The Grainfather G40 is the latest brewing system in the G Series ranges from Grainfather. Packed with all of the innovative features you can find in the G70, this brewing system is your new best friend for brews up to 11 Gal (40L), perfect to fill two 5 gal (19L) corny kegs. The Grainfather G40 brewing system has a bigger capacity and better connectivity. With a pre-boil volume of up to 12 Gal (45L) and mash volume up to 11 Gal (40L) easily produce up to 11 Gal (40L) of beer from one brew. Connect your mobile device to the smart controller with built-in wireless control via the Grainfather App, for step-by-step brewing and access to bazillions of recipes.

10 gallons (40L) too much? G40 is the 5-gallon (19L) brewers' new best friend! Ideal for 5-gallon (19L) batches, with options of a traditional mash and sparge or no sparge. Think of no sparge like an awesome computer-controlled stainless steel BIAB system. The powerful 3300w heating element will ensure quick heating times and shorter brew days. Push the upper limits of high gravity brews with the increased grain basket size.

Manage your brew remotely with step-by-step brewing with the smart wireless controller. All you need to do is connect your mobile device to the controller and control your brew through the FREE Grainfather app where you have access to bazillions of recipes to choose from or create your own! Pair with Grainfather Conical Fermenter and Grainfather Glycol Chiller for the ultimate brewery.

G40 Features:

  • 304 Stainless Steel. G40 body built with sleek 304-grade stainless steel.
  • Wireless brew session control. Connect your mobile device to the smart wireless controller via the Grainfather App and WiFi to manage your brew remotely. The Grainfather app gives you access to brewing tools and calculators to brew with confidence, and bazillions of recipes to choose from or create your own.
  • PID heating control for accurate temperature management during mashing.
  • Concealed conical heating element. Large, surface mounted 3300 W heating elements heat wort evenly and quickly. The element covers 80% of the base and it's mounted using thermal paste rather than braised. This increases heat efficiently, by minimizing heat loss in areas it’s not needed. The wide heating area minimizes hot spots and scorching. Most solids settle on the false bottom, not the elements, making clean-up a breeze.
  • Conical Base. Reach your expected gravity with a conical base for maximum wort transfer.
  • Counterflow wort chiller for a more efficient and sanitary brew transfer.
  • CIP. Quick and easy cleaning with CIP (clean in place) capability.
  • Integrated sight glass for easy volume readings. Instead of trying to judge the level of your pre-boil, you can now sparge until you reach pre-boil volume. It’s also easy to clean.
  • New rolled edge mash plate. No more silicone seals, the plate has a smooth finish, making it more robust, hard-wearing, and easy to install. Compared to the G30, the G40 is wider, but not much taller. Comparatively, draining is quick from the basket and there’s less likelihood of a stuck sparge as the draining surface is bigger.
  • New rolled edge hop filter to reduce blockage. Paired with the conical bottom leaving only trub and hops behind, results in only clear wort going into the fermentor.
  • Lifting bar included with winch lifting hook. Use the bar for a two-person lift or use a winch system for individual brewers.
