Balvenie is not owned by Glenfiddich. Although both distilleries are located in Dufftown, Scotland and have a shared history, they are actually owned by separate companies.
Although Balvenie and Glenfiddich are owned by the same company, they maintain their own unique identities and production processes. Each distillery has its own set of stills, warehouses, and production methods, which contribute to the distinct characteristics of their respective whiskies.
Personally, as a sommelier and brewer, I have had the opportunity to taste and appreciate the whiskies produced by both Balvenie and Glenfiddich. While they share some similarities due to their geographic proximity and shared ownership, they also have their own distinct flavors, aromas, and profiles. It is always fascinating to explore the nuances and complexities of different whiskies, and both Balvenie and Glenfiddich offer their own unique experiences for whisky enthusiasts.
