Among others, Andalusia (-19.9%, 889,000 hl), Catalonia (-22.6%, 2,545,000 hl) and Castile-La Mancha (-9.47%, 20,036,000 hl) suffered losses. Castilla-La Mancha nevertheless accounts for more than half of Spain's total wine and must yield of an estimated 37.3 mill. hl. Positive reports came mainly from Extremadura (+17.40%, 3,017,000 hl) and Navarre (+14.5%, 722,000 hl). Castile-Léon, the Basque Country and the Balearic and Canary Island groups were also able to harvest slightly more than last year.

The reasons for the low yields are likely to be, on the one hand, the intense heat wave that had the country in its grip for a long time, and on the other hand, the partly heavy rainfall that fell in the east of the country in mid-August which may also have led to reduced yields.
