Certified Naturally Grown beef kidney. We purchase these 6 month old Angus steer and grass feed them for 2 more years. 30 days before taking the 2 1/2 year old old black angus steer to the processor we supplement a small amount of locally grown organic grain while still allowing him to eat all the grass he wants. This method helps to add a little bit more flavor and tames the grass fed flavor to something we enjoy more. These steer only get reclaimed rain water to drink. They are processed at a USDA inspected facility and vacuum sealed to preserve freshness.
