The company is a division of C&C Group, the Ireland and UK-based manufacturer, marketer and distributor of brands including Magners cider, Gaymers cider, Blackthorn cider and Tennent’s lager.
The drinks company joins eight existing member companies, including Carlsberg, Diageo and Pernod Ricard, who either distribute or own the majority of the brands sold in the UK.
Seymour Fortescue, chairman of the Portman Group, said: ‘By joining the Portman Group, Magners GB is demonstrating its serious commitment to marketing its products responsibly and in a way that does not encourage excessive or underage drinking.’
Gordon Johncox, managing director of Magners GB, added: ‘Responsible drinking is a key objective for the drinks trade and we recognise that more still needs to be done to educate consumers.
‘By becoming members of the Portman Group, we can collectively continue to drive awareness of these issues and have valuable input when it comes to framing alcohol policy,’ Johncox concluded.
