Rabbit Hole Distillery has earned the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR certification. It is among the first-ever distilleries to receive the certification, standing in the top 25% of U.S. facilities for energy efficiency and performance. Rabbit Hole Distillery, part of the Kentucky Bourbon Trail, operates from its state-of-the-art distillery in Louisville. Rabbit Hole’s sustainability initiatives have significantly improved the distillery’s operational efficiency, resulting in reduced water and energy usage, the company said. It installed high-efficiency LED lighting throughout its facilities, reduced steam usage and increased the amount of setback in the cooker, utilized reclaimed water in operations including cooker cooling water and invested in technology and equipment to ensure high operational efficiency, among examples. ENERGY STAR was introduced by the EPA in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency.
