Heaven Hill Distillery filled its nine millionth bourbon barrel, the only independent distillery company to hit that benchmark.

The distillery is now currently aging more than 1.8 million barrels across 63 warehouses, currently producing 1,300 barrels per day, according to a news release.

The nine millionth barrel will be put up to age in Rickhouse Y, where it will be displayed amongst Heaven Hill’s other milestone barrels.

“In a year defined by teamwork and perseverance, today we celebrate another historic Heaven Hill milestone as we fill the nine millionth barrel of Bourbon,” Max L. Shapira, President, Heaven Hill, said. “This nine millionth barrel, a rare achievement in the industry, is a testament to Heaven Hill’s commitment to quality and consistency since 1935.”
