Sagres is to be one of the official sponsors for next year's Rock-in-Rio Lisboa festival.

The Portuguese beer brand, owned by Central de Cervejas e Bebidas, will invest around €1m (US$1.2m) in next year's festival after successfully sponsoring the event in 2004.

Along with Portuguese bank Millennium bcp, Sumol/7UP, Toyota and Vodafone, Sagres will be present at the festival, to be held in Lisbon on 26 and 27 May, and 2, 3 and 4 June next year.
