What pruning system is more commonly used in new, quality-focused vineyards in Argentina?

The cordon pruning system is favored in new, quality-focused vineyards in Argentina because it offers several advantages that align with modern vineyard management practices. This system involves training the vine to grow along a horizontal wire (the cordon), which allows for better exposure to sunlight and air circulation around the grape clusters. Improved sun exposure can enhance the ripening process and contribute to the development of more concentrated flavors in the grapes, which is particularly important for producing high-quality wines.

Additionally, the cordon system facilitates mechanization, making it easier to manage the vineyard and increasing efficiency in tasks such as harvesting. This system also allows for easier management of vine vigor and yield, giving growers more control over grape quality. Given the focus on quality in Argentina's emerging wine regions, particularly in areas known for premium wines like Mendoza, the adoption of the cordon pruning system reinforces the shift towards modern viticultural practices aimed at enhancing the overall quality of wine production.
