A full featured professional conical fermenter for home use. The Grainfather Conical Fermenter Pro Edition give the home brewer professional liquid jacketed fermentation control, the ability to purge yeast sediment, take yeast and beer samples, and transfer wort via its innovative dual function valve design.

DOUBLE WALLED: A stainless steel double walled skin is filled with a thick layer of polyurethane foam for insulation. This keeps the wort at a constant stable temperature with minimal influence from any external environmental temperature changes, providing insulation for your fermentation that a standard jacket cannot achieve.

INTEGRATED GENTLE HEAT: In the cavity of the fermenter between the outer body and cone sits a 30 Watt, 12V heating element. Unlike standard heating elements/sources that directly heat the liquid, this heat source is designed to heat the environment in between the walls of the fermenter, which in turn heats the liquid. It is similar to controlling the temperature in a temperature controlled room. The fermenter acts as an artificial environment which can be heated, meaning the temperature is raised in an even manner which is much better for the yeast than using a localized heating pad or belt heater.

BUILT IN COOLING SLEEVE: In between the two stainless steel walls sits a liquid cooling sleeve. This stainless sleeve is welded onto the inner wall of the fermenter and can be hooked up to the Glycol Chiller or water pump (submersible 12 volt pump included). Temperature is dialed into the front panel Temperature Controller and as the cooling liquid travels through this sleeve, it cools the stainless steel which in turn evenly cools the beer in the fermenter. The cooling sleeve never comes into contact with the beer, it is completely concealed, built into the fermenter and never needs cleaning or sanitizing. Besides even heat, the beauty of this sleeve is that nothing protrudes into the fermenter, making cleaning and sanitizing much simpler than say with a submerged cooling coil. The cooling sleeve features ½” female thread inlets and outlets, so it is easy to connect cooling water with a simple threaded hose barb.

60° ANGLE CONICAL WALLS: The conical shape of the fermenter is typical for professional breweries. The Grainfather has been designed with the ‘Golden Angle’ of 60º. This is the optimum angle for yeast and sediment to drop down to the bottom of the cone without getting stuck to the sides, allowing you to transfer from above the sediment line, resulting in clearer beer.

DUAL TAP VALVE: Sampling and transferring is done through an inlet above the sediment line, allowing for clear, sediment free beer. Easily collect your yeast from below the sediment line with the lower port on the same valve.

DIGITAL CONTROL: The Temperature Controller allows you to accurately dial in a temperature and even set a temperature schedule/profile (you can set up to 4 profiles each with 5 stages). It can control the heating of the integrated heating element and the cooling if you get the optional Grainfather Conical Cooling Edition (see photo at right), turning on the heater or water pump as needed to maintain your preset temperature. The Grainfather Conical comes with a 2 year warranty from date of purchase. All liquid contact points are made of type 304 stainless. 8 US Gallon capacity (volume markings on inner body up to 7 US Gallons). 36” tall with airlock, 13” wide.

This cooling edition includes a cooling hose kit with 12 volt submersible pump (controlled by the Digital Control) for use with an external cooling water source. A cooling water source can be as simple as a bucket of ice water, or as sophisticated as an Icemaster Glycol Chiller (see our item Z40 at right).

I am wondering if the submersible pump is able to be purchased separately in case one goes bad?
The pump is not sold as a stand alone item and is only sold as a kit. While we don't sell the kit at this time, you can find similar pumps on eBay.

Does the cooling kit need any additional fittings to connect to the cooling jacket?
No, if you buy the Cooling Edition, it comes with hoses and connections to connect to the Grainfather Conical cooling jacket. It also comes with a submersible pump to put in a cold water bath, or a glycol chiller like our item Z40.
