not really that hard, believe it or not. I make my IPA around 6 times per year (2-3 batches are for parties/club functions) - 15oz of hops per batch thats almost 6 pounds right there. I make my father in law's beer for him 4-5 times a year, at 7oz a batch, theres another 2.
That's only my two most frequently made recipes, if you figure I make 15-18 batches total a year, so lets say another 8 batches at an average of 5oz per batch, well there you go, that's 165 ounces.
