So I want to brew some all-grain recipes from "Brew Like a Monk." However, I am confused how to do so with their recipes as they do not give weights of the ingredients. Rather they give percentage of each ingredient and target OG and FG. Does this mean I have to have a program (ie promash) and plug the numbers in? Are there are any free web based calculators to do so (I have an apple and promash not compatible with)?
Thanks
