Why would it be a bad thing?
Well, that would depend upon who decides what defines a micro brewed beer, and what those who are in power consider to be artisanal beer. For example: Bareknuckle Stout from A-B isn't really a microbrew, but maybe the folks at Sheraton may think otherwise. Also, there could be a strong market placement strategy from the big bucks being coughed up by the market hogs producing swill to influence these decisions. Do you think of A-B when you think of artisanal brewing, or do you think of the likes of Avery, Stone, Three Floyds, 21ts Amendment, Russian River, Lagunitas, etc? All depends on the perspective of the consumer. To the execs of Sheraton, anything that isn't a pale anemic american lager might be thought of as a artisanal microbrewed beer, even if it comes from one of the big fellas. See what my concerns are now?
