---------------------------------------------------------------------- Date: Fri, 28 Feb 1997 11:58:00 +1200 From: "Murray Mulholland (oldmail)" <MurrayM at WAIRC.GOVT.NZ> Subject: Lined Copper Brewpot Greetings from New Zealand. Following are some (probably dumb) questions from a reltive newcomer to the hobby of home brewing from the Southern Hemisphere. Any answers you can give me would be much appreciated. I have recently come by an old boiler and would like to establish its suitability for use as a brewpot. I would appreciate any advice from more experienced brewers out there. The boiler dates from the 1950's and was apparently designed for use in the catering industry. Before using it for brewing however I would like to be sure that it will not contaminate the wort during boiling. The vessel is copper but the inside is plated with another metal which has the appearance of weathered zinc or aluminium (i.e. dull light grey). Does anybody have any idea what this metal might be, or how I could test it to determine what it is. I understand that aluminium is generally considered safe for boiling wort, but what about zinc and other metals which it may possibly be? If it is not safe, then I might consider electroplating the inside with copper as an option? What are the practicalities of doing this at home? The vessel has two identical elements which contact the liquid, and it has two power settings:- medium (one element only); and high (both elements in paralllel). The overall rating for the boiler is 230V, 9.5A indicating that each element is probably around 1000W. Is this likely to cause scorching/burning of the wort?. Finally, on the subject of cleaning this brewpot, I note reference to a cleaning product called TSP or Tri Sodium Phosphate in the digest and in other brewing sources on the web.This is referred to as being available in paint and hardware stores for the purpose of cleaning surfaces prior to painting. I have never seen any product labelled TSP in New Zealand, but there is product commonly called Sugar Soap which is often used for this purpose. The packaging does not state what the main ingredient and is none of the retailers I have spoken to know what it is either. Is it possible that this may be TSP by another name.

The Sam Adams product typically tastes like a fairly bland american ale with cranberry flavoring added. If it doesn't, take it back. (Even if it does, I'd have taken it back, but that's just my taste. ;-) ) > Thanks, i know this isn't brew-related, but it is still beer related. > But on a brew-related comment, what exactly is a Lambic, anyway? Lambic is a spontaneously-femented ale brewed in a certain region of Belgium. It is fairly dry and sour. Those who like it consider it the _real_ "Champagne of Beers". Those who don't just consider it beer gone sour. Oh, and it's expensive ($2-6 per _bottle_) Due to it's sourness it takes fruit very well. So, if you like fruit flavored beverages, you will find Kriek (cherry) Lambic, Framboise (rasperry) Lambic, Peche (peach) Lambic and others. If the FTC had any rules about beer style advertising, Sam Adams' would never get away with that name. But then, a lot of micros would be in trouble too. - -- Paul A.

Date: Thu, 27 Feb 1997 17:54:01 -0600 From: Paul Niebergall <pnieb at burnsmcd.com> Subject: Bierre De Garde Home Brew Ingesters, FWIW, I have been trying to brew a decent biere de garde (ala Tres Monts, Grand Coulette, ect.) for a couple years now and have had some success. I think I have the grain bill worked out, it goes something like this (6-gallon batch): 10 pounds Belgian pale ale malt 1 pound Belgian Munich malt 1 pound Belgian malted wheat 0.5 pound Belgian CaraPils malt 4 to 6 ounces Belgian ?Special B? malt 1.5 pounds light spray dried malt extract (DME) 1.5 pounds Belgian candi sugar All malts (except the DME) are Dewolf-Coysins. This grain bill will give you a big beer gravity and flavor. For bierre de garde you want to get the gravity above 1.060 (in Belgium, I believe this classifies as a ?strong ale?). The above recipe yields about 1.067 (at 72 percent calculated efficiency) which I have found to be just right for bierre de garde, Belgian Triple, or strong ale. I add the DME because this grain bill exceeds my mashing capacity. The candi sugar adds a lightness and contributes to a subdued vinous flavor (that winey taste) which enhances a good strong ale. The ?Special B? malt is a really smooth tasting dark malt. I use it some for taste, but mainly use it for color adjustment. I steep it in a quart of water and add it little by little until I get the color I am looking for (this is really useful when trying to brew a Belgian Double (dark) versus a Belgian Triple (light). I believe that Tres Monts you specified is more of a blonde color, so you may want to leave the Special B out all together. Now the hard part, the yeast. I have made beers with the above recipe (or slight variations thereof) on three occasions. Twice I use Wyeast Belgian Ale (1214). Both times it came out way to estery. The first time fermentation temperature was about 75 degrees F. That beer came out tasting like Bazooka Bubblegum. It was really gross at first, but with time (months) it actually tasted pretty good. The second time the fermentation temperature was about 60 degrees F. This time the beer came out really good, but it still had a banana flavor that wasn?t quite to style. The last time I made this beer (just bottled it last Saturday) I used Wyeast Belgian Strong Ale Yeast (1388). I was so paranoid about esters, I fermented it in the garage at about 58 degrees F (way cold for this yeast, but I got good activity and attenuation anyway). I tasted the beer when I bottled it and guess what, no perceptible esters. The only problem is the beer tasted a little too clean and smooth, no winey, estery, or phenol character that you really need in a biere de garde or strong ale. But anyway, that?s how it tasted at bottling time. Time will be the judge on this one. Anyway, I can't seem to get the yeast right. I would rather use a commercial version if one is available. Does anyone have any ideas out there. Nazdrowie, Paul Niebergall (pnieb at burnsmcd.com) Return to table of contents
Date: Fri, 28 Feb 1997 11:30:27 +1030 From: Stephen Neate <Stephen.Neate at adl.soils.csiro.au> Subject: re:Coopers Sparkling Dave Sapsis presented a very well written synopsis of the Coopers Brewery operations in Adelaide. I only have two small nit-picks. The Malting facility is in an outer suburb of Adelaide and is closer to 10 Km north of the city centre, the Brewery being about 5 km east. I guess the two may be about 15 km apart. The dry yeast supplier in case anybody is trying to source them is Mauri not Mowry. They are a very large firm servicing the food industry. As far as I know all malting barley grown in South Austalia and Victoria is grown by private farmers using cultivars bred by the Universities and Agriculture Departments and in the public domain. Together South Ausrtalia and Victoria produce about 50% of Australia's malting barley. Coopers new malting facility is indeed large and impressive, but there are other maltsters in Australia, the most widely spread and probably the biggest is Joe White Maltings which is in most barley growing states.

Date: Thu, 27 Feb 1997 21:19:56 +0700 From: "C.D. Pritchard" <cdp at mail.chattanooga.net> Subject: Re: building a RIMS heating chamber Dion posted that one >needs to take it apart after EVERY brew and clean it... Left to dry it will eventually turn to the black carbonized crud. And if it does >not dry between brews, it can even rot on you. Dion's post prompted me to pull the heating element from RIMS. First time in 5 mashes. The only deposit on the element was a dusting of carbonate which brushed off easy. There was was about .5 cc of nonadhererant, odorless brown material at the very bottom of the element housing (i.e. on top of the element's base). I suspect this is residue from malt particles that made it through the pump. Otherwise, the element looks like a new one. The keys to not crudding-up RIMS heating elements are: 1. Have a decent flow (>1/2 GPM or so) during mashes. Running it even breifly without flow is a definite no-no. If one is prone to doing this, consider interlocking the heater with the pump electrically. 2. Don't overheat the wort in the chamber (I kill heater power when the wort discharge temp is >2 degF over the target rest temp.) 3. Run at least a batch of hot water through the system as a flush before storage- I flush twice, once with tap water then recirc with a gallon or so of 168 degF water for ~5 minutes. 4. Put a drain valve at the bottom of the chamber to both drain wort and flush water and as a air opening so the inside of the chamber can dry between uses (the other end is has open tubing so a bit of air can circulate). The valve connects to the chamber about 1/4" above the element's base. If I was doing it again, I'd put it flush with the heater base. This would help eliminate the brown stuff I noticed. c.d. pritchard cdp at chattanooga.net http://caladan.chattanooga.net/~cdp/index.html Return to table of contents
Date: Thu, 27 Feb 1997 17:10:47 -0800 From: Sharon/Dan Ritter <ritter at camasnet.com> Subject: re: splitting CO2 to multiple kegs Scott Rohlf writes: >I would like to know the best way for splitting the CO2 from >my regulator to service both kegs. I actually would like 3 outputs. >(2 kegs and CPBF). Bolted inside the back of my beer fridge I have a 3-line valved manifold. The incoming line (running from the CO2 tank thru the wall of the fridge) branches to three ports each with a shut-off valve. Attached to each port I have three kegs in various stages of conditioning/lagering. On one of the ports I have attached a small regulator that steps down the pressure below what is coming in on the main line. That way I can have a lager conditioning at 17psi and an ale conditioning at 7psi. All my hardware came from Cliff Tanner at Braukunst (1-800-972-2728). The initial investment is kind of high but the convenience and versatility is worth it IMO. A 3-line distribution manifold costs around $40 and the small regulator was custom built for me by Cliff and ran about $35. The only drawback is the mass of hoses and valves inside a refrigerator that sometimes has four kegs crammed in it! Numbering each port and gas line helps.

Date: Thu, 27 Feb 1997 22:08:18 -0600 From: Terry Neudorf <tm.neudorf at sk.sympatico.ca> Subject: Priming Sugar This is my first posting. I see many things here that interest me about homebrewing. I've been brewing for about 2 years using extracts, I haven't yet graduated to mashing but I plan to. With that in mind after reading "The Joy of Home Brewing" by Charlie Papazian I followed everything except how big a brew pot do you use. Do I have to boil the whole 5 gallons? If so that's a pretty big pot! Anyway my subject concerns priming sugar, I live at an altitude of about 2200 ft. and I have used as much as 1 2/3 cup corn sugar for priming with no blowups although I have to cool my beer as it is quite gasy warm. I'm talking 5 Canadian gallons here. What's the deal with Charlie Papazian, I thought his brewing book was the best I've ever read! Good Brewing Return to table of contents

Date: Thu, 27 Feb 1997 22:02:19 -0800 From: Kelly Jones <kejones at ptdcs2.intel.com> Subject: Re: AHA yow yow In HBD #2361, Scott Bridges hits the nail on the head with an eloquent description of the AHA: In summary, it's not an association of members, it's a business, owned by Charlie Papazian, whose sole purpose is to make money for Charlie and his 'Angels' and support their globe-trotting pub crawls. What's more, this is all perfectly legal. If you don't like them lining their pockets with your money, or don't think the magazine alone is worth the dues, don't give them your money. The only problem with this model is that homebrewers really NEED and WANT a national organization to act in THEIR best interest. I belong to a local club that does this on a local level, but with with the (hundreds?) of thousands of homebrewers in this country (and our neighbors), it would be nice to have a national organization which served our needs.

Date: Thu, 27 Feb 1997 13:03:58 -0600 From: Rick Olivo <ahspress at win.bright.net> Subject: RE: AOB/AHA AN OPEN LETTER TO CHARLIE Dear Charlie: You probably don't know this but you've always been something of a hero to me. You are one of a select few that has been responsible for bringing the grand avocation of homebrewing to untold thousands of people. You helped make the magical art of brewing your own beer accessable to the masses. Buy a new brew kit, whose book is it that comes with the plastic fermenter, carboy and ubiquitous "kit" of malt extract? Charlie P's. For your contributions, you deserve a stained glass window in the homebrew hall of fame. Thus it saddens me a great deal to read all that has transpired in the various threads concerning the AOB/AHA. I am especially saddened to see your answer to the various, quite serious charges that have been made against those organizations and you personally. At a time when a comprehensive answering of the charges was needed, we got a soliloquy about the good old days. When we should have been looking at hard facts we got hard cheese about how you had nothing to apologize for. While I understand your point of view, and to an extent sympathize with it, (No one likes to deal with a pack of baying hounds) I must say, it's not enough, Charlie, not by a long shot. I have seen that kind of answer before. I have seen it from the Watergate to Whitewater. It has the stink of cover-up all over it. Understand, Charlie that I am accusing you of nothing. I have no basis in fact to make any accusations. I write to warn you that you are headed down a perilous path. It is a path that leads to class action suits, to Internal Revenue Investigations, to newspaper investigative reporters snooping through every tax record, interviewing every disgruntled former AHA member, sticking tape recorders under your nose every time you step onto the street. It isn't a thing that is going to go away. It gets worse, like an open sore that stinks worse with the gangrene of scandal every day you allow it to fester. Charlie, you may say I envy you, and you would be right. Who wouldn't? You are living the kind of life, at the head of an orgainzation you founded that is the envy of every homebrewer. You are a very lucky man. You are also a very intellegent man. You would not have risen to your present position if you were not. You must be smart enough to know that the current level of anger caused by your stonewalling is only bound to rise. You must also realize that, as the head of a non-profit organization, you owe your loyalty to the people who foot the bills. You have a responsibility to be forthcoming to them. I tell you this as an impartial outsider. I am not now, nor have I ever been a member of AHA or AOB. I tell you this because of my admiration of your achievements, in full recognition, that as a man, you are fully as capable as any of the rest of us of pulling a boneheaded mistake. I only hope that you will show us your quality and make the kind of reforms that would make AHA the kind of organization I would be proud to join. I pray that you do it soon, before the organization you have worked so very hard to create is dissolved in the acid of this increasingly bitter and divisive struggle. I say this to you as a contemporary and homebrewer of 25 years standing. I was homebrewing years before it became legal in the United States. I know how far our avocation has come in the past 25 years. I appreciate what you have done for homebrewing. I hate to see what is now happening. It's sad and it's stupid. You alone have the ability to bring this mess to an end, and to allow homebrewing, AHA and AOB to continue to prosper and develop. Show us that you are indeed a man of vision and not the arrogant power-hungry moneygrubber some have made you out to be. We ask no more and expect no less.

Date: Fri, 28 Feb 1997 00:37:40 -0800 From: "Layne" <wetpetz at oberon.ark.com> Subject: New Brewer lookin for advice on next step Hey all, I've been looking at HBD for some time as they occasionally get posted in some of the newsgroups. Today I decided to sign up. I've been making wines for two years and I decided that it was time to do beer. I love good beer and I've been buying various 650 ml bottles of Microbrew for a few months to figure out what I like and what I would make. The HB shops in my town are fairly limited as far as experience and materials available so I've been getting all of my information from the net. I have ordered Charlie Papizans Book at the book store and it should be here in a week. I tried an extract ale first. (Monton's) and It was okay but the corn sugar made it taste watery and kind of like a Molson brew. Not bad but not what I've been getting from microbrew beers. Next I tried a double extract Pale Ale and I used Crystal grain, Hop pellets and I actually boiled it. I devised the recipe by looking at the Cat's Meow at the Brewery and used similar techniques although I couldn't get the ingredients to copy a recipe exactly. It's brewing now but I've had problems. I would really like folks to see what I've done so I can get some feedback on my process and solutions to problems. I've put a page up describing what I did at http://oberon.ark.com/~wetpetz/pale.html If nothing else I think you more experienced brewers will have a chuckle or you might be sick at the way I brew. I do need some questions answered though and they are in the page. I intend to get into All Grain Brews but I am contempt to use extract until I find a good source for ingredients, ie mail-order or a trip to Victoria/Vancouver someday. I bought a 20 L SS pot the other day for $20 new at a variety store. I hope to get a 10 gal Gott and another pot for mashing but I'm not sure yet. It will be a while, I want to read that book first. I'm looking forward to learning and drinking good beers. I'm sure that this will be a good source for that even though it may involve weeding out the flames about AHA. Layne Rossi P.S.

I've found descriptions of the system components on various web pages, and I think I have an idea of what they're getting at, but I'd like some sort of informed explanation of the whole thing.

Date: Fri, 28 Feb 1997 08:34:13 -0800 From: George_De_Piro at berlex.com (George De Piro) Subject: RE: Counterflow chillers & trub removal/mashing vs steeping Hi all, Dave Burley explains that he finds it easier to remove trub with his counterflow chiller than with an immersion chiller. He does this by using a chore boy pad as a filter on his racking cane at the ENTRANCE to the chiller. While this would help remove hot break, it will not remove COLD break, which is what I was talking about. Cold break is made up of proteins and lipids, etc. that are soluble at high temperatures, but crash out of solution upon rapid chilling. They cannot be filtered out of hot wort with a porous filter. Jim Cave's method of allowing the cold break material to settle does work well (I used to do this), but I never seem to have enough free carboys around to do this anymore. I also don't like the idea of the cool wort sitting around unpitched for a few hours, although I never did have a problem with this method. ----------------- Patrick asks what the difference is between mashing and steeping. Mashing involves actually converting starch to sugar through enzymatic action, while steeping just dissolves the sugars in malts that are "pre-converted." In practical terms, there is a higher grain:water ratio when mashing, and all malts can be used, because saccharification of the starches occurs. Only malts that have been saccharified in the husk (like crystal malt) can be steeped. If you try to steep non-saccharified malts, you'll end up with starch in your finished beer. This is useful only when making pLambic. Have fun! George De Piro (Nyack, NY) Return to table of contents
Date: Wed, 28 Feb 1996 11:46:26 -0500 From: "Larry F. Byard" <lbyard at gwi.net> Subject: True Brew Ale? A couple of weeks ago I decided to venture into using liquid yeast. The only liquid yeasts available at our local health food store were "True Brew Ale" and "True Brew Lager." Being anxious to advance after reading everything I could find on yeast, I bought the ale. The package also says 'a product of Wyeast.' Does anyone know which Wyeast Ale it is? If appearance, as compared to previous batches made with the same recipe, using Edme dry yeast, is any indicator, the ale I made last Saturday from this yeast--which started a little slower than Edme, but is still bubbling every 10-12 seconds after six days--is going to be quite good.

A question for the judges: When rye constitutes a significant proportion of the grain in a beer, how does one compete with it? If brewed as an IPA, for example, should I enter it in the IPA competition, or should I enter it into some "other" category, with the dryhopped huckleberry wheat lambic stouts, for example?

This method of filtering at the >entrance end of the racking cane is effective whether you are dealing with hot >or cold wort and can therefore be used with the CF chiller or the immersion >chiller. my experience with agitating trub is exactly as dave describes it. however, unlike dave, i have never been able to draw the wort out of the kettle gently enough to prevent some of the trub from re-dispersing. even the slight motion (induced by the fluid flow) near the end of the racking cane is enough to send my trub back into solution. i also end up wasting a lot of wort this way, as i can never tip the kettle up without the trub sliding down toward the racking cane. and in the settling tank later, when i rack off the trub, there is always a little bit of trub still in suspension. it's not much at all, really, but it's never "brilliant" wort. patrick stirling asked: > what's the difference between >mashing and steeping? I thought mashing *was* steeping, i.e. soaking the >crushed grains in water at a specific temp. for a specific time. this is kind of like the "pale malt" and "leaf hop" debates we've had before. in order for us to communicate properly........ mashing is familiarly used to mean manipulating a grist/liquid "mash" to induce enzymatic action. temperature, pH, mash thickness, etc. are regulated to create the desired wort characteristics, which carry through to the final product. for an example of where mashing is not simply "soaking the crushed grains in water at a specific temp. for a specific time", consider how pilsner urquell and many other beers are produced: decoction mashing. some portion of the grist bill must contribute enzymes. steeping does normally not imply any sort of enzymatic action. you're just trying to dissolve soluble items from the grains. in this definition, no enzymes are required for the process to succeed. these are just semantics, really. the above descriptions fit most of what i've read about brewing. it is important to understand how these terms are typically used. brew hard, mark bayer Return to table of contents
Date: Fri, 28 Feb 97 11:42:00 EST From: "Bridges, Scott" <bridgess at mmsmtp.ColumbiaSC.NCR.COM> Subject: Trub removal question The recent trub removal thread has me wondering. I've never removed the trub from my wort. I use a CF chiller and end up with all the cold break in the primary. I just read about someone (sorry, John Varady maybe?) who allows the trub to settle in a holding tank then transfers into the primary and pitches the yeast. Would there be anything wrong with pitching the yeast in the holding tank? Would the yeast settle out with the trub? Gut feel says no. I'm assuming that the yeast would already be in suspension. Any other opinions? Would this give a shorter lag time all other things being equal? I use Irish moss in the kettle and seem to get a really masssive break that takes time to settle. I'd be concerned about leaving the wort to settle a long time (like overnight) without pitching the yeast. Scott Return to table of contents
Date: Fri, 28 Feb 97 11:16 PST From: cburns at egusd.k12.ca.us (Charles Burns) Subject: CF vs Immersion and Pellets vs Whole It appears to me that the disagreements between the users of CF Chillers and Immersion chillers regarding Cold Break and other gunk really revolve around the use of whole vs. pelletized hops. I use mostly pellets with immersion chilling. I whirlpool the wort at end of boil, cover it and let it sit for 15-30 minutes while I clean up and play with the dog. I have a piece of nylon gauze covering the bottom of my racking cane to filter the gunk (trub and hop). I rack from the side of the kettle into a 6.5 gallon glass carboy. I always end up with a large pile of hop spooge and trub from the cool break in the center at the bottom of the kettle (8.25 US gallons). I leave about 2 quarts of wort in there with the gunk. I can see where having a counterflow chiller would cause me to end up with a _lot_ of crud in the carboy, mostly hop spooge. With whole hops in the kettle only, I can easily see that a counterflow chiller would work just fine leaving all the hop spooge behind and all the hot break and the cool break. I call it cool break because I usually chill the wort down to 80F degrees for pitching, and then the wort with the yeast cools down to between 60F and 64F, and then I get the cold break (maybe a quarter inch layer at most) overnight. So, if I decided to convert to a CF chiller, I would also make the move to whole hops at the same time. I've been thinking more about going with whole hops anyway because I just swear I've made better tasting beer that way when I have used them. PS - the two quarts of gunky wort I leave in the kettle stay there overnight (covered and cool) and the next day I strain that wort into quart sized jars and store the wort in the refrigerator. When it comes time to make a starter, I already have the wort (no need to purchase DME). I _always_ re-boil the starter wort for 10 minutes (wouldn't want to die from botulism) after thinning it down to between 1.030 and 1.040 before cooling and pitching any yeast (which I recover and wash from earlier fermentations). This process is very cost effective, making the cost of a batch only that of the grains, hops and propane. Charley Return to table of contents
Date: Fri, 28 Feb 97 19:28:16 GMT From: blades at airtime.co.uk (Liz Blades) Subject: Yeast and Ph of water Hi, Here in the UK it is the norm to use dried beer yeast. Most of the instructions say to rehydrate the the yeast in water(I know,Iknow). A problem that has arisen locally is that the Ph of our water supply has reached a staggering 9.3. This has the effect of killing the yeast. Do you know if any studies have been done to quantify the tolerence of yeast to Ph values of common or garden tap water? One of our manufacturers is going to carry out experiments in this field,and I will publish the results as soon as I can. Can I stress that we are interested in rehydration of yeast in untreated tap water and not any other medium such as wort or treated water. TIA Private email welcome.

Yet beers > in brown bottles as well as green do get photochemically skunked > and/or at least get labelled as skunked. I'll try to give a not-so-wild-ass guess for points 1 and 3. Light is energy, and compounds can absorb energy from many sources. Others have pointed out here that heat can skunk beer just as light can. A beer may be packaged to keep the light out, but still skunk because it was stored outdoors on a warehouse loading dock in the summer. Try microwaving a beer. This can also explain your point 3, i.e. it's not really a photochemical reaction that causes skunking, rather a change in chemical state caused by any source of excitation. I tend to doubt this explanation because it's too simple, and I'm sure the folks at Miller, Bud, etc. would have come out with it by now. Of course, judging by their products they might just *like* skunked beer. As for point 2, someone posted a few digests back a theory about surface area, mercapatans (spelling?), and olfactory senses that seemed reasonable and would explain the behavior. Since no-one has come forward to poke holes in it, why not consider it more strongly? If you really want to answer some of these issues, you will have to resort to performing physical experiments at some point;) SM Return to table of contents
Date: Fri, 28 Feb 1997 17:17:01 -0600 From: Palmer <johnj at primenet.com> Subject: Iodine vs. Stainless - Metallurgy Howdy Group, I am finally getting set back up with HBD access after my job change. Al Stevens wondered: Are there any metalurgists out there that could tell me why chlorine is not bad for the SS that is used in the dairy industry, but bad for cornelius kegs? The answer is: Probably because the chlorine based sanitizers and cleaners that the dairy industry uses are Inhibited (usually with silicates) to help prevent corrosion. There is a big difference between using a chlorine based inhibited sanitizer and using Bleach on stainless steel. All of the Halogens attack stainless steel, but Iodine is less corrosive to stainless than chlorine at the conditions that homebrewers are concerned with. Dairyman too for that matter. But in terms of commercial use, chlorine based solutions are more common and less expensive, thus their higher percentage of use. Doesnt mean that they are better. Bleach, being what most homebrewers have access to, is very corrosive and that is why we tend to cite Iodophor as a preferred sanitizer. Also, Iodine is not much for Cleaning, so dairymen, looking for an economical combination cleaning and sanitizing agent would go for chlorine-based.

Date: Fri, 28 Feb 1997 13:17:45 -0800 From: RANDY ERICKSON <RANDYE at mid.org> Subject: AHA / Fermenting in 10 Gallon Cornys / Dave Draper? Thanks to everyone who sent me mail and posted about the AOB/AHA thread. I left the HBD when it started coming several times a day last fall and just returned to see quite a spirited thread. On the one hand it is good to see an expanded Board of advisors that included many respected brewers including a few from right here on HBD. On the other hand, I have some direct experience with an advisory committee related to a research project conducted by a California government agency. Unfortunately, all the experience in the world and the best of advice means little when the staff has full authority to do as they please. And that sure seems to be the case at the AHA currently. I'm hopeful that if enough of us get fed up and leave, they'll have to become more responsive in order to survive. My only consolation is that they need my support more than I need theirs. ********************** George Schamel asks about Fermenting in 10 Gal Cornys and posted a summary of lots of good advice. I occasionally ferment large batches in a thirteen gallon keg. The keg is stainless, but is rubber coated at both ends so I can't use is as a boiler. However, the snap ring pried out easily, the dip tube lifts right out, and all I needed was a Number 11 stopper to complete my fermenter. It's heavy when full (double batch) though, I can barely lift it to a bench by myself for syphoning. I'm not really comfortable lugging around much more than a 6.7 gal full carboy, at least for any kind of distance. As I recall, George, you said that you had a bad back, and I'm curious how you intend to move around large quantities of wort and beer. Do you have some sort of pump that won't degrade the fermented beer? ********************** Finally, has anyone heard from Dave (I'm not from here, I just live here) Draper? His website in Australia seems to be gone, and see he hasn't posted in well over a year. Thanks all -- Randy in Modesto Return to table of contents
Date: Fri, 28 Feb 1997 13:20:20 -0800 From: Charles Burns <cburns at egusd.k12.ca.us> Subject: re: Steeping vs Mashing Steeping will extract existing sugars from highly kilned malts like Crystal or Caramel. It will also extract color and flavors from malts like chocolate and black. Any starches in grains that are steeped will be extracted as starch, unless the steeping is done with a water/grain ration of <= 1.5 quarts/lb AND you include some pale malts that still have enzymes intact (and of course, that's what mashing is and that's the difference).
