Like the brightness and purity that the name conjures, Chardonnay from the Oak Knoll district is known for its uncommon focus. The Chardonnay fruit from the Big Ranch Vineyard is known for its elegance and balance and Chief Winemaker Mark Beringer has always gravitated towards this acid-driven, food-friendly style of Chardonnay.
