The Langguth Wines-owned brand will reintroduce its range of classic wines to the UK market with new packaging.
Agency Be Communications will handle in-store activity, PR, sponsorship and events.
Angela Farmer, director, Be Communications, said: "The Blue Nun brand has a strong heritage and holds a fascination and intrigue for many consumers, young and old.
"We plan to tap into this latent affection and take the brand forward without alienating the existing fans of the brand."
The relaunch is scheduled for the week of 21 February, with the products expected to hit stores at the beginning of March.
