Tyrrell retain some of the finest vineyards throughout Australia, a tremendous resource from which to collate parcels of premium quality fruit to craft some of the nation's most popular wines. Chardonnay grapes for Old Winery are principally sourced from good estate vineyards in the Hunter Valley, choice parcels selected for their capacity to enhance structure, complexity and weight of palate. Local components are grown to the estate's Pokolbin and Ashmans Vineyards at the heart of Lower Hunter Valley, very near the historic Pokolbin wineworks. After harvesting and the press, juices are treated to a cool ferment and extended time on lees, some parts receive a short spell of age in French oak barriques.
