Even though I prefer "beer nerd" I guess this description fits me:

...it was Sean Ziegler, pouring beers for Dogfish Head brewery at at the Big Beers, Belgians and Barleywines Festival Saturday, who told it. "Wine is like an art. Your always subject to nature," Ziegler said. "Beer is more like a science. Hence, the name beer geek. You can measure the color, the hops, the sweetness - and theoretically - if you can measure it, you can reproduce it over and over again." The predominately male crowd at Saturday's festival is part of a larger beer culture much different than the quantity guzzling, can crushing frat boys often associated with beer. These beer lovers crave knowledge about their favorite carbonated beverage. They seek out brews that are complex in color and flavor and do it through tasting, smelling, attending festivals, visiting breweries and cooking up their own concoctions. "There's not a beer I don't like, there's not a beer I won't taste, there's not a place with a brewery that I won't visit," said Chris Katechis of Oskar Blues Brewery, who was serving up Old Chub Scottish style ale among others. "Everything there is to know about beer, we want to know. What time the brewer wakes up and starts brewing - we want to know."
