They are cleaned using a machine and a blade in order to eliminate superficial mould. The frequency of this process depends on the external climate: in case of humidity and warmth more work is required on the cheeses in the cellar.
During this operation the staff check the appearance of each wheel and make a first selection of the Storico to be further matured.The selection process entails choosing the best cheeses to mature and cutting those that have small visible defects on the rind (mites or “carol”, swelling).
If the defects are likely to compromise the quality of the product, the wheels of cheese are classified as second choice compared to those approved by the Slow Food Presidia.
The best wheels chosen may be left to mature for 10 years or more.
