Haymilk
Haymilk (, ) is dairy milk produced from animals that have mainly been fed fresh grass and (dry) hay, rather than fermented fodder. The milk is thus produced according to the tradition in the Alps. The term haymilk is registered as a traditional speciality guaranteed in the UK and the European Union, and can only be used for milk produced corresponding to those specifications. Production
The milk can only be produced from animals that received mainly hay (winter) and "fresh grass, leguminous plants and foliage" in summer, but also roughage like green rapeseed, green maize, green rye and fodder beets is permitted. For a maximum of 25%, also cereal crops (wheat, oats, rye, etc.) and beans, field peas, lupins, oleaginous fruits. Products like fallen fruit, urea and potatoes can not be used as feed, and sewage sludge can not be used as a fertilizer on the land. Traditional speciality guaranteed
Three different products were registered as a traditional speciality guaranteed, depending on the animal that is the source of the milk. In each case the name is registered in 5 languages, while a 2021 amendment request has been published to also include the name in Slovenian. Use in cheese 
Several cheeses must be made from haymilk: for example the protected designation of origin cheeses Vorarlberger Bergkäse, Vorarlberger Alpkäse, Tiroler Bergkäse and  Tiroler Almkäse. See also
