Wiens Ranch Premium Beef Colorado Raised & Humanely on Wiens Ranch We believe in providing the best possible care for our land and our cattle, from calving to finishing. We strive to be good stewards by reducing stress, providing fresh water and cool mountain air, freedom of movement, and rotation of pastures. Our pastures not only produce grass for our cattle they produce rich nourishing high-protein hay for our horses. Our cattle have access to our pasture system and are moved on a planned rotation basis to maximize nutrition and sustainable production of our pastures through our proven method of raising cattle.
