Recently finished this one, "Citizen Coors, An Amercian Dynasty" Very interesting to say the least. It is somewhat dated (2000) but still a fascinating read. I doubt it got much endorsement from the Coors family as there is a lot of "dirt".
For my fellow Canadians, I also just finished "Lager Heads" about the Labatt/Molson rivalry for surpemacy. Very informative.
