At the end of the boil I had 5.5 gal at 1.047 which is approx. 32.3 pts/lb/gal. I crush the wheat rather more fine (+ 1/2 turn on the old Corona) than the barley. (no husk to worry about with wheat) Lots of small bits and a good quantity of flour. The flour pretty well seems to disappear during sacharification. >Since my latest visit to Belgium last month, I am getting real anxious to brew >an authentic Belgium Tripple.

I would assume a fresh bottling yeast is required. > I suspect the amount of sugar is too high by about a factor of 2. For 10 gal., about 2-2.5# of straight candi sugar (if it's light candi), or 50/50 sucrose and dark candi would be just about right. Yeast is a tricky subject. One needs a yeast that can tolerate the alcohol, but yet is not *too* attenuative. I've used Chimay yeast with some success (although I still haven't concocted a dubbel or trippel that I'm altogether happy with). The yeast was cultured dregs, not Wyeast Belgian (which may or may not be Chimay). I've gone as far as 9% with it, without having to employ fresh yeast at bottling (although your mileage may vary). An acquantence once tried to culture from the dregs of Duval. I strongly suspect one would have to plate it out, as the starter had a truly *vile* odour about it. He *was* careful, BTW. However, in a matter of a couple days the starter had a *strong* barnyard droppings odour. I've always wanted to try Wyeast European (1338?), but will defer to anyone who has employed it in a strong ale. =============================================================================== Todd Enders - WD0BCI ARPA: enders at plains.nodak.edu Computer Center UUCP: ...!uunet!plains!enders Minot State University or: ...!hplabs!hp-lsd!plains!enders Minot, ND 58701 Bitnet: enders at plains =============================================================================== Return to table of contents
Date: 29 Jun 1993 15:33:01 -0500 (EST) From: STROUD%GAIA at leia.polaroid.com Subject: Belgian Tripel Discussion and recipe Jim Busch asks about possible recipes for a tripel. The Trappist abbey of Westmalle was the first to introduce the Dubbel and Tripel style. Their Dubbel (1060 OG, 6.5% alc. by volume) is a dark, amber-brown color with a rich maltiness and a hoppy dryness in the finish. A more impressive beer, and one that they are better known for, however, is their stronger beer called Westmalle Tripel. This is a very pale, strong (1080 OG, 8% alc.) ale, obtaining its fermentables from pilsner malts and candy sugar. It is hopped with English Fuggles, several German varieties, and Saaz. After several months warm maturation (50deg F) in tanks, it is re-yeasted and bottle conditioned, yielding a beer of great complexity. Although Westmalle Tripel is the classic brew, other excellent varieties of Tripel include the Trappist-brewed Koningshoeven, and the abbey varieties from Leffe, Grimbergen, Isebart, and Bruges, among others. They all possess the similar Tripel characteristics of a pale colored, high-gravity, complex Belgian ale. The exact recipes for the Trappist Tripels are generally a guarded secret. There are those who think that small amounts of herbs and spices are added as a flavor nuance. I know a person who thinks that camomile may be an ingredient, while Jan Knoop, owner of La Vierge, a specialist beer bar in Maastricht, Holland, suggested laurel leaves! I had never seen a recipe for a tripel until a trip to Belgium & the Netherlands several years ago. There I found several copies of The National Beer Journal, a monthly newspaper published by the Nationaal Biermuseum 'De Boom' in Alkmaar, Holland. In theback of one of them was an article (in Dutch) about yeast, including a recipe for a Tripel. The original recipe was in Dutch. Here is my translation: *********** Tripel (2.6 gallon): Recipe by D. Walsh 35 oz munich malt 53 oz pilsner malt 1.2 oz amber malt 10.6 oz brown sugar 2.5 oz light candy sugar 1.4 oz hops (see varieties mentioned above) 0.11 oz coriander seed 0.07 oz dried orange peel yeast Procedure: Make a thick mash at 131 deg. F and hold for 45 minutes. Add boiling water until the temperature is 145 deg. F and hold one hour. Raise the temperature to 162 deg. F and wait another hour. Hold at 172 deg. F for 15 minutes. Sparge to collect 3.6 gallons of wort. Bring to a boil and add most of the hops, boiling them for an hour. The sugar, coriander, orange peel and a handful of the hops are boiled the last 5 minutes. Starting gravity is about 1080. ********** Notes: I have made this beer a couple of times. It yields a beer of lovely complexity. This recipe makes a beer that is borderline too dark for style and I would simplify it by substituting all Pils malt for the darker grains. Also, use corn or candy sugar for the brown sugar if you wish. The hopping rate seems about right if you use low alpha noble hops like Saaz and EK Goldings. The number of IBU's that Jim suggested is somewhat lower than in the above recipe. Some experimentation here may be necessary for your own personal taste. I think that the spicing is a necessary ingredient and adds interest to the final product. Note that it is used only at the nuance level and in quantities so small that you should use a gram scale for accurate measurement. Do NOT overdo the spices if you use them, you only want a subtle touch. As for the yeast, you are somewhat limited to what you have available. I agree with Jim that Wyeast Belgian isn't appropriate (too banana-y). I have experimented with Westmalle yeast cultured out of a bottle brought back from Belgium, but it behaved as if it were a bottling yeast. Duvel is also reported to be a bottling yeast. I think that La Chouffe would be a good yeast to try, as might the Celis yeast if you can get your hands on some (they use it for their Grand Cru). Has anybody given the Corsendonk Monk's Pale Ale yeast a try?? The range of yeasts from the New Belgian Brewing Co. in Colorado might also be of interest if you can get your hands on them. So a 10 gallon batch might look something like: 22.5 lb Belgian pilsner malt 3.25 lb corn sugar 2.8 oz Saaz leaf hops (alpha ~ 3) 2.8 oz EK Goldings (alpha ~4.5) 12.5 grams coriander seed 8 grams dried orange peel Assuming 30 pts/lb for the malt and 44 pts/lb for the sugar, you should get an OG of ~1.080. Good luck and let un know how it turns out. Steve Stroud Return to table of contents

And he's the kind of person who would sell. Worse things could happen. As a side note (heh) for those of you in New England, in the June 23-July 6 edition of Face Magazine, a music-oriented newspaper published in Portland, Maine, there was a full page ad by Anheiser-Busch about "quality", "natural vs. artificial" ingredients, and "a major competitor ... willing ... to slander the entire brewing industry...". Of course, nowhere in the ad are the words malt, hops, yeast, water, grain, or anything else involved in the actual *brewing* of beer ever mentioned. Just a FYI.

Perhaps the brewmasters and food chemists at Anheuser-Busch have worked so hard to remove all traces of beer flavor from their "beer" that they have forgotten how to brew real beer. Actually, the fact that the industrial megabrewers are taking notice of beer with flavor is a good sign. All we have to do now is to encourage the good brewers to keep giving A-B the finger. Al.

Date: Tue, 29 Jun 93 13:19:33 PDT From: macdonald at a1vax.enet.dec.com Subject: Electrim Bin A few years back I bought an Electrim Bin in Canada. It's a heat resistant plastic pail capable of holding about eight or nine U.S. Gallons, made in the UK. It has a built in heating element, with a thermostatic contol with a scale of 1 through 10 I think, with a mark for "boil". I have used it with what I think of as "mixed success" in both mashing and in boiling the wort. In both cases the source of the problem seems to stem from the inability of the heating element to maintain a steady temp. For example, in boiling the wort, it will shut down for a minute or two, the wort will settle back, then it will start up, and the wort will froth and bubble furiously etc etc. Now, the advantage is that, with the portable Electrim Bin, in the warmer weather I can do mashing and boiling out in my garage, away from the kitchen, where I get complaints from other family members about the odors associated with brewing. I love the odors; the rest of my family do not. They love the final result, just don't like the odors associated with brewing, particularly the hoppy stuff that goes with the boil. The last brew I made with it was an extract "Canadian Ale" that had the target OG, fermented out in primary and secondary as expected over about 12 days total at normal temps, but wound up with a strong off taste that I can't identify in words, not bad enough to trash, but only good enough for me to drink, and then goes best with some other strong taste, like chile or a pizza with onions or some such. Also, this batch is a suspect in the "headache" department, though I am still tracking that down as a try a few more bottles. I haven't kept accurate records, but my sense is that brews I have made with the Electrim Bin have not been as good as stuff I have mashed and boiled on the stove where I seem to be able to keep a steadier temp. I'd be interested in hearing of other people's experiences with the Electrim Bin. I have just become a HBD reader in the last three months, so don't know if this is a topic covered somewhere already in the conference. In any case, your experiences would be helpful. I don't want to try using it again if others have also had bad experiences with it especially in boiling the wort. Regards, Bruce MacDonald Return to table of contents

Date: Tue, 29 Jun 93 09:27 EDT From: gcw at granjon.att.com Subject: NJ Brewpub News The bill (A-2354/S-614) to legalize brewpubs in the Peoples Republic of New Jersey has passed the Senate (35-1) and will now go to Gov. Jim (the tax man) Florio for final signature. I do not know how the original bill was compromised to get through, but there were rumors of very low volumns, no distribution outside brewpub and a copy of the Pennsylvania law where a brewpub can only serve what they make (ie no other beer, wine or hard booze). The public statement read "The measure (A-2354/S-614) would create a restricted brewing license for places where beer and ale may be produced and sold for consumption and would dedicate the tax proceeds to the prevention of alcohol and drug abuse". I believe the license fee will be $1000 and $500 more for every 1000 barrels to a max of 3000 barrels. One person can only hold 2 licenses and the resident municipality can bar brewpubs, but the brewpub can appeal to the ABC (Alcohol Beverage Control) following a public hearing (ain't politics fun!). NJ figures it will raise $22,700 in annual fees based on the national averages of 5 brewpubs producing 950 barrels each. Three cheers for the sponsers of the bill - John H. Ewing (he also sponsered the homebrew bill that passed last year and came down to NJ's first homebrew contest and had a couple), Walter Kavanaugh and Jack Penn all republicians from Somerset County.

Date: Tue, 29 Jun 93 14:09:33 PDT From: Darryl Richman <darrylri at microsoft.com> Subject: re: High Gravity Brewing Jim Busch asks about experiences with high OG brews that are diluted in the fermenter. This is what I do when I make Mild. I recently brewed 12 gallons of wort at about 1.068 gravity and then immediately boiled and cooled an additional 13 gallons of water, to make a total of 25 gallons of Mild at an adjusted OG of 1.032. Caramelization is one factor here, it allows more sweetness to be retained in the final beer (and a higher final gravity -- mine finished at 1.011). Along with caramelization comes increased melanoidin formation with the concentration of reducing sugars and amino acids. This will tend to emphasize the malt character in the beer. (Decoction mashing can have an even bigger role here.) As Papazian notes in one of his recent columns in Zymurgy, going through the primary at a very high gravity can really enhance the production of esters, leading to a more characterful beer even when diluted in the secondary (or at packaging). --Darryl Richman Return to table of contents

I've >seen yeast sold in Polypropylene vials. Al, Al, Al! Don't be so frightened of plastics. Plastics are our friends. :-) Seriously, there is nothing that says that PP cannot be food grade. I am holding in my hand right now a drinking cup (actually a beer glass from a St. Pat's Day beer wagon) that is Polypropylene. It is made by Comet, item PF14, from Chelmsford, MA. I also don't think that PP yeast vials are going to poison a 5 gallon batch. Even if the plastic had serious leaching problems (which I doubt), the dilution after several starter solutions in which the yeast slurry is pitched, would make the concentration extremely small. >Jim Busch's post reminded me of one instance of food-grade PP -- those >pleated PP filters.

Mine from the Filter Store Plus was not marked in any way other that their part number. Maybe you bought from another source. Anyway, polycarbonate, also known as Lexan (TM) can be food grade. Cuisinart food processor bowls are made out of it. Also check out the Superior Products Catalog. Many, many of their measuring cups, storage tubs, and beer pitchers are made of polycarbonate. The good thing about polycarbonate is that it is damn near impossible to break the stuff; it holds up much better than acrylic, and survives industrial type dishwashing. -jim griggers brew at devine.columbiasc.ncr.com Return to table of contents
Date: Tue, 29 Jun 93 21:35:58 PDT From: Mark Garetz <mgaretz at hoptech.com> Subject: Zymurgy Article Correction Keith A. MacNeal asked why my article on dry hopping the recent Zymurgy stated that less hop aroma was extracted from pellets than whole hops. The sentence that probably caused the confusion reads (on page 45): "You will want to use whole hops as opposed to pellets, otherwise you'll still have to let the beer sit with the hops for about two weeks..." I guess there was a typesetting mistake. The sentence was actually two sentences and should have read: "You will want to use whole hops as opposed to pellets, otherwise you'll have hop particles in your beer as you drink it. If you force carbonate the beer, you'll still have to let the beer sit with the hops for about two weeks to allow the hop oil to be extracted into the beer." Of course I wrote this before I discovered that there actually were hop bags that keep the pellet particles contained. Also, later in the article I say, "Pellets give a better aroma yield because the lupulin glands have been crushed, releasing the hop oil." I'm going to write to Zymurgy and have them print a correction. BTW, they don't believe in having their authors proof the galleys. Mark from HopTech Return to table of contents

Date: Wed, 30 Jun 93 01:01 CDT From: arf at genesis.mcs.com (Jack Schmidling) Subject: Spigots, PU >From: Bill Holman <jwh7k at uva.pcmail.virginia.edu> >Subject: What valve/pipe fitting for SS keg? > What type of ball valve/pipe fittings can be used for a drain on a SS 15.5 gallon keg? What kind of metal can be used? Iassume SS would be best, but what about brass or copper? I spent a lot of time thinking this one through both from the standpoint of the ideal for my own brewery and for something for sale to others with minimum tools or time. The basic problem presented by everything available is that they are made with tapered pipe threads. Kegs, kettles, etc. are not heavy enough to provide reliable fittings to pipe threads so they must either be welded or a compressing fitting must somehow be arranged. If one has the tools, this can easily be done by rethreading the parts with straight threads and the two pieces simply screwed together with the keg wall in between and a leakproof and structurally sound fitting results. As re-threading is difficult enough, I have chosen brass parts over SS but either is appropriate. To further keep it simple, I use parts with 1/8" pipe size because people are more likely to have a 3/8" drill bit in their tool box than much larger ones. My system consists of an aircock with a male thread that passes through the kettle and a female connector screws on this from the inside. To this is attached the removable copper tubing/ss screen via a compression fitting. For detailed info, email for "easymasher". >From: Jim Busch <busch at daacdev1.stx.com> >Subject: High Gravity Brewing >I realize one needs to take into account theadditional caramelization in the kettle with the increased sugar content, but has anyone done much of this. I am especially interested in the idea of brewing pale ales of OG 1.065-1.070 and adding water to result in a 1.055 in the fermenter. As I now have a ten gallon keg and only a ten gallon fermenter, I brew and ferment 8-9 gallons and top off the keg with boiled water at kegging time. The end gravity is easy enough to predict and adjust for. I don't see any reason to ferment the water and I need the head space in the fermenter. I don't think this is quite the same as the infamous "beer concentrate" of previous discussions but it is dangerously close. The key lies in what went into the "concentrate" and if it is strictly Reinheightsgbot, when the water is added seems incidental. >From: korz at iepubj.att.com >Subject: DMS and PU >A few days ago, Jack wrote about his Pilsner Urquell clone that was brewed as closely as possible to Darryl Richman's description of the way Prazdroj Pilsenski (I think that's the spelling?) makes PU. >Well, last night, I had a chance to try some of this beer. A good attempt, I must say!..... >The beer had been fermented and lagered at 40F for a while (I forgot to ask how long). Two weeks primary and two weeks secondary and about a week in the keg. > Perhaps a longer lagering (and maybe if it was lagered at 32F as in Pilsen) the DMS level would be a bit lower? I suspect that time is more important then temp but have no way of checking both. I did bottle a sixpack for tasting in about three months which is what I recall PU does before shipping. >From: Darryl Richman <darrylri at microsoft.com> >Subject: re: Wort Chilling >While it is true that the hot, bittered wort at PU is cooled slowly in a coolship, which could engender a great deal of DMS production and retention from latent S-Methyl Methionine (SMM), one must consider that the preceding boil is exceptionally long and it is likely that most of the SMM has already been converted to DMS and then evaporated off (see Fix's "Principle of Brewing Science" for a lot more detail here). For the record, I boiled this beer for 4 hours just as in your article. I started with 16 gallons of wort and ended up with 7 gallons of beer. > *Some* DMS flavor is, in fact, a defining character of lager beers, and adds to the crisp flavor profile. As a sequel to the story, we had lunch Sunday with the Parsons from the Malt Shop at Edelweis where PU is on draft. I bottled two bottles of my clone just before leaving and ordered 4 glasses of PU and two empty glasses and did a real live comparison. The color was identical. My beer was a bit harsher (for lack of a better term) and the DMS became more obvious if a small amount was left to warm up in the bottom of the Pilsner glass. We all agreed that the PU was at least marginally better but that repeating the experiment in three months would definately be informative. js Return to table of contents

(Bear in mind, especially Markham, that I know this is a quoted article, so I'm commenting on *it*. No flaming diatribe is intended. Thanks for the excerpt, Mark.) Beer made in Japan tastes "dreadful"? Funny, it tastes like competently- made, lightly-hopped lager to me. There may be some quirky terminology, like "draft" for unpasteurised beer in bottles, or "stout" for pale lager beer with a bit more body than some, but hardly "dreadful", especially in com- parison to some of the American industrial beerlike liquids. And then there's Sapporo's "Black Beer", which is most definitely *not* dreadful. Sounds like more brewing chauvinism at work here. >Sure glad we don't have to pay prices like that. Yeah, so am I. So are most Japanese, 'cause they don't always. I friend brought back a bottle of Budvar/Budweiser, bought at a specialty drinks- shop in Okinawa. He paid an obscenely high Y320 for it - an astonishing $2.50 a bottle! Yow! Seriously, the article was interesting, if for no other reason than to display a bit of good old Western cultural bias ("Gol durn, them Japanese sure pay high prices. How can they afford anything?"). The average consumer in Japan deals with high enough prices for many things, but beer is not usually that outrageous, and imports can be found, often in sur- prisingly good condition and at not-exactly-astronomical prices. On the other hand, a bunch of businessmen with a bit of extra money on their hands seem to have found a novel - and fun! - way of getting rid of it, and at least they're drinking some good beer - although I'm not sure about paying $78 for a 'vintage' bottle of Gales Prize Old Ale! On the other hand, those entry dues sure are high. Not surprising in a country where business associations often blur the distinction between commercial and social interests, and where memberships in such associations are often perceived as being more valuable than gold. ObHomeBrew: Because of the Japanese quirk of not letting one brew beer unless one is going to make at least two million hectoliters, an enterprising importer is selling homebrew equipment and kits, with instructions to heavily dilute the malt extract, or to only use a small amount, so it makes a legally "non-alcoholic" beer. Of course, anyone who actually buys the kit receives subtle verbal advice to ignore the instructions if a proper batch of homemade beer is desired ^_^. - -- __ | | __ /\ \ | Don Scheidt | /\ \ / \ \ | Boeing IASL, 777 Cab Development | / \ \ / /\ \ \ | dgs1300 at aw101.iasl.ca.boeing.com | / /\ \ \ / / /\ \ \ | | / / /\ \ \ / / /__\_\ \ | | / / /__\_\ \ / / /________\ | | / / /________\ \/___________/ | | \/___________/ Return to table of contents
Date: Tue, 29 Jun 93 14:44:40 PDT From: Darryl Richman <darrylri at microsoft.com> Subject: re: Raw Wheat protein content Al Korzonas asks about the correspondence between JX Guinard's quoting of unmalted wheat protein at 1.8 to 2.1 % and the reality that all wheat, malted or otherwise, has more than 10% protein. JX Guinard is apparently quoting the amount of "amino nitrogen," which is often interchanged with protein, and not the protein itself. (In a very simple chemical assay, protein is made up of carbon, oxygen, hydrogen, and nitrogen. It is the last item that distinguishes it from a carbohydrate, so the nitrogen content of an (organic) substance is taken as a figure of merit of its protein content.) The ratio of nitrogen to protein mass is reckoned to be 6.25, so the equivalent protein to 1.8-2.1% nitrogen is 11.25-13.75%. --Darryl Richman Return to table of contents

Great book, but it left me with some questions: 1. Where can I get "Candi" sugar in the US? Any mail order places? If I can't get any candi, any suggestions for suitable replacements? I suppose I could always plan a field trip to Belgium to buy my own 50 lb bag ... 2. It seems like the yeast selection is of paramount importance, yet the book just talks about using an alcohol-tolerant strain. Aside from the Wyeast strain, what recommendations does the net have for appropriate yeast strains? 3. How do I introduce a second yeast? In his Grand Cru recipe, Pierre states,"This recipe is great for two-yeast fermentation. First fermentation takes place with a weak attenuating yeast. In the secondary fermenter, add a second wild type, or different higher attenuating yeast." Aside from leaving my secondary fermentor outside in the hopes of pLambic fermentation, what should I use for a "wild type" yeast? How does the second yeast accomplish its aeration phase? Hasn't the first yeast already used up the avaiable oxygen in the wort? Should I just pitch with a HUGE volume of yeast and not worry about yeast propogation? 4. It appears that primary fermentation temperatures are fairly high, while secondary fermentation takes place at relatively low temperatures (for ales). Any comments from people who've attempted these styles? 5. Finally, just how long will I be required to bottle condition my attempt at a Grand Cru? With all the sugar, I get the feeling it might take awhile to smooth out the flavors. TIA Andy A Return to table of contents
Date: 30 Jun 93 08:47:11 EST From: "John Shane" <JSHANE at clover.uvm.edu> Subject: maple in beer Hi.. I tried to send this directly to the person who asked about maple in beer, but got an undeliverable mail return, so I thought I'd send it here: I am a homebrewer and (note the state I live in) a maple syrup producer. YES you can brew with maple syrup. A good ballpark conversion is to remember that a gallon of syrup weighs 11 lbs with a solids concentration of 66% (66.5% in Vermont, ...God we're independent cusses) most of which is sugar of some sort, mostly sucrose. Essentially, you can assume 66% sugar, all of which is fermentable. Syrup gives an excellent flavor to all beers (in my opinion), but some basic advice concerning syrup grades: Fancy (Grade A Light Amber in all states but Vermont (did I mention that we do thing our own way?) is VERY delicately flavored, and will be overwhelmed in almost any beer; Grade A Medium Amber is darker and less delicate, probably good in most lightish recipes; Grade A Dark Amber is darker still, will leave a more perceptable flavor, Grade B is even darker, good for beers with more robust formulations. As a first try, you might want to consider brewing "Rocky Racoon" in "THE BOOK", replacing the honey in the original recipe with an equivelent (by sugar content, not syrup volume or weight) amount of medium or dark amber syrup. Adjust further attempts to taste. NOTE: unless you spend every waking hour during spring at blast-furnace temperatures boiling sap (about 40 gals sap to 1 gal syrup) to get the liquid gold yourself, this will wind up being a very expensive habit.

I boil it for about ten minutes, put the solid stopper in it >and set it in a sink full of cold water. (Isn't pyrex wonderful?)" Pyrex (tm) is wonderful all right, but it is still possible to break it by going from a flame to cold water too rapidly. I'd try to ease the temperature transitions a bit, air cooling the flask for a few minutes before moving it to not-too-cold water. What really concerns me is the practice of stoppering the flask hot and putting it into cold water. If the stopper fits tightly, that will create a partial vacuum in the flask, and standard thickness Erlenmeyer flasks (or any other glassware that has a flat bottom or flat sides) can't handle vacuum very well (you can get thick-walled filter flasks that look like an Erlenmeyer and are made for vacuum use, but they aren't meant to be heated, so that doesn't help). Better to let clean (filtered?) air into the flask as it cools than to run the risk of imploding a flask full of very hot solution. That WILL ruin your whole day.

Does anyone have any recipes which >> call for maple syrup? How much per five gallon batch should be >> used? I made a batch using grade B maple syrup (about the same price as malt at a local coop food store), used about 3lbs, with 5.5lbs amber M&F malt syrup. Used the generic 5 gallon beer recipe, except I messed up badly in hop choice/usage, and it was overhopped. That problem has mellowed out, and it now tastes like a mildly sweeter sierra nevada pale ale, or (pick your favorite amber) hopped up with a nice maple after taste. Some book (I think it was CJoHB) mentions not to use this much maple. Grade B tastes similar to grade A (the standard stuff), but definitely doesn't compare well in a side to side comparison (a bit more water and a tad less sweet). Don't overhop! hops + maple is an interesting combination, and probably isn't for everyone (some friends like it, and others start making gagging noises... typical.) -tony - -- Anthony Rossini - grad student/statistician/hacker rossini at biostat.harvard.edu Department of Biostatistics, Harvard School of Public Health 677 Huntington Ave, Boston MA 02115 617-432-1056 Return to table of contents

It can be treated as an art, but for the best results, you must understand that it is a science and that things that you do at one step will have an impact on another step. I see a mix of levels here in the HBD. There's nothing wrong with that. I prefer to see the technical side. Theres a plethora of literature out there geared towards the general population and not enough good technical info, unless you get into the peer reviewed brewing journals. > but don't you think it is getting a bit anal, when we start breaking > down the composition of the chemicals so as to get the optimum cleaning for > the least amount of chemical.

Lewis <dblewis at jscprofs.nasa.gov> SUBJECT: Yeast culturing slants I've had a bit of trouble with my slants recently. The poured and cooled tubes look great, but when I inoculate one, the solid wort begins to shrink and pulls away from the sides of the tube. In one case, some yeast got down in the bottom of the tube behind the wort plug and when I opened the cap to relieve some of the pressure, the pressure crammed the wort slug into the neck of the tube! I don't have my notes, so I don't remember how much agar I put in the wort. (15 gm in 0.5L sounds vaguely familiar.) Could my problem be too much agar? Maybe I should fill my tubes more full so that there is a significant plug at the bottom of the tube. The tubes were clean, but maybe I should give them an acetone bath prior to filling and sterilizing to remove any trace of oils or dust. I'm open to any and all suggestions. Dennis B.

I have been > contemplating a fruit beer, and this may do the trick. But, Allan, > blueberries in beer? Let me know how that turns out. Why not blueberries? I made a blueberry brown ale last year that turned out quite nicely. The berries gave the beer a subtle, wine-like character that was very pleasant. The recipe was posted in HBD #926 (July 18 '92) if you're interested. Jim Liddil <JLIDDIL at AZCC.Arizona.EDU> and "Mark S.

There are a number of different lautering options: an easymasher, a slotted copper pipe manifold, a false bottom, a separate double-bucket Zapap-type as described in Papazian. The subject has been covered at various times here, maybe it's time for a monthly FAQ? Anyway, I favor the slotted pipe setup, since it's completely removable, doesn't require you to drill a hole in your pot, and can be disassembled for easy cleaning. I posted plans in HBD #1099 (Mar 17 '93). The description of the EasyMasher(tm) were originally posted by Jack Schmidling in HBD #754 (Nov 4 '91), and there was a lot of discussion and diagrams during March '93. - -- Jeff Benjamin benji at hpfcla.fc.hp.com Hewlett Packard Co.
