En la producción del vino hay muchos factores ambientales que intervienen, tales como la calidad del suelo y el clima. La viticultura estudia la adaptabilidad de la vid a distintos tipos de terruño, es decir, las cuales, en general, no suelen verse propiciadas por las zonas extremas.

No obstante, toda regla tiene su excepción y Viñedos Villaseñor la encontró en Chile al estudiar, plantar, cosechar y vinificar el vino más austral, proveniente de la Décima Región de Los Lagos, Comuna de Cochamó, sector del Lago Tagua Tagua.

Las condiciones climáticas del lugar se caracterizan por una alta pluviosidad distribuida durante todo el año (entre 2000 y 2500 mm. promedio anuales) y durante septiembre-marzo las temperaturas máximas medias varían entre 16 y 20 °C y la mínima media entre 4 y 9 °C.

Aunque el sector donde se produce el Pinot Noir Puelo-Patagonia de Viñedos Villaseñor posee condiciones climáticas muy favorables, la producción de vinos en este sector debe ser cuidadosamente monitoreada. La uva se maneja manualmente y las plagas, dadas las condiciones del lugar, son casi inexistentes. Además, estos viñedos no poseen ninguna estructura formal de riego y solo se abastecen con el agua almacenada en el suelo durante la temporada. Finalmente, estas plantas son mínimamente intervenidas, ya que no se realizan labores vitivinícolas como raleo, deshojes y desbrotes durante la temporada.

La decisión de plantar en Puelo se debe, en primer lugar, al deseo de diversificar la oferta de vino chileno, cuyas plantaciones se encuentras concentradas en 90% entre las regiones V, VI, VII y Metropolitana.

There are many environmental factors involved in wine production, such as soil quality and climate. The viticulture studies the adaptability of the vine to different types of terroir, that is to say, which, in general, are not usually supported by the extreme zones.

However, every rule has its exception and Villaseñor Vineyard found it in Southern Chile when studying, planting, harvesting and vinifying the southernmost wine from the X Region of Los Lagos, Cochamó Disctrict, within the Tagua Tagua Lake zone.

The climatic conditions of the region are characterized by a high rainfall distributed throughout the year (between 2000 and 2500 mm annual average) and during September-March the average maximum temperatures vary between 16 and 20 ° C and the minimum does it between 4 and 9 ° C.

Although the lot from which Puelo-Patagonia Pinot Noir is produced has very favorable climatic conditions, the production of wines in this sector must be carefully monitored. The grapes are handled manually and the pests, given the conditions of the place, are almost nonexistent. In addition, these vineyards do not have any formal irrigation structure and are only supplied with the water stored in the soil during the season. Finally, these plants are minimally intervened, since no winemaking tasks such as thinning, defoliation and debris are carried out during the season.

The decision of planting in Puelo is due, in the first place, to the desire of diversifying the supply of Chilean wine, whose plantations are concentrated in 90% between regions V, VI, VII and the Metropolitan Region.

En segundo lugar, los efectos del cambio climático apuntan a un aumento de 6,4 °C en la temperatura promedio, mientras que la disponibilidad de agua podría variar hasta un 40 % en escorrentía. En cuanto a la luz UV, para el año 2050 se proyecta un retorno del agujero de la capa de ozono en la Antártida a su tamaño de 1980. Estos cambios climáticos podrían afectar factores de alta relevancia organoléptica en uvas y vinos, tales como el contenido de azúcar (y consecuentemente alcohol), así como modificaciones en la síntesis de compuestos fenólicos, responsables del color, aroma, astringencia y amargor de las uvas y vinos. De esta forma, la búsqueda de terroirs inexplorados o más extremos se vuelve una necesidad. 

En comparación con los vinos Pinot Noir provenientes de la zona central, las condiciones climáticas del lugar de Puelo-Patagonia permiten producir vinos livianos en boca, con una alta acidez (7,5-8,5 g/L), baja graduación alcohólica (11.5% v/v) y alto potencial aromático proveniente específicamente de la materia prima, la cual es producida bajo condiciones térmicas promedios comparativamente más bajas que la zona central, lo que permite la conservación de compuestos responsables del aroma y del sabor. Lo anterior, sumado al suelo proveniente de ceniza volcánica, hacen que el vino muestre características rústicas y distintivas, propias de la increíble Patagonia.

Second, the effects of climate change point out to an increase of 6.4 ° C in the average temperature, while the availability of water could vary up to 40% in runoff. Regarding UV light, by the year 2050 a return of the ozone hole in Antarctica to its 1980 size is projected. These climatic changes could affect factors of high organoleptic relevance in grapes and wines, such as the content of sugar (and consequently alcohol), as well as modifications in the synthesis of phenolic compounds, responsible for the color, aroma, astringency and bitterness of grapes and wines. In this way, the search for unexplored or more extreme terroirs becomes a necessity.

Compared with Pinot Noir wines from Chilean’s Central Region, the climatic conditions of Patagonia allows to produce light wines in the mouth, with a high acidity (7.5-8.5 g / L), low alcohol content (11.5% v / v) and high aromatic potential, specifically coming from the raw material produced under average thermal conditions comparatively lower than the Central Region. All of this enhances the conservation of compounds responsible for aroma and flavor. The above, added to the soil derived from volcanic ash, make the wine show rustic and distinctive characteristics, typical of the incredible Patagonia.
