The dictionary definition of "snob" is: "one who thinks that money and rank are very important, and has contempt for those he considers inferior." (Webster's New World)

I know many people who are sophisticated and erudite on certain subjects but who show no hint of snobbery. They are happy to share their knowledge with all who ask but understand that others have different priorities that leave them uninterested in a particular issue, be it wine, food, cars, audio or whatever.

So, yes, it is possible to appreciate some objects more than others, but that doesn't mandate that others who don't share that appreciation are inferior.
