Product details

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.

Allow 1-3 weeks for delivery, The Grainfather ships directly from the manufacturer via Ups Ground. Express shipping options are not available.

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.

Warranty: 3-year faults and defects

Another Fantastic Grainfather Machine

After 200 brews in my G30, Santa gave me an upgrade to a G40. After 5 brews, the G40 is absolutely solid as expected. I like the new controller, the new wort flow design, and running at 220 volts. It's right at home with the rest of my GF gear - 4 conical fermenters, glycol chiller, and sparge water heater.

Big Step up from G30

The Grainfather team has learned a lot from the first G30 design, and it shows here in the G40. Overall, I'm a huge fan. You won't find anything below that's more prescient than David Heath's video review.

Better
- Fewer moving parts for setup and cleanup (no more silicone rings in the mash cylinder)
- Heating times much faster due to 220V.
- Sight glass
- Ending of top mash plate and ability to stir during mashing will up your efficiency

Worse than G30
- I noticed that the pump is more prone to seize with an air bubble in it than the G30 pump.
- When cooling, stir or be skeptical of the temperature controller. It'll get a current of cooled wort, and you think you're ready to condense into a fermenter. Likely no. Stir that thing multiple times because the temp controller is going to jump (it's trying to cool 10 gal of wort) and that temp gauge gets fooled easily (because the recirculation silicone is pouring anywhere into the hot wort. Your first brew or two (if you don't have an inline therm) is likely to be at ~100F in your fermenter if you're not careful. A glycol chiller can bring it in over time, but this was a learning curve (since i just knew if i chilled the wort in my G30 to ~160F before xferring into my fermenter, i'd have it at ~70F. Without dialing down the pump valve (to constrain flow), I'm only dropping ~40-50F on each circulation pass instead of the ~60-70F with the G30. That's a function of a stronger pump and probably a slightly wider set of tubing (haven't measured).

Things I'd have liked different or caveats:
- Standard drain valve on back. Yes, I can put one on, but for the price, I shouldn't have to.
- This will brew 10g of a standard ale/lager, but not of a high SG Belgian or Stout due to grain bill. Know that going in. I can fill a 5g Cornelius from a G30 batch that ends at 10-12% ABV, depending on the recipe. I cannot fill 2 of them in a G40.
- For brews nearing the grain bill limit, the holes in the grain basket for lifting will allow grain/husks to escape if you're not watching (due to no top plate holding them in). I would have liked mesh inserts that could serve as overflow for wort but not escape for the husks, that you popped out for sparging (lifting the basket). Don't want those husks bittering the beer as it approaches boil while sparging. Yes, it's answerable with an additional top plate or scaling down size (or a lil MacGuyvering), but the appeal of the G40 is to have 2 G30 brew days in one session.
- If you're going to make Pale Ales or IPAs, invest in a wide hop spider basket ($80 on Amazon). Much like the G30, the pump here struggles to pull through the hop filter. The G40 is wider than the G30, not taller, so you can get a 250 or 300 micron filter that's 12" wide and provide plenty of circulation during the boil. I had it seize on a 10g batch with 8oz of hops, which isn't that much...so wide hop basket from now on it is.

However, all of these are minor things, and it's a huge step up from the G30. Last, rethink whatever your ventilation/exhaust is in your current setup. The boil off is rate is considerably stronger (intentional), and the exhaust methods you had before if brewing indoors may be insufficient.

All I could have hoped for

Bought this moving up from the G30. Way more power in the pump and the heating element make brew day move faster. Grainfather has also made some engineering changes here (losing the silicone rings, top plate, better recirculating pipe logistics, sight glass) that contribute to strong ease of use. The only limitation I see here in the US is the need for 220 wiring, but it was well worth the investment for me.

I like that you can brew with one piece of equipment save time brewing and clean up.
