If your talking about fresh compared to dry then no, not 1:1. If your talking about fresh bunch herb Vs the fresh in the small plastic pagages there is no difference assuming the stuff in the package is still fresh. Store bought dry Rosemary can be pretty anemic. If you buy a large fresh bunch and have left overs put it in a brown paper bag and leave it in the crisper drawer of your fridge until it dries out. It will stay green and still be a heckuva lot better than the store bought dry herbs. Once dry it will come right off the branch and you can bottle it up. It will also last a coons age.
BTW Merry Chistmas.
