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.

Once a sister property to Thomas Barton's Châteaux Langoa and Léoville Barton, 18th-century Château Le Boscq was purchased by Maison Dourthe in 1995. It then went through a complete renovation and a big step up in the quality of its wine. Its 18 hectares of vineyard, unusually in one single block, are planted on gravel and clay soils in the northern part of Saint-Estèphe.

Clay provides a cooler soil which favours Merlot, hence a higher than normal proportion of Merlot is planted – just over half, with 35% Cabernet Sauvignon, the usual hero of the Left Bank, plus Petit Verdot and Cabernet Franc. A year's ageing in nearly half new oak barrels adds to the gravity and longevity of this firm claret. Open early and decant or cellar a while.

An elite red with all the pedigree of the world’s finest wines. Think the great reds of Bordeaux, but richer and denser – swirling with dark fruits and seductive spices. Flavours that linger well after you’ve put down the glass. So where’s this stunning red from? France? Italy? Spain? No, it’s Lebanon. Called “the wine world’s best-kept secret” by Master of Wine Tim Atkin, this country has been making fine wines for thousands of years.

Not to mention, Ixsir winery is one of Lebanon’s best. No surprise really, considering the legend who works for them. Hubert de Boüard is the winemaker behind Saint-Émilion’s £250-a-bottle Château Angélus. At a much kinder price this sophisticated, spicy red is a special treat that's hard to put down.

Next door to Rioja, Navarra has always been less traditional. Its winemakers were some of the first to break rank and grow non-traditional Spanish grapes. A daring move, but one celebrated now – Navarra Cabernet continues to impress.

This mellow 2017 comes from the 65-year-old Señoria de Sarria bodega, an estate highly regarded throughout the world which lies in Puente La Reina. The fruit that went into this wine usually goes into their flagship Reserva Especial, but winemaker Milagros Rodriguez put some aside to make this exciting blend.

Powerful Cabernet Sauvignon with silky old-vine Graciano, aged two years in barrel and another four years in bottle, this is a magnificent, mellow red, packed with dark fruits and sweet spice. It needs time to open up, so decant if you can, and then serve with your finest roast lamb.
