"Rob Diletti's excellent palate and sensitive winemaking mark Castle Rock as one of the superstars of WA."

Halliday Wine Companion

Castle Rock Estate is nestled on the eastern slopes of the Porongurup Range and is named after a prominent nearby landmark, in the Great Southern wine region of Western Australia. The vineyard has a cool and elevated north-easterly aspect, resulting in intensely flavoured wines, particularly Riesling, Chardonnay and Pinot Noir. Castle Rock Estate was established in 1983 by Angelo and Wendy Diletti and is now run by their son Rob.

Castle Rock Estate Riesling

After 30 vintages Castle Rock Estate Riesling has gained a significant reputation for its quality and ability to age. There are six different vineyard blocks of Riesling allowing us to carefully select the fruit for our various styles of Rieslings.
