Castle Rock is situated in the Great Southern region of Western Australia. The winery has a reputation for exceptional Riesling that are not only elegant but also have the ability to age beautifully. The newly released 2008 vintage is one of their best, displaying power, balance and wonderful length of flavour.

"96 Points. Family member and winemaker Rob Diletti has gained skill and experience as the estate vineyard has aged; it’s a potent combination. Still gloriously youthful, citrus and mineral interwoven, edging slowly but surely to the day five years out when it will start to display everything it has to offer; it will be magnificent. From Porongurup; Drink to 2023 with tuna sashimi. $21, Screwcap, 12.5% alc" - James Halliday, Top 100 Wines, The Weekend Australian, November 14-15, 2009. 

"A long, lean and nervy young riesling with a penetrative, musky bouquet of white flowers, apple, lime and minerals. Supported by a dusty chassis, its tightly sculpted palate of intense lime juice and lemon flavour finishes with a fresh bite of citrusy acidity. (18.0/93, YTD 2016-2020)" - Jeremy Oliver, jeremyoliver.com.au. 

"Pale straw with green hues. A tight, citrus dominated, nose, showing lime and lemons characters. Some light floral notes, orange blossom and a minerally edge adds interest. The palate is Riesling in its purest form, tight and elegant and dominated by citrus fruit characters. The natural acidity is powerful yet wonderfully balanced and gives the wine a mineral structure and great length. The wine is tight and restrained with an attractive delicacy now, yet will blossom with age for ten years. Ideal aperitif wine, will also accompany fish and delicate crustacean and mild Asian dishes." - Notes from Castle Rock.
