Complementary definitions relating to carbon dioxide content

I.3.3 Complementary definitions relating to carbon dioxide content

The wine is said to be :

  • Still, when the carbon dioxide concentration is less than 4 g/l at 20°C,
  • Semi-sparkling, when this concentration is equal to or above 3 g/l and less than or equal to 5 g/l at 20°C.

If the carbon dioxide content of the product enables the indication of these two references, the wine maker or the importer shall only use one reference of his/her choosing.
