In 2016, Jamie Williams cheered as his friends at Baere Brewing took home a bronze medal for their saison from the Great American Beer Festival. The next year, he cheered as his buddies at Our Mutual Friend Brewing won silver for Saison Trystero, a Brett beer. And then, to his delight, Williams's home-brew shop and brewery, Co-Brew, won its own bronze medal for the farmhouse saison it had entered in the GABF.

Three Denver breweries. Three medals. What would happen, Williams wondered, if the three breweries blended those three great beers together? Terrible idea, or brilliant?

It didn't matter. The three breweries gathered in January at Co-Brew, where they each brewed their own beer — with their own yeast strains — on the store's three small, twenty-gallon home-brewing systems. Then they blended the beers together and aged them for six months in a Chardonnay barrel.

"There's no other brewery in Denver that can brew three beers at a time," says Williams, who used his store's software to scale the recipes down to the right size. "So I think those guys had fun."

Last month, they bottled the beer. It's called Alloy, named after the word for a metal that is created by combining two or more  metals — or, in this case, medals.

The resulting beer, which went on sale in bottles on September 19, showcases the friendship between the three breweries, along with their house cultures and methodologies. Still, it tastes a little more like an OMF beer,  Williams acknowledges, because that brewery's yeast strain is much stronger than the others.
