---------------------------------------------------------------------- Date: Fri, 14 Mar 1997 16:12:22 -0500 From: Steve Alexander <stevea at clv.mcd.mot.com> Subject: Just Hops packaging ... I recently posted a note recommending 'Just Hops' (800-934-2739) as a Hops source because of their excellent selection and prices. I got one followup email, the author stating that he had gotten hops from Just Hops (under previous owner?) in a plain poly bag with a twist-tie closure !! I called Just Hops' owner, Pete Lujan, to discuss this. Pete tells me that they are using the same methods and sources as Mark Kellum, the previous Just Hops owner. The bags come from American Plastic, are listed as oxygen barrier and are vacuum sealed. Pete tells me that they have never operated differently since taking over Just Hops from Mark Kellum last year. I have personally ordered whole hops from Just Hops over the past several years, from Kellum and recently from Lujan, and have always gotten my hops in oxygen barrier vaccuum sealed bags. Same friendly service from Pete too. no affiliation, just a satisfied customer, Steve Alexander Return to table of contents

Date: Fri, 14 Mar 97 13:32 PST From: cburns at egusd.k12.ca.us (Charles Burns) Subject: re: Decocting Pale Ale Malt Steve analyzes my decoction disasters with Pale Ale Malt in HBD 2374: <big snip> If you are decocting pale ale malt, skip the protein rest and go straight from mash in to saccharification temps, then to mashout. <another big snip> So, mashin in at 140, no rest, pull the thick part of mash, raise to 158F in kettle over 15 - 20 minutes, then boil it for 15 minutes then dump it back into the rest mash? My guess is that in my original 20 minute rest at 140F, 90% of the starch was converted and all the enzymes leached out into the liquid mash. When I pulled 80% to the kettle and started fooling with it, regardless of temp control problems, all the sugar and all the enzymes remained in the rest mash. In the 20-40 minutes of screwing around with the decoction, all the starches and sugars left in the rest mash got converted/broken down to extremely simple sugars. So when the decoction was returned to the rest mash, it was too late to do anything. I could have tested for this with an iodine test but I have never taken the time to do that. With the process of mashing in at 140f and going straight to the decoction without a 20 minute rest, I'm still afraid that lots of enzymes would be left in the rest mash, but it sounds like very little conversion would be made until I got the decoction going. Sounds plausible, but difficult due to the very tight time constraints. Might as well just get some of that Belgian Pale Malt or Belgian Munich (or both) and have an easier time of it. More comments? Thanks Steve, I'm beginning to feel a little less stupid about this painful lesson. Charley Return to table of contents
Date: Fri, 14 Mar 1997 17:10:20 -0500 From: Tim Martin <TimM at southwest.cc.nc.us> Subject: Summary of decoction at mashout Hey Neighbors, My question was will it harm or improve my beer and allow me to mashout in a Gott cooler if I do a simple decoction at the end of the mash. Well....first I would like to thank! all who took their valuable time to respond to me. I generally like to thank people individually but I had enough responses that I thought I would do it here and include a summary. Second....boy I'm I glad I didn't try this first before I ran it by you all. Logic doesn't always dictate the best course to take in this hobby/obsession. All responses indicated "Do Not Do This" at the end of the mash because of the starch that will be released and no enzymes left to convert the starch. Many did indicate that I could drain the grains of the wort and then boil the wort and add back to the mash to reach mashout temp. One person did think this helped improve the flavor of his beer. Guess I still feel skeptical that this would contribute to any flavor enhancement. The only time I had a stuck sparge was my first all grain batch using my homemade EM in my Gott cooler. When I started to recirculate it stuck like snot on a doorknob. After that experience I now fill the cooler with sparge water before I begin to recirculate and I've never had a problem since. So.... I would consider draining my wort to boil and add back to the mash for mashout but I guess I would first have to add the sparge water and float my grains which tends to add more time and hassle to the process for all I receive. Well, thanks again for keeping me on course and out of the rocks. Tim Martin Cullowhee, NC Return to table of contents
Date: Fri, 14 Mar 97 17:50:35 UT From: "C&S Peterson" <CNS_PETERSON at msn.com> Subject: Decoction Troubles HBDers - C. Burns writes about his decoction troubles. CB, decoctions can be fun....really! Since I don't know all the particulars, let me just give you some possible leads on your head/body problems and that dishwater thing. My views are based solely on my singular experience; others in the collective may have better informed suggestions. - Decoctions are really designed for under-modified malt. This usually means lager (even US 2-row like Klages) or German malts (pils, lager, vienna, munich, etc). BUT, today, even these malts are pretty well modified. My suggestion (and others will differ here) is to limit or skip the 122 rest. I have had really good results in simply splitting the grist into their 1/3, 2/3 portions, running the 1/3 decoction mash from 130 for 15 minutes, 160 for 30 minutes, and to boil. When the decoction mash begins to boil, infuse the rest (e.g.: 2/3 grist portion) with hot water to bring it to 140 for 15 to 30 minutes, depending on how long you want to boil the decoction. Then combine the two mashes for the main rest at 158-162. The final decoction is the "thin" one to get to mash out. For, me this method has worked like a charm. I have used the traditional method which brings the whole mash through 122 for a long time, and have had tasty but thin, headless beers. Before you try this though, make sure you think it all through. Exactly how much hot water are you going to need and when. This is a PIA the first couple of times through, but once you get the hang of it I find it to be second nature. - For temperature control, I have found it is useless to even attempt to get a good temperature distribution unless you have at least 1Q of liquor per # of water. And here is one of the advantages of decoction. You can start with a fairly thin mash, and since you are bringing a part of it to a boil, you don't need a lot of infusion water (in fact with the method above, I usually have to add cold water or ice after combining the decoction and rest mashes). I don't pay attention to those that advocate thick mashes for fuller beers, better conversion, etc. They maybe right, but I think temperature control is more important, and whatever advantage there is in thicker mashes, I have found it self-defeating in that I cannot hit the right temps, I scorch the decoction, aerate the mash in over stirring, and generally have an unenjoyable decoction session. And I make some pretty malty beers starting with what would be considered a "thin" mash...... - For your dishwater taste, make sure you are checking the Ph BEFORE you get the grain above 160F. Use really good Ph strips (I get mine from Brewer's Resource; they cost about $15/100, but are well worth it), or a calabrated Ph meter. DON'T SCREW AROUND HERE. A high Ph on a decoction spells "slug bait" - -- you will leach out tannins and other nasty stuff that will give your beer one foul taste. As you can tell I had to learn the hard way on this one too (20 gallons down the drain last year........). So make sure that you measure a cool sample, or make a correction (I simply make sure the Ph is around 5 to 5.2 uncorrected), and don't oversparge. Its better to lose a little efficiency by undersparging than to oversparge and ruin a whole batch of beer. - As far a decoction for ales, I tried this on an old ale last year. It worked OK. But again, British malts are well modified, so a protein rest is really unnecessary. For my maltier ales, I like to simply perform the "thin" decoction. This is essentially the carmelization technique I think Noonan refers to in his Scotch Ale book (I could have the reference wrong here...). But it provides a little extra heat for mash out, giving me more room in my mash tun for grain. Hope this helps, Chas Peterson Laytonsville, Md Return to table of contents
Date: Fri, 14 Mar 1997 09:02:42 -0600 From: Rick Olivo <ahspress at win.bright.net> Subject: Brew Tunes In response to the thread initiated by Karl Lutzen about Brew Music. I invite folks to listern to the rollicking ditty by Tom T. Hall, "I Love Beer" "Whisky's too rough Champagne costs too much and Vodka puts my mouth in gear. This little refrain should help to explain as a matter of fact I like beer!" You get the idea... It's a song best sang after consuming a few bottles of homebrew. As a matter of fact, (so to speak) the song (Available in the collection "The best of Tom T. Hall") is just one of many by Tom I enjoy while whipping up another batch of "Old Smiling Jackass Cetic Strong Ale." I also enjoy Hank Thompson's and the Brazo Creek Boys collection "And a six-pack to go" a real classic of 50's country and rockabilly with a beer-drinking theme. I also would add my "me too" to Skotrat's (Scott Abene's) spirited defense of Scottish, Celtic, Gaelic etc. music as being fitted for brewing. This kind of music adds deep emotion to the brewing process, a factor that is every bit as important as high quality malt, fresh, pungent hops, pure brewing water or lively yeast. I mean, what is going to give you better beer, a single, kilted master piper playing the sweet, comforting strains of "Amazing Grace" or Marilyn Manson playing "Antichrist Superstar?" I rest my case.

Just wondering if anyone had tried using one of those paint stirrer attachments for a hand drill to aerate the wort. Others have said that it is the mixing action that provides most of the oxygen uptake by the wort fluid. Seems to me that this is a tool which is specifically designed to move thick liquids around with a minimum of splashing ... and can be had cheap at any hardware store. Just a suggestion, I guess.

Date: Sat, 15 Mar 1997 07:41:56 -0800 From: Kent Michaelsen <kentmich at tiac.net> Subject: Re: Pubs in UK Rick- While not English, I do get to London fairly often on business. Unfortunately I can't find Harlow in my CAMRA guide. Now this doesn't mean it is without merit, nor that it doesn't have any good pubs in it. You'll merely have to try them all, until you find the right one;) I believe it is right to the north of London? As for London, there are so many I'd need to know roughly what area of the City you'll be staying in. Email me if you wish and I'll be glad to look some up for you. The London area specializes in and bitters, and like Germany it is difficult to find many regional favorites outside their home area - so forget about "real" porters, stouts, etc. other than normal keg types. Two favorite "live" cask-conditioned bitters that are easy to find in London are "Fuller's London Pride" and "Adnams". Both are former CAMRA Beers of the Year, and represent the style well. If you like IPAs, you might have to search a bit - I've tried Green King and found it thin and watery. IPA seems best represented in bottles. Again, the CAMRA Good Beer Guide is available in any bookstore in England, and I highly recommend you get it. It describes not only the best pubs (based on quality and variety of "real" beers) but the hundreds of beers to be found as well. Have fun.

Date: Sat, 15 Mar 1997 11:49:10 -0500 (EST) From: AllDey at aol.com Subject: Throttling back the 'ole pump I recently acquired a 1/25 hp Teel model 1P677A magnetically coupled pump after reviewing HBD back issues and visiting extremely some helpful RIMS sites. I intend to use it for re-circulating mash and transferring to the kettle. Advice gleaned from various sources warn against restricting inflow; instead, folks suggest using a valve on the outlet side to reduce flow to a more desirable 1/2 gal per minute rate. Will this hurt the pump? Eventually? (It seems like an awfull lot of pressure builds up when I have a valve and run water through, but pump still sounds ok). Can a voltage controller be used with this particular pump? Private posts are fine since I know this topic has been beat to death...but I still can't seem to locate the specific answers I need.

I use my work account for HBD and my home account for Usenet, mostly. I rarely (maybe never) receive SPAM on my work account, but it's a regular feature on the home account. Do any of you also post to Usenet? That'd be my first suspicion. I'd also question my ISP to see what their revenue-generating policies are. Many of us have taken to modifying out "reply to" fields and making a note of the modifications in our sigs to foil spammers. It's a PITA for legitimate mail, but it is effective. There is a SPAM FAQ somewhere on the Web, but I don't have the URL here at home. If this crap bothers you, be sure to complain (politely) to the ISP. Many services have an abuse address, i.e. abuse at ISP.com you can complain to. AOL does, FWIW. By law I believe, every ISP must have an webmaster at ISP.com you can also complain to. Dave wrote: " All of them require a "remove" response since they all = promise (threaten) more e mail to follow. " Beware of this too! The FAQ says that this is often a ploy to generate, you guessed it, another advertizing mailing list. Always complain to the service provider first. If you _do_ happen to get brewing-related SPAM, I'd look to the AHA since I have a very strong suspicion that that's the source of my snail-mail junk mail ;-) Randy in Modesto Return to table of contents
Date: Sat, 15 Mar 1997 19:44:08 -0600 From: Kristin Miller/Carl Helrich <knc at comsource.net> Subject: toxic beers and Papazian's books... I have only been reading the HBD since January, so I apologize if my question has been covered before--I'll search the archives dutifully then. As a new brewer, I as others have relied on TNCJOHB as my ultimate reference guide. My ever-supportive wife gave me the go-ahead today to purchase Papazian's _Homebrewer's Companion_. I say that she is supportive, because I have not had what one would call an out-and-out successful batch (out of eight). Most have been drinkable, and out of pride that's what I've done. She thinks it incredible that I still am brewing. For me it's a challenge not to let the little yeasties kick my butt. So, with the new book, I turned to the Troubleshooting guide of course, trying to determine what *exactly* the cause for my cidery/sour/fruity(apple) flavors is. On page 409 at the bottom he notes that "some of these substances are toxic and should not be tasted." Yet I remember in TNCJOHB that he wrote (on page 363), "Because of beer's acidity and alcohol content, there are no known pathogen's that can survive in beer;therefore, you aren't going to die." This seems to be a fairly hazey issue (unlike my homebrew). I really want to drink what I have bottled at this point, but now I'm hesitant to do so. I have drunk the previous batches with no ill effects so far. Is it killing me slowly? In any case, I'd love to hear some responses from those more experienced than I. And if some one can help me with my off-flavors--I use all malt-extracts, aerate cool wort, ferment ales at 66 F in closed glass carboys, and my meads have all tasted great--I would appreciate it.

I live in Florida and I'm on my 3rd year of growing Cascades. Last year I had about 2oz of flowers. The previous year I had some flowers, but not much. I grow the hops in gallon plastic pots that have holes in the bottom. The roots grow through the holes. After the first year I cut the roots at the bottom of the pots and moved them. In hopes that the roots in the ground would grow. Nothing happened. Now I'm hearing that right now would be the best time to cut the roots. But my plants are about 4 ft high with right now. Can I cut the root at the bottom of the pot again to get new plants? Will it hurt my current growth? BTW: I can only grow hops in Florida by planting them on the South side of my tool shed. That way they only get the morning sun. I tried full sun, but it kills them. - ------------------------------------------------------------------ Chris Strickland - Approved Discount Vendor for SecureTax Email: cstrick at iu.net New Horizons Software - http://www.sitesurfer.com/newhoriz [Programming/UNIX/WEB Services,Central Fl Jobs, Entertainment, Vacation, College Football] Return to table of contents
Date: Sun, 16 Mar 1997 07:42:49 -0800 From: Kent Michaelsen <kentmich at tiac.net> Subject: Re: Live Beer I share your love of "live beer", based on many hours wandering London, CAMRA guide in hand, while supposedly on business. There's a good diagram and description of beer engines in the Classic Beer Style Series "Pale Ale" (Brewers Publications, Boulder CO). Since you're interested in real ales, it's a good book to get from your supplier. Describes the whole genre from brewing history through how they pump it up from the basement. Pictures and diagrams etc. Basically it's just a hand powered pump with a piston and cylinder to pump the beer out of the cask. The big difference between dispensing "real ale" and "keg beer" is that a cask conditioned pale ale in the British style doesn't have enough CO2 (only about 1 volume vs. the normal 2 or 2.5) to force itself out of the cask the way a keg beer might, let alone get itself upstairs. And to put enough CO2 pressure on it to force it up from the cellar would gradually force-carbonate the beer, causing it to be over-carbonated for the style. The beer engine pumps the beer itself, and filtered air replaces it in the cask. Thus the beer must be consumed within a few days before it goes bad. The obvious solution would be to pipe CO2 under zero pressure in to replace the beer instead of using air, but CAMRA refuses to list any pub which does this, and apparently very few do. Not the proper way, you know, and that's what real ale is all about. Additionally, there is often a "sparkler" or restrictor nozzle built into the pump. While the ale shouldn't have enough CO2 to harm the taste, a nice head is preferred (especially in the north, they tell me). So the sparkler causes enough turbulence to take what CO2 there is and cause a head. Basically what you want is an almost flat, slightly cool beer but with a head. Now that I think about it, I guess I know why my Bud drinking friends think I'm crazy! Some homebrewers simulate the sparkler by shooting air (70% nitrogen after all) into a glass of beer with a syringe to generate a head. Naturally, artifically injecting either CO2 or nitrogen into beer is cause for expulsion from CAMRA and death by one thousand Bud Lites. Wooden casks are generally replaced with metal now. As for the concept of brewpubs serving real ale, they're going like gangbusters here in the States.

A few first time goofs, like not enough sparge water, trouble getting correct temperatures, and too much evaporation in the boil, but nothing major. All in all, the pale ale is better than my expectations. A question: How does one measure the efficiency of the mash and sparge? I have seen the magic numbers one shoots for, but just how do I know how well I am doing? Any replies gratefully accepted. Jim Hust Lincoln, NE Return to table of contents
Date: Sun, 16 Mar 1997 11:57:43 -0500 From: mel at genrad.com (Mark E. Lubben) Subject: split/decoction The recent posts with decoction questions prompted me to post my split/decoction method. I get the decoction character AND great head with modern European pilsner or American two row malt. When I forget the Irish Moss (IFTIM) chill haze hasn't been a problem yet. I credit a suggestion Dr Fix made in his book "Vienna" to avoid extended (protein) rests at 45C-55C (50C=122F) if you want good head proteins. By the time you finish a normal decoction, the main mash has been in that range for 90 minutes. When I first tried it I goofed around for two hours! I found that just boiling the sweet liquid for mashout didn't taste the same. I developed a variation which gives me more flexibility and better control. The heating is boiling already converted grains with minimal time concerns. You Will need to measure water volumes and trust your thermometer more. I assume you know what your water does/doesn't need for a normal mash. If your jet burner smokes when adjusted low, use the kitchen for the decoction. - --- Split/Decoction for 10lb / 5 gallon batch (fits a 5 gallon Gott) --- Double all weights and volumes for 10 gallons Grind and divide your grain (assumed about 60F): 3lb grain - decoction mash (normal % of light crystals here) 7lb grain - main mash (put any Special B or roast grains in here) Beware: grain works out to 1/3 quart per pound added to the water volume. If your cooler isn't over half full with 10lb grain and 3.5 gallons you will probably loose enough heat that you may need to add some boiling water during saccharification. Either that, or double all the quantities to 10 gallons and your temperature will drop about half as much, plus more beer. :^) I wouldn't try these mash rests in an uninsulated Zapap bucket. Preheat a Gott or SMALL rectangular cooler with hot tap water while heating your brewing water. Empty it and put 2.5 gallons of 155F water into the cooler. I assume you will loose about 8 degrees in bringing the cooler up to final temp and other loses over the next 90 minutes. If you have doubts, try it ahead of time and adjust your temp up if needed on brew day. It is easier to stir vigorously with the lid off, or add a handful of ice cubes than it is to raise insulated cooler temperatures. Heat 1 gallon of water to 165F in a big kitchen pot of at least 2 gallons. Stir in 3lb of grain, you should hit 150F-155F. If too far off, adjust the temperature. Now cover, and wrap towels around the pot (off the burner), or put it in a preheated (150F) oven with the heat off for 30 minutes. Put the pot back on the burner with medium heat, stirring occasionally. If you have only one brewing thermometer, put it in the mash tun eventually. Within 15-30 minutes you should get the decoction boiling. Turn off the heat. Check the water in the cooler is near 148F, and stir in the grain for the main mash and cover it (130F-135F). Now turn the heat back up on the decoction and boil for 30 minutes. You can add a quart of water midway for evaporation. Add the decoction to the main mash and stir. I find I get better mixing of the grains if I mix with a spatula making a vertical J pushing down and then toward an edge. The grain from the main mash swirls up the mash tun into the hot liquid on top. Circular stirring leaves two spinning layers unmixed. Check the temperature is a little above 150F and close the lid. If it is above 155F it usually means I haven't mixed well, so mix some more with the lid open. If it stays high, add a handful of ice. Nervous types can hold 1/3 of the decoction until sure the temperature won't be too high. >From here on it is mostly like a step mash, although you will discover about half of your hot break on top of the grain when your lauter tun drains. I let the mash rest for about an hour. My iodine tests (if done) always pass even earlier with this mash schedule but I let it go to reduce sweetness. The big advantage of this approach is that by striking the main mash separately, my main mash has a 30 minute 132F rest instead of a 90 minute 122F rest. The decoction starts out simple like a small infusion mash. Also if I get delayed early with the decoction mash or boiling, my main mash isn't "ticking away" burning off the heading proteins. The main disadvantage for pale ale malt is that all the amylase for the decoction is being boiled, but it is after a 150F rest which can be extended until the starch available before boiling is converted. With a 132F rest the main batch of amylase is rarein' to go. If you want a compromise to cut some time, the main mash could be started after 30 minutes of rest on the decoction. Then heat the decoction to boiling in under 15 minutes and boil for the remainder of the 30 minute 132F rest of the main mash. For those who mash in a keg, this split technique reduces the main mash time and hits a higher rest. By adding a lid and blanket/cover with a 10 gallon batch it might be stable enough for the 30 minutes without heat to produce good head protein levels. I suppose the main grains could even be added infusion style after the decoction is mixed into the main ~140F+ water. One might even be able to do it in one of those triple keg rigs using the mash tun for the decoction, then adding the main grain and water after tempering the decoction with part of the main mash water from the liquor tank. (Don't blame me if this makes a scorched mess. I haven't tried it!) Happy split/decocting Mark Lubben (Sorry for the length - I tried to include the newbies) Return to table of contents

Date: Sun, 16 Mar 1997 19:47:47 -0500 From: "Frederick L. Pauly" <flp2m at avery.med.virginia.edu> Subject: Quest:How to keep keg carbinated? I want to keep my keg at 2.4 vols to keep the proper carbination at 48F but I need it down to 5 or 6 for delivery. So I get it carbinated properly and then have to reduce the pressure for delivery and am to lazy at the end of the day to make sure the keg is back at 15 psi to keep it at the right level of carbination. I'm trying to think of some way to make sure the keg stays at the proper pressure level with out having to remember to put it there. I have an idea I'm going to run by you but I'm sure someone out there has already developed an elegant solution that they would be more than happy to share with me. Since I have one CO2 tank that I use for various purposes in my homebrew operation my plan was to have a hose through the side of the beer fridge for the CO2 hooked to the kegs on the inside and on the outside to some valve that would allow me to disconnect the tank when I needed it for something else. Then, keeping the beer at 15 psi and using 4-5 feet of beer delivery hose to drop the pressure to resonable tap pressure. What do you think? Rick Pauly Charlottesville,VA Return to table of contents
Date: Sun, 16 Mar 1997 22:00:13 -0500 (EST) From: nkanous at tir.com (nkanous) Subject: Making BIG Starters Greetings collective! Large starters are beneficial to complete and optimal fermentation. In creating those large starters, what about technique? Is it necessary to progressively increase the starter (Daniels recommends 1.2 gallons optimal for 5 gal wort) to a large volume, or can you repeatedly decant off the "spent" starter and add fresh wort to a total of 1.2 gallons, while keeping the actual starter size much smaller and manageable (i.e. less extract in my brew)? Hope this makes sense. Thanks. Nathan3 Return to table of contents
Date: Sun, 16 Mar 1997 23:56:00 -0500 (EST) From: Alex Santic <alex at salley.com> Subject: Stuck fermentation update The outcome of the dysfunctional porter fermentation, along with some comments on public and private responses. One person suggested that re-culturing some yeast from the first problematic fermentation was a bad idea. I understand the sentiment and it did cross my mind, but instinct told me that the yeast was fine. As I mentioned, I made a connection between my observations and the situation described in BT 4.5, starting on page 14. I don't think that writer was having yeast problems either, but rather it is some aspect of the wort composition that is causing difficulty without necessarily affecting the viability of the yeast. My secondary now has a nice layer of clean yeast that I intend to pitch into a dry stout wort, and we will see how it works. It was suggested to me in a private repsonse that the Irish Ale strain is pH sensitive and has a tendency to quit early if the pH drops too low. I think that might well be on the right track. It may not even be the yeast strain per se, but just that this yeast is popular in dark ales with a lot of roasted grains. In future brews I intend to keep calcium out of the mash entirely apart from what might be in the water. I wonder if anybody has a WAG as to why, at a certain pH, foam production would stop while the yeast is actively fermenting, and why there would be a buildup of CO2 bringing things to a halt. Another person suggested that the fermentation was actually complete at 1.020. Of course I had considered the possibility, but not for more than a few seconds. It wasn't plausible considering an all-grain wort mashed at 152F with the grain bill I described. No way it could have been finished at 60% apparent attenuation. What actually happened is that the SG didn't budge until I started the swirling routine that I described. Several times a day, over the course of several days, I was able to generate an impressive outgassing of CO2 by swirling the carboy. This amount of dissolved CO2 could not plausibly be left over from primary fermentation. Activity seemed to continue as long as I caused the gas to escape. This weekend, I checked the SG again and it had fallen to 1.016, a much more plausible FG considering we started at 1.050. I'm now crash-chilling the ale to drop out all the yeast and I intend to prime relatively lightly for bottling. If I were pasteurizing this beer, I'd have to name it Shake 'n' Bake porter. :) Alex Santic New York City Return to table of contents
