Non-union, non-pasteurized, soon to be made in Virginia

The AP reports here that Coors is going to build a new brewery at Elkton in Western Virginia, to start pumping out Coors Light.

Coors already has a facility at Elkton where they take "beer concentrate" and dilute it and package the beer and ship it to Eastern U.S., as explained at this site, which says: "If you ever saw the movie Smokey and the Bandit, you remember that the thin plot line was based on a race to deliver Coors from the western states. That's now an outdated scenario. Coors can sell its beer nationwide now, in part because it sends tank cars with "beer concentrate" (a specially-brewed, high-alcohol version of its standard beer) from Golden, Colorado to Rockingham County. Adding water and packaging in Virginia reduces the shipping costs substantially to the Northest and Middle Atlantic markets."

I've never quite figured out the "beer concentrate" aspect. In fact, I'm not even sure that the words "beer" and "concentrate" go together.
