Ultra pasteurized, pasture-raised organic milk contains all the fresh, wholesome goodness you expect from Organic Valley. All Organic Valley dairy farms are pasture-based, meaning the major portion of the cows diet comes from pasture. Since grazing is a bedrock principle of our organic farming system and philosophy, we long ago created a strict pasture policy, which we are proud to say was the model for a supplemental federal rule in the USDAs National Organic Standards. We believe that when cows eat well, you do too! Organic Valley pasture-raised milk is homogenized and ultra pasteurizeda modern flash-heating and cooling technology that keeps milk fresh, safe and nutritious for a longer time than does traditional pasteurization.
