This is the first time that Willett has released an Exploratory Cask Finish which is commonly referred to as XCF 1.0. For the first release, a 7 year-old American Rye Whiskey was finished in Curacao Casks, which were sourced from France, for approximately 90 days. Curacao Casks are used to make Curacao which is a liqueur flavored with the dried peel of the laraha citrus fruit grown on the island of Curacao. Because these barrels were imported from France an unconfirmed rumor is that they were previously used in the production of Grand Marnier. The rye used was most likely sourced from MGP in Indiana and aged and finished at the Willett property in Bardstown, Kentucky. 6,912 Bottles were produced.
