---------------------------------------------------------------------- Date: Tue, 6 Jan 1998 09:56:05 -0600 From: rlabor at lsumc.edu (LaBorde, Ronald) Subject: Plastic RIMS From: Jim Wallace <jwallace at crocker.com> >>>> ................From: rlabor at lsumc.edu (LaBorde, Ronald).............. I use an Igloo 10 gallon round cooler for my mash tun and would like to mount a dial thermometer into the side. Has anyone any advise on how to do this?<<<< >>Don't do it.. A fixed thermometer in a mash tun is most like to give you some very deceptive information.. I find it essential to have a long stemed thermometer to move around while changing to a new temp rest. When I get similar readings all over I know the mash temp is stable. A single data point wont do it. be real careful here!!! << Ok, I failed to mention that I use the RIMS system and re-circulate the mash. I am currently inserting a small dial thermometer by hand into the mash and read the temp. It is my hope and understanding that the re-circulation tends to even the temperatures throughout the mash. One question I have about re-circulation is: Can I re-circulate while stirring the mash? I am using for a false bottom, a somewhat unknown SS screen, one piece, that fits very well into the bottom of the Igloo cooler. It is made by the same company that sells Iodaphor. The price was right, and it's strong enough to stand on. - ------------------------------------------------------------------------ - ------------------------- From: "Lee, Ken" <KLee at resdata.com> >>Subject: Converting 10 Gallon Gott to a RIMS I have been using my 10 gallon Gott cooler as an infusion mash/lauter tun, and am interested in learning how I can convert it to a RIMS system. I have seen a picture of one, but never seem explicit instructions on how to do this. If any one has done this or knows a web page/article that describes how to do this in detail (diagrams, parts list, etc.), would you please let me know! I am not mechanically inclined, I just really like to tinker with this stuff!<< Well Ken, check with your wife first, then if you can get a couple of pumps, you can build a very nice RIMS system for not too much money and difficulty. Mine uses an Igloo for the mash tun. Uses a 15 gal. HDPE plastic container for the HLT Uses another 15 gal HDPE plastic container for the boiler. I heat both the HLT, and the boiler with 240volt 4500 watt electric heater elements. I built a power controller for the elements so that I can turn a knob and smoothly vary the temperature from off to full power. (using 555 timer IC circuits and SS relays) I have all three on the same level, on a 18 inch high cart on wheels - a simple chrome wire cart I ordered from a catalog. Looks good - works good. I re-circulate through a 25 foot coil of soft copper tubing thrown into the HLT, no mounting, really just thrown in. I controll all temps manually. The use of two pumps allows me to have everything on the same level. No ladders for brewing, Just painting. Propane only when I do a decoction, or grill some peppers.

Date: Tue, 6 Jan 1998 09:55:56 -0600 From: "Wills, Frederick J (MED)" <Frederick.Wills at amermsx.med.ge.com> Subject: 10g. Gott RMS / MM vs RMS / Zapaps "Lee, Ken" <KLee at resdata.com> asks about converting a 10 gallon Gott cooler to a RIMS system. There is much good information on the web about various peoples' RIMS setups. I suggest that you do a search on "RIMS, brew & mash". Since you already have some kind of false bottom for your cooler mash/lauter tun you are all set there. In reality, what we all have come to consider a RIMS system is actually 2 subsystems combined. The first subsystem and the more important one IMO, is the wort recirculator. All that you will need additional to your mash/lauter tun is a wort pump, flow regulating device (ie ball valve) and an on-off switch. One could do true hot water infusions while pumping and get similar results as those from a "full blown" RMS. Come to think of it this would be a real R*I*MS, right? The advantages of recirculating the wort are: temperature uniformity throughout the grist, maximum uniform enzyme mixing, minimum particulate material in brew kettle via filtration. I asked for some advice a while back about a means for regulating the flow (ie electrically via motor speed control or physically with ball valve). The nearly unanimous answer was (assuming the use of a magnetically coupled pump) skip the speed control and use a ball valve. I am doing this and the motor runs very cool during the entire mash. The second functional subsystem is the wort heater and temperature regulator. Typically you will see similar designs using electric hot water heater elements plumbed into the wort's flow path during recirculation. This probably because it is very convenient way to add heat to the mash regardless of the container used as a tun. The temperature controller could be just an on/off switch and attendant carbon based switch actuator (ie you have to turn it on and off) but after having done a mash this way when my electronic regulator was on the fritz I can tell you it is a PITA. There are several varieties of controller out there and I again encourage you to search the web for ideas. Mine is of the homemade design a 'la Rodney Morris' schematic. The advantages of the heater and temperature controller are just that: precise temperature control, automatic maintenance of rest temps, ability to raise temps (step mash) without diluting the mash from optimum thickness for enzyme efficiency. I think that the optimum configuration for functional RMS brewing is having both subsystems automatic temperature regulation. I don't personally don't think that being able to preprogram the entire mash schedule via a computer interface is either necessary or cost effective, but YMMV. ********************** WRT the MashMixer as proposed and presented by Jack S, while it seems to be a useful approach to semi-automate mash *stirring*, IMO it does not seem to be as effective a solution as an RMS (Recirculating Mash System - Infusion or otherwise) . The MM system has no inherent means of: 1) maintaining rest temps, 2) boosting temps without either infusing or mashing on the stovetop or 3) filtering the wort as is normal in the full blown RMS system described above. Others have also noted the possibility of HSA due to air being sucked into the mash which is certainly not an issue with an RMS. *********************** Adding to the discussion on how to make a better Zapap. My first lauter tun was a modified Zapap model. I encourage anyone thinking about all-grain brewing to experiment with one of these since you are uncertain about your future as an all-grainer and this design can be made for pennies. Go to the donut shop and scrounge 2 identical buckets of at least 5 gallon capacity. Never pay for buckets as there are bazillions of them being sent to landfills daily. Drill as many of the smallest size holes possible in the bottom of one of the buckets. NET - WARNING - this has been known to drive people (alcoholic or not) to drink, ...but if you are trying to brew beer with this thing then you already know that! Never-mind. Next, cut the sides of the just drilled bucket (all the way around) about 2-3 inches up from the bottom. By cutting the bottom of the bucket off you will form a nifty false bottom which can be jammed nearly all the way into the other, still whole, bucket. This will cut down the amount of foundation water needed. More importantly this will prevent the possibility of over filling the inner bucket and having the mash ooze out from between the two buckets onto the floor. It will also prevent sucking air through that crack should you later retro-fit your lautertun with a RMS pump. The last improvement I made (similar to the soldering iron technique) was to flame buff the "false bottom" with a propane torch to melt any burrs left from drilling. Deburring makes it a heck of a lot easier to clean-up post mash. Just be very light handed with the heat so as not to make a molten mess of the plastic since you just spend many tedious minutes drilling it out. Also, need I say it? Be careful with the torch. Don't burn down your house. Yady- yady ya. I guess in summary: there is more than one way to shuck a feline, ... or a barley granule. Cheers, Fred Wills So. NH Return to table of contents
Date: Tue, 06 Jan 98 09:59:01 CST From: chris bersted <CTB967F at VMA.SMSU.EDU> Subject: bottle labels Ken Schwartz, in respoonse to Dave Thomson's inquiry as to bottle labels suggested he used Print Shop and commercial xeroxing to produce labels that don't smear. I have found that while bubble jet color output does normally smear, a quick spray with an acryilic spray designed to protect photos makes labels much less likely to smear. In my case, I often use photos scanned in on a cheap scanner, and then use columns in Wordperfect to proudce typically six labels per page. By using photos, one can personalize your beer. Examples: picture of my daughter and son-in-law called "celebration porter" served at their wedding reception; picture of my wife soaking her feet in creek after 16 mile roundtrip hike to upper meadow of Slough Creek in Yellowstone called "Tired Dogs' Imperial Stout", etc. I concur with using a child's glue stick to attach labels, since sanitation heated drying in dishwasher typically causes labels to drop to bottom of dishwasher (do not use rinse agent) Chris Bersted ctb967f at vma.smsu.edu Return to table of contents
Date: Tue, 6 Jan 98 08:16 PST From: cburns at egusd.k12.ca.us (Charles Burns) Subject: Dangerous Dave's Dunkel - Update The "House Flavor" otherwise known as carmelized then carbonized second decoction has turned our Barrel 'o Dunkel into a Rauch-Dunkel. This is a call for discussion on an addition to the AHA Style Guidelines;-) Similar to Steinbier in that we can produce this beer only through a specialized process (soon to be patented as "Dave's Carbonized Decoction, or DCD") as opposed to a particular grist/hop bill. This Dunkel (see previous hbd's for "Barrel 'o Dunkel" recipe) now has a distinctly smokey flavor. While it requires us to stretch the style definition of a dunkel, it really is quite pleasant. My 12-16 oz of Wyeast 2308 reduced my 6 gallons from 1.060 to 1.013 in only 5 days (56F, I know, too high). Racked and tasted it on Saturday and was surprised by the smoky malty flavor. Charley (making smoked beer without smoked malt) in N.Cal PS - I just thought the digest needed some frivolity for a change, its getting awfully serious with non-brewing related stuff lately.

Date: Tue, 06 Jan 1998 11:07:32 -0500 From: Spencer W Thomas <spencer at engin.umich.edu> Subject: Re: Second all-grain brew and newbie questions You can drop the next batch right onto the yeast from this batch. But I wouldn't do it more than once. There is stuff in there other than yeast which could affect the flavor of your beer if allowed to accumulate. The "best" way to harvest yeast for *ale* brewing is top-cropping. This requires that you use an "open" fermenter -- one which you can get a large spoon into, at least. You don't have to ferment with the top off, it just has to be removable. My procedure for top-cropping (copied wholesale from Jeff Renner, of course): When the foam starts to mount in the fermenter, I skim the "crud" about twice a day. After a couple of days of this, or less, you should have a nice, clean looking head. After two or three days, the head turn yeast-colored (tannish) and compact a bit. At this point, you can start harvesting yeast. Take a sanitized (preferably sterilized, but we do what we can) wide-mouth jar ("Mason" jar in U.S. canning terminology) of at least a pint capacity and a (similarly) sanitized metal spoon. Skim off the "thick" parts of the head, and pour/drop them into the jar. Put the lid back on the jar and store in a cool place or the fridge. Do this a couple of times per day until fermentation has stopped or you've got as much yeast as you want (at least 4 ounces of yeast "paste" in the bottom of the jar is good). Stick it in the fridge until you're ready to brew the next batch. It'll easily keep a couple of weeks. At brew time, you can "wake up" the yeast by pouring off any liquid from the top, adding a bit of starter wort, and swirling or shaking the jar to resuspend the yeast. See http://www-personal.engin.umich.edu/~spencer/images/starter-wow.jpg for the result. Four ounces (250ml) of thick yeast paste is plenty to start a 5 gallon batch. It should be visibly fermenting within a couple of hours and really roaring along within 8 hours. =Spencer Thomas in Ann Arbor, MI (spencer at umich.edu) Return to table of contents

Date: Tue, 06 Jan 1998 08:20:00 PST From: "Gregg Soh" <greggos at hotmail.com> Subject: Diastatic Enzymes - How much? I've got a question about the enzymatic power of the malts that we use. There's lots that have been said about how 6-row has more enzymatic power than 2-row and how wheat malt is less diastatic than barley malt. But how much can we actually expect the malt we use to convert other non-enzymatic constituents? Charlie P. says 6-row can convert 30-40% extra over. Others say make the malt up to 50% of the total amount of grain, while others say adjuncts should not make up more than 45%. This can be a little hazy as the non-enzymatic components will have very different 'amounts' that will be converted to sugars and dextrin. So even though one might try to follow these ratios and percentages, one might ultimately ask whether this should be by weight of total grist or by points of extract(or something similar) to aid in recipe designing. Does anyone have a "rule-of-thumb" ratio that he/she uses to provide the necessary amount of diastatic malt? While I'm into that, how much can 2-row malt convert? Is it right to assume wheat malt should only be used to convert itself?

Or perhaps a industrial paint stirrer would fit the bill? I recall paying about $10 for a half dozen different sized fan blades from American Science Center. I think the one I ended up using was $3. On the other hand, a quick look through the McMaster Carr catalog in the "industrial mixer" section will give you pause. Not knowing any better when I first got into this, I paid $40 for a 3" one.

I suspect that you will also find that only in the US is the emphasis on: "I can't do this without god's help". Not only is this totally destructive to the development of ANY self-control but as a born-again Atheist, it creates an impossible choice. It also makes the meetings about as useful as a revival meeting and again sets up the impossible choice..... Go and lose control or stay home and work it out alone. From: rlabor at lsumc.edu (LaBorde, Ronald) Subject: RE: Mixmasher "I still need to stir in the grain, (with RIMS)... Brings up another intersting point. With the Mixmasher running in the brewing water (at whatever temp one chooses to start) one simply pours the grain in slowly as the Mixmasher does the perfect dough-in. Ironically, this has become the most "tedious" part left in my process. How easy it is to forget how really tedious it was when I also had to stir it. ..................... Some more thoughts on HSA. I have always been troubled by some facts that seem to be in conflict. We have to oxygenate the wort because the boiling drives off the oxygen. We have the basic fact that the hotter a liquid is, the less oxygen it can hold. As we heat the liquid, oxygen escapes to the atmosphere. However, if we stir it while heating, it will somehow absorb so much oxygen that it could ruin our beer. ................. Finally, a hearty thanks to all for the kind words of support, if not for me personally, for the far more important and hard to hang on to, trophy of free speech. I think we have all come a long way in the years over which this group has evolved. Wonder how many remember that (un-named) fellow who actually started his own list, the sole charter of which was to make it "JS exclusive". I tried subscribing but was "automagically" rejected. Pray tell, is he still around? Sort of sad that as a Brewer of the Year or some such trophy, he had a lot to offer the group. If you want to read what I think is possibly the funniest posting ever on the Digest, go to: http://hbd.org and search for "Godzilla" 1992. Don't know what happened to Chris Campanelli but his prediction at the end has pretty much come true aside from the fact that instead of playing bridge, our wives compare notes on their wierd husbands.

Joe Kung-Fu Grip" so useful for transporting glass carboys, I had a thought... One could apply the "fifth force" (duct tape) to a carboy to help prevent it from disintegrating if dropped.

Date: Tue, 6 Jan 98 12:55:34 CST From: jwilkins at wss.dsccc.com (John Wilkinson) Subject: alcoholism I didn't want to comment on this thread but gave in. I will try to be brief. I agree with Jack Schmidling in that it is the alcoholic's (whatever that is) responsibility to limit or eliminate alcohol to avoid problems. It is not Jack's problem, nor should it be ours, to tell others how to live. I doubt seriously that anyone with a drinking problem is going to see Jack's opinion of regulating alcohol intake and go off on a life ruining bender. If someone knows they cannot handle alcohol it is up to them to take care of the problem, not mine, yours, or Jack's. If someone like Jack finds they can drink in moderation but another finds they can't, they each have their own solutions. I think calling alcoholism a disease is a distortion. I find definitions of what an alcoholic is very hard to pin down. By some reckoning anyone drinking more than two drinks a day is an alcoholic. By someone else's it is the guy sleeping in the park with an empty wine bottle in his hand. I am sure that the defenders of the zero tolerance theory would say that if someone can drink in moderation they are not an alcoholic in the first place. In that case, Jack is not in "denial" as has been suggested. Enough. Let's get back to brewing and away from social work.

After you gain experience with a few more brews, you may be more concerned with any hops and goop mixed in with the yeast. You also could, instead, take a bit of the yeast from the primary and grow it up to the pitching volume you would like to use for the next brew. This will lessen the trub and flavor alterations that may ensue from the leftover hops and etc. from the first fermentation. >Does it matter that I use the same yeast that I used for the bock? Or >should I get some more yeast started for my next brew? (This seems like >a silly question, but I am unsure.) If your bock was OG way up there, say, 1.070 or so, probably you would need a fresh yeast. I have read that Dopplebocks, etc., wear out a yeast. I really do not understand this, I have really eaten a lot at partys and I wasn't worn out.!!!! Since you had a relatively normal OG, I would go ahead and reuse the yeast. >What are the problems >with Aluminum pots? I have not had any problems that I can iscern with >them, yet. I clean them real good after every batch, but I don't try to >remove the oxidation that has occurred from the exposure to wort and >water, though. Oh yeah, don't scrubb 'em. Then you have new exposed aluminum. You have done well not to remove the oxidation. There is not enough evidence to prove or disprove the use of aluminum in brewing.

Date: Tue, 6 Jan 1998 20:52:16 -0800 From: "Michael Kowalczyk" <mikekowal at megsinet.net> Subject: 10 Gallons of fun! I'm doing my first 10 gallon batch on Monday for free. Well almost. I reused parts that I had from 2 years of brewing and for cheap have come up with a way to do 10 gallons in place of 5. Here's how I plan to do it. Mash tun I mash in a 33 qt copper kettle. I can comfortably mash 14 lb with plenty of headspace. I plan on milling 20 lb and doughing in as much as possible (assuming a thick mash). I'm starting with 17 lb and will slowly add malt and water until its up to the top. If I get 18 lb. I'll be happy. Lauter Tun I use an insulated 5 gallon bucket and a phils phloating bottom as a lauter tun. Replace this with my 34 qt. HLT which is a rectangular cooler. I tried unsuccessfully to use the easymasher as a hop strainer in my kettle. Didn't work, so I had an easymasher laying around. Installed the easymasher in my HLT. Boiling Kettle (s) I was real paranoid a few months back when I made a beer that tasted like rust going into the fermenter. After examining my canning kettle I noticed gobs of rust. I sanded and used porcelain paint to touch up the spots. I was still leery and bought a new canning kettle. It turned out that the porcelain paint worked so now I have 2 kettles! By the way, the rust beer turned out fine. It may have been the hops I was tasting (at 2 am. tastes are off a little) Hot liquor tank. None. I'm planning on using one of my boiling kettles to have the first 8 gallons of sparge water. Then when the second canning kettle is freed up heat the rest of the sparge liquor. Procedure Mash as much grain as I can in the first kettle while heating sparge liquor in the second kettle. Transfer the grain to the lauter tun and immediately start heating the remaining sparge liquor in the freed up kettle. Collect as much runnings in my bottling bucket. Collect the remaining runnings in my other bottling bucket (the one I retired after 2 years of faithful bottling service). Transfer carefully with no aeration 1/2 and 1/2 from the bottling buckets to the kettles. My kettles go over 2 burners and just barely both fit on the stove. I'm using different hops in each kettle for variety, but am too lazy this time to use different yeasts. Maybe next time. I've never used dry yeast.... hmmm maybe this time to use the nottingham brand people talk about for one of the brews.... Yield Assuming 17 lb and my brewery I can get a 1.052 wort. People say that you get better extraction with larger batches so maybe I'll get 1.056 with 17 lb, or to really push the envelope 1.062 with 20 lb. Yield might be lower because I can't really apply my constant %87 efficiency to this lauter tun since I'm changing to the easymasher. May be some of that dreaded "channeling" I hear of will occur... maybe not. We'll see. Extra time I'm thinking it will add 2 to 3 hours to my brewing. Chilling is the biggest culprit. I have to do it serially. Also, I usually collect 1 gallon of runnings and start the boil right away. Since I'm collecting all of the wort first, then starting the boil I'm adding about 45 minutes. Still 10 hours for 10 gallons is still better than 7 hours for 5.... Open questions I'm not sure about the chilling. I can keep one boiling while chilling the other, but it takes me 45 minutes from the start of the chill to pitching yeast. I may turn off the burners at the same time, but leave one sit while I chill the other one. We'll see. I don't really have any questions, just thought I'd share a "brainstorm" I had after reading some posts on the HBD. Al K talks about not doing a secondary. I tried this technique and it works fine, so I don't need 4 carboys only 2. Al was taking about how he mixes his runnings for one strong and one lighter beer, so it got me to thinking about how I can apply these techniques to my system. Any suggestions or critiquing would be welcomed. Experimenting is fun! In 2 years and 30 batches I may have used the same setup maybe 3 times. God I live this sport! - Mike from Chicago.

In order to raise the temperature we can either a) heat the grain, in which case we're performing a decoction mash or b) add heated water, in which case we're step mashing. The methods and calculations for both are available from many sources, including back issues of the HBD. > "From one who mashes in an insulated cooler (aka Gott/Rubbermaid) > - doing so requires stirring.... > > During the entire mash? What is the point in using an insulated > cooler then? No, obviously there's no need to stir during the entire mash. I was simply responding to your statement that said "mashing in a cooler doesn't require stirring, and doesn't allow step mashing." It's obvious that you don't use one, or you'd find that both of those statements are patently false. And yes, I do walk away from my mash tun and watch a football game.

Date: Wed, 07 Jan 1998 01:41:30 -0800 From: "Olin J. Schultz" <beerx3 at ix.netcom.com> Subject: Same Recipes: Infusion versus step mashing With all the talk about ease of mashing with a mixmasher versus rims I would like to ask for the input of those in the collective who have done both infusion and step mashing with the same recipe. Recipes other than those with undermodified pilsner malt where a step mash may be needed for clarity. The reason I ask is that I have used both a mixmasher(ice cream maker motor, sanke keg shaft, stainless paddles) to perform step mashes and have of course done infusion mashing. I have seen rims but do not own one myself. I agree that for step mashing rims is great and a mixmasher is better than stirring. But what about good old infusion? In the battle of ease of use and simplicity Infusion pretty much waxes the mixer and rims and step mashing in general. Does not get much simpler than mixing the grist in and coming back 60 minutes(or whatever) later. So it comes down to what tastes better. With that said I have tried a few batches of the exact same beer with both step and infusion mashing schedules. I have liked the infusion mashed beers more. From a real, my own eyes and tastebuds perspective(not theoretical), I liked the infusion mashed beers more. The head retention was better and the body was greater(better control of the saccharification rest - one temp.) Granted I like beers with more body. Clarity is great. Runoff is clear after one pint with almost no particulate fall through.(3/32 holes on 5/32 centers false bottom in a 28 gallon s/s vessel with an underlet tube.) This is not an exhaustive testing by any means, just my experience. My question is if anyone else has done similiar tests. What has been your results? I think this would be really interesting. I feel that many people start step mashing because some book said they would get clearer beer and better head retention. I do realize that certain malts require it, although I have used DWC pilsner malt in infusion mashes with great results and no permanent hazes. Same for Weyerman Pils. Our club is going to do some tests, I would suggest this might be a good experiment for any club. Also would be interesting to know what percentage of commercial micro breweries do step mashing compared with infusion?

Date: Wed, 07 Jan 1998 01:55:27 -0800 From: "Olin J. Schultz" <beerx3 at ix.netcom.com> Subject: Trub Decomposition The question about yeast breaking down in the fermenter got me thinking about an old question I have about trub decomposition. I have searched high and low for good data on trub break down and I can't find it. Exactly what is taking place and over what time period. I think this is so key in regards to whether or not a secondary fermenter is necessary when fermenting an ale. Some sources will say the secondary method is better because trub breaks down but there is never any specifics. I want to find out if there is any decomposition over a two week period(past the flavor threshold.) It is my feeling and experience that there is none over this relatively short time period. This is purely based on taste tests. Olin Schultz Return to table of contents

Any ideas on whether it was > likely triggered by the yeast or hops? Any opinion on whether it > is likely a reaction to low hopped, filtered beer will pass? Allergies are funny things. They can seem to pop up overnight. Once one has a reaction, it takes less of an allergen to create the reaction the second time. Which is why your friend reacted to the Rolling Rock- which he probably could have drank before. It does sound like your friend is now allergic to hops. Have him stay away from all beer for a month, and then try to drink only low hopped beer in moderation. If he still has a reaction to the beer, then he may need to avoid hops forever, as awful as that sounds. Someone posted a couple of weeks ago about a friend who was having allergy problems with homebrew. If you brew, invite your allergic friend over, and have the phone nearby to call 911- &/or have a bee sting kit ready. Let your friend cautiously handle every ingredient you put into your beer, and see what they have an allergic reaction to. Smoosh some hops in your fingers and let your friend sniff then taste. When they begin to react, immediately remove them from the brewing area, wash their hands & yours, and call 911 if needed. If you finish the wort boil, let them try a sample of that (all of the hop oils should be released). If they have no allergic reactions during the process, and they still have an allergic reaction to your homebrew, they may be allergic to any esters that yeast strain produced, and as a homebrewer that is much harder to control. Another source of problems can be the cleansers and sanitizers inherent to homebrewing to prevent infection. Some people cannot cope with bleach, others are allergic to iodine. Rinse everything thoroughly. I am not a doctor. I'm just somebody with multiple chemical sensitivity and extreme allergies, and speaking from personal experience. I cannot use bleach, idophor, citric acid, or campden tablets (I also make wine). I accept the risk of infection as part of my brewing.

I use a program by the name of Labels Unlimited 2, but any kind of DTP will do very nicely. Other than that KennyEddy explains the procedure very well. I have not tried it, but I have heard that milk makes a very good label glue - just brush it on with a basting brush or a paint brush. Alan, thanks for the info, on the wonders of US electricity. If you have 220V in every house then why are the power points rated at 110V? It's annoying that I cannot buy electrical equipment from the US, nor bring things over. Brad Return to table of contents
Date: Wed, 07 Jan 1998 22:09:08 +1000 From: Brad McMahon <brad at sa.apana.org.au> Subject: They KillKenny! Gregg Soh wanted to Kill Kenny. Rather than watch South Park, I think we better hit our brewerys to work it out. Now, I can't get Kilkenny where I live, but I did look it up. Roger Protz in "The Ale Trail" (ISBN 1-85882-041-3), talks about Smithwick's of Killkenny's Draught. He describes it as having: "3.5 per cent alcohol with twenty-two units of bitterness. It has a creamy, malty, estery aroma with a hint of dark fruit in the mouth and bittersweet finish. An export version is four percent ..." (page 179) I also know it has a reddish colour to it. Now, I have had Caffrey's Draught, so I will assume it is similar in character. Irish breweries tend to use Northdown and Target hops alot, with Goldings and Challenger also used in smaller quantities. Given this, I used only Northdown and Target, as I feel that Fuggles/Goldings/Williamette may make the beer too English in character. Also draught beers are generally not very hoppy, so I have avoided those finishing hops, relying on some flavour from the bittering hops. Protz also tells us that Killkenny is served cold at 7degC/44degF and he had to wait for it to warm up to drinkable ale temperature! Given this cold temp for an ale, a lot of the aroma and flavour would be lost at this temperature. If Target and Northdown are not available try Northern Brewer, or/and Bullion. Now, you didn't say whether you are an all grain brewer or an extract brewer, so I flipped a coin and decided to work out an extract recipe. If you are an all grain brewer then it shouldn't be hard to convert. __MY GUESS__ So lets try this (I worked in metric but converted back to screwed up British engineering units so that American brewers don't have to think too hard. :-) I calculated this as a 19 litre (5 US Gallon batch)) 2kg (4.4lbs) Light Malt Syrup 500g (1lb) British Crystal Malt (60L) 0.5 oz Target (11% AA) (boil) 0.25 oz Northdown (8% AA) (boil) 0.25 oz Northdown (8% AA) (finishing) 1 tsp gypsum. Irish or English Ale yeast. This should have a SG of 1.038 or so, so 3.5 - 4% alcohol would be OK. Depending on the colour of your liquid extract the SRM should be around 15-20. The Bitterness I calculated using Tinseth's figures and got 25 IBU, Garetz gave me 20 IBU, so this is a good ball park figure. NB: I have NOT tried this recipe - it is pure conjecture on my part. I more than welcome comments from other brewers, and perhaps we can collectively work out a better recipe. Brad McMahon Return to table of contents
Date: Wed, 07 Jan 1998 06:10:13 -0600 From: "John Lifer, jr" <jliferjr at misnet.com> Subject: Re:food grade plastics On Tuesday Fred Johnson replied to the question of using plastics in brewing. I had responded the previous day to the original question and I must expand on this a little. Most colorants used in plastics today would be considered 'food safe' by most standards. There are not too many manufacturers using heavy metals such as cadmium in their colorants today. Having said that, there are a lot of reprocessors who will use any HDPE (high density polyethylene) in their HDPE and PP(polypropylene) in their PP products. In most cases these repros are colored. If the bucket or container is clear or natural white then you can be pretty sure that it is ok for food. Not completely sure, but close. If it is white, it may contain a UV stabilizer. This would be such as the bucket used to hold the drywall material. I would bet that it is NOT food safe. It may sit outside in the sun and the UV stabilizer was added to prevent degradation. I know that pickle bucket are green but they use the proper colorants. Be safe and use a container that a food product was shipped in or is made to hold food. I would hate to read that a HB'er died from poisoning. (remote but stranger things have happened). Ask about labeling 5g buckets to prevent drowning. John in Mississippi Return to table of contents
