According to federal law, a wine labeled by an AVA within Oregon must contain what minimum percentage of grapes grown in that AVA?

For a wine to be labeled with an American Viticultural Area (AVA) designation within the state of Oregon, it must contain a minimum of 85% of grapes that are grown within that specific AVA. This requirement is in place to ensure authenticity and quality, allowing consumers to have confidence that the wine reflects the characteristics of that particular region. Oregon has established distinct AVA regions, each with unique terroirs, climates, and grape varieties, and the 85% rule helps maintain the integrity of the designation.

This threshold is higher than for general wines labeled simply as varietal, which require only 75% of the specified grape variety. It also underscores Oregon's commitment to promoting and distinguishing its smaller, more unique wine regions. By adhering to this standard, producers convey a stronger identity and origin, which is essential in the competitive wine market.
