In terms of quality, the wines of Argentina have come a long way in a short time, as the range represented at this year's fair attests. The Mendoza region remains the most productive in the country, although others, notably Patagonia, are showing great promise. The area of Mendoza under vine is greater than that planted across the whole of Australia and New Zealand combined. Among the wineries from Mendoza participating in the fair are Barberis Hno, Latinfina, Las Piedras Pura Vid, Bodega y Vinedos and Renacer . Another exhibitor, Los Domados, is one of a number of Argentine wineries moving towards organic or biodynamic methods of production, and places a strong emphasis on caring for the vines with minimal soil interference. 'The vineyards are cultivated using techniques which have a minimum impact on the environment and, in the short-term, organic certification will be acquired,' says Los Domados' agronomist Daniel Spigatin. Owner Fernando Spigatin likens wine making to another great Argentinian skill practised in the area, horse taming, and the wines are named after Spanish words for different types of crossbreeds - Rosillo, Tobiano, Lobuno, Zaino, Gateado, and Alazan. The Domados vineyards cultivate malbec, still Argentina's signature red grape; cabernet sauvignon, merlot, chardonnay, pinot noir and semillon. One point of interest on the stand of Patagonia's Bodega Patritti is the innovative 'cork tester' the company has developed. It consists of a self-adhesive band around the neck of the bottle beneath a shortened capsule. By peeling it back, it is possible to monitor the evolution of the cork over time and to get a more precise idea of how long the bottle can be kept. In addition to individual wineries, larger groups are also participating. Munoz de Toro Wines has vineyards in Patagonia, Pampas, and La Rioja, and in Chile's Casablanca Valley. San Huberto Wines already has a presence in Asia. In addition to having vineyards in Mendoza and La Rioja, it has opened a winery in Huailai on the mainland, one of the first Argentinian companies to take such a step.
