Not soft drinks, not beer. Chocolate milk. That statistic is the shortest possible explanation of Cocio, which has been sold at the country's polsevogne since 1953 and has occupied the space next to a sausage in Danish street food ever since. The recipe has not changed since 1951: milk, sugar, cocoa, and the particular processing that lets a bottle of milk sit on an unrefrigerated shelf without spoiling.

A rival brand called Congo held about a quarter of the Danish chocolate milk market, and the two competed until 1989, when Cocio bought it.
