The vineyards of the Yamhill-Carlton District were planted mostly in the late 1980’s and early 1990’s. The primary soil of this area is called Willakenzie, named after the Willamette and McKenzie rivers. It is a sedimentary soil with a sandstone base rock. The sand content is quite high and the soil therefore very well drained. The sites are generally on the lower slopes of a volcanic ridge. Wines of the area possess aromas of red and blue fruits, with added elements of cocoa, leather, anise, clove and fresh-turned earth. Acidity levels are generally lower than other regions, prompting these wines to be lush and agreeable in their youth.

Shea is located 2 miles east of Yamhill, 140 total acres with original plantings dating back to 1989.
