Tyrolean grey cheese

Tyrolean grey cheese is a strongly flavoured, rennet-free cows-milk Sour [milk cheese|acid-curd cheese] made in the Tyrolean Alp valleys, Austria. It owes its name to the grey mold that usually grows on its rind. It is extremely low in fat and it has a powerful penetrating smell.
The cheese produced in Austria is registered as protected [designation of origin], Austria generally indicated in German as g.U. under the official name Tiroler Graukäse. The registration of the PDO states that its production has been a significant element of Tyrolean peasant gastronomy for centuries. Graukäse produced in Italy is protected by a prodotti agroalimentari tradizionali designation. Graukäse making became widespread on farms due to the simplicity of making and the availability of low-fat milk after the fat had been taken for use in butter making.
