Hi, folks, I thought I'd post this to put a smile on y'all's faces or even a laugh. Here it is: A Pub With No Beer Well, it's long time away from your kendrid and all, With a campfire at night where the wild eagles call. But theres nothing so lonesome, so dull, or so drear As to stand in the bar of a pub with no beer. Now, the public gets anxious for the quota to come There's a faraway look on the face of the bum. The maid's gotall cranky and the cook's actin' queer, What a terrible place is a pub with no beer. A stockman rides up with his dry dusty throat, He presses up to the bar; pulls a wad from his coat. But the smile on his face quickly turns to a sneer When the barman says suddenly: "We're plumb out of beer." There's a dog on the veranda for his master he waits But the boss is inside drinking WINE with his mates. He hurries for cover and he cringes in fear, It's no place for a dog at a pub with no beer. Old Biddy the blacsmith for the first time in his life Has gone home cold sober to his darlin' wife. He walks in the kitchen she says: "You're early me dear." Then he breaks down and he tells her that the pub's got no beer. Oh, it's long time away from your kendrid and all, With a campfire at night where the wild eagles call. But there's nothin' so lonesome, so dull, or so drear, As to stand in the bar of a pub with no beer. It's Long After Ten At the pub on the crossroads there's whisky and beer, There's a brandy from Cognac that's fragrant but dear. But for killin' the first and for raisin' the gout, There's nothin' at all beats a pint of good stout Drink it up, man, it's long after ten. At the pub on the crossroads I first went astray, Where I drank and I'll drink for to fill Gallway BAy. Goin up in the marnin' I wore out me shoes goin' up to the cross for the best o' good booze Drink it up, man, it's long after ten. Some folk o'er the water think bitter is fine. And otheres, they swear by the juice of the vine. But there's nothin' that's squeezed from the grape or the hop Like the black liquidation with the froth on the top Drink it up, man, it's long after ten. It's Guinness it's Porter that has me this way, For, 'tis sweeter than buttermilk and stronger than tay, (tea) But when in the marnin' I feel kinda rough, Me curse on Lord Ivy who brews the damn stuff Drink it up, man, it's long after ten. I've traveled in England, I've traveled in France. At the sound a' good music I'll sing or I'll dance. So, hear me then, Mister and pour me one more, If I canna drink it up then throw me out the door Drink it up, man, it's long after ten, Drink it up, man, it's long after ten! I hope you guys enjoyed it. As you can see, this second song is where I got my sig from. A health to ya Alex <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> Some folk o'er the water think bitter is fine, And otheres, they swear by the juice of the vine.

Date: Mon, 18 Dec 95 12:25:03 -0700 From: gmccarthy at dayna.com (Gary McCarthy) Subject: Re: CO2 Solubility, Saturation Tom Williams writes: >Is there a difference between "saturated with CO2" and "carbonated"? I am only speculating: It has been postulated in the HBD of late that all the fermentable sugars are eaten up in about 2 days. If that is true, and then: 1) the beer has to be carbonated, which none of my beers are carbonated after two days, or 2) the beer is not carbonated, ie the CO2 has not "super-saturated" the solution. Thus the CO2 is just hanging around in solution looking to escape to the headspace, into a lower pressure area. After the headspace fills to >1 atmospheres, the CO2 looks for a lower pressure area, ie the beer this time. The pressure in the headspace forces some CO2 to dissolve into the beer, and over a period of 2 - 4 weeks, the beer becomes carbonated because of the super-saturated solution of beer and CO2. You know, everyone, I don't really care about this issue. All I know (for sure) is that I put some wort (gyle, right?) into my uncarbonated beer, bottle it, and 4 weeks later the beer is carbonated!!! Sure we want to know the correct mechanisms and order to the science of beerology, but I, for one, feel that we've wasted a lot of bandwidth on this subject. Not that I have not contributed to the wasted bandwidth, but I tire of the subject. So I, for another, hope that we have exhausted ourselves, feel we understand the issues, maybe not agree with all the conclusions, but these things are what I have gleaned from the debate. But I say it has been a good topic, but I do grow weary of it. But feel free to carry on without me. Same goes for the Sam Adams thread!! Hey, come on over to my house and have a homebrew!!!

It's a brand called Singha, made in Thailand by the Boon Rawd Brewery. I haven't seen it in any of the recipes around the internet. There are some subtle flavors I can't identify, and I'm wondering if anyone has tasted this brand and knows what they might have used. Perhaps they are using some of the local common food ingredients, such as coconut or Jasmati rice? Return to table of contents

You should have >>bought kegs with a valve for doing this. (mine is a little ring in the >>center of the cap, which I pull to allow the pressure to escape.) Or just press the center of the gas-in poppet which does the exact same thing, just a little less convenient and from a point a bit lower in the keg (a bit more of a foam problem.) No big deal, IMHO, kegs w/out these things are not a problem. >There is also a lot of folklore about length of line from keg to tap, >magic black line, and maybe some other things. I haven't ever >>experimented with these, but I know I have gotten foamy beer from other >>people's kegs with various lengths and colors of line. OK, I never heard anything about the color of the lines, that certainly would be foklore. OTOH, line length is very important. It's been discussed here to death already, but basically the longer the serving line, the higher serving pressure you will need. There is a big difference between the carbonation in the beer and the serving pressure. Too much serving pressure will cause problems for properly carbonated beer. I'd suggest letting out most of the pressure and trying again. If your beer is still much to foamy, you should let out all the pressure, then shake the keg which will create some pressure as the co2 comes out of solution. Keep doing this until the pressure and carb level is right. You may have to let the foam settle between cycles. Good luck. - --Brian Pickerill, Muncie, IN Return to table of contents
Date: Mon, 18 Dec 95 13:15:38 PST From: "Bryan L. Gros" <bgros at mindseye.Berkeley.EDU> Subject: mocha beer A long while back I asked for opinions on using coffee and chocolate in beer. Here's a summary of the reply. First, though, is not to forget about the significant bitterness added by both cocoa and coffee. Be sure to use a beer with a fair amount of maltiness to balance this added bitterness as well as the hop bitterness. People are not generally used to a chocolate flavor without an accompanying sweetness. CHOCOLATE I have added 1/4 cup cocoa powder to the primary of a porter. The beer had a chocolate aroma, but little flavor other than bitterness. Nate Mead used chocolate in a beer, presumably baking chocolate. He said it (probably the butter fat) left a white film around the carboy and the bottles. The beer was very chocoaty though. Mark Mierzejewski used 6 oz. cocoa powder at racking time (secondary?) and 2 4cup pots of espresso at bottling time in a mocha java beer. He said it was great, but he didn't count on the added bitterness. Chris Vyhnal used baking chocolate and said the oils ruined the head. The chocolate had no effect on taste, though Guy Mason said thumbs up on Charlie Papazian's Goat Scrotum Ale, which uses baking chocolate. John DeCarlo used cocoa powder once and had it clump. He also used baking chocolate and it "sized" on him. COFFEE John DeCarlo used 1/4 pound of unground french roast in the secondary for a week. He said this was way too much: he got carbonated coffee with a hint of beer taste. Dave Draper added 2 tbsp of grounds to the last 5 or 10 minutes of the boil. In a second beer, he added a large mug of brewed coffee to the primary at pitching time. Both ways worked well for him, giving a subtle coffee flavor. He used Wyeast 1084 for both beers. (low attenuation) Mike Cinibulk commented that boiling coffee (which you would do if you add grounds or coffee to the boil) is never advisable. Add brewed coffee to the secondary or bottling bucket. Another responder echos this sentiment and commented that he or she heard that Red Hook was going to make a coffee beer this way. Jeff VanDeusen wrote that he tried the Mocha Java Stout from the Cat's Meow II and it was "heavenly". He says a significant amount of aging is needed, up to 10 months. ***** There you have it.

Date: Mon, 18 Dec 1995 16:51:59 -0500 From: TMartyn at aol.com Subject: SABCO Racking/Wyeast 1214 Happy Holidays All! Following up on my post of the responses to my question about racking from a SABCO 1/2 barrel boiler, I did brew this weekend, using a fine nylon mesh bag for the pellet hops, and whirlpooling and letting settle for 10 minutes for the whole hops. With a scrubbie on the end of the pickup tube, the wort ran off BEAUTIFULLY. I still plan to extend the pickup tube and turn it toward the side of the keg, just in case. Thanks again to all who responded. Next question. I'm looking for feedback on the behavior of Wyeast 1214 Belgian Abbey yeast. Please don't bother telling me I should have used something else - it's already pitched. How low can I go for temperature. I want to hold below 65 degrees to minimize the banana notes - at what temp. will she go to sleep? Also, the kraeusen on my 1 qt starter looked *funny* - not thick, but rather thin and gassy looking - is this normal? Any replies by email greatly appreciated.

Subject: Kvass/Kwass From: duncan at vt.edu Date: Mon, 10 Jan 94 10:35:28 -0500 Sounds like an interesting experiment - was the product drinkable at all? For the sake of comparison, here's a recipe for "Kwass" taken from "The Compleat Anachronist Guide to Brewing" (Compleat Anachronist #6), published by the Society for Creative Anachronism: ---------begin quote----------- Kwass (Yield: 6 cups) 1 lb. day-old black bread or Danish pumpernickel 1 cup sugar 2 tbsp. dry yeast 1/4 cup lukewarm water 2 tbsp. mint leaves or 1 tbsp. dry mint 2 tbsp. raisins Dry the bread and then chop it into coarse pieces. The add the bread to six quarts of boiling water, remove from heat and cover with a towel. Set aside for eight hours. Then strain the mixture through a fine sieve into another large pot, extracting as much liquid from the bread as possible. Discard the bread. Add the yeast and 1/4 tsp. sugar to the lukewarm (110-115 F [43-46 C]) water and stir thoroughly. Set this aside for about ten minutes in a warm place and then add the yeast mixture, the remaining sugar, and the mint [to the 6 quarts of bread-water], cover again with a towel, and set aside for about another 8 hours. Strain the mixture again and bottle in a gallon jug or several quart-size bottles. Fill the bottles 2/3 full, then divide the raisins evenly among the bottles. Cover each bottle with plastic wrap secured with a rubber band. Place in a cool spot for three to five days, or until the raisins rise to the top and the sediment sinks to the bottom. Carefully decant the clear amber liquid [picking out the raisins?] and rebottle in clean bottles. Refrigerate until ready to drink. ----------end quote-------------- Sounds interesting, although I've never tried it. "Dry yeast"? I suppose bread yeast (yech!) would suffice, but I'd use ale yeast in my own typical overkill manner. Evidently, this version is not meant to be served carbonated, but in a second recipe the author directs you to bottle the mixture as soon as you see gas bubbles rising from the fermentation (of course, he also complains of the bottles building up so much pressure that the corks were extruded throught the wire cage - can you say "kwass grenades"? I knew you could). Further recipes on the making of Kumiss (fermented milk) <shudder> and Kefir (fermented buttermilk - which I have tried to make and do not recommend for the weak of stomach).

Date: Mon, 18 Dec 1995 21:30:56 -0500 From: dkerfoot at freenet.macatawa.org (Douglas Kerfoot) Subject: Heater/Fridge Temp Controller Plans I've recently designed and built a temperature controller that can control either a refrigerator OR a heat source. It uses the Radio Shack Thermometer Module (part # 277-123) that some folks have inquired about in the past. Its range is -40 to +120 F so it won't work for a rims system. What it will do is allow you to keep your beer at the desired fermentation/serving temp regardless of the ambient temp. Right now it is keeping my beer from freezing in my garage refrigerator. (I'm in Michigan, the fridg is unplugged while a light bulb provides the heat) You can build it with Radio Shack parts for between $30 and $55, depending on if you have any basic components laying around. It's not as cheap as we homebrewers would like, but Brewer's Resource sells a functional equivelent for $90. It will probably be 2-3 weeks before I can get the whole thing organized. If alot of people are interested, I will archive the plans. If not, I will save the effort and have a beer instead. Please respond by private e-mail to save bandwidth.

The info is timeless even though it may not help the poster..... >Date: Wed, 15 Nov 1995 19:07:05 -0500 >Dave Ebert wrote: <<Secondly, if Santa gets me s JS mill I'll want to motorize it.>> Rather than trying belts & pulleys, it might be simpler for you to find an appropriately sized "gear motor" (motor w/integral reduction gears)... I hate to argue with a happy customer but my experience is that sooner or later, I will hear from him with some weird problem. Hundreds (if not thousands) of MM's have been motorized and the only ones I have ever had any complaints from are people who have used gear motors. They have had drive shafts fall off, gears stripped and all sorts of things that just can't happen if you use a large pulley on the mill and a small pulley on the motor. Belts and pulleys are forgiving but gears, chains, sprockets and direct couplings are not. The problem with gear motors is that the power must be transferred to the mill on a one to one basis with no opportunity to take advantage of the leverage obtained with pulley ratios. As a consequence, so much tension is required to drive the mill that stresses are developed that eventually snap off the shaft. Even if that does not happen, foreign objects getting into the mill can cause catastrophic damage whereas a belt will simply slip. I have been tempted to re-write the guarantee to exclude gear motors but would ratherjust caution against using them. js Return to table of contents

I started subscribing about three weeks ago, and find the HBD very informative. Thanks to all for a job well done. I recently did my first batch of homebrew. It is an Irish Brown Ale, prepared from Mountmellicks hopped malt extract (4 lbs), 2 lbs Muntons Plain Light DME, and Wyeast 1084 Irish yeast. After I somewhat belatedly read the instructions, I noticed it said to add hops for aroma. Being too late to add them at the end of the boil (the beer is now fermenting), is dry hopping a viable alternative? I was planning to rack to a glass secondary anyway, so this is not a problem. Is there any risk from a bacteria standpoint? What kind of hops should I add if I use this method, and how much? I do like a hoppy brew. Am I going too far for a first effort?

Date: Tue, 19 Dec 1995 12:29:19 +0100 (MET) From: Carl Etnier <Carl.Etnier at abc.se> Subject: What temperature does beer freeze at?/HBD police I am going to move very soon and take with me a number of cases of homebrew that I haven't had time to drink up. Now I have discovered that the rental moving van I thought I had reserved is really a flatbed truck. And it turns out that it is very difficult here to find a van with a heated freight area to rent. So I'm wondering if I should think of another solution, like a car pulling a trailer, with the beer in the car, or if I can get away with a flatbed or a panel truck as long as the temperature is no more than minus 2-3 C. If the lowest alcohol beer I have is around 5%, what temperature does that freeze at? If it begins to freeze, will that adversely affect the taste even if the freezing doesn't go so far as to burst the bottles (ice beer at home)? Other relevant information-- Beer's temperature in the house: circa 14 C Lowest alcohol beer type: pale ale Length of time in the unheated truck: up to 10 hours Smallest bottle size: 33 cl (11 oz) The rule of thumb I got from Sweden's government-run alcohol importer is to divide % alcohol by 2 to get the number of degrees below zero beer will freeze at. This is probably % abw--Sweden seems to be unique in using abw--but I forgot to ask. I'm sure there is a great deal of variation, depending on how much body the beer has and other factors. If you post, please Cc: to me privately, also. I'm leaving cyberspace until the day before the move and won't have time to go through all the back issues of HBD before the move. Thanks! - -------------------- There have been posts lately that contribute nothing but complaints that others write things that don't belong on HBD. One person in #1912 threatened to quit reading HBD. Go ahead, quit. We'll all just have to suffer the financial loss of your subscription revenue. ;-) Seriously, if there is a thread here that is particularly long and related to beer or brewing in some way, that is a sign that HBD is working. You don't have to be interested in everything here. Nobody is. Get a computer with a pagedown key. If there is only one person who seems to digress, I have found that polite private email is a kind and gentle way to show the person the error of his (it's always a guy) ways.

Anyone who has sailed long distances with a barrel will remember why. The motion polishes the inside of the barrel smooth and pitch would be rubbed off.

If you are going to inject steam from a conventional boiler you have a few *minor* problems. 1/"water hammer"-low spots where condensation can collect should be avoided. 2/"wet steam"- all boilers without superheaters produce about 98% steam and 2% water droplets. To vigorously boil 20 litres for 90 minutes you are going to use about 3kgs of steam. That is about 60 grams ( 0.06 litres ) of boiler feedwater. 3/ Feedwater-if your feedwater is untreated, it contains O2, all of which will end up in your hot wort. If it is untreated, the bicarbonate hardness precipitates as carbonate and concentrates by evaporation until about 3500 ppm when it causes violent foaming and "carry over" into the steam line. This can be compared to the stable foam on beer. The foam may contain oils from the feed water "dosing" pump as well as concentrated minerals. 4/ If your feedwater is "externally" treated, it is softened to remove many mineral ions. This is the best situation. However it is often also "internally" treated, it may contain antifoaming chemicals, sludge treatment to prevent sludge becoming scale, and oxygen scavenging chemicals. It should also have a "blow down" device to remove some concetrated water as fresh water is added. This still leaves high concentrations of alkaline hardness and chemical additives. 5/Explosions- if you accidentally cause a sudden drop in pressure in your boiler with your plumbing, all the residual water and steam becomes "superheated" (contains much more heat than steam at that new pressure) and immediatly vaporises *much* more steam. 1 kg of water = 1 litre, 1 kg of steam = 1670 litres! You had better be able stop the pressure drop quickly or superficial injuries won't be a problem! 6/ Legality- you don't want to know how heavy the inspectors are! And you will be inspected. If your feedwater is *externally* treated only, you can do this. Contact a steam engineering business to buy a "parabolic plug" valve. These prevent rapid changes in pressure when flow controlling it. Set you automatic blow down to maximum. Run a carbon steel steam line back through your furnace to superheat your steam and thus dry it. The line could melt when not in use. The superheater should be *after* the flow control valve. Superheaters need unlimited room for steam expansion. This will help the boil as well, unsuperheated steam at 1 bar is 100C, no temperature differential to vigorously boil, just simmer. Though, when you lower the steam pressure you also automatically superheat it, it may be enough to compensate for line losses. Weld a section of larger pipe in your line with the thinner lines crossing over inside. This is a condensate and scale trap. It needs a little tap to drain it. Avoid low spots that may trap scale or condensate in your lines and cause hammer. Insulate your lines, for your protection, not efficiency. Blow a lot of steam through water and see if it tastes much different than unsteamed water. A filter medium will also give you some idea of the quality of your steam. Or, go to the "Brewery" and pick up my article on building a separate low pressure steam generator. This will soon have diagrams and pictures. Charlie (Brisbane, Australia) "OOPS!" Algis Korzonas.

Tom Williams asks: > A question to the Encyclopedia Brewtannica: Is there a difference > between "saturated with CO2" and "carbonated"? I would have guessed > that the former is the definition of the latter. "Saturated with CO2" means that the liquid has as much CO2 dissolved in it as it can hold at a given pressure. It is at equilibrium. A liquid that is "carbonated" has *more* CO2 dissolved in it than it can hold at a given pressure. It is NOT at equilibrium, but is instead SUPERsaturated. That is why it bubbles.... it's trying to come to equilibrium. ======================================================================== On another note, I talked with the owner of a beer & wine store the other day and I might have discovered a *legal* and very cheap source of SS sankey kegs for converting into brewing vessles. As many of you already know, some of these beer stores will "sell" some of their empty SS kegs. The problem is that they do not own the keg, the brewery/distributor does, so they are actually stealing from the brewery. And if you buy one to convert into a boiling kettle, you are buying stolen property. Well, the man that I spoke with at this beer store confirmed this for domestic beers. However, he stated that many of the European breweries (such as some of the German beers) do not bother to reclaim their empty kegs and that 9 out of 10 end up being junked. So he was more than willing to sell me one for just $15. Now this sounds like a great deal, assuming what he says is true. (Note: the European kegs are slightly smaller.. ~13.2 gallons VS the US 15.5). And he sounds honest, given that he will not sell the other kegs. Or is he just more likely to get caught selling a domestic keg? Does anyone have any thoughts or comments on this? Do many of the imported kegs really get trashed, thus making it legal for homebrewers to buy them from these beer stores?

People tell of cooling their hot wort down in 15 minutes or so. I pre-boil a couple of gallons of water and then cool it down to about freezing, or sometimes even freeze it in 1 gallon plastic jugs. I put my "boiler" on an ice/water mixture in my split sink. When the ice has all melted, I pour the cooled wort into my primary and either pour the near freezing water in , or I cut open the jugs and throw in the ice. I get my mixture down to 70F in less than 15 min. Am I doing something harmful, or is low tech really just a good? BTW, I have a Pilsner in the fridg at 38F(bottled two weeks ago). How long is the lagering process? It is tasting pretty good and has a nice carbonation now. What exactly is the lagering process? Thanx for any answers. Jim Hust Return to table of contents

In fact, my very first attempt was to make a 2.5gal batch since I only had one 16qt pot - it turned out fine but only made 1 case :-(. I now have a second pot and do split boils with great results.

However, I came across an old homebrew book by Beadle (sp?) which indicated that the bottles should be turned upside down to wet the cap seals and make sure the priming sugar distributed through the beer in the bottle. BTW - one of our cable TV stations, The Learning Channel ("TLC") recently aired a show entitled "The Pharoah's Gold". It was a very interesting documentary about a group of archealogists and brewers who got together to unearth info on how the Egyptians actually brewed beer 6,000 yrs ago. It included recovery of ancient earthenware jugs that held the beer, the scientists extracting the sediment from the bottom of the jugs and evaluating what was in the sediment, and combining this info with other evidence determining what they thought was an actual ancient recipe. They determined that the Egyptians used two grains, barley and a wheat (arrow wheat?), mashed these and fermented them in earthenware pots. They may or may not have used corriander and another local bitter plant as flavoring. They brewers reproduced the recipe, and found it to be sweet (no hops bittering) but quite tasty. Another note of interest was that the Egyptians typically built brewery/bakeries, where both bread and beer were made. Just FYI - I get nothing from TLC other than a good education. Happy holidays.

Blue Moon Brewing is a subsidary of Coors being brewed exclusively by the F.X. Matt Brewing Co. (Saranac) in Utica, N.Y. They also unveiled a Pumpkin Ale, that was much better, IMHO, than Buffalo Bill's Pumpkin Ale. I think that there are two more styles that they offer, but their names escape me now. I see that they are advertising the beer in ASN, and Barley Corn, so we know what market they're going after.

Date: Tue, 19 Dec 95 10:29:17 GMT (Original EST) From: "Michael R. Swan" <mswan at fdic.gov> Subject: Hops toxicity in dogs I got a question in private email about this posting. Since other people may have the same question, I am posting the question and my response: >Can you tell me any more about what the article said in terms of >amounts ingested or hopping rates? ======================================================================== According to the article (which, in my haste, I forgot to credit to Edie Rehkopf in the November/December 1995 _Field Advisory News_), as yet, the toxic agent in the hops has not been identified. Without this identification, it is impossible to determine the absorption rate and the exact progress of the toxin. The author also states that there is no data yet on the amount of hops considered dangerous. In the author's case, her husband brewed fifteen gallons of Irish stout and strained out the hops into a bucket. The greyhound was found the next morning eating out of the bucket. No mention of whether it was whole hops or pellets but I assume whole hops given the reference to straining. Also, since it was a large batch of stout, I am assuming a fairly large amount of hops were in the bucket. However, it is not clear how much was ingested. By dinnertime, the dog was severely panting and running a 106 degree F temperature. She died thirteen and a half hours after eating the hops. Pretty scary stuff---especially since the Vet first told the woman that hops weren't dangerous to dogs. I guess this means don't dump your used hops in the compost pile if there are dogs around.

I don't own and have not read Miller's book, but all of the other literature I've read on this topic suggests that warm temperatures at the end of fermentation increases yeast activity and encourages the reduction of diacetyl, just as Noonan describes. Frankly, I don't understand Miller's position on this at all. Chilling the beer to 35F as he suggests will drop the yeast out of suspension, which would tend to *inhibit* the reduction of diacetyl. George Fix covered this topic in great detail in an article in Brewing Techniques about two years ago. If I recall, his conclusions pretty much agreed with Noonan. >is this "rest" worth worrying about (or using in >one's lager brewing process)? My understanding of the value of this rest is that it decreases the amount of lagering time drastically. Without the rest, it may require several months of lagering to get the equivalent level of diacetyl reduction that is attained during the two days the beer is held at 52F. If you're lagering in a fridge with an external temperature controller, it's relatively painless to perform the rest. FWIW, I step up from primary at 46F-48F to 52F by simply adjusting the controller 2-3 degrees roughly every 12 hours. Hold at 52F for 48 hours, then start reducing 2-3 degrees every 12 hours, until it's at 35F or so. Hold it at that temperature for a day or two, let everything settle out, then rack to secondary. Using this procedure, I usually get good results with 6-8 weeks of lagering time. This is somewhat strain dependant - some lager yeasts ferment so cleanly, W34/70 for example, that it's more like 4 weeks. Cheers, Jim dipalma at sky.com Return to table of contents

I used to do a lot of lagers by putting them against the basement wall , and covering with blankets, or a styrofoam cooler I cut so that it insulated the carboy on 3 sides with the carboy exposed to the cement floor, and wall. This gives a pretty consistant 45F temperature almost year round. It's not cold enough for a full blown lagering sycle, but it certainly has some lagering effect. I was using yeasts then that wouldn't go much below this temp then. Now I've got a fridge, and some real lager yeasts that can survive down to just a bit below 32F. Bill Crick Brewius, Eggnog Sum!

The first symptom to become apparent to an owner is heavy panting. Rapid heart rate will also be present, up to 200 beats per minute. The dog's body temperature may rise as quickly as 2 degrees F every five minutes." A possible coroboratory data point: I've noticed that if I consume enough beer, my body temperature rises also. If consumed in the presence of attractive females, my heart rate rises substantially. I'm not sure if this is related, but I have been known to howl at the moon on occasion. In any case, the effects on humans obviously needs additional research. I believe I'll get started right away...
