The surface of the entire Taleggio PDO cheese wheel displays the four circles trademark, which must also be clearly visible on the portions sold. Its presence guarantees that the cheese has been produced in full compliance with the requisite technical and hygienic standards. The logo displays 3 Ts and a number, which identifies the dairy farm and which the Consortium uniquely assigns to each member (dairy farm or maturer). The cheese wrapping also carries the Consortium’s cloverleaf trademark (in red and green), containing the identification number, which is also unique and issued by the Consortium.
