Like many Irish whiskeys Jameson is triple distilled, compared to the typical 2x distilled of Scotland and America, which removes more “impurities” and gives it more of a light clean flavor. Think of how vodka brands hype their 6, 7, 8, etc, distillations to achieve an even cleaner and lighter spirit. Jameson is also a blended Irish which means the 3x distilled malt whiskey is blended with grain whiskey which lightens the flavor and texture even more.
From the rich countryside of Ireland came nature's finest barley and crystal clear water. These natural ingredients are carefully distilled 3 times, to create the natural, smooth whiskey that is "Jameson".
