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.

This is one of those 'under-the-radar' regions I love to search out, home to the finest quality wines, but not so well-known. As Wine International says, "If it weren't for the [political] line dividing Castillon from Saint-Émilion, its wines would be twice the price. The hills are the same, the soil is the same, the exposure is the same." The estate has won over 150 awards, including the Paris Lauréat Prix d'Excellence – not once, but twice – and Decanter magazine calls it the "leading estate in the Côtes de Castillon". La Clarière is our flagship wine and absolutely no expense is spared. Low yields, careful hand-sorting, months ageing in the finest new French oak, and rigorous tasting ensure only the best parcels become La Clarière. Mostly Merlot, silky, elegant, and supple, with a dash of Cabernet Sauvignon for structure, and slightly portioned Malbec and Cabernet Franc for balance. It's truly magnificent!

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.

Take a minute to read the (literally thousands of) 5-star online reviews for Cabalié. This one is typical: “When my time comes to shuffle off this mortal coil, this is the wine I want in that final glass. It is simply, utterly, indescribably fantastic.” Its secret? It’s crafted by a master winemaker, Hervé Sabardeil, following the centuries-old style beloved of Roman centurions, who first made wine there. Raspberry-rich Grenache, with herby Syrah and Carignan, Cabalié has impressive concentration.

That’s due to the maturity of the vines, most well over 50 years old. The tiny berries they produce give Cabalié extraordinarily rich, ripe flavours. Boasting 8 Golds in as many vintages, this much-loved red is warming solo or with hearty dishes.

Founded 200 years ago, Château Pédesclaux is a magnificent estate, both in terms of wine and architecture. It combines the beauty of the 19th century with the modernity and technological advances of the 21st.

The additional work was undertaken by architect Jean-Michel Wilmotte, whose aim was to place “production at the heart of the estate within a high-performance building that is entirely fit for purpose and makes a harmonious whole with both the château and its surroundings”. It's quite something to behold.

Since the Lorenzetti family took ownership they've converted to organic. Their top wine is a rich, Cabernet-based claret, supported by Merlot, and finely expresses its gravel terroir. Still a young wine – best to cellar or open early.

Castillon is a tucked-away Right Bank Bordeaux appellation that, for too long, has lived in the shadow of its famous neighbour, Saint-Emilion. The two regions share the same soils, grapes and climate and the best Castillon wines certainly stand scrutiny next to the Grands Crus of the famous one. The upside is that claret lovers can still find Castillon wines at exceptionally good prices.

Château Joanin came into the Bécot family in 2001. It has the highest vineyards in all Castillon, in the lieu-dit of Joanin. Juliette Bécot is today in charge and, with the renowned Bordeaux winemaker Thomas Duclos as consultant, it’s clear they are aiming high. Merlot with Cabernet Franc, aged 50% in new oak, this is a rich red. Open early and decant.
