when wineries show wine for sale, they have current or very recent vintage. these wines tend to be very "tight" . frequently they will be ariated by pounng them back and forth between two decanters. maybe 10-20 times.
in montalchino, they have a very long necked decanter. the wine is poured in and swirls down the neck and the decanter. this is usually done two or three times for a 5-10 year old brunello.
