Bündner Alpkäse is a semi-hard, full-fat cheese, made exclusively from raw cow’s milk in alpine dairies during the summer months. Under the Swiss Mountain and Alpine Ordinance, it must be produced in high-altitude pastures, where cows graze freely on rich alpine vegetation.
A wheel weighs between 4 to 6 kg, with a firm texture and small holes, and it is available in mild (2-3 months), spicy, and tangy (6+ months) varieties. The cheese is made by mixing evening milk (partially skimmed) and fresh morning milk, ensuring a minimum fat content of 45% in dry matter.
Coagulated with rennet at 32°C, the curds are cut into small grains and heated to 45-47°C to extract moisture. The curds are then pressed into molds for 24 hours, brined for 1-2 days, and aged in cellars, where bacterial cultures and natural smear flora develop, forming its distinct reddish-brown rind.
