All-Jersey® and Queen of Quality™ marks are placed only on products made from 100% Jersey milk. The Jersey is a breed of dairy cattle that naturally produces milk with higher concentrations of protein and calcium than average milk. More protein and calcium not only boosts the nutrition of Jersey products, it also adds a richer taste, even to skim milk. When you purchase products with All-Jersey® and Queen of Quality™ marks, you are assured they come from the finest quality milk naturally produced by Jersey cattle.
