Glancing at the "Contents" I noticed "Water, High > Fuctose Corn Syrup, Dextrose......" and not much else. So this great > sports drink is basically sugar water. Not quite: the "not much else" include electrolytes which get used up during heavy exercise. Also, being mostly sugar water is just fine, since it is felt that glycogens burned during exercise are most efficiently restored if some sort of carbohydrates are consumed within two hours of exercising. "Runner" magazine advocated eating a meal within two hours of exercising, but most folks aren't usually hungry so soon. > Furthur, this 16 oz bottle contained > 100 calories. This got me thinking about the "beer belly". Would drinking > a "Milwieser" Light with about 100 calories cause any more belly than the > Gatorade I was currently drinking? It isn't just a matter of calories. The body metabolizes fats only very reluctantly, and this process is slowed down even more by the presence of alcohol. (by about thirty percent, recent studies have found). If you drink *only* one or two light beers after an hour of Racquetball, it will probably not matter; but if you have anything containing fats with it, the fat will tend to be stored rather than burned. Also, beer is a diuretic; it tends to make you lose water rather than retain it. Again, one or two shouldn't make much of a difference, but after you've just lost water working out, your aim is to rehydrate. (but a cold homebrew tastes great after racquetball!) > How does one determine the caloric content of anything? Is > this possible to do at home? One burns it, and determines the heat output. Or, one calculates the calorie based on the ingredients. I doubt that your home has the equipment to do either of these accurately. On another subject: Thanks to everyone who answered my questions on how to control mead sweetness. The most popular answer was to use enough honey so that even champagne yeast couldn't consume all of it; 3 to 3.5 pounds per gallon is about right to achieve a sweet mead. Making it both sweet and sparkling is tricky, since yeast does not always ferment honey consistently; you can try bottling before fermentation is complete, though.

One of my all time favorite brews was made using a pound of Maple Syrup in place of a pound of malt extract. I used it in a 'standard' ale recipe. (I have never made the exact same brew twice. I may not have consistency, but I have FUN.) I doubt you would want to ferment 100% Maple syrup. It is far too close to pure sugar. It would also be incredibly expensive. I would hesitate to go more than 25% Maple syrup. What I used translates to about 15%. As far as using Maple Syrup as flavoring, DO IT. I think you'll enjoy it. Jim Cowan Return to table of contents
Date: Tue, 12 May 92 06:34:23 PDT From: polstra!larryba at uunet.UU.NET (Larry Barello) Subject: Re: Calories Another point to keep in mind with the calorie counting: Appearently it takes about 23/100 calories of carbohydrates to convert them into FAT on your body. It takes only 3/100 calories to lay down fat (e.g. butter or vegetable oil). I am sure the numbers are generalizations, i got them from a recent issue of Longevity. So, regardless of the effects of alcohol on your metabolizm, if you eat fatty food you are going to be more prone to laying down fat. - Larry Barello Return to table of contents

Date: 12 May 1992 08:06:53 -0600 (MDT) From: JLAWRENCE at UH01.Colorado.EDU Subject: Newbie brewer questions, wort chillers I am a relatively new brewer, and have been reading the HBD for about 2 months, trying simply to get a grip on the terminology. I will be the first to admit that I do not spend a whole lot of time on brewing. With a full-time job and 2 small children, this has to be, at least for now, a hobby, not an avocation. My goal is to brew good (not necessarily superior) beer in a relatively simple manner. Anyway, I have some questions, which are probably pretty elementary to most of you contributors. However, answers would be appreciated. 1. I am using a single-stage fermenter. Pros/cons? Seems to work great, with no necessity for transferring to another container part way through the process. 2. I have a book called "Home Beermaking" by William Moore. It appears that he recommends pouring the hot wort into the fer- menter and cooling there. I usually cool in the pot, then transfer. Any comments? 3. Speaking of transferring, should I pour the whole pot into the fermenter, "sludge" and all, or should I attempt not to dump in that stuff? What is it, anyway? Is this the hot/cold break stuff I've been reading about? 4. I have cooled the wort 2 ways: by sitting it in a bath of cold water, and by simply letting the pot sit overnight. Haven't had any problems with contamination either way, with about 20 batches under my belt. What are the pros/cons of using a wort chiller? Seems like a huge waste of water, and living here in the West, that's of concern. 5. Miller also recommends boiling the priming sugar with water before mixing it in. Is this necessary? I've always just dumped it into the brew before bottling, with find results. 6. Does anyone have any guess on whether our mile-high altitude has any effect on thee specific gravity? Can't remember my high school chemistry. I tried a recipe this weekend and have a 5 degree higher starting gravity than expected. I got an order from William's last week with a special flyer inserted. They've got various stuff on sale through June 30, including an "imperfect wort chiller" for $21.90. It's billed as the same quality as their regular chillers except not as pretty. Phone (510)895-2739; P.O. Box 2195, San Leandro CA 94577. By the way, I use a pot designed for canning to brew in. Got it at McGuckins in Boulder, a terrific "we've got everything" hardware store. Thanks for your help. - JKL Thanks much for your help. Return to table of contents

I have made a couple of raspberry ales with surplus bright red raspberries from my backyard. In both cases, I pitched them early in the boil, so they were in there for an hour or so, by which time the raspberries were completely "dissolved" in the wort. I racked the wort in the fermenter, and all (or most) fruity residue settled at the bottom along with the yeast. The ale is still amber, little or no hint of raspberry _flavor_, but the aroma of hops and berries is out of this world. The head also has a slight reddish hue. I have read lately of people pitching their berries along with thei aroma hops. I will try this approach in a couple of months, when the berries are ripe! Robert Haddad Return to table of contents

Isenhour) Subject: lagering in cornelius kegs Kieran O'Connor <OCONNOR%SNYCORVA.bitnet>askes about Lagering in Cornelius Kegs >Can anyone out there give me a primer on how to do this? Some of my best beers are a result of lagering in cornelius or regular SS kegs. I usually don't prime, I just force CO2 into it at slow intervals at low pressure (as I recollect about 16 psi at 34 d F.) till it stops taking it (i.e. when I hook up the gas, the headspace is at 16 psi already). > How 'bout C02 buildup? I've never had a problem with it, if its fermented out pretty well (I only do this with classic lager style beers, so theres not a ton-o-unfermentables left like in a sweet stout:) >Is there a problem with sediment because they would be on their sides? I consider this an advantage, the yeast tends to stick to the sides of the cornelius keg and if you upright it gently it stays there. The yeast has such a shorter distance to fall, it makes for quick clearing, this may not be important depending on your lagering time. >How about aeration during transportation to the freezer (30 miles away)? I always hook CO2 to the pickup tube and blow the air out of the keg before I fill it. If you transport it then, what you will get is a small amount of carbonation (vrs oxidation). >How 'bout anything answers to anything else I forgot to ask? If you prime, be sure to put a little CO2 pressure (~5-7 psi) on the keg to 'seal' the seals, I've had trouble with the seating of the large 'O' rings leaking and killing the priming. If its on its side the beer should seal it but I dont take the chance. - John L. Isenhour isenhour at lambic.fnal.gov Return to table of contents
Date: Tue, 12 May 92 09:56:41 CDT From: gjfix at utamat.uta.edu (George J Fix) Subject: Caloric content of beer (George Fix) Walter Gude asked in HBD#878 about the determination of calories in beer. The following empirical formula is remarkably accurate, and widely used to check direct measurements. Let A, FG, and RE be defined as follows: A = alcohol content of finished beer in % by wt. RE = real extract of finished beer in deg. Plato FG = final gravity of finished beer. Then the number of calories per 12 oz. bottle is the following: (6.9*A + 4.0*(RE - .1))*3.55*FG . Since A and RE are generally not known to us, additional approximations are needed. The following are due to Balling, and have proven to be reasonable. Let OE and be defined as follows: OE = original extract (i.e., extract of finished wort in deg. Plato) AE = apparent extract (i.e., measured deg. Plato of finished beer). Then RE = .1808*OE + .8192*AE, and A = (OE-RE)/(2.0665-.010665*OE). To take Walter's specific case, first note that from Plato tables an OG of 1.045 is equivalent to OE = 11.25 deg. Plato, while a FG of 1.010 is equivalent to AE = 2.5 deg. Plato. Therefore, RE = .1808*11.25 + .8192*2.5 = 4.08 deg. Plato, and A = (11.25 - 4.08)/(2.0665 - .010665*11.25) = 3.68 % wt. We conclude that there are ( 6.9*3.68 + 4.*3.98)*3.55*1.010 = 148.12 calories in Walter's beer. Note that 61.5% come from alcohol, and 38.5% come from the residual extract. Errors in the formula for calories using A and RE will be under 1%. Errors in Balling's approximations can be as large as 3-5%. I am looking forward to Milwaukee for I know there will be a big HBD turnout there. Return to table of contents
Date: Tue, 12 May 92 10:26 CDT From: korz at iepubj.att.com Subject: Re: Diacetyl Bottling "as soon as possible, without letting the beer go through secondary fermentation" as Thomas suggests is not the right way to go (I feel). Either the sugars will all be used up by the yeast or not. If not, then beer grenades. What you need to do is to first choose a yeast that produces a lot of diacetyl. There is a sheet from Wyeast Labs that you should be able to get from your supplier that gives the approximate attenuation, diacetyl production and some other comments on each yeast. Then, when the initial fermentation has died down, get much of the yeast to drop out of solution by using finings, such as gelatine. Some of the diacetyl will be reduced, but the lower concentration of yeast will leave more diacetyl in the beer. Al. Return to table of contents

Date: Tue, 12 May 92 17:11:57 BST From: Conn Copas <C.V.Copas%lut.ac.uk at hplb.hpl.hp.com> Subject: Old Peculiar > I have made a stab at O.P. based on the Elbro Nertke Brown Ale > recipe from Papazian: > New Peculiar > 6.6# dark extract > 1/2# crystal malt > 1/4# black patent malt > 1.5oz fuggles 45min boil (pellets) > 0.5oz fuggles 10 min boil (pellets) > 2 tsp 'water crystals' > 1 tsp irish moss > Whitbread Ale Yeast > 1/2C black treacle A couple of constructive suggestions. First, what are we aiming for ? My answer would be that OP is distinguished by being an exceptionally bitter-sweet dark ale, with a very characteristic 'liquorice' after-taste. The original gravity (on draught at least) is around 60, and the alcohol content is around 5.5% by volume, meaning that it must finish around SG 20. Hop aroma is not especially pronounced. Another way to describe it might be to say that it is a scaled-up brown ale with compensating bitterness. The above recipe looks to me like it might make a dark ale which doesn't have the residual sweetness of OP. I would normally use at least 4 oz of Northern Brewer (English, seeded) with no late addition technique. Can't say how that might translate into US pellet Fuggles. People keep suggesting that OP relies for its character on treacle or molasses, but my personal opinion is that using sizable amounts of either will create a beer that takes forever to mellow out. The best way to get the liquorice character is to use crystal malt, and lots of it. I would normally use around 4 lbs in a US 6 gall batch (can't quote a colour rating, I'm afraid). Caveat - I have found from experience that I get an extract of around 8 per lb per gall for the crystal, whereas the textbooks all suggest that the theoretical extract is on a par with pale malt (ie, approx 30). For me, the extract has remained the same regardless of whether I have mashed, infused separately, or even (in desparation) boiled.

Secondly, he recommends using >yeast extract to assist fermentation, but the shop I ordered from >doesn't carry "extract" per se, but something they call "yeast >energizer" which they say is really the same thing, but most often >used to unstick stuck fermentations. Anyone got any feedback? you won't get much blowoff - only a little if you fill the fermenter all the way to the top (as recommended). yeast energizer works, but can impart a flavor (sharp, nauseating) into the mead that takes a long time (about 9 months) to settle out. If you're planning on letting this one age a long time (like you should, unless maybe you're making a sweet mead w/o any fruit), then use it. Ground up dead yeast also supplies the necessary nutrients to get yeast going, but that can also impart different off-flavors that don't go away with time. If you're making a sweet mead to drink young, I would use it instead of yeast energizer, though. You probably won't notice a yeasty note nearly as much in this type of beverage. By all means, use some sort of energizer, or else pitch a lot (3 packets) of yeast. It will take a while (> 2 mo.) to ferment as it is. Also, do not exceed, say, 1.020 initial S.G. Anything higher than this will take forever to get going, and never get out of the undrinkably sweet range. In My last batch of mead, I used 15 lbs of honey and 8 lbs of bluberries (for that exta "staining" power) to make 6 Gal of 1.005 must. I took it to my friend's house where it could ferment in the cool basement on a (hard) cement legde. I was extra careful in setting the carboy down, but still managed to crack a 6" hole in the side. Glug, glug, glug... What do you think of a spruce-flavored mead? I have a bunch of spruce flavoring (more than I'll ever use). - ------------------- Does anyone have any experiences using rye malt? I bottled my batch of Bock 'n Rye 2 months ago. One month later, the carbonation was just starting to kick in, and there was nice whiskey-like taste, but also quite a nasty aftertaste. Last night, I popped one open, and it seems to be mellowing nicely. bb Return to table of contents

Date: Tue, 12 May 1992 14:44 EST From: RRINGEL at LANDO.HNS.COM Subject: wheat beer, carboys, yeast, procedures Hello brewers! This last year has been a learning experience! I brewed my first ten batches and have improved my beer with each iteration - thanks in large part to the information I get from HBD. I remember my second batch - interesting flavor, nothing like I had ever tasted. Also, I wondered what the ring around the neck of the bottle was. But like a child that only a mother could love, I drank all of it. NOW I know better! Now I use liquid yeast, partial mash (spent grain goes into the garden), 5 gallon boil, IBU calculations instead of HBU calculations, glass at all times, 1 inch blow-off tube, secondary fermentation, pitch on top of the trub and rack off before fermentation starts, whole hops, bleach as a sanitizer, a 50 foot home-made immersion wort chiller, wide-range aquarium thermometers, and yeast starters. What's next? Stainless steel brew pot, full mash, digital PH meter, kegging system, yeast culturing, competitions, and lots of relaxing! I have a few questions about some current threads in the HBD, and a few of my own. First, when storing yeast slurry in the refrigerator for re-use, does it matter whether it is ale or lager yeast? It seems to me that the lager yeast will continue to be active and thus progress to autolysis much sooner than an ale yeast. John Devenezia supplied an interesting wheat beer recipe in today's HBD that called for a 180 degree steep of wheat malt. From what I know, I would conclude that no fermentables were added to the wort from this process. Is this correct? If this is true, then what flavor contribution does this make? While we are on the topic of wheat beer, how does one achieve the clove-like flavor in some of the commercial brands (Spatan, for instance)? Has anyone found a good way to cold-ferment a 5 gallon batch without using a refrigerator? I'm trying this right now, with batch #10. I set the carboy in a water bath with a wet towel draped over the top, and have a fan blowing air onto it. I also have a de-humidifier in the room to keep the evaporation as rapid as possible. While this seems to be working, it is eating alot of electricity. (Room temp 63, beer temp 55 and dropping daily) I am reluctant to use ice, because I would worry that the temp of the beer would fluctuate, thus hurting my yeast. Are there any better methods? Two of my carboys have developed little "crystals" on the inside that I can't get rid of. They are about the size of a small grain of sand, and are along the shoulder of the carboy. They are also grouped near the bottom. What are they, and how do I get rid of them? When the carboys are not in use, I fill them with a bleach solution (4 or 5 glubs from the bleach container). Is this some form of crystalized clorine? Now that I got started, I can't seem to shut up... That's typical when home brew is involved! -Rick Ringel (P.S.

Date: Tue, 12 May 92 15:56:56 EDT From: griggs at benjamin.tch.harvard.edu (griggs) Subject: CO2 tank pressure Just as a point of information, the tank pressure reading on CO2 tanks has little to do with the actual amount of gas left in the tank. This results from the CO2 being present in a liquid form at the bottom of the tank, evaporating to replace gas which is let out of the tank. The observed pressure is purely a function of the temperature and can vary from 500 to over 900 psi, depending on the tank temp. For this reason, suppliers of the gas sell it by the lb (literally, they weigh the tank before and during filling). In a 72 (F) degree room the pressure will remain at ~900 psi until all the liquid is gone, then the pressure will drop at a linear rate as the gas is used. The dropping pressure is a sign that the tank is almost empty and should be refilled. The only reason I can think of for not using the tank until it's completely empty is the danger of backpressure. The beer, exerting pressure of it's own, could back up through the regulator and into the tank. This would be bad for the regulator, the tank, and the beer ;). This actually happened to a gas pressure system in our lab, so I know it's possible. Keep on brewing... -Chauncey "wish I had a kegging setup" Griggs Return to table of contents

MMMMMaybe. . . . I tried a bottle of a friend's "Mappelbrau" (no umlaut but say "maple" anyway), which was strange enough that I can't remember whether I even *liked* it enough. His recipe was a light ale kit, plus too much maple syrup. Basically, it tasted like maple syrup smells, except it wasn't sweet. My! If you do this, I suggest you start with something stronger-tasting than a light ale, like maybe an imperial stout. And be conservative with the maple! And don't use processed syrup! (I am assuming that fermented Miz Butterworth would be at least as nasty as any other fermented substance with artificial ingredients.) And whatever you do, AGE IT! In months previous to my sampling, Mappelbrau had perplexed and nonplussed many people braver than I. Good luck and have fun, Jake. PS - Sorry I don't know how much maple syrup he used. I'd start with say half a cup and work from there. Reinheitsgebot <-- "Keep your laws off my beer!" <-- gal2 at midway.uchicago.edu Return to table of contents

It's called Heartland Hydroponics (1-800-354-GROW). A quick glance at their respective catalogs tells me that this "new kid in town" is out to topple Alternative Garden Supply (1-800-444-2837) from the throne of cheapest prices in town. Oooh! Maybe a price war will be looming on the horizon? I stand with pocketbook at the ready! chris Return to table of contents
Date: Wed, 13 May 1992 01:17 EDT From: S94WELKER at usuhs Subject: Re: Maple Beer Scott Weintraub asks about maple beer. I have read about the possibility fo such beer in Papazian, who basically says "it's not worth it." Then, when I finally met the man, another brewer was offering him a taste of the very thing...maple beer, with 20% of the fermentable sugar supplied by fresh Vermont Maple syrup (about $15 worth...1.5 lbs or a little less). I tasted it too, and the maple note was very prominent, but mixed poorly with the very mild hop flavor. The maltiness of the medium amber ale on which the beer was based was quite pleasant as a background to the malt. Charlie commented he would use almost no hops (I might suggest dry hopping only with an aromatic variety like Saaz or Hallertauer), and add sweetness with ~1lb of crystal malt. I think even more sweetness would be called for...try adding some unfermentable sugar (lactose, dextrin). I would also use a small amount of roasted barley to darken the color, improving the visual impression of the 'Mapleness'. The taste buds of my mind would avoid using black patent malt to darken--the smokier flavors (as compared to roasted barley) don't sound good mixed with maple. Good luck--let us know how it turns out! - --Scott Welker Return to table of contents
