Grainfather G70 Features

High Performance

This brewer uses up to 3300 watts at high temperatures and offers a high flow rate through a food-grade pump. It pumps out 2 gallons or 8 liters of brew per minute. This means transferring the brew is efficient and safe.

Overall, it’s a large brewer that can produce 16 gallons or 60 liters of wort at a time.


In my Grainfather G70 review, I find that the product stands up proudly to the tradition of Grainfather’s innovation and consistency. The brewer is made of stainless steel and has a strong and contemporary look.

Grainfather G70 brewing system is fitted with an integrated sight glass that allows you to read the volume as you go sparging. This means you don’t need to stop sparging and check the volume or judge things blindly. Rather, you can continue with the process and keep checking the volume through the sight glass until you get the pre-boil volume.

You can replace the sight glass cap with a cleaning barb to clean the sight glass after every brew.

Smart Brewing

Grainfather G70 offers to take your brewing to the next level. With wireless control and iPhone and Android app integration features, it turns out to be one of the smartest products in its category. Get ready for a remote-controlled brewing experience. To that end, it supports both Apple and Android devices.

Concealed Heating Elements

The brewer is powered by a 3.2 kWh conical heating element. The bespoke heating system is secured on the base and is fully concealed making it easy to clean. The heat moves up the vessel avoiding areas that do not need heating. This way, the Grainfather G70 electric brewing system is a lot more energy-efficient than many of its competitors.

Since the heat spreads over the wide area of the brewer, there is little possibility of developing hot spots. The solids from the grains settle down on the false bottom and the heating elements are securely away from the content in the brewer.
