Orchard Fresh, Inc., purchases apples from local orchards and sorts them into four categories. Grade A are large blemish-free apples that can be sold to gourmet fruit sellers. Grade B apples are smaller and may be slightly out of proportion. These are packed in boxes and sold to grocery stores. Apples for slices are even smaller than Grade B apples and have blemishes. Apples for applesauce are of lower grade than apples for slices, yet still suitable for canning.
