AVA (American Viticultural Area) is a US geographic designation protecting wine-region names. AVAs are federally recognized geographic areas within which wine can be produced if at least 85% of grapes come from that area. AVAs include broad regions (Napa Valley) and specific sub-regions (Rutherford in Napa). AVA designation ensures geographic authenticity but doesn't mandate quality standards (unlike European appellations). Understanding AVA hierarchy helps evaluate American wine provenance.
WHY IT MATTERS FOR COLLECTORS
AVA designation ensures geographic authenticity but not quality. Within an AVA, quality varies significantly by producer and sub-appellation.
