It's like a water fight for grown-ups.

Revelers in the town of Haro in Spain's La Rioja region celebrated a traditional festival by dousing each other with red wine, the BBC reports.

Residents of the wine-producing region used more than 50,000 liters of wine in the wine battle, which is traditionally held on June 29.
