The agency will also provide social media support for the Staffordshire-based brewer, which supplies craft beers to pubs and restaurants across the UK.
Andrew Taylor, director at Freedom Brewery, said: "We have expanded the brewery and tripled capacity in the past 12 months to cope with demand. We have a compelling story to tell and we are confident LightBrigade will do that job for us."
Alan Twigg, managing director of LightBrigade, told PRWeek: "We will use product placement, experiential and stunts in the retail and hospitality space as well as lifestyle media relations, social seeding and blogger outreach. We are also keen to pursue brand partnerships both in and out of the home."
