---------------------------------------------------------------------- Date-Warning: Date header was inserted by grove.iup.edu From: jmglenn at grove.iup.edu (James M. Glenn) Subject: Advice on thick & maybe stuck darkie? On a modified Porter recipe I got from who knows where, the fermentation activity quit after about a day and a half. My OG was around 1.072. I pulled a sample to see what might be going on - SG of 1.032, and a taste reminiscent of molasses. The recipe I used called for 2 lbs Crystal, 1/2 lb of both chocolate and black patent, plus 1 lb dry light extract and 6.6 lbs liquid light. The only thing I did different this time was I rinsed (150 deg) and squeeeeeeezed (again and again) the 6 boilbags of grains until they were absolutely clear. Thinking maybe the wort hadn't gotten enough oxygen, I pulled another sample and boiled it, added cold and vigorously aerated it, and added yeast in a 2-qt jar with lid and airlock to get myself a yeast culture that could get it going again. The yeast sank to the bottom of the jar and went right to sleep, nary a bubble. Now I'm thinking that maybe it really IS all done, and the high SG is due not to stuck fermentation but to a high percentage of unfermentables due to all my squeezins. Any suggestions? And would you think it's worth bottling/conditioning if my latest assumptions are likely? James Glenn jmglenn at grove.iup.edu Return to table of contents

Date: Sat, 2 Mar 1996 23:17:05 -0500 (EST) From: Carl Howes <carlndeb at mv.mv.com> Subject: chili, copyright In #1972 Scott Rudolph asked about microwaving chili peppers (I'm not reproducing the post here because I find that seriously annoying). My experience with spicy foods is that microwave heating intensifies the spiciness, sometimes a LOT. Not necessarily a bad thing, but definitely one to be aware of. I'll let a biochemist take a shot at why this happens. After almost two years away, I've noticed a couple of seemingly derisive references to copyright. I also recall a fleeting reference to this issue a few Brewing Techniques back. Could someone supply references to when this was a thread? Carl carlndeb at mv.mv.com Return to table of contents
Date: Sat, 2 Mar 1996 23:26:39 -0500 From: GSHUTELOCK at aol.com Subject: Boston Beer Bottles I know were not supposed to use "non-returnable" bottles for our homebrews but I have a question about reusing Boston Beer/Sam Adams bottles. I used to buy my 12 oz bottles from my local brew store (about $ 9.95 and tax for a case of new empties). Then I discovered Yuengling Porter in returnables at my local beer distributer (about $ 16.50 a case filled with a wonderful commercial brew) so I'd drink the porter and keep the bottles for my homebrew. Well, the other day I purchased a couple six packs of "Sam Adams" Scotch Ale and Double Bock beer. I was looking at the empty bottle and didn't find the usual "NO RETURN/REFILL" statement. Also the bottles looked suspiciously like my new 12 oz bottles. I weighed the brand new bottles (about 8 oz of glass) and then my Yuengling porter empties (about 10 oz of glass), and finally the "Sam Adams" bottles - 8 oz of glass! My question is does anyone know any reason I couldn't or shouldn't reuse these "Sam Adams" bottles. Granted they are not the extra tough reusable bottles the commercial breweries use, but they've got as much glass (and I figure strength) as the empty bottles I'd been paying good money for. Stacked up with the new bottles I can't even tell the two apart (shape or weight). By the way, good old inexpensive "Arm & Hammer" washing soda (aka extremely overpriced "B-Brite") even soaked off the resistent "Sam Adams" foil labels in under 30 minutes.

Date: Sun, 3 Mar 1996 02:06:50 -0500 From: TAyres at aol.com Subject: I'm Back in the E-Mail Loop -- and SUDS for Mac Redux! Hello, All! The bad news is that anyone who has tried to reach me by E-Mail since February 24 has gotten mail kicked back to them because of, shall we say, a "dispute" over billing with America On Line. The good news is that I'm now back "in the loop" at TAyres at aol.com. So fear not, you have not lost contact with me!!! I'm now back on line. Please resend anything you may have tried to send me since 2/24. The second bad news is that this loss of AOL for more than a week posed a particular problem with regard to two questions I had raised on homebrew group mail and newsgroup lists such as WortNet, Homebrew Digest, and Lambic Digest. Pardon my resubmitting these queries, but I never got answers the first time because of the AOL snafu, so I'd like to try again. Here are the two queries, one to all parties with knowledge and the second to "lambic geeks" like me: 1) Does anyone know of any SUDS 4.0-like shareware for the MAC platform? If so, what is it like and where can I find it. I'm very intrigued by SUDS, which I can use on a 486 at work, but I run MAC most of the time at the homebrew shop I coown and at home -- would love to find something as good as SUDS for Mac. Suggestions? And where do I find it? 2) Second questions is regarding my a framboise lambic I currently have in production. Sour-mashed, pitched Wyeast (pseudo) Brett and Boon/Cantillon slurries, plus Wyeast 1056. Lacks pedio character. What is the feasibility of pitching pedio at BOTTLING time. I'm considering doing this with pedio from GW Kent. Any thought, lambic freaks? Please post to Lambic Digest or respond via private E-Mail -- now working again!!! -- at TAyres at aol.com Sorry for all the waste bandwith repeating this silliness -- AOL f**cked me over, what can I say?

Date: Sun, 3 Mar 96 00:28 PST From: robtrish at mindlink.bc.ca (Rob Lauriston) Subject: changing channelling Al K. quotes me on stirring the grain bed during lautering, "The stirring also counter-acts channelling." He writes, >I contend that stirring the grain bed increases channelling. >This is how I justify this. Consider water running slowly through the >grain bed. Now here comes this rake or spoon that cuts a gorge into >the grain bed. The gorge disappears as quickly as it appeared because >there is a layer of water on top of the grain bed. What flowed into >the gorge? Grain? Water? I think that you could either increase or decrease channelling according to exactly what you did. When I've been impatient with gummy slow wheat lauters, I've cut the bed with a knife praying that more liquid would go through, *any* liquid --- extract, schmextract. OTOH, with a 6 to 8 inch grain bed, I often stir up the top couple of inches of grain when there's only about a half inch of water on top. I stir the *complete* area of the top of the mash with the result is that the top looks like a rather thick porridge, like the original mash. Besides eliminating channels, the point of doing this was to mix the pasty teig in with other mash particles. This is quite different from my knife cutting or the cutting that the rakes of a commercial tun would do. There is no gorge into which the stirred part flows, I don't think. If there are any channels remaining, BOTH water and grain flow in. Hopefully the water keeps going through the surrounding bed like a normal sparge, the grain is left behind and voila, the channel is filled in. >I theorize that cutting through >the grain bed actually creates a "path of least resistance" which subsequent >sparge water runs through. Anybody willing to agree with me on this? I agree with this. I tread with trepidation into the touchy territory of terminology, but do we want to distinguish 'stirring' from 'cutting'? - -- Rob Return to table of contents

Date: Sun, 3 Mar 1996 11:41:42 -0600 From: Tamth at mail.utexas.edu (Tam Thompson) Subject: Yes, you can re-use primary trub In response to Darcy Munger's inquiry on 3/2/96: Yes, you can re-use that primary trub. I used to do it all the time. You can usually re-use that slurry about three times before it starts to mutate too far into the unusable range. This will save you much money on Wyeast. The caveats: as Darcy mentioned, of course you must put it in a sterilized bottle (be sure to do this using a sterilized funnel or hose) with an airlock on it, and store it in the fridge. I like to use Duvel ale 12-oz bottles, since they are very short and squatty. I can put a stopper and airlock on top of them and they still aren't very tall. Also, be sure to label them with the date, the batch they came from, what Wyeast it originally was, and how many times you've used it before. When I do weirdo brews, like organic ginger-pepper honey lager, I don't save the slurry, since it's been flavored. I save it only from generic-type brews, like porter and Vienna lager. I have question, as well: I have always saved this slurry out of the primary. On my recent porter and Belgian white (two separate ales), I didn't remember to save any until bottling. You CAN do this with the slurry from the secondary, can't you (assuming that you haven't waited eons to bottle, or frozen your yeast, or anything)? Hope this helps, and thanks in advance for answers, Tam Thompson Tamth at mail.utexas.edu Return to table of contents
Date: Sun, 3 Mar 1996 13:53:38 -0500 From: CASteveB at aol.com Subject: It's Alive (Goofy Gravities Cont.) On 2/29 I wrote about my fermentation slowing way down with the SG at 1.060. I took the measurements while racking to the secondary. Now, 3 days later, the beer is *alive* again! There is a nice 1 to 1-1/2 in layer of kraeusen and it is bubbling away. (a bubble every 2 sec.) I was careful not to areate the beer while racking, so I don't think a great increase in available O2 is the cause. Could it be a little disturbing of the trub and redistribution of the yeast that would revive them? just a shot in the dark on my "Great Adventure in Beerland!"

Date: Sun, 3 Mar 1996 15:01:11 -0500 (EST) From: "Kieran O'Connor" <koconnor at syr.edu> Subject: Mac Programs Part II Here's another Mac program available from Info-Mac, the Mac shareware archive: The Info-Mac Archive is available at 50 public and private sites around the world. For the site list, request it by mail (address below), or try: <ftp://mirrors.aol.com/pub/info-mac/help/mirror-list.txt> Also accessible by ftp. Help files and indexes are also in info-mac/help/. Attached please find the FREEWARE BrewMeister v1.0 by Frank and Becky Grimaldi. There is a serious lack of shareware/freeware homebrew software for the Macintosh. This software is a beer "recipe database and recipe analysis tool" according to the readme. I just got this from a friend who got it on Compuserve. (Thanks, Lance!) I've scanned it with Disinfectant 3.5, but haven't used it yet. It is geared more to the "all-grain" (scratch if you will) homebrewer, rather than the extract brewer. Calculates original and final gravities, potential alchohol, IBUs, and Color. Looks pretty decent if you are into homebrew and use a Mac, especially since there isn't much other shareware available.

Date: Sun, 3 Mar 1996 16:01:22 -0800 (PST) From: Jim Cave <CAVE at PSC.ORG> Subject: Channelling. No. Im not a hydrological engineer, just a stream biologist. Obviously, erosion develops with water velocity and with time--streams widen with time because of erosion. The stream analogy with a grain-bed would indicate that channelling would also develop with time. Anything that forces the process to start over again (e.g. stirring) would minimize the development of channels. Mind you, recirculation may be necessary to reset the grain bed and minimize rubidity of the wort. Raking the grain-bed results in reducing the compaction of the bed and (according to Richman and Warner) is used in lautering of decoction mashes. I've been told by a commercial brew that rather than suffer through a stuck mash (which often results in channeling--least flow of resistance and all that) complete stiring and reseting of the grainbed is preferable. If the mash has shown signs of sticking, it is best to do this right away than deal with the concrete afterwards. I've seen signs of channelling in the two times I've had a stuck mash. There was a mottling of the grainbed and parts were sweet and others were not. I suspect that I made the usual mistakes--recirculated too quickly, and too much; too fine a grind; too much grain. Stirring at least lets one give it another go and slow down the speed of recirculation. It seems that a speed that you can get away with using 24 lbs of malt is higher than with 35 pounds.

California is pleased to announce the results of our third annual competition. We would like to thank all brewers, judges, and stewards who participated and helped to make this a successful event. Once again, the proportion of excellent beers we received was very high. Individual score sheets and ribbons will be mailed out to the brewers within a week. The trophy for Best of Show, an engraved beer glass with the QUAFF logo, the competition information, the brewer's name and beer will take a while longer since it is being custom made. Due to some categories having insufficient entries, those categories were combined with other categories for purposes of scoring. Ribbons were awarded for the combined categories together. To prevent beers which are not "Ribbon Quality" from placing for an award solely because they happened to be the only beer entered in a category, minimum scoring requirements were placed. To be awarded a First Place Ribbon, a minimum of 35 points must be scored, for Second Place, 30 points, and for Third Place, 25 points.

Is it worth doing? I used to follow that same process, based on Dave Miller's book. I stopped doing it when I gave some thought to the contents of the "trub" I was leaving behind in the settling tank. One of the big components is yeast! I spend days building a decent size starter to pitch into my beer, then rack the just-beginning-to-ferment wort off the top of it a few hours later. Sure, there's lots of yeast in suspension, but not as much as I'd like to have. One of the results of the process back then was that my beers were much more prone to diacetyl (the noun that means the same as 2,3-butanedione ;-). Large quantities of yeast lead to more rapid fermentations and are necessary for reducing diacetyl at the end of primary fermentation. Eric in Newport, RI Return to table of contents

It's not "diacetyl followed by what?", but very simply "acetyl acetyl"! Hence colloquially "diacetyl" although it is strictly speaking wrong: it should be (and is) "biacetyl". In such a context, "di" means "two of A attached to the same B", while "bi" means "two A attached to each other". Others of the same type: biphenyl, bibenzyl, and bivinyl. ------ And now for something completely different, KennyEddy at aol.com asks: > Anybody know much about Clorox's "new and improved" biodegradable bleach? > It's supposedly a "blend" of sodium hypochlorite AND sodium hydroxide; That's what the "old" bleach always was. > supposedly it turns to saltwater (NaCL I presume) after a while.

Thanks for I would recommend entering it as a specialty beer, giving it a title that implies that you're trying to brew a historic porter, from back in the days when porters tasted a bit smokey. A porter judge would notice the smokey/phenolic character in sharp contrast with the other un-peated porters in the flight. Would tell you to lose the smoked grains or enter the beer as a smoked beer if they knew it was from smoked grain, or would tell you that your beer is probably infected if they picked up just the phenolic character of the smoke. The smoked beer judge would say that your *lightly* smoked beer doesn't have nearly enough smoke in it. It won't stand up well after a few great big smokey Rauchbiers.

I suppose if you only drew a rake through the mash once, that you would simply create a new channel, but in a proper system, the rakes move slowly through the grain bed -- and usually deepen over the course of the mash/ lauter/ process. This makes is impossible for the water to find fractures in the bed and form channels, as the fractures are continually broken up. >Channelling, for those who don't know, but still haven't paged down, >is sort of like a 3-dimensional river that runs through something (soil, >a gravel filter, a grain bed, whatever).

I have had excellent results with one step infusion mashes. I get about 82% extraction and beautifully clear runoff. However, each time I've tried a multiple step infusion mash (with a protein rest, conversion, and mash-out) I end up with a stuck sparge. <snip> - ----------------- I have experienced this doing step mashes in my Gott too. It took a couple of batches, but I finally realized what was causing it. The thin final mash allows finer particles to form a thick teig (as recently discussed in HBD). I don't think it has anything to do with the "weight of the water" on top of the grain, but rather it is the way the grain bed forms in such a dilute mash: heavy particles at bottom, teig-forming "grain dust" settling last on the top. Kind of like river sediment where the big rocks settle first, and so forth, until the only thing still suspended in the water is the silt particulate, which settles last. If you use adjuncts such as corn or oats, the teig is very pronounced and you get either channeling down the sides of the cooler, or a stuck runoff, both not a good situation. My ways around this, as you appear to have already discovered, are to scratch the surface of the grain bed often during the sparge (or even skim off some of the teig as it forms), or open the runoff flow rapidly at first to set the grain bed before it has time to do the gradient settling (or both). The problem with an intial wide-open lauter spigot is you get a LOT of cloudy liquid you need to recirculate, but you have to recirculate it slowly, and only after the grain bed has formed a fairly firm consistency. It feels like a bucket brigade! It's enough to drive you to build a RIMS setup! But seriously, what I now do is dough-in thick at .5 qt per pound for the protein rest, add boiling water to bring to conversion temp, and skip the mash-out and use hotter (175F-ish) sparge water. The grain bed temp stays under 170F because the temp differential of the 175-180F sparge water and the 152F mash is small. I am not trying to re-hash the discussion about whether mash-out is required or not. I'm just saying that's what _I_ do to keep the mash in my Gott from getting too thin to point it becomes a PITA to sparge. You could, of course, use decoction or steam injection to raise mash- step temps, but that's a whole different story. Or, just do single-step infusion ;-). Please, any brewing science students, feel free to enlighten us on the dynamics of mash consistency and lautering. Or why the protein rest actually works better in a thick mash, while conversion works better in a thin mash (which is a good thing for us Gott mashers!).

He suggested instead using liquid nitrogen, which he has ready access to through work. Off hand I can't think of a reason why (with appropriate safety precautions) this wouldn't work. As has been discussed here, wrt carbonation, N2 doesn't react with beer. I can't imagine that there is an infection risk from it since it is pretty cold (~77 K). And the cold break would probably be awesome with cooling occuring in a very few minutes (< 1?). Can anyone think of any problems beyond the safety issues (i.e. the N2 flashing into gas and throwing hot wort all over the kitchen)?

I never stir my mash, but sometimes I have to increase my sparge water flow rate, mid-sparge. Once or twice, I've fumbled on this operation and have subsequently disturbed the grain bed a little (8" grain beds or so). A quick look at my runnings showed that they had gotten a little cloudy suddenly, but then cleared back up quickly. I think that if you were to: 1. stop taking runnings, 2. stir the grain bed, 3. restart taking runnings into another vessel, 4. recirculate till the runnings are back to "pretty clear," 5. restart putting the runnings into the kettle, you may be getting a *little* more extract than if you just let the thing run without disturbing it. Remember that 3-hour lauter that I mentioned in passing? During it, I was very tempted to stir the grain bed (who wouldn't?), but I knew the problem was due to the 43% rye malt and my botched beta-glucan rest (overshot!) and not because I had a defective grain bed. In the end I got 32 points/pound/gallon and my final runnings were (after temperature adjustment) 1.013!!! I could have gotten 34 points/pound/gallon if I had the patience to wait another hour. In three hours I got only 6 USgallons of runnings in stead of my usual 7.5 or 8. >>I theorize that cutting through >>the grain bed actually creates a "path of least resistance" which subsequent >>sparge water runs through.
