To be labeled an Oregon wine, at least 75% of the wine’s grapes must have been grown in Oregon. In some cases, a wine can be labeled under two states, such as “Oregon/Washington”, though there are strict rules governing the labeling of such a wine. There are Oregon wineries that produce Washington appellation wines, and vice versa. The area in which the grapes were grown determines the appellation of the wine.
