Default Whole leaf hop question

Could I replace 1oz of a pellet hop (Simcoe) with 1oz of whole leaf and get the same AA? Or is there a formula for substitution? The Hops are being planned to be added at 15 and flame out.

Usage is 1oz pellets to 1oz loose - and the alphas should be noted somewhere on the package - they vary from crop to crop.

the AA would be the same across a different amount of hops but the IBU's contributed from whole leaf vs pellets is different. you need more whole leaf than pellets. i think the utilization of whole leafs is something like 75% that of pellets. im sure someone will chime in with a more reliable number.

my info comes from the guys at the HBS...though many on this forum say that extraction is slightly lower when using loose hops

It is. But for 15 minute and aroma hops, the IBU differences would be negligible.

Would food processing whole hops help?

I meant IBU, had to deal with a flooded basement so the brain isnt working today.

10% is the rule of thumb. Agree it doesn't really matter for late additions.
