2 reviews for Grainfather G40 Brewing System – UK Model

  1. Aaron Hyde

    Quite possibly the best electric brewing system on the market when considering price, quality, features, and ease of use.

  2. Simon Dewfall (verified owner)

    Recently purchased as an upgrade to the g30. I wanted to brew less often. First impressions are really good. Great build quality and love not having the top plate and centre pipe. It takes longer to get to temperature (I guess what do you expect!) but so much easier to brew and clean and getting 2 19 litre batches from one brew day is fantastic!
