---------------------------------------------------------------------- Date: Thu, 22 Dec 2005 13:14:59 +0000 From: "A.J deLange" <ajdel at cox.net> Subject: Sight tube Mike, You're making me feel like a grammar school teacher! Anyway I don't see much wrong with what you are saying. In fact I think the idea of using a Magnahelic (or better yet a Photohelic for automatic level adjustment) is a great one. Presumably you want to hook it up to the vessel through a length of tubing because you don't want wort or water in it so you could use a couple of feet of clear tubing going up the side of the kettle and put the meter in a convenient location. When you fill the vessel water enters the tube compressing the air in it and this will rise a couple of inches into the tube. Measure this and subtract from the inches of water reading on the instrument. This correction will vary with the amount of liquid in the vessel (as the pressure at the bottom varies) but you should be able to come up with a correction table or curve pretty easily. Another approach would be to put a pressure sensor which can withstand heat and wetting at the bottom of the vessel. All this is sort of klugey but let's face it, that's half the fun. A.J.

Date: Thu, 22 Dec 2005 10:35:01 -0400 From: Kevin Brown <kbrown at uvi.edu> Subject: Re: Duvel Clone incremented feeding Mark Tomusiak stated: I made such a beer last year, using WLP570 (Belgian Golden Ale) and closely following the reported Duvel brewing methods (started with a lower gravity wort, fed sugars during fermentation, etc.), including lagering at close to 32 F for an extended period of time. The resulting beer was outstanding, with a flavor and appearance profile very close to the original. I would like to hear a detailed description of your brewing process. I am gearing up to brew a Duvel clone and several other Belgians during my Holiday recess. I interested in what type/quantity of sugar you used for the incremental feeding and the time line. I have visited the Duvel website and gleaned some from there but if someone here wants to share their experience then that would be great. Happy Holiday!

I agree that it's probably your mash, because it almost certainly isn't your yeast. Repitching almost guarantees high cell counts. It may lead to mutated yeast or infected beer if you aren't careful, but incomplete fermentation is really unlikely.

If you have any questions about our upcoming programs (including our January web-based Concise Course and Executive Overview Course), please drop me a line at klemcke at siebelinstitute.com.

Date: Thu, 22 Dec 2005 11:23:58 -0800 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: CO2 MFM Ken Anderson took the time to post his rig on the web, and I have a couple questions. Nice rig, Ken. What's the maximum range of your meter? Also, 100 feet is a long way to take a 0-5 VDC signal. If one were buying one from scratch, the 4-20 mA signal model would be best. A current-based signal can go the distance without worrying about the resistance of the signal wiring. Then if your data acquistion needs a voltage, you use a precision resistor of the appropriate size across the terminals to translate the current back to a voltage. Some instruments will do either voltage or current (they sometimes have their own internal resistor), but it looks like Sierra wants you to buy a different model. When I saw your setup, I thought it might be useful to take a Mason jar and put it inline between the fermenter and the meter, with the hoses penetrating the lid. This would give you a larger volume to catch condensate and krausen. If you were tricky, you could put a "blowoff" hole in the lid with a weighted seal (like a pressure cooker uses), and put a float ball in a small cage in the outlet hole, so that if you did have a large amount of blowoff and you didn't catch it in time, the float would seal the outlet, and the pressure would blow out the blowoff hole. I was also interested in how you sealed your keg fermenter. Could you explain that in a bit more detail? It looks like a piece of lexan, with a rubber gasket sandwiched between it and the keg top. Is that right? Regards, Mike Sharp Return to table of contents

I'd rather go simple, since I remain a notebook brewer, and an interface akin to regular top-loading balance would be ideal. Anyone have any ideas for starting points? Thanks!

Also anyone have a site that has plans to build a beer engine? Or know of a source to get casks (or how to make one) to condition the ale in? Thanks Bill Kunka Return to table of contents
