The Chivas Brothers’ Blend each has its own unique formula and selection of many aged whiskies, giving them their own distinct character, flavor and taste experience. For whisky to legally become Scotch, the new spirit must be matured for a minimum of three years in oak casks. For Chivas Regal, all the casks of whisky selected have been carefully matured for at least twelve years. It is the skill of the Master Blender to select the many different casks of malt and grain whiskies, all at the correct age, harmonizing the characters and flavors to ensure the superlative quality and consistent taste experience of Chivas Regal year after year.
