Ha! Very true and well said.
For many decades I made wine professionally. It's very much the same in the wine biz. Every wine is at least somewhat different, but there is no objective or absolute standard of wine quality. (Defect, yes.) Since wine quality is almost entirely subjective, people, even professionals, often judge a wine's "quality" based on price.
Some inexpensive wines are very good, even some Two (now Three) Buck Chuck. (Now THERE'S a story!) It's largely a matter of selling one's story to the customers and embellishing it with a fancy or unique label or bottle, then convincing them that the wine's difference somehow makes it special and uniquely desireable. Then, if the quantity is limited — this one barrel or this special vineyard — a talented vintner (vintner means "wine merchant," NOT winemaker...) can con an outrageous price out of a bamboozled consumer.Caveat emptor!
