Grainfather Conical Fermenter

SKU: U42339

Improve the flavor profile of your brew and give it the fermentation environment it needs to ferment correctly. With the optional digital controller, the Grainfather Conical Fermenter gives you the power to set your fermentation temperature. It’s double walled stainless steel construction provides insulation, and with the integrated heating element and optional Cooling Pump Kit, your wort will remain in the optimal fermentation range for any yeast strain.

Upgrade to the Dual Valve Tap for the ultimate flexibility. This innovative valve makes yeast dumping and harvesting, transferring and sampling processes extremely simple. Sampling and transferring is done through a valve above the sediment line allowing for clearer beer, while the incorporated dump feature allows you to collect yeast from the bottom of the fermenter.

The Grainfather Conical Fermenter has been designed to give you the best in fermenting performance! It was designed with the “Golden Angle” of 60°, the optimum angle for dropping yeast to the bottom without clinging to the sides. Make the jump today and control your fermentation temperature, minimize oxygen exposure, and clean up in minutes.

Digital Controller
Control the fermentation temperature by simply replacing the included temperature display with the Digital Controller to accurately dial in the ideal temperature and also includes an option to set up to a 5 stage temperature schedule.

Cooling Pump Kit
The Grainfather Cooling Pump Kit makes it easy to lower your fermentation temperature of the Grainfather Conical Fermenter. Operated with the Digital Controller, it’s designed to regulate and stabilize the fermentation temperature by pumping cold water through the double jacketed walls. And in just one fell swoop, you can target the perfect temperature for better beer! Simply connect the couplers and insulated hoses to the Conical Fermenter and pump, submerge the pump into the cooler of ice water, and the Cooling Pump Kit will circulate cold water through the jacketed walls of the Grainfather Conical Fermenter body as needed to sustain the desired fermentation temperature.

New conical
First impressions are that it is well made. After getting all the parts together like the cooling kit and digital controller noticed a glaring lack of any instructions for programming the controller or which hose goes to the small cooling pump outlet/ inlet. Attached the hoses per the online videos and was skeptical about the brass connectors with no taper or seals going into the walls of the cooling jacket on the unit. Leaked from both fittings onto the floor but I was doing a pre beer test run, but still not fun cleaning up water of my kitchen floor. Also the dual valve tap seal for the lower ball valve unit was already deformed and not in place / twisted/ deformed. It seems as though the small details are overlooked on this unit. Seals that are too flimsy for the sampling valve, not enough space to work between the legs , and iffy cooling connectors. Also water stays in the cooling jacket when cooling is disconnected letting the residual flow onto your floor. Seems like a check valve would have been nice. I bought the unit under no illusions and knew it had some drawbacks, but how much is too much?. Time will tell.

Would this be OK to use in a garage where the temp could drop to 20 degrees?? Would it be able to keep it warm enough throughout the fermentation process?

BEST ANSWER: We recommend trying to only heat about 10 degrees above ambient.
