In some cases, irrigation is required, and more frequent droughts are a key concern for yield and fruit quality . Water stress reduces shoot growth and berry size, and increases tannin and anthocyanin content . However, controlled water stress produces positive impacts on wine quality, increasing skin phenolic compounds . The level of stress will depend on soil type, texture and organic matter content . Increases in water demands with potential negative effects from increased soil salinity are among the most common effects of climate change in irrigated regions  .
