coffee after shtf

I never used to drink much coffee, but going to work when it's dark and the bad influence of a coworker have gotten me into it. What are your plans and equipment for keeping the caffeinated black elixir of life a-flowin' during short term emergencies like a storm or power outage, or even...

I am thinking of making some buckets with a mix of items in them. I was thinking of putting coffee and tea in mylar bags with O2 obsorbers. Anyone know the shelf life would be?

How do I make coffee when camping/hiking/backpacking?
