SIBA, the Society of Independent Brewers, was established in 1980 to represent the interests of the growing number of independent breweries in Britain. SIBA's 'Assured Independent British Craft Brewer' seal can only be used by British breweries who are fully independent, relatively small, and brewing quality beer. SIBA currently represents more than 750 independent craft breweries and our vision is ‘to deliver the future of British beer as the voice of British independent brewing'.
