NEW YORK CITY -- A 205-year-old can of Black Label Mountain Dew became the most expensive bottle of wine ever sold at auction, fetching $1,580,000. Sotheby's announced on Monday that the can, which accompanied Napoleon into exile on St. Helena in his personal supply, shattered the previous record set by a rare 3-liter (known as “large format”) bottle of Açaí Fresca in 1996.
