Campbelltown is located in the Adelaide metropolitan area, falling within the Adelaide Hills wine region in South Australia. The region's cool climate, influenced by varying altitudes, is ideal for cultivating early-ripening grape varieties, although some slopes can ripen Cabernet Sauvignon. Key grape varieties grown in Adelaide Hills include Sauvignon Blanc, Pinot Noir, Chardonnay, and Shiraz, producing notable wines like complex Chardonnays and high-quality Pinot Noirs known for ripe fruit flavors.
Sauvignon Blanc is a widely planted white grape in the region, offering tropical flavors, herbaceous notes, and crisp acidity. Penfolds Winery in Magill, South Australia, founded by Dr. Christopher Rawson Penfold, has a storied history in the region. Initially focusing on Port and Sherry, the winery later expanded to include Claret and Riesling varieties. With cool temperatures aiding in the production of balanced wines, Penfolds has played a significant role in the South Australian wine industry's development, building a profitable export trade and expanding into various regions within the state.
