First made in 1982, the John Riddoch Cabernet Sauvignon was conceived as a flagship wine for the Wynns portfolio. The wine honours pasturalist and parliamentarian John Riddoch, who was the largest land-owner in South Australia’s south-east corner. With his brother George, the two owned the freehold to more than 70,000 acres.

Deep crimson. A wonderfully evocative wine. Fragrant pure blackcurrant, dark cherry aromas with integrated praline mocha, roasted chestnut notes and touches of sage and violet. Beautifully concentrated wine with voluminous blackcurrant, dark cherry, mulberry fruits, plentiful fine grainy al dente tannins, superb dark chocolate, mocha, espresso complexity and underlying chinotto sage notes. Finishes grainy/ cedar firm with pure cassis, kirsch notes and a plume of extract. Elegant, powerful and expansive with the structure and balance for long term aging; the fruit, tannin, oak and acidity are beautifully integrated. Rating: 99 Points; Andrew Caillard; Master of Wine

Very deep, dark, brooding purple/red colour, with a remarkably complex, savoury bouquet of beautifully-integrated fruit and oak, very ripe cabernet aromas with zero leafy or green notes and lots of dark brooding black fruit and cassis characteristics intertwined with cedar, smoky-bacon and graphite nuances. The wine is almost decadently rich and fleshy, full-bodied and loaded with extract, the abundant tannins extremely supple and superbly knitted into the fabric of the wine. Riveting intensity. A glorious cabernet. Date Tasted: September 2021; Drink: 2023 to 2048; Price: $150.00; Alcohol: 14%; Rating: 98 Points; Huon Hooke; The Real Review

Oh my, this is such a good wine – as good as any that have been released under this label. It is remarkable that a wine of such finesse and refinement should also have such power and drive. But that’s Coonawarra in a good year, managed with first rate winemaking after the viticulturist has delivered the fruit. Has a slightly liqueur cherry aroma with cool leaf and tobacco leaf nuances. The palate is sublime with the fine weave of tannin, fine grained oak and silky-smooth fruit. As you might expect it is still a little shy and closed but decanting will give you a glimpse of what it will become. Drink: 2025 to 2045; Price: $150.00; Rating: 98 Points; Ray Jordan

Wynns’ flagship cabernet, selected from the best estate vineyards and refined even further from the top one per cent of the harvest. Without question, this wine exhibits the most elite nuances imaginable of dark berry and mint chocolate aromatics and flavours, enhanced by an exciting tension in the palate with energetic acidity pulsating underneath and lively tannins offering support from the sidelines as all the elements swell with promise and delight with immediate pleasure. The structures here suggest extraordinary longevity. Top of the tree. Drink: 2025 to 2045; Price: $150.00; Rating: 98 Points; Tony Love

This is Wynn’s flagship wine and justifiably so. Not made every year, as the vintage has to be a good one, it stills manages to sit comfortably with the best cabernets made in this country, and has done so since the very first vintage back in 1982. It is a wine that has great longevity. 2018 is a great vintage for John Riddoch. So careful are Wynn’s with this wine that only the best grapes are used – less than one percent of their finest cabernet qualifies as suitable for the John Riddoch. The wine is utterly seamless with a supple creamy texture. Notes of chocolate, blackberries and mint, florals and even the merest hint of red berries. This is certainly the most refined wine in the Collection. It is both elegant and powerful, a very fine line to tread. The intensity is maintained throughout with good acidity and very fine, silky tannins. An exquisite cabernet, one of Australia’s best. Rating: 98 Points; Ken Gargett
