at least a week, but mine just keeps better and better so i wouldn't worry about steeping it too long, i don't think thats possible until the nic degrades.
EDIT....i doubt it will last long enough for that to be a problem
Thanks Phorbin,
Just tried it out of the box and well....I don't know. It's also alot thicker than most of the other stuff. I'll put it in the closet for a while. Right next to the Casablanca.
