I don't think we have to worry about malting- and mashing-resistant barley. Barley should worry about us going extinct. People grow the vast majority of the barley in the world, and without us to propagate it there wouldn't be nearly so much of it. (Although if they find some other way of reproducing, watch out!) Now, what you have to worry about are super-pests who laugh at both insecticides and organic farming methods. Given some bad luck and enough time, a nasty fungus from Malaysia could wipe out the world'scommercial hops fields, or some beetle from Paraguay could wipe out the world's barley crops. As I recall, phylloxera nearly wiped out the European wine industry in the 19th century. I've also read about some problems with hops.

The short answer is "no". There would have to be some sort of advantage for brewing grains to become "mash resistant", and clearly there isn't - in fact, we "speed up" evolution the other way by selecting strains with brewing friendly traits. Hope that lets you sleep better at night.

Blow off tubes are nice for the first day or two as insurance. I don't think the O2 will cause a problem at this point in the fermentation. It may end up quite dry since the Sasion is noted for extremely good attenuation. 1.008 would not surprise me. I would also expect some tart dry qualities from the yeast. Out of style for a dubbel, but a nice beer none the less... I occasionally have to use a non-style yeast to recover a batch, or to brew because I have the wrong yeast ready. I used a Straffe Hendrek yeast slurry I had cultured once in a Grand Cru because after 5 days my 3787 was not ready and I wanted to brew. Turned out a nice Grand Cru. The Lager I made for Big Brew still wasn't fermenting this morning (12 gallons), so I pitched it with three 11gr packs of Nottingham that were activated in a bit over a pint of cool water, and set the refrigerator to 55F.

I've made a Jalapeno pepper beer and it >tastes damn good. But is it beer ? Mom always told you not to play with your food. Why didn't you listen, Michael ? I think that hot pepper beers are created by folks with an erroneous idea about food flavor. A great beer and a bowl of spicy chili verde go together magnificently exactly because of the contrasting flavors and sensory impressions the two give. Mixing the two together is colossal mistake. Putting chilis or jalpenos into beer is to me about as sensible as running a grilled steak, a baked potato w/ sour cream and a glass of cabernet together in a blender and calling it dinner. It's an offensively bad idea. >I'm not sure about sweet potato... but there might be >room for a pumpkin and some all spice this october! I'm not completely against pumpkin beer as long as you leave out the pumpkin, bump up the gravity, change the spices and call it Xmas ale. The good thing about these vegetable starch beers is that the vegetable flavor is usually too small to appear in the final beer. Seriously - does anyone think that a beer that really tasted like unspiced cooked pumpkin or sweet potatoes or potatoes or zucchini would be a good thing ? Yak ! It's just my opinion.

Baling twine works quite nicely, but get the natural fiber stuff, not the plastic. The nat.fiber stuff is biodegradable and burnable.

Just tie-wrap the twine over the existing wires this year. - -- Now my question: Any good ideas for a hop trellis ? Last year I got advice from an highly inventive brewer who will remain nameless. He suggested connecting10 ft sections of electrical conduit(relatively cheap) to make 20ft poles, then bolting three pole ends together to make a trigonal section about 17 or 18 ft tall. This worked well except the weight and wind resistance of the fully grown hops and the relative weakness of the conduits caused bending and blow-overs. I'm looking at planting 20ft treated wood poles and stringing fencing wire between. Any thoughts ? (I gotta get moving on this one - the bines are already 3-4ft long). -S Return to table of contents

Thus if the total (calcium and magnesium) hardness of the water is 200 ppm as CaCO3 that is 200/50 = 4 mEq/L and the output water will have 4 mEq/L sodium (92 mg/L) in addition to any sodium that was in the water to start with. Such a high level of sodium may or may not be a problem. Loss of calcium definitely is (though I and others, I'm sure, have brewed with water processed through these devices). A.J.

Your fears are unfounded. High quality brewing barley exploits humans to clear fields of competing plants, improve soils, carefully store and plant seed by the hundred thousands of acres. Low quality barley is relegated to unimproved land with lots of competition including human agricultural encroachment. If barley made better bread and tasted great under Szechwan chicken it would probably become the dominant organism on the planet ! Actually it's barley that should be scared silly by evolution.

Date: Wed, 07 May 2003 11:47:43 -0400 From: Alan Meeker <ameeker at mail.jhmi.edu> Subject: honesuckle use Mike in Columbia asks about using honeysuckle blossoms in beer. Mike, all I can say is - good luck. I tried making a honeysuckle mead (a mead subspecies technically called a "rhodomel" I think) awhile back that was spectacularly unsuccessful. I started out with a few pilot experiments first to see how best to extract the wonderful aroma of the blossoms. First, I learned a little something about honeysuckle blossoms I didn't know before. I always assumed that the flowers came in two colors - white and yellow/orange, but upon close inspection it appears that they all start out white and then take on color as they age. Also, I noticed that it is the colored blossoms that are the most fragrant, so I concentrated on these when harvesting. Extracting the blossoms with alcohol or water at various temperatures and for varying lengths of time (basically making teas) led me to conclude that a brief warm water extraction was the best way to extract without appreciably changing the character. Armed with this knowledge I harvested huge volumes of honeysuckle blossoms, made some concentrated tea from them, and added this to the mead in secondary after it was fairly well finished fermenting. My reasoning was that the alcohol was probably high enough to inhibit any contaminants (since this wasn't sterile by any means) and that the CO2 generation was low enough at this point that the delicate aromas wouldn't get scrubbed out. On top of this I "dry-honeysuckled" the batch as well with a large amount of freshly-picked blossoms. I did this in the secondary as well as the tertiary, and I used a LOT of blossoms. The mead cleared nicely and adopted some of the coloration of the blossoms. There was no evidence of contamination, so I had high hopes for this mead. Bottom line however, was that, while it was a good mead, there was virtually no honeysuckle character whatsoever - neither in the aroma nor in the taste. Quite disappointing! This mead was pretty delicate, flavor-wise, so I think that even a mild honeysuckle presence would have made itself known. Therefore, my feeling is that trying to get any honeysuckle character into a beer will not succeed. If you do give it a try though, please let us know the results... -Alan Meeker Lazy Eight Attobrewery Baltimore, MD "Where the possibilities are infinite" Return to table of contents
Date: Wed, 7 May 2003 09:05:28 -0700 From: "John Palmer" <jjpalmer at altrionet.com> Subject: Liberty Hops / stale extract/cidery flavors Joe asks for opinions on Liberty Hops. Liberty is my favorite alongside EKG. I first sampled this hop in Pete's Wicked Lager (which I haven't seen in years), but ever since it has embodied the perfect hop aroma and flavor for me. Just last month I made an all-extract Wheat Koelsch using Liberty exclusively and it turned out great. Here is the recipe: Wheat Koelsch 6 Gallons at 1.050 6 lbs of Wheat Malt Extract (liquid) 2 lbs of Pale dry malt extract Liberty Hops: 1.5 oz FWH (basically I heated the water to like 120F, dissolved the extract in, added the hops, and waited for it to come to a boil. Took about 15 minutes) 1 oz at Knockout when I inserted my immersion chiller. (10 minutes and then began actively chillling) Whitelabs Koelsch yeast The beer came out great, no off-flavors, solid 30 IBUs of bitterness in the finish, with great hop aroma and flavor up front. The wheat malt character is a real asset because it provides for a light body with a firm malty flavor to hang the hops on. *** I have been interested in understanding the most likely source of cidery flavors in extract beers lately. For years I have always echoed the common knowledge that cidery flavors come from adding a lot of refined sugar to canned kits. But in response to a couple threads on r.c.b, I am taking another look at that. For example, Dan Listermann reported that he had made a beer containing a high proportion of refined sugar that had no cidery flavors, and of course there are all the Belgian Tripels out there that are not cidery. The new proposed cause is stale liquid malt extract. My very first homebrew batch was a light beer extract kit from my local brewshop (Fun Fermentations, OOB in the mid-90s). That beer turned out very cidery, and I think the cause was a) repackaged bulk extract, and b) included corn syrup to lighten the body. This most recent beer used bulk extract that was fresh, plus a bag of Briess Wheat Malt extract which I had bought for use as a prop on my book cover, and had stored in the freezer ever since. I am sure it has thawed a couple times in the past 3 years, but apparently it never went stale. The theory now is that the stale extract causes the cidery flavors, and the use of any refined sugar fails to hide those flavors. Any Comments?

I go to the Baraboo Wisconsin region relatively frequently and have been considering the use of the Quartzite for some time.

I am not an evolutionary biologist, nor do I play one on TV. However, I am married someone in a closely-related field. The following is my educated opinion, and I do not intend to start an evolution debate. I merely hope to quell Pat's fears. I doubt we will ever see a malt-resistant grain. As I understand it, malting is the process of allowing the seed to grow just enough to begin sprouting. Brewers like this because the unusable protein/carbohydrate starch reserve (endosperm) breaks down into something usefull to us (and the plant). After conversion, the seed is killed with heat. If there were some genetic modification that made the plant resistant to the malting process, the mutation would also affect the plant's ability to grow from seed. The modified plants would be out-competed by non-malt-resistant plants thereby loosing access to nutirents, sunlight, etc. Mash-resistant strains of grain face the same obstacle, evolution-wise, because mashing is another natural process that humans learned about and adapted the process to suit their wants. I can not say that the possibility is impossible, but resistant grains would mean a change in the fundamental way the plant begins its growth. For those of you that believe in creationism or intelligent design, I offer the following reasoning. Since God is perfect, God must drink beer. Therefore, God would not alter the ancient and time-honored process of producing beer. Unless, perhaps, the process creates better beer. - --Dean - Unscrambler of eggs - -- Quality Web Hosting http://www.3llamas.com Take your time, take your chances [5899.2, 94.2] Apparent Rennerian - ---------------------------------------- It matters not how strait the gate How charged with punishment the scroll I am the master of my fate I am the captain of my soul. - -- Invictus -- - -- William E Henley -- Return to table of contents

For those of you who are very educated I want to first thank you for sharing your knowledge with the rest of us who are only high school graduates or still in collage like myself. That being said given the depth with which you have studied science is it not amazing the complexity an the organization of these things? Is it not also true that they are so complex in fact that even at the highest levels of study there becomes no more knowledge only debates between expert's? If we as humans can not fully explain the complexity of our world in even the smallest detail: take for example light is it a particle or a wave? If we can not explain these things is it logical to assume we know how they came to be here in the first place? It is true man has learned much about this his world so much in fact that you could spend a life time of study in just one field, but at the end of your life would you know it all about that subject? NO, however you would have much to pass on to the next generation. Can you then propose how it came into exist in the first place? For those that do, I have a question for you: we as a human race are evolving right? But then we keep our sick alive and attempt to prolong the life of the aged? Are we going to evolve or digress as a species? Since nature selects only the fittest to survive are we not disrupting the natural progression of life by attempting to treat people with medicine? Now many diseases are cured and I'm not suggesting we allow people to die, however by keeping them alive and if they have children we eliminate natural selection? Is that not correct? Theory's are wonderful but let us accept then for what they are THEORIES. There is a great rift between the science world as to creation or evolution. There are compelling arguments for each side, please investigate both before you make a decision. Remember it was not to long age we bleed people to let the bad spirits out so they would get well!! Today's geniuses's in 500 years will be considered children in there understanding because ec 8:17 says " And I saw all the work of the [true] God, how mankind are not able to find out the work that has been done under the sun; however much mankind keep working hard to seek, yet they do not find out.

For the rest of the Group, relax. You're barley will not turn poisonous or grow tentacles. It is true that various molds and microorganisms secrete various chemicals to limit competition (e.g.,other molds and microorganisms on the melon). In the vocabulary of my field, the secreting organism(s) is biologically exploiting the other organisms. This means the presence of the secreting organism deters the growth of others species. This however is not applicable to barley (or hops or yeast). Why? Because human beings do not biologically exploit these species. Our presence in an area does not cause the populations of these species to decrease. Indeed, we are mutualists with these species. Human presence tends to increase the populations of these species in an area. Think of it this way: Before the cultivation of barley, how much land did barley grow on? How did it spread into new areas? How many continents did it grow on? After humans started growing it for flour and beer (yeah), how would these answers change? As far as I know, barley is now grown on 6 continents, its protected by wonderful helpers called farmers, and has a lot bigger population size than it did in the wild (speculation true but it makes sense). All we ask is some assistance in making beer, but as a species, barley comes out well. Therefore, to my knowledge, there isn't a creditable biological theory that would support the occurrences feared. I now return you to your regularly scheduled beer.

No way! As has been pointed out here before, we THINK we are exploiting barley for our purposes, but in fact, barley is exploiting us for its. Think about it, without barley's wonderful beer making qualities, what would it be? Just another feed grain, and not nearly as successful, at least by the standard of how much is growing in the world at any one time. Barley's success depends on its ability to exploit humans.

Comments and >details from the experts in here would be greatly welcome. ****************************************************************************** *** Brian, I'm the culprit responsible for the Zymurgy article you quoted, and would be glad to add a few extra comments. The Schmitz process is briefly mentioned in volume 1 of De Clerck's "A Textbook of Brewing". Assuming you wish to decoct, it can save you time and effort (and mess) if you have the ability to boil the mash directly in the mash/lauter tun. The convenience lies in not having to pull the decoctions, then remix them in an attempt to hit your desired rest temperatures. Simply apply the heat to reach your temperatures, then draw off some of the wort before boiling the entire mash. Any starches released during the boil can then be broken down by the enzymes remaining in the wort that you drew off earlier. You just need to cool the mash down somewhat before reintroducing the wort. I must confess that have never used this technique to produce a Pilsner, but it makes for great bocks, dunkels, and O-fests. I haven't run any side by side experiments to directly compare it with other types of decoction mashes. One thing to consider is that even with a triple decoction mash, about 30 % of your grist will never be treated to a boil (assuming that you pull one-third of the mash to decoct and remix evenly). About 44% will be boiled one time, 22% will be boiled twice, and about 4% of the grist makes all 3 trips to the boiler. Double decoctions leave about 44% of the grist unboiled, with 44% boiled once, and 11% boiled twice. The Schmitz process ensures that all of the grist is treated to a full boil. As a side note, I recall a conversation that I had with Mark Naski of the St. Louis Brews a few years ago. He stated that on a brewery tour in northern Germany, the tour guide described how they boiled their entire mash just prior to lautering. The name of the brewery escapes me, but I believe they were producing a Pils wort at the time. Perhaps others might have more info on the commercial use of this mashing technique. Hope that makes it a bit more interesting and a bit less scary. Prost ! Wm. Shawn Scott McAlester, OK wscott at lakewebs.net Return to table of contents
