The difference between wine tasting as opposed to wine drinking is that the former involves concentration, contemplation and consideration. Both are enjoyable; however they serve two completely different objectives, and are not necessarily mutually exclusive. Wine consists of a complex myriad of substances and the composition can be broken down into four major parts, as perceived by the senses. Wine tasting is a skill and is intended to be fun! Go on try it!

'Gone, inner and outer,  no moon, no ground, no sky. Don't hand me another glass of wine.Pour it in my mouth.
I've lost the way to my mouth.' 
Rumi
