It is still brewed with Rocky Mountain Spring Water.
They changed it back in the 80's when they tried to expand to the east coast and built a canning plant in Virginia (as I recall) where the water was an exact match to the water in Golden.
They bought the water rights and renamed the location Rocky Mountain.
Then they engineered and bult glass lined refrigerated rail cars to transport the beer concentrate and can it at the new location.
Hence the slogan change.
Banquet is brewed at 15 to 17% alcohol content before it is cut with water before sending it through the tax meters. I learned this when I was in the Coors network and got to spend 3 days at the brewery (there was still only one) for training.
I even partied with the Coors family a couple times, attended a Superbowl with the, yada, yada, yada.
But there have been a few mergers since then and now all of their other brands are brewed at former Miller breweries under the corporate banner of Miller-Coors.
The Coors mystique was a real thing, and there was a lot of Smokey and The Bandit kinds of smuggling going on back in the 70's.
