I have a recipe that I will be brewing this morning. The recipe calls for Hallertau Pellets 4.5% alpha acids. When I went to the local home brew shop they only had Hallertau 4.2% Alpha acid.
My question is how do I do the math to figure out how to add more/less hops to my brew? Thanks for the help.
