> "If I like a glass, did I really like it, or did I just like the experience? Or did I feel pressured to like it? Or did the high price tag convince me I should have liked it and if I didn't I just don't have a refined enough palate? Should I stick with it to see if I acquire a taste and understand what all the fuss is about?"

You're not asking "Did I really like it". You already answered that, there is no 'true' liking. You're asking "Would I have liked another one better, all other things being equal?"
