Brown-Forman has upped the environmental credentials for its Californian wine brand Fetzer Vineyards.

The wine and spirits group said yesterday (14 October) that it will introduce lighter weight bottles across its entire like of Fetzer wines. The new bottles will reduce glass usage at Fetzer by 16%, Brown-Forman said.

The change in Fetzer's wine bottles will continue with both 750ml and 1.5-litre sizes and all varietals. On average, the wine brand's bottles will move from 20.3oz to 17oz. In all, more than 23m bottles of wine will be replaced in the programme.

"Fetzer's pioneering efforts at being the 'Earth-friendly wine' is more than just an advertising tagline, it's a philosophy that permeates everything we do at the winery," said Ann Thrupp, manager of sustainability at Fetzer. "Lightweighting our bottle is a double-bottom line innovation — good for the environment and for efficient operations — that supports our goal of being a sustainable business."

Fetzer has been a strong advocate of environmentally-friendly farming over the last 20 years. The company uses recycled materials in all packaging — wine bottles are made from 35% recycled glass on average and box partitions use 100% recycled material — and has reduced waste to landfills by 95% since 1990.
