Wow. You really jumped in! Most of the
juice should be good for at least a year if you keep them in a cool, dark place. You don't happen to have a wine cellar, do you?

Honestly, shake them all up really well, open them up and give them a smell. The ones you are most hopeful of, taste test them right away. If they are not all that you had hoped for, let them steep. I would say, try as many of them as you can, as soon as you can. If you don't have a dripping atomizer for testing, you might want to get one. Honestly, a big chunk will probably turn out to be losers. As far as the winners, as I said, keep them in a cool, dry, dark place. Opinions are mixed, but I would say if you have a large quantity of juice that you really like, you might consider storing it in the refrigerator or even in the freezer.
