According to my schoolboy maths, if a recipe calls for a specific weight of hops at a specified AA%, then if the hops available are at a lower AA% then you simply multiply to make up the difference. Eg - the recipe I brewed yesterday called for 32g of hops at 4.5%AA; mine were rated at 3.0%AA so I should have added 48g (ie 1.5 x the original weight). Is that right or am I over-simplifying it?

The resulting wort tasted spot on, but I was wondering if I managed this through luck rather than judgement! :confused:
