The economics of dry farming are a key consideration in relation to grape yields and prices. Dry farming wine grapes depend on residual soil moisture to meet the water requirements for grape vine growth and berry development (Chatterton, 196). Even in California’s dry Mediterranean climate, the water retained in soils from winter rains can be sufficient to support grape production throughout the growing season without supplemental irrigation. Dry farming techniques can improve grape and wine quality. Many growers have said that they trade quantity for quality when dry farming.

Tablas Creek Vineyard in Paso Robles believes that their dry-farmed berries are essential to the balance and expression of their wines. Dry farming can also have significant positive impacts on the environment and improve the sustainability of vineyards. By not irrigating, dry farmers reduce the water footprint of the vineyard.

If vineyards can conserve fresh water, not only will they be contributing to water conservation, but also reducing their dependency on a highly demanded resource, particularly in areas of groundwater overdraft (Hargreaves & Mary, 109).
