Petaluma is one of Australia's most essential producers, famous for seeking out the finest terroirs in South Australia to its grapes. Riesling comes from the Hanlin Hill vineyard in the Clare Valley, Chardonnay from the cool climate Piccadilly Valley in the Adelaide Hills and Cabernet from Coonawarra. Andrew 'Ox' Hardy, a member of the original Hardy wine family and a walking encyclopedia of South Australian wine, is now the man at the helm, ensuring these vineyards have a very exciting future.
