Denver Beer Co. is preparing to fly south this winter to start a new brewery with a new name. The company is expanding to Phoenix under the moniker Formation Brewing., said CEO Robert MacEachern. Construction is currently underway on an existing 10,000-square-foot building in an art district called Roosevelt Row. He anticipates it will open before the end of 2024. The expansion to Arizona enables the 13-year-old beer maker to build a regional presence while also helping grow the local craft beer scene there, MacEachern said.
