The brief, worth six figures, centres on building the beer brand through music and food events in the UK. The agency will use its PR and production departments to deliver a music strategy and produce an integrated events and publicity programme throughout 2015.
The comms for Estrella was previously handled in-house.
Lindsay Castling, brand manager at Estrella owner Instil Drinks Co, said: "House PR impressed us with its creative and commercial approach to our brief. Of all the agencies we saw, we felt confident that it understood our objectives and was best equipped to deliver the results we’re after."
Ginny Paton, managing director at House PR, said: "Estrella Galicia is an exciting win for the agency as the brief plays to so many of our strengths."
Estrella Galicia is Spain’s largest independent brewery and was founded in 1906. It has been exporting to the UK since 2012.
