Happy Holidays, Santa was very nice to me, and left a 10 gallon gott under the tree this year. Now i have decided after reviewing numerous posts to construct a copper manifold at the bottom of the cooler. my questions is a simple one, since the outlet is apporx. 1 inch above the bottom of the tun, instead of bending the manifold so that it lays flush to the bottom, can i simply use 3/4 inch flexible tubing to connect to the copper pipe. will the 170 degree temps affect the tubing and subsequent finished taste of the beer? I've seen a few products use flexible hose for sparge temps. but ive always stayed away from running hot wort through rubber hoses. am i just paranoid? And where are you guys finding "food grade sealant", i havn't seen tube 1 !! Thanks, Dan Fitzgerald djfitzg at vnet.ibm.com Return to table of contents

I would like to brew my own beer but have no idea of how to get started. In the area that I live I am unaware of any homebrew supply stores, the Public Library is limited on the information that they have. From what I have been reading in the past several issues of the Digest, there are many different ways to brew beer. If anyone would be willing to share their knowelege of the hows, whys, and wherefores of brewing I would much appreciate it. Thank you in advance.

Date: 27 Dec 94 08:10:57 CST From: Collin A Ames <C-AMES at vm1.spcs.umn.edu> Subject: Rehi and a cry for help (sort of) Well met, and all of that! It's been...well...probably over a year since I posted last. My brewing sort of fell off due to fincancial woes and laziness, so I kind of stopped reading the list...you know how it goes. But, I finally got around to brewing a couple of batches recently. I tend to brew high malt content batches, usually around 8 lbs or so plus grains for color and flavor. The first batch ended up getting stuck at about 1.024, so I ended up using enzymes for the first time. Interesting effect and darned effective to boot. I bottled that one at about 1.006. The second batch is the one I need some advice on. It started at 1.050 or so and is down to 1.018, but has not stopped fermenting. I suspect it is a combination of using a liquid yeast (English Ale) and the fact that we now have a programmable thermostat in the house (temperature fluctuating daily between 66 and 70 degrees F). I believe I need to bottle, or at least move to a secondary fermenter, as it has been in the primary nearly 3 weeks now (bad, bad, I know). So, the questions: 1) Should I rack to a secondary fermenter (which would be plastic also, since I have not yet invested in a glass carboy) and let it continue at it's slow fermentation rate or; 2) Should I bottle now? If I do bottle now, should I use less sugar or nor sugar based on the assumption that if the yeast is still producing gasses, then there is still enough sugar in the wort to carbonate? Any and all advice is certainly appreciated. Thanks. Collin Ames c-ames at vm1.spcs.umn.edu Return to table of contents

Date: Tue, 27 Dec 1994 10:28:43 -0500 (EST) From: SAMEKT at VAX.CS.HSCSYR.EDU Subject: Flat beer I am new to home brewing. My first brew was an East India Pale ale that really tasted great. For my second brew I tried a Holiday Ale - flavored with nutmeg, cinnamon, cloves and honey. It has been in the bottle for two weeks and I tried one last night .... it tasted OK but there was only a small amount of carbonation. Will it carbonate more as it sits in the bottle ? I did keep it at room temperature (65 degrees) for a week before putting it in the basement (where it is a pretty steady 40 degrees). Any ideas ?

Date: Tue, 27 Dec 1994 11:05:19 -0500 (EST) From: eric addkison pendergrass <pendeea3 at wfu.edu> Subject: Low S.G. -- need remedy! Hi, I just brewed a batch of English nut brown ale, and followed the recipe exactly. However, when i checked the SG after adding water up to 5 gal, it as only 1.030 compared to the 1.040-1.045 which it should have been. My question is, how can I increase the SG? I don't have access to a brew store, and don't have time to mailorder extra malt. Could I place some permeable cover over my fermentor and try to evaporate it down to the correct SG (this would probably just result in a loss of alcohol, IMO)? What can I do? _______________________________________________________________ pendeea3 at wfu.edu * erpendergras at pollux.davidson.edu http://www.wfu.edu/~pendeea3 * pendgrss at whale.st.usm.edu [4.1] __________Watts Brewery________________________________________ Return to table of contents

Mark Witherspoon) Subject: Re: Grape Nuts Beer This is what I was told by the Gulf War Vets on how to obtain/make beer when it is illegal... Order about 3 tons of grape nuts. Soak in warm water for about an hour or so. Strain out the resulting mash. Add a few drops of a bittering substance, usually blue curacco liquor to the boil. Cool Ferment with yeast, what ever kind of yeast you can get, usually wine yeast. Produces about 3 tons of beer. Strangely tasting but decent. The Saudi's thought that the Americans were really weird for ordering 3 tons of grape nuts, but those in the field knew what they were doing... Mark Witherspoon Return to table of contents

The <sparging process is SLOW! It takes about 1 hour to sparge. Does anyone have <a better way to sparge without using high temperature pumps? Lautering takes about an hour, there's not much you can do about it. If you go faster, you will loose extract efficiency. Actually, one hour is very good. Usually 15 mins are required to clear the runoff, and a 45 min sparge is cruisin'. Micah writes (about high gravity brewing): <It also requires a great deal of care <and control to have good reasults. There are also compromises along the <line as well. This is a practice that homebrewers could use but I <would not bother. I would hope that hbers would use high gravity worts <to make barleywines and such and not try to copy icelightdraft. OK, we dont want to advocate post ferment dilution of icelightdraft beers, but how about making a English bitter or mild using a cast out wort of 17-18 Plato and diluting to 9-11 Plato? Wouldnt this result in a more complex, caramelly final beer than one brewed to the cast out OG of 9-11P? Tom asks: <Now my question. What's the collective netwisdom on propane cookers!!! <Things like Cajun cooker or King Cooker as examples. All of the lables say <they must be used outdoors and with adequate ventilation.Has anyone used the <m in basement (with windows open or fans going) or in a garage (with door <open) and lived to tell about it? Sure, the garage cajun cooker works fine. Also consider the Superb in Ill, they are 32,000 BTU heavy cookers. Will boil up to 20 gals of wort. Jim Busch Colesville, Md Return to table of contents
Date: Tue, 27 Dec 1994 12:29:02 -0500 From: TPuskar at aol.com Subject: Small Batch Brewing Thanks to everyone who provided input on small (1-3 gallon) batch brewing. The following is a summary of the comments received from Email and survey of several local brew supply shops.. Generally everyone felt that simply scaling down the amount of components on a direct basis would work fine. If a 5 gallon recipe called for 5 lbs of malt extract, use 1 lb for a one gallon batch. There are some exceptions worthy of note. For example, everyone felt that the normal amount of yeast should be pitched into a small batch. Since I use liquids for most of my 5 gallon batches, that could get expensive. I plan to use dry yeasts for any small batches. Another comment pertained to hops. Since small batches would probably be boiled as a full batch with little or no water needed to bring to final vlume (except to account for evaporation), hop utilization would probably be higher than for a 5 gallon batch which is generally boiled at higher concentrations. Several people mentioned that scaling up a small batch might not provide the same hoppy character . Since liwuid malt extracts are generally packaged in quantities for 5 gallons, most smaller batches would be easier to brew using DME. Other comments about accuractely measuring small quantities of materials (hops, extract, grains etc) were mentioned by several people. Again the comments pertained primarily to scaling up a batch once done at small scale. Temperature control was mentioned as a possible problem. Small volumes will be much more susceptible to environmental changes than a full carboy. On the flip side, it would be easier to keep a 1 gallon wine jug in a water bath to maintain temp control. Bottom line seems to be that scaling down to 1 gallon or so should provide a decent indication of what a full batch would taste like. Since Santa brought me a Corona mill for Christmas, I'll be on my way to my local brew supply to pick up a few pounds of a variety of grains. I can just see my basement lined up with Gallo jugs of some unusual brews. Return to table of contents
Date: Tue, 27 Dec 94 12:06:42 -0600 From: gjfix at utamat.uta.edu (George J Fix) Subject: Fermenter Geometry; NCYC 1187 The latest issue of Brauwelt (Vol.12, No.4, 1994) has an excellent article on fermenter geometry by Dr. Unterstein of Weihenstephan. His main conclusions are as follows: (i) The wort height to fermenter diameter is a crucial parameter which affects all aspects of the fermentation independent of volume. ( Note: The author derives a clever effective h:d for uni-tanks having a conical bottom.) (ii) The ideal situation is when this ratio is 1:1 or less. In no case should it exceed 2:1. (iii) Wheat beers are particularly sensitive to the h:d ratio, and for these beers it should not exceed 1:1. The first two items are completely compatible with results we found in test brews done a few years ago, and which Al communicated to HBD. We recently redid these tests using the Botham uni-tank (see HBD#1612), as well as redoing tests using a Cornelius keg. The former has an effective h:d ratio of 1.2:1, while the wort level in the latter was adjusted to get 4:1. The brews using the Botham tank were almost identical to what we got using squat 1/4 bbl. pony kegs. The main defect with brews fermented in the Cornelius kegs was their inconsistency. Some came out ok, but others not. The severity of the effects varied with yeast strain, but overall conclusion reached is that for best results the criteria (i) and (ii) should be satisfied no matter what yeast is used. (The details on these tests will be contained in my new book, which BTW has a new coauthor, namely Laurie Fix, who insisted on a new title, namely A Study of Brewing Techniques. It is scheduled for publication in June,1995.) The last item in Unterstein's article about wheat beers comes as a complete surprise. I conjecture this is a yeast strain issue, but I would be interested in hearing from anyone who has direct practical experience with this issue. I hope everyone interested in the geometry issue caught Cushing Hamlen's excellent post in HBD on Berard convection. Knudsen has pictures of these flow fields in various uni-tanks in his classic article "Tank Hydraulics", which appeared in MBAA Tech. Qr., Vol.15, No.3, pp.132-139. ******************* Dan McConnell writes about NCYC 1187 in HBD# 1612, and asks for more info. This strain is finding definite commercial acceptance. For example, both Hub Cap/Dallas and Hub Cap/ Vail are using it, and both won awards in the 1994 GABF. Dan's comments on its excellent mechanical behavior are spot on. I, on the other hand, do not personally find it to be a neutral strain in the sense of say Wy 1056 (BRY-96). It leaves a slight woody undertone which recalls the London ale strain, although it is different from the latter as Dan's comments indicate. IMHO it makes an excellent "wheat ale", rescuing these brewpub staples from their customary blandness. Opinions will differ on how well this strain does with other ale styles.

Date: Tue, 27 Dec 1994 13:15:03 -0500 From: Mdsj at aol.com Subject: Re: Propane Cookers Here in sunny Southern California, I use my cooker out on the patio for my midnite brews. I have also used it under the garage door (it rains once in a while), no ventilation but it's pretty windy here. I agree, it sure saves the marriage. I never have understood why everybody doesn't just love boiling WORT. I roll my windows down every morning when I go by the A-B plant in Van Nuys, just to see whats cookin'. There still is the problem of wort chilling (do you use the kitchen sink method? A garage sink or a counterflow chiller would be better) and cleen-up (the bottom of the pot gets black with soot. Again a garage sink would be in-valuable). As for how long it lasts? I have heard six brews, but I keep a second full 20# container as a spare (get one at Home Depot). I use a 20 qt pot on mine and it's very stable, but you have to get the flame just right. A bigger pot would be better, and would make more beer ;^).

It seams like allot of bubbling is going on as the >steam moves through the mash. True, a lot of bubbling does occur - but you are bubbling steam, not air. HSA (hot side aeration) is caused by _air_ (or, more specifically, oxygen), not steam. You have no reason to worry about HSA during steam injection. Kelly Return to table of contents
Date: 27 Dec 1994 14:50:19 -0500 From: "Rick Spada" <rick_spada at mathworks.com> Subject: Question on specific gravit Subject: Time:1:54 PM OFFICE MEMO Question on specific gravity Date:12/27/94 I recently brewed a bitter that had an original gravity of 1.040. After two weeks, fermentation had pretty much come to an end and I decided to bottle. I racked the beer into my bottling bucket, and took a gravity reading. It was 1.030 which I took to mean that it hadn't finished fermenting. So, back into the carboy it went, I pitched some more yeast, and put it in a warmer spot in my cellar with the thought that perhaps the beer was too cold for the yeast. Well, fermentation picked up a bit, and now a week and a half later, it appears that fermentation has finished. When I checked the gravity a few days ago, it was 1026. A few other items to add... I added the priming sugar between taking a sample for the gravity. I also filled and capped two bottles. I tested one last night and other than being fairly cloudy, it tasted fine, not sweet as I would have expected for an incomplete fermentation, nor was it overly carbonated. I used Wyeast's British Ale yeast. What I'm wondering is wheter there are other factors that would affect the specific gravity other than sugar? Does it sound like this beer is ok to bottle or should I let it sit a while longer with hopes that it will ferment a bit more? Thanks in advance for any help, and thanks for the HBD, it is a most valuable resource. - -- Rick __ Rick Spada _______________________ ricks at mathworks.com __ The MathWorks, Inc. info at mathworks.com 24 Prime Park Way http://www.mathworks.com Natick, MA 01760-1500 ftp.mathworks.com __ Tel: 508-653-1415 ___ Fax: 508-653-2997 _________________ Return to table of contents
