My lone foray into brown malt use is hardly enough to determine what my own limits are, let alone yours. I suspect, given my preferences for more caramel, less roasty in brews of this nature, that I probably would not want to pursue any experiments in high percentage brown malt use. I generally take the approach, which is likely to produce something that I will find undrinkable? Too much or too little? With me, it's usually too much. Others who really enjoy extremes could take the opposite tack. Brewer, know thyself, and listen to your inner voice for guidance. ;-) Cheers Brian Return to table of contents

It works very well for storing grain. This is how I do it: Place the grain in a container that can be sealed. Get some "dry ice" (compressed CO2) from an ice cream vendor. They use it in those cooler boxes at the beach, games, etc. Place a small piece of dry ice on top of the grain. (I use about half a cup of dry ice on 100 pounds of grain in a 25 gallon drum). Place the lid on, but do not tighten - leave space for the gas to escape. The dry ice dissolves, giving off CO2, which is heavier than air, and therefore settles between the grain, pushing out the air. When it is finished dissolving, close the lid tightly. No oxygen for beetles to hatch. I haven't had any problems with grain beetles since I started using this method years ago. I have found that the grain stays clean with only one "charge" of CO2. Just make sure you close the container after taking out some grain. I suppose instead of dry ice, a slow feed from a CO2 tank, until the O2 has been replaced, should also work - haven't tried it though. Greetings Llew South Africa Return to table of contents

I'm sure Jeff Renner will chime in here. But just in case, Brown malt goes exceptionally well in a stout. I had some brown malt that I bought on a whim when we first started to get access to imported malts over here. (heartfelt thanks go to Wes Smith) After seeing numerous comments about how astringent it could be I was wondering what to do with it, when I saw a post from Jeff with a stout recipe using a proportion of brown malt. The resulting stout that I brewed was not only enjoyed immensely by myself but did well in both inter-club & state wide competitions so when Jeff re-posts his recipe I say go for it.

It's funny that Mittenwald was mentioned because my brother-in-law was just telling me that I had really missed out by not making that side- trip. But has anyone mentioned Andechs? It is a brewing monastery about 60-90 km west of Munich. I think it's on lake Amersee (and the spelling doesn't look right, but phonet- ically, that's the lake). Definately hit Andechs-- the beer is fabulous and the food is good, hearty, and copious. Not to mention the place is beautiful.

I believe that you may be milling the malt too soon after adding the water. I always weigh the malt into a cooler, sprinkle with water (1T / lb), then leave it overnight to absorb the liquid. The next day the malt isn't even noticeably moist - but it does seem a bit softer, and it mills beautifully. Greg R asks about the variations in the recommended "maximum" amount of brown malt from various homebrewers, and wonders if it's personal taste, or different brown malt varieties. I believe it's both. I'm very sparing with this stuff due to an unfortunate incident using waaay too much - so though I never use more than 5%, 10% may be a more realistic maximum for my tastes given that Brian used 8% of my very own malt and was happy with the results. I've only used Hugh Baird and Fawcett brown malts, which are surprisingly similar. Others may be quite different, who knows?

First and most obviously, the vendor should make good on their poorly stored product. If this is not an option, my second choice would be to feed it to the doves that congregate on the hillside under the cabernet and merlot in my backyard. But if this malt is that special to you, you can either freeze it or put it in a barrel/trash can and purge with co2 to snuff them out. Beetles being a lovely source of exogenous enzymes, they should help in conversion of the malt. But do me a favor, if you live in the Southwest, don't enter "Beetle Beer" in first round nationals. The thought of even potentially having to judge "Beetle Beer" gives me the willies and opens a Pandora's box of unnerving possibilities I'd never allowed myself to consider. Was that pilsner last year "catty" or had Tabby marked the malt? "Mouse Drop Dunkle?" You've given me new reason to judge coordinate the next one rather than judge.

Date: Wed, 29 Oct 2003 11:03:21 -0500 From: "Steven P. Bellner" <sbellner at chartertn.net> Subject: Temp Gradient in Mash Tun I have a pretty standard converted keg mash tun with a domed false bottom with a thermometer installed about 2" above the bottom head weld. The thermometer probe sticks in about 1-1/2 inches. I have calibrated this thermometer against a hand-held thermometer at several temperatures, and both thermometers read exactly the same. Now my problem arises just after dough-in. There appears to be a temperature gradient formed such that my probe reads about 5 deg. F lower than if I stick the hand-held in the mash and move it around. This is a real problem if one wants to be precise in their mash temperatures. This sort of makes sense though. Heat rises, so one would expect the top of the mash to be warmer than the bottom. Here is where it gets confusing. I began to move the hand-held around in the mash in various locations. When it was held near the probe, the temperatures matched. Move it towards the top, and the temp would rise. But when I stuck it in the false bottom, the temp rose as well. It appears as though the temperature gradient from bottom to top goes through a local minimum right where I have my probe installed. I wonder if the heat capacity of the metal is causing the bottom temperature to stay elevated? It would seem the only way around this problem is some form of continuous mash agitation to add some forced convection to the contents. I don't have a HERMS, but it would seem that mash liquor recirculation could also solve the problem. In all of the home brewery designs I have looked at, there didn't appear to be a device used to address this issue. Do others routinely see this problem? Would gentle continuous agitation cause HSA problems? Perhaps it is just a matter of learning the nuances of my system and learning to compensate, but it sure would be more reassuring to me to be able to look at the thermometer and know that is the current mash temp.

Date: Wed, 29 Oct 2003 11:09:20 -0500 From: Jeff Renner <jeffrenner at comcast.net> Subject: Re: brown malt (pt. 1) Andy Bailey <atmlobailey at cox.net> of Las Vegas, NV has started a nice discussion about brown malt and asks for a stout recipe using it. As has been pointed out, brown malt was the original malt used in porters. This was produced differently than modern brown malt in that it was diastatic, but I do think that the modern is the same color as historic. The very fine little book "Old British Beers and How to Make Them" (2003 third edition) by Dr. John Harrison and the Members of The Durden Park Beer Circle has a good discussion of the various historic malts and their use in historic recipes. I recommend this book. I think it now available from some US suppliers. You can also get it from CAMRA or from Durden Park member Geoff Cooper in London if all else fails (contact me for his email). BTW, there is a great story in the beginning of the Durden Park book, regarding how authentic the recipes might be: "The only honest answer is that for the majority of beers described there is no way we can ever know. The exceptions are those beers that remained virtually unchanged up to 1914. [me - WWI brought drastically reduced OGs from which British beers never recovered] In 1973 when we started the programme, there were some people around, aged 79 and older, who were in their twenties in 1914. Such people might remember drinking pre-1914 beer. "We encountered one such person by accident. On Christmas Eve I left a few pints of draught Whitbread's 1850 porter with a brewing friend, Don Hebbs. I heard the rest of the story two weeks later. On Christmas morning he asked his daughter's fiance's grandmother - a spry old lady of 86, if she would like a bottle of Guinness. On getting her approval, he went and fetched a pint of my Whitbread porter. The old lady took a swig and turned a beady eye on Don, she took another long pull, looked him straight in the eye and said, "That's not Guinness, that's London porter! Where on earth did you get that?" Don was totally flabbergasted. he did not know that the old lady knew what porter was, never mind able to recognise it. It transpired that she, as many girls did at the time, entered domestic service when she was fourteen. As was the custom then, she was given so many pints of porter as part of her board. When porter disappeared she switched to Guinness. It took only a third of a pint of porter to set those memories flooding back." My understanding is that the historic brown malt was kilned more slowly so as to preserve the enzymes, but modern maltsters don't bother since the malt isn't used as 100% of the grist. Harrison writes that brown malt (also called porter malt) "was also known as blown malt due to the popping of the malt during production. Modern brown malts are roasted differently and do not pop during production; neither are the diastatic. With the invention of the hydrometer and its application to brewin in the late 18th century, it was discovered that brown malt, while cheaper per unit than pale malt, was actually more expensive to use as it yielded 15% less fermentables. In 1817 D. Wheeler invented the cylindrical drum roaster which allowed the controlled roasting of grains without charring them. Naturally, the product was called "patent" malt. Harrison writes that within five years most London porter brewers switched to pale malts plus a portion of black patent malt. While the new porter looked the same, there was a difference in flavor but this was accepted by consumers. My project for next brew (probably this Monday) is a recipe from the Durden Park book, either an historic porter with a high proportion of brown malt or a strong (1.062) bitter based on an 1880 recipe from the Simonds brewery in Reading. Harrison describes this as a favorite of the beer circle. It uses some home roasted pale amber malt. The book describes how to produce this as well as amber and brown malts. BTW, some of the recipes call for large portions of brown malt, even a few with 100% ( plus brewing enzymes). I say, go for it, Greg. 25% doesn't sound at all too high, but you'll need to give it some age. Jeff - -- Jeff Renner in Ann Arbor, Michigan USA, JeffRenner at comcast.net "One never knows, do one?"

I also remember measures like "coffee cup" (worked out to about 1/2 US cup or about 120ml). So even places that are supposedly metrified still use some "old" measures.

One possible solution is to use Diatomaceous Earth as a pesticide. DE is a fine powder consisting of various shaped (non-homogenous) fossilized organisms with many sharp edges. It works as a filter-aid in brewing because its non-homogeny keeps it from compressing. In pesticide use, it works by coating the insects then grinding through their exoskeletons and drying them out, i.e. they bleed to death. It can be spread in infected areas, and even be mixed directly into your grain. It should be used with care as you don't want to inhale it. You may want to wear a dust mask during application. I'm not sure of a source for DE. A garden store may have it or perhaps a local brewery would be willing to provide you with a small quantity. I'm assuming that the pesticide DE is the same grade and size as filter-aid DE. Doug Hurst Chicago, IL [197.5, 264.8] Apparent Rennerian Return to table of contents
Date: Wed, 29 Oct 2003 13:07:09 -0500 From: Robert Sandefer <melamor at vzavenue.net> Subject: Re: Re: Brown malt Greg asks several questions about brown malt. Here's a somewhat jumbled response: Modern brown malt is a roasted malt similiar to but less roasted than chocolate malt or black patent. As a roasted malt, it lacks enzymes. In the Zymurgy article "Perfect Your Porter" (Vol 19 No 2 Summer 1996) Terry Foster writes that modern brown malt is not the same as the original and recommends using no more than 1.5 lbs per 5-gallon batch. On the other hand, historical brown malt does not (necessarily) lack enzymes and is not highly roasted. There seems to be some discussion about the exact characteristics of brown malt but everyone seems agreed that it was kilned more than pale malt. To my knowledge, there are no modern brown malts that match the original. There are however ways of recreating historical brown malts by roasting pale ale malt in an oven (google search can find directions). IMO any recipe calling for brown malt to make up a quarter or a half of the grist is likely to be a historical recreation requiring the use of the less- roasted, home-made brown malt. Based on all of this, I wouldn't personally use modern brown malt for more than 10-15% of a grist. On the other hand, I would use historical brown malt for half or more of a grist.

It is probably a never ending and unresolvable question regarding exactly what is/are the difference(s) between porter and stout. Historically, stout porter was a strong version of porter. I hope anyone who brews this or tries reproducing historic diastatic brown malt will report back. ======== Geoff Cooper wrote: On Wednesday, October 29, 2003, at 04:03 pm, Jeff Renner wrote: >Andy Bailey <atmlobailey at cox.net> of Las Vegas, NV has started a >nice discussion about brown malt and asks for a stout recipe using >it. > [snip...] >My understanding is that the historic brown malt was kilned more >slowly so as to preserve the enzymes, ... > ... was also known as blown malt due to the popping of the malt >during production. Brown malt was was (historically) roasted over hot fires (often including hardwood 'faggots'). The high temperature caused the popping. John's research appears to show that by roasting for a controlled period at high temperature, the outer part of the grain would roast (producing the colour) but the inside would remain much less cooked - a bit like a rare joint of beef or steak, coloured on the outside and only partially cooked on the inside. This inner core would remain pale and would retain the diastatic activity needed for the conversion. This was clearly a skilled activity - both the amount of heat and the time had to be right to get acceptable brown malt. >On to Andy's request: > >Just curious, anyone experiment with brown malt in Stout? It seems >from the previous responses that it would add some nice complexity >to a stout in addition to the "required" roasted barley. Andy is quite right, small additions of other more lightly roasted malts can provide an improvement to the flavour profile of a stout.

Pritchard" <cdp at chattanooga.net> Subject: re: grain beetles + Counter Pressure Bottle Filler Isaac Gibson has grain beetles in his malt and asked: >Can I mash them? Will that affect my beer? There are some larvae >in some of the bags. I once got a 55# sack of pale ale malt which had maybe 1/2 cup of live weevils in it- didn't notice any larvae. I put the malt into cornie kegs and purged/pressurized with CO2 via the brew-out fitting. That killed all of the buggers. Kept it in the kegs and repressurized with CO2 after opening to retreive malt for brewing just to be safe. All the brews came out fine. If you have many more bugs, you might want to consider screening the malt before brewing with it. - -------- Dan Hansen posted about flat brew when counter pressure filling bottles. If I have the time, I often increase the keg pressure by 5 psig or so several days before bottle filling. Don't try shaking the keg to speed increased carbonation- it will cloud the brew if there is any sediment in the keg. c.d. pritchard cdp at chattanooga.net http://chattanooga.net/~cdp/ Return to table of contents

Kajdasz) Subject: Aquarium pumps and charcoal filters Is it necessary to deodorize the air from an aquarium pump when using it to aerate wort? I have an in-line 0.2 micron filter, but I'm a little concerned about the rubber odor coming out. I'd rather not have to make a charcoal filter if I can avoid it, but if it's for the good of the beer.... Thanks. Steve Kajdasz Lebanon, NH Return to table of contents
Date: Wed, 29 Oct 2003 21:14:07 -0500 From: "Jeff & Ellen" <JeffNGladish at ij.net> Subject: water chemistry experiment On Saturday for Teach a Friend to Homebrew Day, I'm going to brew two five gallon batches of English pale ale with the only controlled difference being the water chemistry. I'll be trying to add to John Palmer's (?) experiment, prepared for the AHA Conference this summer, to see how much the water influences the hop expression. One brew will use distilled water with salts added to mimic Burton-On-Trent water. The question is, should the other brew use distilled water or my normal, soft well water? My opinion is that using my normal brewing water would get better mash efficiency than distilled water and would make the differences between the two beers more likely to be boil/fermentation/hop comparisons rather than efficiency comparisons. But I like the idea of having such a stark contrast in water chemistry by using distilled water to begin with. What do you think? Without doing three brews in the same day, which would make the more telling experiment? Jeff Gladish, Tampa Return to table of contents
