As with many other varieties, the name "Fontina" has derivatives such as "Fontinella", "Fontal", and "Fontella". Although the version from the Aosta Valley is the original and the most famous, a derivative production occurs in other parts of Italy, as well as in Denmark, Sweden, Quebec, France, Argentina, and the United States. The Swedish and Danish versions are often found in US grocery stores, and can be distinguished from Aostan Fontina by their red wax rind (also prevalent in Argentine Fontina).
