The 2016 Wynns John Riddoch Cabernet Sauvignon is a red wine originating from the Coonawarra region in South Australia. Notable for its screw cap closure and 13.7% alcohol content, this Cabernet Sauvignon has garnered significant acclaim from professional wine reviewers.

James Suckling of jamessuckling.com awarded this wine a score of 95, highlighting its rich array of ripe blackcurrants, mulberries, and blackberries, alongside a cedary and gently chalky edge. He describes it as having "a very rich and powerful core of deep-set fruit, as well as a thread of rich chocolate flavor and a very polished, assertive core of tannin that holds super long."

James Halliday, writing for James Halliday, rated the wine even higher, with a score of 98. He notes that it is produced from a tiny fraction (about 1%) of Wynns' cabernet crush, handled meticulously in a specialized winery. Halliday describes it as "densely coloured, its amalgam of cassis and bay leaf held within a fine web of ripe tannins," attributing its high quality to an excellent vintage.

Decanter provided the most enthusiastic review, awarding the wine a near-perfect score of 99. The review describes the wine as having "lots of lean muscle" that converts into "flavour power," with notes of pure blackcurrant, chocolate, sage, plum, and espresso, all bound in a "graphite tannic grip." The review evokes the lasting impact of the wine's flavor, comparing it to "the final piano chord in The Beatles’ A Day In The Life."

Erin Larkin of Robert Parker's Wine Advocate gave the wine 96+ points, noting its approachability and balance. Larkin praises the refined oak program for supporting and elevating the fruit, stating that it offers "mulberry, raspberry salted licorice, clove, tobacco leaf, jasmine tea, and brilliant length." She advises patience, recommending drinking from 2026 through to the late 2040s and beyond.

Finally, Josh Raynolds of Vinous rated the wine 94 points. He describes it as having "smoke-tinged cherry, cassis, and licorice scents," along with nuances of pipe tobacco, potpourri, and cola. On the palate, the wine is "concentrated yet energetic," with flavors of dark fruit, floral pastille, and roasted coffee, finishing with a note of vanilla shaped by polished tannins.

Overall, the 2016 Wynns John Riddoch Cabernet Sauvignon is highly regarded for its rich flavors, balance, and aging potential, making it a standout choice for Cabernet Sauvignon enthusiasts.
