---------------------------------------------------------------------- Date: Fri, 17 May 1996 17:08:11 -0500 From: John Wilkinson <jwilkins at imtn.tpd.dsccc.com> Subject: RE: Hunter Airstat In hbd#2039, Scott Kaczorowski asked about controlling a refrigerator with a Hunter Airstat. Although I have no experience with that particular device, I have some general information on the subject. Scott asked about freezer temp. My experience has been that the freezer temp will depend on the temp at which the refrigerator is set and the temp of the surroundings of the refrigerator. If the refrigerator is kept at ale fermenting temps and it is not in a hot environment, the compressor will not run enough to keep the freezer very cold. There is only one refrigeration unit in any refrigerator I have seen with the bulk or all of the cooling done in the freezer with cold air ducted to the refrigerator section to cool it. One disadvantage of the Hunter type controller that the refrigerator plugs into is that when the unit is shut off there is no air circulation in the refrigerator. Normally there is a fan circulating air in the refrigerator to keep the temp even. This may depend on make and/or model, though. I used the type controller that replaces the normal thermostat in the box. This is a bit more trouble as it has to be wired in (no big feat) but the advantage of leaving any circulation fan in operation and being cheaper to boot. Mine cost ~ $22 at Grainger, although that may have been wholesale. I hope all this helps. John Wilkinson Return to table of contents
Date: Fri, 17 May 96 15:34:00 PDT From: "Gregory, Guy J." <GGRE461 at eroerm1.ecy.wa.gov> Subject: advertising and rye. Al Korzonas posts, in HBD 2039: >I suggest that the HBD software be modified so that non-subscribers >cannot post. This will not only reduce the number of ads such as this >one, but also eliminate all the "please subscribe me" posts. If a >subscriber gets out of hand and starts posting ads repeatedly, they >can be silenced by unsubscribing them. Well, sir, as much as I find myself agreeing with you on other topics, I must disagree here. I submit that doofus posts and intrusive goofy advertising is part of the price of freedom in this venue. How do you know you want to subscribe if you can't download and lurk for a while? If an exclusive club is what HBD wants, this place will quickly lose both quality and me. Judging from your previous posts, I think after reflection, you would concur. I can't stop furniture stores from advertising during hockey games, either. Ronald S. Thomson <cky163 at crocker.com> asks about rye: >I have found the recent thread on rye interesting as I have been considering >using rye in a wit beer. I'm looking at having the rye at 5% - 7% of the >grain bill with the rest being split between pilsener and wheat, Sounds good....I've never mixed wheat and rye. I don't know at 7% if you'll even taste it, so I'd use flakes. > should I use malted wheat with the rye instead to avoid >a stuck sparge? Stuck or slow sparges with wheat, rye, and oats, are all due to the fine grain size of the material clogging up the pore spaces between barley grains. I've got some data on this which I'll post as soon as I fix my modem at home and get it written up. You can see the finest of these grain sizes as the cloudyness of most wheat and rye beers, and in oatmeal ales (its not just for breakfast anymore). My old zapap got stuck because the valve could remove wort faster than the grain could pass it during sparging. Take your time, it should be OK. > will rye contribute to the haziness of my wit at this amount (I've had problems maintaining a >haze in my recipes)? Oh, yeah. But another poster indicates his rye beers clear. Perhaps he or she is more patient than I. >is the sourness rye sometimes contribute appropriate to the wit style? I don't know. In my experience, rye is'nt sour...it's dry, or astringent. I think rye and wheat would make an interesting flavor. Maybe I'll give it a try. Thanks all you ryeguys out there for the great emails.

Date: Sat, 18 May 1996 15:28:48 +1000 (EST) From: Ken Willing <kwilling at laurel.ocs.mq.edu.au> Subject: Priming w/wort or dextrose: Crabtree I recently asked if other people have found, as Dave Miller has (and I have) that bottle priming with malt-extract/wort produces noticeably higher esteriness (in brews fermented with ale yeasts) than if priming is done with dextrose. (Miller attributes this effect to the normal production of esters - -- by a renewed "normal" three-phase fermentation, inside the bottle -- but which cannot then be flushed out because the bottle is sealed.) Al Korzonas replied that he doubted that this extra accumulation of esters in fact occurs, and that I must be tasting something else. Fair enough. But Al also cast doubt on my basic reason for priming with malt extract, which is in order to use up some of the oxygen in the bottle, in order to retard staling. (Miller says, quite baldly [CHHB, p.169]: "Because of the Crabtree effect, glucose priming has no effect on the level of oxygen in home brewed beers." [Whereas wort/malt-extract priming *does* consume oxygen.]) But Al says: > ... There is nothing inherently different between the yeast's > oxygen uptake with various primings. They consume the oxygen because they > desire it and the type of sugar used for priming doesn't affect that. I wonder if anyone out there would care to venture an adjudication of this. If my wort priming (which I claim results in too much esteriness) is not doing me any more good, oxygen-wise, than dextrose priming, I'd obviously like to stop priming with wort.

Date: Sat, 18 May 1996 10:09:11 -0700 From: Todd Bruce <tbrucer at ix.netcom.com> Subject: Brewing Calculation Question As an all-grain novice, I need additional understanding on some common calculations when formulating beer recipes. PPG: I read in the All-Grain Zymurgy special issue that PPG is defined as: (SG - 1) * 1000 * gallons - ------------------------------ # of grain Is gallons measured directly after the sparge and before the boil or is it measured after the boil? SG: When a recipe publishes the Starting Gravity, is that for the 6.5 gallons of runnings or the 5 gallons of wort? Extract Efficiency: How do I calculate this? And again, when is it measured, pre-boil or post-boil? Thanks in advance for any sage advice! Return to table of contents
Date: Sat, 18 May 96 11:00 EDT From: cdp at chattanooga.net (C.D. Pritchard) Subject: Infection from dry hopping In HBD #2037, Bob Bessette reported an infected batch which he attributed to dry hopping. Several have posted that they've not had any detectable infections. I tried dry hopping twice- the last batch was infected. Out of 30+ brews, that's been my only infected batch (I'm kinda AR about sanitation) so, I attributed it to dry hopping and will never dry hop again. Consider where the hops may have been before you received them. Look at the photo of the guy laying in a mountian of hops in one of Charlie P's book. Some vegatable growers are using "treated" sewage sludge on their crops. Who's to say your hop grower doesn't and the picker hasn't spilled your hops in the dirt or the wind hasn't blown some of the sludge dust onto your hops? If, as has been written in justification of dry hopping, the acidity and hop level of the brew inhibits infecting organisms, why do most of us bother with sanitizing kegs, bottles and racking equipment? OK, rant mode off... If a taste and sniff of the brew tells me it needs more hop flavor and/or aroma, I add a hopped tea. I use boiled, pH 5.5 (treated with lactic acid) water to make the tea with and always boil the hops for at least a minute to minimize the probability of an infection. Sure, the 1 minute boil reduces the amount of aroma but one can just use a bit more hops. In addition to the increased sanitation, I like the control teas afford- you can add a measured amount of the tea to a measured sample of the brew and taste/smell the mixture to help determine how much tea is needed. Also, you can add flavor- something dry hopping can't do. C.D. Pritchard cdp at chattanooga.net Return to table of contents
Date: Sat, 18 May 1996 09:17:54 +0100 From: Kirk R Fleming <flemingk at usa.net> Subject: Gelatin Finings & Autolysis >From time to time I use gelatin in the conditioning tank before it goes to the cooler. This tank is a Corny keg into which I racked the beer from the secondary. After enjoying the contents of the keg and pouring out the remains prior to cleanup, I've noticed the sediment is often a thin, very compact sheet of yeast and semi-solid gelatin. Even with dip tubes that haven't been cut off (I don't cut them off anymore since I haven't found it does any good anyway), the beer comes out crystal clear even to the last pint. THere appears to be no pick-up of yeast even when drawing from very close to the surface of this gelatin-yeast layer. Q1: Is it possible that the action of the gelatin in precipitating the yeast also encapsulates the yeast flocs or in some other way acts on them to eliminate or reduce autolysis? Q2: How might the question be answered empirically? Q3: Does anyone give a flip? KRF Colorado Springs Return to table of contents
Date: Sat, 18 May 1996 13:14:04 -0400 From: gscott at io.org (Geoff Scott) Subject: Request for through-put info It's not hard to tell that some people are getting tired of the mill thread but at least it's related to brewing. I'm collecting through-put information on various mills. I'm asking the interested to send me via e-mail, the amount of base malt that is processed through your mill in a given number of revolutions. The fact that I'm interested in through-put doesn't mean I think it's one of the most important factors in comparing mills. It's more a place to start since it's fairly easy to measure. The amount of response I get will determine whether or not I'll commission further studies of milling parameters that are harder to measure. Please let me know about any variables you consider important. I'll be collecting the info on my web page. regards, Geoff Scott gscott at io.org Brewing page http://www.io.org/~gscott Return to table of contents
Date: Sat, 18 May 1996 13:21:20 -0400 (EDT) From: Eugene Sonn <eugene at dreamscape.com> Subject: mini-keg rupture Hey there HBD, Since so many people have been asking about 5l mini-kegs, I thought I would tell a brief story from today. I have been using mini-kegs for 1.5 years or so. I bought my tap and first keg from Williams brewing, but bought extra kegs and bungs from a local homebrew shop. The extras are white with gold trim. They have the word "beer" in several languages on them. Well, this morning I hear a strange hissing sound from the beer storage closet (I don't have a basement). Turns out the keg had ruptured a bit and was spitting out beer. This was a batch of holiday ale made in february. Bottles of the same batch are fine. As I see it, this shows that you have to be careful when priming in these kegs. I usually drink the beer more quickly than I have been in the past few months. When it's consumed within 2 months of brewing, I have had no problems with ruptured or exploding mini-kegs even though I prime the whole batch at 3/4 cup corn sugar per 5 gallons. Overall, I'm very pleased with this keg. Even though the beer pushed the keg beyond its limits, it only leaked. No grenades, no shrapnel, no big problems. I guess this means the "honeymoon" is over and I'll have to start priming the kegs at lower levels. Anyone have any good suggestions about how to prime different rates in the same batch?

An English (Imperial) pint is 19.6 US oz.; so you see, a pint's not a pound the world around. The new extra 2 oz. or so is for the head. The old ones (of which I have a dozen or so) had to be filled brim full. This isn't a problem in the south, where they don't like or expect foam, but in the north it is.

Every time *anyone* has an *anything* to say about Mills, EZMashers, Skewed Rollers, Fixed Rollers, etc. on comes Jack with a "rant" to defend his *product*.

Date: Sat, 18 May 1996 15:06:48 -0400 From: RMoline930 at aol.com Subject: Varied <HuskerRed at aol.com> Asks about lager temps for his deep freeze, British Pints. You have run into the problem that plagues breweries, like ours, that do not have Uni-Tanks capable of individual temp control. You can't set the coolroom temps (or deep freeze temps) to allow one batch to complete primary and another to be secondaried. This is the reason such breweries rarely stray far from ale production. PITA, for sure. Noonan warns about temps exceeding 60 F, and states "Ideally, the maximum temperature should not rise above 47 -52 F." What's the solution? Get another deep freeze or a fridge to do primaries and use the D-F for secondaries. 1 pint British = 1.2009 pint US 1 oz British Fluid = .96076 US Fluid 1 pint British = 20 oz British Fluid <rlabor at lsumc.edu> on Fridges The best trick is to take a case of your best brew and introduce yourself to the blokes who install appliances for major department stores. These fellows always bring back used equipment, when doing an installation, except on a new construction, and when Mrs. Gottrocks changes her kitchen decor from beige to white, you can be the beneficiary! A mate of mine, Dewey Adams of Savannah, Georgia does this for several major department stores and usually sells them for $ 20 or so to second hand appliance guys, who clean them up and resell for much higher. If things work out, be sure to bring another case of brew, personally labeled. YMMV. <rmccorkle at nmsu.edu> asks about sparge levels and Crystal malt in mash. Just prepare a larger volume of sparge h2o than you think you'll need and sparge at a rate that keeps the level about an inch above the bed. Then simply sparge (slowly; a slow sparge is a spiritual thing, good for the soul and great for the beer!) until you hit your target volume in the kettle. Be sure to do a recirculation until the runnings are clear before collecting in the kettle. Bingo! Just put your crystal in the mash. <dmercer at path.org> worries about wheat beer foam. I think you have just discovered the power of the mighty 'Head Grains.' Many brewers add a small proportion of wheat or flaked barley to their grain bill just to enhance head retention. Cooled bottles may also help reduce the practical problems though. Rob Moline Little Apple Brewing Company Manhattan, Kansas P.S. Switching over to new e-dress <brewer at tfsksu.net>.

Date: Sat, 18 May 1996 16:13:59 -0500 From: cerevis at mcs.net (Christopher Weirup) Subject: messy white stuff... Hello all, I suppose I shouldn't worry, but I just want to check to make sure. I have a pale ale in the secondary right now and I noticed white particles on the top. They look like spores or lilly pads, if that helps describe them. At first there were just tiny bubbles, and there are still bubbles around them. I have no idea what this could be, I am being to worry that the homebrew is contaminated. The beer used 6.6 lbs. of light liquid extract, 1 lb. DME, about 15 HBU ofhops, and was dry-hopped with a hop tea for five gallons. It was in the primary for seven days with no apparent problems. When I transferred it, it tasted fine, with a gravity of 1.020. I used the Wyeast London strain. I've kept it about the low 60s most of the time. I've never had this problem after about 15-20 batches. I don't know if this has been discussed here before. If anyone could give a clue as to what to do or not do, I'd love to hear it.

Hi - At the risk of beating a dead Clydesdale, I have a question about summer brewing. The temperature just rose drastically here in Chicago... For better or for worse, I'm preparing a batch. What confuses me is when I hear about folks who switch from lager to ale in the warmer months. If the lager fermentations are refrigerated, then what difference does the outside temperature make? I've been told many times that I cannot brew lager without an extra fridge. Is this true? I think I'll try the wet towel technique for keeping this brew cooler... How does one do something similar with a plastic primary fermenter? Thanks! Need a cold one in this heat! Jeremy Mirsky mirsjer at charlie.acc.iit.edu Return to table of contents

I'd appreciate any comments on this package (any bugs, DL:general annoyances, etc.) that anyone might offer. How does it compare to DL:other packages? Couldn't say anything about Brewer's Workshop as I haven't ever heard of it! But I *can* say something about SudsW4.0 which is a very handy piece of software for W3.1x/95. It is recipe based, and uses the DBase III file format. It's fairly complete, yet costs only $20 for the shareware fee. I'll mime or UUencode it to you if you are interested.

After reading a little bit about Silymarin, I purchased some extract at a local health food store (almost US$ 25.00 for 100!), and tried it out last night. After drinking a good bit of homebrew (extract, I'm still very new to this:) the only ill effects I had this morning were a bit of dehydration. I'm curious if anyone has any more info on Silymarin, and I'd like to know if many of you have tried it. Email responses are fine, as well as to the newsletter.

Date: Sun, 19 May 1996 09:01:53 -0400 From: TPuskar at aol.com Subject: Kegging I'm looking into kegging my beer and havea couple of questions. I'll be looking ofr kegging faqs at Stanford and other sites but wonder if anyone could comment on these questions from a real experience perspective. Here they are: 1. How long will keg beer last? My batches (in bottles) hang around for 3-4 months. Will beer in a keg last that long? Longer? 2. Related to the above question, once filled and tapped, do I need to keep the CO2 tank attached or can it be removed to another keg? 3. Do kegs require refrigeration after tapping? Can I store them at room temp and put them into the fridge when I want to serve from them and then take them back out to room temp until next time? Fridge space may be tight. 4. I see a lot of different prices for systems ranging from about $150 to near $200. I imagine the guages are the part that varies most. Any brands/manufacturers which are better or worse than others?

Date: Sun, 19 May 1996 11:00:20 -0700 From: dave at montara.cdf.ca.gov (Dave Sapsis) Subject: Cream Ale With Tom Castle's request in HBD 2033 for information on Cream Ale, I felt compelled to resubmit the following post I put together last summer. Somehow it never made it through. As yesterday was 101 degrees F (that's about 38 C for the rest of you) here in Sacramento, the timing seemed right. Also, those of you in Northern California are urged to locate its commercial clone from Coast Range Brewing Co. Their brewer, Peter Licht, and I have worked together on this and other recipes, and its out now under the moniker California Blonde (the public was confused by the cream part thinking it had dairy products in it or somesuch): ********* Some time ago Jeff Renner presented a recipe for Classic American Pilsner, along with a discussion of how and why this was an important beer style that needed to be recognized. Somewhat along those lines, however with a somewhat murkier history, is that of the almost forgotten cream ale. This is a style of beer that I particularly enjoy, and although there are current commercial cream ales available (eg, Little Kings, Genesee Cream) I am fearful that they do not fully represent the full potential for what this style can become. And although the AHA does recognize cream ale in its hybrid lager/ale category, I dont think that the parameters neccesarily allow what I have been developing (duh). Now possibly what follows is not a cream ale, but rather a new category, possibly called blonde ale for lack of a better term, but I strongly believe that this style has a place in brewing. What it is: blond; low to medium bitterness, very slight malt sweetness, moderate hop flavor and aroma; body low; high effervescence; low esters, no diacetyl. IBU's about 20, starting gravity about 1045, SRM 4-7. You can see that this only diverges from the general guidelines by the higher hop flavor aroma profile, but I think this is significant. For me, although these beers are often marketed as Pale Ales, they are both too light in color and lacking in bitterness to be Pale Ales. Those familiar with Triple Rock's Pinnacle Pale Ale know what I mean. Here's my recipe: (for 10 gallons) 16 lbs Great Western 2-row 1/2 lb H. Baird Carastan (~30 lov) Single protein rest at 50C (122F) for 20 minutes, water treated with 15 grams gypsum (I have quite soft water). Sacharification at 65C (149F) for 1 hour. Mash out and lauter to collect 12 gals wort og ~1040. Obviously, your extraction efficiency may be different than mine, adjust accordingly. Boil 90 minutes, end volume 10.5 gallons, og 1046 Hops: 70 minutes: 90 g Mt Hood (4.8 alpha) 5 minutes: 40 g Liberty knockout: 40 g Liberty For my levels of *perceived* utilization, this gets me around 25 IBU. Ferment with a neutral yeast that is low in diacetyl production (1056 works well, but I like Mendocino (New Albion), it just takes a bit longer to age and meld. Try to keep ferment temp under 70F. This is very important, for in my view, one of the principle elements that is requisite in this style is very low ester formation. I have found that mid 60's ferments are best. Obviously, large healthy pitches are a must to achieve quick, clean, and well attenuated ferments. Typically, my primary is over in 72 hours, at which time I rack to cornelius kegs, then after two days at68F, I slowly cool to 2C (36F) and lager for a minimum of two but prefferably 4 weeks. This ageing step appears quite important in generating the clean crisp flavor that makes this beer such a good hot weather drink. Now, previously, I'd never been much of a lawnmower beer kinda guy, but having moved to Sacramento from the foggy realm of Oakland, and a new residence with approximately 5000 (yes -- five thousand!) sq. ft. of lawn, I may be changing my tune. In any event, I think that you will find that this recipe results in a clean refreshing beer that is quite flavorful, and not altogether represented in our current litany of beer styles. Let me know what you think. cheers, dave sapsis Dave_Sapsis at fire.ca.gov Wildland Fire and Fuels Specialist CDF Strategic Planning Return to table of contents

The only possibility is from Contact East (1-800-682-2000 thanks Mike Kidulich). They sell bags for electronics but their objective is static electricity. There is no way to tell from reading their catalog whether the bags are food grade or oxygen barrier grade. I realize the inherent shortcomings of zip lock bags: they probably leak O2 through the zipper. My other option is to buy a vacuum heat sealer. I checked the local warehouse retailer and found one for $175 (Foodsaver brand). This question has been posted before but I saw few replies: Does anyone know of a source for zip lock O2 barrier bags OR know of a decent vacuum-heat sealer that costs less than the above mentioned model?

I need to know how much priming sugar to use per gallon to achieve a slight bubbly (not quite as much as champagne). Recipe below: 39.69Lb (4.76 Gal.) Water 7.25Lb (0.66 Gal.) Boysenberry/Blackberry 65 brix juice concentrate 8.00Lb Dextrose 0.50Lb Fructose 6 tsp Malic Acid 3 tsp Citric Acid 5 grams LALVIN EC-1118 Champagne yeast (Saccharomyces bayanus) This produced an OG of 1.093. I plan to dilute down a little bit at bottling time (another 1.25 Gal.). Reply to metlhead at ix.netcom.com or the Digest. TIA. Return to table of contents

I've been using a 1/4" chiller, with acceptable results. You can get a better seal on your hoses if you use small diameter automotive hose clamps instead of cable ties. I can crank the pressure way up on mine, and the hoses stay put -- no leaks. - -- Mike Uchima - -- uchima at fncrd8.fnal.gov Return to table of contents

Saw the Miller beer ad and asked" if the "heart of the hop" is so good, why aren't you using it" in my homebrews. So, what's "the heart of the hop"???? (and do they have other internal organs of distinction??) Stan White swhite at kodak.com Return to table of contents

I tried to weasle my way out of it (I hate public speaking and I'm in no way a RIMS expert) but the guy was persistant. Apparently the fact that I'm the only one in the club that owns a RIMS automatically makes me an expert, regardless of the fact that I've only brewed 3 batches in it, and all were single infusion mashes and thus under-utilized the full potential of the system. Anyway, I'm looking for some advise and tips from some of you more experienced RIMSters out there on topics and ideas for this presentation. Basically, I know that the pros are that (1) you can do multi-step infusion mashes, (2) you get a more even heat distribution in the grain bed, and (3) you get a clearer runoff sooner during sparging. The primary con seem to be the expense of building the contraption. I would also like to discuss some of the more arguable claims such as higher extraction efficiency (pro) and astringency from the recirculation (con). I'll also probably touch on the different types of RIMS (fully automated, electric heated, and gas heated). I'll be digging around the net this week trying to find more information. If any of you out there have any comments on the above topics, or if you can think of anything I've missed, I'd sure appreciate anything you can offer. Thanks!
