Not before time, the Portuguese are making a determined effort to tell the outside world just how good their wines are. Isolation has its disadvantages but one strong advantage for Portuguese wine is that it is made from a dazzling array of high-quality vine varieties that are, for the moment anyway, rarely found elsewhere. The Portuguese government is planning to promote Wines of Portugal in export markets. At present only Angola and Macau really seem prepared to pay for Portugal’s finest wines, and the country’s most valuable wine-related export by far is not wine but cork. But, perhaps even more importantly for Portuguese wine’s long-term future, the government is backing a project to preserve Portugal’s unique viticultural heritage. This could be well-timed in view of the growing reverence worldwide for so-called heritage or heirloom varieties of all manner of fruits, from apples and tomatoes to grapes. A warning bell sounded with the realisation in the late 1970s that one of the country’s greatest red wine grape varieties, Touriga Nacional, was in danger of being abandoned in its native northern Portugal in favour of vine varieties that were easier to grow. A determined effort was made to rescue it from extinction and a full range of different clones of the variety was maintained. But this was just one variety. At the same time, according to Antonio Graca of Sogrape, a member of the official Portuguese vine variety protection body Porvid, “there was rampant erosion of our viticultural heritage. If we had kept on [just planting the vines that were easiest to grow], by 2025 we would have reduced the number of Portuguese vine varieties by 90 per cent”. Although for many years the Portuguese wine industry’s efforts were focused far more on the cellar than the vineyard, Portugal’s viticultural riches are starting to be appreciated. The national vine repository at Pegões now has examples of 65 recuperated national varieties with a further 190 in prospect. The team of vine curators will presumably be using the country’s rich heritage of 19th-century ampelographies, or directories of grape varieties, to help in their identification. And nowadays DNA analysis can help enormously too. Touriga Nacional, for example, does not seem to be related to any non-Portuguese variety and today is grown on a total of more than 7,000 hectares (17,500 acres) all over Portugal. Like Cabernet Sauvignon, its distinctive character seems to translate well in a wide range of different terroirs. Although it makes deep purple wine with the potential to age for decades, when young the wine is unusually floral, smelling of violets or, according to some Portuguese tasters, bergamot, the active ingredient in Earl Grey tea. It has long been one of the most admired of the many grape varieties blended into top quality port. In the old days, as elsewhere in Europe, vineyards were planted with a field blend of different varieties, but when Portuguese growers became more varietally aware, wines made exclusively from Touriga Nacional emerged from regions all over Portugal, with particularly good results in the Dão region. But in the next phase of Portuguese wine evolution it seems likely that the variety will increasingly be blended with other varieties. The nobility and strong character of Touriga Nacional has been too obvious for non-Portuguese vine growers to overlook, however. It is now grown in Spain, Argentina, Brazil, Greece, Israel, California, Washington state, Virginia, South Africa and especially Australia. The initial Touriga Nacional cuttings were almost certainly taken to South Africa and Australia centuries ago when early colonists’ ships were provisioned in Portugal en route. Such is the singularity and quality of Portugal’s own varieties that the country has remained admirably impervious to the wave of Cabernet- and Chardonnay-mania that engulfed so much of the rest of the wine world in the 1980s and 1990s. There are only just over 2,000 hectares of Cabernet Sauvignon in the entire country and fewer than 600 ha of Chardonnay. Syrah is the most planted international variety, but there are still fewer than 3,000 ha planted. I can strongly recommend the more authentically Portuguese likes of Trincadeira/Tinta Amarela, Baga, Touriga Franca or Alfrocheiro Preto among reds and the distinctive white wine grapes Arinto, Síria/Roupeiro, Fernão Pires/Maria Gomes. A bottle of Touriga Nacional 2008 DãoThe only significant imported vine variety is Spain’s Tempranillo, known in northern Portugal as Tinta Roriz and in Alentejo in the south (cork country) as Aragónez. The Spanish intruder is Portugal’s second most planted vine after the 18,500 ha of vineyard that is planted with the vine known variously as Castelão, João-de-Santarém and Periquita. This widely planted grape produces usefully friendly, fruity red that can be drunk young but can also make wines that are still delicious after five or even eight years. It is a characteristic of typical Portuguese red that it is relatively high in both tannin and acidity, and Portuguese whites tend to be no less distinctive, crisp and long-lived. The Atlantic climate seems to help retain freshness in the wines and for many years it was the Portuguese winemaking habit to emphasise the grapes’ relatively thick skins and high charge of tannins. This stylistic distinction may have hampered the progress of Portuguese wines on export markets in the past, but for a palate tired of the limited palette of international varieties, Portugal has much to offer. And Portugal’s talented new-wave winemakers are much more skilled at managing those tannins than their forebears. When the first new wave of Portuguese wines hit the market a decade ago, they fuelled a great swelling of national price and concomitant price rises that made them look overpriced outside Portugal. In a more sober marketplace, prices are looking a little more reasonable. Both reds and whites are well worth a look.
