Several weeks ago we had several days of below freezing temperatures and some of my homebrew, bottled only a week, froze in my refridgerator which was in my garage. Several bottles broke, but the rest froze up. I've since gradually thawed out and is sitting in my basement waiting for a solution as to what to do from the net. I've tasted the beer and it tastes okay but is poorly carbonated, I mean POORLY. The beer is now aged 4 weeks in the bottle and little to no carbonation. Did the yeast get killed? Is there any way to recarbonate the beer ? Anything else I can Do? If it matters, the beer was a lager type malt extract and I was using red star dry lager yeast. Any suggestions would be greatly appreciated. Duane Smith Return to table of contents

Date: Thu, 10 Jan 91 07:45:40 -0600 From: Todd Enders - WD0BCI <enders at plains.NoDak.edu> Subject: Some Thoughts on Extract Efficiency Since this seems to be a popular topic these days, I thought I'd throw my 2 cents into the fire, and make a few conjectures as to what may be going on with poor extraction efficency. First, my normal extraction rate is pretty close to 30 SG points/gal/lb with a low of 29.3 and a high of 31.4 over the last 10 batches. I use the 'classic' 2 bucket lauter tun (inner bucket has 1/8 inch holes on 1/4 inch centers, as per TCHoHB), with sparge times running 90 to 110 minutes, depending on grain bed depth (i.e. amount of grain/batch). I crush my malt rather on the fine side, with the largest bits of endosperm (the starchy white part) being on the order of coarse corn meal, sizewise. No whole or half grains, but lots of large husk pieces. Now, why can't some people get better extraction rates than the 10-20 points/lb they get now? The lautering equipment is usually very much the same, so where is the loss comming from? 1. Mash too cold. You have to get the mash temp. above 149F to gelatinize the starches so they might be converted. If you are mashing at 150F, you'll want to be sure your thermometer is well calibrated. A few degrees of overshoot on the initial boost to starch conversion may be a good thing. 2. Malt ground too coarsly. This hurts on two fronts. Larger bits of endosperm longer to gelatinize, locking starch away from the enzymes, and not holding the sparge water in contact with the mash long enough to wash out the sugars efficiently. We do have to comprimise, since grinding *too* fine introduces problems with set mashes, husk tannins, etc. The ideal malt mill would powder the endosperm, leaving the husk in 2 or 3 large pieces. Idealy, sparging should take *at least* 90 mins with a 2 bucket lauter tun. 3. Not sparging enough water. For a five gallon batch and a relatively thick mash (1.3 - 1.5 qt/lb), You should have to sparge around 5-5.5 gal. If you are sparging so as to collect total runnoff of 5 gal., you're probably throwing extract away. This is all for what it's worth, and I'm sure some of you will take me to task on as few points, but hey, it works for me! :-) =============================================================================== Todd Enders - WD0BCI ARPA: enders at plains.nodak.edu Computer Center UUCP: ...!uunet!plains!enders Minot State University or: ...!hplabs!hp-lsd!plains!enders Minot, ND 58701 Bitnet: enders at plains "The present would be full of all possible futures, if the past had not already projected a pattern upon it" - Andre' Gide =============================================================================== Return to table of contents

Date: Thu, 10 Jan 1991 13:33:34 MST From: MIKBRO at zen.radiology.arizona.edu Subject: extract recipies please Hi, I have brewed 3 batches of beer and am interested in obtaining any recipies for extract-based beers which also use specialty grains. Please e-mail me any recipies which you particularly enjoy bearing in mind that I 1) am a novice brewer 2) am not interested in getting into all-grain mashing (yet) 3)am interested in brewing "unusual" beers 4)already own TCJOHB and thus already have C.P.'s recipies at my disposal and 5)am not a real hop fiend and tend to enjoy less-hopped varieties of beer.

Date: Thu, 10 Jan 91 20:34 EST From: George Bragg <George_Bragg at carleton.ca> Subject: pH meters My understanding of the matter is, the bottom of the electrode is a very thin glass layer, permeable to hydrogen and very few other cations (positive particles, for those who don't know). Inside is a little pool of an acid (hydrochloric?) and reference wires. The pool of acid's concentration of hydrogen ions changes by concentration gradients when placed in substances of varying ph's, and the reference wires pick this concentration change up and register it as a potential difference on the meter, which is interpreted as pH by us who don't know better :-). The tip of the electrode, if not kept wet, will allow the little H+ ions in the electrode pass out through the electrode, and the acid will dry up, meaning there is no reference point for the wires. This, of course, is a simple explanation - I learned it just today in analytical chemistry, and I could be misinterpreting a couple of facts, but it does sound right...

Date: Thu, 10 Jan 91 19:30:00 PST From: polstra!norm at uunet.UU.NET (Norm Hardy) Subject: Rinsing Bottles Not yet owning a dishwasher, my method for cleaning bottles has stabalized into the following steps: (1) Rinse real good after using, drain upside-down. (2) Since our present sink (until the wife puts in the smaller one to make room for the dishwasher) is large enough for 52 bottles (12 oz) or 40 bottles (17 oz), I soak the bottles in a bleach bath (2% or so) for a couple of hours. This removes the layers of film that accumulate. (3) Upon rinsing with the bottle jet sprayer and hanging on a bottle tree, I usually go the extra mile and bake the bottles at 300f for 60 minutes. Cool down takes awhile so I usually do the baking late at night or early in the day. Very few broken bottles, by the way. Oh, I remove all labels and foil before any of this. A large 10 gallon plastic bucket outside does the job holding the liquid and bottles. Norm Hardy Return to table of contents

Hi, I'm a new reader of the mailing list and thought I'd introduce myself. (I've finally figured out VI!!) My name's Chuck Morford, I live in Miami (Somebody has to...) and I've been brewing for 2 years...Mostly sweet stouts since those are my favorites, but I've brewed an occasional lager for my friends... Someone earlier mentioned a homebrew warehouse in Florida, could you please post an address? Also, I have a strange problem with the last batch I brewed. It was an American lager, and it had a haze when at room temp, but, when chilled it was crystal clear. Now, I've had the opposite problem before and I know how to cure that. But what can I do about it? The beer tastes fine at room temp and at 50 degrees, so I'm pretty sure it's not yeast...Maybe I should just "Relax". Return to table of contents
Date: Fri, 11 Jan 91 18:24:54 PST From: polstra!norm at uunet.UU.NET (Norm Hardy) Subject: Sam Adams the Maltster? I checked out a book from the library called "Brewed in America" by Stanley Baron, copyright 1962 by Little, Brown, and Company. It is a VERY detailed study of USA brewing from the earliest settlers on. On page 75 I came across the following that might interest you: "In spite of what most historians have said, however, it appears that [Samuel Adams] was exclusively a maltster and not a brewer. It was a traditional trade in the family." He was born in 1722, graduated from Harvard in 1740 and made efforts to enter the practice of law. But he tried instead to start his own business with a 1000 pound loan from his father, who owned a malting establishment. Sam loaned half of it to a friend who never repaid. Soon after the "default", Sam joined his father's business. Sam Adams, Sr. died in 1748, leaving Sam, Jr in charge. The malthouse was gone in 1763 as Sam Adams had by then become an active and dynamic politician. What is so interesting about all this is the hype that Jim Koch continually throws out in his marketing of the Sam Adams beers. The beers are fine, very good actually; so why the hype? Anyway, inquiring minds want to know. Norm Hardy Return to table of contents
Date: Sat, 12 Jan 91 18:35:44 CST From: "R. J. Pals" <uunet!inland.com!pals at uunet.UU.NET> Subject: Low OG question I'm a beginning homebrewer, and have been reading the digest for a few months now. I just started my first batch, a porter recipe from a mail order supplier. I'm using a blow-off system. The ingredients were 4 lbs of (liquid) hopped malt extract and 3 lbs of dried malt extract, plus some black patent malt and flaked barley which I put in grain bags and removed from the wort when boiling began. Anyway, the recipe says that OG should be 1.054 to 1.067. I only measured 1.033 at 84F, which corrects to around 1.040. Any ideas what went wrong? It seems like there should be little variance from the normal numbers - that is, X lbs of malt extract and Y gallons of water should produce an OG of Z - case closed, right? Is it possible that I didn't "stir" the carboy enough after putting the wort in and filling with water, i.e. could the liquid have been dense at the bottom and less so at the top where I sampled? I also checked the hydrometer in 60F water and it reads very close to 1.000. I'm trying not to worry about this.... Randy Pals Return to table of contents
