Jameson Irish Whisky is launching their first ever cask strength whisky—the Jameson Bow Street 18 Years Cask Strength. Usually, whisky is brought down from its maturation level of alcohol-by-volume (abv), which is typically in the 60 to 65 percent range, to a less expensive 40 percent range by diluting it with water. Jameson’s cask strength whisky will be sold at 55.3 percent abv.
This new flagship whisky was distilled and matured in the Jameson Middleton Distillery, Co. Cork. The first maturation process was an 18-year maturation in bourbon and sherry casks. The whisky is then married—a traditional method of re-casking batches of vatted whisky and then re-warehousing it in order to ensure infusion. After marrying, the whisky is re-casked into first-fill ex-bourbon American oak barrels for an additional six to 12 months in the maturation house at the Jameson Distillery Bow Street—Dublin’s only live maturation house. This return to Bow Street marks the first such endeavor since 1975.
The Jameson Bow Street 18 Years Cask Strength whisky has deep toffee notes and spice, coupled with the flavor of oak, leather, and vanilla. A subtle sherry nuttiness rounds off the taste. The whisky will be available in 20 markets starting in July 2018.
