    Why Buy From Happy Hops Home Brewing
    The Grainfather GF30 Conical Fermenter has built-in wireless control, so you can control and monitor fermentation from anywhere! 

    The GF30 Conical Fermenter gives brewers more flexibility and freedom during fermentation than ever before! Connect the built-in wireless controller to the internet and the Grainfather App, add fermentation tracking devices and control/monitor fermentation from anywhere!  

    The GF30 Conical Fermenter allows you to dump yeast, take samples and transfer your wort via our innovative, dual function, valve design. Partner it with the Grainfather GC4 Glycol Chiller  and get full control over the heating and cooling of your unit.


    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 that 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 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 - 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 minimizes 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.
