Heineken may be the most international beer, available everywhere. I agree the North American product is not a favorite for me, but many of my stateside friends call it numero uno! It owns a number of well known Mexican and American brews, and many others around the world.
I believe some imbibers can somewhat identify different skunk/sweet/yeast/wheat flavors from one brand to another on the first pint.
One the second pint of a taste test, they are mostly guessing, possibly with 50 % accuracy.
Third pint: the only beer they can differentiate, one from another, would be a Guinness.
