ADVERTISEMENTThousands of people have turned out for one of Spain's most popular fiestas on Saturday — the annual Wine Battle.
The event takes place in Haro, in Spain's Rioja wine-growing region.
After an early morning Mass, participants throw around 70,000 litres of wine over each other.
Among the rules for those taking part: they must wear white, with a red sash, they may use wine-filled water pistols, garden sprayers or buckets, and at no point during the battle can they stop laughing and singing.
The event is held to celebrate Saint Peter and the region's plentiful wine output.
The festival draws a mostly younger crowd and some came from as far away as Australia.
