I wonder if Coors still makes their beer into a syrup concentrate which they ship in big trucks from Golden, Colorado. They called it “dewatering.” Their bottlers mixed the syrup back with water and carbonation locally.
I thought pure mountain water was part of their "mystique".
When Coors had their brewery in Memphis, they would brew Coors Light (for export only since Coors sold in the states had to use Rocky Mountain spring water) double strength and cut it with water when canning. IDK about the Coors they shipped in. I imagine it was the same. FWIW, Memphis brewed Coors beat out the Colorado stuff in taste tests. We have great lager beer water. Also, the double strength stuff from the layering tanks was great. I wish they would’ve sold that.
