Date: Thu, 4 Nov 1999 03:20:05 -0500 From: "Dan Kiplinger" <knurdami at iname.com> Subject: Aquarium heaters for lagering Does anyone know if a submersible aquarium heater will work to warm lagers to the appropriate temperature during fermentation? I have mulled over this thought for years and never followed up on it or tried it. I decided tonight that I was finally going to give it a go unless I was talked out of it. My plan is to get a submersible heater with the wattage recommended for 2 times the volume that I intend on fermenting (I will be fermenting 20 gal). If I remember correctly from my days as an aquarium sales dude in highschool, it was 25 to 50 watts per 5 gallons. This would mean that I would be looking to get a heater with a wattage between 200 and 400. 400 watts seems a bit extreme and I don' t know if that size of a heater would be in my $ range. With some sort of insulation on my stainless fermenter, this seems to be such a simple solution that I start to get worried. It seems to me that the amount of electricity that I will use will be no more than if I went through the trouble and bucks to build and insulated box to fit over my fermenter and heat the inside of that with a heating pad or such. The things that immediately worry me are: off flavors due to the beer directly exposed to the element, not having enough circulation to have the heat disperse well enough thus having different temps throughout the fermenter, and the possibility of other flavor concerns due to the plastic used in these heater housings. Well, I guess that I will wait to hear from the collective. PS. >>This is how wars between small countries start!<< I didn't mean to start a war. In fact, I don't want to see one. I just was appalled, that's all. I usually roll over and let things slide but this time I wanted to say something. Dan Kiplinger Return to table of contents
Date: Thu, 4 Nov 1999 07:30:33 -0400 From: "Darrell Leavitt"<Darrell_Leavitt at sln.suny.edu> Subject: Question: Munich Lager I pitched a large Wyeast smack pack, last week, onto a munich lager...and it took VERY long (6 days) to get going...and it is going very slowly. I know that I should have stepped it up prior to pitching, but was impulsive,,,and didn't plan ahead well. I am now going to slowly drop the temp to the high end of its temp range, but I wonder: does it make sense at this point to pitch more and hope to see it bubbling more, or might this risk infection..and am I best to leave well enough alone and just let it ferment out slowly? ..Darrell <Terminally INtermediate Home-brewer> Return to table of contents

Date: Thu, 4 Nov 1999 07:37:02 -0800 From: Demonick <demonick at zgi.com> Subject: iodophor question Bob, don't worry about it. Everything is okay. Your beer will be fine. From: "Sieben, Richard" <SIER1 at Aerial1.com> >Bob Fesmire related a no rinse use of iodophor yesterday and wanted to >know if he ruined a batch of beer. Well, that depends. It >sounded like you transferred into the just sanitized carboy before >letting it dry, that would be bad, especially if you made a lighter >bodied beer. Iodophore becomes inactivated when it dries, so you >should always have your equipment sanitized and dried before you use >it. All you need do is turn your carboy upside down a couple days >before you need to use it to let all the liquid drain out and have >time to dry, bad stuff won't crawl up into it, bacteria rains down >into things. Ok, so did you ruin your beer? Taste will tell, you >may get away with it this time. I have only ruined one batch of beer and >it was because one of my brew buddies had used iodophor at double the >recommended rate AND the beer was a very light bodied beer that can >show every defect. The beer was visually perfect, clear, good >head....but the taste was IODINE! YUCK!!! Iodophor is a no-rinse, no-dry, use-wet sanitizer. I'm not saying that you can get away with a pint of iodophor in your brew, but the flavor threshold is so high that the amount of iodophor, whether double-strength or not, clinging to the inside of the carboy or hoses after letting drip a minute or two, will not be perceptible. Though it was not mentioned, the Band-aid, perhaps iodinish aroma that some brews exhibit are NOT due to iodophor, but due to the use of chlorinated water or bleach. Chlorinated water can produce chlorophenols in your beer. These are medicinal smelling/tasting compounds that are often detectable at parts per BILLION concentrations. One of the most useful aspects of iodophor is the use-wet feature. During brewing sessions I keep a 5 gallon bucket of iodphor around to toss equipment and gear into so it's sanitized when I need it. Shake it off and use it, then throw it back into the solution. I fill my CFC and tubing with it. I siphon it out and start collecting when the iodophor has run out. I know that I'm getting some mixing and that some iodophor is making it into the carboy. Never had a Band-aid batch, but then I use very slowly charcoal filtered water.

Date: Thu, 4 Nov 1999 08:56:21 -0700 From: Ian Smith <isrs at cmed.com> Subject: Carboy blow-off!! Maybe I'm greedy but I usually put 6 gallons of wort and yeast into a 6.7 gallon carboy. Last night the fermentation was so violent that I lost at least a gallon in foamy blow-off! Has anybody out there solved this problem (apart from using a bigger carboy or less wort to begin with)? Should I boil the blow-off to sanitize it and return it to the carboy or am I asking for an infection? Maybe I could pressure cook the stuff or am I being too much of a tight wad and just throw it out? Cheers! Ian Smith isrs at cmed.com <mailto:isrs at cmed.com> Return to table of contents

Date: Thu, 4 Nov 1999 09:31:15 -0600 From: "Jack Schmidling" <arf at mc.net> Subject: Wine making vs beer As a personal note, I was making wine long before I made beer. I quit making wine because I could not produce anything better than what was then $5 jug wine. Not bad but no reason to make it. I then started making champaign because the Then $5 champaign gluted the market and I gave it up. I quit making beer because it was generally lousy. I attribute my renaisance to the internet but probably owe more indirectly, to that guy with the beard that everyone loves to hate. I have started making wine again but primarily because I now have access to my own grapes and other home grown fruits, which is the segue to what I feel, is probably the fundamental difference between making beer and making wine. Ponder this: home brewers have easy access to raw materials as good or better than that used by commercial brewers. Furthermore, 30 gallons or more can be made from a sack of grain that will keep for several years in a closet. Unless one lives in a quality grape growing region or has his own vines, one can at best buy "fresh" grapes trucked in from out of state and pay through the nose for them. More likely, the winemaker is stuck with what ever concentrate his local wine shop can get and this is even more expensive, difficult to store and of even more questionable quality. No doubt the concentrates are better then those of yesteryear but it is still not much different from making extract beer and look what happened to that market. It is unlikely that this sort of wine can ever be much better than jug wine and will always be more expensive to make. No offence to retailers but these are facts of life and I do not think even the man with the beard could have surmounted them if he had chosen to promote wine making instead of beer. I am delighted to hear that retailers are finding a surge in wine making supplies. I just hope someone comes along to do something clever to make it permanent other than just relying on the population growth to provide a continuous supply of novices who quickly lose interest. It is my humble opinion that retailers (and crafters) looking for an untapped growth area consider cheesemaking. It seems about where homebrewing was when I gave that up. It's ripe and ready for a man with a beard whereas as winemaking is looking for Viagra. You are invited to join the Cheese Makers Digest and get involved.

Date: Thu, 4 Nov 1999 13:02:05 -0500 From: Dave Burley <Dave_Burley at compuserve.com> Subject: Limits to Growth, quality winemaking Brewsters: I don't believe Alan Meeker and I disagree on the basic theory of yeast and what limits their growth. However, there are <practical> limits to growth as noted quite often in brewing texts. Such limits are imposed by just those sorts of things Alan talks about. My answer to Kyle stands: Expealadocious. Errr, The idea behind being able to limit the number of growth cycles depends on the practical observation that in normal, "typical" fermentations, the yeast population levels off. It does this in response to the various limiting factors commented on by Alan. So to answer Kyle's question again: By controlling the pitching rate, one can control the number of expansions the population has to go through to reach this typical maximum population. Doing this is important to get a consistent flavor, since many of the co-geners are produced during the growth phase of the yeast. These co-geners being more desirable in ales than lagers suggests a lower pitching rate for ales, as is practiced by the brewing industry. - ------------------------------------------------ On the subject of quality of home winemaking. Mine is better than most wines you can buy in my opinion and that of fellow wine drinkers and judges.. I do start with grapes from California, but like homebrewing, I do not have an accountant staring up my you-know-what. I am able to make excellent quality wine at home with about the same complexity of equipment as homebrewing. Frankly, I find it difficult to drink most commercial wine that I can afford. Grape wine based on California grapes, new bottles, best corks money can buy, capsules and labels still only costs me less than $5 per bottle. If you recycle your bottles or jug the wine, it is about $2-3 a bottle. This is for excellent stuff. A disadvantage is that we have to search out restaurants that will let you bring your own wine or pay a corkage fee, as my wife will drink no other by choice. I offer this as proof: The three bottles of red wine ( Petit Sirah, Pinot Noir and Cabernet Sauvignon) I entered in an American Wine Society competiton in a ( once only) weak moment ( at the request of my SO and friends) won two <national> gold medals ( PS & PN) and one bronze ( CS). Medals are only awarded if deemed worthy and only one is given per year for a given style. Judges were trained amateurs and professional winemakers who have to go through a rigorous three year training program and pass a final exam that is incredibly difficult. They do know wines. Point is not to brag, but to convince you winemakers and wannabees that it can and is done all the time at home with an excellent result. Interested in making country and fruit wines? Then get a copy of a hoary book, reprinted recently, called something like "Practical Winemaking" by Duncan and Acton. Should be available at your HB store or it can be ordered. I cut my winemakling teeth on this when it was first printed and it is still the best book for this purpose. For those grape wine enthusiasts, a book called "Home Winemaking -Step by Step" by Jon Iverson, Stonemark Publishing was just published. It is such a good book, I could have written it. [8^) and wish I had. Unlike many other hobby books, Jon and I agree on nearly every topic.

Date: Thu, 4 Nov 1999 10:21:19 -0800 From: Jim Cave <cave at psc.org> Subject: Zymurgy Bashing Dan Kiplinger indicates that Zymurgy has done wonderful things for homebrewing. I totally agree. However, those of us who have been in the hobby for a 10 or so years, will note two things: 1) Not only Zymurgy is not the magazine that BT was, it isn't the magazine that Zymurgy once was. I thought the special magazine was very thin on overall content. That's not a slight on the contributors, but rather the editorial staff. Perhaps the resources aren't there to pull it off. 2) It is rehashing the same material. Perhaps it is the nature of the hobby, but how many articles can be written at the beginners level on mashing? After a while they read the same. In technical or scientific journals, normally you don't get published unless you have a new contribution to the field. My main reason for not renewing my membership was the deterioration of Zymurgy. Just my 2 cents worth. Return to table of contents

Doug Brown" <jbrown at labyrinth.net> Subject: RIMS design thanks and question Hello All, I posted a question (almost a duplicate) about the affects of starting with cold water in a RIMS system, heating it up, and following with a step mash schedual. I have received many responses, but none mention their thoughts on how the beer would turn out. Has this ever been done before. I have placed my design in electronic form so you can see (hopefully) what I am thinking. Please see http://www.labs.net/jbrown/Doug/Brew/index.htm and choose the "Improved RIMS Design" link. I have descriptions under each drawing mentioning my comments about the given stage. I am really looking for all types of responses here including but not limited to: the good, the bad, the ugly (poor joke). Please send any responses to jbrown at labyrinth.net. I really don't wish to build this system if it will produce bad beer. Thanks again Doug Brown PS Thanks Rod Prather, Norman L. Brewer, Ian Smith, and Bob White. For those who suggested heat controller advice, I believe I added part of every suggestion to my C++ style pic code, see "C++ code to operate the RIMS pic controller". - -- -------------------------------------------------------- / J.

OK those who posted about beginners and Zymurgy are correct in that there has to be a magazine for intro to the hobby. But after one has brewed for 5-6 years where does one go? Is there an organization that represents and provides info for the homebrewer who has most all the technical textbooks and has attended Siebels and is considering the IOB exam? the AOB has little left to offer except their web site. And they can't get ti updated in a timely fashion. I am sure this is due to various time and financial limitations. Look a the beating Handspring is taking for being so inept at e-commerce. I'll continue to sing the praise of pat and karl (or is it karl and pat) and the volunteer effort they put together. they provide a great archive of useful info for FREE. MAD! magazine has compiled all their issues on CD. Find a picture of the devil and then one of charlie. I think it is a case of seperated at birth. And to the guys in michigan.

I don't have any plans for mine, but its not so top secret that you'd have to buy the kit if there were any. IGOR can be found at http://home.sprynet.com/~zymie/rims.html . You will want to take a look at Rick Calley's system at http://www.pressenter.com/~rcalley/index.htm . Also don't forget to check out Nate Wahls (OOGIE, OOGIE!) system at http://www.cros.net/cruiser/Brewery/nate_herms.html . I've seen other Heat exchange systems on the web, but never kept a list of links. Building one is not that complicated. BTW, when exactly was the term HERMS coined? I first used the term HEARMS in HBD 2617 back in January '98. Hmmm....kinda makes me wonder. Anyway, good luck with your system Jeff, whether its a $20 coil, or a $120 coil with helical doodads spun from unobtainium. Wayne Holder AKA Zymie Long Beach CA Return to table of contents
Date: Thu, 4 Nov 1999 23:58:22 -0500 From: "Conan Barnes" <barneco at earthlink.net> Subject: gelatin finings quick question for the brew medics, i have about half a case of a pale ale that i brewed a number of months ago. i haven't had any of it in a while, and when i went to pour one the other night, in most of the bottles i noticed a group of small particles floating just under the shoulder of the bottle, very close to the glass. my first thought was that i'm seeing my first infection, but i thought i'd make sure that it wasn't just yeast in suspension before i tossed it out. i believe this was my first batch using a secondary fermenter with gelatin for finings. i've heard that if gelatin is used improperly, you can end up with a gooey mess. while my beer isn't anywhere close to being jello, i'm wondering if it's causing my yeast to hang in suspension instead of settle. of course, maybe it's just an infection :P. no extreme off flavors that my uneducated palette can discern. what do you guys think? on an unrelated note... for our first anniversary my wife went all out and bought me a corny draft system(i'm still in shock about this one). what's the general concensus on keeping the co2 cylinder in the fridge vs. running a gas line from the tank outside to the keg inside?
