Aged over 60 days. Premium natural cheese. In a class by itself. Actually, American cheesemakers, not Swiss, modernized Swiss cheese production. Forty or fifty years ago the only way to protect Swiss wheels as they ripened was to allow a hard rind to form. The advent of a special plastic packaging that keeps moisture in but allows carbon dioxide to escape made it possible to produce rindless Swiss cheese in blocks. Swiss is mellow, buttery and nutty making it perfect to use for soups, sauces, fondue, salads, sandwiches and casseroles. Food Affinities/Parings: Apples, pears, and grapes. Best with: Merlot and White Zinfandel wines. Your comments are welcomed! 1-800-672-8260. Product of USA.
