Walter J. Clore was a pioneer in wine growing and agricultural research in Washington state and has been formally recognized by the Washington State Legislature as the "Father of Washington Wine". Among his contributions to wine growing in Washington state was his extensive research into what areas of the state that premium wine grapes would most thrive in.
In 1934, Walter Clore married Irene Welsh and accepted a horticultural fellowship at Washington State College in Pullman, Washington. One of his first studies there was to measure the effect of "Bordeaux Sprays" on the photosynthesis of red and golden delicious apples. In 1937, Clore became assistant horticulturist at the Irrigation Branch Experiment Station in Prosser. There he oversaw the experimental plantings of nearly 20 Vitis labrusca hybrids and 7 Vitis viniferagrape varieties. In the years that follow, under Clore's direction the plantings at the Experiment Station would expand to include 45 hybrids, 71 Vitis vinifera, and 10 interspecies Vitis hybrid rootstock. By 1974, Clore had overseen the plantings of 312 grape varieties. His work laid the foundation for the rebirth of the Washington State Wine industry as it conclusively proved that premium quality vinifera wine grapes could be grown in the rich volcanic soil and warm climate of the Columbia River Valley. His test of trellis designs helped to promote the widespread adoption of modern mechanical harvesting techniques.
