Storing citrus zest: freeze or dry? (and for how long?)

[Michelly]

I have a lime tree and a lemon tree. Periodically, I will get a pretty large number of either fruit, so it's pies, ades, cakes, and..ahem..margaritas. I also give many away.
But that's the juice (which I know can be frozen). What about the zest? Should I freeze it or dry it, and for how long?

I can tell you zest wrapped in plastic wrap and store in the fridge will dry out. That's not such a bad thing depending on how you want to use it. If you want to retain the original texture and taste I would freeze

I haven't experimented with drying zest, but I know you can freeze orange zest.
I just used some this week that I had frozen this past summer. The aroma was almost as strong, I think, as if it had been freshly grated.

How do you package your zest for freezing? I have not had good luck with the process myself and would like to know how to do it successfully.

I just put the shavings in aluminum foil, then into a plastic Ziplock-type bag. Stored in the holder on the freezer door (temperature about minus 2ºF).
Not sure whether aluminum foil would interact with more acidic zests.
Btw, I use fine shavings from a zester, not thick shavings from a peeler.
