Yeah, I didn't know WTF it was either!
Read a story in the local weekly paper about one opening here by the end of the month. Apparently, they offer gourmet culinary condiments, fruit vinegars, exquisite oils, selected wines, exotic liqueurs and fine and rare spirits, all sold straight from the cask. They also allow you to sample anything before you buy it.
Has anyone been to one of these? Can I really buy some bourbon/scotch/rum "straight from the cask" or do they empty a bunch of bottles into their own casks, as I suspect? How many "samples" am I allowed?!
