Grainfather

The Grainfather is an all-in-one electric all-grain brewing system: you mash, sparge and boil in one stainless steel unit, and the counterflow chiller cools the wort. The G30v3 makes up to 40 pints (30L capacity) and the G40 makes up to 40L per brew. Both connect to the Grainfather app for step-by-step brewing. We also stock Grainfather fermenters, sparge water heaters, grain mills, chillers and spare parts.

Buying guide & FAQs

G30v3 or G40: which Grainfather should I buy?

The Grainfather G30v3 with counterflow chiller has a 30L capacity and makes up to 40 pints per brew. It is the natural choice if you're moving up from kits or extract brewing. A version without the chiller is available if you already have one. The Grainfather G40 brews up to 40L per batch. It has larger surface-mounted heating elements and a wireless smart controller, so it suits brewers who want bigger batches. Both are made of 304-grade stainless steel and link to the Grainfather app for recipes and step-by-step control.

Fermenting the Grainfather way

The GF30 Conical Fermenter has a built-in wireless controller, a dual-function valve for dumping yeast and taking samples, and a 60° cone for clearer beer. A Basic Cooling Edition is also available. For bigger batches, the SF50 Conical Fermenter holds up to 45L of wort.

Frequently Asked Questions
What is a Grainfather?

How much beer does the Grainfather G30 make?

The G30v3 has a 30L capacity and makes up to 40 pints of beer per brew.

What's the difference between the Grainfather G30 and G40?

The G40 brews larger batches, up to 40L, and has a wireless smart controller and larger surface-mounted heating elements. The G30v3 makes up to 40 pints and suits most home brewers.

Do I need a separate fermenter with a Grainfather?

Yes. The Grainfather makes the wort, and you then ferment it in a separate vessel. The GF30 Conical Fermenter is designed to pair with it, but any suitable fermenter works.

How do I clean a Grainfather?

After brewing, circulate Grainfather High Performance Cleaner through the unit and the counterflow chiller as directed, then rinse. It removes protein deposits without scrubbing and is safe on copper and stainless steel.
