Beaurocraptic nonsense

Any wine being distributed in the European Union (EU) produced after 8 December 2023 must have an ingredient label. The new legislation requires the ingredients to be listed in the languages of the countries to which the wine is shipped. The EU has allowed a QR code to be inserted on the label. The wine has to be tested by a certified lab. Only ingredients actually added to the wine must be specified, not those that were used in making the wine but later removed before the wine was bottled. 

American wineries dealing with new wine labeling requirements for wine exports to be sold in the EU got expert advice from panelists at the Unified Wine & Grape Symposium in Sacramento on a panel entitled “Prepping for Nutrient and Ingredient Labeling.”

So do winemakers have to break down the percentage of each grape varietal or identify the chemicals that make up the wine? If we don't add anything, do we just say Ingredients: wine?
