---------------------------------------------------------------------- Date: Sat, 14 Oct 1995 10:23:21 -0500 From: gscott at io.org (Geoff Scott) Subject: Beta-amylase at 140F (60C) Steve is looking for a discussion of lower temperature saccharification rests. It seems clear to me that although slow at 60 degrees, saccharification is going on. As Steve points out, maximum fermentability is achieved somewhere around 60. But that's as far as we agree. Steve: >I'm not overly enamoured of the higher amylase activity at 65C as a >homebrewer. A-B may be in a hurry when they brew; I can afford the >extra 30 minutes. A homebrewer's greater difficulty is in controlling >the process. I suspect that by timing a primarily beta-amylase rest >and a primarily alpha-amylase rest that I can achieve tighter control >and greater reproducability of recipes. The alternative is to choose an >intermediate temperature which results in the correct balance of alpha >& beta amylase activities (like your 65C). Controlling mash results by >this fine temperature control is relatively difficult. It's interesting to note that although a mash at 60 gives max fermentability, a mash at 65 gives max extraction. I know, craft brewers are not mainly concerned with extraction but it illustrates that beta and alpha amylases do not work in isolation. For this reason I don't think it can be as neat as separate rests for beta and alpha at their respective optimum temperatures. In a mash around 65 where both are active, I can think of two ways alpha helps beta do its job. Alpha amylase is the more important liquefaction enzyme, it facilitates water uptake in the starch granules so that beta can get to work. Secondly, alpha can break 1-6 links connecting the side chains of starch to make more ends available to beta. So Steve, I'm afraid you'll have to stop mashing so low and come up to around 65 like some of the rest of us. (Just kidding) To be honest, my main objection to low saccharification rests is the resulting beer - too dry for my tastes. regards, Geoff Scott gscott at io.org Brewing page http://www.io.org/~gscott Return to table of contents
Date: Sat, 14 Oct 1995 11:59:48 -0400 From: WALZENBREW at aol.com Subject: Aluminum Pots In HBD #1854 Randy Barnes, San Diego, writes: >In the latest Zymurgy special issue the author of one of the > articles commented that there was still some debate in homebrewing >circles over whether aluminum pots were acceptable for use in brewing. >My understanding was that the aluminum would undesirable affect the >beer. Anyone out there using aluminum? It's sure cheaper than >stainless. I used a 15 gallon aluminum lobster pot that I bought for $25 at a closeout store for about four years. I had no trouble with it and made excellent beer. Only problem with it was that it was impossible to find anyone willing or able to weld a drain pipe and valve on it, which is why I sold it and bought a Vollrath stainless 15 gallon pot. I wanted the convenience of no more damned hot wort siphons, and the advantage of a false bottom for sparging all-grain batches and separating leaf hops (and hot break) from the boiling wort at boil's end. The only difference I noted was in the fermentation. Certain ale yeasts took 50% to 100% longer to ferment out completely when the wort was boiled in aluminum. In other words, instead of a 7-10 day primary ferment, it always took about 2 1/2-3 weeks. Of course, the beer tasted excellent, so I never felt this to be a problem. And re-pitches of the yeast remained viable and continued to make good beer. I won about eight ribbons at various competitions with the beer brewed in this pot. Alzheimers from aluminum pots? Paranoid bullshit. Autopsies performed on Alzheimer's patients show elevated levels of aluminum, granted, but nobody's been able to prove that aluminum is the cause rather than a symptom. Probably because aluminum is so common in so much of the food we eat - it's almost impossible to keep from ingesting _some_ aluminum in your diet. An article in the New York Times cooking section a few years ago demonstrated that even with low-pH foods (like beer wort) the increase in ingested aluminum from aluminum cooking pots is negligible. So if you have an aluminum pot, and don't mind not having a drain valve and spigot, don't be afraid to use it. You'll make great beer with it. Prosit!

Date: Sat, 14 Oct 1995 12:53:25 -0400 From: IHomeBrew at aol.com Subject: Brewing Software Charlie, I too, don't really like the brewing software that I've come across so far. Currently, I use a hodgepodge of Excel spreadsheets that are getting my by until I can take the time to sit down and write my own program (I am a senior CS major at The University of Puget Sound, Tacoma, WA). Right now, I am tossing around the far fetched idea of proposing to write a homebrew recipe formulator next semester for my independent study class (I think I can pull the wool over their eyes by proposing it as a software engineering project -- boy I hope none of my profs are reading this! :-{ ). Will make sure I post the BB location of it if and when I ever get around to coding the application. Prost!

Date: Sat, 14 Oct 1995 12:13:31 -0600 From: John Adams <j_adams at hpfcjca.sde.hp.com> Subject: Road Dog Ale / Broadway Brewing For those of your you have not seen Broadway Brewing's Road Dog Ale I have faithfully transcribed both the front and back labels and the very rare flyer that hangs around the neck. John Adams (from the label on the front) Road Dog Ale Scottish Ale <illustration by Ralph Steadman> Good beer No Shit "Good People drink good beer." Brewed and bottled by Broadway Brewing LLC, Denver, Colorado exclusively for Flying Dog Brew Pub, Aspen, Colorado (from the back label) This label represents one of many (some unmentionable) collaborations between infamous road dogs Ralph Steadman and Hunter S. Thompson, and to our knowledge, it is the first label to grace a bottle of ale that was created by renowned international artist and gonzo a journalist (who by the way net in their youth at a racetrack). Although this art will only last through the months of Fall, look for the new year to bring yet another outrageous effort. "There is an ancient Celtic axiom that says 'Good people drink good beer.' Which is true, then as now. Just look around you in any public barroom and you will quickly see: Bad people drink bad beer. Think about it." -- Hunter S. Thompson (from attached flyer) Ale According to Hunter Ale has long been the drink of thugs, convicts, rowdies, rakes and other depraved outlaws who thrive on the quick bursts of night energy that ale brings. In the 17th century England gangs of ale-crazed fops would often fight to the death in all-night brawls on public greenswards, which terrified the citizenry and left many of the infamous "youngblood horsemen" chopped up with grievous sword and dagger wounds... These were the Wild Boys of Olde English story and song, rich sots on horseback who amused themselves in London by riding out at night, ripped to the tits on strong ale, and "pooped old ladies into empty booze-barrels and rolled them down steep, cobblestone hills with crazy screams and shouts"* "If you must roll ladies down hills and you don't want to pay the bills Try to be, and clean off their lice with powerful Road Dog Ale." -- Hunter J.

Date: Sat, 14 Oct 95 14:18:07 -0400 From: Jeff Renner <nerenner at umich.edu> Subject: Re: Australian yeast In HBD 1857, Bryan (bgros at mindseye.berkeley.edu) comments on the difficulty of deciding which part of his mash he should take the temperature of, and then says: > My second question is whether anyone has experience with > the Austrailian ale yeast from Yeast labs (I think). > Some members of my club professed great results with > this yeast, and remarked that it seemed to ferment out > in three days.

I notice now > that most of my bottles are overcarbonated. Seems like > this yeast keeps going slowly for quite a while. I'm > going back to Wyeast. Any comments? First of all, let me offer this disclaimer, which other HBDers have heard before: Dan McConnell, PhD, owner of YeastLab, is a good friend of mine, and gives me starters as part of his Quality Assurance program. So I never buy yeast. However, as I have stated before, and as Dave ("I'm not from here, I just live here") Draper gleefully quoted me, I can't be bought for a mere $3.50. Furthermore, I have a bit of a paternal feeling for this particular yeast (A01), since Dan cultured it up (before he started YeastLab) from a bottle of Cooper's Sparkling Ale hand carried from Oz by Aussie friends of mine, back before it was available here. At the time, we didn't know anything about the yeast, but I was intrigued by the ale by Jackson's description of it and the brewery (the brewery that time forgot, so to speak) in his original World Guide to Beer. It became and remains a favorite yeast of mine and of others in the Ann Arbor Brewers Guild. It is a good, general purpose ale yeast that delivers a nice, complex fruitiness, especially when fermented in the upper 60s to low 70s. It also seems to me to emphasize the hops, as opposed to other yeasts which seem to emphasize the malt (which I also like in some styles). Right now, I have on tap two ales fermented with this yeast: a best bitter (a bit darkish with dark medium crystal and some special B; and a nice "cascadey" American pale ale (I called it Sierra Foothills - at OG 1.040, it doesn't quite reach the summit of Sierra Nevada). The yeast makes a nice contribution to each of these somewhat different ales. Interestingly, the bitter, which was pitched from a culture, keeps on ticking over, providing a continual source of keg pressure. The American Ale, which was repitched from the bitter, fermented out and quit. I kegged it, and a week later tapped it and was surprised to find it had virtually no pressure. Actually, this is a bit of a bother, since I like to have the continual evolution of just enough CO2 to keep the beer conditioned without a CO2 tank. So, with all of that said, let me suggest that the source of your and my continuing fermentation (more bothersome for you, since you have bottled), is variation in the grain bill and mash schedule. As you have pointed out, different parts of the mash are likely to be different temperatures, making it hard to say just what the oeprative temperature actually is. Dave Line recommends a higher mash temp for "ales from the wood," so that the wort will have more dextrins, which provide that very slow fermention that continually provides conditioning. (Dextrins are nominally unfermentable, but it seems to me that some of them, perhaps the shortest, do so very slowly, ultimately producing a thinner, drier, more carbonated beer over time). I think that crystal malts may provide some of this as well. Perhaps a slightly lower mash temperature would produce a better fermenting out wort. The other possible explanation of continuing fermentations is underpitching and/or under aeration. I assume that since you repitched, this is not your problem. Anyhow, I don't think this is due to the yeast strain. I've used it dozens of times and have not seen it any more or less than with any other yeast.

Sassafras contains safrole, which is a carcinogen, hence the ban. Nutmeg is a hallucinogen which will trash your liver, but it's legal, because nobody uses those amounts (unless they're in prison.)

If it's proven to cause cancer in lab rats, they have to ban it. >I for one would be REAL curious to know the level of danger present Probably not much, unless you're exposed to lots of other carcinogens/mutagens at work.

Date: Sun, 15 Oct 95 08:27 EDT From: cdp at chattanooga.net (C.D. Pritchard) Subject: Homemade Malt Mill I've just completed a single roller malt mill. It crushes the malt against an adjustable tangential steel plate. I puzzled for a long time over what to use for the roller since I wanted to avoid spending alot of $$$ at a machine shop on a metal one. I decided to use concrete. Got a 4" diameter PVC pipe cap, drilled a 5/8" hole in it's center, inserted a 5/8" steel rod which had a 5/16" rod inserted into a hole (serves as torque reinforcement and enhances the bond of the concrete to the shaft). The thing looks like this: +========= <----------4" pipe cap form | ++ | ||<---------------5/16" rod | || +-------||-----------+<---5/8" rod shaft +-------||-----------+ | || | || | ++ +========= I used fast setting "quickcrete" to fill the pipe cap. It's available in 10 pound yellow plastic buckets and has no gravel in it. After the concrete set (24 hours), I removed the pipe cap by cutting slots along it's periphery with a table saw and then pried off the plastic in chunks. The roller was then mounted into a wood frame with ball bearings. It was a tad out of round and had a slight taper along it's axis so I used a right angle grinder with a masonary disk to true it up. Did it by rotating the roller while applying the grinder. The mill works great and cost less than $20. I'd worried it might produce too much flour, however, in a pound of grain, there's only about a tablespoon or so of flour. I'm doing my first partial mash today.

Date: Tue, 3 Oct 1995 09:39:50 -0400 From: PatrickM50 at aol.com Subject: Copper pipe epoxy Tim Laatsch asked about using epoxy for his copper pipe assembly instead of soldering. This past weekend I replaced my hot water heater (Sooo much more fun than brewing.) Instead of sweating on a new copper pressure release drain tube I used some "Copper-Bond" by The Noble Company at my local hardware store. <$8.00. It's an epoxy that they say is specifically formulated for copper pipe, is intended for hot and cold water service, contains no lead, and "is made from food grade safe resins". It seems to work fine - so far, but it's not being used under pressure. Of course I'm not associated with this company, etc, etc. You can get more info from them via their fax-back number at 1-800-272-1519 or via phone at 616-842-7844.

Date: 15 Oct 95 13:40:47 EDT From: "Richard J. Smith" <72154.516 at compuserve.com> Subject: Wyeast 1056 I recently had a batch go bad during primary fermentation. I was using Wyeast 1056, no starter, just pitched the swollen pack into the cooled wort. Fermentation caught on after 24 hours and went for a week. After fermentation ended I racked to the secondary; I was confounded by the nasty, green apple smell during the racking and almost puked when I stuck my head in the plastc primary. My initial conclusion was, hey, I lost it in my sanitation procedures even though I cut no corners and had no problems before. Well, I tried a little experiment with yeast propagation following Dave Ebert's technique outlined in a recent HBD posting as follows: > >I smack a fresh pack of Wyeast and prepare about 1 gallon of 1.030 >wort that has been highly aerated and supplemented with a good dose >of yeast nutrient. When the yeast pack has swollen properly I pitch >the yeast. Ferment lock in place, I let 'er go for about 10 days. I >carefully rouse the slurry back into solution and siphon the fluid >into 11 12oz bottles. I cap them, label them, and place them in the >fridge. > I tried this using Wyeast 1056; I obtained this from a different retailer than my bad batch yeast. As I was transferring to the bottles after fermenting, there it was again, the green apple, sick smell, a little less putrid but quite noticeable. Both packets of yeast were stamped with a September '95 date, and, in between these two run-ins with Wyeast 1056 I brewed a great batch of beer using a different yeast! Fermentation temperatures were in the proper range each time. I have given a fellow brewer another packet of the same yeast to try propagation at his home completely away from any house bacteria loitering around my brewery. Before the results from this experiment come in, my question for the collective is, Has anyone else had this problem with the September crop of Wyeast 1056? Any other possible explanations out there? Is there a WYeast Labs hot line? Like all my other brewing adventures, I am looking forward to better brewing from this run in. If I can nail down the problem I'll post the solution.

O2 is probably quicker, but I've heard it is possible to OVER aerate using O2. Over aeration isn't really possible using an aquarium pump. Don't know how O2 would affect foaming. Cheers!

You >could also use vegtable oil (might sour?) or lemon oil (might flavor the >wort?) or any food-grade oil. If you're going to use oil, I recommend mineral oil since it's colorless, odorless, doesn't have flavor and won't go rancid. The food grade variety goes for less than $3/pint at your local drug store. The drawback is that it's sold as a oral lubricant (perhaps a good thing), and laxative:^) From what I remember of steam distillations, most, if not all of any oil that gets to the wort for the first couple of batches should get boiled off, as long as it doesn't complex with anything. Remeber that lipids (oils) in your finished brew will be detrimental to head retention. You should probably apply any finish you decide on to preheated wood to open the pores for maximum penetration making it less likely to come out in your mash.

Date: 16 Oct 95 07:57:23 EDT From: Tim Fields <74247.551 at compuserve.com> Subject: Re: Paddle Finish Dion Hollenbeck(hollen at vigra.com) reacts to my comments about oil finishing: >EGADS, oil? Oil will kill the head on beer if it makes it into the >finished product. I would imagine this is not such a good idea. Well, I wouldn't use enough for that to happen - but you have a point I suppose. The idea is to use just enough finish so it is absorbed into the wood. Just a little dab will do yah. Anyway, my preference is for the unfinished approach. I'd just try and get a spoon (or paddle if my tun was large enough) made of dense-grained wood). The concern I have with non-penetrating finishes (like poly or varnish) is that they could flake off eventually.

I found an article on the internet on cask conditioned ales and wrote the author with questions about IPA's, etc. The author is Dr. Gillian Grafton and here is her reply: From: "Dr. Gillian Grafton" <GRAFTONG at novell2.bham.ac.uk> Organization: The University of Birmingham To: Kris Thomas Messenger <kmesseng at slonet.org> Date: Fri, 6 Oct 1995 08:48:01 +0000 Subject: Re: Cask conditioned beer Priority: normal Hi Tom > I under stand > IPA's were shipped to India in barrels; were these oak? lined? > unlined? In the UK cask conditioned beers are mainly dispensed from metal casks, these are either stainless steel or aluminium. The reason is simply cost, they are cheaper than wood casks and it doesn't seem to affect the flavour. That said there are still a large number of brewers and homebrewers who use wood casks, me included. The casks are made from European oak and are unlined. From conversations I've had with other American brewers it seems that the only casks you get in the US are made from American oak. European oak doesn't impart any flavour to the beer which is why the casks are used unlined. American oak however gives the beer a strong oak flavour - I've never tried it but have been told that the flavour can be overpowering. Therefore if you can't get hold of casks made from European oak I would definitely recommend that you use a lined cask. IPA brewers used to ship their beer to India in unlined European oak casks (I don't know where the story arose that they used pitch lined casks - it isn't true!). Hope this helps.

The entry window is open, and stays open to 6 PM on Halloween <;{>. Interested judges and potential stewards should contact Wayne Gisiger, Judge Coordinator at his office (202) 501-2100 x2798, or at home (703) 256-8838. The HC is sanctioned by the American Homebrewers Association (AHA) and recognized by the Beer Judge Competition Program (BJCP). Points for judges and stewards will be reported to both organizations. The judging is closed to the public and only judges, stewards and the agonizing committee will be admitted to the competition site. Once again, the competition will take place at the Hyatt Regency Washington on Capitol Hill in Washington, DC. The ice-breaker beer is planned to be served at 10:00 AM, BoS judging is expected around 2:30 PM. Winners will be announced and ribbons presented immediately after the BoS is over. BTW, the ice-breaker brew this year is an IPA. Stewards should plan on arriving at 9:00 AM, and judges by 9:30 AM. Judges bringing pre-registered entries should arrive at 9:00 to give us time to get the brews into the correct flight. The Hotel is at 400 New Jersey Avenue, NW, just a few blocks from the Union Station Metro. For those driving, 1st St., NW (behind the hotel) has free on-street parking on Saturday. This year, the Dulles Regional Brewing Society has commissioned a well known (to us) artist to create a unique and distinctive design for a commemorative T-shirt. The white Ts have 3-color art work, and feature the capitol (top tilted open with suds spilling out) on the back. Although these are being produced at great expense, they are available for $12.00 apiece in L and XL sizes. If you are not going to be with us in DC, but would like a shirt anyway, send us your size(s), how many and your personal check made out to DReBS to: CDO-HC/T c/o Fred Hardy 13215 Poplar Tree Road Fairfax, VA 22033 We will mail it (them?) postage paid. Note: we can not accept Postal Money Orders - also true for entries. For those who will be participating on the 4th, just bring your cash or check to the event. It would help if you gave me a heads up so we can adjust our order with the supplier. Enter early and often!!!!!!!!!!!!!

I think you may be a little too paranoid. I just completed a test to prove/disprove the theory that RIMS detractors put forth that you cannot get a beer with body from only pale malt because the temp boost from protein rest to sacchrification rest is so slow all starch will be converted at temps favoring Beta amylase and complete fermentability. First batch mashed at 150F second batch at 158F. First batch was dead dry (1.010 after 5 days primary ferment, FG 1.006). Second batch just went to secondary after 8 days and it is only down to 1.023 with tons of residual sweetness and body. FG will not be able to be tested for another 2 weeks, but I doubt if it will get below 1.018. I put my temp controller probe in the wort stream before the heater and the digital temperature readout in the outflow stream from the heater. I have no temp measurement actually in the mash (soon I will have my BruProbeand can take actual mash temps, but not now). I base my system calibration on the fact that if the outflow of the wort from the heater is 158F, the mash will eventually come up to 158F and cannot ever exceed that. As proven by the results of my recent tests, I have complete control over the results without any knowledge of the actual temperature of the mash. I would have to say that more accurate monitoring of the mash temps may aid accuracy, but it does not seem necessary to me. If you adjust your setpoint based on the mash temp, you will *always* get returning wort several degrees hotter than your mash setpoint until equilibrium is reached and I feel that this is not a good plan, especially if you are trying to mash at the upper limits of an enzyme's range. I think limiting the wort outflow temp is much safer, but you do have to deal with the mash lagging behind. Given your results of monitoring temperatures, I will be very interested in monitoring my actual mash temps when I get my BruProbe working and be able to see exactly how far behind the mash lags. dion - -- Dion Hollenbeck (619)597-7080x119 Email: hollen at vigra.com Senior Software Engineer Vigra, Inc.

This question seems to pop up every four or five months, the general consensus is to use ammonia, about 1 1/2 cups in a warm water, overnight, soak in the bathtub will do the trick. The labels will fall off. Beware of the shiny labels. Some labels are shiny and are impervious to water, so the outer layer must be peeled off before soaking. Good luck!

Last I read, about 4 years ago, it was not illegal to sell, but it had to be marked as "not edible" or something like that. A few years before that, it was quite popular as an herbal tea. It turned out to be highly carcinogenic, if memory serves correctly. I used to buy it at a health food store, and one time the jar was marked "not fit for human consumption". (Several other jars were also thusly marked, mostly stuff they geared towards people who were making potpourri, as far as I could tell.) Later, when I went back there, the jar was no longer marked "Not fit..." and I asked, and the guy there said that it was specially processed to remove the toxins. So, it's probably not a great idea to dig up your own sassafras roots unless you can d that processing. I recall it having been something simple, but I really don't remember what that was. I suggest you ask at a health food store. -R Return to table of contents

OK, I might as well, since EVERYONE seems to ask about it. (Apologies if this is misuse of bandwidth.) Literally, that means "Bavarian Beer, More Powerful than Homesickness". No, it's not original from me. I got that on a post card showing a woozy beer swiller, still in the Gasthaus, sipping his (German) suds well past closing time. The beer is so good than it overpowers his need to get home. Likewise, perhaps it's also stronger than my own desire to perhaps one day get back to the States and my much missed weekly brewing, instead of being "stuck here in Bavaria", where difficulty getting supplies and equipment (really!), lots of paperwork, and cheap & good commercial beer all "conspire" to discourage the hobby.
