Appenzeller Extra, is a relatively rare limited production full-fat, semi-hard cow's milk cheese.
Cheese makers, carefully select the best of the Appenzeller cheese wheels—those that fulfill a rigid set of standards—to mature for longer periods and become Appenzeller Extras.
One of the key characteristics of Appenzeller is the brine curing process every cheese wheel undergoes. Each cheese is treated with a mixture of wine, spices and herbal brine, the recipe for which remains a well-kept secret known only to a few. The brining lends a spicy character that grows stronger the longer the cheese ages.
