TBWA was awarded the work in partnership with its specialist shopper-marketing network, Integer Paris. The agencies will be responsible for boosting Campo Viejo's brand awareness outside its home country.
Advertising will focus on priority markets such as the UK and the US, and will run across TV, print, digital, retail and brand experience.
TBWA currently works with Pernod Ricard on brands including Absolut, Jameson, Martell, Kahlua, Royal Salute and Griffigna wines.
