It seems to me that more people, younger and older, are leaning more toward quality brands of beer or wine, just from personal observation.
I just bought stock in STZ and someone on that board said they heard they might want to buy out SAM. That would be fine with me, good brand! Have no idea if it's true or not, though, so consider the source.
I feel this definitely helps brewers like Boston Beer. American consumers continue to move toward better quality in many aspects of their lives...along with the desire to try new things. Perhaps these same consumers are the ones that are moving away from the Millers, Buds, and other piss in a can brews.
