Brewing efficiency is the amount of fermentable material you get from the grain, this is based on a theoretical of 100%, and I normal have it around 70%. From this I can calculate the gravity, but my gravity went up this time and from this I could back calculated that my efficient had increased. But these increases will reduce the extraction of hop acid, so you generally increase the hops to compensate this
