The company said the design was “heightened and slimlined” and described the shape as “feminine” and more suited to fit in a fridge door.
It is being backed by a £1 million marketing campaign including a new off-trade POS toolkit.
Chris Lock, Baileys’ western European category marketing director, said: “Our new design stays true to Baileys’ iconic heritage, in a contemporary and stylish way.
“We are confident that this, coupled with the same great tasting liquid, will not only have more impact on shelf, but also affirm Baileys' position as a modern drink for the modern woman.
“Baileys is the original cream liqueur, and enjoys a 78.2% share of the cream liqueur market, which is why it is vital that we continue to drive and shape the category with exciting news and innovation.”
