I knew a super-taster. She was a foodie and a chef. Her favourite things were Oreos and vanilla ice-cream. She could tell if the milk was left out of the fridge for a minute. She could distinguish all the variance in wines but didn't specifically enjoy any of them. I think a lot of the pleasure in wine tasting is the 1-upmanship. Personally I have been recommended wines for certain meals that complemented so well it made me notice. That's good but only in context not in isolation.
