I know what it is like to have no context for a certain flavour, to just not "get" it, and maybe even intensely dislike it. I've wanted to like root beer and all the variants since I came to the USA fifteen years ago, but I simply don't like it. We didn't have root beer in Ireland growing up (though I vaguely remember it being in McDonald's on Grafton Street in the mid-70s, soon to disappear from the menus. However perhaps my memory is playing tricks on me, because McDonald's doesn't carry root beer in the US, at least none of the ones I've been in, largely on the East Coast). I've wanted to like it too, and I'll regularly try it if a friend has some, and I keep thinking perhaps one of the "fancier" brands - e.g. Boylan's - may do the trick. But it never works - it always just tastes like sweet muscle rub to me.
