Upgrade from those heavy, breakable, flat-bottomed glass carboys to the Grainfather Conical Fermenter for the ultimate control and flexibility. The innovative Dual Valve Tap makes yeast dumping and harvesting, transferring and sampling extremely simple. Sampling and transferring are 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 for discarding or reuse.
The Grainfather Conical Fermenter has been designed to give you the best in fermentation control.
Utilizing the “Golden Angle” of 60°, the optimum angle for dropping yeast to the bottom without clinging to the sides, this is the perfect fermenter for dumping or harvesting yeast for reuse. It's never been easier to control your fermentation temperature, minimize oxygen exposure, and clean up quickly.
Control the fermentation by simply setting your optimal temperature with the Digital Controller to customize the exact flavor profile of your yeast. You can even program up to 4 fermentation profiles, each with up to 5 temperature stages.

This is a great piece of equipment, especially if you can get it on sale. But buyer beware: while this has the capability to cool your wort, you have to buy an additional cooling packet to do that, AND you need a glycol or other cooling system to actually cool the wort. Still, this is a good buy. I have this as a supplement to my SS Brewtech unitank and glycol chiller. Both work well, but the GF system is significantly less expensive.
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.
