My girlfriend and I were in Vancouver over the summer and were looking for a good brewpub to stop in for dinner and some good house brew. We passed Steamworks and considered going in but due to their proximity to Gastown -- one of the main tourist drags in Vancouver -- as well as the giant garish sign out front, we nearly passed them by. We assumed that they were just another bland, watered-down, trendy brewpub. But then it started to rain so we said "screw it" and ducked in. I'm glad we did because we had some of the best beer (and food) that we had on our vacation (which also took us through Washington and Oregon). We drank their Sour Cherry Belgian Ale, Wit, Porter, and IPA, all of which were excellent (although their Wit was a little unbalanced). We also had a great dinner. My girlfriend was served the largest piece of Ahi Tuna that I have ever seen. I'm glad we took a chance on Steamworks. -- Matt Return to table of contents
Date: Mon, 4 Mar 2002 22:48:13 -0800 (PST) From: John Schnupp <johnschnupp at yahoo.com> Subject: Maple sap and syrup Cool something I know a little bit about, being from the #1 maple syrup producer in the United States (48.9% production from New England and 26% nationally). The production in 2001 was 275,000 gallons. At 36 gallons sap (average) to make one gallon of syrup that is a lot (9,900,000 gallons) of sap. One product that is produced is called sweet water. It is carbonated maple sap. I used to pick this up in a local general store/farm stand but have not seen it in a while. If you have access to maple sap and do kegging, you have everything you need. Carbonate to about 40-50 psi. Makes a nice refreshing drink when served cold. ===== John Schnupp, N3CNL ???

Date: 5 Mar 2002 04:49:34 -0800 From: Jonathan Royce <jtroyce at directvinternet.com> Subject: RE: arrested fermentation "I was thinking of pulling some brew out of my next batch when it hits about 0.5% alcohol. Then running it through a wort chiller to bring it to near freezing temps. "Would this kill off the yeast (ale yeast)? I doubt very much that near freezing temperatures would kill yeast--it would more likely just go dormant. Meaning that, if it were to warm up again, I suspect it would become active. "Also, could I then use a real fine filter to filter out most of the yeast?" Absolutely. Many commercial breweries (and vineyards) use fine filters (0.45 - 10 micron) to remove yeast and other non-desireables prior to bottling. These filters vary from cellulose pads or polypropylene wraps (depth filters) to pleated polymer membranes (surface filters). The only drawback for the homebrewer is that these filters tend to be expensive.

Date: Tue, 05 Mar 2002 07:34:11 -0800 From: Dean Fikar <dfikar at swbell.net> Subject: Re: 2206 - weird yeast behavior Alan Meeker sez: "I just had a strange experience with Wyeast's 2206 and am wondering if anyone else has seen anything similar." Alan, 2206 was my favorite lager strain until I had problems with two batches in the last year. The first was a big doppelbock which stuck at 1.040 (OG 1.098) and the second, months later, was a Dunkel which stuck at about 1.026-1.028 (OG 1.059). The bock was pitched with slurry which was refrigerated for a few weeks and then restarted with 2L of canned wort. The dunkel was pitched with a 2L starter from a new smack pack. I eventually racked the dopplebock onto the Ayinger yeast cake of a recently brewed CAP which took the SG down to about 1.025. With the dunkel I pitched the slurry from a 2L starter (Ayinger from a slant) and got the SG down to 1.022 which, though still high, was about where it should have been since I mashed at 158F. I later got some feedback from Louis Bonham who has heard anecdotal reports of similar behavior from the 2206 strain. Perhaps he can comment further if he has any insight into this puzzling yeast behavior. I think I'm going to switch to Wyeast 2308 which IMHO gets a bad rap as a finicky yeast. I've never had any problem with it myself. I'd be interested in suggestions for any other 2206 replacement that folks may have. BTW, though I love the Ayinger strain it doesn't seem to accent maltiness as much as 2206 does in bocks, fests, and the like. Makes a great CAP though (thanks Jeff!). Dean Fikar Ft.

I have a large plastic sink that I wash my fermenter and carboys in, but take my sanke outside. I'm now toying with the idea of building a "cradle" that my carboys and keg will fit into. Something with a V shape on four legs to keep the round object in place. The hind legs taller to create an angle for easy drainage. The whole thing could sit tall enough to drain right into the sink. I could set it right next to the sink, scrub, rinse with a hose, etc. I could probably even get a small garden sprayer filled with iodophor to reach in the carboys and spray the insides for sanitation. Let it set a few minutes and rinse. Sound doable?>> Richard, I can't quite recall where I found this link (http://www.cros.net/cruiser/carboy/carboy.html) to Nate's Carboy Safety Carrier Page, but this seems like a very elegant solution to a vexing problem. How to handle those glass buggers while slippery and soapy. This little doodad could be made from almost any type of lumber material hanging around, and with a little woodworking (or a buddy who knows how - paid with tasty homebrew) could make this in short order. I have even invested in a dado head for my old table saw to knock a couple out. I will post if they are cool as they look. Your proposal of a tilted rack would still leave liquid material in the carboy after cleaning, and then what do you do with the other ones that require attention? Nate's carrier can be stacked and inverted to allow for complete draining, air drying, and storage to keep clean (dust, debris, creepy crawlies, etc.). I like it.

Date: Tue, 5 Mar 2002 07:50:44 -0800 From: Demonick <demonick at zgi.com> Subject: RE: The mash tun dilemma I'd like to expand on what Bill Tobler <wctobler at sbcglobal.net> pointed out. >With the extra space, you can step up with hot water, and do a >mash out. You can't do that in a 5 gallon cooler. In a 10 gallon cooler you can do a step mash, where with a 5 gallon cooler you very quickly run out of room. I like to do a mash out in my 10 gallon Gott. A typical 5 gallon batch mash runs 4+ gallons with 10 lbs of grain and 1.25 quarts water/lb. 2 gallons of near boiling water bring the volume to over 6 gallons. With a 5 gallon cooler you'd have a gallon on the floor. Also, even without doing a mashout, during the sparge with a 5 gallon cooler and a 5 gallon batch you have to watch the sparge water inlet VERY carefully so as not to overflow the cooler. With a 10 gallon, you can just let it rip. My suggestion is to get both a 10 gallon and a 5 gallon. Set up the 10 gallon as a mash/lauter tun, and use the 5 gallon as a sparge water reservoir. If the kettle sits on the floor, the mash tun on a table, and the sparge reservoir on a box on the table, you have a little temporary, 3-tiered system that make life much easier.

FWIW, I tend to agree with Nathan's basic observation here, to wit, the great (to me anyway) difference in flavor between "draught" widget-canned Guinness and the much different bottled stuff... Though I've never experienced a "tang" (at least what *I* perceive/describe a tang to be) in either bottled or canned Guinness, I suspect, like others, including Mr. & Mrs. Babcock, that much is due to a certain hop characteristic(s) AND (this has not been mentioned yet) the carbonation factor... My first Guinness was bottled Guinness, and it remains my favorite (not ever having had the pleasure of sampling from a tap in Ireland...!). Something about the bubbles... The canned stuff is just too smoothed out for me; I like the "snap" of the bottled version...that is, the hop _and_ carbonation snap... Perhaps others can comment on how the C02 affects perceived taste...? At any rate, imagine, if you will, a weizen bier vom fass without that lovely effervesence... It would surely *taste* much different...n'cest-ce pas?

Probably so, but if you had a filter fine enough to guarantee that you got all the yeast, you would also end up filtering protein and other compounds as well. ....SNIP... >(PS: I have looked at vacuuming off the alcohol, but I like aromatic >brews.) Per previous discussions, this is a form of distillation, and frown'd upon by BB. Why not just brew a low alcohol beer. I'm down to about 2%abv with one of my brews called SNAL. It is a really tasty brew. You could experiment and prbably get to 1% or maybe less and still have a nice beer. The trick is in the use of specialty malts for flavor and body. My recipe calls for: Grain/Extract/Sugar 0.19 lbs. Special B Malt Belgian 1.030 120 2.50 lbs. Pilsener Belgium 1.037 2 1.00 lbs. Munich Malt Belgium 1.038 8 1.00 lbs.

Date: Tue, 05 Mar 2002 11:35:59 -0500 From: Marc Sedam <marc_sedam at unc.edu> Subject: drilling the Sankorny I posted something last week about what to do regarding finishing welds on my newly-welded Sankorny keg. I have a Dremel (high-speed rotary tool) and went to Home Despot, Lowes, and finally Sears to look for bits that would do the job. I tried cut-off wheels, heavy-duty cut off wheels, aluminum oxide grinding stones, SS brushes, and none of it worked. Until I learned the magic of two little words... TUNGSTEN CARBIDE. That stuff is pure magic. The bit ate through stainless like a drill press through wood. I was able to smooth out the stainless "lip" left during the welding. Once I got down to the place where the Sankey met the welded corny keg, very gentle pressure with the side of the bit made for one relatively smooth surface. Finished it off with the aluminum oxide grinding stone and it's pretty clean and smooth. I plan to use the dremel "polishing compound" to finish the welds followed by a gentle brushing with 180 grit paper and bathing all the welds in nitric acid to dissolve any iron and prevent rust. Of course doing all of this through the top hole of the corny lid is much harder than you'd think. Will take 3-4 hours to make the smooth surfaces. Thanks to all the HBDers who've made suggestions and helped with how to finish the welds to make them approach sanitary-grade. And yes, I also bought a pressure gauge from William's Brewing (NAYYY) so I can sterilize through steam pressure. I know some have cautioned against this use, but since I plan to use it as a serving tank on occasion it needs to be able to handle AT LEAST 20psi. If it can't then I've just created a very big, very expensive fermenter. Lastly, if the entire keg CAN be pressurized but there's the occasional nook or cranny in the weld, will the pressure be able to kill all the buggers? I can't believe I just asked that, but it's been a while since I used the autoclave--I seem to recall all surfaces had to be smooth and clean to be effectively sterilized.

Actually, this is a traditional brewing practice called sparging the hops. Normally it's done with hot sparge water. I've done it in the past myself, ans still do occasionally if I need to dilute my final volume. However, since I use an immersion chiller, I use cool water now. Dave Line wrote of it in his seminal (1974) "Big Book of Brewing," from which I learned to brew all grain more than 20 years ago. He wrote (p. 160) "Hops can absorb and retain a considerable amount of extract which must be retrieved to maintain efficiency and economy. Hop sparge with kettles of boiling water at the rate of approximately 1 pint per gallon of beer. Some of the protein matter will bound to be washed through by this action."

Date: Tue, 5 Mar 2002 09:27:06 -0800 From: "Hedglin, Nils A" <nils.a.hedglin at intel.com> Subject: Carbinator Cap problem Hi all, I finally tried the idea of carbonating my flat beer using CO2 & a Carbonator Cap. At first it seemed to work well, until I started shaking it & it sprayed me in my face. For some reason, the valve of the cap wasn't sealing, so the beer was foaming out of the top. Just minutes before, I had done a test to make sure I had the bottle had the right threading, & shot CO2 into the bottle when it was empty. I've also used it to carbonate home made root beer & cider too & it worked fine then. I didn't hear any gas escaping at that time. Once I put beer in it, I made sure to squeeze all the air out of the bottle before applying the CO2. Has anyone else seen this type of problem? Thanks, Nils Sacramento, CA Return to table of contents
Date: Tue, 05 Mar 2002 14:25:30 -0600 From: Paddock Wood Customer Service <experts at paddockwood.com> Subject: Harsh Flavour / Plastic Buckets w/ spigots Greg had posted about a nasty flavour in his beer, and later revealed that he had switched to plastic buckets from glass, and didn't rinse the Iodophor off. Iodophor must be carefully measured to be used as a no-rinse sanitizer, but I suspect that those spigots may be the problem, not the sanitizer. But I would recommend StarSan over Iodophor, as a no-rinse flavorless sanitizer (brewshop owner, yadda yadda yadda). Some spigots simply cannot be properly sanitized, and are only intended for the briefest of use in a bottling bucket. If used in a fermentor, eventually wort and hop bits can and will find their way into the inner workings of the spigot, and the spigot cannot be properly cleaned without a lot of hassle. Spigots that allow you to straighten or turn the spout (not merely the handle) to adjust the orientation after tightening the nut, have a tube-in-tube barrel that will allow wort to collect between the inner tube and outer barrel. It will not always be visible. The spigots can be snapped apart with some difficulty. Then you can clean them, but repeated dismantling will eventually lead to a leaky spigot. Spigots that are solid- one piece, except for the nut and the spout can sometimes be cleaned well enough to use for fermentation. I have seen "fast flow" spigots like these, but the tube-in-tube style are more common. We had experimented with providing fresh wort in ready to ferment buckets w/spigots, but the spigots became a source of infection. It didn't show up right away, nor did all the buckets get it. We ended up with a smokey sour lactobacillus infection, but there were no tell-tale rings or other obvious signs, other than an increasingly unpleasant taste. If Greg's troubles are indeed from the spigot, it may be an infection. Not all infections leave a ring, or produce cloudy beer. Buckets can be great, if they are replaced regularly, and not scrubbed with abrasives, but I would suggest using a bucket sans spigot. cheers, Stephen Ross -- "Vitae sine cerevisiis sugant."

Date: Tue, 05 Mar 2002 15:01:02 -0600 From: Paddock Wood Customer Service <experts at paddockwood.com> Subject: DCL Yeast - dry lager S-189 etc Paul asks: "What's the consensus on S23 vs. S189 with regards to flavor and performance? Is S23 truly fruity? I've seen S23 carried at a few homebrew stores, but does anybody carry S189? Perhaps its not a normally stocked item, being as its smallest available size is a 500g pack but could be special-ordered..." We normally stock vacuum packed 20 gm units of S-189 , $6.25 Canadian, so what's that, 50 cents USD? ;) It can go in an envelope to the USA without large shipping costs. We also sell the 500gm bricks. Our website isn't up to date, but we carry most of DCL yeast, most of the time. We were just as puzzled by the 'estery' and 'fruity' description, and also concluded that it must have been some Marketing rep who didn't know. Or maybe DCL covering their butts, but I find S-189 to be a fairly neutral yeast, good flocc, and a good choice if you do not aerate your wort, or if you wish to have some emergency lager yeast kicking around for a no-go starter or yeast. It's an extremely popular strain in Europe, and as noted on the HBD, it can tolerate abuse. I wouldn't suggest it if you knew that the temp was going to be high, Wyeast 2112 is better for that, but S-189 is a good choice for homebrewers who may have difficulty with temperature control. cheers, Stephen Ross -- "Vitae sine cerevisiis sugant."

According to what I have read, it seems that for the enzymatic processes to benefit from the gypsum/pH it would be right to set up the water and then mash. Any input?

I found a report on the web that gave an equation for calculating Cp of "barley" based on moisture content. Using a maximum of 5% moisture content from a maltster's web site, I came up with approx 1.18 KJ/(Kg)(degK). For those of you in the know, is that about right? Thanks in advance.

Date: Tue, 05 Mar 2002 20:11:49 -0700 From: Dave Larsen <HunahpuMonkey at comcast.net> Subject: Mash Panic Here is a little story. The other day was brew day -- my third all-grain batch. The first two went very well. I was pretty cocky going into the the third. I had this all-grain thing down pat. The new thing this brew day was a brand new thermometer. This was a new Pyrex digital thermometer. In previous batches, I had used an old deep fry thermometer, with a dial that had marks for every ten degrees, which made it hard to get exact temperatures. I had carefully checked the new thermometer with boiling and freezing water. It was off by 3F degrees exactly-- three degrees too low in fact. I knew this going in. This time, my temps were going to be exact. One of the problems I has always had in previous batches was getting my strike temp right. My mash in temperature always came out too low. This time, I decided to heat my mash water a full 180F degrees. So using my new thermometer, I heated my mash water to 183F degrees. Adjusting for the thermometer that was 180F degrees. Right?. I mixed it with my grain and -- presto -- according to my new thermometer it was 158F degrees. Adjust that by 3 degrees and it is 155F degrees. Perfect. Right? I put the lid on my gott cooler and waited for fifteen minutes. I decided that it was time to check on my perfect mash. Hmmmm. It had only dropped by one degree. This was going great. It was then, like a ray of light, I realized that I had adjusted the temp in the wrong direction! My mash had been 6 degrees to far into alpha amylase all along. ARGH! I quickly added some cold water and checked it. Still too high. Panic. More water. Mash now all watery. Mash tun too full. Out of room. Must remove some mash to add more cold water. GRRRRRRRR. Panic. Add more cold water. Finally, I stuck my brand new thermometer into the mash. It read 152F degrees. Thank God. No wait, 156F degrees. No wait, 160F degrees. I keep moving the thermometer to different places in the mash. 172F degrees. This sucks. Panic. Is too late? Have my enzymes all been killed off. Why does the mash vary so much from place to place? My wife yells out from the other room, "WHAT IS GOING ON?! You keep swearing like a truck driver." The temperature was now 186F degrees. Wait a second, that's higher than my mash water was going in. Something's wrong here. I pulled the thermometer out and plunged it into some boiling water. It read 236F degrees. The culprit was unveiled. Bad thermometer. Bad! That is my story. The batch is in the fermenter now. According to the iodine test, all the starches converted into something -- into what I don't know. Isn't homebrewing fun? Dave Larsen Return to table of contents
