Thalassian Wine

Thalassian Wine is a type of white-wine sold throughout the lands of Azeroth (and possibly Outland). It is considered one of the harder wines to get hands on, though normally one may track down a bottle in Dalaran.

Hence the name, Thalassian Wine was originally produced in Silvermoon City, favored by the High Elven populace, though now it is primarily the Blood Elven people that drink this wine in Silvermoon. The wine is also drank by other races of the world, though the High Elves were known to make it in the first place.
