PRWeek understands that Magners has issued creds around bringing in comms help for a large retained brief.
It is believed the work will be consumer-facing, with a strong experiential element.
The search comes as the cider industry continues to grow amid difficult times for other beverages, with the market showing 46 per cent growth between 2002 and 2011.
Leading this growth has been Magners, which this summer moved its digital and social media work into The Red Brick Road, which already handles its advertising.
The cider brand has gained the second largest share of the market, with 7.5 per cent, in the seven years since it was launched.
However, the market is becoming increasingly crowded, with the launch of Anheuser-Busch InBev’s Stella Artois’ Cidre last year one of a number of new entrants.
Magners had not responded to requests for a comment at the time of going to press.
Magners is owned by the C&C Group, which also owns Bulmers as well as non-cider brands including Tennent's.
