---------------------------------------------------------------------- Date: Mon, 10 Oct 2005 13:10:46 +0900 From: Boris de Mesones <demesones at gmail.com> Subject: re: Reading Kunze Carefully The first week of October 1998 I was sitting on the benches of the Brewing School VLB in Berlin, publishers of the book Brewing Technology by Kunze, with an English version under my arm. One of the first questions made by some German brewers was: - if we have a book like Kunze, why do we get so many photocopies before any lecture? Can we not just follow the text of the book?- Our teacher of Sudhaus (brewhouse) technology, and assistant of the Professor at that time, told us: -because it has several errors, it is not very reliable and information is not very complete, for example, look at the DMS reference-. Even though I used it as a reference for a few weeks, I decided afterwards to buy the German version because the English translation was not very good. Translations can be done in two ways, you translate literally or you translate the meaning of the phrases, the second one takes much more time to translate and it is much more expensive. In my opinion the English version is a mainly literal translation, you have to read it between the lines with German mentality.

Date: Mon, 10 Oct 2005 00:15:03 -0400 From: "Kyle Jones" <kjones1 at ufl.edu> Subject: RE: Mashing cool David Edge writes that he has been having trouble with his beer clearing when he mashes at 63C/145F. Dave, you're definitely below the starch gelatinization temp of 67C/152F, so you're not making a lot of the starch available to the amylase enzymes for "processing", and consequently those large starch molecules are causing your finished beer to be cloudy, and can also cause a problem with infection on down the road, as many of the nasties that infect beer love to latch on to starches. You can test your wort for starch conversion with iodine, but simply bumping up your temperature to 150-152 for a single infusion mash should still leave you with a moderately fermentable wort, and achieve almost complete starch gelatinization. Good luck. Kyle Return to table of contents
Date: Mon, 10 Oct 2005 04:41:15 -0700 (PDT) From: Brad Railsback <rails2bier at yahoo.com> Subject: Has anyone tried this recipe for cock ale? I just ran across an old home-brew book titled "Home-Brewed Beer and Cider" by Ben Turner. The recipe I found interesting as is followed: 1 imperial gal.(4.5 litres) medium-hopped malt wort of S.G. 1.044 Carcase bones, wing tips, tail, neck, and serving scraps of a plainly roasted chicken .5 pint (.3 litre) of dry white wine 1. Crush the bones and place them with all the chicken pieces in a bowl containing the wine. Cover and leave in a cool larder or refrigerator for 24 hours. 2. Pitch an active yeast into the wort, cover it and leave it in a warm place to start a vigorous fermentation. 3. Next day strain the wine into the wort, place chicken pieces and bones in a coarse nylon or muslin bag and suspend this in the wort. Replace the cover and continue the fermentation. The presence of some fat from the chicken will inhibit the formation of a frothy head but will not stop the fermentation. 4. After three days, withdraw, drain and discard the bag of chicken and continue the fermentation to the finish. this will take two or three days longer than usual. 5. Clear, bottle, prime, seal and mature for at least one month. This is a well-tried adaptation of the old country habit of killing, plucking, cleaning and flaying an old cockerel and adding the broken bones and flesh to a barrel of fermenting beer. The results are a very fine beer, well worth brewing. I take no responsibility for the above statements as I copied them from; "Home-Brewed Beer and Cider" by Ben Turner; published by EP Publishing, East Ardsley, Wakefield, Yorkshire, England in 1981. Would the wine be strong enough to sterilize the chicken parts or has most of the oxygen been used by the time you add the parts? Does anyone have any ideas why they used to add chicken parts to fermenting beer? Prosit, Brad Return to table of contents

It is Dixie Cup time again! and we will start judging the Dixie Cup XXII entries This Sunday. Please, come be a part of Dixie Cup and help us judge. We need beer judges of all skill levels to come and help out. Don't worry if you are not BJCP ranked. We will either put you on a panel with experienced judges or use you as a steward. Everyone can be a beer judge!!! Here is the judging schedule: 10/16 First round judging at Saint Arnold Brewing Company from 9 AM to 4 PM. 10/18 First round judging continues at Saint Arnold Brewing Company from 6 PM to 10 PM. (This judging session is contingent upon progress made on Sunday). 10/21 First round judging continues Noon - 10/22 Second round judging Noon - That's it! Please come out and give generously!

Date: Mon, 10 Oct 2005 17:57:27 -0400 From: "Haborak, Kevin" <kevin_haborak at golder.com> Subject: modeling Steve writes: "Not only do we have the extract gradient driving extract from grist to liquor, but we also have the liquor gradient driving extract from bottom liquor to top liquor. And I suspect that the two diffusion constants involved differ considerably." I have tried to stay out of this topic, but I had to correct this statement. Advection-dispersion-sorption is going to be the dominant mechanism of transport. Diffusion will have a negligible effect, especially from the top to the bottom of the column. Both problems are cases of chemical transport through porous media. So perhaps you guys should look into soil mechanics/chemical transport for the answer to the problem. Regards, Kevin H.

Date: Mon, 10 Oct 2005 17:25:11 -0500 From: Bill Velek <billvelek at alltel.net> Subject: New patent application for beer-like alcoholic beverage Just thought my brewing friends would find this most interesting. New Patent Application filed on 10/06/05 | #20050220935 for a beer-like alcoholic beverage, and process for producing the same. "A process for producing a beer-taste alcoholic beverage without the use of malt, barley, wheat, etc., including preparing a pre-fermentation liquid from raw materials of a syrup containing carbon sources, a material containing amino acids, hops, coloring matter, a foam formation/head retention enhancing substance and water; and fermenting the pre-fermentation liquid in the presence of yeast so as to form a sparkling alcoholic beverage. This process enables obtaining a beer-taste alcoholic beverage which has the same taste and appearance as those of beer and which is excellent in head retention." Agent: Oblon, Spivak, Mcclelland, et al - Alexandria, VA, US Inventor: Masao Oono http://tinyurl.com/e2kl5 ***** I don't know what this would taste like, but the inventor is apparently Japanese, trying to avoid Japan's heavy tax on beer and Happoshu, and appears to be quite serious; a Japanese patent has apparently already been issued or is pending. Although you can reach these from the above link, for your convenience I'm providing the following links to: ... full-patent description = http://tinyurl.com/dfzlr ... and ... patent application claims = http://tinyurl.com/cbshq In particular, see "fetal bovine serum albumen" in #10, below; that's really weird and brings all sorts of thoughts and questions to my mind, which I'll keep to myself -- at least for now. :-) Anyway, I've trimmed the claims page down a bit to its essentials, and have added some questions/comments in brackets, as follows: 1. ... obtained by producing a pre-fermentation liquid from a carbon source-containing syrup, a nitrogen source, hops, coloring matter, a foam formation and/or head retention substance ... 2. ... a flavor is added to the pre- ... or post-fermentation liquid. [I wonder what sort of 'flavoring' is available for post-ferm, considering that they are already using hops] 3. ... the nitrogen source is an amino acid-containing material. 4. ... the syrup is obtained from ... corn, potatoes, and rice. 5. & 6 ... the syrup contains a portion of the nitrogen source ... obtained from ... corn, potatoes, peas, soybeans, and rice. 7. ... the amino acid-containing material has an amino acid composition sufficient to enable fermentation with beer yeast. 8. ... hops are ... powdery hops, a hop pellet, a hop extract, and hop-modified products comprising isomerized hop extracts, hexahydro-iso hop extracts, and terahydro-iso-hop extracts. 9. ... coloring matter is selected from ... [snipped a bunch of natural and artificial coloring agents] 10. ... the foam formation and/or head retention substance is ... plant extraction saponin ["s."] substances such as soy s., Yucca s., quillaja s., tea s., and ginseng s.; proteinic substances such as albumen peptide and fetal bovine serum albumen; thickening agents such as xanthan gum, pullulan, guar gum, locust bean gum, carrageenan, pectin, acacia gum, tamarind seed polysaccharides, agars, tara gum, and gellan gum; and alginic acid esters. ["Thickening Agents"? Do you reckon that might be for 'mouth feel'?] 11. ... is a flavor that provides beer-likeness. [I wonder how close beer-"likeness" is to the real thing.] 12. ... food fibers that provide functionality are used. [I wonder what "functionality" means, and how fibers provide it.] 13. ... a herb that provides a characteristic taste is used. [I wonder what herb provides which "characteristic taste.] 14. A beer-taste alcoholic beverage produced by the method as claimed in any of claims 1 through 11. END OF CLAIMS. For cryin' out loud, just bribe some politicians and get the damned taxes reduced. ;-) Cheers, Bill Velek Return to table of contents
Date: Mon, 10 Oct 2005 20:17:44 -0400 From: Nathaniel Lansing <delbrew at compuserve.com> Subject: re:beer gun, + safale + efficiency ever tried the "beer gun", but it is not a CPF. It does have the co2 purge but no counterpressure; which I believe is the entire point of the exercise. If you want to try it that way, just stick a bottle filling wand on the end of your cobra head faucet and save a bunch of money. ////////// Safale US 56 (dry chico) is pretty nice. If you brew an American pale ale you are never going to tell it is dry yeast. Everyone that has reported to me loves it. ////////// 3.6 gallons of wort in the mash, 1gallon left behind... 27.7% of extract left behind. Do it again, 27.7% left behind. do it again, 27.7% left behind. We can never reach 100% extraction with a batch sparge (not like we want to). With a continuous sparge the possibility is there to reach 100% extraction. It's done with a mash filter; but the grind has some effect in that case. I've heard of making beer in an enema bag hung on a doorknob. I guess the question comes down to "do you want to?" Return to table of contents
