Thanks, Joe, good idea about warming up a test bottle, I'll try that.

For the minimum sorbate levels, I've got a couple of tables that
determine the minimum required level based on the alcohol and pH; I
think the original source for this is Peynaud.

With the "sterile" filter, how much bypass would you get these days on
a 6 gal batch?
