The Tiers Vineyard is a time proven “distinguished site”. In 1979, it was the first vineyard planted in the modern Adelaide Hills wine region, thus pioneering the ultra cool climate wine industry of South Australia. The Tiers Vineyard is in the Piccadilly Valley, the wettest and the second coolest site in South Australia. Only Parawa on the Fleurieu Peninsula is marginally cooler.

The Piccadilly Valley is well suited to Chardonnay, being an almost perfect homo-clime of Burgundy. The soil under the Tiers Vineyard is unique in the Adelaide Hills being based on the 1.6 million year old calcsilicate geological stratum lifted into place by a fault at the edge of The Tiers Vineyard. The rest of the Adelaide Hills has geological strata 500 to 800 million years old.

The Tiers Vineyard tilts gently to the North and East in a sheltered valley that receives the best advantage of the autumn sun in the northern sky to absorb the last rays of ripening energy at the cool end of harvest.
