Bespoke 3.2 kWh concealed conical heating element. Make the most of the power available. The element covers around 80% of the base and is mounted using a thermal paste rather than braised. This moves the heat efficiently upwards, minimizing the loss of heat to areas where it’s not needed. As it’s spread in a wide area, hot spots and scorching are very unlikely. Also, most solids settle on the false bottom, so they won’t touch the elements. As it’s concealed, it makes cleaning easy too.
Integrated sight glass for easy volume readings during sparging. Instead of trying to judge the level of your pre-boil, you can easily sparge until you reach pre-boil volume. It’s also easy to clean after every brew. The sight glass cap can be replaced with the sight glass cleaning barb to easily recirculate a cleaning solution.
- Bottom drain below the false bottom means minimal dead space.
High temperature, high flow rate, food-grade pump. With an 8L per minute flow rate, you can transfer your brew efficiently and safely.
- Heavy duty handles on the outside of the G70 unit.
Convenient side entry re-circulation. Rather than up and over, the G70 has a built in port on the side of the unit. If the pump is accidentally switched on, the wort will be safely directed back into the boiler.
New rolled edge, mash plates and hop filter for increased strength and easy set up. There’s no more silicone seals, as the plates now have a smooth finish, making them more robust, hard-wearing and easy to install. Compared to the G30, the G70 is wider but not that much taller. Comparatively, the draining is still quick from the basket and there’s less likelihood of stuck sparges as the draining surface area is bigger.
Safety aspects including locked in support ring, heavy duty, no slip brackets on the grain basket and protection from knocking the ball valve open.
Automatic heat sensors and safety cut-out for dry boil protection.
Color LCD controller screen with magnetic mounting for easy viewing from all angles and manual control. Included is the glass lid with a handle.
Ball valve for sampling/draining: This runs in line with the pump so it’s particularly helpful when draining the cleaning water. The water runs out quickly, emptying the unit in no time.
Huge Wort Chiller included. Despite the volume being more than double, cooling times remain around the same as the G30 thanks to a more powerful pump, efficient false bottom and bigger wort chiller to match the wider unit. The large size means it needs to be positioned away from the G70, however this is made easy with longer silicone tubing attached as standard.
Lifting bar included with winch lifting hook. Use the bar for a two person lift or with a stable winch system for individual brewers to lift the grain basket.
Large dual-stage hop filter provides a large surface area to allow for a hopping rate of up to 1.5kg, which also reduces pump load and blockages. Robust stainless steel body and excellent build quality.

It would be great to hear from anyone who is using the GrainFather G70 or the G30 and get some first hand tips and tricks using this amazing equipment.
