingers. The secret is the pineapple peels. Apparently a wild yeast cultures itself in the sweet ozings in the folds of the peel. A pineapple is a transportable yeast culture! (cafeful with fruit adjuncts folks!) The fermentation continues for 2 days and consumption is begun after a 10 minute lagering period. The brew is often topped up but is not drunk for a couple of hours after top up. The pitching and fermentation temps are in the high seventies as it is cooled by a wet bag, the SG would be about 5+, there never is a FG. The "room" temp is always +90F. This corn, sugar & pinapple beer tastes supprisingly good, prevents dysentry and keeps you mildly drunk. After 8 days of this "garaupo" and several hundred miles of trees, howling monkeys, crocodiles, mosquitoes and more bloody trees, I was pleasently numb. The shock of watching guerillas take a man away in a canoe to be shot lifted the ambience rapidly! My rapid exit from the region erased all thoughts of brewing until I found the photos the other day of Allidio's Floating Blue Brewery, complete with heavily armed smiling patrons!

Date: Fri, 18 Aug 1995 09:21:00 -0700 From: bgros at mindseye.berkeley.edu (Bryan L. Gros) Subject: british pale malt, homegrown hops Two questions: 1. I just bought a sack of Hugh Baird British Pale Ale malt. Are there any styles (besides lagers I guess) where a regular ( American I guess) 2-row malt would be better to use? Why is lager malt better for lagers? 2. Do fresh picked homegrown hops need to be dried to use? If you pick the cones and use them for finishing hops or dry hops without drying them, do you get the same results? I assume you need to dry them to store them. Thanks. Also, Jim Busch posted a quote describing the adverse effects of pitching and fermenting at high temperatures. If I'm not mistaken, the original concerns were just with pitching at high tempertures and letting the fermenter cool to normal fermenting temps. For example, if you have trouble cooling to 65F with your wort chiller because the water temperature is only 65F, so you chill for half hour till the wort gets to about 80F, rack, pitch, and put the carboy in a 65F cellar. Does the higher temp of the wort at pitching lead to faster reproduction of the yeast and lower lag times, and does the drawbacks of higher fermentation tempertures apply when the temperature is only elevated for 12 hrs or so. I guess that was three questions. :-) - Bryan bgros at mindseye.berkeley.edu Return to table of contents
Date: Fri, 18 Aug 1995 12:16:03 -0400 From: Chris Cooper <ccooper at a2607cc.msr.hp.com> Subject: New Micro in Michigan, Big Buck Brewery In HBD #1810 Bob Paolino asked about Michigan and Ontarion breweries. I live in Michigan and just returned from a week of camping in Michigan's beautiful UP (upper peninsula). On our way home we stopped in Gaylord, Michigan (app. 1 hour south of the Mackinac bridge and 4 hours north of Detroit on I-75) and visited the newly built Big Buck brewery. The micro opened over the 95 Memorial day weekend and has been going strong ever since. The brewery is apparently a well funded venture and features an excellent restaurant (steaks, chops, burgers from a large indoor flamed grill) and a large "bar" area arranged around the glassed-in brewery area (the bar has a beautifully carved railing and peanuts on every table end up on the floor creating a very relaxed mood). The building is cavernous and rustic but very modern in it's features. The beer (they had 7 varieties on tap when I was there) ranged from good to excellent , the darker the beer the better!! IMHO. While waiting to be seated (7:30 on a Wednesday night the wait was 45 min.) I asked the hostess some questions about the operation and mentioned I was a home brewer, Bingo that was the magic ticket, she brought the night manager over and introduced us. Paul (the night manager) spent about 20 minutes giving me and my family a complete VIP tour of the facility and showed us every nook and crany of the place, he said they liked to go out of their way for home brewers and made our experience one my whole family will remember. The brewery has regular tours Wed-Sat at 2,4,6 pm and is setting up a visitor's center and reception/tasting area in their basement. So for any of you out there in HBD land if you find yourself on I-75 headed for the north-country stop in Gaylord and check out Big Buck!
