Abstract
Ice for use in a beverage, wherein the ice comprises a core, an active zone, an external surface, and caffeine. The ice particle has a depth from each point of the external surface extending perpendicularly inwards. It also has a total particle mass. The caffeine in the ice particle has a total caffeine mass, and the ice particle has an ice caffeine concentration equal to the total caffeine mass divided by the total particle mass. The active zone includes at least 40% of the total caffeine mass and local caffeine concentrations of at least 150% of the ice caffeine concentration. At least 67% of the total caffeine mass is contained within a caffeine depth in millimeters from the external surface no greater than 1.06 times the cube root of the total particle mass in grams. The core has local caffeine concentrations of less than 150% of the ice caffeine concentration.
