Prosser is the historic heart of Washington’s first wine appellation and home to Dr. Walter Clore, Washington States’ wine pioneer. He began growing European wine grape varieties in a small experimental block in the late 1930’s at Prosser’s WSU Irrigated Agriculture and Research Extension Center (IAREC). Dr. Clore convinced growers in the late ’60’s – early 70’s, that vinifera wine grapes could be grown successfully. By the time he retired in 1976 his work blossomed to include over 312 varieties.
Currently, Prosser is seeing rapid growth in the wine industry. There are over 75 wineries within a 50-mile radius, making Prosser the ideal home base to explore “Wine Country”. A large majority of Prosser wineries are located within and between two winery cluster developments, the Prosser Wine and Food Park, I-82, Exit 82, and the Prosser Vintner’s Village located near the I-82 Exit 80, Gap Road interchange. The parks and two mile corridor between them, house over 20 wineries and the site of the Walter Clore Wine and Culinary Center.
