Ahh, now THIS is helpfull. I stay out of the "What beer?"threads because everyone tosses out their favorite beer from their corner of the world, and it never seemed helpful. If you only have a few available, well then heck, it’s much easier to rank them. Here is how I would group them (note that this is grouping is made with beer snob hat off):
Becks
Lowenbrau
Heineken
Grolsch
Pilsner Urquell
All these are quite similar to the untrained taster, and in my opinion, nothing special. (Note that putting Urquell in here will put me on the Beer Mafia hit list) They are the same style as American beers, just better - more taste, body, etc. But if you don’t like Bud, then my experience tells me that you won’t like these much either, at least not at first.
Hefeweizen Wheat Beer
You’ll either like it or hate it. I hate wheat beers.
Red Stripe
Quite similar to American beers, just a little “more” but blander than the European group.
Bass
If you liked the Black and Tan, you should like Bass.
Guiness
As mentioned, buy only the kind with the widgets (the can or the plastic looking bottle) Some who like B&T do not like straight Guiness. But as long as you have the Bass, you can make your own B&T, which is much more fun than buying a pseudo B&T already in a bottle.
Modelo Negro
Different than the rest listed, dark but not bitter. I like this in Mexican Restaurants, but usually get Bohemia to go better with the food (Bohemia also a lager that is similar to American beer, but just “more” But more in a way I like better than Heineken).
Samuel Adams Summer Ale-No opinion.
And a picky correction from upthread- A real snob Black and Tan is made with Harp, not Bass. But Bass is perfectly tasty for it.
I pity those of you with limited beer selection. I don’t know what I’d do without a local supply of lambics to keep my wife happy!
