---------------------------------------------------------------------- Date: Mon, 5 Mar 2001 03:19:27 -0500 From: "Stephen Alexander" <steve-alexander at worldnet.att.net> Subject: re: CC fermenters ... I apparently did stir up a conversation re cylindro-conical fermenters. Steve Claussen writes ... >As far as cleaning the exposed valve, I >agree that it must be done - but any method of harvesting will involve >cleaning. Ant Hayes adds his method of cleaning ports, and Richard Seiben on deficiencies of ball valves. BTW the vendor G.Fix mentioned sells a 12.2gal CC for about $400, and butterfly valves for another $100 ea. I think Ant missed my concern. If you don't clean the CC ports well *after* withdrawing trub you have a lovely environment on the blind port for infection - you will be flowing your harvested yeast past a dirty port. (Re)pitching lots of 'slightly' infected yeast isn't a solution. SteveC continues ... >Before I had a CC, harvesting was such a PITA that I only did >it a few times a year ?!!? Re-fluxing fresh wort over a clean secondary cake couldn't be easier. More often when I keg I store slurry in 2qt canning jars - sterile water washing before repitching if necessary. Why is it so much more difficult to pour from an emptied carboy to a jar than pour from a valve outlet to a jar ? >Now, I ALWAYS harvest, and the entire A hundred yeasts on the market, yeast deficits from high grav fermentation, and well known suggestions about reculturing yet you ALWAYS harvest ?!!? I doubt I average even 3 beers from a built-up starter. >process (set up, sanitization of the valve, harvesting and clean up) >takes less than 30 minutes. If you said 5 minutes I'd be impressed, but harvesting yeast when I'm kegging doesn't add even 15 minutes and that includes a water based wash(separation) before re-pitching. >>>1) trub removal with the flick of a valve >>"And constant attention looking for end-of-trub." >I haven't lost sleep over the end-of-trub. But it's not a 'flick of a valve' if you must monitor it. >>"The sideport design [...] >I usually lose between a pint to a quart [...] That's a good figure, but doesn't it vary as the yeast level varies from differing yeasts or brew volumes ? (re cleaning & durability) >>"Corny's would have the same advantages at 1/10th the cost." >The CC is ten times better as a fermentor, so it's a wash. ; -) Cute comeback - but you haven't cited any advantages that makes CCs even 2X better than cornies. As for cornies - they fit nicely in a fridge for temp control and the fittings lend themselves to fermenting with overpressure and using CO2 or N2 for air free wort/beer transfer. >Actually, it ran around $600. For that I could buy a large freezer & temp controller and still have enough left over for half a dozen yeast cultures and sacks of malt. Just how do you control temps for lager yeasts in a 12gal or Ant's 60L pointed CC tank ? >>Have you never had three brews bubbling at once?" > >I do, however, look back with fondness/horror on the >days when I was obsessed enough to have three beers brewing >contemporaneously. I am now happy to simply have three beers on tap at >all times. Three on tap is about right, but that means there are always 1 or 2 dwindling and my brewing schedule becomes clustered because of my work. Two beers in fermenters perhaps a week apart isn't unusual around my place. Hi-grav & small beers and side-by-side controls/comparisons are common here too. I need 2 fermenters, and prefer 3. >>"It's still just a racking cane alternative to me." >Like a Porsche is just an alternative to a Yugo. Very apt - if you drive frequently on the autobahn or on well paved roads in Montana you'd probably find a Porche's qualities desirable. If OTOH you live in Boston or a city east of Plzen you'd find the Porche impossible to navigate, park or keep from being stolen. A Yugo is a dud, but there are many applications where a Hondas qualities exceeds those of a Porsche and of course there is the opportunity cost of investing $100k vs $20k. If you are looking for a status symbol the Porche and the CC fermenter 'work' but that isn't my goal. Home brewing is (for me) only about beer quality and the sense of accomplishment, and makes no fiscal sense. When you tell me that you have a method that costs $500 per fermenter and has no impact on beer quality and saves me a little cleanup and a few minutes at yeast harvest per brew, I tune out. It doesn't help accomplish my brewing goals or match my brewing needs. The CC fermenters appear to me to fail a very basic test. No one has yet advanced an argument here that it improves beer quality, much less improves it *more* than alternative expenditures. I look forward to hearing about George Fix' experiments and results. >if one does not have practical >experience with a piece of equipment, one should limit one's criticism >of said equipment. I did limit my criticism. I said they were ghastly expensive and gave no demonstrated fermentation performance improvement. Also, you don't have to own the Porsche and Yugo to understand the basics and make critical decisions. - -- Frank Tutzauer writes ... >>would you really tie up your only >>fermenter for many weeks w/ 3.5 gallons of barleywine ? > >No, of course not. You put the 3.5 gallon barleywine in a carboy and >save the CC for other brews. And: If a CC fermenter had any quality advantages you'd certainly want to use it on all of your beers Frank. Would you really spend all that time making a barleywine and then compromise the quality by not using your CC ? >If you've >got a CC fermenter, that doesn't mean you're not allowed to ferment in >anything else. Having a car doesn't mean you can't take a bus, and having access to brewing yeast doesn't mean you can't brew with bread yeast - but you won't find many doing it exactly because the extra cost is justified by the quality or convenience. If you could get a *justifiable* amount of improvement or convenience from a CC fermenter as compared to their cost then we would use these exclusively too. My point remains that the cost of a CC fermenter is probably not justified for most of us. -S Return to table of contents

I don't have any answers for how to fix it, but just wanted to elaborate on Wyeast 1728 yeast. I recently used this yeast on a barleywine with an OG of 1.107. It fermented down to 1.021 at 55F in 5 days, so the yeast is definitely capable of fermenting at low temperatures and high gravities. I did rack the bw onto the yeast cake from an 80 shilling Scottish Ale fermentation, so there was plenty of yeast. The Scottish Ale was a 1.044 and finished at 1.011.

Date: Mon, 05 Mar 2001 09:38:10 -0500 From: William Macher <macher at telerama.lm.com> Subject: Said nipple, meant coupling! Hi All, When describing for Jeff how I made my bulkhead style keg fittings, I wrote: "Take a pipe tap and run it into the brass nipples a bit, to make it possible for the nipple to go in further." Naturally, the pipe tap can only go into the female couplings, not the threaded male nipples! Sorry for the confusion. Related to the brass couplings, I have seen two types locally. One is cast and the other is machined, like a piece of pipe with a thread inside. Find the cast type, as they have a nut-like hex end that offers more surface area to squeeze the teflon tape against the keg wall. You may also want to take a file, our use a sheet of abrasive paper, to smooth down the end of the coupling that will contact the keg wall to ensure a tighter fit. It only takes a few minutes and may help make a tighter joint. Bill Macher Pittsburgh, PA USA Pipe threads are tapered, that is way this is necessary. You should have no problem once this is done. A 3/8 pipe tap is much cheaper than a half inch one. That is why I decided to go with 3/8 inch valves and couplings, even though the rest of my system uses half inch copper tubing.

We have them, but there's not much feedback yet. They sound like a great idea though. We're experimenting with two thicknesses. I suspect the thinner ones will give a better seal with a bung in the neck of the carboy. We'd love to hear details from folks who are using them. cheers, Stephen Ross -- "Vitae sine cerevisiae sugant."

Bob, Liquid Bread (the guys that make the Carbonator cap) sells a regulator that fits on the BernzOMatic cylinders. I've got one and it works great. It even came with an inline connector, so you can easily detach the airstone and hose for boiling. I can't remember where I bought it, but I know I've seen these particular regulators via mail order (try Beer, Beer and More Beer, HopTech, Brewers Resource, St. Pats) if you local shop can't order it.

Date: Mon, 5 Mar 2001 09:10:06 -0600 From: Vachom <MVachow at newman.k12.la.us> Subject: Portland beer Alan: Happy travels to the balmy south! If the weatherman has it right, you may find Porland under several feet of snow. Travel safely. I recommend going to the Portland Public Market to look for beer. I think you'll find most of what you want there. I recommend stocking up on Allagash Brewing's products. This Portland micro-brewery brews a wit, a dubbel, a tripel, a Grand Cru and one other. They are outstanding American attempts at Belgian beers. If I were you, I'd bring them right back home and sit down for a Unibroue/Allagash taste test. I also recommend snapping up a bit of the Smuttynose Brewery's (Portsmouth, NH) Shoals Pale Ale. This brewery also has a Big Beer Series; their barleywine is very nicely done.

Date: Mon, 05 Mar 2001 11:36:43 -0400 From: AJ <ajdel at mindspring.com> Subject: Temperature Uniformity in Cylindroconicals Temperatures within a cylindorconical should be reasonably uniform as a mixing of the beer is one of the features of the design. Whether the chilling be from glycol (usual) or the Peltier coolers appearing on some of the smaller HB units, the "cold" is applied at the outside of the fermenter. Beer in contact with the walls is thus cooled and sinks forcing a welling up of warmer beer through the core. Thus there is constant circulation whenever the chill band is activated and this is augmented by the heat produced in the core when the yeast are at the height of their activity. Yes, there will be a gradient - it wouldn't work if there weren't but it should amount to no more than a couple of degrees F if that. A.J. Return to table of contents
Date: Mon, 5 Mar 2001 09:56:00 -0500 From: "Pete Calinski" <pjcalinski at adelphia.net> Subject: 1.024 sg and I already kegged it! Help!---Not from me Don, A few weeks ago, I posted a similar problem. I bottled a Scottish Ale with an SG of 1.032. I can't get it to carbonate and it is like syrup. I got a few good suggestions but none that would solve my overall problem, reduce the gravity and increase the carbonation My first hypothesis was that the yeast had given up because of the high alcohol level. It had started at SG=1.101 and ended at, as I said, 1.032. I opened one bottle, added a little rehydrated champagne yeast, and put a balloon over it. Nothing, the balloon inflated a little from the small amount of CO2 in solution but that was it. Next hypothesis, the champagne yeast was old and ineffective. I had a fresh 1056 yeast cake so I added some, about the size of a pea. Nothing again. Next hypothesis, on the outside chance that it was a lack of O2 that was keeping the yeast from acting, I shook the bottle, first to release all the CO2 then more until it wouldn't take up any more air. Still no action and still syrupy. My next hypothesis is, perhaps all the fermentables have been consumed. I plan to add a little sugar and see if it will inflate the balloon. If that is the problem, I guess I'll take Domenick up on his offer of Prime Tabs, pop open all the bottles and add the prime tabs. Maybe the syrup texture will be easier to take with more carbonation. If that fails, I need some more ideas.

Date: Mon, 5 Mar 2001 09:38:20 -0600 From: "H Stearns Laseur" <h_stearns_laseur at email.mobil.com> Subject: Singing the praises of ez-flip top (grolsch) bottles... <These bottles make bottling so simple, and I had a bottle overprimed, it> <simply hissed for a bit, and once the pressure got down to an acceptable> <level, carbonated up nicely..> <This is a no-go wrong solution imho, I purchased 12 1-liter bottles for> <around $25, and have about 50 20oz grolsch bottles that i emptied myself..> <very nice indeedy> I totally agree with your assessment on the grolsch bottles. I use the liter version which is more forgiving when stirring up sediment while pouring. Another bottle I like to use is a plastic green liter sprite bottle. The indentations on the bottom are excellent in trapping sediment while pouring. Don't be afraid of oxygen getting into your beer. I've used both the glass "grolsch" type and plastic liter coke bottles for years now, and I have never been able to tell the difference in taste or fizz. In fact the plastic bottles are more dependable for keeping the beer fizzed. No leaking gaskets to deal with. Now beer in my household only lasts about a maximum of six weeks per 5 gallon batch so maybe I don't keep the beer long enough to tell any difference. Another neat trait about plastic bottles are that they get hard when they are primed. There is a lot of play in the bottle when it is freshly filled with beer. You can thump the bottle on its side when it's ready to drink and the gas in the beer takes the softness out of the plastic and the bottle sounds like a ripe watermelon. You can't do that with the glass bottles. Plastic is also more forgiving than glass when you over prime. This said, glass is cosmetically more visual when you serve beer to friends than the plastic bottles. Remember Goliad! Return to table of contents
Date: Mon, 5 Mar 2001 11:18:41 -0500 From: "Czerpak, Pete" <Pete.Czerpak at siigroup.com> Subject: taste of a bitter?? I brewed a bitter maybe 6 weeks ago using Wyeast 1968 that went from about 1.036 down to 1.006 -1.008. All british hopping to perhaps about 35 IBU. I don't have my notes on the grain bill and the batch was mashed to 154F. It was batch sparged also per my normal procedure. The aforementioned 1968 then went on to brew an ESB and then a imperial stout. The bitter brew smells malty and has a decent bitterness. It was mash hopped by the way. My question is that the brew tastes a bit on the thin side. It was just barely carbonated and normal fridge temp (upper 40s) when I tasted it. I have been to the UK and it doesn't taste like a normal british bitter. any ideas? Does bitter normally taste thin if not drawn on a hand pump? Perhaps a few more days of conditioning under gas... I haven't had a homebrew bitter so don't know quite what to expect. Its time to find a new england beer festival for the month of March. I got to the Winter Ales Festival in the UK in January. And the Tornado Barley Wine festival in Feb. Hope March brings another good one. Incidently, the barley wine festival was excellent. We were there the first day and it was crowded due to rainy SF weather. My group did sample all the barley wines atleast once. many were tried multiple times. another quick note, I managed to pick up a new counter pressure bottler (not Phils) a few weeks ago at a competition. Anyways, I already have a Phils version and was wondering if anybody might be interested in this new one I recieved. I prefer some sort of trade for it but might accept money for it. make me an offer off-line if you would like a CP bottler. It still needs lines and keg fittings though. otherwise, its brand new and never used. 2 valves at the top for beer and CO2. third valve just above where the bottle would go for purge/foam relief. Have fun brewing and tasting, Pete czerpak albany, NY PS. I think that with all the interest in carafa malt lately, perhaps NOrthern Brewer might start carrying it. I would certainly try to get it from them first if they did. Hint, hint.... Return to table of contents
Date: Mon, 05 Mar 2001 10:35:58 -0600 From: The Freemans <potsus at Bellsouth.net> Subject: conical cooling First let me say that I purchased the 12.2 gallon stainless conical from Beer, Beer, and More Beer (NAYY) several years ago. I did this for a variety of reasons, not the least of which is that glass fermenters and I simply do not play well with each other. I, for one, do not regularly try to save yeast, but instead choose to retain all my fingers and toes. At the time, There was no cooling option available from B3. They now have two alternatives to solving that problem. B3 is using a series of Peltier effect cooling units. Peltier effect thermoelectric cooling is not a new discovery having been first realized in the early 1800s. This thermoelectric cooling (or heating BTW) refers to the reversible heating or cooling which occurs at the contact point when current flows from one connector to another. B3 uses this technology in the form of 2 Coolworks type "ice probes" placed through the conical wall (read $390) or by a series of Peltier junctions placed on the outside surface of the conical (read $790). An insulating blanket is supplied to help retain the cool. The conical is not "jacketed' in the formal sense of the word as personified by glycol jackets. Now, I am considered by brewing friends as the ultimate "gear head" (with the possible exception of Zymie and his IGOR) when it comes to brew gear. "the perfesser" incorporates two PIDS, an electric HLT, and a heat exchanger system. It also has a mash tun mixer similar to but much smaller than a commercial unit. Put this together with an in-line aerator and a grant and there is little else I can think of to add. All this leads me to the fact that I find the cooling alternatives available for the conical as being out of the range of even my brewing investment capabilities. With the addition of Peltier surface units, we are talking about an investment of $575 for the conical plus $790 for cooling. While I can justify the conical in terms of fingers and toes, (I really am a klutz) I cannot justify the thermoelectric cooling. I will however entertain any offers of a cooled conical for "test" purposes". I solved the cooling business much as Richard Sieben suggested. I put the whole conical in a big 6 1/2 foot tall by 6 foot wide recycled Beverage Air cooler I obtained form the local Pepsi distributor for the sum of $100 (guaranteed to run) plus I added a digital temp control. I may not get 1 degree C accuracy from this set up, but hey, it works for me. Most of my brewing during the summer is done with cooling in order to get below the ambient 90-95 degree weather. It may cost a bit to run this cooler, but I can buy a lot of electricity for $790. http://www.coolworks.simplenet.com/coolproducts.htm http://www.brewrats.org/hwb/er Bill Freeman aka Elder Rat K P Brewery - home of "the perfesser" Birmingham, AL Return to table of contents
Date: Mon, 5 Mar 2001 11:45:30 -0500 From: "Peed, John" <jpeed at elotouch.com> Subject: Mash questions I bought the ProMash program and am familiarizing myself with it. I'm not sure I understand everything I know about it just yet, and it has raised some questions in my mind. First, is it OK to have an extremely thick mash when doing a protein rest? It had better be, because if the sacrification temperature is to be reached by infusion, you don't want to start out with anything less than a very thick protein rest mash. Second, even with an extremely thick protein rest mash, the temperature of the infusion water required to reach sacrification temp is going to be on the order of 180 to 190 degrees. Most of my past reading says not to exceed 170 degrees for strike or sparge water, due to the probability of leaching tannins from the husks if hotter water is used. I have a RIMS system, so I can heat and recirculate and make the step that way, but it will take 15 to 20 minutes. I have read that you want to make the steps as quickly as possible for various reasons (avoid thinning out the body, etc.). So which is the lesser of the two evils? Quick temperature boosts at the expense of high water temps or RIMS temperature boosts at the expense of speed? John Peed Knoxville, TN Return to table of contents
Date: Mon, 05 Mar 2001 12:17:17 -0500 From: Nathan Matta <whatsa at MIT.EDU> Subject: Room-temp storage I understand that it is preferred to store beer at low temps (close to freezing) in pretty much all cases. What sort of problems would be anticipated from storing beer at room temp (~70 F)? I have 2 batches that were brewed consecutively, reusing yeast from one to the next. Both of them were quite tasty, but have now developed (at about the same time) an off flavor that most often manifests as alcohol bite. The only thing I can think of that might have caused this would be the fact that they were not kept below room temp. They're still drinkable, but definitely not as enjoyable as before. Bummer...

I'm hoping that I'm not the only one having this experience. I've just been turned on to a tablet, Whirlfloc, which is a clarifier like Irish Moss. I've had a few batches lately that after cooling, I wind up leaving more than a gallon behind in the brewkettle, because of all this gelatinized blobs of trub that won't settle out in the middle, and I'm afraid to rack them into the primary. I've quit using the whirlfloc, once I figured out that that's what was causing this. My question is, am I the only one getting these weird globs, or am I just paranoid about letting those compounds into the fermenter? I imagine they'd settle out, and I'm pretty much bummed about having a scant 3 gallons of my IPA ready to drink... Thanks again for all the great advice! brent electric dog brewery not sure of the exact coordinates, but pretty far W, and probably a bit S Rennarian... Return to table of contents

I bottled a bitter using a very low level of priming (1/2 cup DME for 6 USG) so this may not be generalizable to other beers or to glucose. I usually fill to 1/2 inch of the top, then squeeze all of the air out before capping with the screw cap (that should make up for about 6 months' oxygen permeation). I left the air in two 600 mL bottles, and put aside two identical bottles without air. Carbonation of this batch was slow (10 days) due to low priming and the very flocculent yeast giving me a low cell count for priming. I couldn't detect any difference between the with-air and without-air bottles as far as speed of carbonation or level. So I am inclined to go for the CO2 inhibition hypothesis until someone can debunk that too. Sean Richens srichens at sprint.ca Return to table of contents

I must say I am quite impressed! One final question on this George, was the lower temperature probe down in the yeast or above it? My only real concern is the actual temperature of the yeast itself so that it doesn't start to autolyze early. (yes even i can live with the blasted ball valve, though I am not real happy about that) It may well be that the volume is small enough to allow the cold to penetrate the yeast, but I would like to know for sure.
