---------------------------------------------------------------------- Date: Tue, 24 Jan 1995 11:53:56 EST From: Bob Paolino Research Analyst <uswlsrap at ibmmail.com> Subject: RE: Coffee brew Jonas Hartzler in Carbondale asks about using coffee in beer: I wouldn't put the beans in at all, ground or whole. I'd be concerned about the oils. To lessen that concern, I simply make a big pot of strong coffee (variety/roast chosen according to the style of beer and the coffee character I want) and add it toward the end of the boil. The coffee character will be very strong when the beer is young, so give it some time in the bottle. (And for you Madison readers, I don't want to hear any jokes about that coffee cranberry stout I did a couple years ago!) While we're on the topic, here's a suggestion that I heard a while ago--put hops in your coffee. It sure made sense to me--after all, my freezer door is occupied by bags of coffee on one side and hops on the other. Put a couple of flowers (or crush a few pellets) in the filter basket with your coffee. Cascades work wonderfully with darker roasts. Experiment a little to find the taste you like. Although I hadn't actually done that combination (hops in coffee rather than coffee in beer) before, I had thought of it before it was brought to my attention. Someone at work was leaving to pursue other interests in Seattle. I made my own going away card: the front read, "Hmmmm.... it smells a little like Seattle in here." On the inside, I attached a small plastic bag containing some hops and coffee beans. Now go have a beer, Bob Paolino / Disoriented in Badgerspace /uswlsrap at ibmmail.com Return to table of contents
Date: Tue, 24 Jan 1995 12:33:43 -0500 (EST) From: "Dana S. Cummings" <dcumming at moose.uvm.edu> Subject: fruit beers A brief word of caution regarding the addition of fruit to the secondary. I made a straw/rasp berry ale in which I added 5-6 # of fruit to the secondary after fermentation had slowed considerably. The introduction of all that sugar caused a large increase CO2 production. The reason why: my fruit floated and plugged my blow off. My advice is to leave plenty of headspace or have a large diameter blowoff.

Date: Tue, 24 Jan 1995 09:40:14 -0800 From: gtinseth at teleport.com (Glenn Tinseth) Subject: "Rare" UK hops Gary Bell asks about Challenger and Progress hops from the UK. Here's what I have (snarfed from the Just Hops catalog) Challenger: AA% 6.5-8.5, BA% 4.0-4.5 A granddaughter of Northern Brewer bred in England. A true dual purpose hop with a spicy aroma and fruity flavor. It blends well with other hops. Progress: AA% 5.0-7.5, BA% 2.0-2.5 This is a good aroma hop bred from a Whitbread Goldings variety. It has a flavor similar to Fuggles but slightly sweeter. Disclaimer: I haven't brewed with either. Glenn Return to table of contents
Date: Tue, 24 Jan 95 12:55:54 EST From: Steve Robinson <Steve.Robinson at analog.com> Subject: Steam Safety Kirk Fleming writes: > I advise folks to be mightly careful with any steam generating > apparatus they might build and use. If a solenoid (for example) > fails, be certain other failsafe mechanisms shut down production > and relieve steam pressure (if any). Things like modified pressure > cookers can be deadly--no joke. This needs a little clarification. Steam generators made from modified pressure cookers can indeed be deadly, if their inherent safety mechanisms are disabled. ----------------------------------- - ------------ The generator that I use is made from a modified pressure cooker. Typically, it takes about 0.5 psi to push steam through the mash. If for any reason the steam line were to clog, the weight on the stem of the pressure cooker would start relieving pressure at 15 psi. If this mechanism were also to fail, the plastic bung in the pressure cooker lid would blow out before the pressure limits of the cooker were reached. If these safety mechanisms had been disabled, then the pressure in the cooker could build up until its limit was exceeded and it would explode violently. One other word of warning with steam. Make sure that your injection line has no leaks in it. The same large heat capacity that make steam such a great energy transfer medium also mean that if it comes in contact with flesh, it can burn really badly. Since I ususally have a two year old running around underfoot while I'm brewing, I get really anal in checking this. That said, with a little common sense safety applied, steam generation can be a wonderful addition to a home brewery. Steam is a much more efficient mechanism than hot water infusions for raising the temperature of a mash, particularly for reaching the higher target temperatures (eg mashout). I heartily reccomend it, particularly for those like me who mash in picnic coolers and would just kill for a method to apply direct heating.

Date: Tue, 24 Jan 95 12:07:57 CST From: docherty at Arco.COM (Shane Docherty) Subject: pH vs Temp ?? Does anyone have, or know where to find, a table of pH vs temperature changes? I use a Checker pH meter and generally mash in at about 126F for lagers. I take a small sample and cool to 60F. then take about 0.35 off the pH reading to adjust for the temp. difference (this is the the only adjustment number I've found - Papazian I believe). I'm having another go around at playing with and refining my water treatment and pH control so any data would be useful. Also, does anyone know of a reasonably cheap way or place to get your water tested for ion concentrations? I'm too cheap to fork out the $50 per ion they want up here, so just had the local water store do their free tests on samples of boiled/decanted and plain water from my well and guessed the rest from there. (I buy distilled water from them to mix with my well water for pilsners) FYI I use reagent grade phosphoric acid for my pH adjustments - works really well. Thanks in advance ....

Date: Tue, 24 Jan 1995 13:31:37 EST From: Robert Bloodworth ZFBTO - MT0054 <debaydr9 at ibmmail.com> Subject: koelsches Wasser To Michael Valentiner, You asked about water used to brew Koelsch: >I am looking for the essential ion concentrations of the brewing water in >parts-per-million (ppm or milligrams/Liter): > Calcium (Ca) > Magnesium (Mg) > Sodium (Na) > Bicarbonate > Sulfate (SO4) > Chloride (Cl) >Also what is pH of the water? Do they do any kind of water treatment? If >so, what do they do and what is the ion concentrations of the water that >is added to the grist? The braumeister at the Brauerei Paeffgen in Koeln (Cologne) gave me a bit of info that may help you. Paeffgen is not typical of the breweries in Koeln. It would probably be considered a microbrewery in the States, as they only sell draft beer in their own pub (and a couple of select others) and some party-kegs. The braumeister told me that although they have their own water well out in the hills east of town, problems with runoff from the intensive agriculture practised in the area forced them to stop using it. Upon analysis, they found that the city water was softer than the stuff they got out of the well, anyway and very clean! (Not surprising, based on the tough new water purity standards enacted here in the late 80's.) On the basis of his experience, he feels that the importance of using very soft (10?dH) water for brewing his kind of beer may be overrated. In any event, his volumes are so small that the added expense of an ion-exchange set-up doesn't make economic sense and they have been using the water pretty much as is for a couple of years now without any noticable drop in beer quality. He also says that although he personally likes some of the other Koelsches at least as well as his own, Paeffgen's is the consensus best in the city. Virtually everyone I have talked to agrees with this assessment, although Reissdorf Koelsch would come in a close second! I have it on good authority that the makers of Gilden Koelsch (a good bottled brand) draw their water from their own well. Gilden does, however, use a weak-acid ion-exchange resin to reduce the hardness of their water (as they generously explain during the brewery tour). Here is a water analysis for the region of Koeln containing the Paeffgen brewery. 7.13 pH 103.7 Calcium (Ca) 15.4 Magnesium (Mg) 51.9 Sodium (Na) 86.1 Sulfate (SO4) 109.0 Chloride (Cl) Total Hardness: 18?dH (?dH = German degree of hardness) 3.22 mmol/l Hardness due to Carbonates: app. 8.5?dH (?dH = German degree of hardness) * Source: Rechtsrheinische Gas- und Wasserversorgung Aktiengesellschaft 1991 as reported in Trinkwasser in Koeln "Wie jot es et denn nu wirklich?" from KATALYSE e.V. Institut fuer angewandte Umweltforschung. Sorry about the units on the hardness, but I'm not a water chemist and am not sure how to translate " ?dH ". I'll try to find out what this means in terms of the bicarbonate concentration in the next couple of days and let you know. Let me know if you have other Koelsch questions. The braumeister at Paeffgen was very helpful and I'm sure I'll drop in and visit him sometime soon. BTW Koelsch is actually spelled Kolsch, but I'm not sure you'll receive the umlaut (let me know if you do)! A few bits of trivia about the water in Koeln (Cologne): Interestingly enough there is a famous Carnival (Koeln's Mardi Gras) drinking song that has as its refrain: "Dat Wasser von Kolle es jot!" Which is the local dialect for : The water from Koeln is good! Also the word cologne stems from the famous "koelsches Wasser" or literally water of Koeln also known as "4711", one of the worlds oldest commercial perfumes, which originated in Koeln. It appears that Koeln's water may indeed have magical properties. now go and have a beer, Bob Bloodworth Koeln Return to table of contents
Date: Tue, 24 Jan 1995 11:28:41 -0700 From: "Roger Grow" <grow at sumatra.mcae.stortek.com> Subject: Coffee, LONGMONT Brew Club - The Tribe! The coffee first, Jonas Hartzler asks about Coffee in Beer (HBD #1639); My advice about coffee is - the later the better. I have tried adding coffee all throughout the brewing process and have concluded that adding brewed coffee (I use espresso) with your priming sugar gives the best coffee flavor in the beer. How much? I use eight 'shots' of espresso in my Express-O-Stout recipe amd it only adds a nice aftertaste. You can experiment by adding small amounts of your favorite coffee directly to the bottle before you cap. Beware, my experience is with dark coffees (full city or better), so I dont pretend to know about light roasts. Also, coffee is like crystal malt, it gives off nasty flavors at temps above 190F (73.5C) so dont boil it. ATTENTION LONGMONT LURKERS!!! I know youre out there (John), so come join The Tribe, Longmonts first homebrew club! The first meeting is Thursday, Jan 26 (yup, tomorrow) at 7:00. So come one, come all, come naked!

Is that really the way it is? Absolutely not. I'm sure you can find a judge here or there that is partial to Cascades, but the AHA Club-Only competitions are judged by various clubs in various cities, so any biases would be local and not nationwide. What I mean by local biases is that in some areas certain stylistic opions are common -- e.g. a tendancy towards higher bitterness, a tendancy towards US hops, a tendancy towards fruitier ales, etc. It does not have to be associated with a region either. A particularly skilled, respected brewer in a club may start hopping very highly and dryhopping everything with Willamettes. Subsequently, the less experienced brewers in this group may tend to do the same. This might be a club in Portland or it may be club in Orlando. Also, Gary writes: >Finally, there has been quite a bit of discussion about head- >retention lately. I've been getting fabulous, thick, white heads >on my ales consistently when I've use British DME that I buy in >bulk. I had assumed this was due to dextrins in this extract, >which tends to finish at higher gravity than American extracts. Is >there any reason to expect that this British DME is higher in >head-building proteins than American products? I would say yes. The largest manufacturer of malt extract in the US uses 6-row barley. Since 6-row has a much higher protein percentage than 2-row (which is used virtually exclusively in the UK), I am quite sure that an extended protein rest is used by the manufacturer. If the protein rest is done at the low end of the proteolytic range (i.e. around 122F) then the resulting beer will be thinner in body and have poorer head retention than if an extract was used which was made with a fully-modified 2-row barley and a single-step infusion mash. Another point, this time regarding the liquid extract from this same American manufacturer -- I've found it to be rather variable at times. Sometimes it produces good head retention other times poor head retention. I've always had very good and consistent head retention when I used Munton & Fison extracts. **** Dave writes: >I am building a bar in a second floor loft of my home.

I am planning on running the lines inside an insulated tubing. >Will I still have problems keeping it cold? 15 feet of vertical can be a tough one especially for low-carbonation beers. The key to your problem is large inside diameter hose. See Dave Miller's article in the 1992 AHA National Conference Proceedings or there is an article on kegging in an upcoming issue of Zymurgy by our own Ed Westemeier. Insulated tubing may be enough if you use the system often, but if not and you have a lot of disposable income, you may look into a glycol cooled hose. You could build it yourself if you are handy. Basically, it involves threading all your beer lines into a larger, insulated tube *along with* a "pair" of tubes for glycol. Some faucet towers even have "in" and "out" connectors for glycol. Dennis Davison and Chris Campanelli have Beer Engines in which the pump cylinder is jacketed for glycol cooling (can you believe that!). In any event, you loop the glycol tubing back, up near the faucet and put a pump and a coil inside the fridge. The tube is filled with glycol and then the pump pumps cool glycol up along with the beer and then back down for rechilling. ********* Tim writes: >priming with 3 ounces of black treacle, which is molasses. They may be related, but the two are quite different in flavour. ***** George writes: >I'm assuming that if in a 10 gallon batch, my OG reads 1.052 (for example) and >I have used 17 lbs of grain to get there, that my extraction rate >(Homebrew method) is: > > 100 * 52/[#lbs * #gals.] = 52/[17lbs * 10gals.] = 30.6 > >{The 100 at the beginning, used to get extraction in percent} You have the theory right, but I think you typed the formula in wrong. It should be: pts/lb/gal = (points * gallons)/pounds_of_grain So with your example (which worked only because you used 10 gallons and added an extra 100 in the numerator) the math would be: pts/lb/gal = (52 * 10)/17 = 520/17 = 30.59 Another way to look at it is "point-gallons/pound" which is equivalent because the gallons is in the denominator of the denominator, i.e. pts/(lb/gal). Since, as someone pointed out a few days ago, there are two "efficiencies" it is much easier for all of us, when we are talking about our systems to simply say, "I got 27 points from the DeWolf-Cosyns Aromatic" and the understanding is 27 points/(lb/gal). This will be universally translatable among all all-grain homebrewers. ****** Kirk writes: >What is the distinction (for American amateurs) between >cask conditioning and priming in the keg? The terms seem >to be synonymous as I've seen them used. You are absolutely right -- they are synonymous. The beer naturally carbonates (conditions) in the keg. ****** Todd writes: >Will a drastic change in temperature from 100 to 55 degrees kill the yeast? >This was ale yeast which to my understanding ferments between 65 and 75 deg. It may kill some of them, stun some of them and make the rest sluggish. They should recover, but if you would have rehydrated for 30 minutes (the recommended maximum time, according to a newsletter I have from a yeast manufacturere) that 100F water probably would have cooled slowly down to about 80F or so. Also, I recommend pre-boiling that 4 gallons of tapwater the day before brewing 1) to sanitize it, 2) to drive off chlorine and 3) so that it cools to room temperature overnight. Now you are adding a gallon of 100F wort to four gallons of 65F water and the result will be much closer to the 80F yeast than what you did. Yes you can rehydrate some more yeast and pitch it into this batch, just in case. If you stunned too much of the yeast, you will have a slow ferment (which is more likely to bacterial and wild yeast problems), higher diacetyl in the resulting beer and a higer than normal final gravity.

Date: Tue, 24 Jan 1995 12:40:59 -0800 From: Steve Peters <stevep at pcx.ncd.com> Subject: legal kegs -> kettles For those of you out there who would like to turn a keg into a kettle without the fear of running afoul of the law and you happen to live in the NW: Last weekend I had the pleasure of taking the Olympia Brewing tour. In their gift shop they sell shiny Olympia kegs for $30. These are the kind with the bung in the side, but I have seen them converted into kettles before. The tour was suprisingly fun. The guide we had knew more about the process than most guides do at larger breweries, and Olympia Brewing has clearly taken pains with their facilities to make the tour enjoyable even for us microbrew fanatics. I also found out how you can have draft beer in a can: They don't pasturize the canned "draft" beer, the same way they don't pasturize the keg beer. Tricky. The beer tasting results: Olympia beer was amazing in its clear lack of any flavor whatsoever. The Olympia Dark (available only on draft and at the gift shop) had a noticable amount of tasty chocolate malt. In contrast with this experience we also stopped for the Rainier tour in Seattle. The tour started with a somewhat insipid video aimed at people who never quite got that GED. The facilities tour was OK, though very brisk. Worst of all the Rainier brews we tasted all had that skunky cheap beer taste that gives beer a bad name. Sigh. - -- ...+ Steve Peters : stevep at pcx.ncd.com ....|..

Date: Tue, 24 Jan 95 13:39:21 -0700 From: John Glaser <glaser at widlar.ece.arizona.edu> Subject: G. Fix mash schedule questions I've got a question for you all-grain gods and master brew-chemists. Several months ago, there was a post by George Fix regarding a 40-60-70 degree celsius (104-140-158F) mash schedule for highly modified malts. I switched to this schedule and have gotten good consistent results. I use 30 min at each time, BTW. I raise from 40 to 60C with a boiling infusion plus a little added heat, and use stove to heat from 60 to 70C. I get a typical O.G. 1.050 and F.G. of about 1.010 (from memory, I don't have my notebook here, and assuming my hydrometer is not too far off the mark). According to Dave Miller (Complete Handbook of Homebrewing, or whatever), for starch to be available for conversion to sugar, the starch must be gelatinized, which occurs for barley at 149F. So, what does the rest at 140F accomplish? Or, is Miller's info outdated, and if so, what is actually happening? I have noticed that the mash does taste sweet at the end of the 140F rest, although I haven't measured S.G. at this point.

The boiling is the result of steam formation (not creation of O2, H2 and H2O), so HSA should not be a problem. I would guess that the creation of steam tends to blanket the surface area of the wort in the kettle, so any slashing due to boiling does allow O2 to interact with the hot wort.

Date: Tue, 24 Jan 95 16:24:02 -0700 From: grow at sumatra.mcae.stortek.com (Roger Grow) Subject: Fat Tire Recipe at last! A long time ago, Michael Sabo aske me to pass on any Fat Tire recipe replys. Michael, Sorry I've taken so long to reply, no one responded with a recipe but I've had some personal sucess. I found one recipe after I attempted my own. Heres mine; Flat Tyre 6 lbs light extract 2 lbs amber extract 1/2 lb 20L crystal 1/2 lb dextrine malt (carapils) 1 oz Chinook hops 1 oz Cascade hops Wyeast 1056 American (aka Chico) Scant 3/4 cup of corn sugar for priming Add 1.5 gallons cold water and the grains (in a bag) to your boiling pot. Spend about 30 mins bringing the water to a boil. I use medium high on my generic electric range, high boils too quickly and doesnt give the grains enough soaking time. Remove the grain bag just before the water boils. Remove the pot from the heat (to prevent scorching) and add the extract. Replace on the heat and add 3/4 oz chinook hops - boil for 60 min. Add 1 oz cascades for the last 15 minutes of the boil. Cool to about 100F (chiller, ice bath, snow drift or divine intervention) Add cooled wort to 3 gallons cold water in your primary fermenter. When the temp is less than 80F (should be by now) add the yeast and shake the snot out of it, um, I mean, aereate the wort. When fermentation is complete, make a 'hop tea' by boiling the remaining 1/4 oz chinook hops (I know, not a classic aroma hop) with your priming sugar. Bottle, wait at least three weeks and enjoy. Primary ferment - 3-5 days (1056 starts slow) Secondary ferment - 7 days O.G. - 1.046 F.G. - 1.016 The beer turned out great! Not exactly like Fat Tire (thus the name) but close enough for me. It doesnt have that Fat Tire wheat taste, but I'm not a big wheat beer fan (shields up Mr. Data). The yeast is an important part of the flavor so buy, beg, culture or pilfer some if you possibly can. If you buy a packet, definately make a starter because 1056 seems to start slow. The second recipe comes from the Rocky Mountain Homebrew December '94 newsleter. (If you have a Mosaic or Netscape browser you can find their homepage at: Some neat stuff in there.) Here goes; RECIPE OF THE MONTH Fat Tire Clone (extract) 3.3 lb Light liquid malt extract 3 lb Laaglanders Ex-light Dry Malt 1 lb crystal malt (30L) 1 lb wheat malt 1 oz Northern Brewers Hops (boil) 7.5%A 1/2 oz Willamette hops (flavor) 1/2 oz Saaz hops (aroma) 2.3%A 3 tsp Irish Moss (15 minute boil) 2 tsp Gypsum #1214 Belgum Ale Liquid Yeast or culture from several bottles of Fat Tire Belgium Ale. O.G. 1.055 F.G. 1.014 Culture: Start yeast culture before you brew. Yeast should be at high krausing at pitching time. I have found that starting yeast cultures from bottles of Fat Tire is very hit and miss. I had to go through 3 bottles before I found one that had enough yeast to start a culture. You may want to use WYeast liquid yeast cultures and save yourself a lot of frustration. * Water: Boil and refrigerate 3 gallons of tap water or buy 3 gallons of bottled (not distilled) water and refrigerate. Brewing: Add Gypsum to 1 1/2 gallons cold water. add cracked grains and steep at 150 degrees F for 30 mins. Remove grains. Add liquid and dry malts and bring to a boil. After boiling starts add boiling hops. Last 15 minutes of boil add flavor hops and irish moss. Last 2 minutes of boil add aroma hops. Cover brew pot and place into a cold water bath for 30 minutes. Then add 2 1/2 gallons of refrigerated water to sanitized carboy. Add cooled wort to carboy, top off with more refrigerated water. Cork and shake to allow oxygen into the wort. Add yeast culture and attach blowoff tube. place in a dark place and allow to ferment. Bottling: Prime with 1 1/3 cups of Laaglanders Ex-light Dry Malt Allow 3 weeks of bottle conditioning at room temp when using dry malt to prime. Comments: Using Laaglanders Ex-light Dry Malt gets this brew very close to the original Belgium ale. This is because of the tendancy of Laaglanders to have a high amount of unfermented sugars in it and in turn producing a sweeter finish which is characteristic of this Belgium ale. The wheat malt is added along with the #1214 Belgium ale liquid yeast to give the brew that classic Fat Tire's (1) aftertaste. (1) Fat Tire Belgium ale is a produict of the New Belgium Brewery, Lakewood, Co. The above recipe was reproduced with permission from the cool folks at Rocky Mountain Homebrew. Please forgive any typos, theyre mine. I hope you find this useful or at least tasty! Roger Roger H Grow Cave Boy Pico Brewery Longmont, Co Return to table of contents
Date: Tue, 24 Jan 1995 15:25:15 -0800 (PST) From: Jeremy Ballard Bergsman <jeremybb at leland.Stanford.EDU> Subject: Lautering problem I am extremely hesitant to post the following question for fear of reigniting the false bottom/copper manifold/em flamefest, but I have a lautering problem with my new false-bottomed lauter tun. It is an upside-down, bottomless 1/2 BBL keg with a custom-made adaptor comming out of what was the tap/pump hole for a drain with a perforated SS false bottom. I made two batches with no problem, in fact I had very fast clearing, and high flow-through rates. The next two batches (the last two) have had the same problem: everything starts out well, but near the end (when the SG of the runoff is ~1.025-1.030) the runoff suddenly becomes VERY cloudy. It is not macroscopic particulate matter, and it doesn't seem to be starch as it is not affected by addition of amylase enzymes. Hints: I only have N=2 but the appearance of the cloudiness might be correlated with changes in the height of the hot liquor layer waiting to percolate down through the grain bed (I'm still working on the float valve). I don't think it is a temperature effect as both the hot liquor and the grain bed are at ~170F. The pH of the hot liquor is actually less than that of the mash, probably ~4.5-4.7. I have never heard of problems of overly acidic hot liquor so I don't correct my tap water which has this pH (it is not strongly buffered to this pH either). If anyone could shed some light on this I would appreciated it. TIA. Jeremy Bergsman jeremybb at leland.stanford.edu Return to table of contents
Date: Tue, 24 Jan 1995 17:23:02 -0500 (EST) From: Jim Herter <James.M.Herter.1 at nd.edu> Subject: Lager Bottling Conditioning I have a lager (5 gal.) which is approaching its four week anniversary in the secondary fermenter at 34 F. I used the Wyeast Czech Pilsner which I pitched from a 16 oz. 1.02 O.G. starter into a carboy which was 1.048 O.G. The specific gravity was taken before it went into the fridge at 1.013 and after three weeks in the fridge it's still at 1.013. With all that said, here are the questions; Many different sources say anywhere from 3 to 6 weeks minimum in the secondary. Is there that much of a discernible difference in quality from 3 to 6 weeks? It's been stated that I will need to add some active yeast to the conditioning bucket because of the potential inactivity of the yeast. How is this process best handled? I plan on doing another lager while the temp is still cool (within the next two weeks) in the old coal room. If I make a starter for this lager; Can I double the quanity of the starter for the chosen strain of lager yeast and use half for bottling? Does it have to be the same strain? If available I had planned on using a lager blend! Since the beer will be at 34 F, what effect would that have on the yeast that's at room temp in the bottling bucket? Do I let the secondary come to room temp for a day with the fermentation lock still intact then mix with a starter? Should I start my next lager and extract x amount of fermenting wort, then add to the bucket? How much would I extract? What effect would this have on the new batch? (I'd prefer not to take the fermentation lock off at high krausen in the environment that the carboy is kept for primary fermentation). I realize that this may seem like very basic questions, but I have not seen any info on this topic in the backlog of HBD files that I have. If appropriate post to this bulletin board, if not direct email will do. Thank You! James M.

Yes, if your objective is to build a RIMS system strictly according to the definition invented by Rodney Morris, you are missing something, and that is even heat distribution during the mash brought about by recirculation. While recirculating wort at the end of the mash surely clarifies it, this is only one of the purposes of the RIMS concept. It is my opinion that anyone can truly claim to have implemented the RIMS concept if the wort is continuously circulated during the entire length of the mash. The insertion of heat can be done in any number of novel ways, Rodney's and mine happen to be electricty (for 10 gal or smaller batches). dion - -- Dion Hollenbeck (619)675-4000x2814 Email: hollen at megatek.com Staff Software Engineer Megatek Corporation, San Diego, California Return to table of contents

Its URL is: http://alpha.rollanet.org/ ===> Gerry Nelson asks about hot side aeration: >HSA; Why isn't this a problem during vigorous boil? Because during the boil, there is no air dissolved in the boiling liquid.

Date: Wed, 25 Jan 95 07:55:44 EST From: cem at cadre.com (Chuck E. Mryglot) Subject: New revision of Suds I just took a look at the new version of SUDS (rev 3.1). I have used the previous version (3.0c) on occasion. The significant difference that I see in 3.1 is a new IBU algorithm. I suspect that the 3.1 IBU calculation is based on the much debated formula recently published in Mark Garetz's book. eg. At rev 3.0c, a recipe has a calculated IBU of 28. the same recipe in 3.1 will show an IBU of 18..... quite a difference. The beers I have brewed seemed to be hopped properly based on the 3.0c calculation. If I followed the 3.1 formula I suspect I would be way over hopped. I checked out BRF and it tends to agree with the 3.0c formula. Anyone know what the new and old formulas for IBU calculations are? Anyways, I'll stick with the old formulation. cheers, chuckm Return to table of contents
Date: Wed, 25 Jan 95 09:38 EST From: Tom Clifton <0002419419 at mcimail.com> Subject: Optimum feed rate for a roller mill The subject has come up regarding the "correct" feed rate (as in feet per minute) for a motorized mill. This would likely effect the quality of crush as well the condition of the grain due to possible shattering or heating of the grain if crushed too rapidly. Specifically this is in regard to a mill my father is making from the Chris Barnhart plans. The mill has been changed a bit by its use of 6" long X 3 5/8" diameter hard maple rollers. The drive is via an electric wheelchair motor that turns at 180rpm at 12 volts which seems awfully fast for such a diameter roller as this would result in a feed of around 180 feet per minute. Also of concern is the torque available from the motor. It is spec'd at 20 inch pounds when running on 24 volts with a draw of 8.4 amps. As the mill isn't complete yet I don't know if reducing the speed further to increase the torque is necessary because I havn't the faintest idea how hard the thing will be to crank. Any words of wisdom from the readers of the digest end would be appreciated. Thanks! Tom Clifton St. Louis, MO. - --------------------------------- End forwarded message Return to table of contents
