Petaluma began in 1976 with the philosophy of growing the best grapes in the region they are best suited for. From this ethos, a portfolio grew which consisted of Cabernet Sauvignon from Coonawarra, Chardonnay and Shiraz from Adelaide Hills and Riesling from Clare Valley. Fruit is grown in specially selected vineyard sites in sub-regions that further show ideal properties for getting the best out of the specific varieties. In Adelaide Hills they identified the Piccadilly Valley for it’s great potential for producing top Chardonnay, and is home to some of the first Chardonnay vines planted in Adelaide Hills. Fruit from these vineyards are used to produce their Tiers Chardonnay whilst their Yellow Label B&V Shiraz certified organic vineyard Shiraz from Mount Barker.
