The New Conical Fermenter PRO from Grainfather

We're excited to introduce the latest upgrade to the Grainfather Conical Fermenter that come with a 3 year warranty as standard.

Wireless Connectivity

The Conical Fermenter Pro comes with an upgraded built-in controller with wireless connectivity and improved digital display. This means yoU can now connect the controller to the internet and Grainfather App, and track fermentation with automatic alerts and notifications from wherever - at work, playing golf, fishing...anywhere with an internet connection. 

Full list of features for the Conical Fermenter Pro:

  • New controller that’s built into the fermenter with wireless connectivity and improved digital display
  • 30L (7 US Gal) capacity
  • 304 stainless steel, double walled body, for constant and stable temperature control
  • Dual valve tap for easy yeast dumping, transferring, and sampling
  • 30W, 12V heating element inside the cavity of the fermenter, which heats the environment between the fermenter walls, allowing for even/controlled increase in temperature
  • Connect the Cooling Pump Kit or Glycol Chiller to the integrated cooling sleeves that are welded to the two fermenter inner walls for even cooling
  • 60-degree (Golden Angle) cone for optimum yeast/sediment drop down, giving you clearer beer
  • Heating capabilities that can achieve up to 10˚C higher than ambient room temperature*
  • When used with the Cooling Pump Kit or Glycol Chiller, cooling capabilities that can achieve as low as 4˚C*

*Results will vary depending on the ambient temperature and humidity. Efficiency can be improved when using the Conical Fermenter Pro Insulation Jacket.

Ferment like never before!

The Grainfather Conical Fermenter give the brewer professional fermentation control, just like the commercial breweries. Fermentation is arguably the most important part of producing a good quality beer. A good fermentation environment starts with a clean and sterile fermenter, has a consistent controlled temperature base and exposure to oxygen is minimised.

The Grainfather Conical Fermenter provides you with a modular system for all of this and more!

The Grainfather Conical Fermenter Pro Edition includes the basic unit plus the Dual Valve Tap and Temperature Controller. Allowing you to control the heating of your unit, dump yeast, take samples and transfer your wort via our innovative dual function valve design.

Please Note: you only need the Glycol Chiller Cooling Connection Kit if this is your second, third or fourth conical fermenter as the Glycol Chiller comes with one connection kit.


  • 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. Temperature is dialed 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 recultivating and pitching. The innovative design of the valve allows for this dual functionality and less cleaning for you.
  • Wireless Controller: 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 with wireless connectivity and improved digital display.

    Grainfather conical fermenter.

    Very good quality, I have classed it as a family heirloom. Temperature loss very slow, even the lid appears to be double skinned. May have to adjust your starting temperatures. I rely on it to combat low air temperatures though I would think it could work in reverse by controlling high ambient air temperatures. The valve system appears very good, still to try them out. I vote it a hit.

    Next level beer

    Just what I needed to get my beer under complete control

    Conical fermenter with cooler pump and pressure transfer

    Excellent delivery time frame by DK. Unfortunately the fermenter had a deformed handle and it was not assembled properly so it sat askew in the base and wobbled on its legs. Emails to DK who contacted GF got what was a manufacturing fault quickly sorted with a bit of effort on my part using a screwdriver Have done one LME kit brew to start with and all went very well. The cooler worked brilliantly to keep a steady temp in summer and the pressure transfer unit also worked well. So a little disappointed with QA at the factory level but now everthing seems to be on track. Mike

    great bit of gear

    great bit of gear well thought out and best of all easy all round.
