It worked wonders on my latest rye PA -- but I had to add a bit more than recommended. The stuff is harmless, so that's fine. It is also cheap, which makes it even better!chriso said:Flyguy, good to know Fermcap works even on wheat/rye's. I just might buy some + give it a whirl. I've not used a blowoff yet since I usually run 5 gal in a 6.5 but I'm planning a couple of mostly wheat and mostly rye brews in the next 2 mos.
Yes, if you are interested in some of the research I found online and the procedures that I personally do, here's a link. Also, a guy named Poindexter did an experimental batch as well on this link. If you have any questions or anything feel free to ask. As for this thread, I don't use an airlock. I use a spunding valve. Here's a link to Poindexter's, which are parts I wish I used on mine when I made it (pressure gauge and adjustable relief valve, I like the brass "T" better on mine, but I am also in a bigger keg than he is). It is just a different approach.gyrfalcon said:Can you ferment under pressure?
