Grass-Fed simply means that the animals were allowed to forage and graze for their own fresh food. During the winter they may be provided substitutes like alfalfa, the focus is on providing the closest thing to a natural diet as possible. Grass is much higher in key nutrients like Omega-3s and B vitamins, and result in steaks that are leaner, healthier, and much more flavorful. Organic is not about how the cattle is raised, as is the case with Grass-Fed, but it describes how the animal was NOT raised. Organic animals CANNOT be confined in a feed lot for any extended period of time, cannot be over-crowded or kept in unsanitary conditions, and cannot be directly or indirectly exposed to artificial pesticides, fertilizers, antibiotics, hormones, GMOs, or other synthetic contaminants.
