Storing unused film

[SourChipmunk]

A quick question, I hope. I bought way too much film for a wedding I shot. I have no idea when I'll next get around to using a film camera. So, what is the best way to store unused 35mm rolls and how long can they last?

Excellent. They've been in the fridge in the original plastic containers for more than a year now. I wonder what kind of shelf life they'll have that way.

Thanks!
