Grainfather Conical Fermenter - Pro Series

SKU: U42339

Optimize your beer's flavor profile by utilizing the controlability of the new Grainfather Conical Fermenter - Pro Series. Complete with the Grainfather Digital Temperature Controller and Dual Valve Tap, the functionality of a commercial brewery is now at the homebrewer's fingertips. Its double-walled stainless steel construction provides rigidity and insulation, and with the integrated heating element, your wort will remain in the optimal fermentation range for any yeast strain.

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.

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.

Does this pro edition come with the digital temperature controller and the original digital display? Or is it only the digital display that comes included and the digital temp controller has to be bought separetly?

Can hot wort be poured directly into this, then use the glycol chiller or cooling pump to bring the wort temperature down for pitching yeast? Or do you still have to chill wort first, then move it to the grainfather?
Kenneth N on May 22, 2018
BEST ANSWER: From reading the instructions, it does not seem like it's intended to chill the wort direct from the brew kettle. I'd advise chilling it before adding it into the conical fermenter, and then using the cooling pump/glycol chiller to hold it at the precise fermenting temperature.
Does this come with the Cooling Pump Kit? It's pictured in the photos but I don't see it listed in the description as being included.
A shopper on May 14, 2018
BEST ANSWER: It doesn't not come with it. It is in a drop down on the page as a add on for 79.99. It is called a Pro Edition but it still has upgrades you can buy.I ordered mine when they had a 20% off sale and the cost was awesome on the whole unit. I ordered all items except yhr glycol unit. I wanted to try cold water chilling first.
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?
A shopper on Oct 2, 2017
BEST ANSWER: We recommend trying to only heat about 10 degrees above ambient.
