      Queso Leyden

Boeren-Leidse met sleutels (also known as Boeren Leidenkaas ) is traditional farm-made Leidse kaas protected by a PDO (Protected Designation of Origin) certification. For more than 500 centuries, the production of the cheese has taken place in the vicinity of the Sleutelstad Leiden.


Traditional Boeren-Leidse is cumin infused semi-hard farm cheese with a firm and somewhat crumbly texture. This is because it is prepared from raw, semi-skimmed milk with a fat content between 30 and 40%. The wheels are covered in a red-brown, waxed natural rind, which is not suitable for eating. Boeren-Leidse met sleutels can be easily recognized by the crossed keys logo imprinted on it by the Members of the "Association of Farmers Leiden Kaasmakers".


This cheese has a powerful, rich flavour with that extra zing of cumin. It is gently aromatic and becomes more fruity and intense as it ripens.


PDO (Protected Designation of Origin)(ES). Protected designation of origińe (PDO) stands for a product for which the principal steps for production are done following a well-established technique within the same geographical area, which gives the product its characteristics. Year of registration 1997
