semi-expert here....they all taste somewhat different, after you've been drinking beer for a few years. I like to drink the same beer all the time. Bud is king where I live, but I cannot stand it. Gives me headaches all the time. Michelob (same company) on the other hand, is heaven to me. Problem is only half the bars I frequent have it. So I settled on Bud Lite, available everywhere..not too bad
Used to go for Schlitz, Falstaff, a few others. One thing I really avoid is the stuff on tap. The quality there is really inconsistant...never know what you'll get. I always drink bottled beer, no cans, no tap stuff. Taste is better and it's usually colder.
