To weigh in on the whole Bud Light debate, I think the whole "flavored water" thing is accurate. It's really the difference, as IP notes, between a fast food hamburger and a great steak. It's a quality issue, but it's also an acquired taste issue.
I think IP's suggestions are spot on. It's all about acquiring the taste. I remember the first time I tried light beer in my teenage years. I thought all light beers were bitter and that Coors, Bud, and Miller were all steps up from Natty, Busch, and other such luminaries as Steel Reserve.
However, after drinking them for a while, your taste buds adjusted, and you were ready for something new.
Then I remember drinking my first IPA, a Smutty Nose IPA in a bar that my girlfriend (now wife) works at. They gave me free beer there, so I'd just randomly try whatever they had on tap. I was shocked by the bitterness, but found myself the next time I was there jonesing for more.
I think that IP's recommendations are pretty perfect for IPAs, the only thing I'd qualify it with is that while they are my favorite types of beers, I have a lot of beer snob friends who don't like them that much. So I'd also recommend to KG's Knees to expand out in other directions.
I think the most approachable beer style is likely the wheat beer. They are all over the place, and often have other flavorings in them to make the adjustment easier.
Two very easy ones to start with that have flavoring are Blue Moon and Sam Adams's Summer Ale. Blue Moon has orange and coriander and Sam Adams has lemon zest and grains of paradise (a peppery spice).
From there, you could go to something like Harpoon's UFO Hefeweizen or Troeg's Dreamweaver.
As you get more sophisticated with them, hitting ones like
Weihenstephaner Hefeweissbier, Franziskaner Hefe-Weisse, and even Sierra Nevada's Kellerweis, you'll get slightly funkier notes coming in from a more Belgian style of yeast. If you like that, you'll be primed to start some Belgian Tripels down the line.
Again, I don't think every beer style is for everyone. Personally, I'm not a huge fan of stouts and porters (though I do appreciate a good one). However, I do think there is a style of good beer out there for everyone.
For my birthday last year we had a beer tasting for about 25 people where we sampled a bunch of exotic beers. And even my friends who stick to the classic domestics ended up finding at least a few microbrew beers that they really liked.
