End of line clearance

The price of the conical has been reduced to reflect that an updated wifi model will be coming shortly to replace this model.


Double Walled: A stainless steel double walled skin is filled with a thick layer of polyurethane foam for insulation. This is what 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 Heating: 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 and controlled manner which is much better for the yeast.

Integrated Cooling Sleeve: In between the two stainless steel walls sits a cooling sleeve (also made of stainless steel). This cooling sleeve is welded onto the inner wall of the fermenter and can be hooked up to the additionally purchased Glycol Chiller. Temperature is dialled into the 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 sanitising – a true innovation for a fermenter of this scale.

Easy Access to the Interior for Hassle Free Cleaning: The Grainfather Conical Fermenter has a smooth interior with no additions such as cooling coils or additional sampling valves meaning it is easy to clean and minimises the risk of infection.

Golden Angle Conical: The conical shape of the fermenter is typical for professional breweries. Our conical 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. The conical shape also allows for better mixing during fermentation due to the path of convention currents that it enables to occur.

Dual Valve Tap: Make the yeast dumping, transferring and sampling process more professional with this innovative all in one 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 same unique valve for re cultivating and pitching. The innovative design of the valve allows for this dual functionality and less cleaning for you.

Temperature Control: The Temperature Controller easily snaps on and replaces the standard Temperature Display via magnets and pogo pins. Allowing 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 have upgrade to the Glycol Chiller).

Support: The Grainfather Conical Fermenter is fully supported around the world by a fantastic support team who love brewing just as much as you do. All Grainfather Conical Fermenters come with a 24-month warranty.

    Hands down my best brewing purchase barring the Grainfather itself (would be 5 stars if you could pressure ferment). Added in a cooling pump kit and it’s perfect for temperature controlled fermentation. Easy to clean, lovely to look at and the dual valve makes trub dumping, yeast harvesting and sample taking a breeze. Excellent bit of kit unrivalled in the world of homebrewing fermenters in my ten years plus of homebrewing.

    Awesome – in a word . With a Glycol chiller as an excellent partner gives accurate temperature control for fermentation and cold crashing . Waiting to justify my second one !
