OAR 845-010-0920: Appellation of Origin

(1) An appellation of origin must appear on every wine brand label in direct conjunction with, and in lettering as conspicuous as, the wine's class or type designation. (2) If the appellation of origin claimed or implied anywhere on a wine label is “Oregon”, the name of one or more of its counties, or the name of an American Viticultural Area wholly within Oregon, then all grapes used in the production of the wine must have been grown in Oregon, and 95 percent of the grapes used in the production of the wine must have been grown within the defined boundaries of that appellation of origin. (3) If the appellation of origin claimed or implied anywhere on a wine label is the name of an American Viticultural Area located in both Oregon and an adjoining state, then all grapes used in the production of the wine must have been grown in Oregon and/or that adjoining state, and the percentage of grapes grown within the federally defined boundaries of that American Viticultural Area must satisfy the least restrictive of: (a) The 95 percent minimum described in section (2) of this rule; or (b) The minimum percentage of grapes required by the adjoining state for the use of that American Viticultural Area as an appellation of origin.
