Few would dispute that the Touriga Nacional is Portugal's finest red grape variety, deserving a place right up at the top of the world league of grapes, along with the likes of Pinot Noir, Cabernet Sauvignon and Nebbiolo. Though Northern in origin, it has spread right across the country - you will find it down south in the Algarve and the Alentejo, out west in the Ribatejo/Tejo and Setúbal regions, successfully competing with the local Baga grape in Bairrada, and way out mid-Atlantic in the Azores. Touriga Nacional is a thick-skinned grape, and those skins are rich in colour and tannins, giving excellent structure and ageing capicity. But it also has wonderful, intense flavours, at the same time floral and fruity - ripe blackcurrants, raspberries - with complex hints also of herbs and liquorice. Yields are never high. The Dão and Douro regions both claim to be the origin of this fine grape, and the rest of the winemaking world is beginning to wake up to its quality.
