A Syrah-Viognier co-ferment from 1,400-metre vineyards in Gualtallary is a rare thing in Argentina, and Alejandro Vigil's version is rest...

Atlantic Galicia, where rain and granite give Albarino its salinity.

Corpinnat is a breakaway from Cava, created by growers who wanted stricter rules on organic farming and longer ageing.

Rosso di Montalcino is Brunello's younger sibling — the same Sangiovese, less ageing, a third of the price.

Rhone white varieties in Paarl — Grenache Blanc, Piquepoul, Roussanne and Marsanne — which almost nobody in South Africa attempts.

A different block from the same producer, named for its latitude.

Sauvignon Blanc blended with Semillon and barrel-worked, which is white Bordeaux's formula and almost unheard of in Marlborough.

The same extreme southern climate applied to a white grape, giving unusual concentration and acidity.

A blend of Sauvignon Blanc, old-vine Semillon and Chardonnay from three separate high-altitude sites, fermented and aged in concrete eggs.

Made in a deliberately oxidative, old-fashioned style with flor influence, which is highly unusual for Argentina.

Bonarda is Argentina's second most-planted red and its most overlooked, usually blended away into cheap wine.

Mourvedre, Carignan and Grenache — a southern French formula almost nobody attempts in Chile, grown near the coast where it stays fresh.

The entry point into VIK, blending Cabernet Sauvignon with Carmenere.

Maipo Alto sits on the foothills of the Andes, where cold air draining off the mountains keeps Syrah peppery rather than jammy.

Limari is semi-desert with limestone soils — unusual in Chile — on the edge of the Atacama.

Leyda sits a few kilometres from the Pacific, cold enough that ripening takes months longer than inland.

Chenin Blanc is barely grown in Argentina, and this is one of very few serious examples.

The house red, made to be drunk rather than admired.

Vermouth made from wine rather than industrial spirit, infused with dozens of herbs.

Turkish wine from the Aegean highlands, made from indigenous varieties.

Pinotage carries a difficult reputation, largely earned in the 1990s by wines that were rustic and overworked.

White Port is Portugal's best-kept secret, served long over ice with tonic in Porto itself.

Koshu is a pink-skinned grape grown in Japan for over a thousand years, making pale, delicate, low-alcohol white built for sushi.

Coastal Tuscan Vermentino, softer and rounder than the Sardinian style.
