The Grainfather is your all in one brewing system to make beer from grain. The sleek look, user friendly and intuitive design, and innovative features, make this the perfect brewing companion for both beginner and experienced all grain brewers.

It is made from high quality, 304 grade stainless steel. It has a 30 L capacity, which is designed to make up to 23 L of beer from one brew.



The Grainfather is electrically powered and designed to be used indoors. No need for burners, or hot plates, just plug in and go! It is fitted with a controlled heating element, which ensures the correct power is used during different stages of the brewing process. A gentler heat is used during certain stages for accurate temperature control and to minimise the risk of scorching. During stages that require more vigorous heating, it can take as little as 20 minutes to reach boiling point.

Control Box for Heat & Power Control

For the ultimate brewing experience, use the Connect Control Box in conjunction with the Grainfather Community App. The control box has Bluetooth connection and so your mobile device can be used to control your unit remotely. This allows you to multitask or simply relax while brewing. The app will notify you when you reach the next stage of your brewing process.

For maximum brewing efficiencies, a 6 Watt, 1,800 RPM magnetic powered pump has been fitted to recirculate the wort through the grain bed. This pump is also used during the cooling stage to push hot wort through the wort chiller. Additionally, the pump makes the cleaning process quick and easy as cleaning detergent can flow through the pipe work. The magnetic drive pump has gone through rigorous testing against multiple pump styles to ensure it meets the tough demands of continuous brewing. The pump is concealed by a stainless cover, which easily pops open to give you direct access. A pump filter is fitted inside the Grainfather to prevent hops and stray grain from entering the pump or pipework, keeping the wort clear while also preventing any blockages.

Grain Basket 

A stainless steel, expandable grain basket allows you to brew from 4.5 to 9 kg of grain. The fitted perforated plates and telescopic pipework, make it easy to adjust the size of the grain basket to suit the size of the grain bill. For grain bills below 4.5 kg, you’ll need to fit the Micro Pipework (sold separately). When ready for sparging, a basket handle is inserted into the grain basket to lift it up and out of the wort. Once lifted, a 45 degree turn allows the grain basket’s feet to rest on the specially designed support. The grain basket is then able to drain while you batch sparge over the top. A Sparge Water Heater can also be purchased to heat your water to the specific temperature required.

Counter Flow Wort Chiller

This chiller has two connection points. One side is connected to the Grainfather, while the other is connected to the cold water tap. The hot wort is then pumped through a copper inner coil while the cold water is pumped through the outer pipework in the opposite direction. This provides the instant exchange of cooling and heating, and the cooled wort can then be pumped directly into your clean, sterile fermenter where the yeast is then added. This reduces the chance of contamination as nothing is inserted in the wort and it is only passing through the wort chiller at a single time. 23 L of wort can be cooled in as little as 20 minutes. The cooled wort temperature will be approximately 5 degrees above your tap water temperature.


The Grainfather is fully supported around the world by a fantastic support team who love brewing just as much as you do. Our support team is here for any technical enquiries on brewing or how the Grainfather works, as well as general customer service enquiries. All Grainfathers come with a 3 year warranty.

PLEASE NOTE: All Grainfathers contain a yellow packaging strip in the boiler. This should be discarded before you begin brewing.

    I’ve had the Grainfather since August 19 and it’s a genuine pleasure to use. Yes I have made sensible mod, like a cam-lock for the sparge arm, but that was for additional unnecessary convenience. I recommend checking out (In addition to the Malt Millers YouTube vids) The Beardy Man, Homebrew with Griffo and Gary James all on YouTube to see it being used in action and for hints and tips.

    Everything that comes with it is a real boost over kettle and cooler-tun brewing, recirculated mashes and the counterflow wort chiller are superb. I’ve since purchased additional add-ons, but that was to suit my specific need. My only niggle is that you can’t programme in gradual stepped mashes, but I’m sure that could be added on to the app if if was requested enough.

    I know some people have had issues with the app (I haven’t) but I’d always recommend a back up paper brew day sheet and you can manually control it if you need to. I love the delayed start for heating the mash water. All in all I love the G30 and would only replace it with the Brewtools 40 if I won the lottery!

    If purchasing I would recommend the Grainfather High performance cleaner AND the small batch pipework, as one is essential and the other will help ease you into it (like I wish I had).
