Question

Rarely, the vintage date on a bottle of wine is not the same as the harvest year, but is the calendar year before the harvest year. for which wine on the list below is this most likely to be the case?

Answer 1

Ice Wines

Ice wines are a type of dessert wine with a characteristic sweet taste. They are made from grapes that have been frozen (i.e. by frost) while still on the vine, and are thus mostly produced in countries in which favorably cold temperatures at certain times of the year can be attained with regularity. These countries include Germany and Canada. 

Since the grapes are frozen on the vine, only the water freezes, and not the sugars and other dissolved solids. This produces only smaller amounts of wine which is more concentrated and very sweet. However, the sweetness is balanced by its high acidity, making it refreshingly sweet.
