What minimum percentage of a stated varietal must varietal wines from Oregon contain?

In Oregon, the law requires that varietal wines must contain a minimum of 90% of the stated grape variety in order to be labeled as such. This regulation is established to ensure the integrity of the wine's classification and to provide consumers with a clear understanding of what they are purchasing. By mandating that a significant majority of the wine consists of the announced varietal, it reinforces quality standards and helps to promote the characteristics typical of the grape. Thus, when a label claims a specific varietal from Oregon, it can be trusted that at least 90% of the wine is made from that variety, which is crucial for establishing the wine's identity and authenticity.
