No, I'm not, thanks.
The craft beer/microbrew movement is relatively new. The Boston Beer Company, for example, started in 1984 and sold its first beer in 1985.
As they themselves put it, "In 1984, the American landscape was vastly different from what it is today. The only options for domestic beer were pale lagers from the mass market brewers. To find a flavorful, "better beer", there were only a handful of imports like Heineken and Beck's that were thought of as the only option for quality beer. American craft beers were virtually non-existent, or still in the basements and kitchens of a few spirited brewers. There were virtually no widely distributed micro brewed beers."
The problem, of course, is that you can't reverse the 50+ year legacy of prohibition on a dime. During Prohibition, the only way to get beer was to smuggle it in, or more often to make it yourself (badly), so the effect was that American beer tasted bad and had to be drunk very cold to be palatable; after prohibition ended, the only companies in a position to expand into the new beer market did so with the generic American-style lager that, again, had to be drunk very cold to be palatable.
By the time Sam Adams entered the market, Americans had gotten used to the idea that beer should be drunk at refrigerator temperature, not cellar temperature.
