---------------------------------------------------------------------- Date: Thu, 3 Dec 1998 15:29:46 -0600 From: Vachom <MVachow at newman.k12.la.us> Subject: Remembrance of Things Blatz In #2891 Donald muses on the high degree of interest in homebrewing CAPs in the Upper Midwest--namely Wisconsin and Michigan. Donald, I believe your theory to be true; you might even add this "you can take the boy out of Michigan. . ." tidbit to the positive evidence column. I've been away from my home state of Michigan for 13 years now, but my interest in brewing CAPs stems directly from Carling's sponsorhip of the Tigers (Ken Caminiti: "No thanks, I'd rather not make that extra 2 million a year."), the memory of long summer afternoons drinking beer with an old farmer, a strict Blatz man, after we'd put the hay up, silly undergrad pilgrimages to Frankenmuth, pitchers of Schlitz Dark at the Brown Jug in Ann Arbor. And in Wisconsin. . . .well, now you're talking about one of the few places in the country that has maintained strong regional affinities for locally brewed beers.

Date: 03 Dec 1998 17:18:12 -0500 From: Christophe Frey <cfrey at ford.com> Subject: AHA's 20th Anniversary to: post@hbd.org Charlie, so good of you to stop by and let us know about the AHA's 20th anniversary. I mean that. Much has been said about merits and drawbacks of the AHA, it's current leadership, direction and publication. But most agree that it has made significant contributions to both the creation of and the advancement of homebrewing. I have sat quietly on the sidelines when some have bemoaned an erroneous article or poorly stated fact. But the bottom line is: I like Zymurgy, the AHA homepage, enjoyed the hell out of the 1997 AHA convention in Cleveland (we spoke about my barley wine specialty). I also like Brewing Techniques, Brew Your Own, Malt Advocate. Let's face it. I enjoy just about anything that promotes this passionate hobby of mine. Now that I know that you can find your way onto the HBD, welcome, kick back and have a homebrew. Let me tell you that you have a good man in Brian Rezac. He is passionate and not afraid of taking on some constructive criticism. As one of the groups that took part in Big Brew 98, he has recently contacted us for input on Big Brew 99 (mark May 1st on your calendar). In fact, Rob Moline's10/20 recipe is so bitching, I am coincidental brewing it again this Saturday at a local homebrew shop (Brew & Grow) as a demo and the resulting brew will be served at the proprietors wedding next September.Now I can tell people about the 20th anniversary as well. Just thought I would add a friendly, reasoned voice in anticipation that there may be a few other views represented in tomorrow's HBD. Sincerely, Chris P.

It's too bad the 7000 people who quit the AHA in the last two years won't know about this historic event. I'm glad Charlie took time to write HBD and let us know about it. However, I wonder why it wasn't important enough to mention on their Beertown web site. I bet it was Zymurgy.

Probably the most complex beer I've tasted. If any you > get a chance to have some (assuming you like lambics), don't hesitate. I was also very excited to lay my hands on 3 bottles each of the Gueuze and the Kriek. Tried a Gueuze and was disappointed. Very little brett character. It did have an off flavor that was kind of a medicinal phenolic, bordering on metallic, that I found objectionable. Nice complex sourness with some acetic, but not as much as typical Cantillon. The store owner warned me about huge bottle-to-bottle variability, which I would have anticipated anyway, so we'll see what the other 5 bottles have to offer. Regarding hops, Matthew's plan sounds great. I have some '94 Mt. Hood that I obtained in late '96. I spread these in a 4" layer on sheets in my garage for several months (it's 50 lbs of hops). They've been loosely bagged at garage temps since then and they still have some good aroma. Cheesy came and went while they were on the floor. Now they smell a bit like hay. Be prepared to wait. A little baking can help you along too.

Date: Thu, 3 Dec 1998 22:10:55 -0500 From: "Jeff Hewit" <jhewit at erols.com> Subject: Is My Beer Ruined? I started brewing an ale a few weeks ago, using Yeast Culture Kit Co. American Ale, which I have used before with great results. OG was 1.052, fermentation temperature mid-60's. I racked it the secondary after 10 days - I would have liked to have done this sooner, but it's a busy time of year. SG at racking was only 1.020, so I figured/hoped that racking would rouse the yeast and get the gravity down a few more points. I tasted it at racking, and it was OK in spite of the slightly high SG. Activity resumed within a day. However, it's been in the secondary for almost two weeks, and it's still bubbling away - about a bubble/second or faster. This activity can't be from normal fermentation. I suspect yeast autolysis, but I've never experienced this before, so I'm not sure. I'm afraid to bottle with this much activity. Any suggestions. Should I bottle anyway, and hope I don't get any grenades? Should I just wait for as long as it takes to stop? I have been advised to bring the temperature down to the low 30's if possible to shock the yeast into submission - any comments on this? Or might I have a contamination or other problem that warrants tossing the batch? Any suggestions appreciated. Brew On! Jeff Hewit Midlothian, VA Return to table of contents

Gros" <gros at bigfoot.com> wrote: >Actually, a mild ale is an english beer with a low gravity, >relatively dark color, and good malt taste. So just tell your >buddies you were trying to make a mild ale... Not necessarily. At first milds meant an ale that was served as soon as fermentation was complete before an acetic or lactic sourness occured. At the start of this century it meant an ale that was less heavily hopped than a pale ale. TODAY, it usually is the lowest gravity beer that a brewery produces, but there are a few exceptions. You could still brew a higher gravity ale and call it a mild if you want, regardless what the AHA say :-) Who really cares, as long as we are having fun!

I am planning to brew an all grain stout and would like it to be similar to Guiness. I checked the recipes in the CM3 and found hardly two recipes using the same hops. There are 19 versions of Guinness brewed, just to make your job easier! However Foreign Extra Stout hops "...are a blend of several varieties, including Galena, Nugget and Target." p176, The Ale Trail, R.Protz, 1995, Eric Dobby Publishing I also read somewhere that Northdown was used a lot by Guinness Brewery, can't remember where though.

Date: Fri, 04 Dec 1998 07:19:03 GMT From: huskers at voyager.net (Jason Henning) Subject: pLambic hops, Heilemans, brewing again Hello- I've been in the process of brewing a plambic since Jim Liddel's BT articles. That's right, I'm aging hops. I left them in an open baggie, not a paper bag. Is my beer ruined? Anyway, I suggest that brewers date their aging hops. ("date their aging hops", I'm sure there a joke in there) - --- As a yute in dear ol' Nebraska, my Norwegian buddy used to steal his dad's beer. Svin only bought Heilemans. So we'd get 'full krausened' on Old Style (aka Dog Style). That was before Colorado Koolaid flowed in to the Cornhusker state. Those were the dazes. - --- I brewed my first batch of beer since moving to Detroit. I put it in my freezer (outside) with a heater (on a controller) thinking it would be cold enough to keep the temperature steady. Next morning, the temp was at 70. Then I checked an hour later and it was at 75. I grabbed my other controller and got the freezer back online. With the heater, the freezer, and a fan, that baby is in a narrow range of 65-68. I was unaware of just how much heat is generated by fermention. I wonder if I could heat my house if... - --- This batch was a no sparge batch. I was pretty disappointed with the whole process. I dropped from my usual 75% to 40%. I expected a drop in efficiency. I assumed it would be about 55% but 40% really hurt my feelings. 20 pounds of grain for less than 5 gallons of 1.056 beer. I also had some [no] sparge trouble. I got a lot of particles in the run off about half way through. I use a false bottom. I am at a loss to understand why I got particles after it had ran clear. Anyone else have problems like this. I doubt I'll do much no sparge brewing because of the sparging trouble and the dismal efficiency. At least for now. - --- No sparge is nice because you don't have to worry about heating sparge water. No need for a three tier stand, sparge tank, or a sparging manifold. Might be a good way to get started all grain brewing since it eliminates quite a bit of the hassles. Cheers, Jason Henning Big Red Alchemy and Brewing Clawson, Michigan Return to table of contents

This is to protect the *next* guy who works on your wiring - even though I'm sure you would remove all this non-standard wiring when you move. 2) If, Heaven Forbid, there were a fire in your home, and it was determined by the Fire Marshall to be an electrical fire, and the Fire Marshall found the non-standard wiring in your garage (and even if that wiring had *nothing* to do with the fire), your insurance company might use that as a pretext to void your homeowner's insurance, and pay you _nothing_.

I plan on doing 5 gallon batches. Hi, Ian. I have the 10-gal Gott and wouldn't trade it for the world. Actually, I have two of them. I use one with a Phil's Phalse Bottom and the other is my HLT (Hot Liquor Tank). Using a 10-gal Gott will allow you to do some higher-gravity beers (more grain). I don't know what a 5-gal Gott sells for but I think the additional cost for the 10-gal is very justified. It just gives you more options. I just went out to the Rubbermaid web site but couldn't find any info on the Gott. I submitted a question about them and would assume a response will follow. You might want to do the same thing. www.rubbermaid.com Hope this helps, Brad Plummer Georgetown, Texas ** Brewing, Shooting, Motorcycling. ** ** My wife thinks I have too many hobbies. ** ** Funny.

With this much air and storage at room temperature in order to carbonate, I get the feeling from this article that my beer is always oxidized by the time it's ready to drink! Andy, after reading the BT article by Fix, I came to similar conclusions. I believe he is assuming a counter-pressure bottle filler is being used. I do not use a counter-pressure filler either, and the most frequent comment I receive from judges at competitions is oxidation, no matter how close to competition time that I bottle. I must conclude from the article that unless I use a counter-pressure filler, my beer will always be oxidized within days after bottling. Comments from the collective?

I was kind of hoping someone would. Well, since you specifically asked, I do. Actually, it's a homemade version, but pretty close to the original. I've used it for several years (even before I converted to RIMS) with no problems. Never a stuck sparge, even with unmalted wheat. It seems to work fine in conjunction with the pump.

I was force-carbonating a 3-gallon corny keg last weekend for a party. You know the routine -- crank up the pressure and shake-shake-shake. During the project, I looked over at my 10-gallon corny keg and wondered if I could apply the same concepts to force-aerating wort. For example: Take my 8-gallon batch, decant it into the corny keg after the boil. Crank up the pressure using compressed air. Shake-shake-shake. Pump the beer into a fermenter. This will only work if you have a compressor and inline air filter (so you don't get compressor spooge in the beer). I really haven't had a problem with lag times or beer quality, but it's something I'm going to try. I'll keep the board posted...

We will be working for Abita, under their license. We are planning on a single test brew, and if things go well we may do it on a somewhat regular schedule.

Date: Fri, 4 Dec 1998 10:26:01 -0500 (EST) From: ALAN KEITH MEEKER <ameeker at welchlink.welch.jhu.edu> Subject: Headless Stout Question/Blow-Off?? Hi All. After seeing the lengthy rant by Scott Abene in the last HBD I can only hope I may squeeze this question in between all the flames that will probably ensue! Here's my question: Just made a simple all-grain stout. Base was 2-row with 1# roasted barley, 1# flaked barley and 1/2# cara-pils. Except for the roast, all were mashed together in a single 65degC step x 90 min. Yeast was 1084. OG was a bit low at about 1.034, FG was 1.005 which made me happy since I was going for a dry stout. The problem is that there is virtually NO HEAD to the final beer which surprised me greatly given the use of the # of flaked barley. I have always gotten good heading in the past whenever I've used flaked *wheat* but I thought one gets the same effect from flaked barley - is this not the case?? TO BLOW OR NOT TO BLOW - THAT IS THE QUESTION (No Monica jokes, please!) There's another factor here that I'd like to see some discussion on. I had filled my glass carboy fermentor quite full and pitched a LOT of yeast so I had LOTS of activity and therefore a fair amount of blow-off (used a blow-off tube) about 4-5 cups blow-off collected in total. Could this amount of blow-off have taken much of the head-forming/head-retaining compounds with it?? Through the reading I've done I believe the consensus is that the loss of the foaming blow-off material does not (significantly) reduce the head-forming ability of the final beer. This has always seemed counter-intuitive to me. Also I am wondering what is the general consensus on the use of blowing-off is. It seems that the reviews are mixed - some sources say it is *essential* in that it helps to remove fusel alcohols (though why these would prefferentially be collecting up near the top is a mystery to me) and insoluble hop resins in the krausen head which one wants to eliminate before they have a chance to drop back into the beer when the krausen falls. While it does seem that there are plenty of these sticky "resins" collecting up there it also seems to me that 1) they tend to stick to the top of the carboy and stay up there when the krausen falls and 2) that if they are insoluble to begin with it shouldn't matter if they fall back down as they will not go into solution (unless they do so slowly over time or as the % alcohol increases?). It also seems to me that if you are using a truly "top-cropping" ale yeast you'll be blowing off a fair amount of your active yeast which will be counter-productive. I have made beers where I had lots of blow-off and others where I've had none and haven't detected any major off-flavors or harshness that I could pin specifically on the beers that weren't blown off. So what's the collective wisdom (an oxymoron?) on this subject??

Date: Fri, 4 Dec 1998 10:46:39 -0500 From: "Penn, John" <John.Penn at jhuapl.edu> Subject: All Grain Ramblings, Duvel culture, Questions I always get a little chuckle out of those posts that say all grain only takes a few more hours (8?) why doesn't everyone make the switch. Well with two 3-4 yr old boys my brewing sessions usually start at 9PM and go for a couple of hours! Time? What's that? I've been interested in all grain but don't expect to have the time very often, mostly I'll stick to extract. I also try to brew two batches at once so that I limit my brewing to about once a month. Mill: Well I wanted to use my Gott cooler for a second time and my brand new Corona Mill. Thanks for the recent advice on adjusting Coronas, there are no instructions on adjusting the Mill. I tried the "tighten all the way then back off 1/2 - 1 turn." One turn seemed about right and then I tried maybe an 1/8 turn more backoff since I wasn't sure what the grains should look like. They looked more like Grits than the precrushed stuff I usually get from the homebrew store. No sparge problems though with the "grits". At any rate I crushed about 10# of grain (5# pale, 1.5# wheat, and 3.5# of 2 or 6-row). The grains were given to me by a friend who didn't have time to brew so I just made up my own recipe. I also added 1/2# of 90L German crystal malt to the kettle and used the hot sparge outflow to steep the crystal. Mash: My brewing consisted of about 20-30 minutes of crushing the malt the night before, getting up early to heat 3 gallons of water for mashing, and doing an ALL DAY MASH. My initial temp with about 3.1 gallons of water was about 165F and when I added the grains it seemed to drop to 150F which I think was probably just a low reading at the top of the Gott cooler, I was expecting a little warmer. Left it to mash all day and close to brewing time it was still 142F!!! Wow, that Gott works really well I was worried about it cooling off much more than that. Sparge: I cheat a little... Well, the wife was at a play so I boiled some water and did a sparge while the kids played a little and had some cookies ~7PM. That way when the kids were in bed and at my usual 9PM start I already had the sparge done. I'm still on the stove so I collected about 4 gallons of about 1.057-60 in a 5 gallon pot and another 1.5 gallon of about 1.020 in my 4 gallon pot for a second batch of extract based beer. I boiled the batch down from 4 gallons to about 3.5 gallons but then added water back to get about 4.5 gallons in the low 50s gravity. Boil/Yeast: The rest of the all grain batch went as usual and by 11PM I was done with both the extract batch and the all grain batch and cleanup. I used the Duvel starter that I tried a month ago, starting with the 11 oz bottle, stepped up to 1/2 gallon, then poured off a quart and added another 1/2 gallon of fresh wort. Both batches started the next morning using the Duvel starter but they are going relatively slowly, maybe 1 bubble per 5 secs instead of 1 bubble/sec. I thought maybe the yeast thought 68F was too cool since my usual ale yeasts are much faster. I looked at Rajotte's Belgian book again last night on yeasts and he mentioned that secondary yeasts added at bottling time tend to be slow starters. Maybe I've got just the bottling yeast in my Duvel. Anyone know for sure about this yeast? I guess for now it seems to be fermenting even if it seems slow so I'll just give it a few weeks before bottling. I still don't have a good bulkhead connection to my Gott cooler, just a small hose jammed into a cutoff water spigot and a clamp to control flow. I need to work on improving that. I spent some time at the hardware store but couldn't find a good system. My rectangle of copper tubing seems to work well with no sparge problems even though I thought my holes were too big. Any help here on bulkhead fixtures? Thanks for all the wonderful inputs on the HBD and especially Karl and Pat for keeping the HBD going. As for me, I thank Charlie Papazian for his book that got me started. Though I think Al K's Homebrewing I book is much better and more thorough for those looking for a good starting book.

I'm replying to this and ccing the HBD because I thought it was of general interest and Hugh agreed. Indeed the positive controls showed no growth and even now they show no growth even upon retesting. Does this mean the media won't support growth? Highly unlikely since these same bottles of media were used to test mammalian cell culture media and the positive controls grew microorganisms. In this case we cough directly into the growth media. But you'd be surprised at the incidence of positive tests due to operator (i.e. grad student) error even when working in a class 2/Type A laminar flow hood. > > wouldn't it make more sense to store the tubes for 2-4 days > (weeks?) prior to inoculating the culture media? That way > the relative ability of the storage media to support growth > could be better evaluated. Maybe. First off the reason for this testing was to evaluate whether my pompous statement about buffer promoting growth better than water was true in the specific use of storing yeast. If microorganisms end up in the water or buffer and then they are transferred to the YM and MRS (both very rich growth media) then they should reproduce. We should not have to wait. But as a follow up I still had all the tubes when you sent me this e-mail. So I retested all the samples I had. It's been something like 10 days and again none of the samples or controls are showing any growth. >I'd think 2 hours is too short > to get much growth. Also, since the yeast would be stored > in the media for months, there'd be plenty of opportunity > for tiny amounts of bacteria to grow, esp. if phosphate > is a nutrient or growth enhancer. But it does not matter. If bacteria fell into the water or buffer, they would in theory not die in the two hour time frame. So then when a sample is put into rich growth media the microorganisms should thrive. And again further testing failed to show positive growth. > > Also - wouldn't it make more sense to use viable bacterial > cultures for the positive controls? inoculate w/ aceto > or lacto bacteria (or even the dreaded pediococcus ;-). No. Again the reason for doing this test was to test, in general, how well thsi technique works and is it subject to contamination. Let's look at this in a real world situation. I choose the 12 X 75 mm tubes because they represent a tube size that would likely be used by those storing yeast in water or buffer. And I then left them out for two hours to represent a worse case scenario. Typically if one were storing yeast in water the tube would only be open for a matter of seconds. I'll point out though that this testing was done in a lab. But it is a far from clean lab, we do cell culture, but we also do various chromatography work, animal studies, molecular biology stuff, and I have my running stuff hanging in here also. I also placed the tubes in areas under ventilation vents. So I wanted this to be a test that some what represented a real world situation, not some ideal that 99% of you will never achieve. Now this is a single study, done in one place. I have not a study with tubes that contain yeast and are then checked for contamination. This requires adding various combinations of antibiotics and antifungals to test all the permutations. I'll get right on it. :-) But I think in general (no this isn't a PhD defense meeting so I'll go out on a limb and make a few leaps of faith) that this shows that neither water nor buffer are very good growth media alone. And that one can safely do a certain amount of culture work with out risk of cross contamination provided one is careful and uses good techniques. Yes I've been doing this stuff for years. I think it shows that water or buffer stored offer reasonable alternatives to petri dishes or slants for the average person. 500 grams of USP grade pottasium phosphate monobasic can be had for ~$30. This is enough to make alot of 2% solution. I have often wondered why some enterprising induhvidual does not distribute yeast cultures in water or buffer. A homebrew shop could have 100 tubes in a very small space. If one used polypropylene tubes of 1.5 ml capacity this would work well. All the brewer would have to do is invert the tube a few time to suspend the yeast, wipe of the tube with 70% isopropyl and pour the contents into 100 ml of wort. And then step up again. One could even make kits that include the tube of yeast and a 50 ml tube of sterile media. In theory one could have 10 strains of yeast on hand in a very small box. And there would be less waste since the storage time for these would in theory be longer than that for things like wyeast or white labs since people would know stepping up would be required. WRT to water vs buffer experiments still need to be done to look a the kinetics of the loss of viability using tissue culture/endotoxin free water and tissue culture grade buffers. > From: "RANDY ERICKSON" <RANDYE at mid.org> > Subject: RIMS Questions --- summary > > A while back I asked for advice on RIMS false bottom designs, > with particular emphasis on those suitable for a GOTT that do not > require a lot of different parts. I am using a phils phalsebottom in my RIMS unit. I am using a stainless steel pot not a gott. I took a silicone stopper and plug the hole in the center and just use the thing as a true false bottom with a drain underneath. I also put a piece of tubing around the edge to act as a gasket to make sure it stays in place. and I put some stainless bolts into it near the center to keep it from collapsing so much. It works OK, but I am looking at getting some a piece of perf steel from Small Parts that has more open area, even though I have not had any problems so far. I've only used my RIMS 4 times. > Beer is our obsession and we're late for therapy! >From the hbd header. Now let's examine this statement. If one has an obsession then this is indicative of Obsessive-compulsive disorder (OCD). One can then live with it or go to therapy and there are also various medication available to treat this (Selective Serotonin Reuptake Inhibitors for example, Prozac, Paxil). So If one has an obsession and is "late for therapy" then this indicates to me that one is trying to deal with their obsession and overcome it.

Date: Fri, 4 Dec 1998 11:23:52 -0500 From: "Houseman, David L" <David.Houseman at unisys.com> Subject: Lag times John Varaday's data about the use of Air, O2, Shaking and Spray methods of getting O2 into solution is interesting. But I don't know if one can draw a conclusion about whether the longer/shorter lag times are beneficial or not from this. The point is to get yeast growth and activity as quickly as possible to beat the other beasties to the goodies. Yeast growth and reproduction is greatest in the presence of O2 and other required nutrients. Should yeast be placed into a wort medium that was not conducive to growth but rather more quickly to fermentation, it would seem that you might recognize the evidence of feremenation (bubbles out the air lock) sooner with less OK than with a much higher concentration of O2. But because of the smaller volume of yeast be in worse shape in terms of being in competition with other yeasts and bacteria than the samples with the higher O2, rapidly growing brewers yeast colony and less resulting CO2 early. I'm sure that the biochemists on-line can provide more detail but the logic seems to be in favor of greater yeast growth, not necessarily which start producing CO2 the soonest.

(plus why would you lager an ale, excluding the german styles?) i think also you have to make sure to start ramping the temperature down while there is still some fermentable extract in the beer. how you determine that is... well, it's up to you. brew hard, mark bayer (great mills, md) Return to table of contents

One person mentioned that this malt tends to clump during mashin, and great diligence is needed to get it mixed thoroughly. This problem sounds like what people have said about Crisp Maris Otter malts, so perhaps Beeston uses Maris Otter as well. Someone else mentioned that his Beeston ales tended to be more cloudy than his Briess ales. I'll look for this, but I don't care that much.

Adding pumpkin juice to your boil will possibly add some pumpkin flavor and some unfermentable starch. See how it comes out, but next year, add the juice (or the pumpkin mush) to the mash. Good luck.
