The agency won the integrated business after a pitch earlier this year. Iris will be responsible for handling the brand's global activity across TV, digital, press, retail, experiential and PR channels. A campaign, breaking in September, will target the over-50s market.
Iris also becomes Lindeman's UK agency across loyalty, CRM and market research. The brand already has a global presence in more than 50 countries around the world.
Rainey Kelly Campbell Roalfe/Y&R was the incumbent on the Lindeman's account but resigned it before the pitch.
Olimpia Luciano, the global brand director at Lindeman's, said: "The new integrated campaign will drive relevance with existing consumers, draw new consumers into the brand and grow its share of the new world wine markets."
