Revolutionize the art of All-Grain homebrewing and give your Grainfather Connect the ultimate brewing companion. The new Grainfather Conical Fermenter allows you to ferment like never before. Featuring a doubled wall stainless steel fermenter filled with thick polyurethane foam insulation that keeps your wort at a stable temperature without worry. But that’s not all, you can heat and cool your wort with the integrated heating element and integrated cooling sleeve that connects to the Grainfather Glycol Chiller (coming soon).

For even better control over the fermentation temperature, simply replace the temperature display with the Digital Controller to accurately dial your temperature settings or set a temperature schedule/profile.

The Grainfather Conical Fermenter was designed with the “Golden Angle” of 60°, the optimum angle for dropping yeast to the bottom without clinging to the sides. Attach the innovative Dual Valve to the bottom of the cone to collect, sample, transfer, and dump yeast with ease.

Make the jump today and control your fermentation temperature, minimize oxygen exposure, and clean up in minutes.

Excellent Control
Already a Grainfather owner and fan, the fermentor is compact, easy to use and clean. I recently did my first brew with the temperamentalWyeast 3724 Belgian Saison strain that likes to ferment hot (88-90F). This fermentor kept it right where it needed to be and moved right past the dreaded 1.036 stall (open fermentation). It was simple and easy to drop the trub out and sample the beer for hydrometer readings (through the dual valve). Great piece of equipment just like the Grainfather.

is there a version of 220VAC 50Hz power for international use for heater and glycol chiller?
A shopper on Sep 23, 2017
BEST ANSWER: Thanks for contacting Northern Brewer. I understand you are looking for a 220vac Grainfather Conical Fermentor. At this time, we are only selling the 120 volt system as that is the rate of current used in the United States. Cheers!
