Glenfiddich IPA is aged for a total of 16 weeks. The aging process involves two distinct stages, each contributing to the unique flavors and characteristics of the final product.
Firstly, the American Oak casks used to age the IPA are loaned to Speyside brewer Seb Jones for a period of 4 weeks. During this time, the casks are filled with an IPA brewed using Challenger hops. This collaboration between Glenfiddich's malt master Brian Kinsman and Seb Jones allows the flavors of the IPA to infuse into the casks, imparting their own distinct characteristics.
After the IPA has been emptied from the casks, they are then used to finish non age stated Glenfiddich whisky for an additional 12 weeks. This secondary aging process takes advantage of the flavors and aromas left behind by the IPA, resulting in a whisky with a unique twist.
The total aging time of 16 weeks allows for a harmonious integration of the IPA flavors with the whisky, creating a balanced and complex spirit. The American Oak casks play a crucial role in this process, as they contribute their own vanilla and toffee notes, enhancing the overall flavor profile of the Glenfiddich IPA.
Personally, I find the concept of aging whisky in casks previously used for beer to be fascinating. It brings together two distinct worlds of beverage production and allows for the exploration of new flavor combinations. The collaboration between Glenfiddich and Seb Jones showcases the innovative spirit of the whisky industry, pushing boundaries and creating exciting new expressions for whisky enthusiasts to enjoy.
The Glenfiddich IPA is aged for a total of 16 weeks, with 4 weeks spent aging an IPA in American Oak casks, followed by an additional 12 weeks of finishing non age stated Glenfiddich whisky in the same casks. This unique aging process results in a whisky that showcases the flavors and characteristics of both the IPA and the casks themselves.
