Forget the lower case “a&w” this is Castle Rock Estate’s new flagship, named in honour of the founders Angelo and Wendy Diletti.

Castle Rock Estate, a&w, Riesling, Porongurup, 2022

Near water pure in hue. Restrained and shy nose: torn kaffir lime leaves, stony white rocks, kisses of jasmine blossom, chalky talc, lemongrass stalk and suggestion of richer herb oil. This is such a joy to taste: bright, alive fruit powered with vibrant acidity and stacked with intensity through a long, long linear finish. Green apple, jasmine and slate if you need descriptors. This will only get better and better.
