What i did: I brewed a high octane Doppelbock in the 18 Plato range, let it ferment for 6 weeks, transferred it to a clean container 60 l or 16.something gallons. (We use high density PE containers with a spigot and a 10 inch opening with screw on cover. It's easy to get and quite cheap around here, it's mostly used for cider. After reading several HB books, i thought i need glass fermenters, but these PE containers prooved to be the right thing for us. They are very practical, have handles and don't break.) I cooled it down to -5 C at first to see crystals forming, it was not enough. So i cooled down further 1C a day until i saw the first crystals. I thought it's best to cool down slowly to let the water and beer separate. I skimmed of the crystals with a sanitized sieve and cooled it down some more. I repeated the process, until i had removed around 20% of the volume. Then i kegged and carbonized it. This beer was quite a blaster, but i only did it once. It concentrates every taste, it's a bit hard to predict how it will taste, since it can put a perfectly balanced brew off balance when concentrated. If i do it again, i would brew a "lighter" beer to start with, maybe in the 15 Plato OG range. (By the way isn't it forbidden to do this in your country, around here it actually is, since it's a form of concentrating alcohol like distilling.) Cheers Thomas Return to table of contents

The problem is not with the design or implementation, but your use of it, or in this case, your misuse of it. Probably my fault for not making my RIMS pages more detailed on use. What you describe is *exactly* why I tell everyone who asks me directly about RIMS that after *every* brew, the heater elements must be taken out of the heater chamber, the elements themselves lightly gone over with a scotchbrite pad, and a straightened carboy brush run through the heater chamber itself. The elements and chamber are then hung up to dry for several days and not re-assembled until bone dry. With these disassembled, getting everything clean and dry is a piece of cake. Once disassembled, the heater chamber is *easy* to clean. And, I find that the chamber itself never gets any crud built up in it that cannot be removed with a light brushing with hot water only. Yes, if you try to accomplish this with clean-in-place techniques, this will fail miserably. This design is *not* conducive to CIP techniques. I totally agree with you that clover tri-clamp fittings would make this job easier, but for those who do not wish to buy these, a large crescent wrench makes this an easy job. The heater elements should not be screwed in too tight anyway, as you do not want to deform the rubber gasket. They can *almost* be screwed out by hand, but not quite. When tightening, I recommend screwing in until finger tight, then using a wrench to turn 1/4 turn more only. Thanks for pointing out the deficiency in my explanations. I will try to find some time to correct this on my web pages so others do not have to go through this problem discovery process. regards, dion - -- Dion Hollenbeck Email: hollen at woodsprite.com Home Page: http://www.woodsprite.com Brewing Page: http://hbd.org/hollen Return to table of contents

You could just cellar it. I did that with a Pale Ale that got fermented at too high a temperature with some 2nd hand WLP001 yeast that might have gone astray. It was horrable, and others agreed with me. You'd swear the main ingredient was nail polish remover. A little over a year later it took 3rd place as a Belgium Pale Ale. - --Jeff H.

Date: Tue, 8 Aug 2006 08:09:54 -0700 (PDT) From: Matt <baumssl27 at yahoo.com> Subject: what to do with fusely beer Peter Ensminger is trying to find something to do with a fusely braggot. The phrase "fusely braggot" just sounds bad, for one thing. Anyway, one brainstorm was to add yeast and honey in the hope that the fermenting yeast would get rid of some of the fusels by esterifying them. I doubt this will work because, at least for the numbers I have seen, even in a normal 5G fermentation the percentage of fusels that are turned into esters is very very small. It seems unlikely that this would be different in an "auxillary" fermentation--my guess is that he'd end up with even more fusels. Another brainstorm is trying to "soak" the fusels into oak/charcoal. For that matter, is there any substance at all that can be added to beer that will react preferentially with fusels to produce a (safe) flavor-neutral or -positive product? I have no idea myself. Barring that, I think there are two options. First, fusel levels could certainly be reduced by the simplest means: dilution. Second, one could attempt to cover up the fusels with strong flavors. Perhaps a combination of these simple plans is best. Assuming he wants to limit the effort to something short of brewing a "dilution beer," Peter might, for instance, simply dilute the beer and dry-hop (or dry-herb) it. A step further would be to steep a couple pounds of specialty grains in 2 G of water, add this to the 5G of braggot, and add a yeast of great character like Safbrew T-58, or a weizen yeast, or even a big brettanomyces clausseni starter.

Date: Tue, 8 Aug 2006 08:35:25 -0700 (PDT) From: Matt <baumssl27 at yahoo.com> Subject: Safbrew T-58 I recently used Safbrew T-58 for the first time. This is a dry yeast that is advertised as having an estery, spicy, peppery profile. I enjoy the convenience of dry yeast, so I was interested to try the only dry "Belgian" strain I know of. I haven't seen too much information posted on this strain anywhere, so I thought I'd post my experience. Tossing 20 grams (2 packs) into 5 gallons of a wheat beer wort, with no rehydration and almost no aeration (as the yeast cells are said to be pretty "well-stocked" when they are dried), fermentation was fast and strong. The resulting beer had a lot of very nice tropical fruit esters and is really one of the better wheat beers I've had. The yeast was pitched at 70 degrees F, and the ferment was at 70-74 degrees. No yeast nutrients were added. I don't know the yeast's origin, but the tiny Picobrouwerij Alvinne in Belgium uses it for some of their beers (as stated on their website).

It might be possible, but I suspect you'd always know they are there. As > 2) Add charred wood staves to the keg to "soak up" the higher alcohols. This should work, but if you don't want the oak flavor try activated charcoal - aquarium supply places carry it.

See the discussion in: > http://hbd.org/hbd/archive/4459.html#4459-9 and #4459-10 It could work, but I doubt it. Yeast normally only convert a modest fraction of the fusels into esters. Would a 20-30% reduction in fusels (being very optimistic here) solve your problem ? *MAYBE* you could encourage a higher conversion rate by yeast selection, ester enhancing fermenting conditions, or by adding carboxylic ester precursors. -S Return to table of contents

But consuming alcohol is > likely to be counterproductive: > http://www.drgreene.com/21_1907.html > Interesting read, Dylan. But I think the research has missed the mark, since it only deals with the effects of alcohol. Obviously what is needed is some research into the effects of beer. As David Harsh wrote, it might be compounds in hops that have a benificial effect. I for one would like to hear a followup on this! Later. Andrew xxx Return to table of contents
Date: Tue, 8 Aug 2006 16:50:32 -0700 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: Re: Pre-made sanitary fittings Teddy asks about pre-made sanitary fittings and tube "The problem with this setup is that the heating element goes in the T then into the pipe nipple." I'm sure you could order it made up from any one of a number of places (but not cheaply). You would actually have the whole heating chamber made out of butt-welded tubing with ferrules only at the entrance, exit and heater locations. This would drastically reduce the number of tri-clamps and fittings you'd need. I could recommend someone to do it for you...but have you considered using Swagelok fittings instead? I have a similar setup (but with a T at each end and a thermometer in the T opposite the heater) but the T fittings are 1" Swagelok. The whole thing comes apart with a wrench, and since it's not under a lot of pressure, it doesn't need to be all that tight in the first place (they even make Teflon ferrules for Swagelok, which doesn't have to be much more than finger tight). If you get a reducing Tee, you could use a standard cartridge heater, and swage it directly into the run end of the T. A Swagelok fitting is pretty darn smooth on the inside--no place for solids to get trapped, as in the case with threaded nipples, couplers and pipe.
