In 1937, Walter Clore arrived in Prosser, Wash. and began to change his corner of the world. The 26-year-old horticulturalist had been dispatched to the new Irrigation Branch Experiment Station to identify eastern Washington's most advantageous crops. Fruits for jelly and vegetables were the focus. Clore decided to also plant seven Vitis vinifera, i.e. wine grape vines.
