No, not fermenting your folks, rather you are a parent! Its long, so I'll send it on two Digests. If you aren't a parent with parental duties, you might find this interesting just because of the brewing 'technique.' PART 1: I had Big Plans to squeeze in a brew day, my first one of the year (!), this past weekend. "Hurrah," I thought! The handy-dandy yeast cake from the last batch was a question mark, given the month it had sat since being fed, so I decanted, tasted the starter beer, and did a water wash. Tasted OK, looked OK...let's Brew! Trouble: my (non-fermenting) Mom and Dad were having an overdue birthday party for my bro Scott...on Saturday evening! With Brew Day in limbo, I immediately thought, "Overnight Mash!" Dandy! Soooo, Friday after work, after feeding and playing with my 1 & 1/2 year old, after putting her down to bed, this journey began. Rather, it was a sojourn, I'd say! Weighed out the grain bill for this yummy Oatmeal Stout I'd been hoping to get to...using a wopping 20% oatmeal (trouble ahead???)...then I ground the 20+ pounds of grain, fired up the Bradley Basement Brewery, and, "Let the Strike Begin!" After a lengthy anti-glutin rest, I headed up to a target 156F mash. Oops...make that a 160F mash!!!! And some scorching too...converted kegs don't heat as evenly as my aluminum does! Wrapped that mash up with some bubbled foil insulation, and at Midnight, Hit the Hay!!! "Joy of joys! I'm brewing while I sleep!" Then it was 7AM, and the kid was waking up. Mom headed off for her weekly Sanity Break (tennis) at 8AM, and me and the kid played and romped around, all the while, "I'm brewin'!" After a quick shower, Mom packs up kid's clothes and they head off on the 1HR trek to my parent's place. The Plan: I'd finish up the brewing and just meet them there, before the dinner party. OK then, its 10:45AM, and I'm back into the Brewery! "Joy!" The mash is at only 120F...hmmm, better insulation next time. Smells a little vegetative, but a little souring is OK in a stout:) Heated that puppy back to mash-out at 175F, not so much scorching in this thinner mash...must have been a few m Eq of enzymes left. Then, the Nearly-Never-Ending Lauter began. Hooked my pump up to the outlet, recirculating back into the keg, and let my sweet wort clarify! And clarify, and clarify! "Wow, this flow rate is ridiculously slow!" Sooooo, I headed out and talked with one of the neighbors for a bit. Came back, still kinda cloudy. "He-dbl-toothpicks" with it: let's collect that sparge! Its now 2pm. Hmmm. I have to leave by 5pm? Slooooooooow (not stuck) sparge. At least I had plenty of time to get my sparge water heated! And to pack for the overnight at my parents. And to make up a re-energizing yeast starter. And to go out and install a subwoofer in my truck. Seriously. With the ending gravity of 1.010 reached, I had 13 gallons of sweet wort collected, but it was 5PM: time to leave. "What the he-'', might as well make this a three-day brewing session!" Sooooo, more insulation wrapped up my two collection pots, and I was Off!.........to be continued.... Dave in Indy Home of the 3-B Brewery, (v.) Ltd. Return to table of contents

Is it salvagable? if it was fermenting hard, there would have been a continuous evolution of co2 out the top of the carboy. airborne microbes outside would have had a tougher time than usual getting into the carboy, due to this "outflow" of gas (which they, by the way, cannot survive in if they are aerobes). lots of people ferment in open fermentors. i guess the big question is: what's in your closet? as long as there's not a lot of raw sewage or other highly desirable (to bacteria/yeast/etc.) substances, your beer will probably be fine. - ---------------------------------------------------------------------------- mike marshburn wrote: > I remember reading about souring a beer with lactic acid, but I >can't seem to find a recipe with any amounts.

If any of you have done this I >would really like to hear from you as to the amount you used and what >were the results. i have no experience with souring a beer after it's fermented, but...... you can easily make a sour mash beer by mashing in 10% or so of the grist bill a few days before you brew. take it through a saccharification rest, and then lower the temp. to around 120 or so, toss in a handful of uncrushed pale malt, stir, press any air entrained in the mash out (if necessary), cover the mash tightly with plastic wrap or something else to minimize contact with the air, and insulate. after 24 to 72 hours, the bacteria lactobacillus delbrueckii will have created enough lactic acid to give your beer a definite lactic flavor contribution. this sour mash will yank your mash pH down, due to its acidity. it's optimal if you can keep the mash from falling below about 105 degrees fahrenheit. if it gets much lower than this for a long enough time, there's a risk that other microbes will have significant activity and start spoiling the mash. despite this, i've had good success with the method using a regular thermos-type canister wrapped in a blanket. greg noonan wrote a good article on sour mashing a few years ago in zymurgy. btw, 10% of the grist bill will have a very noticeable impact at sour mash durations of 48 to 72 hours. as the beer matures, particularly if lagering, the sour flavor mellows and blends with the other flavor components to make a smooth profile. weizenbiers stand up to this amount (10%) pretty well. in my experience a pilsner benefits from no more than 5%; this is all subjective, though. - --------------------------------------------------------------------------- michael newman wrote: >The Ld is in the fermenter doing its stuff.

Date: Tue, 4 Mar 1997 15:59:00 -0500 From: "Reed,Randy" <rreed at foxboro.com> Subject: summary of temperature control advice (Randy Reed) I recently posted that during the coldest part of the year my basement temperature drops below optimal primary ferment temperatures. I asked the collective for advice for keeping the fermenters WARM enough inside my temperature controlled fermentation fridge. The fridge has a controller for the fridge to go on if too warm, but nothing to warm it if too cool. Replies from many people came in. Thanks to all. They were all practical and some were very simple. I like simple and will start with that. 1) Wire the existing fridge bulb to stay on, but be sure to cover the carboys or cover the bulb so that light does not effect the wort. (This approach is cheap and will answer, once and for all, the question: "Does the refrigerator light stay on when I close the door?" ;^) 2) Add a separate light of low wattage. Experiment with the wattage until you find one that warms enough, but does not make the fridge cycle on too often. An additional thermostat can be wired to this light so that it only comes on when the temp goes too low. Place the light in a large coffee can to shield the wort from the light. Punch holes in the can for ventilation. 3) Place the fermenters in a bucket or bin of water. Use an aquarium heater (at least 100 watts) with built in temperature scale (about $25) to warm the water to the desired temperature. (This was in the "Z" magazine, you know, the one from that non-profit organization) A number of replies raved about this. One person mentioned putting a tiny amount of bleach in the water to control the bacteria, as long as you are using closed fermentation. 4) Other thoughtful replies included using a radiant heating panel and a terrarium warming stone normally used to warm reptiles, as well as placing a couple of gallons of warm water in the fridge each morning to keep things warmer. Thanks to all for the great replies. The water bath has advantages. Once you buy the aquarium heater, you can primary in the water bin and your fridge is free for other (lager) things. There is no inherent problem with light. Also, you do not have your fridge working to keep the bulb you placed in it from heating too much. This reminds me of a joke by comedian Stephen Wright. To paraphrase his deadpan humor, "I got a humidifier and a dehumidifier for my birthday. I put them both in the closet and let them battle it out."

Our competition is for you. The Fourth Annual Great Arizona Beerfest Homebrew Competition is scheduled for April 4, 5 & 6. All AHA categories will be accepted, including meads and ciders. Every entry will be judged by at least one BJCP qualified judge. We are expecting over 300 entries in this years' event, so the competition will be stiff. Besides good feedback prior to the Nationals, the 1st, 2nd, &3rd place finishers will receive medals and a small gift. The BOS will receive a handsome trophy and a $100.00 gift certificate from The Homebrewery in Sierra Vista, AZ ( yes, they do mail order). In addition, a Brewers' Choice award will be awarded to the most commercially viable entry in the BOS round as judged by a select group of local commercial brewers. The winner will receive the right to brew the winner at a local brewpub. So don't delay. Direct your requests for Entry forms and guidelines to: Rick Drake 5325 W.

Date: Wed, 05 Mar 1997 14:08:16 +0000 (GMT) From: DAVE BRADLEY IC742 6-7932 <BRADLEY_DAVID_A at Lilly.com> Subject: Dave's Family Brewing, Part 2 PART 2 of Dave's "funny but true" story about squeezing in brewing to an otherwise busy Family Life....sorry if the first part bored you, but at least you can Page Down through this final installation! Continuing from where I left off, after the sparge.... With the ending gravity of 1.010 reached, I had 13 gallons of sweet wort collected, but it was 5PM. "What the he-'', might as well make this a three day brewing session!" Sooooo, more insulation wrapped up my two collection pots, and I was Off! Dinner, party, fun w/kid. When I got to my parents' place, my brothers were in the kitchen formulating some froo-froo fruit-n-booze drink in the blender. So I grabbed a beer! NOW, its the third day. I hang out with the family for a few hours, help feed/decorate the kid with lunch, chase her (my child) around, then head back to the Brewery. Its 3PM. Hmmm, the sweet wort is a bacteria-friendly 95F. Smells a little more 'unusual' and tastes, well kinda like a sweet-n-sour soy sauce (c'mon, you wouldn't grimace so if you were cooking with it!!). Malty though;) Hey, that yeast starter is looking un-fermented! Oh well, maybe the yeast are shocked. I know I am. After cleaning out the keg form the mash, in went the wort. Heated up, boiled with the hops, added a can of Black Treacle just for kicks, sanitized the 15gal conical fermenter, tho' I'm not sure why, and all went well. Pumped the bitter wort up to the fermenter, spraying it for some O2'n. Pitched in the sluggish-but-going yeast starter, and cleaned out the equipment. Boom, its 9:30PM on Sunday night, a "beer" is forming in the fermenter, and I'm goin' to bed so I can really 'work' Monday. Monday 6AM, the yeast ain't done much, and I drain off a bit of trub. Monday 6PM, ditto plus a bit, and I read the gravity: 1.053 for a whopping 14% attenuation. Why should I care if another step of this "beer" is going abnormally? OK, let's stir this puppy up, maybe the yeast didn't mix well..... Temp is fine at 62F, right were I left it from chilling. Tuesday (today) 6AM....YEEEEEHAAAAH! There's a 3" krausen over this stuff! Its finally going....hurrah!!! So there you go, I hope you found as much humor in this as I DO, now. This most certainly will be the best beer I've ever brewed, its destiny. Nothing went as planned, every step was slow, some equipment troubles. But I DID brew, my wife and kid had a good weekend where Daddy didn't just disappear into the basement for 12 hours, and if nothing else, I'll have 10+ gallons of awesome brat broiling beer. That ain't bad!!!! I'll send out some follow-up, just in case this turns out to be some fantastic Belgian-esque beer :) Maybe I can interest the Boston Brewing Co!!

Date: Wed, 5 Mar 1997 09:47:58 -0500 From: Steve Zabarnick <steve at snake.appl.wpafb.af.mil> Subject: Filemaker Pro Brewing Software Just when you thought there was enough brewing software available on the net... I am making available, for free, my Filemaker Pro 3.0 based brewing software. This is a Filemaker Pro database which can be used to formulate recipes and keep a log of your brew sessions. Gravity, color, and bitterness units are calculated and can be compared with style guidelines. Hop bitterness is calculated using the utilization numbers of Glenn Tinseth, and color is calculated using the color correction of Martin Manning. This is available in both Macintosh (binhex/stuffit) format and Win95 (zip) format (Win95 version is untested; let me know if it works!). Long filenames are used so it will not work with Win3.1.

My last batch was an Ale made with 16 Lbs. of grain for a 10 gallon batch. OG was 1.043 I transfer my wort from the kettle to the fermenter with a 1 gallon pail and do my best to splash it into the tank. When full I aireate for about 30 min. with a acquarium pump. (Yeast added after 2 gal. in tank). The beer fermented at 58-60F for 3 days and was done! Gravity 1.011, I let it sit one more day gravity still 1.011 I could be drinking this one by the weekend! Anyway I like this yeast, a little fruity but not overly. I thought about rousing the yeast but did the density reading first and was happy with the finish point. I'd be glad to hear any comments (except about my spelling) Rick Pauly Charlottesville,VA Return to table of contents

Date: Wed, 5 Mar 1997 11:25:01 -0500 From: "David R. Burley" <Dave_Burley at compuserve.com> Subject: Boil volume Brewsters: Tim Fields asks if it makes any difference when he adds water to his wort. C. Papazian has an effciciency of hops extraction versus wort concentration in his book. Message is, the higher the wort concentration the poorer the efficiency of hop bitterness extraction. Your wort should be as dilute as you can make it and still end up with the desired volume after the boil. As far as it being difficult to get a full volume of wort in the boil with your setup, I have to believe you are carrying the idea of a full boil to an extreme. The term rolling boil is more like what is desired, since all you want is the hops to be constantly agitated. I boil about 6.5 gallons of wort at the beginning in two 4 gallon kettles with a watchful eye for the first few minutes and I usually end up with about 4.5 to 5 gallons at the end of an hour with the lids partially covering the boil most of the time after the initial boilup. - ------------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3202 at compuserve.com Voice e-mail OK Return to table of contents

It was never the intention of the AHA to own the recipe. The AHA was trying to provide copyright protection on the recipe for the brewer and the NHC. We have recently had situations where a brewer's recipe is re-printed without contacting THE BREWER or the NHC for permission and then no credit is given to either. We will immediately strike that sentence from the Web page and provide all entrants a letter stipulating their ownership of their recipe. As far as Boston Beer Company's Longshot Competition, we haven't received any confirmation about what their plans are so I can't enlighten you yet. We'll post as soon as something happens.

I sought out and bought silicone tubing after ruining two batches (I'm a slow learner) by siphoning hot wort through new vinyl tubing. It imparted a very obvious and disgusting plastic flavor to the beer. It is clear (well, slightly cloudy), and has a rated working temperature range up to about 400F, so I can even autoclave it or bake it in the oven to sterilize it, if I so desire. Unfortunately, in small quantities, it's quite expensive ($2-$4/ft). I engineered a bulk buy via the HBD and ended up getting 150 feet (in 50 ft units) at a total cost, including reshipping, of about $1.25/ft. I love it. Return to table of contents

If I wanted to make say 20 gallons of beer, would I need to start the >boil with 24 ? > >My quess is the bigger the vessel the more evaporation occurs.. MY best guess is that main factors influencing the evaporation rate are the output rating of the heat source, transfer efficiency of the heat to the wort and heat loss from the tank. Surface area of the wort surface and air flow over the wort surface will affect the evaporation rate a little bit, but I suspect these will be relatively minor effects compared to those listed above. I emailed Mike asking about the output of his burner, and he replied: >my heat source will be a twin 170K btu ring burner, so total BTUs will be 340K Assumptions: burners running full speed, efficient transfer of heat from the burner to the wort, no heat loss from the boiler other than via evaporation. The resulting number will be an upper limit - reducing the output, inefficient transfer of heat or heat loss would all reduce the evaporation rate. We're also assuming pure water; concentrated wort will probably evaporate more slowly. Water has a heat of vaporization of 9.72 kcal/mol. Converting from kcal to BTU, then moles H2O to gallons, I get 8100 BTU needed to evaporate 1 gallon. Burner rating gal/hour evaporated Comment 35 kBTU 4.3 my burner, for reality check 170 kBTU 21 one of your burners 340 kBTU 42 both of your burners Reality check: on 6.5 gallon boils using my 35 kBTU burner, after getting up to boiling temperature, I throttle back to get an evaporation rate of about 1 gallon / hour. I have no way of measuring just how far back I'm throttling it, but my best guess is that I'm at 50% output. That in turn suggests about a 50% efficiency for using burner output to evaporate water. If these calculations are reasonable, they suggest that 340 kBTU is overkill for a 20 gallon batch! The high output will help you get to the boiling point faster, but then I'd cut it WAY back.

Dave Burley mentioned: There are some mechanical starters on the market, but I have never tried them. - -------------------------------------------- I use Phil's Psiphon Starter, it works great! It is a simple little one-way ball valve that attaches to the end of your racking cane. You can start your siphon by simply jacking the cane up and down with the low end in your beer/wort OR (so I found with my most recent batch) you can take little "tokes" ;) on the low end of your hose -- each little toke you take on the end of the hose will draw a little more beer/wort into the siphon, and it will NOT fall back, 'cause of the nifty little gadget at the bottom of the racking cane. I would think that this would afford quite a bit more of a safety factor when siphoning hot wort. Cool, huh? 8) - --Kris Jacobs - --Kalamazoo, MI Return to table of contents

If this tap water pH persists after boiling and cooling to 70F >and you still suspect it is a yeast killer, then just sprinkle the yeast Dave is absolutely right about not stirring till the yeast has rehydrated. You are verly likely to kill *zillions* of yeast if you smoosh them around with a spoon while they are all stuck together in a glob (technical terms, email me for translations ;^). What alarmed me was Dave's implication (possibly accidental) that 70F water should be used for rehydration. In a newsletter published by Lallemand (a very large yeast mfg), they said that dry yeast should be rehydrated in 90 to 110F water. I suggest that the water be boiled, poured off the sedimented calcium carbonate (that's probably where the really high pH comes from) and cooled only to that 90-110F range. There's more info (although no mention of rehydration temperature, alas, other than saying that you don't want to dump yeast that has been rehydrating at 104F into cool wort) on the Lallemand Web page: http://www.lallemand.com/ . See Jim's Fermentation Hints. Also, it's important to point out that water and not wort should be used for rehydration (mentioned on that web page). Al.

Our choice is between Gervin's lager yeast or Gervin's ale yeast. Vanilla or chocolate. On my last visit to the homebrew shop, they were out of lager yeast (pathetic bastards), so I used a yeast packet from a Cooper's Lager beer kit in my latest batch of pils. The results were, shall we say, explosive. I pitched the yeast before going to bed, and in the morning I found foam all over the floor. I pulled out the foam covered airlock only to get a bath of green hop residue all over my nice white shirt. It appears that Cooper's lager kits use a top-fermenting yeast, with an unusual hunger for pils wort. By the way, the Cooper's yeast was left over from a batch of Cooper's lager I made with two cans of Cooper's extract, 25 litres of water, and one package of yeast. (Beer stocks were running dangerously low and I didn't have a free weekend for grain brewing.) The resulting beer was double-hopped (an added bonus) and very tasty. I'm worried about the pils, however. Bruce Return to table of contents
Date: Wed, 5 Mar 1997 13:41:35 -0800 From: Mark Riley <mriley at netcom.com> Subject: Siphoning Technique Hello HBD, After seeing a couple posts that mentioned siphoning problems I thought I'd chime in with a simple technique I just recently figured out. In the past, I'd try to start a siphon (using a racking cane) but for some reason or another it wouldn't take and I'd have this gravity assisted column of beer/wort shooting back into the carboy which, of course, would bore a hole into the trub and basicly create a little cloud of the stuff that I had so patiently waited weeks to sediment out in the first place (grumble). Another problem I had was that once I had the siphon going there would inevitably be this air bubble (many inches long) located just after the curve in the racking cane - the AR part of me couldn't help but think that that bubble was unnecessarily aerating my finished beer (just great). So the first thing I did was lop off that curve in the racking cane - so now I have a racking *tube*. I used a sharp knife (watch the fingers) so the cut was clean and didn't have any scratches that bacteria might find a home in (AR, I know). I now affix my racking hose and use the curved piece of the racking cane as a mouthpiece so I don't contaminate the end of the hose with germs or whatever. Now, with the racking cane in a carboy (at kitchen counter height) and the mouthpiece in my mouth, I grasp the middle of the hose and elevate it above my head so that the hose forms an inverted "V" (shaped like a teepee). Ever so gently I suck on the mouthpiece (how would YOU phrase that? ;-) and allow the column of beer to rise to just below the apex of the inverted "V". In one fluid motion (no pun), I bring the hand grasping the hose down so that the hose now forms a right side up "V" (you want to open your mouth and release the suction as your hand reaches chest level, just hold the mouthpiece with your teeth.) If everything has gone well (and it always has for me), the hose is now full of beer and none has spilled out since your mouth is (or should be) above the level of the beer in the carboy. I can then liesurely affix a bottle filler or pinch the tube and stuff it in another carboy if I'm racking. Works every time and no air bubbles in the line! BTW, a neat trick to free up a hand when racking (or bottling) is to put a drilled stopper on the racking tube so that it holds the tip of the racking tube above the sediment in the bottom of the carboy. Of course, you need to drill another hole so air can get in (not as easy as it sounds). You also need to put a short stiff straw in the drilled out hole, otherwise, the stopper sorta reclaims the hole you just drilled. When using this method I always start with the carboy tilted with a book and the racking tube several inches above the sediment so none is sucked up - as I near the bottom I slow down the siphon by placing my finger over the air inlet and moving the racking tube closer to the sediment. Oh, I forgot to mention that I put a bend in the racking tube (by heating it) so it can reach the bottom corner of the carboy. I suppose this works sorta like the orange caps with two holes - just a little bit less expensive. Sorry for the length of this post (on what appears to be such a mundane topic), but I know there are those of you out there who grumble (like I did) when it comes time to siphon...

Don't know when the change occured, but probably several years ago. I suspect your yeast has mutated. This is quite likely under commercial propagation. The likelihood of this happening depends upon how often Wyeast re-inocculate their propagators with a fresh dose from the donor brewery. ******** Reply to "phil" #2366 Not too sure what your question is. If you wish to darken a beer that you have already brewed, you are going need to use an awful lot of chocolate malt to get it to Guinness colour (200EBC, app 196SRM). Guinness use 10% roast barley in their grist. The best bet I would think, would be to boil up some roast barley (13-14oz per US 5 gall) in a minimal amount of water and add this water to your cask. You can prime at the same time if you wish to. There is no need to mash either roast barley or black malt. Not much point in mashing choc malt either, although there is a bit of fermentable extract that can be obtained from it. If you are talking about brewing a different Guinness clone, then you need to get closer to the Guinness grist which is typically 10% roast barley, 20-30% flaked barley (depending on type of Guinness) the rest is 60-70% of something like mild ale malt or any relatively high protein malt. The higher protein malt will have more enzymes to attack the flaked barley, and a protein haze isn't going to matter in a beer that's jet black.
