Saaz in the UK are more expensive than other hops and are regarded as giving good aroma and flavour so I wouldn't spend the extra if I was simply bittering. If they aren't more expensive where you are then that's differnet but it still seems a shame to do it. You mention a figure of 4.6% AAU, my book says 5.5% (maybe different units) but that is still not very high. There are many others including "high-bittering" hops with percentages of 9%-12%. Hops are generally categorised as aroma, general purpose, bittering or high-bittering. Saaz is considered as an aroma hop. I normally "bitter" with general purpose hops but for a high bitterness would use bittering or high-bittering hops for economy and convenience. Cheers, Brian Return to table of contents

I've spoken to a couple of homebrewers who took the Anchor tour, and they both said the same thing, Northern Brewer for bittering, Hersbrucker Hallertau for the late additions.

BUT because they're so distinctive, and because Anchor Steam so >obviously doesn't have any of that distinctive character, Cascades produce a strong citrusy, grapefruit-like flavor and aroma, which I don't pick up in Anchor steam. The aroma of Anchor steam is quite floral, seems to me to be very much like Hallertau. That's what I use for flavor and aroma additions when I brew steam beer. Anyone have inside info on this?

Date: Tue, 2 Aug 1994 09:54:58 -0400 (EDT) From: BUKOFSKY <sjb8052 at minerva.cis.yale.edu> Subject: Carboy airspace I've got a batch of mead that has been aging in the carboy for a few months after fermentation was finished. It's been racked several times, so I doubt that there is any more CO2 headspace on top of the mead. The mead is several inches below the carboy neck, and I was wondering if I should be concerned about oxidation. I was planning to let the mead sit for another few months (I'm lazy), but will I be in trouble? Thanks, Scott No cute comment. Return to table of contents

Stevens <stevens at stsci.edu> Subject: Re: 5 liter mini-keg questions In HBD 1490, John Williams <jwilliams at hartford.edu> asked about a deal for buying 5 liter mini-kegs for $55 for 4 with plastic tapper & CO2 cartridge. This is the Datagraf tapper, right? I understand that these are okay for short time periods, but that you can't rely on it to hold pressure in the keg for longer periods, i.e., more than a day or two. There is, however, a solid metal version that is considerably more expensive (I believe about $55 just for the tapper) that, according to Gene Thomas, owner of the Brew Pot in Bowie MD, is more reliable and can hold pressure longer. (Better do SOMETHING for the higher price...thought it DOES look pretty ;-) I've seen the plastic tappers sold by themselves for about $16. What I'd do is buy that, and then go to my friendly local beer outlet and buy 5 litre kegs full of beer and then use the empties. Local stores in my area are selling various brands, such as Warsteiner, DAB, Grolsch etc. for anywhere from $11 to $15 per keg. 4 filled kegs will therefore run you about $50-60, plus the $16 cost of the tapper, and hey, for a little more $$ you get LOTS of good beer to drink as a bonus! Why buy empties? Cheers! - ---Mark Stevens stevens at stsci.edu Return to table of contents
Date: Tue, 2 Aug 94 09:07:14 CDT From: wood at ranger.rtsg.mot.com (Dan Wood) Subject: What kind of infection? [Swallowing my pride and clearing my throat] My name is Dan Wood and I've made infected homebrew. My fellow FVHAA homebrewers and I have suffered from identical infections on all too many occasions. While we have unaffectionately dubbed this malady "the funk", I'm hoping that someone can identify it, based on the clues below. Knowing our enemy would certainly help morale, and could assist in eliminating the problem. The facts: 1. I'd guesstimate that between us, about 2-4 batches per hundred are affected to varying degrees. Way too much brew is being used as drain cleaner. 2. The infections mostly occur in brews made in late spring and summer. 3. We do full boils, good sanitation, etc. Most of us brew in our basements. 4. It smells of rotting vegetables (definitely not HSA), and has a slightly sour taste. The smell is much worse then the taste. 5. The degree of infection grows exponentially with longer lag times. 6. The infection has been present in both hazy and clear beers. It does not create gushers. There are no visible indications of infection. 7. It seems independent of the yeast: whether dry yeast (usually Yeastlabs Whitbread) or generous Wyeast starters were used. 8. It has happened regardless of whether the siphon was started by mouth-to-straw or prefilling the hose with water. 9. It is evident in the primary carboy, not caused by racking, kegging, or bottling. 10. It has been carried from one batch to another where yeast from the secondary was reused. This happened once, I've stopped reusing yeast. I managed to avoid it on my last batch (fingers crossed) through use of extreme sanitation procedures: 1+ hour bleach-water soaks, rinsing in preboiled water, misting all surfaces with vodka, etc. The option of not brewing in spring/summer is very painful to me. Many, many thanks in advance for any information and advice. Dan Wood humble(d) brewer, FVHAA wood at cig.mot.com Return to table of contents
Date: Tue, 2 Aug 1994 10:19:59 -0400 From: djt2 at po.cwru.edu Subject: Re: 5 liter mini kegs A couple of folks have asked about the 5 l mini kegs. My experience with these has been mixed, and mosly poor. I have had three problems. 1) the tap doesn't seal well, unless pressed closed by thumb, not easy with a glass of brew in hand 2) The CO2 cartridge leaks; I must use a new cartridge if kept more than a day or so. 3) It is extremely easy to overcarbonate the cans. I bulged out 4 cans over the last few months, though have had no disasters. This is certainly avoidable if you use a low (very low) amount of priming sugar, but once I bulged a can when the yeast was simply slowly attenuative (it bulged only after 6 months storage). Notably, overcarbonated kegs are *very* difficult to dispense. Overall, these cans are an alternative to a kegging system, but not a perfect one. I recently bought a real keg system; I guess I've ruined any chance of selling off my mini-keg system to HBD'ers by the above discourse. dennis Return to table of contents

I say _some_ success, because it appears the cans may not withstand reuse--after cycling through the four cans, I had a can "deform" on the first reuse. They're a nice idea, but don't necessarily work so well in reality.). You say that the priming recommendation is 1/4 cup for 5l-canning and 3/4 cup for bottling? My instructions said to use about _half_ as much for the 5l cans as for bottling. I wouldn't worry much about bottling and canning from the same batch. I'd never want to put an entire batch in the cans anyway--the cans aren't always very portable for some purposes, it's certainly not a standard competition size, and it's not very good for stashing away a sixpack or two for deferred consumption. When I first used one, I decided to go with an in-between figure for priming and it worked just fine. But one reason it works for me is that I would never consider using 3/4 cup per 5 gallon batch. I don't know where that amount ever came from, but I consider it WAY too much. If I want a HIGHLY carbonated brew I might use 1/2 cup. Typically, however, I use 1/3 cup or less for bottling a 5 gallon batch (or the 4.5 gallons or so that remain after racking) and the carbonation and head are just fine. With that amount of priming sugar, thre's no problem diverting 5l to a can. Remember, your instructions were for 1/4 cup anyway. That it might end up a little more carbonated than the bottled product is of some benefit because it will be that much longer before you will have to use a CO2 cartridge to dispense the beer. BUT WHILE WE'RE ON THE SUBJECT, let me throw out the question. Does anyone actually prime with 3/4 cup for 5 gallons?? Bob Paolino Transplanted in Badgerspace Return to table of contents

F8--and didn't finish the question about whether people actually use 3/4 cup) Does that recommendation assume (as might have been the case in the early days of legal homebrewing) that beginners would brew at home to save money on swill rather than to brew nonswill styles, and the massive amounts of priming sugar were needed for the more highly carbonated swillish styles??? Or do lagers (which I don't brew for lack of low temperature control) require more because the yeast is less active over the long lagering periods and cooler temperatures?? Any other ideas why??

Bob Paolino Transplanted in Badgerspace *** Forwarding note from PAOLIRA --WILISVM1 07/29/94 10:35 *** To: I1002526--IBMMAIL From: Bob Paolino Research Analyst Subject: Vancouver pubs? Let me add my two cents on the Seattle/Vancouver question: First, if anyone DOES know of anything in Vancouver, let me know because I haven't found anything great out there. I have yet to get a tour at Granville Island on two attempts. The first time, they were doing repairs, but I was graciously offered samples so I could decide what I might want to pick up at BC Liquor. Fair enough. The second time (on a separate tripto the city) they were offering tours again, but only once per day (even though the sign says TOURS (plural) daily and we missed it. The other person with me on that trip had not had the beer before, and we were flat out refused a sample from the tap (it's not a bar--the taps are there for customer samples). There's supposedly another brewery in the city, but I'm not sure what it is (anyone out there?) The brewpub that was once apparently in Horseshoe Bay, near the ferry terminal, is no more, but there is a pub with a few decent ones. Try the Okanagon Spring brews, particularly the Stout and Porter. Skip the underhopped pale ale. If you want to see brewpubs in BC, cross over to Victoria. Spinnakers is the first. I understand they've changed brewmasters at least once, and what I had a couple years ago didn't live up to the reviews of a club member who hadbeen there years before. Still, it's a nice place and the beer is FAR from lousy. While we were having dinner there, I asked a waiter if there were any other brewpubs in town. He said we'd probably find many of the Spinnaker's staff at Swan's when they were done with work. The beer there was (one that visit anyway) better, but the food and service were worse. There's another brewpub (or "cottage brewery" as they're often called) nearby in Saanich. They were planning to bottle, pending licences, when I stopped in. Don't remember the name, but the road to it was signed off Route 17 (?) Hope this helps. I hope also to hear about any decent places in Vancouver.

Date: 02 Aug 1994 10:42:01 -0400 (EDT) From: "Brian Ellsworth, 203-286-1606" <ELLSWORTH%BRAVO at utrcgw.utc.com> Subject: ring around the carboy ! (newbe questions) Subject: More newbe stuff! Hiya ! Thanks to everyone for the responses to my questions about wort coolers. It seems this is much more of a concern with all grain brews, and a bit less significant when extract brewing. Well.... I hate to say it, but i think i'm worried :) I made up a new batch about a week ago. It was a fairly expensive concoction using about 6+ lbs of a bavarian malt extract, and 3.3 lbs of a dark malt. It also has 1 lb of crystal malt, and 1/2 lb of chocolate, (roasted) malt. I mini mashed the grain, without much regard for sanitation. Seemed to me that if i was planing on boiling the thing for 75 mins or so, sanitation at this stage wasn't too important. I also thought i'd experiment with a 'heavy hopping' schedule, and added a total of 5 oz (wow!) of a variety of hops, at various times over the 75 min boil. Northern brewer for bitterness, etc.... Just as an note, we have a new water system, so rather than risk using the home well water i picked up 5 gallons of locally bottled spring water. I used a lager yeast (first time for this type) and a champagne yeast for a little kick. I've used the champagne yeast before, it's interesting, and very active. Both were a dried yeast, using a quart or so of boiled water cooled to 110F as a starter. A couple of bad things happened. 1 - I attempted to strain the wort when transferring to the fermenter. I used a boiled cheesecloth bag, and sanitized the strainer. I don't think i'll ever do this again. The combination of heavy hopping (pellets!) and the grain really clogged up the strainer. I was concerned (not worried yet!) about the amount of 'handling' this operation caused. It would be better to just let the excess hops and fine grain particles not filtered in the mash straining, settle in the bottom... oh well.. 2 - I just bought a new plastic fermenter with a spigot in the bottom. It seemed like a great idea, but now i'm not too sure. I used a plastic bag to cover the spigot during primary fermentation. BUT, when i went to transfer, apparently, a small amount to wart leaked out into the plastic. The bag was NOT sanitized... This may have started a nice bacterial growth. 3 - Argh! I'm using a 'S' type fermentation lock. After setting up the plastic bucket and putting some water in the lock i moved the bucket on the table a tad and slurp! the water got sucked out of the lock and into the wort ! Argh! The lock was sanitized, the glass i used to fill the lock with wasn't. A calamity of errors ! Then, the dreaded result! I racked to the secondary fermenter after about 5 days after the activity seemed reduced. The yeast had settled to the bottom, and the top of the wort was clear. My secondary fermenter is a 5 gal glass carboy. I tasted the wort when i moved it. I'm really not accustom to the heavy hops, and obviously, the yeast suspension level was very high, so it's difficult for me to tell much at this point. My concern is, there was pronounced bitterness, and a sour (?) taste? With so many new flavors, it's difficult to trust my novice taste buds! Now after just a day or so in the carboy, there is a hazy ring around the top of the carboy right at the level of the brew. I've never had this ring before. Is this bacterial contamination? I'm not surprised if it is. Should i just trash it, do a 24hr bleach sanitation of everything and start over? Is it possible to salvage this batch? I'm reluctant to bottle and create a batch of 'crud-ringed' bottles... -brian e. (ellsworth%bravo at utrcgw.utc.com) Return to table of contents

I would have agreed completely when I was a student at Washington University (graduated mid-1980s). Back then, the only nearby source for decent beer was asmall "gourmet" grocery/liquor store in Clayton, and even then it meant getting imports. Since then, of course, the city has Dave Miller's place, Saint-Louis Brewing, which I've visited a number of times on my two trips to Saint-Louis this year. There's also J.D. Nick's brewpub in O'Fallon, IL. On the question of what I would drink if the choices were unpleasant.... No, I don't bother at the ballpark, except our local minor league (VERY minor league) team, which serves Capital Brewery products in addition to Budswill. If I'm at County Stadium watching the, yes, Brewers. They don't have anything I'd enjoy, so why pay over $3 for it? If I'm in a bar, I might resort to a Sam Adams if it was that desperate a situation. If I'm in a music club or in a bar after, say, playing hockey, and the focus is not at all on the drinking itself, maybe I'll have a Berghoff (if I'm even that lucky) or worse, but I won't drink very much of it--only enough to be "social." In general, I'd rather have water, or at the ballgame, I'll take my parking stub to get the two free sodas for designated drivers. I don't drink for the buzz, I drink to enjoy flavour. On getting a life for censors..... The person who complained about the Doonesbury reference to Rush Limbaugh in a .sig line doesn't seem to show much tolerance for free speech. I don't think the original writer was making a deliberate attempt to inject his politics in a beer forum. The post was within the scope of a beer forum, and the .sig line probably goes out on all his email. I think that the "Dittoheads" seem to be just a little too sensitive to the slightest bit of criticism. I suppose I shouldn't be surprised.

Stevens <stevens at stsci.edu> Subject: Re: mild ale recipe request In HBD 1490, Patrick Casey (pacasey at lexmark.com) asked for help in making a mild ale. Here's an excellent recipe that comes from Daniel McConnell of the Ann Arbor Brewers Guild. It appears on page 62 of the new beer recipe collection "Homebrew Favorites" (Storey Publishing, 1994, ISBN 0-88266-613-4). (Ask me for info on this). MILD BROWN ALE ============== This is a low gravity brown ale that has moderately sweet palate, but plenty of chocolate, nutty flavor. This is my personal favorite recipe for fast-making, fast-drinking beer. It is not a competition style beer, due to its low gravity, although I think it would do well in the "mild" categories. It is best if it is carbonated at a low level. The flavor peeks in about 4 weeks, so it should be consumed very quickly. Yield: 10 gallons Total boiling time: 60 minutes O.G.: 1.034 9 pounds Briess 2-row malt 3/4 pound light crystal malt 1 pound Munich malt 1/2 pound chocolate malt 2 ounces black patent malt 7/8 ounce Northern Brewer hops (10% alpha, boil 60 minutes) 1/2 ounce Cascade hops (5.9% alpha, boil 20 minutes) 1 ounce Hallertauer hops, steep 3/4 ounce oak chips, in boil 20 minutes Yeast Lab A01 Australian in a pint starter 1 cup, corn sugar for priming Single infusion mash at 154 F for 45 minutes. Draw off thin mash, boil, and return to hit strike of 170 F. Add the chocolate and black malt at mash-out. Sparge. Bring wort to a boil and add Northern Brewer hops. Boil for 40 minutes and add Cascade and oak chips. Boil another 20 minutes and turn off heat. Add Hallertauer. Cool, transfer to primary fermenter, and pitch yeast. Ferment 5 days at 68 F.

Im not sure about mechanical stirring, but I do not believe that any rousing of the primary fermenter is going to oxidize your beer. Theres just too much CO2 both being evolved and in solution of the beer. The key is to minimize any splashing of the beer surface, which could stir in O2. If you were introducing O2, it would likely show up in the beer. This is certainly a great type of yeast for cask conditioned ales. Once you are satisfied with a recipe and know the terminal gravities, then it is a game of racking the beer into the cask when the terminal gravity is within 1-2 Plato, depending on the amount of carbonation one wants in the cask. The fact that it slowley drops the last few degrees is a key reason that the yeast is ideal for cask ales. Think about how quick a brewer would need to be if this technique were used with American ale yeast, 1056. > Subject: mild ale recipe request I would suggest the following. English Ale Malt for OG of 1.055 (13.8P) 1/2 pound of UK crystal some brown malt, or a combo of more crystal and a touch of chocolate. Mash at 158 for one hour with no protein rest. Boil wort 1.5 to 2 hours or longer, depending on amount of carmelization desired. Counterflow chill and dilute to 1.034 ish (8.5P). Ferment with London ESB and serve on cask hand pump!. > > P.S.

Animals were, until recently non patentable. Genetic engineering has changed all of this. For a product to be patentable it must be non obvious to one of ordinary skill in the art, and serve a useful purpose, ie work. For a yeast strain to be patentable it would have to have been modified/constructed in some fashion to be different. This could include the process of genetically altering the DNA so that the yeast could metabolize non traditional fermentables (can you say dry beer?). Now, this is not sufficient in and of itself. A Patent Examiner (I used to be one in a former life), can take the "teachings" of another patent, say the one that describes how to genetically alter DNA to do a similar result as is claimed in the application, and combine it with another reference to result in an "obviousness" rejection under section ??103??

Trade secrets are an entire diff bag of hops. Patents, lose thier protection after 17 years, while trade secrets last the life of the secret. Thats why Coke has never patented its formula, it would have lost it around 1910. Fortuneatly in brewing this kind of "secret yeast" is nonsense. There are just not that many strains that meet the brewers requirements.

If you are down to the 7-8 gallon size, you might as well use one or two BrewCaps, or whatever the upside down Kinney contrap is. If you get a price on a 1.5 BBl SS uni, let me know. I am not sure of the value that a uni will provide over a straight cylander unless you are intent on making lagers. The price diffs are just too high for the return.

I'm not a die hard homebrewer yet, so I usually just scan the digest. Anyways... The other day, I bought a four pack of Bartles & James wine coolers. At least I thought they were wine coolers. Its probably been 3-4 years since I've done this. At home, I noticed that wine is no longer an ingredient. Now, the fine print says "Refreshing MALT beverage." Hmmm. Strange. Does anyone know about this? It tastes the same as I remember, and doesn't have the slightest hint of beer. Do they brew an un-hopped beer, and then add flavoring?? Just sitting here wondering...

This is true, and shouldn't be an oxidation problem at all, particularly for those using carboys. There is, after all, a big blanket of CO2 there and some vigorous agitation of the carboy for a couple of minutes should help get things going. I've been raving about this strain for months now, and consider it one of the best ale yeasts available. It seems to go through an interesting process after a couple of weeks in the bottle, where a signature level of diacetyl appears. This is not, I hasten to say, a nasty diacetyl, but rather a warm, buttery note. If you've ever had a good serving of Fuller's ESB, you'll know what I mean. - --Jeff Return to table of contents

Sazz are not generally used for pale ales. However, for any of you out there flaming poor Doug, have you tried it? Hmm? I would bet that his pale ale is excellent. What some people fail to recognize is that isohumulone is not everything in a hop, and more is not necessarily better when it comes to %aa of hops. As a bittering hop Saaz would not impart its usual spiciness, but would impart its wonderful vegetal flavour. You see, hops are not simply volatile aroma and flavour components and alpha acid. They also contain a whole lot of subtle plant characteristics, many of which remain after a long boil. If you want that english bitter flavour, you have to use tonnes of low-alpha hops, rather than a pinch of high alpha hops, in order to get that earthy, vegetal background note. Try it out. And think about the hops as a whole, not simply as a number on the bottom of the pack. Remember, high alpha hops were devised by big breweries who a) want to spend as little as possible on their product and b) want as little flavour contribution from the hops as they can manage. *-Ed Hitchcock---ech at ac.dal.ca---* Mares drink Grolsch and does drink *-Anat.&Neurobio.---Dalhousie-U.-* Koelsch and little lambs drink Lambic. *-Halifax--NS--Can---------------* Ed'll drink Lambic too, wouldn't you?

If it had been any other hop in the world, Doug, you probably wouldn't have gotten so much flack for it. Its just that Saaz is highly regarded as a finishing hop for the finest lagers. Many people though, including myself, using "finishing" hops for bittering, since they seem to give a less harsh bitterness compared to high alpha hops, even when the same IBUs are in the finished beer. BTW, 4.6% AA is high for Saaz, but certainly not considered a high alpha hop. There are some varieties as high as 15%; I think anything over 9-10% could be considered a high alpha hop.

If the purpose of AHA is to support the HB shops, fine, but don't pretend to offer "specials" to members that are offensive.

Date: Tue, 2 Aug 1994 10:25:15 -0700 From: bgros at sensitivity.berkeley.edu (Bryan L. Gros) Subject: Bitterness calculations Regarding the discussion of hopping formulas, I think they should be used as a reference. The formulas, whether it is Rager's or Garetz', are an attempt to estimate the number of IBUs in a beer. Since homebrewers have no practical way to measure the actual IBUs in their beers, we have no way of knowing which formula is the best. Glenn's research sounds like a good attempt to improve the situation. I think most of us use the IBU estimates as a relative scale. After a few batches, we know about how bitter a beer with 40 IBUs (estimated) will be. Most of us have some kind of calibration in our heads for our tastes and our equipment of what "40 IBUs" mean. If you don't have enough experience yet with IBUs in your beers, Eckhardt's book gives the IBUs in quite a few commercial beers. So use Rager's formula or use Mark Garetz', but be consistent and you should get consistent bitterness. I noticed a big improvement in consistency when I switched from using Papazian's HBUs to IBUs. - Bryan bgros at sensitivity.berkeley.edu - Bryan bgros at sensitivity.berkeley.edu Return to table of contents
