I used cultured Guinness yeast and an open fermenter for my last batch of all-grain Stout. Sure enough, I got beautifully large caulifower heads which often brought up lots of brown muck. The pancake heads did try and take over the whole house, but fortunately didn't manage to crawl out of the kitchen. Traditionally, ale has been fermented in open vats. I presume that the vigerous fermentation and abundant head cover must protect the beer. Even if it doesn't contribute to the complexity of the beer, it's fun to watch! Ifor.

I finally had a chance to try it this weekend and, while it's great to see attempts at this happening in the US, was disappointed. Comparing it to a substantial amount of other wheat beer tasted from German brewers, it was very one-dimensional (to me). It matched most closely to a wheat beer brewed by Tu:cher, also a filtered brew. In both cases, the characteristic clovey taste/odor was there, but it seemed like both brews were made to specifically emphasize that flavour only and not the other aspects of beer. I'd say it's similar to wanting the taste of chocolate and eating bakers chocolate instead of eating the sweetened stuff. I'm convinced, now, after comparing an amount of Kristal vs Hefe weizen, that wheat beer should not be filtered. Mike Zentner Return to table of contents

Some places (in Munich) I had to ask for lemon, but I'd say the lemon ritual is more particular to the tangy Northern German Weissbier rather than Bavarian Weizenbier. A local restaurant, Cafe Berlin (run by three Germans) serves Spaten Club Weiss with the lemon wedge on the edge of the glass so you can choose. I just plop it in -- squeezing gives *too* much lemony flavor/aroma, overpowering the delicacy of the beer; it also reminds me of the Corona/Sol/Tecate crowd, adding flavor to their `beer' by adding lemon :-( Bis spaeter! - -- What soberness conceals, drunkenness reveals.

In article <49 at pyuxe.UUCP> dab at pyuxe.UUCP (D Ballard) writes: >Can anyone recommend a supply house in the central NJ area? There are no brewing supply stores (or even brewpubs) anywhere in New Jersey. In fact, the legal status of home brewing in the state is uncertain. A Federal law was passed in 1979, "giving home brewing the same legal status as winemaking." [Mares, MAKING BEER, p. 21, which also quotes some of the bill.] This presumably loosened the bounds set by a previous law. However, a similar NJ law allowing winemaking doesn't mention brewing. Some Jersey prosecutors have occasionally promised that they won't enforce the "law against home brewing", but no merchant is willing to take the chance. (I've heard, third hand or so, from someone who predicts that New Jersey will be the *last* state in the U.S.A. with a legal brewpub.) A gentleman named Bush (no relation to the President or to A-B) has been pushing for a specific law that *permits* limited home brewing. (One of the details was the question of requiring a license to make wine or beer. The compromise position is that a household could make 100 gallons/year without a license, and 200 gallons/year (the federal limit) with a license that costs about $100/year, as compared to the $20/year license New Jersey currently expects for making wine. This in a state that may soon require a license to design software, as described in the comp.software-eng newsgroup.) That's not to say there are no home brewers, or no home brew clubs, in the state. There are supply shops in Staten Island and Greenwich Village. I've heard that they charge more than a lot of mail order places. I've gotten a recommendation for one of the latter: Semplex of U.S.A. (612-522-0500, 4159 Thomas Ave. North, Minneapolis, MN 55412), which doesn't charge extra for shipping most items. (They charge UPS rates for carboys and corn sugar; the prices for extract, grain, whole beginner kits (plastic bucket, no carboy, two cans of extract, and five pounds of sugar) and even Rotokegs "include shipping to anywhere in the U.S.A. and also to APO and FPO addresses.") >dave ballard >dab at pyuxe.cc.bellcore.com Paul S.

When I wash my carboys, I just put in about 1/2 gallon of warm water and about a tablespoon of chlorinated TSP, then violently slosh the stuff around a few times. The only "gunk" ever stuck in the carboy is in the fermentor, around the top; that's kindof a pain to remove, but not much. Carboys used for intermediate settling and clarifying never get very scummy at all. Hmm. I'll take this opportunity to re-endorse the cheap-beer-rinse technique of removing chlorine residue. After I wash with chlorinated TSP and rinse with the jet thing, I pour in a couple cans of Blatz ($3.49 a twelve pack!) and slosh. Chlorine residues go down the drain! - -------------------------------------------------------------------------- Mike McNally mcnally at wsl.dec.com Digital Equipment Corporation Western Software Lab Return to table of contents

We didn't go there because the beer was great (although the sandwiches are); we went because they never "proofed" us. One interesting note. I was told by a regular that McSorley's used to be a men-only bar until recently (late 70's perhaps?). Therefore, they had no ladies bathroom. NYC sued the bar for discrimination, and McSorley's had to open its doors to women. However they did not put in a ladies room. The bathroom became co-ed. I haven't been there for 6 or 7 years, but I assume they have both bathrooms now, but I don't know. Email addresses. I just moved to a bitnet only site. I have absolutely no access to internet. Therefore, if you have a bitnet address in addition to your internet address, could you please put *both* in your signature at the end of your post? I know it'll help me and I'm sure a few others who want to email folks, but who don't have the proper address. I had to mail this to a friend on internet--I could not send this post to the HBD via bitnet (the listserv process) Could someone tell me how to do it? I sent it to BEER-L at UA1VM and it bounced, saying I had no authorization. I successfully subscribed to the list via listserv, but can't post. P.S. I'm a history teacher, and I was reviewing the 1988 elction campaign, espeically the Lloyd Bentsen-Dan Quayle debate. I happened to have headphones on, and I thought I heard Bentsen say (correct me if I'm wrong) "Senator, you're no Steve Russell." Although it might have been "Richman." Any one hear this too?

The way I have usually had it served is with one slice of lemon floating on top, and a couple of grains of uncooked rice at the bottom. Weizen is traditionally drunk more in summer, since it has more carbonation than other beer and is more refreshing. The rice will give the CO2 a place to form more bubbles, similar to the little scratches sometimes put into the bottom of champagne glasses. Lemon and rice are usually left in the glass.

Finish your article. Well, I've been out of town for a bit. I'm including below the original text of the malting section of the Pilsner Urquell article. Since the article was quite long, Zymurgy had to edit it down somewhere, and the malting section took the biggest hit. (In fact, the complete story was published, with more figures and photos, as a four part series in the Maltose Falcons newsletter "The Brews & News". Since the Falcons exchange newsletters with about 50 clubs out there, you might check around and see if you can find the Feb. through May issues.) I appologize for the length of this posting, but I'm not really sure just where the cuts were made, and I feel it's better read as a whole. --Darryl Richman The Maltster's Tale To homebrewers, malt may seem like a pretty dull sidelight, an ingredient that is just assumed. And yet, how can one hope to make the finest of beers without understanding the materials required? Being the largest ingredient after water and the arbiter of mashing conditions and the source of food and nutrition for the yeast, its characteristics are extremely important to the final product. The process of malting has results that appear in the product as many subtle and not so subtle effects on the flavor and appearance: grainy, toasty and malty flavors and aromas, head retention, beer color, body, and so on. Malting is the process that takes raw, harvested barley grains and readies them for the conversion of starch into sugars in the mash. Raw barley is very hard, or steely, because the starch is locked together with a lattice work of protein, called a matrix. If raw barley were crushed and enzymes added, very little starch would be converted to sugars because most of it would still be locked up in the matrix, unavailable to the enzymes. Even the germinating plant cannot reach the starch in this form, so it makes protease enzymes that slowly cut away at the matrix. As the plant grows, more and more of the matrix is destroyed; brewers call this process modification. As modification proceeds, the plantlet is also producing its own amylaze enzymes to reduce the starches to digestible sugars. It is both of these processes that the maltster wants to encourage. However, as it grows, the plant uses its enzymes to make sugars which are then used as fuel for its growth. Overmodification means reduced extract. The same grounds that contain the brewery include 2 malting works. In former days, most breweries did their own malting, but over the last century specialized companies have come to take over the malting process instead. Pilsner Urquell has adopted a hybrid approach: the maltings are run as a separate company, but the close proximity of their largest customer, and under the former communist system, the fact that they were both arms of the same "holding company," means that the maltings are dedicated to producing the malt that Pilsner Urquell specifies. They also supply malt to many of the other breweries, including Budvar. Jaroslav insists that Pilsner Urquell gets their best product, however. There is a new, larger maltings 2 kilometers down the road as well, which was built in 1988 and opened in '89. We walked over to the nearest malt house to see how they work. Curiously, Jaroslav did not know a great deal about the maltings--he had to get a guide for both of us. He explained that he is in charge of the brewing activities (and previously had run the fermentation cellars), but the brewmasters and the maltsters don't get together much. The maltings produce 50,000 tons of malt each year. If you are an all-grain brewer, and you get a pretty reasonable extract, that means you could make over 2 million barrels of beer at Pilsner Urquell strength. The grounds include storage space for 70,000 tons of barley and 15,000 of finished malt. The compound has a rail line passing through it, which not only facilitates delivery of the finished product, but malt as well, and there are also facilities for loading trucks. The Process The Pilsner Urquell maltings are based on a gravity system, not unlike that used in brew houses. The dry barley comes into the plant and goes into a storage silo. From there it is cleaned of dirt and foreign seeds, and brought to the top of the 6 story building, where it goes into the first of a series of steep tanks. The steep tanks provide the environment for the barley seeds to wake up and begin to grow. Barley has a natural dormancy that must be overcome before it will germinate. It has evolved this mechanism to preserve the seed through the harsh winter and into the next spring. The steeping process is repeated 3 times in order to stimulate the seed to germinate. Each steeping takes about 21 hours. The steeping process begins by filling the tank with cool water and pumping oxygen through. Although green plants get by employing photosynthesis, which breaks sugars and CO2 into O2 via sunlight, the germinating plant falls back onto respiration (sugars and O2 to CO2) as a means of developing energy, so the water must be highly oxygenated to keep the germinating seeds from starving. (Fermentation, with which we are familiar, breaks sugars into alcohol and CO2, without employing O2; however, the yeast must go through a respiration phase to reproduce quickly.) Each steep holds the barley under water for between 4 and 6 hours and then drains the water away for most of a day. This simulates rainfall, and is how the maltster fools Mother Nature into thinking that spring has arrived. As germination begins, with each seed respiring, a lot of CO2 is given off. Every 2 hours a huge fan pulls the heavy CO2 out of the tank from underneath; it is naturally replaced with fresh air. This goes on for about 15 minutes. At the end of each steep cycle, the grain is released into a new tank waiting below it, and the process begins again. Finally, after 4 days (and four stories' drop), the now-germinating barley ends up in a germination bed. This is a long, shallow, rectangular frame that holds the barley as it grows. It is here that the barley will grow to its final stage before kilning. There is a cross-member that runs over the short dimension and is motorized so that it can proceed from one end of the frame to the other. On this member are a series of screws that slowly turn, lifting and separating the germinating grain so that the roots will not grow together and form an impenetrable mass. This also aids in the air flow through the bed, which is held at 60* F and 47% moisture. The barley is carefully watched, until the acrospire, or growing tip of the barley plant, reaches 2/3 to 3/4 of the way around the long dimension of the seed. It is at this point, after about 7 days, that the barley is sufficiently modified, and the germinated plantlets are moved off to the kilns. For comparison, in English malt the acrospire is usually allowed to grow all the way to the top of the seed; most 2 row malt is allowed to reach the 3/4 point before germination is stopped. The kilns are special closed boxes with hot, dry air blowing through them. The service entrances have airlocks to prevent losing heat if someone must inspect or repair them while they are in operation. The maltings has three of these boxes, and they can dry 50 tons of malt at a time. The wet malt is dropped (once again) into a kiln to a depth of 85-90 cm (just under a yard). The hot air is held at 80-81* C (176-178* F) until the malt reaches a moisture content of just 3.5-4%. The process takes about 20 hours. After drying, the malt is cleaned again--this time to remove the rootlets from the malt. The malt produced has a color of 3.8-4.0 EBC (about 1.9-2.0* Lovibond), which is pale indeed, but not as pale as most 6 row malts, or even 2 row malts in this country. In fact, this is very near the figure often quoted for English Pale malt. This is one reason that Pilsner Urquell is not as light in color as American or even many continental lagers. The malt ends up with 11.5% protein, on average. (Barley protein figures vary with each crop, and can have substantial swings.) This is a relatively low figure when compared with American crop figures, which tend more towards 12.5-14%. The protein number is a figure of merit with respect to the amount of adjuncts that can be added to the mash without affecting yeast health. Since Pilsner Urquell is an all malt beer, this is not, of course, a concern. It can also indicate potential haze and heading problems. Return to table of contents

Date: Mon, 19 Aug 91 20:04:29 bst From: Conn Copas <C.V.Copas at loughborough.ac.uk> Subject: Re : The great CaCl2 debate Seeing I provoked some of the current debate, I'd better set the record straight. Hard water contains lots of dissolved mineral salts. Salts contain both a positively and a negatively charged ion, eg, calcium (++) and chloride (-). Depending on the type of beer being made, some of those ions are more or less desirable. Calcium (++) ions are universally regarded as being good for pale ale and bitter production, for a whole host of reasons, including the fact that they increase the acidity of the mash by an indirect process. Ditto magnesium (++) ions. Chloride (-) ions in small amounts are good for bringing out the sweetness in beers. Most salts which contain chloride ions taste 'salty'; this is not a function of sodium (+) content. Carbonate (--) and bicarbonate (-) ions are alkaline, that is, they react with anything which is acidic and thus reduce the total level of acidity. For various reasons, these ions are dreaded by all brewers except those who make very acid beers using roasted grains. Let's forget about stouts for the moment. Hard water which has flowed through gypsum contains calcium++ sulphate--, both good news. Hard water which has flowed through limestone usually contains calcium++ and/or magnesium++ (good news) bicarbonate- (bad news). How can the beneficial half of the salt be retained whilst disposing of its undesirable negatively charged partner ? Simple, react the salt with a controlled amount of acid, at room temperature. The products are water and carbon dioxide, not a precipitate. Less simply, heat the untreated water. The bicarbonates- will be transformed into carbonates-- and will precipitate (good news), along with an equal molecular amount of calcium++ and/or magnesium++ (bad news). Therefore, you might wish to supplement the calcium++ content by adding some calcium++ chloride-. But the treatment is starting to get complicated. Most of the time, adding calcium chloride will precipitate nothing, unless there is a soluble carbonate salt present, such as that of sodium+ or potassium+ (most unusual). Calcium chloride could be a better choice than table salt for bringing out the sweetness in a beer. Notice that most water authorities quote the total alkalinity as the 'equivalent' of ppm calcium carbonate, even though this salt is never present in large amounts. It would be very unusual to have both a high bicarbonate ion content and a low calcium ion content, unless (a) the alkalinity is mainly due to magnesium salts, or (b) some drastic treatment has already been performed. Can't say that I have read Miller, but ... Even the late, great Dave Line had his moments. For example, recommending gelatine as a fining agent (has anyone ever found this to work) ? Or the occasional 'any yeast will do' philosophy. Clear as mud ?

It's pretty simple, it calculates the O.G., color, and IBUs (among other things) based on the grains and hops. It's kind of fun to play with, and helps to zero in on the right quantities to get desired results. I've ftp'ed it to ftp.uu.net in /tmp/bw.sc.shar. I believe it will live there for a while. I'd like to send it to the homebrew archives at mthvax, but I don't know how. If somebody knows how to do this, would they please send me some mail? If you can't find it in either place, please mail me and I will send it in shar form via email. Return to table of contents
