Organic Valley says it added Organic Valley fat-free Grassmilk. The fat-free option joins the La Farge, Wis.-based cooperative’s current lineup of whole and reduced-fat 2% Grassmilk. All Organic Valley Grassmilk is made with milk from third-party certified grass-fed cows on organic family farms, which means that cows are on pasture for more than 150 days per year and are fed 100% grass and dried forages year-round, never grain. The fat-free Grassmilk also contains essential nutrients such as vitamins A and D with the same nutrient density and 100% commitment to grass-fed as the rest of the product line. The resulting milk features the subtle seasonal flavors of the pasture that consumers look for in a grass-fed product.
