Also, some of the most appreciated wines by wine connoisseurs are nigh-undrinkable to the uninitiated, and this tends to happen with most foods. Just sticking with wines, some greatly appreciate wines high in tannin, while I personally feel like I'm chewing cotton when drinking one of those wines: give me a decent vinnegar over those any day of the week.

You'll find similar acquired tastes in every food culture (stinky cheeses, fermented teas, ultra-hot peppers, acidic coffees, etc.).

The same actually happens with most art: most abstract art is completely meaningless to the vast majority of people - whether they're looking at a Pollock or generic art at Ikea, they wouldn't prefer either. Minimal music, such as Steve Reich's Four Organs, are profoundly distasteful to much of the population, while being adored by some in the music scene. Art films are routinely incomprehensible to general audiences, while winning critical acclaim.
