Mainland is a New Zealander cheese made from pasteurized cow's milk. The cows are fed a diet of high-quality grass while grazing outdoors, resulting in a golden yellow color and sweet, creamy notes of the cheese. There are four types of Mainland cheese: sharp Cheddar (rich and sharp flavors), vintage Cheddar (strong), organic Cheddar (subtle and mild), and Egmont (nutty).
