hey, i read through a bunch of threads on it but got mixed results. when using frozen bottles to keep fermentation temps down, is it best to surround the carboy with water and let the frozen bottles float in water....
or just put the frozen bottles around the carboy and no water at all?
i have my glass carboy in a cooler full of water(no lid though), and ive been adding frozen bottles, usually 2 at a time....but they melt VERY quick
