INTRODUCTION TO GRAPE AND WINE-GROWING AND GEOMORPHOLOGY OF CHILE Chile is member of the group of countries collectively re- ferred to as Latin America. Its territory is described as being tri-continental, meaning it possesses land in the three conti- nental areas of America, Oceania and the Antarctic. Chile is located entirely in the southern Hemisphere (south of the parallel zero or Ecuador) and Western hemisphere (accord- ing to the Greenwich Meridian). This South American country is situated in the Western part of the Southern Cone, between parallels 17° 30’ SL.—the point where Chile, Perú and Bolivia converge--and 56°32’ SL—the southernmost point of the continent where Diego Ramirez islands are located. Transversally, Chile extends westward between meridian 66°33’ and 75°40’. It is located in the meridian 70 'L.0. time zone. The Chilean Antarctic territory begins approximately at paral- lel 62° S.L. and its surface extends westward from the merid- ian 53 'to 90' Greenwich. Chile’s oceanic territory extends further than the continental shelf and 12 nautical miles west of the furthermost island considered Chilean territory. A) San Félix and San Ambrosio (26° South Latitude) located 927 km from the mainland. B) Sala y Gómez located almost at the same latitude but 3,400 kms. From the south American mainland. C) Easter Island o "Rapa Nui” 3.760 km from the mainland. (27° South latitude). D) The Juan Fernández archipielago (30° south latitude) is constituted by Robinson Crusoe, Santa Clara and Alejandro Selkirk islands and is situated at 800 Kms from the mainland. CHILEAN MAP Fuente: Enciclopedia Encarta Chile is divided in fifteen political regions. It extends 4,360 kilometers from north to south and is approximately an av- erage of 185 kilometers wide. Chile is comprised of different geo-climatic regions and a variety of landscapes. Because of this, it boasts a range of different flora and fauna. The country is divided into three geographic and cultural zones: The Northern Zone, where the world’s driest desert is located, the Atacama Desert: the Central Zone where there 11 www.vinifera.cl is a Mediterranean climate that allows for diverse agricultur- al production, including fruits, cereals, vegetables, industrial crops and, of course, grapes; and, the Southern Zone, where uniQue flora and fauna exist due to the increased rainfall in the region. These climatic and geographic characteristics make Chile a country extraordinarily attractive not only for tourists but for viticulture. Wine production takes place in various regions of the country, though it is most concentrated in the central zone. Over the years other less-centrally located areas in both the North and South of the country have been discov- ered as being great for wine production. Chile has four Geographic Macroforms which vary according to the latitude and are key to understanding the country’s geo-climatic variations. Starting from east and extending into the western part of the country, the macroforms include: The Andes Mountains; the Intermediate Depression; the Coast Mountains; and, finally, the Coastal Plains. The country's most important mountain range is the Andes. Over the years the Andes region has taken more prominence in Chilean and South American viticulture. The Andes moun- tain range is approximately thirty million years old and is the world’s second biggest mountain range, following the Hima- layas. The Andes stretches along the western part of South 13 www.vinifera.cl America, from Guajira (Colombo-Venezuelan) to Cape Horn and the Antarctic where the range is called the “Antar- tandes”. In the North and the Central Zones of Chile, the Andes’ peaks can reach altitudes as high as 6,000 meters above the sea level. The world’s highest volcano Ojos del Salado, located in the Atacama region, is part of the Andes mountain range and is 6,891 meters above sea level. The Andes range also acts as a screen preventing both the entrance of the humid winds from Argentina into the Central Valley and the entrance of cooler temperatures from the Pacific Ocean into the western part of the South American continent. Moreover, the Andes allow for thermal oscillation. Some days there is a difference of 20°C between the day and night in this region. Grapes growing in the Andes accumulate sugar during the day while maintaining the natural acidity during the night. It is allowing for the grapes to have optimum fruit balance and for wine producers to generate high Quality wines. 15 www.vinifera.cl The Intermediate Depression is a basin area located between the Andes range and The Coastal Mountains. It is here where the major part of human settlements, agricultural activity (vineyards), and cattle industry are developed. The characteristics of this macroform vary according to the different regions of Chile. The depression extends from the pampas and deserts in the north to the basins and valleys (both transversal and longitudinal). Another geographic unit that influences the climatic and soil conditions of Chile is the Coastal range, which also plays an important role in local viticulture. This smaller mountain ranger begins 20 kilometers south of Arica city (extreme north) and falls steeply to the ocean. The range reappears further south, reaching an altitude of 2000 meters above the sea level. Close to the southern city of Concepción the name of this mountain range changes to Nahuelbuta range. The Coastal Range’s latitudinal extension creates a significant barrier, blocking the cold air masses from the Pacific Ocean and generating a Mediterranean condition eespecially in the Central Zone. The diverse mesoclimates and microclimates of Chile’s Central zone are optimal for viticulture. Additionally, this mountain range is perfect for growing Med- iterranean varieties of grapes because of its rolling hills and excellent slate soil in the Maule, Itata, and Bío-Bío regions. Finally, there are the Coastal Plains which stretch from the Pacific Ocean to the Coastal range. These plains have been created as a result of tectonic plate movement and the transgression (sea rises) and regression (when areas of sub- merged seafloor are exposed above the sea level) of the sea levels over the years. The Coastal plains of Northern Chile are limited in size due to the fact that the Coastal mountain range essentially cuts through these lands, creating headland. However, the plains are between 20 and 30 wide in the country’s Central Zone. Many economically important Chilean cities are located in this macroform, including IQuiQue, Valparaíso, Concepción, and Valdivia as well as other ports. There are even some coal deposits located in Chile’s coastal plains. In relation to viticulture, the Coastal Plains are strongly influ- enced by the Pacific Ocean and have colder climates in com- parison with the Central and the North Zone, making the region ideal for grape varieties that reQuire colder tempera- tures to express their characteristics fully. The same varieties that grow well in the Coastal Plains also flourish in the southern part of Chile with its colder climate. All this geomorphological information foregrounds the up- coming explanation of how these geographical characteris- tics shape Chile’s diverse climates and soils. This information also helps explain the variability and uniQueness of Chile’s current wine valleys. Chile’s territories, especially its macroform reliefs (detailed below), give it enormous potential in terms of its production of uniQue and highly diversified wines. Finally, these different macroforms allow winemaking ex- perts to organize Chile’s wine territory and determine the “Denomination of Origin” of the different wines according to the following the sectors: “Andes”, “Entrecordilleras” y “Costa.” 17 www.vinifera.cl 2.
