J." <ajdel at mindspring.com> Subject: diacetyl and Pilsner RE: p.smith's comments on diacetyl and Czech Pils. First, de gustibus non disputandem est but I'd like to point out that many of the Czech Pilsners do have diacetyl at and above threshold level. Pilsner Urquel which many consider to be the definition of Pils certainly does as do Budvar and Eger. These are the ones that I have measured. Doc P will attest that many of the others over there carry it at detectible (by taste) levels as well. Presumably, therefore, the Czech people expect and like this quality in their beers. I know I do. I do not do diacetyl rests for lagers and seem to net about 0.12 - 0.3 mg/L which is about what the commercial Czech products seem to run. This is not an attempt to convince anyone to change his mind. If you don't like diacetyl don't drink Bohemian Pils. I think the German versions generally have it at a lower level but I have not measured any of those. The procedure is a bit of a PITA.

The only time I had a problem was when I had a growler of beer in the carry on. Im also a ham radio operator and had a couple of 2meter handheld radios with me. To protect the whole shebang I had the 2 radios and the growler in the middle of the bag with some sweatpants wrapped around them. I realized at the gate what that was going to look like going through the xray so I told them before it even went in that they were going to want to look at it. Didnt want them thinking it was a bottle full of a nerve agent or napalm with a remote detonator or timing device strapped to it and scrambling the anti terrorist squad. Return to table of contents
Date: Mon, 12 Feb 2001 09:25:38 -0500 From: "Alan Meeker" <ameeker at mail.jhmi.edu> Subject: Another possible source of soot. I too had the problem of soot collecting on the bottom of my brewpot. I use a cast iron ring-style propane burner which worked just fine when I first got it but it gradually developed "yellow-flame disease." I tried adjusting the butterfly air inlet but it had no effect. Then I used a wire brush to clean out the throat but this too had no effect. I finally figured out that the problem was a build up of rust on the /inside/ of the ring, partially obstructing flow. Since it was cast iron there was no problem whacking the heck out of it with a hammer. This liberated a LOT of material from within the ring. I kept banging away at it till this stopped and then was treated to a nice blue flame once again. Till this point I just left my burner attached to the tripod stand outside and, even though I kept it covered with a tarp, apparently enough water vapor from the air was able to get inside and foul things up. Since then I have stored the ring indoors between brew sessions and haven't had a problem. -Alan Meeker Lazy Eight Brewing Baltimore, MD Return to table of contents

I even removed the burner from the stand and put it in a 450' oven for 2 hours. I thought whatever moisture/substance was in it would burn out! WRONG. The culprit was SPIDER WEBS!!! Even if in is only a strand or two, if messes up the flow of the gas. Apparently webs do not burn/melt with even that high of heat! The only reason why I know this is because after all my attempts of fixing the problems, a new regulator, new tubing, even emptying out the tank, having them purge it, and refilling it, I FINALLY went back to little "kid" mentality and just RAMMED a skewer used for kabobs on the grill - ----- down the long metal tube of the burner!!! pulled it out ----JUST A COUPLE OF WEB STRANDS! I thought, no way could such a small amount of webs really mess this up. But when I fired it back up! BINGO!!! it worked like a charm. Good luck and be CAREFUL!!! And by the way, the propane tank was NOT hooked up when trying to fix the problem!!! AGAIN- be careful -- we need to keep as many brewers alive as possible!!! Steve Return to table of contents
Date: Mon, 12 Feb 2001 10:15:14 -0500 From: Kevin White <kwhite at bcpl.net> Subject: Mashout redux David Houseman writes: >Pardon me but I don't understand the logic. One the one hand you say "The >purpose of >high-temperature mash-out is to fix the wort carbohydrate profile by >stopping all enzyme activity (hence the high temperature)." On the other you >say "Enzyme activity will >continue in the brewpot until the wort temperature reaches 185F or so, >giving you a bit more fermentables." I apologize for not writing clearly. First, what is "mashout?" In the brewing industry, mashout is the process of pumping the mash from the mash tun to the lauter tun. Since most homebrewers use a combination mash/lauter tun, I'm uncertain how to define it for homebrewing, and perhaps this uncertainty helped confuse my earlier post. For purposes of this discussion, let's define "mashout" as whatever the homebrewer does at the end of the mashing procedure but before draining wort into the brewkettle. What I meant to convey in my earlier post is that if you are not concerned about the carbohydrate profile of your wort changing slightly from the end of your mashing procedure to the start of the kettle boil, then there is no need for a high-temperature mashout ("high temperature" being high enough to denature the amylase emzymes, >185F). If you do not denature the amylase enzymes at the end of your mashing procedure, then some amylase activity will continue during lautering and in the brewkettle until the wort temperature reaches amylase denaturation temperatures. Thus, _not_ using a high-temp mashout slightly raises the fermentables fraction in your wort. If you wish to establish a certain wort carbohydrate profile during the mash procedure and prevent it from changing, then you can "lock in" or "fix" the profile by raising the mash temperature high enough to denature the amylases. Enzyme denaturation is permanent; once denatured, enzymes do not "recover" at lower temperatures, so the carbohydarate profile of your wort will not change from enzyme activity. > >Since mashouts are typically performed in the 168oF-172oF range, and all >activity doesn't stop until about 185oF, then mashing out doesn't stop all >enzyme activity. > You are correct that lower temperatures do not denature all amylase enzymes. But, keep in mind that mashout temperature is selectable by the brewer depending on results desired. Mashout temperature can be whatever YOU want it to be, and that depends on what effect, if any, you want it to have on your wort. I hope this is a clearer explanation. ******************** Stephen Alexander writes: > >Mashout releases an extra 3-5% extract (more with less well modified malt) >much of which ends up as unfermentable dextrins.

(Malting and Brewing Science, Vol 1, pgs 264-265 [Chapman and Hall, London]) list 167F to 170F as the amylase inactivation temperature. Kunze (Technology Brewing and Malting, pg 193 [VLB Berlin]) lists alpha amylase inactivation temperature as 176F and beta amylase at 158F. You may be referring to the _initial temperature_ of mashing water. Mash water initial temperatures at these levels quickly drop as the room-temperature grist is added to the mash tun. Properly implemented, the stabilization temperature is at or just below the first desired conversion rest temperature, which is well below the amylase inactivation temperatures. I doubt that any significant starch conversion can occur at temperatures at or above 176F. Kevin White Return to table of contents

I have dry hopped a few times and once with plug hops loose in the carboy. I got the same feeling of under utilization of the hops because they weren't completely in the beer, floating on top. In the recent past I have used a stainless steel kitchen knife in the hop bag and that had worked out fine. I had no problems at bottling time with the loose leaf hops (FYI: I rack from the secondary to a bottling bucket then to bottles). I did get a few small pieces to stick in the foot of the racking cane, but I didn't notice until I was near the end of the racking. I think they may have served as somewhat of a filter. Good luck.

Does anyone know if Wyeast has an equivalent? Back in 1994, Dan McConnell, owner of Yeast Culture Kit co., which produced the YeastLab liquid yeasts, posted to HBD the identities of YeastLab yeasts. A03 London was White Shield. Since Worthington (part of Bass) White Shield is a classic, bottle conditioned pale ale from Burton-on-Trent, it is not really a London strain. Who knows why it acquired that name. I should ask Dan some time. Although YeastLab liquid yeasts are no longer produced, you can get slants from YCKC. Growing up yeast from a slant is not that much more trouble than using a tube. The posted IDs of Wyeast do not show White Shield as the origin of any of their yeasts, but one may be the same with a different name.

Date: Mon, 12 Feb 2001 10:01:25 -0600 From: Nathan Kanous <nlkanous at pharmacy.wisc.edu> Subject: Diacetyl and Czech Pilsners Mr. Smith and everyone else, In my readings and understandings, diacetyl is, in fact, a significant component of the flavor of Czech Pilsners. I can't quote a source right off hand. There have even been discussions in past years on the Homebrewers Digest that some folks have worked diligently to convince the brewing world that diacetly and DMS are both glaring faults in lager beers. I, personally, disagree. I'll dig around a bit and see what I can find, but I'm firm in my commitment that diacetyl is a classic feature of Czech Pilsners. From Pete Ensmingers article in Brewing Techniques: http://www.brewingtechniques.com/library/backissues/issue5.3/urquell.html Profile of a Classic Beer The final product has a bitterness level of about 40 IBUs and a nicely balanced aroma of Saaz and malt. Despite the relatively high IBUs, Pilsner Urquell impresses most beer aficionados as having a very soft and malty taste, no doubt the result of soft water and triple-decoction mashing, both of which emphasize malt character in finished beers. The original gravity of the export is about 12 deg P (1.048 S.G.), with a final gravity of 3.8 deg P (1.015 S.G.), and an alcohol content of 4.4% (v/v) (18). The brewery also produces 10 deg P (1.040 S.G.) beer to appeal to the increasingly lighter Czech tastes (17,19). Pilsner Urquell's flavor profile includes some diacetyl notes, detectable to some beer drinkers as a buttery flavor. The brewery claims the maximum allowable level is 0.12 ppm, a bit on the high side, but probably due to the beer's incomplete fermentation. Few, however, seem to find the flavor objectionable (9). Some would even say that it enhances the beer by giving it added complexity. From the BJCP Guidelines: 2A. Bohemian Pilsner Aroma: Rich with a complex malt and a spicy, floral, Saaz hop bouquet. Moderate diacetyl acceptable. Appearance: Light gold to deep copper-gold, clear, with a dense, creamy white head. Flavor: Rich, complex maltiness combined with pronounced soft, rounded bitterness and flavor from Saaz hops. Moderate diacetyl acceptable. Bitterness is prominent but never harsh, and does not linger: The aftertaste is balanced between malt and hops. Clean, no fruitiness or esters. Mouthfeel: Medium-bodied, medium carbonation. Overall Impression: Crisp, complex and well-rounded yet refreshing. History: First brewed in 1842, this style was the original clear, light-colored beer. Comments: Uses Moravian malted barley and a decoction mash for rich, malt character. Saaz hops and low sulfate, low carbonate water provide a distinctively soft, rounded hop profile. Ingredients: Low sulfate and low carbonate water, Saaz hops, Moravian malted barley. Vital Statistics: OG: 1.044-1.056 IBUs: 35-45 FG: 1.013-1.017 nathan in madison, wi Return to table of contents
Date: Mon, 12 Feb 2001 10:03:46 -0600 From: Brian Lundeen <blundeen at rrc.mb.ca> Subject: RE: fermentability of first runnings Stephen Alexander writes: > Once corrected for gravity it > becomes clear that > there are more fermentables and maltose per unit extract in > first runnings > than latter runnings. Not only does mashout decrease fermentability > slightly but sparging does too. Do you have any numbers for how much more fermentable the wort is? As in, you could expect on average your wort's terminal gravity to be X points lower or expect your AA to be Y percentage points higher. I don't sparge, or batch sparge very lightly, and I wonder if this makes enough of a difference for me to be achieving TG's in the 1.006-1.010 range a lot of the time even with mash temps in the 66C-68C range. Also, it has been written that no-sparge brews tend to be "maltier". I have always took this to mean a higher terminal gravity. Are the two not related? So many questions, so little time. BTW, somebody suggested my thermometer may be inaccurate, so I checked it against a good mercury thermometer that I borrowed from the Chem dept at work. My thermometer consistently read 0.3-0.5C high (which is good to know) but I don't think that is enough to account for my low gravities. My hydrometer accuracy remains unknown, and I do have another hydrometer, but it reads only in Brix (specifically -5 to +5). How much is each Brix degree in gravity points?

Date: Mon, 12 Feb 2001 11:37:11 -0500 From: "Nathaniel P. Lansing" <delbrew at compuserve.com> Subject: re:sooty burners What everyone has said about properly adjusting the air-shutters on a gas burner is true. Though on most high output burners the design is such that at reduced output (throttled down) the velocity of the incoming gas doesn't create the needed turbulence to thoroughly mix the gas/air mixture before it emerges and is burnt. A poor mixture leads to soot. This is more prevalent in the jet burner type vs the ring burner type. The jet has virtually no mixing chamber and soots profusely when throttled down, a ring burner has a little more of a mixing path before the gas emerges creating somewhat less soot. The bottom line is 170K BTU is more heat than you can keep under a 10 gallon kettle and when throttled back you get a little soot. As someone mentioned the big problem here is carbon monoxide if you are brewing indoors. The soot is just a pain in the butt to clean up. N.P. Lansing Return to table of contents
Date: Mon, 12 Feb 2001 11:48:57 -0600 From: p.smith at gooseisland.com Subject: Re: Diacetyl and Czech Pilsners Nathan Kanous took me to task for finding diacetyl to be a fault in Czech pilsners. Indeed, I was wrong, at least according to the BJCP. It's simply not my taste. It is not universally accepted that diacetyl is a proper pilsner profile. Most lager strains, and most procedures, are devoted to its reduction. See: http://brewingtechniques.com/library/backissues/issue1.2/fix.html http://brewingtechniques.com/library/backissues/issue2.1/miller.html In addition, see the World Beer Cup guidelines: 15. German-Style Pilsener A classic German Pilsener is very light straw or golden in color and well hopped. Hop bitterness is high. Noble-type hop aroma and flavor are moderate and quite obvious. It is a well-attenuated, medium-bodied beer, but a malty residual sweetness can be perceived in aroma and flavor. Fruity esters and diacetyl should not be perceived. There should be no chill haze. Its head should be dense and rich. 16. Bohemian-Style Pilsener "Bohemian Pilseners are slightly more medium bodied, and their color can be as dark as light amber. This style balances moderate bitterness and noble-type hop aroma and flavor with a malty, slightly sweet, medium body. Diacetyl may be perceived in very low amounts. There should be no chill haze. Its head should be dense and rich." In truth, since PU has moved from older, wood fermentation vats to cylindro-conicals, I wouldn't be surprised if we find "very low" amounts to be reduced to sub-threshold values in this paragon of Bohemian pilsners, and since it "defined the definition" in the first place, I'll bet diacetyl will be eventually removed all together from style definitions. In "very low amounts," I have found that it is at times difficult to distinguish "butter" from other flavor components - chiefly maltiness, in syncretic combination with other characteristics such as "estery" and the sensation "mouthfeel." However, ultimately I don't care. I just happen to not care for diacetyl in my pilsners, personally find it to be a fault, and so take steps to avoid it - a solid diacetyl rest and thorough sampling/micro. elimination.

Date: Mon, 12 Feb 2001 13:20:40 -0500 From: "Houseman, David L" <David.Houseman at unisys.com> Subject: RE: Diacetyl and Czech Pilsners. Yes, diacetyl is a flavor component of the Bohemian Pilsner style at up to moderate levels. It is the only lager style where diacetyl is acceptable. The yeast employed and the fermentation processes used results in noticeable presence of diacetyl. It goes well with the other characteristics of the beer, IMHO.

Date: Mon, 12 Feb 2001 13:25:28 -0500 From: "H. Dowda" <hdowda at axs2k.net> Subject: Soot; Ovens and Bottles; Wyeast 2000. I am sure everyone knows this, but, an old Boy Scout trick is to coat the bottoms of pots to be used over propane with a liquid detergent, prior to placing the pot on the fire. Any should work, but intuitively it seems the 'clear' types may be better. Of course this doesn't fix the real problem, fixing the burner, but makes clean-up easier. The recent posts about sanitizing bottles (and other heat resistant materials) with dry heat (aka in the oven) are right on. If fact, dry heat used for 2 hours after the material being heated has reached 350 F (180 C) will not only sanitize, but will sterilize (references on request). It should be noted that many, if not most, home ovens do not maintain the thermostats temps, but vary within a range, sometimes being five to ten degrees less than posted. 285 F (140 C) for three hours will also do the trick. This all assumes you want to kill any sporeformers in your bottles, however most sanitizers do not do that anyway. 350 for 2 hr. works well for me and I do not worry about the temp fluctuations. My Wyeast 2000 RFI resulted in some interesting posts and one suggestion that I, perhaps, did not know how to use a smak-pak. First, thanks to all who shared their experiences with this yeast. Several people responded to say that they, too, were concerned at the lack of krauzen in the starters (for those who made them) or in the fermentor. As I had noted, in the starter, the production of CO2 was not abated, only the foam. This occurred in my fermentor also. A couple of folks also noted this. However, when new wort was pitched on the cake the foam was rapid and massive. I noted an odd smell in my starter (emesis, that's puke to some) which was not commented upon by anyone, except the great chemist, brewer and ginger ale aficionado from the far north, resulting in my methylating a bit and shooting it through the old gas liquid chromatograph. The culprits were likely butyric and iso-butyric acid. I suppose from something in the starter..(huummm, the cat was mucking about the pot before I put the wort in the bottles, maybe a little fleur de hair ball, what). As expected the yeast made a lovely pilsener. Return to table of contents

It was great for five gallon batches, but now that I'm brewing 10-15 gallon batches (I've been doing joint brew sessions with some beginner friends of mine), it seems a little anemic. How can I increase the output? Should I drill out the oriface? Anything else? Just a little more power . . . . Also, I've been selling some 3 gallon cornelius kegs on eBay. A few ( 2 or three out of 100) have come back with lids that just didn't seem to seal, although they don't look bent or warped. Is there different style lids, or are they more-or-less universal. I have been pairing lids that say "Firestone" on top with the pin-lock kegs - I assume this is correct?

Has anybody tried it and what kind of gadget did you use. I have also heard that the malt should be wetted out slightly before smoking it. What kind of wood is suitable and what sort of time intervals are we talking about. Thanks! SKAAL! Jens Jens P.

Date: Mon, 12 Feb 2001 11:53:37 -0700 From: Matthew t Marino <mattncherie at juno.com> Subject: Draft Coils I want to construct a cooling coil for my draft system, I dont have or want an extra fridge and I figured a coil about 25 feet or so would do the job. My question is will copper(cant afford stainless) contaminate the beer during the time it is sitting in the coil say overnight or after a couple days. Should I discard the first pint or so after it has sat? That seems like a waste considering i will only pull a couple pints a day or so. Any suggestions or warnings? I have about 25 feet of 3/8 copper tubing from an old immersion chiller I wanted to use for the draft coil. I was wondering what would be best to really clean the inside I have access to caustic and acid cleaners but was wondering how they would react with the copper. Any advice would be appreciated.

However just in case anyone still has a problem with soot after taking the advice, one thing you can to at least make the problem easier to deal with is use soap. Take a bar of bath soap and rub this all over the bottom of your kettle. Only on the OUTSIDE (for the newbies). When you're finished brewing the soap and soot wash off easily.

Palm Pilot Version Someone asked about converting the HTML Digest to Pilot Doc format using the link at the bottom of the HTML page. With a little futzing around I managed to make this work - as the page link doesn't work correctly. Simply place the link below into your browser address window and "Go". In a few seconds a download window should appear. Confirm your download intention and a Homebrew_Digest.prc file will download. You can then upload this into your Pilot and read it using Aportis Doc (or compatible). Overall it seems like a klutzy way. Here goes... http://pilot.screwdriver.net/convert.cgi?url=http%3A%2F%2Fhbd.org%2Fhbd%2FCu rrentHBD.html&title=Homebrew+Digest This should all fit on one line ! [ENABLE JANITOR ALERT] Pat - if you replace the http address (<a href=http://pilot.screwdriver.net/2doc.cgi>) on the HTML page and use the one above - I'd venture an ill-educated guess, that the link would work as intended. [DISABLE JANITOR ALERT] Someone else suggested using AvantGo... an excellent suggestion... but for some reason AvantGo reports the file (http://hbd.org/hbd/CurrentHBD.html) as too large to download (YMMV) - even with a download cap at 500k. I'm still trying to find a solution. If anyone has a AvantGo link that works - please post it. Cheers! Bob Fruit Fly Brewhaus Yesterdays' Technology Today Return to table of contents
Date: Tue, 13 Feb 2001 04:05:32 -0000 From: "Bret Mayden" <brmayden at hotmail.com> Subject: Mashout Again Steven Alexander writes: "Nah - You can get complete conversion of malt with mash-IN temps of80C(=176F) and almost so at 85C(=185F) !! These temps aren't enough to shut-down alpha-amylase before conversion completes, and that's the point of a mashout." Question: I thought that mash-out is supposed to stop enzyme activity & make the sugars easier to extract from the grist. If enzyme activity continues at 176-185F, then what is the point of mash out?
