Clare Valley arguably produces Australia's best Riesling and Petaluma's Hanlin Hill Vineyard provides the fruit for Petaluma Riesling, recognized in Australia as the best of this traditional dry style. Clare lies in a valley in the northern extension of the Adelaide Hills, 90 miles (145km) from Adelaide.
The geology of the Hanlin Hill Vineyard is Mintaro shale, deposited as shallow marine sediments between 550 and 600 million years ago, and metamorphosed into high quality grey slate, which has weathered to form well draining, brown to red-brown clay rich soils.
"Bright straw-green; immensely precise and authoritative, a clarion call of terroir speaking; a firm and classic mix of lime, lemon spice, with a lingering, dry minerally finish. "
Australian Wine Companion
"Crisp in texture and generous in flavor, a seductive mouthful of Bosc pear, white peach, lime and green tea flavours, lingering on the polished finish. This one has depth and distinctive character."
"Simultaneously floral and minerally on the nose, the 2006 Hanlin Hill Riesling is an all-around delight. Filled with apple, nectarine, melon and lime fruit, it manages to conceal the Clare Valley’s sometimes hard edges with ripe fruit. Finishes dusty, minerally and long; this should have a long, positive evolution. "
