'Sovereign Tiara' (Vitis spp. hybrid) is the second of two white wine grape cultivars recently released by the Agriculture Canada Research Station, Summerland, B.C. Like `Sovereign Opal', 'Sovereign Tiara' is a latemidseason grape cultivar useful for both varietally labeled and proprietary products. Consistently high yields make 'Sovereign Tiara' ideal for use as a bulk blending grape, and render it advantageous over 'Sovereign Opal' for this purpose. Compared to 'Okanagan Riesling', yield and winter hardiness of `Sovereign Tiara' are superior, while fruit composition is comparable.
