The Grainfather G70 (70 Liter)
70L of innovation, consistency, and power has helped to create one of our most compelling systems to date. The inherent strength and safety capabilities of the G70 are matched by its bold, contemporary look and new smart brewing technologies.
From the creators of the original award-winning all-grain brewing system, the Grainfather G70 represents the next level in brewing equipment. We’ve stepped up our game to bring you a smarter brewing system with a larger 70L capacity, improved design, wireless control, app integration, and the same Grainfather signature quality guarantee.
Whether you're a homebrewer looking to raise the stakes or a commercial brewery looking to bring authenticity back to your pilot batches, the G70 is your true brewing companion. It gives you everything you need in one compact package that can be used virtually anywhere.
- Two-stage false bottom. The conical base allows a false bottom with an inner collar to sit in the recess of the base. Early testers used 600gs of hops and saw full flow through the pump. This is very effective.
- 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.
- An 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.
- The 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 recirculation. 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 setup. There are 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.
- Glass lid with 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.
- A 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.
