The Jameson Crested derives from the classic Crested Ten, which was renamed in 2016. The word "Ten" has been removed from its name, as it was not a 10-year-old whiskey, and has been replaced with an X. Jameson Crested is a complex blend of aged whiskeys and is a testament to the Jameson tradition of quality established in 1780. Crafted by the master blender, each whiskey is carefully chosen for its particular character and skilfully married together. A fuller, richer, spicy, "sherried" version of the regular Jameson with the majority of the blend being 7-8 years with approximately 60% of the blend being pot still and 40% grain.
