Real talk incoming. I have to disagree on the subject of Tecate - it isn't really too different from Budweiser/Corona/Coors. It's a Mexican macro lager, and those aren't significantly different from American macro lagers. They have much of the same watered down flavor, which comes from the adjunct malts (corn instead of barley) and the absence of complex roasted malts or really any hop character. Also, while Blue Moon is good (especially for people new to craft beer), compared to typical craft beer Blue Moon goes down like water xD; it's 5.4% abv, whereas beer styles like the imperial IPA and imperial stout that many craft beer drinkers love regularly clock in at 10% abv and higher. However, all that said, Blue Moon is good and it is an excellent starting point for someone who has only ever tried macro lagers. I would recommend giving Blue Moon a try. If you like it, PM me or VM me and I'll give you more recommendations!
Also, N, I have to completely disagree with you on both of your points D: European beer being godly and American beer being awful is a massive misconception that many people have. But in truth, having lived in Europe, there is bad European beer just like there is bad American beer. There is probably less bad European beer than there is bad American beer. But there is plenty of amazing craft beer in America, and American craft breweries tend to push the envelope way beyond what is considered kosher with most European beer drinkers, so if you like innovative, interesting styles of beer, America is the place to be right now.
I also have to disagree that none of it can be found in grocery stores or small liquor stores. In fact I do probably 80% of my beer shopping at grocery stores and small liquor stores, haha. I only go to bigger liquor stores (i.e. BevMo) when I'm in San Diego, which is less than 25% of the year. When I'm in San Diego, the big chain grocery stores tend to stock venerated names like Stone, Green Flash, Alesmith, Port Brewing, and Lost Abbey. Really top shelf stuff. When I'm away in Indiana, the chain grocery stores stock local favorites like 3 Floyds, Bell's, Founder's. So I'm willing to bet most grocery stores in most cities in America have at least something worth drinking
edited to add: in terms of qualification for my opinions, I homebrew beer and cider, and am a certified cicerone. I like to think that I know a decent amount about beer ;D Also, Lance's post has great advice and some top quality brands. Definitely give some of those a try sometime!
