San Juan
San Juan is the second most productive region of Argentina after Mendoza. Its territory is entirely included among the hills that precede the Andes mountain range. It is a semi-desert region, with a continental and very dry climate, where viticulture can only take place due to the presence of the San Juan and Jachal rivers and efficient irrigation systems, but also from the average high altitude at which the vineyards are located which mitigates local temperatures. Here the vines of European origin, such as Bonarda, Syrah, Cabernet, Malbec and Merlot for the red wines and Chardonnay, Sauvignon Blanc, Torrontés and Viognier for the whites, have found a thriving place for their vegetative growth. Within San Juan, three sub-regions can be distinguished, one more interesting than the other. The Pedernal Valley, known for the production of high quality wines, takes its name from the Spanish term used to indicate the flints of which its soils are rich, which limit the yield and growth of plants leading to the production of wines with more concentrated aromas and tannins. The Tullum Valley, on the other hand, is recognized for the production of dense and peppery Syrah rich in character and for its quality whites. Finally, the Valle di Zonda has as its characterizing element the strong wind of the same name Zonda which contributes both positively and negatively to viticulture: it protects from the risk of disease but at the same time hinders the growth of younger plants. The porous and rocky soils of this territory require the development of deep roots in order to reach the water necessary for their development, with the effect of producing grapes with a good concentration of sugars and tannins which will result in complex wines and structured.
