Hardy to -38F. This selection is widely planted for its lower acidity and neutral aromatics. It is an ideal blending component for dry white wines to lower the overall acidity and add body and finish. Sometimes Prairie Star is made as a varietal or with a small amount of something more aromatic, and then barrel fermented. This is a wine style that resembles some California Chardonnays, but is made from fully hardy grapes. Acidity is typically below 1% with 20-22 brix. Both Prairie Star and Louise perform well on heavier soils with more silt and clay. Should be well irrigated on sandier sites. Growth is somewhat upright. Mid season bud break and early season ripening. Selected by Elmer Swenson.
