Why Use a Graincoat?
Heat loss during the mash can cause temperature drops that affect efficiency and consistency. The Graincoat minimises this by insulating the boiler, reducing the need for the heating element to compensate — saving energy and giving you more stable, repeatable results. Particularly valuable in garages, sheds, or outdoor brew setups where ambient temperatures vary.
This is an official Grainfather accessory designed for the G30. Not compatible with other Grainfather models.
