There are more than 50 varieties of red and white grapes grown on the small volcanic island, but the most prominent and famous is the Assyrtiko.  Combined with the soil and climate, it produces excellent, complex whites with hints of honey and green apple
Additionally, Santorini is known for its delicious Vinsanto wine, made from late-harvest sun-dried white grapes.  This full-bodied dessert wine is aged at least two years in oak, and brings rich flavors of dried fruits, plums, caramel, hazelnuts, and tropical fruit.
