Urnäscher Hornkuhkäse is a distinctive cheese produced by Urnäscher Milchspezialitäten AG, a company located in the canton of Appenzell Ausserrhoden, Switzerland. This cheese is made from the milk of cows with horns, a rarity as many dairy cows are dehorned for safety and space reasons.

The practice of using milk from horned cows is based on the belief that it affects the quality and flavor of the milk, giving this cheese a unique profile. Urnäscher Hornkuhkäse is known for its rich and complex flavor, which is deeply influenced by the alpine grasses and herbs that these cows graze on.
