I broke a toe just a week before my departure date so I had to reschedule my Colorado Trail thruhike for next year. I'd already purchased the food for my mail drops and I'm trying to figure out what I can save for next year. I have several large unopened cans of Nido, they all have April 2013 as the expiration date which I assume is a conservative estimate designed to cover the company's behind in legal matters. Would they still be safe to use next summer? Would it help to keep them refrigerated until then? What about things like protein bars, will they be edible in a year?
