How long is a box of Joe Good For?
If it's refrigerated, it'll last for at least a week, as long as you didn't pre-dairy it. Unrefrigerated, I wouldn't trust it for more than a day. Coffee is a crappy growth medium and it should start out the next best thing to sterile, but, even covered, its going to start to get moldy.
