Molson Coors Brewing Company has announced it's nearing the end of its multimillion-dollar project to update the Golden brewery's filtration, fermenting, and aging capabilities.

Molson Coors said the project will be completed in 2025. However, the facility is now operational, and the first beers have recently entered the market. It's equipped to make Coors Banquet, Coors Light, Miller Lite, Miller High Life, and Blue Moon Belgian White.

The 200,000-square-foot project, dubbed G150, will save an anticipated 80 million gallons of water each year and reduce energy use.

"The G150 project is an investment not only in the Coors Brewery and the Golden Valley, but Molson Coors' capabilities in the 21st century and beyond," said Molson Coors President and Chief Executive Officer Gavin Hattersley. "It's an investment we’re proud to make. Our plans are big at Molson Coors, and they’re rooted in the sort of projects that make this a world-class beverage company."

"Since breaking ground, over 2.4 million hours have gone into the project," the press release said. "It includes 200,000 square feet of space that stretches 1,000 feet end to end, nearly the length of three football fields. The brewery’s horizontal fermenters were replaced with more than 100 vertical tanks. Snaking through it all is 45 miles of piping and 150 miles of wire."

The routes for public tours will not change, so most people will not see the G150 Project modernization.

Coors Brewery opened in the 1800s. According to the website, Adolph Coors brought a brewer’s yeast from Germany to ferment his beers in Golden. Since then, the iconic spot has survived Prohibition, numerous wars, and the Great Depression.
