The agency has been taken on by William Grant & Sons, a UK-based independent distiller, to handle the two brands.
The team begins work today led by Alec Samways, CEO of Splendid, and will aim to drive "trial and advocacy among the world’s curious individuals" of Hendrick's, and "reinforce The Balvenie’s status as the most handcrafted single malt Scotch whisky".
Samways said: "Working with William Grant gives us the opportunity to work with two exceptional brands. The briefs were made for us by client teams with whom we share a genuine passion and ambition. Both brands have such unique personalities – we’re as excited to explore the most unusual world of Hendrick’s as we are to learn and share the history and depth of The Balvenie."
David North, William Grant & Sons' global brand comms manager, said: "These are dream briefs for an agency and the Splendid Communications team demonstrated an affinity and impressive combination of creative ideas, strategic insight and smart thinking."
Splendid won the accounts following a competitive pitch process. William Grant also hired an agency for a wide-ranging UK brief last month.
