Believe it or not, we're not here to make fun of what you drink - we all started where you're at now. But if you're really looking for a way in, you best bet is to start by just drinking better beer. Here's Hoosier Beer Geek's list of five proven and readily available "gateway" craft beers to make the adjustment as easy as possible:
A Beer Geek alternative to Budweiser, Miller, or Coors:
Brooklyn Lager - If you've tried craft beer before you may have been struck with how different it tastes to the beers you grew up on. With Brooklyn Lager you won't have to worry about that - it's the same Lager style beer you grew up on, except with a fuller, more flavorful taste.

A Beer Geek alternative to Guinness:
Goose Island Oatmeal Stout - If you're a fan of the roasty flavors of Guinness, other beers in the stout family might be right up your alley.
Goose Island's Oatmeal Stout is a nice second step into the stout family - the same sort of roasty flavors you'll get from a Guinness, with the addition of oatmeal to the beer to give it a little more heft. Don't worry, this isn't the slimy soupy stuff of breakfast - the oatmeal used is (usually) no more that 5% of the total composition of the beer. You'll notice that the beer has more body, but you probably wouldn't know it came from oatmeal if it didn't say so on the label.

A Beer Geek Alternative to Blue Moon:
Bell's Oberon - If you're drinking Blue Moon, you've already made a step towards beers with a hint more spice and fruit flavors. Bell's Oberon is a light and crisp ale with hints of orange and wheat. Oberon is a seasonal beer, available from late March through October, and is a fantastic summer day companion.

A Beer Geek Alternative to Killian's:
Rogue American Amber - Killian's drinkers have already taken a deliberate step away from the big three American lagers (Bud, Miller, and Coors) toward a beer with a bit more taste. But you can take an even bigger step with Rogue's American Amber - a beer brewed in Oregon. Rogue's beer has even bolder amber flavors, features hints of coffee, and finishes clean and refreshing.

A Beer Geek Alternative to Newcastle:
He'Brew Messiah Bold - As with the other beers on this list, Messiah Bold is a fuller flavored beer. You'll experience full balance flavors - fuller roasty malts, a slight hint of nut, chocolate, and caramel, and a little bit of a bitter bite on the back end from the use of hops to balance out the beer.

No one would claim that the beers listed above are the best beers in the world. But craft beer aficionados would claim that they are much better than your everyday brew. By being stylistically familiar to what you currently drink, they can serve as a bridge into the bigger Craft Beer world. Craft beer is about fuller flavors, bigger mouthfeels, and stronger scents. With a proper start we're confident you'll be a craft beer geek in no time.
