Shame, that. Beer has a history as rich as that of wine, and a varietal spread much larger. I'm not going to criticize you for your preferences, but I will point out the poorly-known fact that most well-known brands and types of beer, especially in America, are of one particular variety --the "light lager" style which is a poor representative of the world of beers out there. To put it in wine terms, american-style light lager is the beer equivalent of white zinfandel --it's not bad per se, it's just kinda there and it's a very poor representative of what good stuff is like.
Honestly, beers are so genuinely varied that there are numerous types that could be tasted side by side and you'd hardly believe they're the same type of product at all. Some are clear and golden, some a rich amber red, some are murky brown, some opaque black, with flavors ranging from malty semisweet to fruity (from dry to intensely sweet) to creamy to bitter and everything in between, and more besides. A cream stout tastes almost like chocolate milk, a lambic like fruit soda, and a whitbier like citrus. Most people don't know these varieties even exist. I knew very little about them myself before bartending school, and before working in a place that specialized in beer selection.
