'''Salta''' is a wine producing province in north-western [[Argentina]], internationally recognised for its extreme high-altitude vineyards and distinctive wine styles. [[Viticulture]] is concentrated in the [[Calchaquí Valleys]], where some of the world’s highest commercial vineyards are located, shaping wines of marked aromatic intensity, freshness and structure.<ref>Robinson | '''Salta''' is a wine producing province in north-western [[Argentina]], internationally recognised for its extreme high-altitude vineyards and distinctive wine styles.

[[Salta]] lies along the eastern [[slopes]] of the [[Andes]] and is characterised by arid conditions, intense sunlight and significant diurnal temperature variation. Vineyards are typically planted at elevations ranging from approximately 1,500 to over 3,000 metres above sea level, with sites around Cafayate among the most prominent.<ref>Johnson | [[Salta]] lies along the eastern [[slopes]] of the [[Andes]] and is characterised by arid conditions, intense sunlight and significant diurnal temperature variation.

The combination of high altitude, strong ultraviolet radiation and cool nights slows grape maturation, preserves acidity and enhances phenolic and aromatic development. Low rainfall reduces disease pressure, making irrigation essential for vineyard management.<ref>Jackson, ''Wine Science'', Academic Press, 2020 | The combination of high altitude, strong ultraviolet radiation and cool nights slows grape maturation, preserves acidity and enhances phenolic and aromatic development.

High-altitude viticulture in Salta presents both advantages and challenges. Thick [[grape skins]], resulting from increased UV exposure, contribute to colour intensity and tannin concentration in red wines, while white varieties develop pronounced aromatic profiles. Frost risk, wind exposure and water availability are key factors in site selection and vineyard design.<ref>OIV, “High-altitude viticulture”.</ref> | High-altitude viticulture in Salta presents both advantages and challenges.

Traditional trellising systems and careful [[canopy management]] are used to protect fruit from excessive sun exposure while maintaining airflow. Despite harsh conditions, vine longevity can be high due to the dry climate and reduced [[fungal pressure]].<ref>Winkler | Traditional trellising systems and careful [[canopy management]] are used to protect fruit from excessive sun exposure while maintaining airflow.

Salta is best known for [[Torrontés Riojano]], Argentina’s flagship aromatic [[white]] variety. In the Calchaquí Valleys, [[Torrontés]] produces intensely perfumed wines with floral, citrus and spice notes, typically dry and crisp rather than overtly sweet.<ref>Robinson, Harding & | Salta is best known for [[Torrontés Riojano]], Argentina’s flagship aromatic [[white]] variety.

Red varieties such as [[Malbec]], [[Cabernet Sauvignon]] and [[Tannat]] are also planted, yielding wines with deep [[colour]], firm structure and notable freshness despite full ripeness. [[Alcohol]] levels can be elevated, but [[acidity]] is generally well preserved due to altitude and cool night temperatures.<ref>Stevenson, ''The Sotheby’s Wine Encyclopedia'', 2011, ISBN 9780756686840.</ref> | Red varieties such as [[Malbec]], [[Cabernet Sauvignon]] and [[Tannat]] are also planted, yielding wines with deep [[colour]], firm structure and notable freshness despite full ripeness.
