Now this gets tricky so let’s for a moment consider what the word snob actually means. Allow me to use a definition for the free dictionary online: a person who believes himself or herself to have superior tastes and is condescending toward those with different tastes.
Nowhere is it stated that one must prefer the expensive over the inexpensive to be a snob. Fundamentally snobbism is driven by a heightened sense of self importance and condescension towards others. Thus we do have snobs who favor the expensive or exclusive over the ordinary but we also have snobs who favor the geeky, organic, or even inexpensive over the wines other people like and enjoy.
Get over yourself. If you don’t like a type of wine, that is fantastic. Now shut up and drink what you like and leave me, and everybody else in peace to enjoy what we like. Snobs also tend to stay tightly within their comfort zones, lest they be revealed as something less than the expert they imagine themselves to be, so fortunately they are all too often boring drinking partners who are not terribly missed!
