The Grainfather G40 is our latest brewing system in the G SERIES range. Packed with all of the innovative features you can find in the G70 plus more, this system is your new best friend for brewing up to 38L of beer and filling 2 x 19L corny kegs. With a max grain bill of 13kg, you can adjust a high ABV recipe to a smaller batch volume, allowing you to brew larger grain bills that can easily go above 9% ABV.

Just like the G70, you can manage your brew remotely with the smart controller that has built-in wireless connectivity. Simply connect your mobile device to the controller and manage your brew through the FREE Grainfather App. Once connected, you’ll have access to a step-by-step brewing system and thousands of recipes to choose from, or you can even create your own!


  • G40 body built out of high grade, 304 stainless steel
  • Heats wort evenly with conical shaped surface mounted heating element
  • Conical base for maximum wort transfer
  • Connect your mobile device to the smart controller with built-in wireless connectivity via the Grainfather App and manage your brew remotely. Our free brewing app has all the tools, calculators and recipes that empower you to create amazing beer at home. Or get creative and design your own with our feature-packed recipe creator!
  • Comes with a counterflow wort chiller for a more efficient and sanitary wort transfer
  • PID (proportional integral derivative) a specially developed algorithm for managing accurate and consistent mash temperatures
  • Quick and easy cleaning with CIP (clean in place) capability
  • Integrated sight glass for easy volume reading
  • Rolled edge grain plate and perforated basket for easy mashing
  • Large bottom mounted hop filter reduces pump and chiller blockages
  • NZ/AU ONLY: The G40 comes in 10amp mode, but you can choose to upgrade it to 15amp mode if you wish to add more power to your brew. The 15amp cable is sold separately and a 15amp socket needs to be professionally installed into your homebrewery.
  • We’re confident that our products will produce professional results, just like the craft breweries. That’s why every G40 comes with a 3-year warranty.
