Raw unprocessed honey is readily available. It is relatively inexpensive as well.

The iodine was a yellow color on regular table sugar, and black as night on the dme. Thanks for the info on malting as well. I have to admit that while it may be problimatic, and a bit beyond my skill level, I am really excited to try. I have about 15 pounds of good quality barley now, and I think I'll start by trying to malt it as an experiment. >That's about it. I think you want about 3% water, which is >quite dry. I don't quite follow- could you please clarify what you mean by 3% water? Thanks a bunch, Adam Return to table of contents

And here's my two cents worth: Hops: Sierra Nevada Pale Ale. Classic Cascade aroma and flavor...Also, Bridgeport IPA for dryhopping Lactobacillus(sp?): Guiness Stout Sweet in the finish: Pyramid Broken Rake. I don't know if this beer will be out this year or not, but I fell in love with it last year. Yeast: Rolling Rock. Nuff said. Adjuncts: Dare I say Budweiser? Let it warm up a bit first to get the green apple smell. Well, I think that's enough ranting and raving for now. Return to table of contents

Date: Fri, 04 Oct 2002 08:46:47 -0400 From: Randy Ricchi <randyr at up.net> Subject: Malto-dextrin pwdr in a tripel Bill from Juneau asked about adding malto-dextrin to his tripel to help with mouthfeel because the beer finished at 1.010, when he was hoping for 1.015. Bill, Don't bother with the malto-dextrin. Your beer will have plenty of mouthfeel from proteins and alcohol. If it doesn't seem so right now, it will by the time it's ready to drink. Many of my tripels have attenuated to 1.010 and were fine. I prefer a well-attenuated tripel to one that finishes in the mid to upper teens. Return to table of contents
Date: Fri, 04 Oct 2002 08:47:21 -0400 From: "Shawn E Lupold, Ph.D" <lupolds at jhmi.edu> Subject: Sunlight, Hops, and Outdoor Brewing We all know that sunlight can skunk a bottled beer. Thanks to my wife's hatred for the wonderful aroma of homebrewing, I have been banished to the back porch. Since then I've brewed several hoppy beers, directly under the noon sun, and without a lid (due to the ever present boil over problem). So far I have yet to get any skunky characters. Believe me, I'm not complaining. My question is: Can anyone tell me why we get this skunking in a finished beer but not in boiling wort? P.S.- On the discussion of contamination, I boil and wort chill outside, with no lid, and have yet to experience any contamination (knock on wood). Even with rain falling into the chilled wort! I think the key to this is a big yeast starter. Return to table of contents

Shepherd Neame's Spitfire and Bishop's Finger (always wondered where it had been) often reek of diacetyl, but I don't know if it's reliable. You might check. I can't enjoy either when it's strong.

Date: Fri, 4 Oct 2002 09:44:22 -0400 From: "Dan Listermann" <dan at listermann.com> Subject: Malting & Malto Dextrin Addition Alan McKay, discussing malting, asks about the way rootlets emerge from barley corns. The rootlets sprout directly from one side of the corn. The arcospire forms at the same end, but goes in the opposite direction from the rootlets sliding under the husk. The degree of malt modification is gaged by how far along the corn's length the arcospire has been allowed to progress before kilning. Bill in Juneau asks about adding maltodextrin to raise final gravity. Very little malto dextrin is fermentable so it can be added at any time including at bottling. There is no real "need" to boil it any more than there is a "need" to boil priming sugar unless you have reason to believe that it is contaminated somehow although boiling, or at least dilution in water, does make mixing easier. To raise the final gravity from 1.010 to 1.015 for five gallons will require about 5 points * 5 gallons / 45 points per pound = .36 pounds - about a third of a pound or a cup's volume.

I have made a hot water extract of dark malt in the past to darken an anemic looking brew, so I would think that cold extract would work fine. >it looked darker when i was filling the fermenter etc... >i dont get it Don't forget that suspended yeast can make wort/beer look a lot lighter. You might want to wait until it clears to make a color adjustment. Here is Mary Anne Gruber's cold steep technique from the Briess Malting Co. September-October 2000 newsletter" at http://www.briessmalting.com/tips%20from%20techs/coldwater.htm xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx "Tips from the techs: Cold water extraction eliminates tannins: "Within minutes after adding a highly roasted specialty malt to the boil, color and flavor is leached. Unfortunately, if the boil is too rigorous or long there's also the risk of leaching tannins from the husks of the kernels into your beer-causing an astringent or husky flavor which is undesirable in many styles. Cold water extraction can eliminate that problem, according to Briess' Technical Services Director Mary Anne Gruber. "By 'cold' I mean room temperature," Mary Anne explained, "and plan ahead. Start steeping the specialty grain the day before you brew and let it steep overnight-for 12-18 hours." Steep with sanitized water-enough to cover the grain plus several inches. After the steep is complete, the extract can be added either at the boil, the extract and grain can all be added so that the spent grain will be collected with the rest of the trub. "If adding the extract to the fermenter, decant the extract then, if necessary, add some sanitized water to the spent grain and decant again so as not to lose any of the extract that you've steeped. Mary Anne recommends using a coarse grind if you choose cold water extraction. Since there is no enzyme activity, "you're not going to achieve much more with a fine grind," she advised. And it's going to be more difficult to remove the spent grain. "Cold water extraction takes more time," Mary Anne continued. "But it achieves more flavor from a highly roasted malt." Highly roasted specialty malts domestically produced by Briess Malting Co. include: Caramel Malts, Victory, Special Roast, Chocolate, Dark Chocolate, Extra Special, and Black Malt. We also make Roasted Barley and Black Barley." Hope this helps. Jeff - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at comcast.net "One never knows, do one?"

Found it in the mix drink section. It is larger grains than table salt but not as large as some pretzel salt I have seen.

Date: Fri, 04 Oct 2002 11:18:01 -0400 From: Marc Sedam <marc_sedam at unc.edu> Subject: cold steeping and using a coffee maker for brewing John asks about bumping up the color in his brew after the fact... I have a pretty straightforward suggestion which should work. 1) Get some dehusked Carafa III malt. I just used a POUND of this in 5 gallons of schwarzbier and it was a wonderful flavor. For your needs a pound may be too much. But four ounces might work well. You want the color but not as much flavor. 2) Four ounces (by weight) is convenient. The beauty of the Carafa III malt is that when you crush it it looks like coffee grounds. You can, in fact, grind it in a coffee grinder since there's no husk and no worry about extracting husk tannins. Strangely enough, four ounces is a volume which will conveniently fit in a normal 12 cup coffee maker. See where I'm headed... 3) Make a pot of Carafa coffee! Put the ground Carafa in the filter and run a pot of coffee. Pour the contents into your fermenter when cool. If you're worried about diluting the beer, add some brown sugar (half-pound??) to the Carafa coffee to try and match gravity. I've done this with porters (though not with carafa) when they weren't roasty enough and it works great. Also a great way to make extract + specialty grain brews. One pound of specialty grains would be four pots of "specialty grain coffee" which can then be used to help dissolve the malt extract without scorching, since the coffee maker will produce liquid around 170-190F. I've also run water through a coffee maker to make some quick sparge water on the fly (if I've miscalculated). Also great for extract+specialty grain brewing if you have too much grain to use the coffee maker without getting mad. Just remember that this is only useful for grains which don't have enzymes and the hot water steep is to get the "goodies" out. You will not "extract" (nyuk, nyuk) any value out of this process using Munich, pale, pilsner, vienna, and other enzymatic malts which require mashing.

Date: Fri, 04 Oct 2002 08:21:58 -0700 From: "Michael O'Donnell" <mooseo at stanford.edu> Subject: Oxygen regulator > >But the fact is that O2 is commonly used in welding, Exactly right. If you go to a welding store, they usually sell you all the O2 you want without question. They are a good place to get CO2 for kegs too. You don't need medical-grade O2 for brewing or most other applications. The difference between medical and welding grade is not in the quality of the gas but in the quality of tank-handling and record-keeping. As has been discussed (beaten?) to submission on this list (or try a scuba-diving list if you really want flying sparks!) the chance for contamination in welding grade is very low. Certainly nothing to worry about if you aren't actually breathing the stuff... and many divers breath welding grade underwater all the time to save money. As for a regulator, you can pick one of those up at the welding store as well, they may even be able to repair your old one. A new one is probably around $40 (from http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=35225 for instance ). The disposable oxygen tanks people have mentioned here are available at most hardware stores... look in the section that has propane torches. A large store might even have replacements for the little regulators to operate them, or you can find them at most homebrew stores. cheers, mike Pacific Grove, CA Return to table of contents

Date: Fri, 4 Oct 2002 14:14:18 -0400 From: "Michael Hackney" <mhackney at micromationsciences.com> Subject: Soft or Hard Water I recently moved from city water (Cherry Hill) to well water in Shamong, NJ. While mashing with Cherry Hill water, I never gave to much thought to the water or the pH, considering the water tasted good and my extraction rates were very good. In Shamong, I know I have hard water that changes greatly once it goes through my ion/exchange water softener. In regards to mashing, as it relates to extraction efficiency, (keeping all else equal) is my best bet to perform a pH test on the water and adjust if needed. If so, are pH strips accurate enough to obtain these results and what additives and how much of it do I add to the water to compensate to put the pH in the correct range.

Well this makes sense. I wonder if the GFI will operate with the SSR, perhaps without all the desired safety aspects. Operate, as opposed to being not acceptable. Would it be possible to place a resistive load in place of the contactor coil, with the SSR drive tapped off in parallel? My real question is where can one buy a 240 volt GFI for less than the cost of a conical fermenter.

Date: Fri, 4 Oct 2002 14:04:47 -0700 (PDT) From: John Sarette <j2saret at yahoo.com> Subject: Steam Clean? It occurred to me as I heated 7 gallons of water to boiling on my gas stove to sanitize my new affordable conical fermenter (thanks to my lovely and non-beer drinking wife) That steam might be the way to go to clean and sanitize my now all stainless and plastic brewing equipment. I would not want to use bleach in my new conical as it might corrode the spigots. I know from reading your discussions that star san, idophor and PBW are options but they are only available in small quantities locally or by mail order. In either case the price is high. Steam should do the trick but what steam generator should I use? I'm thinking about the steam buggy for about 60 usd but I'am wondering if any one has/is using steam to clean and sanitize. What should I take into account when purchasing equipment. I don't need much. I have stainless steel kettles from 2 to 6.5 gal and the 6.5 gallon conical fermentor. I don't intend to ever brew in greater than 5 gallon batches. Any experiences/suggestions will be greatly appreciated John j2saret at yahoo.com (in the old french quarter of the scandinavian state) Return to table of contents
