Take control of your fermentation by giving yeast the perfect environment to optimize your beer flavor profile. The Grainfather Conical Fermenter - Pro Edition features double-walled, stainless steel construction for durability and insulation and INCLUDES the Dual Valve Tap and NEW Conical Fermenter Pro Controller.

Use the Dual Valve Tap to take samples and when fermentation is finished, dump or harvest your yeast from the cone and transfer your beer all with the same valve. Samples and transfers are pulled from above the sediment line allowing for clearer beer while allowing for yeast collection from the bottom of the fermenter.
