OK I may be called crazy, and it won't be the first time but hear me out please.
I am wondering if anyone has tried what I am about to suggest and if so what were the results?
Could one reduce the cost of hops by taking the whole hops(not pellets) used for Aroma in batch A (in a hop bag or in the hop back), and use them for bittering in brew B.
As if boiled for 60 min they would lose all their aroma, so letting that go into the first brew is not an issue. And, being only in the boil A for ~5 min, would only isomerise and extract about 12% of the potential IBUs. Which means I would be wasting the other 80% I could realistically extract (allowing for~8% I will never get out).
it is just that often I am adding 14% AA hops to get their lovely aroma and then chucking them, which seems like a huge waste if I could have bittered a second batch with them. Especially given how much energy and water are required to grow hops in the first place.
