A skill can gain up to 40% affecting the minimum score roll of a drink recipe. Skills affect manufacturer/characteristics and the AVERAGE skill of all the characteristics of the product is used. If for instance you have Goose Island Beer at 2%, Goose Island Ale at 1% and Pale Ale at 0%, the average would be 1%.
