Testing the Potential of Rubaiyat Grape as a Coloring Blend for Oklahoma Red Wines

In this episode of The Food Files, William McGlynn, FAPC horticultural products processing specialist, discusses his research of testing the potential of Rubaiyat grape as a coloring blend for Oklahoma Red Wines. Rubaiyat is a hybrid grape variety developed at Oklahoma State University by Herman Hinrichs and introduced in 1975. Although the grape has been grown in a handful of vineyards around the state, it has never seen widespread commercial production and very little research has been done on its winemaking properties until now.
