A few brief words on the back label of a bottle I opened recently caught my attention: “…vineyard with ungrafted pre-phylloxera Bordeaux rootstock.” But the wine wasn’t from Bordeaux, it was from Chile – Los Vascos’ Cabernet Sauvignon (Majestic, £9.99) – and the phylloxera bug hit Bordeaux in the 1870s. So, what’s the link between Bordeaux and Chile, was the vineyard really planted almost 150 years ago before phylloxera and what does it mean that the rootstocks are ungrafted?
To start answering those questions, we need to turn the clock back to around 1850 when a number of wealthy Chileans began to travel to Europe. Not only did they enjoy the sights, they also experienced some of its fine wines, which were very different from those available in Chile at the time.
One visitor was so impressed, he imported a selection of vine varieties from Bordeaux and hired a French winemaker to make his wine for him. This, of course, was some 20 years before France’s phylloxera infestation, and so no-one had even thought about the need to graft vines to combat the disease.
What is grafting? It involves planting a vine root in the ground that is resistant to phylloxera (or whatever pest you’re trying to protect against) and then connecting your chosen non-resistant vine (eg Cabernet Sauvignon, Chardonnay or almost any of the other varieties we know and love) to it. It is now universally accepted as the best method of protecting against phylloxera, for which there is no known cure.
Chile has been lucky – today it’s one of the few wine producing countries that remains free of this particular pest and so most of its vines are ungrafted.
But, back to the wine – the Los Vascos Cabernet Sauvignon. My wife, Hilary’s first comment was that wine tasted ‘more Old World than New’ and I know what she meant. This was a wine made in quite a restrained, elegant style without lots of the overt fruit flavours found in many New World wines. The reason for this probably lies in the fact that the estate is managed by Domaines Barons de Rothschild of Château Lafite fame; the lean Bordeaux influence certainly shows through and maintains a link to that region now dating back almost 170 years.
