Has any tried this? I've seen the article and recipe in the special issue of Zymurgy on indigenous brews. Is this a good recipe? Any suggestions or techniques would be greatly appreciated.

Date: Tue, 11 Apr 1995 20:41:16 -0400 From: JOHNMAJ at aol.com Subject: Trub, Wort Chillers,Rims Dan Pack said: What I did was stir the cold wort in a circular motion to set up the whirlpool and then let the break settle for 15 min. Well this didn't work for beans. Dan you might want to make a counterflow chiller. You probably have every thing you need. Simply take your 50 feet of tubing, and coil it in a bucket. Put the bucket in your sink, and fill it with water. Go to the drug store, and buy on of those faucet to hand held shower adapters. Cut of the shower head, use this hose to put the water into the bucket at the bottom. If you put the hose in so the outlet is laying along the side of the bucket, the flow will create a whirlpool effect in the bucket. Using this kind of chiller you can whirlpool the hot wort, which I do, and have no trouble in keeping at least 90% of the trub out of my fermenter. Of course you will still have the cold break, but you can't have everything. Also I have never had a beer go bad because of trub in the fermenter, provided I did not leave it on the trub too long.Chris Barnhart said he was making a 3 barrel Rims system, and asks how previous systems were plumbed. First a word of warning. My friend and I used the RIMS system, and were so pleased with it we tried to make a bigger one. We tried to make a 1 barrel system using a 106 quart cooler as our Mash\Lauter tun. We were using a 5500W 240v water heater element with 120v for approximately 1375 watt output. At this power level it took 50 to 70 minutes to go from 122 to 158 degrees. Also at this size of batch the famed temperature variation of plus or minus .1 degree vanished. The mash was so large we could not evenly distribute the heated liquid. We therefore had to heat till we were within 10 degrees of target temp, stop recirculateing, and stir the mash to equalize the temp variations. We would then find out where we were temp wise, and start heating again. If we did not stop periodicly to mix, we could easily take portions of tha mash above 170 degrees. In summary for batch sizes up 25 lbs, and probably a little above that the rims system is great, but for 50 LB mashes or above its marginal at best. As for plumbing we used those steel braided hoses that are in hardware stores for hooking up dishwashers. I know its not food grade plastic inside the braid. We let the RIMS system run for 9 Hours, at 200 degrees with just water in it. Cooled the water drank it side by side with the same water, and could not detect a difference. We have now used these hoses on upwards of twenty batches with no problems. We still use them for reculculating our mash to clarify it, and for delivering our sparge water to the mash tun.

Date: Wed, 12 Apr 95 04:30:49 EST From: ramsey at tccbbs.com Subject: help for a novice I've just made my first batch of brew at Christmas for a gift and it turned out pretty good and without all the trouble that I had anticipated that it might be. (Waiting was the hardest part!) I've been reading this echo for a little while to pick up some pointers and I have a few questions that I hope someone can help me with. 1. I'm looking for some pointers for making a non alcoholic beer. If this is possible. 2. I viewed the competition results and noticed that there is a catagory for herb beer and herb mead. I'm interested in finding out more about both of these. I made my first batch of mead this past summer and was not too thrilled with it. I'm hoping that it will develope some body as it ages. I was more satisfied with the clover mead and it's mellow flavor. I grow herbs and keep bees and would love to combine the two. At this point any help is appreciated whether in e-mail or here in the digest. Thanks Cheryl ramsey at tccbbs.com Return to table of contents

(Pat) Babcock) Subject: CO2Disconnect/Orval/Piddling Schmidling Revisited Greetings! >> In HBD 1702, Matt Wuerstl asks about using garage-type disconnects on his CO2 tank... Bingo! I've been using just that. Brass compressed-air disconnects such as those used by your friendly (if expensive) neighborhood mechanic. In a little better than a year, no problems. With a fresh tank and open flow, I've observed some condensate in the clear tube leading to the disconnect; but it has done little more than feed my idle curiosity. >> In a previous (forgot the number) HBD, Algis Korzonas responds to a (friend of a) potential commercial brewer that he has some homebrewed Orval aging in his cellar... Well, Algis, being of a curious nature, and never having had Orval, I ran out to the store and bought a bottle. The end result is that I will BEG, if necessary, for that recipe. Please-oh-please-oh-please. Private e-mail if afraid that commie (commercial) brewer is listening, but I'd bet there's a whole GROUP of us who began uncontrolled salivation upon mention of this... >> Jack whines online... As a "proud" owner of a Schmidling Maltmill (tm, r, C, and whatever other little letters may be applicable), I can attest to anyone out there that you will find none finer; short of a commercial 6-roller mill. Upon purchase, I will advise you to close one eye, and squint the other before reading any enclosed literature. One of those cheesey, dot-matrix printed pages are 'directions' (pitiful at best, but the only thing you really need to know is to ignore the little man behind the curtain... oops! Wrong movie. Ignore the o-ring around one roller); the rest is advertisements for exactly what you've purchased. I guess you're supposed to give them to your friends... Now, that aside, I do respect JS for his contributions. I don't agree with his whinings. It's not jealousy that goads us on, it's your apparent lack of security. You're like the little kid on the playground that just never quite got big enough, and cries far too easily. Let your products stand on their own quality. Don't bemoan that one potential lost sale. It just cheapens the value of your products and opinions. Oh, well. Now I'm a playground bully, I suppose... Brew On! Patrick (Pat) G.

The Derby Brew Club here does at least one all grainer at every meeting for consumption at the next meeting. I know one month is fast but aquick fermenting Ale yeast and force carbonation in a keg makes for a quick beer. The Rapscallions of Wichita used to do at least an extract beer every meeting as well. The preferred method was to pass a hat for donations for the brew at Wichita... I think in Derby the brewer pays for the batch and the brewing duties rotate. - -- -Lee Bussy | The 4 Basic Foodgroups.... | leeb at southwind.net | Salt, Fat, Beer & Women! | Wichita, Kansas | http://www.southwind.net/~leeb | Return to table of contents

They are indeed the same thing because >of the commutative law of multiplication. This misconception is much more common than I thought. As used in physics and engineering, foot-pounds and pound-feet are *labels* used to differentiate two different quantities. They are not part of an algebra equation. Yes, the commutative property of multiplication applies, but only within the quantity you are measuring. It doesn't matter what order distance and force are multiplied to get work, nor does it matter what order force and moment-arm length are multiplied to get torque. It *does* matter if you try to substitute one for the other, because then you are talking apples and oranges. I recommend any textbook on basic physics for a more detailed explanation. As we have strayed from my original brew-related question, I'm happy to discuss this off-line. For those who still think the two quantities are the same, I offer the following exercise: you are changing a flat tire and apply 200 pound-feet of torque to the lug wrench for 30 seconds. You are exhausted but the lug nut hasn't moved. How much work was done (in foot-pounds)? The answer is zero. Rich Benedict (dick at ccgate.dragonsys.com) Return to table of contents

I can handle that part. My question is, what effect does an activated carbon filter have? I believe it reduces the clorine (which is why I installed it in the first place) but what does it do to the salts, ph etc. And a second question, how about reverse osmosis water?

Date: Wed, 12 Apr 1995 09:34:23 -0400 From: Robert Rybczynski <robert at umbc.edu> Subject: Beer spiced with dry chiles About 2 months ago I asked a few questions regarding the use of dry chiles in beer. I received some interesting and helpful suggestions. In the end I did my best to combine this collective wisdom, but my first attempt is no stunning success. Neither is it a failure. It's slightly warming with no chile aroma. Here's the recipe for 5 gallons: 5 lbs M&F light dry malt extract (unhopped) 1 oz Cascade pelletized hops (6.2% AA) 6 Chinese (Szechwan?) chiles 1 pkg Yeast Lab Whitbread Ale Yeast 3/4 c. corn sugar for priming 8 chiles used for dry spicing (6 steamed, 2 unsteamed) Removed stems and seed from chiles. Boiled extract and hops in ~3 gallons of water for 1 hour. Steeped chiles from 10 minutes, then discarded them. Started yeast in a small yeast starter. Pitched when wort cooled (I don't have a wort chiller). Bottled approx. 10 days later with priming sugar. Before bottling I used a wine thief to taste the beer. Since the heat from the chile was low I decided to steam a few chiles and "dry spice" in the bottle. I also made two bottles with unsteamed chiles. I'm not going to throw the chiles in the brew pot again. Very little spice was contributed from the six chiles I steeped. I'll not put one chile in each bottle again, either. Fortunately, I limited this to 8 beers. The steamed chiles made the brew overpowering. The unsteamed chiles were worse, with a mild infection that caused those beers to become hazy. The problem is not the heat. The dry spiced bottles are about as hot as Pace hot salsa. It's the chile aroma that makes the beer undrinkable. My next attempt will utilize dry spicing in the fermenter. I'll try 6 to 8 steamed chiles in a musslin bag. Also, I'll put more hops in the boil (1.5 oz of similar bittering hops). The chiles seem to provide heat and aroma, which leaves flavor wide open to bittering. Return to table of contents

My sanitary engineer spilled some of my spent mash from my garbage can at my curbside. I now have a virtual barley forest at my mailbox. The only problem is that it was from a multi-malt brew and who can tell which one(s) it is that survived? In the future it might pay to brew a single barley and methodically plant the spent mash. Sounds good in theory but something tells me that the only sure way it will grow is when you don't want it to....don't know which one it is....or don't like the type it is!!!! Regards, Todd A.

Date: Wed, 12 Apr 1995 9:56:42 -0400 (EDT) From: spencert at justice.usdoj.gov Subject: Partial Mash Qtn, Liquid Yeast Advice Greetings Brewthren: As an extract brewer only (so far), I want to try two things to improve my brew: partial mashing and using liquid yeast. I recall reading in a back issue of the HBD, perhaps from a year or two ago (of course I didn't save it), someone writing about a first timer's partial mash system consisting of using an EasyMasher and flexible tubing to siphon the mash out of a kettle. I would like to try this, and would appreciate hearing from those with experience using this setup. Suggestions and advice are most welcome. Also, I am convinced by many HBD writers that liquid yeast is the way to go. I would like to hear from those who have switched from dry to liquid, specifically how the switch affected the taste of your brew. I have read the yeast faq, but I'd appreciate hearing first hand experience. Many thanks, many of you have already helped me with the great info I've picked up in the HBD. Private e-mail fine, I'll post results if warranted. Tim Spencer spencert at justice.usdoj.gov? Return to table of contents

Their value is greatly diminished, though, when the number of entries per category, or the actual scores, is not included. I'd also like to see results of the various wide area or national contests published. Why does there never seem to be any information posted regarding the 6 AHA Club-Only competitions?

Date: Wed, 12 Apr 1995 11:19:33 -0300 (ADT) From: Ed Hitchcock <ehitchcock at sparc.uccb.ns.ca> Subject: You say Bernouli, I say Venturi... Just a little more confusion for the whole venturi/bernouli discussion. For starters, I like the conclusion that a _venturi device_ operates on the _bernouli effect_. Sounds good to me. However, I would just like to point out that the holes-in-racking-tube aeration device has nothing to do with venturi or bernouli principles. The venturi suction device you mount on the tap (a wonderful investment for homebrewers, by the way) operates by constricting the flow of water under pressure to rapidly increase the speed of flow, and this jet is sent through a chamber which is open to the air, or suction tube or whatever. The racking cane aerator device uses no restriction, and the flow of wort is not under pressure. It is the weight of wort below the holes which generates the negative pressure and sucks air in through the holes. If one were to force a liquid through the tube under pressure it would squirt out the holes, not suck air in. Thus the holes-in-racking-tube aeration device is not a bernouli, is not a venturi, but is a *hydrostatic* aeration device.

Date: Wed, 12 Apr 95 10:19:02 edt From: Robert_Ser at ceo.sts-systems.ca Subject: BIG Pot... CEO document contents: Brewing buddies, During my searches for a second hand boiling pot, I have come across a beautiful high quality, heavy gauge 316 stainless steel kettle sitting in a corner of my parent's garage. It has two welded handles, but no cover. The only problem is its size... This little baby measures 21" wide and 30" high. A quick calculation will show that it can hold almost 44 gallons (166 liters). I think my wort chiller would just get lost in there. So, before I do something drastic like cut it in half or try to swap it for something smaller at a local shop, I thought I'd give larger-scale homebrewers a chance at it. I am not trying to sell it or make a dollar off it, but I would be happy to trade it for another high quality stainless steel pot in the 10 gallon range. If you are interested, please feel free to contact me. Private email is probably best... Robert Servranckx Robert_Ser at ceo.sts-systems.ca Montreal Return to table of contents

Date: Wed, 12 Apr 95 10:43:55 EDT From: spencer at med.umich.edu Subject: Tubing warning I recently replaced all my plastic because of a possible low-level infection problem. The new tubing I got from a local homebrew shop had a "plastic" smell to it. I didn't think about it, figuring it'd "wash out." Well...... Last night I had to dump 10 gallons of otherwise very nice "plastic" beer down the drain. I use a counterflow chiller, and the wort had apparently picked up the plastic flavor/smell from the hot-side tubing. Needless to say, I'm trashing that tubing, and have bought new tubing that doesn't smell. I will also test the new tubing with boiling water before using it. :-( Does anyone have a source for small quantities of Tygon tubing? =Spencer Thomas in Ann Arbor, MI Return to table of contents
Date: Wed, 12 Apr 95 11:02:41 EDT From: spencer at med.umich.edu Subject: Re: Brewing waters of the world (longish) As I understand it: Ca++ & CO3--/HCO3- affect the mash, Ca++ by helping release phytic acid and thus lowering the pH, and CO3--/HCO3- by raising the pH. Mg++ is an important yeast nutrient in small amounts. SO4-- "enhances" hop bitterness, giving a dry bitterness characteristic of "Burton" pale ales. HCO3-/CO3-- interact with hop bitterness to give a harsh flavor. Cl- (and/or Na+?) helps "smooth" the flavor in small amounts (essentially like small amounts of salt round out the flavor of food). Thus, it's important to do Ca and/or CO3 additions in the mash, if you're trying to adjust/buffer the mash pH. The others can be added in or after the boil. I don't think (but could be wrong) that any of the ions significantly affect the boil. Please correct me if I've misunderstood something (not that most HBDers need an invitation :-). =Spencer Thomas in Ann Arbor, MI Return to table of contents

Muzidal) Subject: Antibacterial dish soap The stores in my area (Dallas) are now selling Antibacterial dish soap. Actually, it is labeled as "Dish Soap and Antibacterial Hand Soap". Does anyone know if this stuff is OK to use on brewing equipment, and if so, would it eliminate the need for an extra sanitizing step (with Idophor, etc...)? The active ingredient is labeled as "Triclosan", which I would guess is the antibacterial agent. This would make the brewing process much easier, but I am affraid that it is not strong enough for brewing purposes. Anyone have any thoughts on this?

Date: Wed, 12 Apr 1995 11:28:10 -0400 (EDT) From: Eugene Sonn <eugene at sccs.swarthmore.edu> Subject: How to tell when a keg is carbonated? Here's a question for the collective wisdom of the HBD: I'm making a triple batch of an oatmeal stout and "bottling" it inside a 15.5 gal sankey keg. I've done this once before with great results (a strawberry wheat), but this time I have to do it on a tighter schedule than before and am wondering if there is a way of checking on the progress inside the keg. Unlike bottles which you can look throught to see how much yeast is in suspension, the keg is rather hard to see through. I also have the added difficulty of not having access to a CO2 drive for the keg. Any suggestions? Thanks in advance, Eugene Return to table of contents
Date: Wed, 12 Apr 95 10:36:24 CDT From: Timothy L. Burger <burger at calshp.cals.wisc.edu> Subject: Altered Beast Full-Name: Timothy L. Burger Thanks to all who responded to my question regarding the viability of the starter I concocted. The majority of responses suggested that the activity level of my starter was normal and that my expectations of wild frothing were unrealistic. Basically I had no airlock activity and a meager head in the bottle but after three days had accumulated a healthy layer of gunk on the bottom. I was advised by most to take a whiff and unless I detected a foul scent to pitch it to the wort which I did and a vigorous ferment ensued. I racked to a secondary and plan on letting it sit until after the weekend before bottling. My main concern was the lag time between adding the yeast to the starter to the time I saw any action. I thought that some other beasties could have taken over in the time it took the good guys to kick in. The date on the yeast culture was May 5, so that could have contributed to the delay. Anyhoo, thanks again, you saved this greenhorn five bucks. I'll drink to that. Tim Return to table of contents

Any > opinions out there? Okay, there are generally two types of buckwheat I have seen at health food stores. Toasted and untoasted. I can't comment on the untoasted, except that it's a lot cheaper some places, and lighter in color. I've brewed a couple beers with the toasted and am planning to brew a small batch very soon to really "showcase" the toasted buckwheat, to isolate some of it's contribution. (Just pale malt and buckwheat and light hopping.) Brew with it like you would any unmalted grain. It does not need to be malted, but doesn't have it's own enzymes, so it must be mashed. In quantities as low as 1/2 pound to 5 gallons, it adds noticably to the flavor of the beer. It might be a good idea to boil it for awhile to ensure that the starch is gelatinized. (I'm going to try it without boiling, to see.) Crask it open with a maltmill or rolling pin if you can. Buckwheat didn't seem to contribute much to the color of my beer, but both the beers I made with it had other things to darken it. It added a flavor which was similar to wheat, and it added a nice toasted flavor which was slightly different than with toasted (biscuit,victory) malt. It also added a flavor which I can only describe as "hearty", much like what it adds to "hearty buckwheat pancakes". (They always say "hearty" on menus...) So, go ahead and use it. I don't think the toasted stuff would be appropriate for a Wit beer, but I support pioneering a new style now and then. (I myself have been toying with the idea of making a Buck-Wit.) As for the steel-cut oats, I recommend using rolled oats instead, but I'm far from an oaxpert on the topic. -R Return to table of contents

I had a brew down in which I had used laaglander dry malt. The fermentation process froze at 1.024 or so. I talked to one of my local homebrew stores and the guy recommended using the enzyme, which would break down the complex sugars in the laaglander into simple sugars the yeast could eat. I guess laaglander has a higher complex sugar level. I used about a teaspoon to 5 gallons. Fermentation restarted not long after. Final reading was 1.008 or so. I'm not really sure if the taste was affected or not, though the brew did stay rather sweet tasting. I don't know if adding the enzyme to the boil would be a good idea...any chemists out there know what happens to enzymes in high heat? I'm not even sure you'd need to use it unless you are having severe problems with complex sugars...I suspect that the heavier types of brew may be worrisome. Keep in mind that I'm an extract brewer, too, so maybe my commentary is not applicable...never stopped me before, though. :) Collin Ames c-ames at maroon.tc.umn.edu Collin Ames Office Specialist Office of the Registrar - Registration Center 202 Fraser Hall Return to table of contents
Date: Wed, 12 Apr 1995 12:14:32 -0500 From: keithfrank at dow.com (Keith Frank) Subject: Grassy flavor summary A few weeks ago I requested help on a clone of Redhook ESB which was dry hopped with 1 oz. of Tettnanger and had a grassy flavor. Spencer Thomas and Domenick Venezia summarized some past notes in HBD which I've edited and attached below (thanks!). Since my post I met a brewer who told me grassy flavors can also come from improper conditioning, i.e. not enough time in the fermenter. I also heard from a brewer in Houston who used the same recipe I did and also got a grassy flavor. For this beer my conclusion is the grassy flavor was due to dry hopping with Tettnanger. My beer tasted great out of the primary and grassy out of the secondary. The hops smelled fine (no cheesy or off aromas) and have been used in an Alt beer for bittering with no ill effects. Next time I try this recipe I'll either add 1/4 oz. Tettnanger for dry hop, or use Domenick's procedure at the end of this post. The flavor is fading very slowly with time, so hopefully in a month or so I won't notice. Bruce DeBolt Lake Jackson, TX - ---------------------------------------------- From: SMTP%"Spencer.W.Thomas at med.umich.edu" Some notes from past digests: Al K in 1357: The grassyness could be from stale grain, certain types of bacterial infections (which could also make the brew cloudy) or from stale hops. The cloudy sparge implies that perhaps you sparged too hot -- too hot a sparge (too much over 170F) will liberate unconverted starch from the grain. If indeed the cloudy sparge was from too hot a sparge water, then the beer too has a starch haze. Josh Grosse in 1357: I recall from a recent judging study session that this is mowed- lawn flavor is one of the Higher Molecular Alcohols (HMAs). Yeah, it could be one of the many weird hop produced compounds. Excessive or incorrect HMAs are typically caused by too high a fermentation temperature. Yes, ales have HMAs in them normally, because they combine with fatty acids to produce esters. But too high a temp will cause this sort of thing. Jim Busch in 1364: The aroma profile of EKGs are often described as "earthy" or sometimes "grassy". Its the way the hop is. .. BTW, the initial harshness of some cask hopping seems to blend and diminish over time (if you can wait!). Tim Lawson in 1366: A much more plausible explanation for the grassy flavor can be found in Zymurgy (vol. 10, number 4, 1987). George Fix states that "barley is a member of the grass family, and thus it is not surprising that grassy flavor tones can arise from grains....musty smells will be detected in the malt....the best practical measure for avoiding grassy flavors involves the proper storage of malt....high temperatures and humid conditions should be avoided....malt that has been ground will do this very quickly (i.e., absorb moisture)". Domenick Venezia in 1446: After having a batch develop an unidentified flavor (grassy, grainy, dusty, musty, !?) after some rather aggressive dry hopping I have been trying some alternatives. The last and most successful attempt was a 5 minute boil of 1.5oz E. Kent Goldings followed by removing from the heat, putting on the lid, sealing very well with foil and letting the hops steep for 30 minutes before starting to cool. Just racked the stuff to the secondary Monday and so got a chance to sample it. Yum, yum. The hop aroma was wonderful, rich, full, floral but somehow different from a dryhop aroma, and the hop flavor was very good too. >From a table of hop characteristics posted by Rich Webb: Willamette - American Quality aroma, mildly fragrant, grassy, 4.4-7 good Mild Ales, Pale Ales, Porters, Stouts Fuggles - British Traditional aroma hop, spicy, mild, grassy 2.7-6 good Mild Ales, Pale Ales, Porters, Stouts - ---------------------------------------------------------------- From: Domenick Venezia, venezia at zgi.com I made a grassy brew using East Kent Goldings some time ago. 1 oz for 4 days. I posted a similar question to the HBD and got 4 answers ( These are summarized in detail above - Bruce): 4. Stale malt. George Fix says in a Zymurgy that stale malt can give this flavor note. Crushing the grain and letting sit around can stale it in a matter of days if it is not sealed properly. I finally came to the conclusion that G.Fix has it right - at least in my situation. I used Crisp Maris Otter from Liberty Malt in Seattle. They store their malt in unsealed cardboard shipping barrels and the barrel was almost empty when I bought the grain. They also used to use an expresso coffe grinder to crush (read shred) their grain. ...then I let it sit around unsealed for about a week. I think that there was some interaction between the dry-hopping and the stale grain to create a grassy-mustiness. This NEVER faded with time despite Mark Garetz's statement.

Greetings HBDers, I just finished brewing a Coffee Porter and was wondering if the resulting beer will be caffeinated. It is a 21 litre (5.5 gallon) batch with 230 grams (1/2 lb.) of coffee (yes, I love coffee almost as much as beer). I added the coffee grounds at knockout. So if anyone has any thoughts on the possibility of my homebrew being caffeinated or if the caffeine is somehow scrubbed out in the process of fermentation, it will be greatly appreciated. - -- "Come my lad, and drink some beer!"

Apparently this gives the beer a >"ham" taste. I will definitely not try that. Ham? In beer? Yeeech. I'm not sure if Valencia oranges would cause this flavor, But I have heard that Wyeast Wit yeast strain can give an off flavor of meat or salami. Perhaps this is the source of the "ham".

Sapsis" <dbsapsis at nature.Berkeley.EDU> Subject: mashing dark grains/sprouting spents OK, I'll bite: Paul Baker queries the Digest's wisdom in regard to handleing the extraction of dark grains. He mentions that this thread had previously been sorted out to the conclusion that said grains should only be added at the end of the mash. As a previous contributor (gadfly?) to this thread, I wondered how he got that impression. Last fall I posted that I was unaware of any commercial brewery that used such a proceedure, while being quite certain of many that add all dark grains to the main mash and proceed as usual through whatever mashing program they use. I asked if anyoner knew of any brewery that avoided mashing dark grain, and recieved no answers. Now, the rumour that mashing dark grains causes harshness and astringency has been around a while, but i have never experienced it where it could not be attributed to some other factor, and have a multitude of experience to reject that hypothesis (ever had a Guinness?). The full mashing of dark grains in regions with highly alkaline water (high carbonate levels) has been an integral part of the development of specific styles of beers; that is, full mashing of dark grains, in contrast to causing astringency, likely reduces it due to proper pH adjustment of the mash. I ask again: Is any commercial enterprise adding dark grains after mashout, and if so, what are the (percieved) results? *********** Bob Jones wants us to believe that spent grain are a viable source for barley propagules. Sorry to dissapoint, but in addition to the fact that malt has already been germinated then stopped by kilning, it has been well established in the fire effects literature that plant tissues are killed by 10 minute exposures to temperatures of 150F, and 1 minute exposures of 160F (these are internal cell temps). Trust me folks, them spents is dead. Now the fact that barley is sprouting adjacent to a spent grain pile does not surprise me one bit -- I have just that happening next to mine at this very moment. the answer lies in the fact that numerous species of the genus Hordeum are common weedy annuals throughout North America. Two of the most common species in the west are _H. leporinum_ and _H. jubatum_.

And, from the private E-Mail, I'm glad to see that I'm not a loner! Basically, the replies suggested that I use a kitchen/bath cleaner that promises to remove hard water stains, such as the Lime-A-Way that I had originally proposed using. One kind person suggested that an acid wash was the only way to remove the deposits. That started me thinking. What is the most benign acid to be found in the kitchen? Right, vinegar. So, last night I washed the interior of my carboy with a quart of plain white vinegar. I used my carboy brush, then rinsed well. I'm happy to say that the residue is no longer there. I would also like to say, that had this technique not been successful, I would have definitely proceeded to the more caustic chemicals. A carboy is a terrible thing to waste! Fr. Bradley A.M.

I basically followed Papazian's Toad Spit Stout recipe from TNCJOHB with several modifications. I used 6.6 lb light, unhopped LME; 3/4 oz crystal, 1/3 oz roasted barley, 1/3 oz black malt; 1 oz Northern Brewer 6.6% aa, 1/4 oz Cascades both for 60 min, no finishing hops. I didn't have any gypsum so I improvised and added four Tums E-X tablets to the boil, each tablet contains 750 mg CaCO3. I cooled the wort, transferred to carboy filled to 5 gal and pitched with about 750 mL starter of Irish ale yeast. (O.G. 1.058) My questions are: 1) Any idea how adding Tums to the boil will affect the flavor? 2) Is 1200 mg Ca about right for a 5 gal batch of stout? 3) Will the CO3 adversely affect my stout? 4) Will using Cascades hops for bittering make this brew not to style with respect to stouts? 5) Should I dry hop since I didn't have any finishing hops at the time of the boil? If so, what kind. Fuggles? Willamette? 6) I think I crushed the specialty grains too much and got too much powder; should I try to filter it out or should I not worry about it? Any further advice as to how I can make a better stout is welcomed! Also, I'm planning on making a wort chiller from copper tubing. I know this info has been posted on the digest. Can anyone tell me which #'s? TIA for any replies.
