Bushmills sherry cask is aged for a minimum of 10 years. This aging process takes place in ex-bourbon barrels, which imparts certain characteristics to the whiskey. The use of ex-bourbon barrels adds a layer of complexity and depth to the flavor profile of the whiskey, as it allows for the transfer of flavors and aromas from the previous spirit that was aged in the barrel.
After the initial aging in ex-bourbon barrels, the whiskey is then finished in Oloroso Sherry casks. This finishing process involves transferring the whiskey into these sherry casks for a period of time, allowing it to further develop and enhance its flavor profile. The use of Oloroso Sherry casks adds a distinct richness and complexity to the whiskey, as it imparts notes of dried fruits, nuts, and spices.
The choice to finish the whiskey in Oloroso Sherry casks is a deliberate one, as it adds a unique and desirable flavor profile to the final product. The sherry casks provide a depth of flavor and a smoothness that complements the existing characteristics of the whiskey, resulting in a well-balanced and enjoyable drinking experience.
