Paraje Altamira: The Geographic Indication that transformed Argentina’s terroirs & 20 wines tasted

About 20 years ago, Argentina saw the first stirrings of what would become known as the ‘terroir revolution’. During this time, wineries began to carry out in-depth studies of their vineyards to gain a better understanding of the effect the local conditions had on their wines. This meant that it became useful for labels to state an exact place of origin, to indicate what drinkers might expect of the terroir-imbued character of the wines. In 1999, the National Institute of Viticulture of Argentina (NIV) began a programme of Geographic Indications (GI) based around existing political boundaries – namely provinces, departments and districts. However, those demarcations did not necessarily align with the natural boundaries responsible for lending wines their distinctive profiles.

At the time, you could put “ Mendoza , Argentina”, or maybe “ Uco Valley ”, but we knew that the Uco Valley has a range of diverse climates and soils, and so we started a study programme to gather information and knowledge that we’d never had before.’ During this process, Paraje Altamira GI was created, a milestone in the history of Argentinian wine – and one of the new and most exciting ‘grand crus’ in South America. The Paraje Altamira example ‘The work we did to create the Paraje Altamira GI was essential. We’d never studied the climate, soils and geological origins of a specific place in such detail, and we worked in partnership with distinguished experts and institutions,’ says Hervé Birnie-Scott, estate director at Terrazas de los Andes . The spur came in 2010, when the wineries Catena Zapata, Familia Zuccardi and Chandon (Terrazas de los Andes) invited the Universidad Nacional de Cuyo to run the research programme and present the results to the NIV. But there were further obstacles that needed to be resolved first. ‘Altamira had two issues that we had to deal with,’ says Sebastián Zuccardi . ‘ The name was registered as a trademark and we couldn’t use it. Also, it didn’t have any geographic boundaries; it was an area within the District of La Consulta (Department of San Carlos, Uco Valley). The quality of the vineyards had earned them their own name among the locals: “Altamira”. We all knew that we needed to start promoting the place so we commissioned the most detailed studies possible to show the NIV that the region had its own distinctive characteristics.’ The studies included soil mapping, geological information, satellite imagery and the assaying of hundreds of soil samples to show that the area studied – designated as ‘Altamira’ – shared a set of characteristics that differentiated it from neighbouring areas. This would allow a new GI border to be drawn up. It was then that the leaders of the initiative came up with the idea of adding ‘Paraje’ (a local term for settlement or village) to differentiate it from the trademark. Eventually, in 2013, the GI was approved and since 2014 it has been permitted to put the term on the labels of wines from the area.

Paraje Altamira is a village located in San Carlos, a department to the south of the Uco Valley. It encompasses 2,733ha of vineyards in the southern alluvial cone of the Tunuyán River. This is what lends the area its defining characteristic: heterogenous, stony soils rich in calcium carbonate. ‘Paraje Altamira is the highest part of the alluvial cone of the Tunuyán River and also the highest part of La Consulta,’ says the geophysicist and educator Guillermo Corona, the author of the book Geografía del Vino ('A Geography of Wine'). ‘The main difference between the two sectors is that in Altamira the stones coated in calcium carbonate are found closer to the surface, and so come into direct contact with the roots of the vines. That doesn’t happen in La Consulta, where the soils are deeper and are more sandy-loam based. The soils are the key factor, not the climate, because the slope is shallow and there’s not a great difference in height,’ he explains.

They’re planted at a height of between 975m and 1,097m, in dry conditions like the rest of the Mendoza, with a significant thermal amplitude; the temperatures plunge at night.’ Grape vines and other fruit have been grown here since the 20th century and were always famous for their quality. ‘A secondary factor is over a century of flood irrigation, which means that the soils have a greater amount of limestone on the surface. The vineyards planted in the last 20 years, in virgin soils, use drip irrigation in stonier soils. They also interact with the local flora,’ concludes Corona. High-quality wines ‘The historic quality of the grapes and wines in this area was what motivated us to work on the creation of the GI,’ says Birnie-Scott. ‘Terrazas de los Andes regards it as a modern classic of the Uco Valley. Classic in the sense that it’s balanced and harmonious, delivering intensity and complex aromatic profiles with dark fruit and lots of spice, power and precise tannins in the mouth – and excellent ageing potential.’ Leading winemakers in the area include Sebastián Zuccardi and his Finca Piedra Infinita vineyard whose 38ha are divided into 36 parcels due to the vast range of soil types found at the foot of the Andes. ‘The Malbecs stand out for their red and blue fruit, but the most important quality is the chalky texture provided by the white layer of limestone material that covers the stones, which define the place’s elegant character,’ he says. Although the greatest amount of surface area is dedicated to Malbec, ‘historically the Cabernet Sauvignon , Chardonnay and Semillon have always stood out and account for the oldest vineyards in Paraje Altamira. New plantings of Cabernet Franc are another trend that is seeing really excellent results,’ says Andrea Ferreyra, head oenologist at La Celia, which has been in the region for over a century.

Ten years after the original studies, some producers are exploring the possibility of future subdivisions, now that they have better knowledge of the soil profiles, exposure and altitude. Whatever happens to Paraje Altamira in the future, it is important to note how its initial appearance changed the Argentinian wine scene. The 2013 initiative established the minimum requirements for the GIs that followed, such as its neighbour Pampa El Cepillo, Los Chacayes and San Pablo in Tunuyán, and several more across the rest of Argentina. It has also inspired some of the existing GIs to implement new studies and draw up fresh maps for their own terroirs.
