The amount of precipitation required in viticulture also depends on the soil conditions, such as water discharge and Water storage capacity dependent. The annual lower limit is at least 200 mm of rainfall, for quality viticulture there is an average of 500 mm, in warmer climate with high evaporation 750 mm required.

Rainfall - thunderstorm and rain

Provided that the soil conditions are right, there is no upper limit, because even more than 1,500 mm can be handled within a short time, especially in hot areas. However, the time of precipitation in the growth cycle his. A heavy rain just before vintage, especially after prolonged drought, can cause the grapes to swell and the content of sugar. acids and flavorings dilute. An artificial one irrigation is regulated differently within the EU in terms of country responsibility, mostly in terms of wine law.
