Dry farming is a viticultural practice in which grapevines are grown without routine irrigation, relying on rainfall and water stored in the soil. It is used in many established wine regions where irrigation is restricted, unavailable or deliberately avoided. Dry farming requires suitable soils, climate, vine spacing, rootstock and vineyard management; it is not practical in every growing region.
Vines obtain water from rainfall and soil reserves. Growers manage soil structure, cover crops, cultivation, canopy and crop load to conserve moisture and reduce competition. Deep-rooted vines may access water stored below the surface, but rooting depth depends on soil, rootstock, vine age and site conditions.
Dry farming can reduce irrigation demand and may encourage vines to adapt to local water availability. It does not automatically produce more concentrated or higher-quality grapes. In drought conditions, severe water stress can reduce photosynthesis, stop ripening, damage vines and lower yields. Good dry farming depends on sustainable soil and water management.
Dry farming relies on rainfall and stored soil water without routine irrigation. Regulated deficit irrigation supplies controlled amounts of water at selected stages to manage vine growth and berry development. Both approaches aim to manage vine water status, but they are different practices.
Example: some old-vine vineyards in California, Spain and parts of Australia are dry-farmed where soil and rainfall conditions allow.
Chef’s note: dry-farmed does not automatically mean organic, biodynamic or superior wine. Evaluate the producer, site, vintage and finished wine.
