Introducing the new G40 from Grainfather, packed with all of the innovative features you can find in the G70 plus more

The Grainfather G40 is the 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 easily create your own.
