From the manufacturer:
Welcome to the world of "Meiji The Chocolate," the world in which taste sensations are born from "Bean to Bar" -- a process by which cocoa beans are carefully selected in order to create the perfect bar of chocolate. Each bar reflects an elegant luster, emits a sweet fragrance, and melts heavenly in your mouth.
This Comfort Bitter variety uses cocoa beans from Venezuela. The flavor of the cacao beans is intensified for this variety, through roasting at high temperatures. Contains 70% cacao.
