The soil in this appellation is called Jory (primarily volcanic basalt), which provides the best drainage a grapevine could ask for. Hence, pinot noir loves this area. The location protects the vineyards from serious swings in daily temperature, and rainfall primarily occurs during the non-growing season. The early ripening pinot noir grapes thrive here, so even though you can find other varietals, remember that pinot noir is what you came to Oregon for! Expect a bit of minerality to accompany the fruit which is uncharacteristic of grapes grown in areas such as Russian River Valley.
