I consider myself to be rather high-brow since I enjoy tasting expensive wines.
I like tasting wine too, but it doesn't have to be expensive. I just think the sensory examination of any wine is cool.  
I agree, but wasting money on expensive ones makes me feel better about myself.
Well, maybe you should start referring to yourself as a sommelier! They are professional wine tasters. 
Perhaps I should. I usually avoid labelling myself but in this case it might be appropriate! 
Sommeliers usually work in fine restaurants and specialize in all aspects of wine and how wines match with foods.
