What percentage of grapes is required from a stated area for a wine labeled with the country, state, or county designation?

For a wine to be labeled with a designation indicating its origin from a specific country, state, or county, it is required that at least 75% of the grapes used to produce the wine must come from that designated area. This regulation ensures that the wine reflects the characteristics and quality associated with that particular region, which can be influenced by factors such as climate, soil, and local winemaking traditions.

The specified percentage guarantees that the wine has a substantial connection to the region, thus allowing consumers to have confidence in the origin of the wine. This standard is part of the broader system of labeling laws that helps maintain the integrity and quality of wines produced across different geographies. In some cases, higher percentages might be required for more specific designations or classifications, but for general country, state, or county labeling, the 75% rule is the baseline requirement.
