"Hop addition not too early-malt polyphenols should react" > > Does anyone have the original German edition available? > Perhaps a look at the source would help. I know a little bit of > German (probably just enough to add to the confusion) but perhaps > our collegue Herr Hanghofer from Austria (and any other continental > contributors to the digest) could help us out. I'm so honored and motivated to have the reputation of a "contributor" after a few humble posts in just one year. But sorry - I don't (yet) have the original edition available. I own the standard literature of the other German clan - my son choosed to study only 100 miles away in Weihenstephan, not in Berlin. But I will be trying to get hold of it and I have forwarded the articles to others. The thread is really interesting, but I'm a bit to slow to join - consider I've to read / write in English but have to *think* in German. ~~~~~~~~~~~~~~~~~~~~~ OUTING: ...Yes, I love them all: Porters, Stouts, IPA's... - they add so much contrast to the "usual" Lagers and Wheats that we use to drink and brew here. After having some success with an IPA I'd like to try my hand on Stouts. The difficult part is to get special grains (here in Austria). I'm a poor boy and so I get my base malts directly from the maltster. Importing specialties via HB-shops is no way for me (and no challenge, too). So I need to get some help from the collective: Does anyone have experience with roasting barley at home? Do I need a special barley strain? Hey, I'm specialist in sealing erlenmeyers with burning cotton plugs - so roasting barley won't hurt me ;-) THIA, CHEERS & sehr zum Wohle!

Funny you should feel that way. After posting that, I read over the instructions and made a few changes to get a bit more specific and apologize for sounding harsh. As it was a public "harsh", I am cross-posting this to the HBD as a public apology. Having said that, "Brewing With the EASYMASHER" instructs to heat up the sparge water while the mash is settling. This would provide the needed rest period as it takes at least ten minutes to get two quarts of water boiling on a stove. I should have made a point about the need for the rest. The "Installation Instructions" describe the clearing of a clogged screen by blowing on it. These two "details" could have saved you the hassle. " --Pardon my ignorance of fluid flow and pressure, etc. but what's "head" mean when talking about "given sufficient head." If it's the hose attached to the spigot -- is more than two feet bad? No. The more the better. Head is simply the distance between the top of the water and the bottom of the hose. " Try as I might, I couldn't make the hose to spigot connection airtight (using a 3/8" ID hose, as per the directions). Would that hurt. If air enters the stream, that boogy man HSA can rear it's ugly head. I believe someone has already pointed out the "parting line" on the forging as a potential problem. If it is unduly high, just file it down to make a smooth surface. " That's even with the inside copper tube rotated so the intake is above the outlet of the apigot. When it's rotated down near the bottom of the kettle, I think most impartial observers would characterize the flow as a "trickle." There is obviously something wrong as it should make no difference whatever how the tube in rotated. Unless of course, the kettle is near empty and you are trying to get it started. In that case, if the strainer is below the spigot, you have to consider it as a syphon because it has to lift the water and will not run at all with out suking on it. If it is that empty, you are done anyway. " Here's what I'd like to know --- Is there some sort of test we can do to make sure there's not something wrong with the outlet on my EM? Shouldn't clear water come out faster? You really need to qunatize things. Faster is not very helpful. Fill the kettle and open the spigot and time a gallon. I don't recall the number but more than 5 minutes would surprise me. " Or is this related to the "sufficient head" thing? Most assuridly. If you take your two foot hose and hold the end near the top of the kettle, nothing will flow. It's a poor man's spigot. Put the end of the hose 2 feet below the spigot and you will get max flow. Everything in between is linearly related to the height of the END of the hose. " Second -- what's your response to the advice that I put a ball valve on the outlet? I don't like it because the EM is supposed to work! I would have to suggest that 10,000 users replace our spigot with one that "works", when it fact the one you have (should) works. For what it's worth, I have been making 10 gallon batches with that spigot for about 5 years. My sparge time is about 30 minutes for 12 gallons of wort. I have the same spigot on my sparge water tank and my brew kettle, in addition to the mash tun. Trust me, it works. Send it back and I will cheerfully send you a new one if it does not pass the above test. js - -- Visit our WEB pages: Beer Stuff......... http://ays.net/jsp Astronomy....... http://user.mc.net/arf ASTROPHOTO OF THE WEEK.....

Date: Thu, 12 Feb 1998 15:20:15 -0800 From: Kyle Druey <druey at ibm.net> Subject: Predicting %AA, Ooops >From: "Riedel, Dave" <RiedelD at dfo-mpo.gc.ca> >Subject: Datapoints for the Druey Equation or..? Dave, thanks for trying out my %AA equation when using the 60/70 mash schedule. I hope it didn't ruin your Viena Lager by having it come out a little high on the FG. For those of you who don't remember, this equation will estimate the amount of time needed to rest at 140 F to produce a desired %AA. When I originally posted my equation, I was lectured by a couple of HBD xpurtz that predicting %AA with a one factor equation was not possible. There were many more factors involoved such as yeast strain, fermentation temperature, fermentor geometry, yeast viability, wort oxygen levels at pitching, etc. etc. etc. >For the Dunkel, I wanted to go from 1.053 to 1.014-15; Kyle's linear >model said: 26-28 min at 60C/140F and 62-64 min at 70C/158F. >SG 1.053 >OG 1.014 (2 wks later) - now lagering at ~2C/34F This isn't too bad. The new super improved exponential model estimates a mash time of 29' (such precision :>) at 140 to hit an FG of 1.014. >For the Vienna, I wanted 1.050 to 1.010; Druey's new and improved >exponential said use 60 min at 60C/140F and 30 min at 70C/158F. >SG 1.051 >FG 1.015 (ferment only lasted about 1 week; racked after Ooops, looks like we missed a little. Don't know why. I did notice that you had quite a bit more stewed malt in this batch than the previous one, adding unfermentables to the finished beer. Without doing a residual sugar analysis it is hard to tell whether or not the yeast pooped out. Dave, you now have two data points with your system, I hope you continue to try this method for estimating %AA and collect more data. FWIW, I have done two brews since I published the new exponential model, here are the results: Oatmeal Stout: OG 48, design FG 16, 14' at 140 F, actual FG 17 Bavarian Weissbier: OG 48, design FG 8, 90' at 140 F, actual FG 7 Both brews missed a little, but did pretty darn good at hitting my design FG. I did do a residual sugar test on each beer to confirm the end of fermentation. >Kyle's offering a snake-oil equation? :) YMMV! The only reason I developed the equation is because I had not run across any references on how to predict FG other than Noonan's 1/4 gravity rule of thumb, which to me was not satisfactory for beer design purposes. Another point to add is that the equation is also system/process dependent. Electric element RIMSers may not achieve the same results as direct fire RIMSers, etc. >Writing nearly as much as my namesake Mr. Burley, but resisting the urge >to summarize everything and recommend Clinitest ;^) I have to admit that I blew off the Clinitest claims until Burley suggested I try it. I know this method has been pooh poohed by some HBD xpurtz, but it is easy to use and gives me 'homebrew' level of testing accuracy to confirm the end of fermentation. Andy Walsh had a post where he did some excellent testing on the effectiveness of Clinitest to identify residual sugars in beer. From what I remember, he did not exactly give Clinitest an endorsement. Give it a try for $9 for a 50 tablet test bottle (you need to special order it at your pharmacy). You be the judge. Now I am going to use Clinitest, my hydrometer, and identify when the yeast begins to drop to determine the end of fermentation. Since I use open fermentation, the bubble test is not an option. Thanks to everyone who sent me information on malt modification and protein rests. All the posts and private emails totaled 18 pages in MS Word, and still growing thanks to George DP!

Date: Fri, 13 Feb 1998 02:51:50 -0500 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: Re: protein rests, clove flavor and yeast storage Tidmarsh Major asks about protein rests and chill haze >> 11. "Hop addition not too early-malt polyphenols should react" > >Also, while I'm still not convinced that protein rests are necessary, I >will quibble with George's interpretation of Kunze that all protein rests >are detrimental. I believe that Ludwig Narziss at Weinstephan also eschews the 45C to 55C temp range with modern malts. I think that this was mentioned in a G.Fix thread here some time ago, possibly by Charlie Scandrett. In any case Kunze is not the only source of this idea. As for the malt phenol reactions before hop additions - this idea appears in many sources. There may be some basis for this as the malt polyphenols do not bind as readily to proteins as some of the hops gallate phenols. But then the idea might be to link and later crosslike the malt polyphenols and some proteins and thus leave the polyphenols in the break matter or as sediment. More of an educaed WAG than information. Samuel Mize asks about Weissbier with clove character >Three questions: >Is there anything else I should be doing to encourage this character? The clove flavor is primaily from 4-vinyl guaiacol, which is formed by certain yeasts from ferulic acid. To maximize the 4VG, you should maximize the ferulic acid and then choose a yeast with a good ability to perform the conversion. If you were mashing, then a rest at around 45C(113F) can help to produce extra ferulic enzymatically. Wheat or wheat malt may be a richer source of ferulic than barley or barley malt. If you are extract brewing, then you have no control over the content, except by choice of extract. As for yeasts, in the one study for which I have data, 4 weizen yeasts varied in 4VG production by a factor of 18. I don't have specific yeast recommendations, but someone posted to HBD recently about several non-wyeast strains that the poster felt were stronger 4VG producers than the wyeast varieties. Also fermentation temps around 20C/68F are optimal for 4VG production. >Does serving temperature significantly affect perception of this? Yes, IMO the clove flavor drops off at too low temperatures, tho' not radically. Also the ester aromas which are common in good weizens become relatively more prominant at higher temps. >What commercial wheat beers have this character? My Michael Jackson book [...] Fresh weizens. The 4VG decays into relatively flavorless comopunds in a matter of months. The half-life for 4VG in beer is about 60 days at 18C, 27 days at 37C. If Tucher Weizen had no clove flavor, find another retailer with fresher stock, not another beer. Troy Hager asks about Long term yeast storage in distilled H2O >Are other people doing this? I've tried this several times with lager yeasts in the past year. So far I'm not very impressed with the outcome. The yeast strain can be resusitated without a problem - so it is a successful technique. My concern is that I must step-up this culture repeatedly to get a heathy sized yeast crop. Most of the yeast seem to die during storage. I should mention that I wash or separate the yeast using water before storage. I have since read that this cleaning should be reserved until just before you wish revive the yeast. Steve Alexander Return to table of contents

Date: Fri, 13 Feb 1998 07:57:32 -0500 From: Dave Whitman <dwhitman at rohmhaas.com> Subject: Distilled H20 yeast storage In recent HBDs there has been interest in sterile water yeast storage. I've been maintaining 6 yeast cultures this way for about 2 1/2 years now, reculturing every 6 months. Seems to work very well, and my (admittedly untrained) palate can't detect differences in taste/quality of the beer I get using the stored yeasts. During the past 2.5 years, I've had to replace one culture that just didn't wake up the next time I went to use it (Wyeast Irish Ale). Don't know what went wrong; I've got a fresh sample of that yeast which seems to be storing well. I did a write up of the procedure which is archived at the Brewery web site: http://hbd.org/brewery/library/SterileDW1096.html Dave Whitman dwhitman at rohmhaas.com "Opinions expressed are those of the author, and not Rohm and Haas Company" Return to table of contents

I've never brewed with floor malted barley, but i've gotten samples of and I can tell you that the difference in appearence is night and day. The floor malted stuff is *much* nicer looking malt. fat, plump, real good tasting... but like I say, I don't know if the performace is different.

This struck me when I purchased the book as an extraordinary omission. How can you not mention the country which produces the finest beers in the world?

Date: Fri, 13 Feb 1998 10:42:57 -0500 From: Andrew Stavrolakis <andrew_stavrolakis at harvard.edu> Subject: yeast for big beers Ken Schwartz reports on nottingham dry yeast performance in big beers: OG = 1.092 FG = 1.017 noting it's 82% apparent attenuation, and goes on to attribute it to his "total ineptitude in acheiving a respectable mash temperature; I hovered right around 150F which resulted in a very fermentable wort." Don't be so hard on yourself, Ken! I've noted the following results using nottingham dry: Beer Pitch Rate Sacc Temp OG FG AA 1 1 pkt/gallon 150F 1.079 1.012 85% 2 1 pkt/gallon 160 1.102 1.020 80% 3 1 pkt/2.5 gal 158 1.062 1.010 84% 4 1 pkt/gal 150 1.085 1.014 84% 5 1 pkt/1.5 gal 155 1.057 1.010 82% 6 1 pkt/1.5 gal 152 1.062 1.010 84% 1 packet=7 grams, I believe. This yeast seems very highly attenuative, regardless of mash temp. It's also a flocculant but vigorous nay, even violent, fermenter, all while maintaining a very neutral flavor profile. As you can see, I've pitched at very high rates, and I think this is a key to successfully fermenting heavy beers (or any beer for that matter). None of these had any trouble conditioning in the bottle. This yeast in my experience has been very consistent in its performance, and I find myself using it more and more. Dry yeast has the advantage of allowing you to easily pitch adequate amounts to successfully ferment heavy beers. Yes, I do use liquid yeast, but more and more only for my lagers.

This is the infamous "=" characters throughout certain peoples posts. I've discovered that it is not always their mailer doing it, but rather the mail transfer agent converting the email to quoted-printable. I've been searching for a filter that I could just snag and put in place, but every single one of them had certain limitations, plus other non-desirable aspects. So, I wrote one. It is RFC compliant if anyone cares, except in one aspect: only ASCII characters will be interpreted. Any character that is quoted that has a decimal character value greater than 127 is thrown out. Sorry, but we must maintain ASCII services only. Later, I will be adding additional features to the filter, like properly parsing and dealing with multi-part mime messages and possibly other Content-transfer-encoding issues. But for now, Dave Burley's and other folks will see their posts in a different light. Back to beer talk... ============================================================================ Karl F.

Date: 13 Feb 1998 13:37:29 -0500 From: EFOUCH at steelcase.com Subject: Wyeast 3942 HBD- I haven't been able to find any information on Wyeast 3942, Belgian Wheat. What are the characteristics of this yeast? Does it like to use ferulic acid? Should it be treated like German wheat yeasts, or is it not really a clove or estery developing yeast strain? Another question about Wyeast- When I first started brewing using dry yeasts, I heard about these liquid yeasts from a company called Wyeast. When I read the name to myself, and spoke of it to others, I found myself automatically calling it "Y-yeast". To this day in conversations with people I hear them call it "Y-yeast", even though it's spelled Wyeast. Granted, "Wyeast" is harder to say than "Y-yeast". How wide spread is this? Is this a Midwestern idiomatic speech deficiency, like saying "Youse guys"? How do the people from Wyeast pronounce Wyeast? That wasn't too "scathing" was it?

It is make by a company called Magic American Corporation. It says on the bottle "Biodegradable 100% Organic Citrus Based". The trick is to remove the label under hot water so that you get all of the label off with just some residual adhesive left.

Date: Fri, 13 Feb 1998 14:12:57 EST From: AlannnnT at aol.com Subject: Brewing Techniques mag Doug Moyer wrote about how much he liked Brewing Techniques Magazine. Doug, I just ordered some back issues from them, and boy was I pleased. And if you order back issues BT doesn't slaughter you with prices like Zymurgy [from the AHA]. In one of the issues [from 1995] is a device similar [better?] to the MIXMASHER tm thread from last month. I wonder how many articles are in BT because of the HBD, and the exchange of ideas on the forum. Chicken or egg thread to follow. Interesting to note that BYO has many more times the subscription base then BT. Which mimics the discusion we [the HBD} had last year about 'who' the average brewer is. The average brewer reads BYO not BT. It's too bad, the average brewer may not be having as much fun as we are.

Any pointers to archives dealing with perfecting Extract beer would be appreciated.>> David, Having brewed nothing but extract for five years, I think I can give some advice. However, much of what's helped me brew better extract comes from applying all grain wisdom, gleaned from the Homebrew Digest, to my extract brewing. As you also brew all grain you have capabilities that many extract brewers may not have, specifically, a wort chiller and the ability to do a full boil. That' important. There'll be a Part 2 to this reply which will cover tips for those who can't do a full boil and don't have a wort chiller. Ingredients: Unless you're looking for an extract from a particular type grain or with a particular chemistry, I've found generic works just fine. If you're going for light color, I strongly recommend LD Carlson Extra Light DME. I've found DME generally produces lighter colored beers, while LME seems to produce a clearer beer. I don't recommend corn sugar except to bottle. If you want to lighten the body or boost alcohol w/o increasing the body or maltiness, use honey or rice syrup/rice solids. Specialty grains. I've tried "steeping" by holding at 165 F. I've also used the much maligned Charlie Papazian method of starting the grains in cold water, bringing the water to a boil, and removing the grains just as the water begins to boil. Both have worked well and the latter is more convenient. Hops and yeast. Same as if you're doing all grain. Procedures: Minimum of 60 minute boil is best. Produces a better hot break, cold break, and final clarity. Just as you begin your all grain full boil with a greater volume than you want at the end, do the same w/ extract. Chill as quickly as possible, and before sparging. After that, it's no different from all-grain. Regarding recipes. I've used the recipes in Papazian's TNCJOHB extensively. Have used them as is and also modified them. Any other all extract all seem to be variations of those in the book. The following is something I concocted for my wife who prefers lighter, less hoppy beers: Kim's Ale This recipe is for SIX gallons: 4.2 lb. LD Carlson, Extra-Light DME 3 lb. light clover honey 1 oz Hallertauer Hersbruck hop pellets (bittering) 1/2 ozMount Hood Hop pellets (finishing) Wyeast 1007 German Ale liquid yeast Bring water to boil. Add DME and honey. Return to boil. After 15 minutes add bittering hops. Boil another 45 minutes (one hour total boil time), adding finishing hops for the last three minutes. This recipe would also work well with Wyeast 1056, American Ale, liquid yeast. If you are able to lager, use either 2007, Pilsen, or 2272, North American (finishes beautifully clear.) This is a recipe for a nice light bodied ale or lager (five gallons): 1 can (3.3 lb.?) Alexander's Pale LME 2 lb. LD Carlson Extra-Light DME 1/2 lb. rice solids 3/4 oz. Cascade hop pellets (bittering) 1/2 oz. Cascade hops (flavor) Wyeast 1056, American Ale liquid yeast for an ale Wyeast 2007, Pilsen, or 2272, North American for a lager Bring water to boil. Add DME, LME, and rice solids. Return to boil. After 15 minutes add bittering hops. Boil another 35 minutes. Add the flavor hops and boil another ten minutes (one hour total boil time). Chill, sparge. Pitch yeast. Hope this helps. Feel free to E-me if you think I might be able to help. Charles Return to table of contents

Any pointers to archives dealing with perfecting Extract beer would be appreciated.>> Many extract brewers can't do a full boil and don't have a wort chiller. Here's what I recommend for a work-around. Use a five gallon pot, minimum. Start with 2 1/2 -3 gallons of water, bring to a boil, (remove the specialty grains if you're using them) and add the extract, honey, rice syrup, etc. This should put the initial volume at 3 1/2 to 4 gallons. Do a minimum of one hour boil. This is high adventure as 4 gallons of wort boiling in a 5 gallon pot can boil over easily. Boil uncovered. Volume at the end of the boil will be around 3 gallons. If you have a wort chiller, use it. If not, do not sparge the wort while it's hot. Add about a gallon's worth of ice to the wort, cover the pot and put it in a sink or tub of cold water, or, even better, in a snow bank. After about 30 minutes it will be safe to sparge, through a strainer, but NOT yet into the fermenter. Sparge into a bottling bucket (the kind w/ the outlet for the valve about a half inch off the bottom) and add chilled water to bring up to the desired final volume of the wort. Cover loosely. Over the next hour the wort will cool some more and trub will settle out. Unless you've used a lot of specialty grains, all the trub that's going to settle out at this point will have done so w/in an hour. Under no circumstances let it sit for more than three hours. Sparge into the fermenter and pitch the yeast. Return to table of contents

Comercial copper has a small percentage of copper oxide in it. When heated at welding temperatures this leads to oxide embrittlement. I recommend that you should use deoxidized or oxygen free copper for your trial, this is also true with welding or brazing rod. I would recommend either GTAW or GMAW welding for the splice. This is also the recommended standard for this type of welding. GMAW = Gas Metal Arc Welding GTAW = Gas Tungsten Arc Welding You could also braze with filler metals such as BAg, BCuP or RBCuZn-A. What these would do to your wort or to your brain I do not know. Dustin Return to table of contents
