Pyle <npyle at hp7013.ecae.StorTek.COM> Subject: 215 IBU / Zapap Hop Back The Rev. Ed Blonski writes: >The Hop IBUs is 215.2. And I'm not sure exactly what that means. Here's what >I got for hops: > 4 oz. Brewers Gold (pellets) 8.8% 75 minute boil > 1 oz. Eroica (pellets) 9.5% 45 minute boil > 3 oz. Cascade (plugs) 5.2% 15 minute boil I'll tell you what it means, Ed. It means heaven on earth! Halleleuia! Oops, sorry to get back on that religion thread, but I can't help myself... Yaaaaaaaaahoooooooooo! Party at Ed's house in 3 weeks! OK, this beer used 15 lbs of syrup in, presumably, 5 gallons of wort, which comes out to a big beer (over 1.100 OG). This means your hop utilization will be reduced substantially, and I don't know if there's real good data as to what happens at such high gravities. For example, I brewed a barley wine-lite at OG 1.085 and calculated IBUs of 60. In theory, this beer should be pretty balanced, but it comes off quite sweet and not at all hoppy to me. I suspect those IBUs are really much lower. OTOH, this beer should have plenty of hops to handle all that malt, probably too much. If it's too bitter for you Ed, I think I know someone who'll take it off your hands for you, for free!!! ;^) If nothing else you can mix it with Budweiser in a 1:4 ratio and get a nice tasty beer! BTW, it may take a while to ferment out, so we'll delay the party for 3 months or so. ** Jim Busch wrote: >>GRMarkel writes: > ><Looking at my Zap-Pap I figured I have a ><pretty good filter bed of spent grains, it is still warm (140 deg.) so >should ><be free of bacteria, just haven't had the nerve to pass a finished batch ><through the grain on its way to the carboy. > >No, no.

Only problem Call me a worry wort, but I wouldn't use your lauter tun as a hop back. The original statement "it is still warm (140 deg.) so should be free of bacteria" scares the heck out of me. The grain carries a load of bad bacteria, which is why grain should be milled away from your fermenters. The heat *may* kill the bacteria, or it may not. The fact that it is a Zapap (many holes drilled in plastic) makes me even more nervous about it. Just think of all those scratches and grooves for bugs to hide in! I don't think you really can, as Jim says, "sanitize your Zapap". Well, of course it can be done, but great care should be taken. Yes, the heat of the hot wort *should* kill any bacteria it comes in contact with, but if it is being immediately chilled then the bacteria could conceivably survive into the fermenter. Like I said, you can call me a worry wort. I'm all for hop backs, BTW, but I'd make a separate vessel for a hop back. Cheers, Norm Return to table of contents
Date: Thu, 13 Jul 95 17:07:00 EST From: phiggins at randomhouse.com Subject: Steam Beer Fermentation Temp Dear HBD, I've just made up my first batch of steam beer which has been fermenting away nicely now for 5 days at around 70 degrees. From what I've read, I should give it another 3 or 4 days and then rack to the secondary and continue fermenting at 45-50 degrees for another week or so. The problem is, I don't have the capabilities to keep 5 gallons of beer at 45 degrees, unless of course I throw out all of the food in my fridge (which I've considered). My question is, if I rack to the secondary and continue fermenting at 70 degrees, will this greatly effect the flavor? Or, immediately after bottling if I were to place the bottles in the fridge and condition at 45 degrees, would this work? Send responses via private e-mail and I'll post a summary of all responses. Thanks in advance. Beer is our bond. Patrick Higgins phiggins at randomhouse.com Return to table of contents
Date: Thu, 13 Jul 95 14:05:02 -0700 From: robtrish at noif.ncp.bc.ca (Rob Lauriston) Subject: bomb scare and brewery dangers In # 1779, Charlie Scandrett <merino at ozemail.com.au> writes > Never make your own pressure cooker, steam is the most dangerous of gases, it blows your head off AND cooks you! Please use expert advice with pressurised steam or HBD will need an obituary column! Charlie, you scoundrell, now why did you have to ruin the good info with this extremism? Even CO2 can be more dangerous. You shouldn't do ANYTHING without being aware of potential hazards. (Plugging in a shaver in the bathroom, crossing the street, consuming alcohol, using compressed CO2 cylinders, getting married, having kids...) I would be more worried about hot water under pressure because of the potential for it to flash into steam. Because steam is so widely used, the one in a million accident has happened lots of times, so it is regulated to avoid more accidents. Be aware of the danger, but don't go overboard with paranoia. Some other brewery dangers that apply to homebrewers and micros (you mentioned pilot brews) are: - --- Boil overs. That hot stuff coming out of the kettle is as bad as steam. Imagine in a micro with waves of boiling bubbles rolling across the floor... I was alone in the brewery at 3am. Boil-overs were rare but it happened on this batch of stout. I'm below the operating level of the brewhouse and I hear - splat, splat. So I run up the stairs through the dripping gops and hose it down, but not without having this stuff land on my head. - -- Now imagine that your boil over has extinguished your propane burner. Gas accumulates near the pilot on the furnace or hot water heater. You thought you had adequate ventilation, but BOOM... - -- You're big into imitating commercial practice. So you have some caustic soda beads (anhydrous sodium hydroxide) and your going to make up your cleaning solution. Some of the powder on the outside of the bag rubs off on your skin. After a while, Yeowee. You know that it will clean better hot, so you add the stuff to hot water. VaVoom, talk about in your face. Now I know what exothermic means! - -- you are going to de-scale your precious Cornelius kegs, because you just can't figure out where that off-flavour is coming from. So you have some acid in there. Or you use peracetic acid to sanitize the stainless. But you're still using bleach on your carboys. Now you didn't mix the acid and the bleach directly, but in your drains... (So how much of a danger is this?) I hope all of this makes brewing more exciting for all of you. Don't want to be *too* relaxed, not worrying, having a homebrew. Reminds me of when I was a kid, building bombs out of homemade gunpowder and pieces of ski-pole. Electronic detonation with iron framing wire between copper leads... Good thing we decided against soldering the pipe-bomb shut after the gunpowder was in it...

I agree totaly. As a person who has been lucky enough not to do this, I say ignoring this contraction of beer, and sucking up of your airlock solution could be disaster. Every year at our club, one meeting a year is devoted to screw ups. We do this so the newer members will not repeat our old mistakes. Last year my friend Joe missed this meeting. Another member Fred admitted to haveing bleach water suck into the carboy though the blow off hose. Two weeks later Joe made the same mistake. The result Bleach Beer. I also agree with Al that the Percentage of air in the Carboy would have a large part to play. I have seen Warm extract brews, IE 90 degrees, suck a Size 6.5 inch stopper through the neck of a carboy. Also I've seen pictures of Professional fermenters that have imploded inward due to having the air inside cooled to 32 down from 60 degrees. 10 guage stainless being as strong as it is I would say that one hell of a vacum. As a final thought if you want to make sure this doesn't happen to you spend an few extra bucks, and make your blow off tube 9 feet long. John Majetic PS: Thanks for all the Judgenet Tips. PPS: The club screwup theme also makes for lots of laughs. Return to table of contents

Kenneth K Goodrow, <goodrow at orion.etsu.edu>, wrote (possibly after having had one too many American Light Lagers ;^) > Personally, discussing hops can be quite enlightening, but hops alone > can be dull as hell. Ouch! You know I try to be more interesting but...say, has anyone tried the newish high-alpha hop, Columbus? I really like it in big ales (IPA, BW, etc). It's become my new all purpose bittering hop, although I still use Nugget on occasion. Full Sail's Old Boardhead and Sierra Nevada's Bigfoot both used Columbus this year (I think). Oh yeah, strive for "variety". Um, er, I just got a sample of a new Goldings-type hop from Mark Kellums. It's called Midlands Golding; any of you Anglophiles heard of it or used it before? I'm going to make a tea with a little bit and check out the aroma/flavor characteristics. Oh, damn, hops again. Maybe I better just stop. Glenn Return to table of contents

I tire of Christians everywhere shoving their stupid opinions down my throat everywhere I go in this life. Go jump in the lion pit where you belong. I close the door in your face every Sunday when you harass me in my own home. As all the rest of us know, there is just one deity... BEER!!! There are also 4 lesser deities: those of Malt, Hops, Water and Yeast. There are also many lesser pretenders to this title, such as Sugar, Rice and Corn. As always, opposites must co-exist for equilibrium. Yin vs. Yang. Man and Woman. Black and White The struggle BEER has is with the demons Oxidation, Bacteria, Astingency etc. This is a never - ending struggle. It is the goal of brewers everywhere to banish these demons to the depths of Hell. This is easier for some than for others. For YOU out there who have trouble with these demons, PERSIST! We are all together in this deadly battle. We need all the help we can get. BREWERS OF THE WORLD UNITE!!! ******************* Jobbie from Sydney ******************* PS.

Date: Thu, 13 Jul 1995 18:52:46 -0400 From: TRoat at aol.com Subject: HBD Archives & Mold Q1: I can not seem to successfully decompress the HBD archive files. They have .z extensions (Lempel-Ziv encoding) but the ZOO program I was told to use keeps telling me ALL the HBD asrchive files are corrupted (fatal error). I'm dying to open the old textbooks to learn, but can't. Any step by step help or other software advice would be greatly appreciated; that way I can quit banging my head on the wall and get back to drinking homebrew while learning about it. Q2: Have a batch of Palalia Pale Ale in secondary; been in there for 2 weeks. However, there seems to be, well actually there is, mold developing on the surface of me lovely beer. The mold spot is about the size of a bottlecap and whitish. Ouch. In Ohio the heat index is 100 degrees, makin my kitchen where the beer sits about 80. Fermentation was over about before I transfered to secondary and before this awful heat hit. Is this beer apocolypse? Is there any hope? Is it like cheese, just cut off the mold (i.e. dont bottle the moldy part) and the rest remains unaffected? I'm low on bottles and don't want to waste 35 bottles on a "slim chance of survival" batch. Thanks for your collective insights. Todd (Cincinnati, Ohio) P.S.: I'm practicing my "Paging Down" skills and stealthily avoiding the Religion thread as many suggested. Return to table of contents
Date: Thu, 13 Jul 1995 19:32:37 -0500 (CDT) From: Kenneth K Goodrow <goodrow at orion.etsu.edu> Subject: "bleachy" residue... Rick Gontarek wrote about a white precipitate that formed overnight when he was letting his equipment soak -- a fermenter as I remember. Well, I had the same problem with my racking tubes -- white precipitate formed on the inside and it was a real pain to get out, though it seems that it is not all out. I forced one end of the tube (my favorite on) onto a jet bottle washer and cranked the faucet on the highest and hottest I could get. Most of the stuff cleared after I rolled the tube between my fingers, but not all of it. I didn't give a flying Calvinist, so I used the tube anyway (while drinking a tall cold 22 ouncer, of course, to curb any unclean-tube angst) and the beer seemed to turn out excellent. My theory is that there was too much bleach in the cleaning solution and that I left the equipment soaking for too long. Either way, the beer tastes great and I think I might put the residue down as part of the recipe. By the way, for those of you who don't like spending money on wine making but don't mind a glass now and then, here's a great recipe (and very cheap) I got from an old farmer at church a few months back: 2 cans Welch's grape juice -- unsweetened (but it really doesn't matter) Gallon of water 3 cups table sugar 1/2 teaspoon dry baking yeast (Fleishmans, etc.) Mix the above in any order and let set in a fermenter or whatever else you choose until fermentation is visibly done. Double, triple, or whatever, as desired. The stuff tastes great! Very fruity flavor chilled and a great table wine. You'll be surprised. Great recipe for your teenaged sons or daughters. ha ha Cheers! Kenn Return to table of contents

Is there any reason not to split my grain bill equally between both coolers??

Date: Thu, 13 Jul 1995 22:34:48 -0500 From: ajdel at interramp.com (A. J. deLange) Subject: Edinburgh 3 Edinburgh 3 This is the tenth in a series of posts on the formulation of waters similar to those of famous brewing cities of the world. They are based on ion concentration profiles given by Dave Draper in his post in #1704 (10 April 95). See my post "Water Series" (#1763) for explanatory material (correction: in the Line 3 explanation read 1.8 ml of 1 N sulfuric acid, not 18 ml). Quick reminders: all ion concentrations and salt quantities are in ppm which is the same as mg/l. The water to which the salts are added is assumed to be ION FREE (i.e. it is DISTILLED WATER or REVERSE OSMOSIS WATER). The Edinburgh 3 profile was taken from Noonan's "Scotch Ales" with values for each ion being the middle of the range of values given in the table on p 104. This profile is accurately synthesized using the minimum salt set with a modest amount of external acid: Formulation I n: 820000 Temp: 0.000988 Energy (rms %): 0.039940 Edinburgh 3 Desired Cations: 7.340 Anions: 5.606 mEq/L Ratio: 0.764 ION WT DESIRED REALIZED ERR, % SALTS AMOUNT Ca 1.00 100.000 100.036 0.04 NaCl 20.364 Mg 1.00 18.000 18.003 0.02 Na2CO3.10H2O 0.000 Na 1.00 20.000 20.019 0.09 CaCL2 0.000 K 1.00 0.000 0.000 0.00 CaSO4.2H2O 60.669 CO3 1.00 160.000 160.034 0.02 CaCO3 214.547 SO4 1.00 105.000 104.980 -0.02 MgCL2 0.000 Cl 1.00 45.000 45.002 0.00 MgCO3 0.000 H 1.00 2.658 0.921 -65.35 KCl 0.000 Na2SO4 0.000 MgSO4.7H2O 182.477 H2SO4 0.000 NaHCO3 43.883 HCl 33.591 Carbonic: 0.5156 Bicarbonate: 2.1493 Carbonate: 0.001029 mM Total Required Hydronium: 2.6581 Sulfuric Hydronium: 0.0000 mEq Hydrochloric Hydronium: 0.9211 mEq 1.7370 mEq additional hydronium required to maintain pH 7.00 Solubility Products - CaCO3: 8.70E-09 MgCO3: 2.60E-05 Ion Products - CaCO3: 2.57E-09 MgCO3: 7.62E-10 Alkalinity: 2.12 mEq; 106.19 ppm as CaCO3. Temporary hardness: 5.33 mEq; 266.59 ppm as CaCO3 Permanent hardness: 1.14 mEq; 57.03 ppm as CaCO3 The required external acid is modest. If you choose to use CO2 as the external acid aeration to pH 7 will result in approximately 270 ppm carbonate. It is necessary to aerate to around pH 7.45 to get to about 160 ppm carbonate. As a practical matter the external acid, of whatever type, can be ignored. If we make up this formulation without use of any external acid not all the calcium carbonate dissolves (actually about half of it) and we wind up with a cloudy mixture at pH 7.8 or so. Upon adding malt the pH immediately drops because of the of the malt's buffering capacity . In an experiment we did with Ireks Pilsner malt the ratio of malt to water was about 1 pound per quart and the pH immediately dropped to 5.68 (when distilled water alone was used the pH was 5.60). Thus the malt has plenty of extra buffering capacity to cover the lack of external acid. What of the CaCO3 that didn't get dissolved? The data from Formulation I show that we are below saturation at pH 7. Now we are at pH 5.7 at which the ion product would be even less because the distribution of ions shifts away from carbonate and towards carbonic at the lower pH. Further, if the temperature is raised to the range where phytase is active (around 100F) calcium will precipitate from solution as phosphate by reaction with phytin. This makes it even easier for the remaining chalk to dissolve, only to be precipitated later as carbonate and phosphate during the boil. This fortuitous set of circumstances is due to the fairly high chlorine con- tent of this specification. Most of the chlorine in our formulation comes from hydrochloric acid which not only supplies chlorine but neutralizes much of the alkalinity associated with the calcium. Only an extra 1.7 mEq/L is required to get to pH 7. Even Pilsner malt can supply this much and then some. Noting that Scotch ales usually include some roasted barley which is quite acidic we can recommend this profile as the easiest and best (of the 3 Edinburgh profiles) for use in brewing beers like the Scotch ales of Edinburgh. Note that the lighter beers of that and surrounding cities use softer water. See Noonan. A.J. deLange Numquam in dubio, saepe in errore! ajdel at interramp.com Return to table of contents

You are only dooming yourselves, the net/beer Gods purposely extend a thread that much longer with each complaint. Your best bet is to ignore or start up a more interesting thread, such as: Wort Chillers, how can anyone complain about such a great gadget. And easily constructed from supplies from any local hardware store. I'm in love and plan to drag this one around the block a few more times. I don't know if my names are the most suitable but here are some other considerations from what I've seen so far. In line chillers(Incremental) CF-counter flow PCF?- chamber counter flow would be better-CCF or CC? BI-?Bucket Immersion,? -Bath chiller, coil immersion PC-plate chiller, Bulk Chillers PI?-Pot Immersion? -just plain old immersion would be the easiest, No? BC-bulk chiller DC-Dump or Newbie chiller Coolants TC-tap cooled IW-Ice water bath RI-Recirculating Ice bath, for In line chillers Also: Pump or Gravity fed would be a consideration Don't get me wrong a complicated naming system would be ridicolous. I am just interested in semi-agreeing on easy to live with descriptive names. Atleast for chiller configuration, so as to ease talking about them. Rob Lauritson asked about counter flows without a pump. Count me as one user of gravity. I always assume that due to the extra expense no one would use a pump unless the situation called for it! Most of you use Iodophor to sanitize don't you? I am steam sanitizing and it has worked well so far. Originally I tried cleaning with boiling water, 1 gal sour mash anyone.:) Campus Brewing, I was tossing the idea around last semester. Probably will consider it again in the fall, don't know how far past the planning stage it will get. The AHA has info and a net site about starting a club, that would probably help out. Also the local HB shop around here will give a talk and door prize for large enough groups, you could try that out. False bottoms, I figure the pizza plate jobby would work. I use 5ft of coiled and slotted Cu tubing that works well and costs next to nothing. The Zapap style seemed slow for the extensive number of holes I drilled. Maybe the fact that the slots in the tubing are facing down means the grain rests beside and has less chance to fill the holes? YMMV but the pizza mesh sounds good to me keith. Rick is your new water hard? MY water is pretty hard and has precipitated out white stuff with very long bleach sanitizer exposure. Couldn't get it off for love or money. Then I just used the old hard water standby, a little vinegar and it lifted right off. See Ya, Rob P.S. any thread to do with homemade beer gadgets is alright with me.:) Return to table of contents

Yankee Magazine has been doing this with bed and breakfasts for some time. It seems to work reasonably well. Some things to check may be: 1) Is there an agent listed? Check the agent's reputation with local boards. 2) Is a minimum number of entries required? If the minimum number of entries isn't reached, what happens to the $100? In the b&b essay contests, for instance, it is refunded. In the case of the b&b contests, the general advice has been to check out the property as if you were going to buy it outright. If you would be prepared to buy and operate it, realize that you would spend more than $100 in non-refundable application fees and the like to see if you qualify for a loan, to hire a lawyer, etc. Looked at in this way, it's actually not a bad investment. Realize that you are essentially competing against 1,000 or more other "bidders" and act accordingly. A co-worked of mine entered one of the Yankee magazine contests. She didn't win but doesn't regret the money spent - she is actively pursuing a B&B and spends at least that much when she gets a lead on one she wants. Disclaimer: this still could be a scam, of course. I wouldn't judge it based solely on the format, though. ******************************************************** Kevin (kpnadai at adsnet.com) asked: > Subject: Campden tablets > > I was wondering why Campden tablets aren't used in homebrewing as they are > in wine and mead making.

You can culture the yeast from the bottle (at least I did). Boil up a pint or so of 1.040 wort, cool it to room temperature, add it to the bottle (after flaming the lip and pouring off the beer). Stick an airlock on it and in a day or two you should start to see some activity. After it ferments out, you can make a larger starter, or just pitch it into your wort. Mine took a couple days to get going. I don't know how long a '93 might take. Note that this yeast produces a lot of esters if fermented at high temperatures. I just bottled a Belgian Pale Ale made with this yeast. We had a heat wave while it was fermenting and it has definite 'Juicy Fruit Gum' notes to it. It's still drinkable, and I'm hoping it will improve with age. I fermented in the 72-77 degree Fahrenheit range (22-25 C). Dr. Maribeth Raines recommends 65-70 (18-21 C). I've seen people recommend even lower temps, but you may have a long ferment.

I am about to put my new 1/2 barrel, 3-tiered, gravity feed system into operation. The BIG question is on the use of brass in some of the plumbing. I have 1/2" stainless couplings welded into the side of each keg wall, flush with the inside. I know exactly what type of design I want to plumb each vessel. However, would a minimal use of brass such as using a short brass nipple to connect couplings to (1) ball valves (on the outside) or (2) slotted copper ring (on the inside) destroy my beer? I plan to soak all brass parts in a vinegar/hydrogen peroxide solution that is supposed to remove surface lead. Anyway, most off the literature I have read says brass is OK, but some says use only stainless or copper. Right now I have a gleaming pile of impressive looking metal in my basement, but I don't want to make crummy beer with it by being a cheapskate. I have had a lot of fun going to the salvage yards and putting this stuff together; I'm ready to brew! Any suggestions? The FrankenBrewer Return to table of contents

He was actually showing that beer (especially unfiltered beer) has some nutritional value, like more than 100% of your daily requirements of some of the B-vitamins. Apparently, you can't say anything about beer being good. Andy Donohue brings up the subject of Nigerians brewing beer with alternative grains like sorghum. After reading this story last year, I attended a local sorghum festival and bought six pounds of sorghum syrup. I made a "beer" with it, using about 1.5 oz. of Cascade hops. While I'm sure that there is somebody who would have liked it (just like some people like spruce beer), it was not for me. Needless to say, it is now being used for things other than drinking. Has anyone else tried this? John ________________________________________________________________ Dr. John M.

Swan" <mswan at fdic.gov> Subject: Upside down trub I had a strange experience in my last brewing session and wondered if anyone had ever seen this before: I made a 2 1/2 gallon all grain batch of Munich Dunkle (3 pounds of Dark Munich Malt, 1 pound of two-row pale malt). After cooling, I poured the wort into a five gallon carboy to allow it to settle. (Specific gravity: 1.045) I also pitched the yeast (Wyeast American Ale, in a 25 oz. starter) at the same time. Although I tried to strain the wort through the whole hops, a *lot* of hot and cold break material made it into the carboy. In the past, I waited a few hours for the wort to seperate and then racked the clear wort off the trub and pitched the yeast at that time. In order to aerate the wort, I shook up the carboy several times during the first three hours. Each time, the trub settled to the bottom. However, the last time I shook the carboy, the trub rose to the *top* of the carboy above the layer of clear wort. This seemed to correspond with the first visible activity of the yeast. Does anyone know why this happened? I decided not to rack the beer off the trub. Within 8 hours, fermentation was vigorous and about half the trub had settled to the bottom. IMBR? :-) Is this related to the "Bowtie effect?" Thanks in advance. Mike Swan Dallas, Texas mswan at fdic.gov "Standard disclaimers apply" Return to table of contents

The HBD Oracle has considered your question deeply and answers thus: No. But there is no hope for those items that have come in contact with it. To make the suburban run better, forget the priest's blessings, and apply the homebrew directly to the engine - I suggest a 1:1 mixture of homebrew with your regular fuel. As for yourself, the Republican, Harry Winston, and any members of your family, the GOP, and/or the Vatican, you must remember the old adage that "Alcohol and gasoline do not mix". Straight gasoline, however, really isn't too bad, and makes a refreshing and stimulating libation. After all, it works for Jose Quervo! You owe the Oracle one keg of homebrew.

Sorry Ray, I disagree on this one. I believe that judges need to complete their evaluation and comments before discussing a beer. However, judges need the option to discuss a beer before "completing" the scoring. Otherwise large scoring differentials are guaranteed. I believe that there exists no single objective score for a beer. The scores should only be used as a relative ranking tool. At a higher level, there is a single scoring range that a beer should fit into.

The grain sorghum used to brew African opaque beer is malted. The adjuncts used in the brewing process (corn grits and millet primarily) are indeed unmalted. An interesting sidelight to the situation in Nigeria is that Guinness developed a special formulation of its Foreign Extra Stout which uses malted sorghum in place of malted barley. Nigeria is the only country in the world where this formulation is used. I hope to sample this stout during an upcoming trip to Africa in search of indigenous beers.

Nope. The political affiliation of the former owner assures the quality of your brew. Even better, *IF* the former owner listened Rush Limbaugh on the Suburban's radio, you may have some *really really good* beer there. Were I you, I'd garage the Suburban and turn it into a brewery. And later on in the post, LimaWiskey at aol.com continues - this time regarding slate fermenters (which I think is pretty cool): >The use of a porous (sp) masonry cement for binding the edges is causing >some concern. Can you "finish" the joints by sealing with food grade (if there is such a thing) silicone caulk? If you're considering finishing the entire inside of the fermenter, how about some sort of glaze compound? I also know there are clear finishes for wood (not sure if only for wood) that are food-grade (once used one for a wooden salad bowl). -Tim Tim Fields / Vienna, VA, USA / timf at relay.com Return to table of contents

The main reason not to use spent grains as a filter before your cooling is that it will leach a buttload of rude tannins into your beer.

The lead solder is more active galvanically than stainless steel and will corrode prefernentially when in use. ie. dissolve into the beer. I would check and see if it is Lead, I really would not think it would be. Check its hardness, is it soft or pretty hard? It might be silver solder which would be okay. If you can, scrape off a shaving with a knife and take it to the Lab at the university for a Scanning Electron Microscope, Energy Dispersive X Ray Analysis. (SEM EDX, pronounced Sem Edax) EDX will be able to quickly tell you what elements are in the solder. Dont plan on using it if it has Lead or Cadmium in it. Fixes: 1. You could look for an epoxy primer or epoxy based paint that you could paint over all of the solder joint that would contact the beer. 2. Contrary to what you were told, you can have it welded, provided that it is indeed a 304 type stainless. There is no reason that abrasive cleaning shouldnt make the steel clean enough to weld. But those solder joint need to be cut off as they would contaminate the weld. Come to think of it, thats probably what the guy was refering to. You should be able to get all of it off by hard filing though. Take a sample of the steel for EDX to see if it is a weldable type. All you will need is a tiny chip or sliver. The size of a fingernail clipping is plenty. Since you wont be actively heating this whirlpool, I would try finding a food grade paint to coat the joints with, that would be the easiest fix. John J.
