It's what people usually say to others who don't or can't convince themselves to like something which is shit because its expensive. I had a friend who was like that with caviar and insisted that my taste wasn't "refined" because I wasn't willing to convince myself that the $200 dollar made it not taste and smell like cat food (which it absolutely still did), I enjoy fish but I do not like caviar, it smells and tastes like cat food smells like. Even if it's $2000 I'm not going to enjoy it, I'm just going to be bummed I wasted money better spent on something much more enjoyable in higher quantity.

That’s what having a “developed taste” means. Yeah it’s all opinions, but you can’t even know what your opinion is of something unless you try it, and you can’t develop an in-depth opinion of something unless you’ve tried a whole bunch of similar somethings.

I understand that and agree, but please also understand that when someone dismisses your opinion of something like mine with caviar by saying your pallet is unrefined, they're not saying you haven't experienced enough, they're chastising you for not pretending to like it the way they do. Which is what my comment addresses, because they're not telling you you need to experience new things to get a better understanding, they're saying that their opinion is the correct one objectively and not just their opinion.
