DEAN & DELUCA is proud to offer natural beef, which comes exclusively from a family-owned herd in California. These pure-bred steers are raised naturally and humanely. This true natural herd is grain, grass and corn-fed for over three hundred days without the use of antibiotics or growth hormones. This natural feeding process means that the animals take an additional forty-five days to reach market. Dry aged for a minimum of thirty days for maximum tenderness and taste. Available fresh or frozen.
