DEFINITION

Irrigation

Irrigation is the artificial application of water to vineyards to provide the necessary 25-35 inches of annual water in dry climates. It is used to manage vine health, growth and grape quality while preventing drought stress and improving yields. Drip irrigation is the most popular method for providing precise water directly to the roots, while wine growers in some regions carry out flood or surface irrigation.

Did you know? The best grapes often come from stressed vines. If consistently watered, a vine produces more leaves and bigger, lower quality grapes; while a restricted vine focuses its energy on making better fruit.
