Which Greek wine region is famous for the sweet wine vinsanto?

D.

Santorini is a volcanic island south of Athens that is famous for vinsanto, a sweet dessert wine reminiscent of the Tuscan dessert wine vin santo. To make vinsanto, the white grape assyrtiko and the red grape mandilaria are first spread out on mats to dry in the sun for one to two weeks. When they achieve a state referred to as half-baked, the grapes are fermented. Afterward, the wine is aged in barrel for a decade, giving it a mellow, rich flavor.
