dosing fermcap in the fermenter
« on: December 09, 2013, 10:09:03 AM »
I already used some in the boil, but seem to have alot of foam in the fermenter when i went to oxygenate. Is it ok to add more in the fermenter?

You can, but hefe yeast has a mind of its own. Fermcap may help, but 20% headspace may still be cutting it a bit close even with the Fermcap. I'd have a blowoff tube rigged up just to be on the safe side.

Even with fermcap, I've never been able to keep 3068 in the carboy.

 On 3068 - I use 8 gallon fermenter buckets now for 5.5 gallons (usually) and the last time I used 3068, I had krausen foam evenly across the bottom of the bucket lid, and that's with 2.5 gallons of headspace. Pretty vigorous stuff.

I had the same issue with wyeast 3787, I bought some Fermcap in hopes of keeping it in the fermenter, but no luck.

Yeah that stuff's crazy active, too.  I think I fermented it @~ 64F last time and it seemed every bit as active as 67 or 68F.  Good stuff though.
