21 Mar 2016 --- Breckenridge Brewery and Starr Hill Brewery are running it back with their second collaborative beer project. Whiteout, an imperial white IPA brewed with lemongrass from Virginia, debuts at Denver’s Collaboration Fest on Saturday, March 19th. Brewmasters Todd Usry of Breckenridge and Robbie O’Cain of Starr Hill developed the recipe and brewed it together last month at the Breckenridge production brewery in Littleton.
