Chivas Brothers has finally unveiled its plans for Beefeater Gin.

The Pernod Ricard unit will launch a new-look bottle and global advertising campaign for the brand, which it inherited when Pernod bought Allied Domecq in 2005.

The "multi-million pound" ad campaign, entitled Forever London, builds on Beefeater's position as the only premium international London Dry Gin still distilled in the city.

Each execution is a collage of London images, including red London buses, the Houses of Parliament, black cabs and red telephone boxes.

The campaign has been developed to support the brand in its key markets, including Spain and the US. Initially, it will contain five print and two outdoor executions, all using the tagline 'Forever London since 1820'.

"There were a number of issues facing the brand in 2005," said Chivas international marketing director Martin Riley.

"The image of the brand overall was declining, except in its key market of Spain. The packaging lacked premium cues and wasn't doing justice to the liquid in the bottle and there was a lack of consistent advertising in key markets.

The Forever London will make its debut in Spain next month and will be rolled out to other markets in March and April

Beefeater sales volumes rose 5% during the six months to 31 December thanks to a recovery in Spain and rising sales in the UK, France and Russia.

Riley added: "Beefeater is an international brand and has the potential to be a really strong global brand."
