When we went to Montalcino, the local bars would ask us what we wanted opened next after one of the bottles ran out. they had about 3 or 4 brunello open at a time. the "castle" must have had 50 or so open, and would provide a tasting of each distinct micro area of brunello. i could not tell the difference.

in bologna, there enoteca Marsalla will have about 15 premium reds from pretty much everywhere in italy open for by the glass. when you drink the number of open bottles down to 10, they will open anything you request(from italy).
