Our Filet Mignon are hand cut from hand selected Certified Angus Beef© brand Natural tenderloin that have been aged 21 days to perfection. This cut is known for being the most tender of all cuts available. The Certified Angus© Beef standard is more selective than USDA Choice and Prime. The secret to the Certified Angus Beef© brand’s outstanding flavor is marbling, the little white flecks within the meat that ensure every bite is flavorful and juicy. Niman Ranch cattle are raised with care and only fed a 100% vegetarian diet.
