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.

When Australia's top cellars need fast, upfront cash they come to our buyer, Dan Parrott. Dan'll keep their name a secret in exchange for a low price on a cracking wine. True for this rich Cabernet with its bold cassis fruit.

If you love premium Aussie reds and are keen on a great deal, our Cleanskin wines are just the ticket. This is from a highly sought-after cellar within South Australia. Home to many of the country's best-known premium regions – Coonawarra, the Barossa, McLaren Vale and more – it has an ideal climate for making bold, ripe, characterful reds, like this one.

This hush hush Cleanskin deal came about thanks to the unnamed cellar slipping our man Dan a word, telling him about a spare parcel of wine that had no home and needed one quick! Delighted to help, Dan snapped it up before anyone else could. Pure Cabernet, it's dark and bold, well-structured and long. For now, it's well worth opening early and decanting. Enjoy with steak or hearty dishes.

Critic Jancis Robinson MW was impressed by "the great strides that have been taken in red wine quality" in South Africa. After a tasting, she wrote, "Most of the reds I encountered were really delicious — with fine examples of Cabernet Sauvignon". This ace red is from the De Wet winery in Robertson. It's a 19th-century family estate with extensive plantings of Cabernet (nearly half their vineyards) and count themselves specialists of this grape.

For the Heritage Reserve, winemaker Johann Stemmet searched out the finest, lowest-yield grapes from the limestone soils of this great region. Ageing nearly half the wine in French and American oak has lent a rich layer of spice to the dense notes of cassis. Open early and get the steak sizzling.

The name William Knuttel resounds in California fine wine circles. In the 1980s, Knuttel was key to establishing Saintsbury as a leader of fine Pinot Noir and Chardonnay, and later helped build a great reputation for Chalk Hill and Dry Creek wineries too. In 2001, he founded his own estate and today is joined by his son and daughter.

This full-bodied, velvety red is pure Cabernet, sourced from Wilson Vineyards in Clarksburg. Just east of San Francisco Bay, the site benefits from cooling sea breezes and rolling mists that encourage long, slow ripening of the grapes. 14 months ageing in French oak barrels has lent layers of gentle oak spice to the dense dark fruit of this Cabernet. A great red to serve with roasted red meats or hearty bakes.

Using the very best grapes, this is a dark, spiced, velvety-rich treasure rated 92pts by the great James Suckling.
