The brand currently works with Fulham-based R&R Teamwork. It is one of the four agencies pitching.
Casella Wines senior brand manager Keith Fisken said it would continue to work with R&R Teamwork 'as a key strategic partner for the UK market', regardless of the outcome of the pitch.
Separately, Casella recently appointed Kate Veness as global comms manager. Veness is based in Australia but has responsibility for the UK market. She was formerly an account director at Manning Selvage & Lee.
