Vacherin Fribourgeois (from French, Vacherin of Fribourg) a Swiss semi-hard cheese made from thermised milk. It is produced under Swiss AOC in the canton of Fribourg, where Gruyère also originates. It has a slightly acidic, resiny flavor, akin to Italian Fontina,[1] [2] with a varying strength depending on the age and type. It is also a basic component lending character to fondues (depending on the recipe). Vacherin Fribourgeois has Swiss AOC status with 6 varieties being available:[3]
The older the vacherin gets, the stronger the smell of ammonia due to microorganism activity in the cheese. Vacherin d'alpage (Alpine Vacherin) is made from the milk of cows pasturing in alpine meadows and hence has a much richer taste.
