The World's Most Refreshing Beer is made using a unique frost-brewing process that locks in a taste as cold as the Rockies. Coors Light has been delivering the ultimate in cold refreshment ever since it launched in 1978. First lagered below freezing for a crisp taste, it is then filtered cold for a brilliant, bright appearance. Finally, it is cold bottled, at the peak of freshness, to ensure that every Coors Light starts cold and refreshing and ends the same way.,
