Veal – Though there are no precise age standards for veal, the term is generally used to describe a young calf from 1 to 3 months old. Milk-fed veal comes from calves up to 12 weeks of age who have not been weaned from their mother's milk.
Prime - It has an abundant amount of marbling (the network of fine lines of white fat). This marbling, as well as other factors such as feed quality, and aging, adds to the rich flavor and fine texture of the best cuts.
Choice - Choice can be nearly as good as Prime, especially in the top 2/3 of the grade. Generally, it tends to have a little less marbling.
Select - Select has less marbling than Choice, and will have even less complexity to the flavor.
Standard, Commercial, Utility, Cutter & Canned - Standard, Commercial, Utility, Cutter, and Canner, are not usually sold in grocery stores or butcher shops. They are usually reserved for uses that do not require better grades of beef. They come from older cattle, and the name "Canner" sort of explains itself.
Marbling – intramuscular fat that adds flavor.
Primal Cuts - basic sections from which steaks and other subdivisions are cut.
Doneness – Blue, rare, medium rare, medium, medium well, well done.
