The Piccadilly Valley is the coolest viticultural region in South Australia and home to Petaluma's seven distinguished Chardonnay vineyards. Nestled in behind Adelaide's Mount Lofty, the Piccadilly Valley has a myriad of different slopes and sub-valleys. Petaluma now has the enviable position of seven mature age vineyards, up to nearly 30 years in age. Located at altitudes up to 600 metres, each vineyard has its own individual aspect and soil composition, with an underlying geology which ranges from 800 million to 1,800 million years old.
