Do you adjust dry hopping substitutes for AA levels?

[daveotero]

Just brewed a batch last night that calls for dry hopping with 1oz of Centennial (10.0%) and 1oz of Crystal (3.5%). I couldn't get crystal at the LHBS so I'm substituting with Mt. Hood (5.5%).

I plan on just tossing the whole ounce in, but I was wondering if anyone ever adjusts for alpha acid levels for dry hopping? What if the difference was larger? Do the AA levels correlate to the aromatic proprieties at all?

Alpha acids won't matter. The oils are what provide the aroma in a dry hopping situation. Just use a balance of whatever you would like. It'll be fine.

In order for the alpha acids in hops to isomerize and actually bitter the wort, you have to boil them. You are really only adding hop aroma in dry hopping...and maybe a tiny bit of favor, but no bitterness.
