The Jessie Vineyard, named for winegrower-owner Tom Gerrie’s great-grandmother Jessie Summers, was established in 1994 after the Gerrie family saw great potential in planting a steep, east-facing hillside. Ranging in elevation from 320 ft to 550 ft (98 m to 168 m), this 11.53 acre (4.67 hectare) site is one of the steepest in Oregon, and the most challenging to farm on the Cristom Estate.
