My brother (a Mormon) was sent to help with Hurricane Andrew. He went to a member's house (or what remained of it) and was a little appalled to see piles of crushed Bud cans outside the guy's house. Turns out that when the hurricane hit, they turned off the beer and start canning tap water; they don't bother to clean out the new, unfilled beer cans. They put lables on the cases and ship them that way.
And they do this for free! I understand that Coors does the same thing. They also pay for the shipping: they'll load several semi trailers full of water and ship them where they're needed. Sounds like they are good corporate neighbors at time of crisis.
Water is water; it'll keep you alive, and, after breathable air and (arguably) shelter, is the most important item to consider after a disaster. And, believe me, when you've been working in a hot, humid climate (like Florida, post-Andrew), even crappy-tasting water can be a blessing.
