---------------------------------------------------------------------- Date: Tue, 26 Feb 2002 04:58:25 -0500 From: "Steve Alexander" <steve-alexander at worldnet.att.net> Subject: home malting and some guesses about millet A traditional malting process for barley is described at ... http://hbd.org/brewery/library/Malt.html I've malted barley and oats and it's necessary to pay close attention to bacterial and yeast which inhabit all grains. Some sources suggest the use of limed water for the first soak to reduce the bacteria. I've always used chlorinated tap water for the soaks and rinses too - perhaps that helps. Malting in a cool location with low humidity and some air flow should help prevent fungal attacks. You may need to add a very tiny amount of soap during the initial soak to reduce surface tension to get the millet wetted. I've performed barley soaks in 5gal plastic buckets and couching and rests on screened frames supported off the floor. If you have an old zapap you can drain the soaked barley and weight it easily to determine when to stop the soakings (abt 45% increase in weight). You'll need a finer screens for millet and I have no clue about the %water needed. My hunch is that the way wetted millet clings together when wet that bacterial infection may be a problem, and 'turning' to expose to air may be very difficult. Even after the water accumulation is sufficient for malting, a quick dip (several minutes) in fresh running water can help remove some of the bacterial load. Access to air is necessary for barley and wheat malting but some wetland grains like rice are capable of fully developing beta-amylase without air.. I don't know about millet. Unless you can find out I'd plan on some aerated floor/screen malting period despite difficulties. Turn the malt regularly - lets air access all the grain, evens out the temps (it gets warm in the middle of the growing mass), helps drainage of excess water and breaks up the rootlet tangle. Barley rootlets *will* intertwine leaving you with a big thick barley carpet if you ignore turning at the wrong time. No clue about how far millet should go - but to be practical, you shouldn't let the endosperm reduce very much in size - 10-15% is OK. Acrospire length is a 'good enough' measure of development for barley, *but* it's very easy to let the malt over develop which detracts very seriously from the final malt mass. Barley develops most of it's enzymes fairly early and the more extended malting period helps degrade the protein and beta glucans. If you'd be happy with a less modified type malt then you are better off not trying to hit the very fine line between 'full' and 'over' modification. I think you'll need to try a few small scale kitchen malting experiments on millet. Try different soak schedules till you get good development without the grain going mushy. Also use a magnifier and a razor blade (and iodine stain if needed) to examine endosperm depletion. This should give you some idea about soaks, %water needed and the malting germination period. Millet *may* malt much faster than barley. Drying - zippered cotton pillow cases partially filled with finished wet malt in a laundry dryer is a decent method - fairly effective. *DO* use a safety pin to prevent the zipper from opening. You can also create something like 'wind malt' by drying the malt on a screen , a small room with a dehumidifier and fan, turning frequently. In the dryer the culms(rootlets) come off on their own. In the oven or on a screen culm removal requires some hand rubbing or place them in a sack and beat. The culms have a rather unpleasant odor and should be removed from the malt. Warm air drying would probably be ideal. To store the malt for any significant period of time you need to drop the moisture level quite low <5% - 'hand dry' isn't good enough. You can evaluate the moisture level by weighing a small sample before and after baking out in the oven. It's difficult to get malt this dry using 'wind malt' methods. Until you do get the malt very dry it may retain certain grassy flavors that aren't very attractive and also be subject to fungal attacks. I have a new oven with a 100F proofing temp setting and a 140F dehydrating/convection setting and the temp seems quite stable. I'll probably try this for malt drying, *BUT* be aware that most ovens will have huge temperature variation and can't be used for malting without thermally buffering the malt in a pot - which won't permit convenient drying. You'll find some other good articles on crystal and Munich malt at the site above. I find that a crock-pot set on high does a good job of temp control for modifying crystal prior to kilning. - -- I'd suggest you try making a brew or two with 15-20% unmalted millet to see if you like that part of the flavor, The malt will probably be better in a beer, but if you don't like the predominant contributions unmalted, malting won't solve that problem. You *may* find information on malting millet or other tiny grains by looking up a book with a title - "Industrialization of indigenous fermented foods". Some very interesting topics in this book. -S Return to table of contents

Date: Tue, 26 Feb 2002 07:56:25 -0500 From: "Peter Fantasia" <fantasiapeter at hotmail.com> Subject: Weizen yeast Luke is having some problems with final gravity using 3068 Weihenstephan weizen yeast. Your terminal gravity of 1.018 sounds like an extract problem. If the extract is high in dextrins no amount of yeast can lower the gravity beyond a given point. You might try using a dry wheat malt extract if you can find it. Munton makes one that is 55% barley and 45% wheat. The dry extracts will also give you a lighter color which will be more to style. I've also had good luck with Breiss dry wheat malt extract. I've used 3068 with both the above dry malts as well as all grain and the final gravity was 1.008 - 1.010. You might also try leaving it a little longer in secondary and even "rouse" the yeast to ensure all fermentables have been consumed. On another note a yeast that I've had very good results with and that often get's ignored or badmouthed is Wyeast 3056. It is a mixed strain. You can see in previous posts Schneider Weiss uses a mixed strain. Good luck and keep us posted, Pete "the madwheatman" Fantasia Return to table of contents

Since I will just happen to be in Munich during Starkbierfest, I would like to sample a few of this season's doppelbocks. (By "a few" I of course mean as many as time allows.) My Google search turned up tons of hits on Starkbierfest, almost all of which are in German (big surprise). Could somebody point me to an English-language source for the various breweries' Starkbierfest schedules? Also, I think I can figure out Vienna and Prague, but where should I go for local brews and beer culture in Budapest? Thanks in advance.

My two and only experiences with making wheat beers from extract have been bad ones. In both cases I suspect that the chief problem was excessively old extract. My first wheat beer was 23L from 3.0 kg Briess extract, OG 1.038 or so, and Cooper's dry ale yeast. This beer was quite dark, and had an FG of about 1.020. Also, the taste was all wrong, the closest I can describe it is "molasses-ey". Is this what people mean when they refer to "the old-extract 'tang' taste"? (The yeast wasn't pooped out, FWIW - I added some boiled corn sugar and water to the 1.020-and-not-dropping beer, which would have made the OG 1.048. This happily fermented out, leaving my FG at 1.020....argh!) Last August I brewed what I meant to be a pale ale from extract. I used two 1.5 kg cans of Cooper's light malt extract plus about half a can (already opened) of Cooper's wheat malt extract - or so I thought. One of the cans that I *thought* was light LME was in fact a wheat extract - so in fact I used 1.5 cans of wheat plus 1 can of light LME. Yeast was Cooper's, OG was 1.054. This batch turned out very similarly (poorly!). It's FG was 1.020, it was very very dark (perhaps the colour of a Midlands mild, or a Newcastle Brown?), and that yucky "molasses-ey tang" was right there. FWIW the wheat malt extract cans had their end slightly bulged (yeah, now I know better!). I kegged it anyhow and set it aside, figuring it might get better someday. In fact I tasted it this morning, because I'm in the process of triaging (read: sewering) my kegs of bad or second-rate beer, as I'm brewing good beer these days and am running out of available kegs. Still tastes the same. Looks brilliantly clear, colour is the same, FG is still 1.020. Now I need to quickly find an application for 18 litres or so of this beer, or down the drain it goes too (perhaps some sort of American-type barbeque sauce?) The only other wheat beer I made was from a Brewhouse wort kit (15 litres of concentrated wort, dilute to 23 litres), and Wyeast 3068. It worked brilliantly, the beer that it made was very much a correct Hefeweizen. In fact I bought six bottles of fresh (? - expiry date July 2002) Paulaner Hefe-weissbier last week (suddenly turned up in New Brunswick provincial liquor stores), and I'm now even more pleased with how "my" Brewhouse beer (kit) came out last summer (interestingly, that beer kept very well - last month we had some bottles of it, which would have been 8-9 months old, and they were still very good - I thought wheat beers were supposed to age badly). > So, can anyone guess as to what I am doing wrong?

I expect that there is not a problem with the 3068, your water or your fermentation temp - I had exactly the same problems as you did (too dark, high FG, and wrong taste). As for the 3068 fermentation, recent posts here suggest that it takes a long time to finish. Mine was quick, but a friend using the same yeast (I pitched my batch with his dregs) in an all-grain batch experienced a vigourous primary ferment, but a very long (2-3 weeks) and active secondary (continuous visible bubble production in beer) ferment. > Sorry for so many questions, but I love my wheat beer, I dont > have the time to do a full mash, but I wanted a nice summer > drinking beer that was around 1.010. I'm really interested in how your second batch turns out. I'm curious whether we encountered an intrinsic problem with wheat extracts (you just can't make a good tasting light coloured wheat beer from extract), or if we simply discovered that you must positively use very fresh extract. Please report your results, whichever way they go! (Hmmm, just before sending this I thought I'd go and get the date codes from the cans of Cooper's extract that I used. I brewed in August 2001. The light malt extract says "08:29 BEST BEFORE 21 06 01", which I assume is 21-June-2001 - so it was a bit past the expiry date, though I have no idea how old this means it was. The can was not bulged at its and, and neither is its unopened sister can that is sitting here in front of me. The wheat extract is marked a bit differently, is says "07:08 USE BY 10 02 20", which I can't reasonably decode. The can ends were bulged at the time that I made the beer) Separately, let me thank the several HBD members who helped me with an earlier question I had about why homebrew doesn't taste good when fresh, and improves after several months aging, whereas microbrewery beer is good for drinking in ten days (the consensus seemed to be "underpitching by homewbrewers). I've finally, *finally* gotten a large and healthy enough yeast population going, and my last batch of "Maris Otter Blonde Ale" (1.048) pitched onto the dregs of a Best Bitter (1.042) actually had a real live yeast cake pancake on top of the beer, just like a real brewery! Next stop, 1.062 IPA...... I think I've settled on brewing a Sister Star of The Sun, can anyone recommend a preferred IPA?

I'd like to see the whole thing. Some of the results seem a bit puzzling to me.

Date: Tue, 26 Feb 2002 09:12:03 -0800 (PST) From: David Passaretti <dpassaretti at yahoo.com> Subject: re:finishing welds I use a similar sanke/corny fermenter and also have some rough welds on the inside. While you could go through alot of trouble to smooth them out my rec would be to leave them alone and not worry about it. For starters, for most 10-12 gallon batches the fermenting wort, even with a large krausen will never come into contact with the weld so the risk is minimal. Second, the best way to sanitize these fermenters is with heat. There are two methods, both of which I have tried and used for several years without any infection problems. Either put one quart of water in the bottom and with the top loosley hanging in the fermenter, boil (on a propane burner) for 15-20min. A little more effettive I think, Is to close the top of the fermenter and place a pressure guage on the gas out side. Then heat to 15-20psi and hold for 20 min. This will kill all bugs without worry about rough welds or 15 galllons of sanitizer. Return to table of contents
Date: Tue, 26 Feb 2002 09:24:12 -0800 From: "Kraus,Drew" <drew.kraus at gartner.com> Subject: Servomyces experiment results (long) Well, it's about time I got back to the collective regarding the results of my little Servomyces experiment. As a reminder, I'd read some glowing reviews regarding Servomyces (a yeast nutrient currently being marketed only to commercial brewers by White Labs - NAYYY - check out http://www.yeastbank.com/features/servo.htm), and after managing to get my mitts on some, I wanted to see just what effect it has on the fermentation process and final product. First of all, I'd like to thank those who responded to my question regarding how to control for yeast-pitching differences (controlling for variation between yeast batches and size of pitch). Opinions varied, and in the end I followed the advice of a number of you, including Dr. Chris White at White Labs, and used separate pitchable vials of the same strain (California Ale - WLP001) bearing the same batch number. Beyond that, my plan was to mash-up a 10-gallon batch of IPA (may have been better choices for the 'spurriment, but I wanted an IPA on tap, soooo...) then split it in half; boiling, hopping, cooling and pitching each sub-batch consistently, with the only planned variation being the addition of a dose of Servomyces added to the last 10 minutes of the boil of the second batch. Now, I should note that the 10-gram packet of Servomyces that I was using is enough to supply a 10-barrel batch of beer. As I figure it, I should be able to do about 30 10-gallon batches with that. Herein lies the first variable. Not knowing anyone who would have a scale accurate enough to measure out one-third of a gram (if you know what I mean... and I think you do), I followed the advice of Bob Sheck and eye-balled it, following his description of "no more than can be gathered on the blade of a jeweler's screwdriver." The good news is that White Labs hopes to have a homebrewer's version of Servomyces on the market soon. I brewed, cooled and pitched both batches. As I'm still getting used to my new brewing system, I ended up with closer to 8 gallons of 1.062 wort, rather than the 10 gallons I'd been shooting for. Oh well. I chose not to aerate, as I felt that it would be difficult to be consistent between batches. Among the things that I noticed with fermentation (in glass carboys) were: 1) the Servomyces batch began showing signs of fermentation in about 8 hours, whereas the "control" batch took about 20 hours. b) the krausen on the Servomyces batch was consistently about twice as high as on the control (if there was half an inch on the Servo batch, there was a quarter-inch on the control... at high krausen, there was about 3 inches atop the Servo batch and (you guessed it) about 1.5 inches on the control) iii) just watching the activity in the wort, the Servo batch seemed to have a more active "churn" going, but I have no idea how to measure or even describe the difference... perhaps there's a standard "snow globe" measurement out there someone can point me to ... here's where thing got a little, umm, "interesting" with the process. See, I hadn't counted on San Jose's cold snap happening right around then. Cheap such-and-such that I am, even in the name of brewing pseudo-science I'm not going to heat my apartment at night or while I'm away at work or out of town. That meant that the room temps in the ol' fermentation closet would drop to around 55 degrees F for much of the day. Hearty as WLP001 can be, this was a bit much to ask. The Servo batch slowed to a crawl (although still able to lift the cap on the airlock) at a gravity reading of 1.018. The control batch pooped-out all together (no airlock liftage) at a reading of 1.024. Tried rousting them, no luck. Set up the old "desk lamp incubator" in the fermentation closet... still no luck. Finally, I gave in, and still trying to keep things as consistent-ish, I split one more vial of WLP001 (screw it, I eyeballed it this time!) between the two. Turns out the weather started warming a little in San Jose around that time too, and with the desk lamp incubator doing its finest, the brew closet temps were closer to 62 degrees F. Fermentation activity perked up... and there was much rejoicing. I gave them another 2 weeks to finish off, and both did so. The Servo batch finished at 1.010. The control batch finished at 1.013. I kegged both batches, carbonated at 12 PSI for a few days and started serving (at long last!). I imagine that the differences in the end product are directly attributable to the FG difference. As an apprentice judge some observations worthy of note were: A) both batches settled well, although I wouldn't give either the "clean & bright" visual description I've judged on some beers **) there was a more pronounced hop aroma to the Servo batch, both highlighted the caramel malt sweetness present in the recipe III) the Servo batch had more pronounced hop bitterness and flavor, while the control batch had a more "rounded" and smoother balance iv) there was a bigger, softer mouthfeel to the control batch 5) "January 32nd - The Servomyces batch announced its presence with authority. The caramel sweetness set out in a frenzied dance across the palate, chased feverently by a never-tiring and ultimately triumphant hops bitterness spurred on by a well-carbonated, but not "fizzy" mouthfeel. The flavor of the Cascade hops didn't bother to wait for even the first sip to commence, choosing instead to march right in with the aroma and set up shop in the imbiber's quaffing experience, eventually sharing, though never conceding territory to the malt sweetness at mid-glass, whilst a mild alcohol charge kept the pot ever-stirring. Jan 33rd - The Control batch matched the aggressive hops "yin" with a warm, friendly malt "yang". Rivulets of hops flavor "cascaded" across the tongue, playfully teasing the caramel malt undertones at mid-sip. By sip's end, said malt undertones had had just about enough of that and filed a complaint with the IOC alleging tainted scoring by the west coast judge. The IOC, being in Utah, washed it's hands of the controversy stating that it had no authority to mediate given that the contentious liquid's alcohol levels exceeded local statutes anyhoo. By mid-pint, however, the alcohol undertow began to exude it's cheerful warmth, and working hand-in-hand with a sturdy mouthfeel, peace and harmony reigned throughout the palate." (Please note that the above judge failed to sign his score sheet, scrawling only the initials "BK") For what it's worth, those were my observations. Feel free to ask questions either directly to me or on the open forum. Brew on! Drew Kraus San Jose, CA (Rennerian-challenged) Return to table of contents

Historically, the main problem with dried lager yeasts has been that there just aren't that many. For reasons that are not fully understood, lager strains don't hold up as well during the drying process. A lot of work has gone into getting around this problem but, one need only to look over the lists of available dry yeast strains to see that this problem remains largely unsolved.

I have an upright freezer with an external temperature controller. I've been using it for fermenting and for storing full cornies. It occured to me (not long before I purchased it) that I could also put a couple taps through the door and keep a constant supply of homebrew at my finger tips. I have since installed one tap and am waiting for the second to arrive. Installing the tap through the door was easy given the ready made stock of shanks and taps available at every HB store. After installing it, I excitedly crammed two Cornies of fermenting bock (a split batch using Wyeast 2206 and 2278, I like the 2278) and one Cornie of carbonated water into the box. My CO2 tank just barely fit in the corner. I quickly became aware that keeping the CO2 tank inside the box takes up too much space, is hard to adjust and a real pain if I want to turn the gas off and disconnect it after a "session". The reason for disconnecting is that I found my tank empties faster than it should when it's always on. I suppose the gas is escaping through a slightly loose connection or through the gas line itself. So, I would now like to keep the CO2 tank outside the freezer and run a line through the door. Ideally I would be able to disconnect the line from both sides of the door as opposed to having a long piece of hose protruding from the door. The solution I concocted in my head was to run a piece of threaded pipe through the door and attach a gas-in keg plug to each end. This would enable me to easily attach/detach both the quick disconnect from my CO2 tank on the outside, and the door-to-keg hose on the inside. The problem I've run into is that I can't seem to find a threaded pipe the same size as the keg plug. I went to the hardware store and ended up with a half measure consisting of a 1/4-inch x 3-inch threaded pipe and two 1/4-inch Barb to FIP adapters. Using these would keep me from easily disconnecting the hose from the door due to the fact that the hose would be clamped onto the barb in the door. I'm hoping that someone knows the thread size and/or where I could locate a threaded pipe of the same size as my ball-lock Cornie-keg gas-in plug. Alternatively, maybe someone could point out a beter way to run CO2 into the freezer from the outside. Thanks, Doug Hurst Chicago, IL Return to table of contents
Date: Tue, 26 Feb 2002 22:45:58 -0500 From: "Greg Collins" <gmc at setel.com> Subject: Mash PH/ Water Analysis Greetings: I am looking for the cause of an extreme bitterness that develops in my higher gravity beers (1.055). This strange uninvited phenomenon seems to invite itself as the grain bill darkens. The PH of my mash is always on the low side around 4.9 using Pale 2 row base malts with no more than 5 or 6% dark grains (Crystal 60). Even at that rate I still have problems hitting that 5.1~ 5.3 target that is so important, or is it? Will a few 1/10's make that big of a difference? Here is a fresh analysis of the mineral content of my water to go along with the above. It's amazing what those guys will do at the water company if you tell them why you need it... :] Do I need to do anything far as my water is concerned? PH = 7.0 Hardness = 79 Calcium = 24.6 ppm Bicarbs = 41 ppm Sodium = 10.62 ppm Chloride = 23.1 ppm Sulfate = 21.7 ppm Magnesium = ? (too little to fuss with he said) TIA Cheers!! gmc Appalachian Mountains Eastern, KY Return to table of contents
