This cheese is produced in the central cantons of Switzerland. It is a traditional, unpasteurised, hard cheese made from cow's milk. It's hard, thin rind is covered by paper with producer's name on it. The aroma is sweet with tones of fresh-cut hay. The flavour is very fruity, not without a tone of acidity. Emmental has walnut-sized holes. It is considered to be one of the most difficult cheeses to be produced because of it's complicated hole-forming fermentation process.
