The brief comes as Starbucks bolsters its 18-year relationship with Kraft Foods in the US. This includes firming up a contract to distribute its coffee products to retailers across the UK and Canada.
DraftFCB is believed to have won the brief through its place on the Kraft Foods roster in the US, leapfrogging other UK roster agencies, including JWT, to the brief.
Starbucks products are currently available in cafes across the UK, but this deal will be the first time that they will be available in supermarkets.
The Seattle-based Starbucks, whose annual turnover is $7.8 billion, was recently listed in tenth position in a Millward Brown UK survey for brands that are perceived to be growing in popularity fastest over 2006.
Starbucks and DraftFCB refused to comment on the win as Campaign went to press.
