Date: Thu, 25 Mar 93 9:49:58 EST From: Jim Busch <busch at daacdev1.stx.com> Subject: RE: Petes Wicked Clone In the last digest, Tom posted a fine recipe for a strong brown ale: 8# domestic 2-row 1# CaraMunich 1# CaraVienne 1# dark German 8 oz CaraPils 6 oz chocolate Mash-in 4 gallons at 57 C (135F) strike heat. Falls to 52C (126F). Protein rest 30 minutes. Raise to 68C (154F), Saccrification 2 hours. No mashout due to brain-cloud. You probably should Sparge with 6 gallons at 75C (167F) Got 7-1/2 ~ 7-3/4 gallons. Gravity is 1046. Extraction = 29.7 points/#/gallon. Boil 90 minutes. 4.4 aau Fuggles for 60 minutes, 4.4 aau Fuggles for 30 minutes, 5.2 aau Kent Goldings for 2 minutes. Chill to 25C (75F). OG = 1060. Pitch Wyeast 1098 FG = 1.018 A question: What is Dark German?? Comments: While I think this is a fine recipe, for a Petes Clone, try all Cascade for the hopping. I would also tone down the OG into the 1.052 - 1.055 range (as TOm indicated by suggesting less pale malt). One can also try the Worlds Greatest Yeast (tm): Wyeast 1056/Narragansett/Dominion Ale. You can also make a fine example of this beer with a single step infusion. In fact, the body may go up in the final product when a single step is used due to the rapid conversion of domestic pale malt between 130 and 150F. Tom certainly has plenty of body in his 1.060/1.018 beer, but if you try the Worlds Greatest Yeast (tm), the FG will approach 1.010- 1.012. By dropping both OG and FG, you will end up with roughly the same alcohol by volume. Good brewing, Jim Busch PS: Brooklyn Brown Ale is a "Petes Wicked" clone, brewed by FX MAtt, and when fresh , quite delicous. Return to table of contents
Date: Thu, 25 Mar 93 10:02:57 EST From: Ulick Stafford <ulick at bernini.helios.nd.edu> Subject: Diacetyl, etc. My most recent lager, that was supposed to be a vienna, but is an Helles, seems to have quite noticable levels of diacetyl. While, this flavor is quite pleasent, and overall the brew has a beautiful malty palate, all that I have read seems to be very concerned about diacetyl levels because they indicate a yeast gone bad. Should I dump all yeasts from that strain and use a fresh lager strain? AHA guidelines seem to indicate that low diacetyl is OK for most lagers. My brew procedure used a 2 week primary at 50F followed by lagering for 4 weeks, the last 2 at 32F, and was bottled with Krausen. The Krausen worked beautifully. I have the most\ beautiful carbonation, and it came quickly. This is with very low sediment levels, but I guess I was fortunate to have brewed a Helles the previous day! Other points. I just read Eric Warner's Weissbier book. A good book. Well worth the $9.50 Classic Beer style books cost at the local store. Some points of interest. He is very unconcerned with oxygen introduction at bottleing because the yeast will use it. This contradcits other writers wh tend to be anal on this point. Suggests priming with Speise (literally food) and suggests the first runnings, from the lauter tun (with pasteurization). Anyone tried this? He is, unfortunately, unable to answer the 6 million dollar question - an affordable source of the proper yeast. __________________________________________________________________________ 'Heineken!?! ...

Date: Thu, 25 Mar 93 9:30:07 CST From: tony at spss.com (Tony Babinec) Subject: canned Guinness/what's a good beer? Phil Hultin says that Draught Guinness did not fare too well in a blind tasting. Assuming that the Draught Guinness was in good condition -- and this I don't know -- I'll speculate that what we have here is an example of tasters scoring high the beers they like. To the best of my knowledge, canned Draught Guinness has OG 1.040 - 1.046, which makes it smaller in gravity than the bottled Guinness Extra Stout, OG 1.052 or so. Guinness, being an Irish Stout, is quite sharp and dry, with roasted barley being the signature dark grain. Guinness is therefore dry and not to everyone's taste. And, at its gravity, Draught Guinness doesn't have a lot of body. In my opinion, when a beer is judged, the major questions ought to be: - is it clean with no obvious faults? - is it brewed to style? - beyond the above, does it delight you? In fact, in AHA/HBWTA events, judges use detailed point systems. Some score from the bottom up -- x points for malt, y points for hop, z points for appearance -- while others develop a quick overall assessment of the beer, and then use the scoring sheet to aid them in pinpointing the attributes of the beer. If the beer has no obvious faults -- for example, obvious bacterial contamination or a stale, oxidized flavor -- and is brewed to style, then it is a good beer. You may not like it, but it is a good beer. For example, some people don't like the clove-like phenol flavor found in some weizens. If, in addition, the beer delights you, then that might nudge its score higher. If it doesn't delight you, that doesn't make it a bad beer. The unfortunate reality is that some judges give far too much weight to subjective factors and matters of taste. Probably among the worst things done is to wrongly label a beer as infected. This can happen with spiced beers or belgian beers. Also, it is not uncommon amongst homebrew aficianados to see the hoppiest beer or the biggest-gravity beer be the most preferred. Of course, this taste and preference would not occur amongst the Lite-beer-swilling crowd. An example of big beers winning is the AHA stout style. Take a look at past issues of Zymurgy. Every year at AHA national, the winner in the stout category is an imperial stout. While the winners were undoubtedly good beers, why hasn't a conventional gravity dry stout ever won? Do better brewers make big beers? Are novice brewers more likely to submit conventional gravity beers? Whatever else is going on, I submit that many homebrewers and homebrew judges are like the musician in Spinal Tap who pointed out that while most guitar amplifiers range from 1 - 10, his went up to 11. In other words, we like our beers with all the dials set on high. To be a better judge, one should constantly improve knowledge and skills regarding ingredients, process, flavors and faults, styles, national traditions, and commercial examples. For all brewers and beer enthusiasts, let's recognize that beer has an astounding range of styles and flavor profiles. It is surely much more varied in flavor than the range of wines is, for example. So, instead of abolishing all styles except for BarleyWine, Imperial Stout, and Eisbocks, let's leave some room for the session beers too! Return to table of contents

Date: Thu, 25 Mar 93 9:38:09 CST From: tony at spss.com (Tony Babinec) Subject: us versus belgian carapils Just a reminder: U.S. CaraPils and Belgian Carapils are not the same thing. U.S. Cara-pils is dextrine malt. As described in Jeff Frane's excerpts, it is hard and glassy, has minimal color, and is used to add body. It contributes dextrines to the beer, which won't be fermented by beer yeast, and therefore will remain in the beer. Belgian Cara-pils is a light caramel malt/crystal malt, with a color rating of 8L. It can be used in recipes calling for "light crystal malt." It will contribute some color and some caramel sweetness. Return to table of contents

Date: 25 Mar 1993 10:02:25 -0500 (CDT) From: ATKINSON at vaxb.acs.unt.edu Subject: Re: Brass Fittings - Composition Russ Gelinas asks about the compostion of brass, and any concerns about lead. According to "The Condensed Chemical Dictionary, 9th ed." Brass is a copper-zinc alloy of varying composition, typically with zinc content ranging from 15% (highly corrosion resistant brass) to 40% (called Muntz metal; used for hot working alloy when cold-forming operations are unnecessary). "Some brasses also contain low percentages of other elements, e.g. manganese, aluminum, silicon, lead and tin)." The Dictionary indicates that the only hazard of brass is the it is "flammable in powder or finely divided form". The Dictionary does indicate that additional information can be obtained from the Copper and Brass Fabricators Council, 225 Park Avenue, New York (how's that for an address!). It turns out that children are much more susceptible to lead poisoning than adults. Children may begin to experience symptoms when the level of lead in their blood reaches 40 micrograms per 100 grams of whole blood; the threshold for adults is about 60% to 70% higher. EPA's drinking water standard is 0.05 milligrams per liter. This level was derived assuming that one drinking 4 liters of water per day over an average lifetime with levels of lead lower than the standard will prevent blood level concentrations from reaching levels where symptoms will occur. We are also exposed to lead in trace amounts in the food that we eat; it is naturally occurring in soil; it is in many pesticides, and it is attached to airborne particles (this is why EPA has banned leaded gasoline). One estimate is that we ingest approximately 130 milligrams of lead each day in our food and drink (ReVelle and ReVelle, 1984 - "The Environment: Issues and Choices for Society"). IMHO, the amount of lead that may be leached out of the few brass fittings the we may use in our brewing gadgets, even under the lower pH levels that brewing creates, would add only a very small increase in the lead we are exposed to. In addition, for every hour we spend brewing, we are reducing the risks of walking across the street and getting hit by a car! So, I think you can add as many brass fittings as you want to your system (stainless steel would be better, but its about 10 times more expensive), not worry, relax, and you know....

Well certainly canned Guinness does a bit better but, >hey, it tastes watery to me. I'll stick with the bottled version. The bottled Guinness Extra Stout commonly available here in the US is considered by many to be a world class beer (including myself,) but this is a completely different product from Draught Guinness (canned or otherwise.) It's sort of an apples to oranges kind of thing. The Guinness Extra Stout is a higher OG product, with a correspondingly higher hopping rate. The draught versions(s) are intended to be much lighter (to use a bad term) and I think more "quaffable". Whereas I don't have any problem drinking multiple pints of Draght Guinness, usually from a real tap at one of several Boulder pubs, I know I would have great difficulty consuming more than a couple of bottles of the Extra Stout in a single sitting.

Yes, this is without adding the milk. If you added a pound of rolled oats to your mash, you would be adding the equivalent of 32 g, just over an ounce, of lipids. Given that there must be some lipids in barley, and that some folks add baking chocolate (50 to 70% fat) to their specialty brews without complaining of head retention problems, could roughly an ounce of oat lipids be responsible for the beheading of a stout? Sometimes an oil film on the serving glass can mess up a beer head. Check (with) your dishwasher too. Cheers -- Jean (Sigbars waste bandwidth) Return to table of contents

After about 5 years of boiling specialty grains, and ending up with beer that tasted much better after a year in the bottle, I stopped boiling my grains and voila! beer that tasted good out of the secondary. As I understand it, higher temperatures will leach tannins out of the husks of the grain. These tannins will add an astringent taste to you finished product. The yeast in each bottle will *eventually* reabsorb the tannins, but it is better to avoid them from the start. The only doubt I have with your described method is that you don't boil the resulting liquid from the steeping of the grains. Once you have removed the husk material, it is safe to boil the resulting liquid, and may even be beneficial. A boil could kill off residual nasties, although I don't know if anything could live in 170F water for an extended period of time. Boiling might also alter the sugars in the solution. On the bottom line, if it tastes good, you *must* have done the right thing. Andrew Lynch, Kubota Pacific Computer, Santa Clara, Ca. atl at kpc.com Return to table of contents

Fermentation Frenzy in Los Altos, Ca. has slants of Duvel yeast that I have used to attempt Duvel clones. I'm pretty sure that these cultures would be better to use than the yeast in some poor abused bottle that's been on the shelf forever. I don't know the technical profile, but it smells and has aftertaste like Duvel. I have done one extract and one all grain attempt at Duvel. The all grain came much closer, as I could control the percentage fermentable vs. percentage unfermentable sugars in the wort. Normal (tm) extract will have a ratio balanced towards normal beer, and Duvel is not normal. It is quite difficult to get the high alcohol content without excessive body and residual sweetness. My all grain batch included 18lbs of grain and 3 lbs of honey for a 5 gallon batch. I mashed for several hours at 148F to try to get maximum fermentable sugars. The Duvel yeast fermented it from about ~1.090 to ~1.025 in just over one day! Another week brought it down to about 1.015. Truely impressive. It ended up with the nice blond color and rocky head of Duvel, but was still a little too sweet. Duvel in Belgium hasd 9.5% alcohol (not sure if by weight or volume) and the US version has 5.2%. If there is interest, I will post the recipe, but I don't want people to think I really got it just right.

The concentration of alcohol changes the taste (or how one perceives the taste) of the final product. Can't argue with the facts but if one uses a low tolerence yeast, you can minimize the problem. >From: R_GELINAS at UNHH.UNH.EDU (Russ Gelinas) > First, I read in a health newsletter than *brass* fittings, ie. a brass spigot, especially when new, can leach lead into water. What is brass? Copper and ???. Sounds like a case of the media over-reacting to something they know nothing about. Brass is an alloy of copper and zinc. The amount of either that can leach into beer is probably not measureable and both, in small doses are necessary to human health. js Return to table of contents
Date: Thu, 25 Mar 93 14:47:46 EST From: dipalma at banshee.sw.stratus.com (James Dipalma) Subject: bad supplier alert Hi All, Just curious, anyone else having problems getting orders filled correctly by Northeast Brewers Supply in RI? I have been (or was) a customer of thiers for about one year. Over the first few months that I did business with them, several orders were shipped either incomplete or with the wrong items. On most of those occasions, the problem was that they did not have the item in stock and had it on backorder. The irritating thing was that they would not tell me this when I placed the order, even though the information was on their computer. I would not discover that the order was incomplete until I received it, one or two days before brewday. Each time this occurred, it put me in the position of scrambling around at the last minute trying to second source the items from other vendors. After several such incidents, I called and spoke to the owner, a Mr. Kerry Brown. He told me they had just put in a new computer system and hired a lot of new help, and to please bear with them. Being the understanding, easy-going fellow that I am, I was satisfied with that explanation. Things got a little better for a while, as only the occasional order was screwed up. Two weeks ago, I ordered one pound of Saaz pellets, and 1/4 pound of several other types of hop. After waiting eight days, I called to find out what had happened to my order. After being left on hold for 15 minutes, the person at the store said he was alone, the phones were ringing and the place was full of customers, so he did not have time to look for the shipping log. He could'nt say whether or not the order had been shipped. He did locate my order, but it was totally wrong, they had it as 1 *pound* of each hop. The next day, as a result of my complaining, I received a phone call from Mr. Brown, ostensibly because he "was interested in my feedback as a customer". I explained the problem with the hop order, and amazingly, he went into the same speil, new computers, new help, blah blah blah. I reminded him that we had held exactly the same conversation 8 months ago. He then tried a new tack, that "it's hard for any computer to track $10K a day in inventory". Gee, it's funny how in this age of online transaction processing, banks can transfer millions of dollars a day across vast distances with no problem, but NE Brewer's computers can't track a few ounces of hops in the backroom. Then it was "banks spend a lot more money for their computers". This is surely earth shattering news to those who use PC driven databases in thier businesses. It became evident that he was interested in neither my feedback or in retaining me as a customer, so the conversation terminated. In all fairness, NE Brewers does offer very low prices. However, in my opinion, this is made possible because they hire the cheapest, least qualified help they can find, and then understaff, as evidenced by the lone hapless clerk trying to wait on customers and answer the phone concurrently. The bottom line is, you *can* get good prices from NE Brewer, but you had better have a second source lined up, you may very well need it. Jim Return to table of contents

Date: Thu, 25 Mar 93 15:05:40 cdt From: "Knight,Jonathan G" <KNIGHTJ at AC.GRIN.EDU> Subject: off-flavor puzzle Here's one for all you beer - sleuths. I have been re-using yeast by saving the slurry from the primary and washing it using the sterile-water method. Recently, I decided to pitch a new batch directly onto the yeast cake in the SECONDARY of a previous batch. Both of these batches have developed a similar off-flavor. I would described this flavor possibly as either "wet cardboard" or "cooked corn" - but since I can't decide which, perhaps it is neither and I'm just groping for terms to describe it from stuff I've read. And incidentally, I don't remember where I read them or what is supposed to cause these particular flavors. Quite a few batches ago I had one that turned out "cidery," and there was absolutely no doubt about how to describe that. The cideriness subsided after a few weeks in the bottle and the beer was not great, but drinkable. But I digress. The interesting thing is that a third batch of beer made from the same yeast, washed from primary slurry, shows no sign of that flavor defect. The three recipes are completely different except for the yeast. Personally, I suspect that my problem came from reusing yeast from the secondary that had been DRY-HOPPED. Here's the scenario: Batch one, California Common using Wyeast "California," from package built up in DME starter. Batch two, a porter (?) or at anyrate a dark steam beer, made with California yeast saved from prinary of batch one. Bathc three, a cream ale (or cream steam in this case I suppose) made with California yeast from secondary of batch one (which had been dry-hopped). Batch one and batch three have identical flavor defects. Batch two is fine. And here are my questions: (1) Could the flavor defect in batch one be due to leaving the hops (pellets) in the secondary too long? I thought moving the beer off the slurry in the primary would take avoid the risk of developing off-flavors in case of extended stay in the fermenter, but perhaps the dry-hopping has its own risk in this regard. (2) Should I suspect infection? The hops I used for dry-hopping smell fine in their package, although I doubt I could pick up anything by nose that way. Perhaps the infection was introduced when transferring batch one to secondary, and from there to batch three. (3) What are the chances of bottle conditioning taking care of this? I should add that the flavor problem is not overwhelming - it sticks out like a sore thumb to me, but my wife guzzles happily and doesn't know what I'm talking about. Any thoughts would be greatly appreciated! Jonathan Knight Grinnell, Iowa Return to table of contents

Date: Thu, 25 Mar 93 19:25:17 PST From: jwsb at netcom.com (Justin Broughton) Subject: Extract Rates, Flavor and Color I am curious about a subject I have not seen mentioned in any of the books I have read. This is, what is the relationship between extract rate, flavor and color. What happens if I am using a recipe which has an assumed stellar extract rate, and I know my equipment can only get a percentage of it. If I up the grain amount, will I get a more flavorful/colorful brew. Also vice-versa if I am using a recipe which assumes very low extract rates will my brew turn out tasteless and colorless if I tone it down to meet my extract rates?

Date: Thu, 25 Mar 93 22:59 CST From: akcs.chrisc at vpnet.chi.il.us (chris campanelli) Subject: That was gonna be my second guess The other day I was subjected to a blind tasting at a friends. "Try this", he said, "It has some flavors that I can't quite place". "What style is it?", I asked. "It has some problems but the style should be pretty evident." he said. So I put on a judge's air and proceeded to dissect the beverage according to the latest AHA guidelines. Appearance: Very pale, Miller Lite-ish in color. Way over- carbonated. No head retention. Nose: Perfumy. Fruity, apple-like. No malt nose. No hop nose. Flavor: Starts out fruity. Finishes dry with some tartness. No body, very thin. Gassy. After surreptitious evaluation, I decided that it must have been a very bad mead/cyser or an OK sparkling cider. But which? Depending on what I said I could have bruised an ego or given tribute unto Caesar. I loathe those situations. It required tact. Ann Landers, where are you when I need you. Summoning all of my self-taught guile, I responded: "Well, it certainly is interesting." "You don't like it?" he asked. "Um, no, it's not that I don't like it, it's just that it could fall into a number of different categories and I'm having a little trouble deciding which. On one hand it tastes like a very good cider but on the other hand it tastes like a mead or cyser that needs a little more aging." I said as I mentally patted myself on the back. "Well, truth be told", he said, "it's a French champagne. Perrier-Jouet to be exact, vintage 1983." (silence) While trying not to blush too brightly I confidently responded, "I knew that". chris campanelli Return to table of contents
