The Grainfather all in one brewing system revolutionized all grain brewing at home. The Grainfather Conical Fermenter takes this one step further by giving you state of the art temperature controlled fermentation, just like commercial breweries use. 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 minimized. The Grainfather Conical Fermenter provides you with a modular system for all of this and more.


  • Modular system, upgrades such as the Dual Valve Tap, Temperature Controller
  • Glycol Chiller Also available for pre order
  • Superior temperature control
  • Double walled insulation
  • Integrated heating
  • Integrated cooling sleeve
  • Easy access to the interior for hassle free cleaning

DOUBLE WALLED: A double walled skin filled with a thick layer of polyurethane foam for insulation. This is what keeps the wort at a constant stable temperature that does not get influenced by any outside environmental changes and provides insulation for your fermentation that a standard jacket cannot achieve.

Integrated 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 liquid, this heat stick 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 dialed into the Temperature Controller and as the cooling liquid travels through this sleeve, it cools the stainless steel which in turn cools the beer in the fermenter. The cooling sleeve never comes into contact with the beer,it is completely concealed and built into the fermenter and never needs cleaning
