What is the percentage of grapes required from a single vineyard for a wine labeled with that designation?

For a wine to be labeled with the designation indicating it comes from a single vineyard, it is required that at least 95% of the grapes used in the production of that wine must come from that specified vineyard. This high percentage ensures that the wine is truly representative of the unique characteristics of that particular vineyard, maintaining its integrity and quality.

The standard of 95% is significant because it not only reflects the commitment of the winemaking process to the specific terroir but also assures consumers that they are purchasing a product that adheres to strict regulations, offering distinct qualities attributed to that single location. This is particularly important in regions where the expression of the vineyard’s terroir is a critical aspect of the wine’s identity.
