It doesn't. We're pretty savvy on beer now and the microbrew scene has a mind boggling variety and optimum serving temps, preferred glass or mug type, bottled vs draft, etc ad nauseum.
What's sad is that once upon a time our regional macro lagers were pretty darned good products. Hamms, Old Style, Schlitz, Miller, Schaffer, Coors, PBR, Hudepohl, etc, were darned good lagers but the gods off Wallstreet decided more money could be made by using cheaper diluents like rice and corn and quality be damned and the beer scene in the US went to hell in the 70's and 80's but that prompted the microbrew revolution where we went from worst to first.
