Couch) Subject: Re: Hops and disasters I have finally harvested the hops and got 1 lb dry weight out off the cascade, 0 out of the Williamette, 4 oz off the the Nugget and 0 out of the Mt Hood, all of them 5 months old. The Williamette has this weird bug that wilts all the leaves from the root up, the leaves turned brown and papery, but they don't fall off. None of the other hops had the problem. The first batch of dry hops have now been used in the Cascading Hopping Spider AltBier, not that using Cascade is true to style of an Alt, and most of the spiders are removed from the cones. I will post the results when the beer is ready. As for brewing horror stories, none of mine could top what's out there. All the damage were confined to the kitchen and storage area in the basement. The funniest one is the probably the ballistic air-lock. It hit the celling and spewed all over the place. The last one was when I brewed with my brewpartner a couple days ago at my house and it was Laurel and Hardy time. I started brewing after work, and of course we decided to do 2 batches at once, fools! so at 9pm, we started sparging, at 10 pm, we started to brew, after painstaking working out the recipes we added the hops to the wrong batch, and at midnight,we put in the finishing hops in the revised recipe. At that time, we realized that we forgot to add munich malt to one of the mashes. We then carried a full 5g pot to the basement and use the chiller. So there was a trail of hot beer all over the kitchen and down the basement. The chiller attachment doesn't hook up tightly on the washer hose so there was a small fountain and one of us had to keep a hand on it to stop in from spraying. When it was done, we realized that we forgot to add Irish moss, so we went back upstairs and added it to the second batch. We then repeat the last process at ~1am with the second batch. It was then time to put stuff in the fermenters, my partner for some reasons decided to pour the stuff into the carboy with a funnel, I wanted to use a hose, but he insisted on pouring, so I let him (We both wanted very much just to finish the hell up and go the sleep), halfway down, the filter of the funnel got clogged, after some more struggle and losing pints of beer to the floor and some trub into the carboy, we got all the beer into the carboys at 2 something am. At this point, my partner decided to drive home cos he had an early meeting the next day. So I had to mop up the floor, and of course the mop broke. Well, anyway stuff got cleaned up the next day, and the beer is bubbling, and the next morning, I realized that we forgot to take an sg reading. We are not normally this dingbatty, but we just moved brew location and had too many home brew with our deep dish pizza. P. Return to table of contents

The flavor seemed to be fine going into the bottles, though it was a bit sweet. I suspect that it has to do with the corn sugar I put into the wort with the dry malt. I immediately started another batch. This is an export ale. I wanted it fairly hoppy, so I boiled the wort longer, about 45 minutes, and left out the corn sugar. I'm not inclined to use the sugar again at any rate given what I've been reading. My question is, how soon should I start seeing bubbling through the airlock? Last time it began within 12 hours. This time it hasn't started after that much time. I know I'm being a bit anal retentive, but I checked before I came into work and just thought I'd ask. One think I did differently this time was to just throw the yeast on the top on the wort without stirring it in. Last time I stirred it in. If it doesn't start bubbling away what can I do to move it along? Thanks in advance. You all have been very helpful to me a couple times in the past. This is an easy one, I know.

Lyons" <LYONS at adc1.adc.ray.com> Subject: Hydrometer reading as a function of temperature Someone a little while back asked about hydrometer readings as a function of temperature. The brochure that came with my hydrometer had the following correction table (add correction to reading): Temp in deg. F Spec. Grav. Correction - -------------- ---------------------- 50 -0.5 60 0.0 70 1.0 77 2.0 84 3.0 95 5.0 105 7.0 Example: A measured specific gravity of 1.035 at 84F translates to a corrected (relative to 60F) specific gravity of 1.038. I plotted the above data and fit it to a third order polynomial. The fit was quite good (R=0.99994). corr. = 6.66365 - 0.34722*T + 0.00474726*T**2 - 1.3431775E-5*T**3 With this equation one can write a short program that takes the measured specific gravity, and temperature, and outputs the relative specific gravity at 60F. ...

Date: Fri, 4 Sep 1992 10:02:24 -0400 (EDT) From: YATROU at INRS-TELECOM.UQUEBEC.CA (Paul Yatrou) Subject: Wyeast Belgian Ale (how not to prepare a starter) Hello all, last week the cooler weather started to set in and I decided to make my first batch in over four months. I chose a Belgian dubbel recipe (pg. 122 "Belgian Ale", Pierre Rajotte, all-grain), cracked the grain Friday night, and promptly realized I hadn't prepared any yeast! I pulled out an 8 month old Wyeast Belgian Ale packet out of the fridge and popped it. Now, 8 months old, let's see... that should take about one week before it would be ready, and I wanted to brew the next day. Hmmm.. So on Saturday I mashed, sparged, boiled, and cooled wihtout any mishaps and by 3PM it was time to pitch. The packet hadn't budged at all. I decided to wait till night time. At 9PM I started fretting about the "unprotected" 5 gallons of wort sitting in my closet and pitched the far-from-ready Wyeast. On Sunday morning I rushed to the closet and ... nothing. Sunday night, NOTHING! Monday morning ... de nada. I started to worry a little, and thought of throwing in some dry Whitbred ale yeast, but it was time to go into work. After work, as I was climbing up the stairs to the apartment I heard the distinctly heavenly sound "glub ... glub ... glub". I rushed in and, low and behold, there was a party in my carboy. It's been fermenting wildly all week long now. The closet smells like a giant Chiquita, there's still a thick krausen, and I'm a happy camper. I seem to recall a thread on HBD about 2 months ago about the characteristics of the Belgian Ale Wyeast, namely banana esters, drawn out but active primary fermentation, preference to lower temperatures (below 65F if possible). So, I guess the jist of all this is: RDWHAHB, have confidence in your brewing technique, and trust your Wyeast (even if it's old)!! Of course, I'm not affiliated with Wyeast etc..., I'm just a happy camper. Paul Yatrou. Return to table of contents
Date: Fri, 4 Sep 92 10:21:08 EDT From: Alexander R Mitchell <ARMITC01 at ULKYVM.LOUISVILLE.EDU> Subject: Dry Yeast starters / brewing disasters Prog/Analyst II C & T Phone: (502)588-5626 Dry yeast question: Could dry yeast be re-constituted in plain water and then add up to 5 or 6% of alcohol to kill bacterial and (hopefully not alcohol resistant) wild/mutant yeast? If one added a hop pellet or two to an ounce of 100 proof (50%) vodka, would that make the some hop oils water soluble? The vodka/hops mixture could then be added to a pint of re-constituted yeast-water. Brewing disasters: I was using the Charlie P. 3/8 diameter blowoff system in a two room apartment and after a couple of batches my luck ran out. Of course the hop bits clogged the blowoff tube. Fortunately I had shoved the carboy in a corner behind one of those poppasson <-sp? (looks like a satellite dish) chairs. There were dried hop bits all over that corner of the room. Lucky for me the hop bits (not to be confused with naughty bits - for you Flying Circus fans) washed off the walls and the ceiling was one of those bumpy ones that a can of white spray paint took care of. the big round pad from the chair became a dog pad for a friend's pet. The carpet required Mr Stanley Steamer's attention. Also I had set bamboo chair frame outside and the ants cleaned it for me :-) The second disaster was terrible! A new girlfriend came over for dinner and was quite impressed with my homebrew until she opened her second bottle. It was a beer geyser and blew foam all over her sun dress because she tried to close the swingtop cap and ended up directing the spray at herself. I, being a southern gentleman, helped her out of her wet sticky clothes and into the shower ;-) Like I said, it was a horrible experience. Return to table of contents
Date: Fri, 4 Sep 92 10:15:35 CDT From: pmiller at mmm.com Subject: To stir or not to stir... Hi everyone, I tried mailing the following question to Micah Millspaw (c/o Bob Jones) but it bounced. I've decided to post it to the HBD because I think it would be of general interest. Before I get to the question though... 1) I'm going to be including some information that I got from Micah in an e-mail message. If I'm breaking some cardinal netiquette rule about including information from a private e-mail in a public posting then I'll take my lumps and apologize. In my defense, I want to point out that I have good intentions (I'm trying to clarify a point, not criticize) and that most of this information has been posted to the HBD anyway and it wouldn't take a rocket scientist to deduce the rest... 2) If, after reading this post, you have strong opinions about Micah's mashing technique, you may want to verify that I've described his procedure accurately _before_ you post your scathing critique. Humble pie tastes terrible... Those disclaimers out of the way, on to the questions (finally!): Micah uses an underlet system for his mash which he described to me like so: Underlet tubing ---> | [ | ] [ | ] <--- Mash tun [ | ] [ | ] [ | ] [==|==========] <--- False bottom [__|__________] Micah has said that he adds hot water in different amounts to achieve a step infusion mash. He's also pointed out the importance of not stirring the mash (I think he quote George Fix here as saying that a lot of real breweries get into trouble by stirring their mash needlessly or something along those lines.) OK, question #1: Why is stirring the mash unacceptable? Miller's book (Dave's -- I haven't written one yet ;-) describes in excruciating detail just how to stir the mash while heating the pot on the stove to boost temperatures and it's pretty obvious that Jack's EasyMash system would require stirring, too. Now, the thought that comes to mind is that after a certain point, (e.g., 5 minutes before you begin sparging) stirring may disturb the grains and put a lot of flour into suspension. It makes sense that you may not want to mess around in the mash just before you try to establish the grain bed. But certainly you have to stir mash when you first mash-in, right? So at what point should you stop mucking around in the mash or am I completely missing the point? Question #2: I did some back of the envelope calculations (Quick! Can anybody guess what my undergraduate major was?! ;-) and I figured that for 8 lbs of grain and 8 quarts of water at 155 F, I'd need to add about 5 quarts of boiling water to bring the mash to 170 F for sparging. If I don't stir the mash, won't the hot water extract tannins from the husks that it contacts? Or does the heat diffuse quickly enough that this isn't a problem? Or, should I be using more water at a lower temperature to bring the mash to 170 F? How thin can you get the mash before you run into problems? Question #3: Assuming that stirring the mash is bad, why use an underlet system to add the hot water to the bottom of the mash (rather than, say, dumping the hot water on the top of the mash)? Is it because the grains are heavier than the water and therefore water that's poured on top of the grains just sits on top whereas water that's added to the bottom of the mash ends up percolating through the grains from the bottom up? Please, please, somebody straighten this out for me. I'm hopelessly confused. Thanks!

Then it is said >that shaking beer (before bottling) is bad--leads to oxidation >which taste buds don't like. So what is the difference in the >two settings? Why is unfermented cooled wort not as susceptible >to oxidation? The difference is in what the yeast are about to do. In the former case the yeast are about to go into a massive, aerobic growth spurt, consuming any oxygen they happen to come across. You want to give them lots of it to come across. In the latter case, the yeast are going to quickly consume the relatively small amount of priming sugar you add and then settle out; they'll use up some oxygen doing this, but they're not guaranteed to use it all, especially if it get's vigorously aerated. I actually feel that the "Conventional Wisdom" overstates the risk of oxidation at priming, but I don't want to risk my beer with experimentation and it's not too difficult to avoid aeration during priming. There's no question, however, that vigorous aeration helps the yeast get off to a good start after pitching. Jon Return to table of contents
Date: Fri, 4 Sep 1992 08:21:25 -0700 (PDT) From: Paul dArmond <paulf at henson.cc.wwu.edu> Subject: Specific gravity of hot stuff Bryan Gros will have some very heavy christmas beer. SG will always read lower when things are hotter. This is due to the fact that things expand when hot. More volume, same mass = less density. This size/temperature relationship is linear, as long as you don't have a solid/liqid/gas phase change. Charlie Papazian on p.26 of The Complete Joy of Homebrewing (1984) says that SG drops .002-.003 for each 10 degrees F above 60F. My hydrometer has a correction factor printed on it. This should be close enough for horseshoes and handgrenades. FWIW the beer I brewed Wedsday had an apparent SG of ~1.030 at 200F and a real SG of 1.051 at 60F. The coefficient of expansion may vary with the amount of sugars in solution, so it wouldn't hurt to check this out. Does anyone have a table of coefficients of expansion for worts of different gravities? Since gravities vary by 100% (more or less) this could have a substancial effect, or maybe not....

Date: Fri, 4 Sep 1992 08:43:30 -0700 (PDT) From: Paul dArmond <paulf at henson.cc.wwu.edu> Subject: Sparge times and extraction There has been some discussion of the relation between sparge time and yield. This week I did two test batches to calibrate the alpha % of my recent hop harvest. I made two identical batches, same grain, same grind, same everything, except the sparge times. I use a Gott cylindrical cooler with a vegetable steamer and mesh "press bag" to hold the grains. For batch B, I would drain ~.5 gal from the cooler, add more sparge water, then wait five minutes. Batch A B Sparge time 15 min. 45 min. Gallons in carboy 4.5 4.75 SG 1.045 1.051 As you can se, there was better yield from the slower sparge. In both cases, the grains had no sweet taste afterwards. I think that 15 minutes is too fast, and that you can go too fast or too slow. It is going to require more experiments to settle the issue conclusively, but I'll relax and take a break while sparging in the future. ====================================================================== Nothing Fancy Test Batch Ale 8# Munton and Fison pale ale malt .25# 40L Crystal malt mash with 2 gal at 152F for 90 min.

When I was packing my recent hop harvest I kept sheets of newsprint under the drying screens to catch the yellow resin that falls off the hops during handling. I now have a vacuum sealed bag with 1/2 ounce of the orange lupulin resin powder. I would be very interested in isomerizing this for post-fermentation bittering (repairing underhopped beer.) Does anyone have an article or reference on how this is done? All I know is that there are two processes: one uses sodium or potassium hydroxide, is quick and can overconvert into non-bitter isomers; the other uses sodium carbonate and is slower and less likely to damage the bittering. Any help would be greatly appreciated. Paul de Armond Return to table of contents

The earlier equation was based on data for 50F-to-105F. Since the equation was from a polynomial fit, it should not be trusted for predicting SG outside this temperature range. The data below was obtained using the "Handbook of Chemistry and Physics (CRC)", and is valid for a temperature range between 0 and 212F.

Date: Fri, 4 Sep 1992 10:00:18 -0800 From: eurquhar at sfu.ca Subject: For the adventurous: Chicha, corn beer of the Andes First, before you even think of planting corn from what plant quarantine would call a "briefcase introduction" consider the disease epidemic (blight, root rot, virus etc.) which would result from infected corn and the huge losses which would result to the American corn crop. Second, I found a recipe and method for chicha recently in "The Art of South American Cooking" by Felipe Rojas-Lomabardi (excellent chef and native Peruvian) published recently by Harper Collins 1991 (ISBN 0-06-016425-5). Chicha de Jora I pound jora (germinated and then sun dried whole corn, sort of like corn malt) 8 allspice berries or cloves 2 cups dense packed dark brown sugar Lemon wedges for service (1 tsp. dried Yeast for the less adventurous, use your favourite) 1. Grind jora until partially crushed. 2. Put all ingredients except sugar in stainless steel pot with 8 qts. cold water. Stir and soak for 1 hour. 3. Place over med. heat and bring to the boil. Lower heat and simmer gently for 4 1/2 hours. Stir regularily to keep from sticking. If a lot of liquid evaporates add some more water. You want 3 to 4 qts total mixture at the end. 4. Remove and let sit undisturbed for 1 hour. 5. Strain mixture using a stainless steel strainer into glass container through a double layer of good cheesecloth. Twist the separated mass to extract all the liquid and discard. Add sugar and DON'T STIR. 6. Cover with a piece of cloth. Pitch yeast into mixture here. 7. Let sit in dark draft free warm spot for 5-8 days. If all goes well it will ferment. The longer it sits the thicker and more potent it gets. Sounds like the andean version of lambic. JORA (corn malt) the author said that the preferred type in ecuador is from yellow corn where in Peru both yellow and purple corn are used. Soak whole yellow corn 1-2 days in cool water. Line a baking tray with several sheets of paper and cover with a double layer of cheesecloth. Spray with water until all is soaked. Drain water and then cover with double cheesecloth. Keep moist but not wet until corn is sprouted about 8-10 days (sounds like an awfully long time so use your best judgement). Dry in sun until thoroughly dry, several hot days but take in at night. Will keep indefinetely in dark, cool and dry place in airtight container. Well gang there it is. Haven't made it as I just got the book out of the library which by the way itself is fantastic. I'm going to give it a try someday but first some corn malt.

Date: Fri, 4 Sep 1992 10:00:34 -0800 From: eurquhar at sfu.ca Subject: Yeast culturing The method we use to sterilize instruments for subculturing is to dip them in 95% ethyl alcohol(for research it's tax free) but methyl alcohol will work and then burn off the alcohol in a bunsen flame. Dip as much of the instrument as possible into the alcohol. Do this a couple of times and believe me their sterile. Then touch the hot loop or probe to the new sterile plate or a clear spot on your culture plate to cool it. If the culture has no contamination this should cause no problem as generally only pure cultures are used. It is common practise to roll ends of test-tubes and flasks through the flame slowly to dry them off and kill any bacteria which may of fallen on the neck.

Date: Fri, 4 Sep 92 8:30:44 EDT From: chuck at synchro.com (Chuck Cox) Subject: Electric Corona In order to take full advantage of the AcoustiMash (the false-bottoms are being laser-cut now), I am going to electrify my Corona grain mill. I've got a big, powerful variable speed drill that will be perfect. I re-read the article in the all-grain issue of Zymurgy, but that is really only a half-design since it just leaves the electric drill sticking out in space. I'd like a self-supporting system, so I don't have to hold the drill the whole time. I'm considering using a second sawhorse, or perhaps doing something creative with a 90 degree drive. I'd appreciate pointers to more useful articles, or ideas that you have seen work. Once the mill is electified, how fast can I run it before something bad happens? What are the symptoms of a too-fast grind? On an only slightly related note: Has anyone ever overloaded a cajun cooker type gas burner? I've got one of the smaller ones. I've had no problem with 10 gallon batches, but a 15 gallon keg might be too much. I'm going to have some extensions welded on to hold the half-barrel kettle, and I'm wondering if I should reinforce the legs too, the three legs are made from what looks like 1/2" iron bar. - -- Chuck Cox <chuck at synchro.com> In de hemel is geen bier, daarom drinken wij het hier.

Would not the fact that a blanket of CO2 over the beer make it an anerobic environment? ................ Well, I just had my first taste of meade and I did it the easy way.. I drank someone else's. One of the neat things about this forum is the ease with which one can make friends (and deals) with people with a common interest. I recently swapped a video and a bottle of beer and a small nip of 1971 brandy with John Wyllie for two bottles of his pampered meade. He sent me a bottle each of cyser and methaglin. The methaglin is too young to try yet but the cyser was from Nov 91 so we popped the cork with a Chineese dinner. I, of course am not a certified judge, nor do I have any ribbons so I wouldn't dare use any of those fancy words. I will just describe the experience in words us Joe sixpaxes understand. The cyser was crystal clear and the cork popped right out with little help. It was bubbly and efervescent like a fine champagne. Problably the most interesting thing about it was the aroma. I have never smelled a drink quite like this. It was like walking through a meadow in full bloom. Not the pukey sweet smell when you jam your nose into a carnation but sort of like a funeral parlor at 20 paces. We were looking for something that tasted like honey and it did not, so therein lay the only disappointment. What it did taste like, escapes my humble vocabulary but it was dry and mild and resembled a good champagne. The first glass went well with the food. As the alcohol content was higher than I care for, I drank only one glass. My wife finished the bottle and dragged me off to the bedroom. As an aphrodisiac, it gets the gold. In summing up, I would call it an amazing champagne taste-alike considering that it contains no grapes. I used to make champagne with grape juice concentrates and was only moderately satisfied with the results. This cyser is indistinguishable from good champagne. I doubt that the gods on Olympus drank this stuff but I now have a better idea of what is was they did drink. Neat stuff, John. Thanks for sharing it with us. js Return to table of contents

I start the whirlpool with a long-handled spoon, trying not to splash the wort anymore than necessary. When I draw the wort off, I get a dramatic cone of hops, especially if I use (as I usually do) pellets. The trick, I think, is the take-up attachment for the wortchiller siphon hose. I have a copper tube of the same diameter which runs around the inner circumference of the kettle. The bottom of the loop (the part touching the bottom of the kettle) has scores of teeny-tiny holes drilled in it (I used the smallest bit I could get for my Dremel Mototool drill). Needless to say, the end of the copper tube has been hammered closed, so the wort has to be drawn through the little holes. These holes are small enough that loose hops never clog them, and if the whirlpool has been done properly, pelletized hops almost never do. _Sometimes_, it's necessary to give it a gentle jiggle if the outflow has dropped noticeably -- this usually clears the holes completely. I tend to use pelletized hops because they sop up less wort. - --Jeff Frane Return to table of contents

The part that sifted out was called " smeddum "--which word Burns takes occasion to use metaphorically. It was kneaded up into tiny bannocks, baked on a griddle and eaten. If when baked the smeddum inside the crust was in taste and appearance like a thick dark syrup, the malt was good and strong. If not syrupy, the malt was poor. These smeddum bannocks were rather tasty, and the entire household judged it necessary to pronounce on the malt. . . .

Call me Stone Skin.......JDW > Indoctrinated? If you mean how do they know the rules, they are displayed at the top of each issue of the Brewer's Forum. I used to take harshness with a grain of (Epsom) salt, but that was in netnews, not in this private digest that I co-founded. When beginners start to fear posting -- even I began to second-guess my questions, it's time to do something about it. I've been a contributor since the HBDs inception in 1987 and the mood was always friendly -- look at some of the back issues. No one had an axe to grind or a pet peave over which to stab someone in the back. We were all friends, even when the numbers got up to 4000 digest members. Then came Jack Schmiddling. He introduced hatred and intolerance to the HBD and caused the mood of the digest to change. Suddenly, posters who were silently sitting in the wings listening about beer, started jumping in with "lame" comments. Any idiot with one or two poorly-made beers can make someone feel bad (and themselves "important") by calling them "lame" or humiliating them. That's not the spirit that I want to be a part of. If you'll notice, I haven't posted anything to the HBD in a while -- instead I send private mail -- it gets to the person faster and they won't get bowled -over if in tomorrow's digest someone calls them lame. It's much harder to answer a simple beginner's question without making them feel stupid. I've always gone out of my way to answer "stupid" questions in a way that doesn't make the person feel dumb. I'll say "Oh, that's what I thought too, but then I read that..." Some will not take the effort to be nice. They may be too busy or just lazy, but I can't blame them. There are people, though, who try to make themselves self-important at the cost of others. Those people should have their fingernails pulled out in slow motion. Sorry. I got carried away. The bottom line is, that its not that hard to be nice, and its *especially* important to be nice to beginners. I recall when I didn't know anything and in fact read Charlie's book twice before I had the courage to try my first batch, even though all the ingredients and equipment was sitting there ready to go. If someone blasted my beer or technique back then, I may not have brewed a second batch. I don't want that to happen to anyone -- the more homebrewer's the happier. Al. P.S. I feel that these are very important points and that my feelings on this subject should be known by the HBD membership, so I'm Cc'ing the HBD. Return to table of contents

Well, I've got another two things for the collective wisdom to comment on... 1 - I've just tried my first keg batch - a light ale of 6.6lbs extract, 1.5 lbs misc. grains, etc. When I first tapped it, almost all that came out was foam. This quickly subsided into beer with very little carbonation in it. The head was _great_! But I want some more carbonation. It sat for two weeks at room temp; I thought that should be enuf. Anyway, it tastes fine, except for the lack of co2. Now, I've increased the pressure up to 30psi and shook it vigorously a few times a day, and its getting more carbonation in it (more yeast bite too :-). Any suggestions on how to avoid under- carbonating a keg in the future? 2 - I always make ales, but bought larger yeast by mistake the other day. What the hell... I'll give it a go. I suppose this brew should be something like Anchor Steam (yeah, in my wildest dreams!). The stuff fermented very actively in my primary; emitting a foul sulphur smell. When I racked it to the secondary 5 days later, all activity has seemed to stop. The ferm. lock has not bubbled and shows no signs of a pressure difference. Any words re the care of larger yeasts for an ale brewer? As always, thanks for the input -Chris Estes- Return to table of contents
Date: Sat, 5 Sep 92 09:15:39 -0400 From: parsons1 at husc.harvard.edu Subject: My first batch of lager beer Greetings, all, I have been brewing all-grain ales for almost three years now. The recent blessing manifested in a FREE REFRIGERATOR gives me, at long last, the capacity to brew lager beers. There is one problem, though, that of course I have never brewed lagers before. I read Miller's chapters on lager, but, as usual, those made me feel more miserable and depressed than able to brew. Thus, I beseech the lager brewers of this community to offer me some advice. First, though, let me present my first recipe and brewing schedule: For 5 gal. of dopplebock: 6 lbs Dutch dried extract 4 lbs Pilsener malt 2 lbs Munich malt 1 lb German crystal 1 lb Chocolate 1 1/2 oz Hallertau (60) 3/4 oz Hallertau (30) 1/2 oz Hallertau (15) 1/4 oz Hallertau (5) Wyeast bavarian lager yeast 8 qts water to strike heat 140F protein rest at 122 for 30 min starch conversion 1/2 hr at 153, then 1/2 hr at 149 mash out at 169 sparge with 4 gals. Boil 60 min I plan to have a primary fermentation in a 6-gal carboy, then a secondary in a 5-gal carboy fitted with a Brewcap, and then to bottle. My questions are, what temperatures should I shoot for for the various steps in fermentation? Should I raise the temp a little after secondary fermentation to help eliminate diacetyl (according to Miller's suggestion)? Is it even necessary to execute primary fermentation below basement temp (65 F)? Will my bottles get primed at 55F, or will the yeast just go to sleep? I should be overjoyed at any help. If you have a response which you feel is too pedantic for posting, please send it anyway to me. Thank you!

In May, Elmhurst switched over to Lake Michigan water. Prior to that the water source was ground wells. The ground wells had high levels of Radium. And yes, thats Radium, not Radon. I live in the town next to Elmhurst and we had the same problems. We too switched over to Lake Michigan water but up to that point we received the following disclaimer every three months: " . . . The Village of Villa Park Public Water Supply wishes to advise its customers that the Maximum Allowable Concentration (the maximum amount allowed in drinking water) for radium has been exceeded in samples collected during the past year. The MAC for radium as designated by the Illinois Pollution Control Board is 5 pico curies per liter of water. Quarterly samples taken over the past year indicate the average level to be 8 pico curies per liter. A portion of the radium which is ingested remains in the bone. The radiation which is given off from the radium, because of its high energy, causes damage to the surrounding tissue. A dose of SpCi/l may result in the development of bone cancer in a very small portion of the population . . ." Beer anyone? This spring Lake Michigan water came to Dupage county so this is all a moot point. Needless to say, I'm REAL happy about getting Lake water but I'll certainly miss those glowing reviews from the beer judges. One added benefit is that Lake Michigan water is great for brewing. All the right ions in the proper concentration. Now if I can only figure out how to get rid of the high levels of PCB's. chris "Radium Ale" campanelli Return to table of contents
