Triple Creek Natural Lean Beef comes from our own home grown steer calves which we have raised from our own Sim-Angus herd in Greeley, Colorado. We do NOT buy calves to feed. We are a family operation and all beef is Free Range fed in grass pastures on the farm. We grow our own hay and use no herbicides on our hay or pastures. Our beef is ALL NATURAL, which means we give our cattle no hormones, insecticides, vaccines or antibiotics. All of our beef is dry aged a minimum of 21 days to ensure superior marbling, the richest flavor, and unsurpassed tenderness. These steaks exceed USDA standards, and are the most tender and the most flavorful cuts you'll find anywhere. Comparable to those served in the finest steakhouses of the world!
