In 2008, Fetzer Vineyards redesigned its bottling process to use a more lightweight bottle by reducing the thickness of the glass and removing the "punt" or indentation at the base of the bottle. The result was to reduce the weight of each wine bottle from a little over 23 ounces to 16 ounces, for a 17% reduction in the amount of glass used per bottle. This reduced the overall glass usage by 2.176 tons In a year in which the company produced about 22 million bottles of wine. Reducing the weight of each bottle also reduced the amount of energy needed to produce it, the amount of fuel required to transport It throughout the supply chain, and the energy needed to landfill or recycle the bottle after consumption. The result was a 15 percent reduction in annual greenhouse gas emissions, or 3.000 tons of CO2 equivalents in the supply chain. Dr. Ann Thrupp, Fetzess sustainability manager at the time, was quoted as saying: "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."
