Pitches will take place at the end of the month. Sources said Grolsch plans to focus on digital advertising.
LBi previously handled Grolsch’s digital activity, but the relationship ended when the shop won the global Carlsberg digital brief in May.
Grolsch is not believed to have a digital agency of record in the UK.
Beattie McGuinness Bungay, which works on the UK ad account, is thought to be involved in the process.
A spokesman for Molson Coors declined to comment on the review.
