Gotlandsdricka
Gotlandsdricka (in modern Gutnish drikke or drikko, and drikku) is a traditional homebrewed alcoholic beverage made on the island of Gotland, Sweden. It is a kind of ale, closely related to the Finnish sahti, with a smoky, bitter-sweet, spicy ( juniper) flavor.
It is similar to an everyday drink used during the Viking Age in most Nordic countries. The tradition of brewing drikke has survived on Gotland, a process that was originally carried out exclusively by women.
Difficult to produce for commercial distribution, it has become a cultural marker for Gotlanders. An annual drikke brewing world championship is held in Gotland each autumn.
