- Grapes, derived from organic farming, are used.
- It is necessary to check the values from sulfites (θειώδη) 30-50 mg per liter in relation to their conventional equivalent (depending on the residual sugars content).
- Practices such as partial condensation, partial removal of alcohol, removal of sulfur dioxide by a natural process, electrodialysis and use of cationic exchangers are not permitted in organic winemaking because these oenological practices significantly alter the composition of the product in terms of its true nature.
- The use of ion-exchange resins, thermal treatments, and reverse osmosis are limited.
