Opi Sadler has brought us the customer favourite ‘Waxed Bat’, now he presents the ‘Big Bat’. If you didn’t think a wine could get any richer, silkier and packed with luxurious layers of flavour, you were mistaken. But then, Opi is one of Argentina’s most internationally renowned winemakers and he adores the Cabernet Sauvignon grape.

To achieve such an ageworthy perfection, he selected grapes from the finest, high-altitude vineyards in Altamira, Uco Valley, ageing this grand red for 18 months in French oak barrels. This lends a spicy edge to the rich black fruits. Opi states that Argentina makes "undoubtedly the best Cabernet wines in the world". A big statement, but judging by this wine, he may well be right. An elegant, mature steak red.

Black Saint Peter comes to you from California’s premium Lodi district, the self-proclaimed ‘Zinfandel Capital of the World’. This grape thrives in the very warm temperatures of this inland region, particularly when grown on gnarly, old, low-yielding vines, some dating back to the 1880s. Zinfandel was brought to California in the 1850s by incomers from the East Coast attracted by the Gold Rush. Some of the first vines were called ‘Black Saint Peters’ until, 20 years later, they were identified as the same grape as Zinfandel.

This weighty, velvety red uses grapes from vines over 50 years old, making for deep and complex flavour in the glass. At a generous 15.5%, it’s a splendid food companion. Serve with barbecued spare-ribs or spicy tagine.

Formerly known as Capbern Gasqueton, this Cru Bourgeois Saint-Estèphe estate has been in the same family for 10 generations. It's the same family that owns 3ème Cru Classé Calon Ségur. It lies in one of the finest parts of the appellation, between Phelan Ségur and Meyney, and every aspect is given Grand Cru care. Hand picking of the 41 hectares of vines, with ageing in top-quality oak, all adds up to the exceptional quality.

This vintage has gathered many top scores from wine critics such as Jeb Dunnuck and James Suckling, who called it "full-bodied with a deep character". Two thirds Cabernet with almost the same in new oak, it has “gorgeous cassis, violets, classy oak, with beautiful tannins” (Jeb Dunnuck). One to cellar for a few years.

Finding a parcel of 2010 claret nine years after this 5-Star vintage was a coup for our Buyer Jean-Marc Sauboua. Critic Michael Schuster described the wines of 2010 on release as “massively elegant, fresher, firmer, more tannic”, Suckling praised them for being “very precise, focused and fresh to taste”, “dangerously good” said Jancis Robinson MW.

Médoc wines that year proved particularly good value too. The 40 hectare estate Château Carcanieux has very gravelly soils, hence its original name Carcanieux Les Graves. This encourages superb concentration and ripeness in the wines. Cabernet with Merlot, and aged in barrel, this silky claret has a fine balance of fruit and maturity, with spice from the oak. Decant and serve with steak au poivre.

Lying close to Margaux's Châteaux Giscours and du Tertre, Château Cazauviel remains surprisingly under the radar. It was inherited by Régis Bernaleau from his father in 1978 and today remains in family hands. It is situated on the prized gravel soils of the Arsac plateau, which lends both an intensity and a finesse to the wine. This pretty claret is from a vintage struck by early April frosts – the most devastating for many years.

It reduced yields, but as Decanter wrote, "there are some excellent wines." Most, like Cazauviel 2017, are not long keepers, but makes delightful drinking now. Ideally open a couple of hours before serving and decant. It'll make a delicious glass with roast chicken with morels or a mushroom croustade.

Fronsac's fine Château Dalem perches high on a hill, surrounded by its 14 hectares of sloping vineyards. It's an historic estate, with records dating back to 1610, that stayed in the same family until 1955. Michel Rullier then took it over and today it's run with great success by his descendant, Brigitte Rullier-Loussert. Its vineyards are nearly all planted to Merlot, with a small amount of Cabernet Franc, and tended with meticulous care.

As you can see from critics' scores (92 points from James Suckling and 94 from Vertedevin), it is an admired claret and one that ages very well too. Matured in French oak (50% new), it has structure and length, but above all an appealing fruity depth. Perfect with roast meat or wild mushroom risotto.
