The Twenty Mile Bench stretches east to west from Fifteen Mile Creek to west of Cherry Avenue. Bisected by Twenty Mile Creek, it has a complex topography with a distinctive double bench formation west of Twenty Mile Creek, and short, varied slopes that roll to the brow of the escarpment. Cultivation here focuses on the red skinned Cabernet Franc and Pinot Noir, and the white Riesling and Chardonnay.
