In the 1970s, yields were reported as surpassing 22 tons per acre, a sharp contrast to the average yields in premium wine regions such as Bordeaux and Napa Valley of 2 to 5 tons an acre.[1] As the Argentine wine industry continues to grow in the 21st century, several related viticultural trends will involve improvements in irrigation, yield control, canopy management and the construction of more winemaking facilities closer to the vineyards.[2]
