Yes, but it's also good to be aware that there are limits to your perception and take advantage. The 80% rule definitely works here. I don't drink wine, but at least with beer, tequila, and coffee, there is a pretty obvious gap between the cheap/ low end stuff and the good stuff, but paying significantly more for higher end brands isn't worth it.
So focus on getting out of that low end category and really enjoy the good stuff because the supposed "great" high end stuff is rarely worth tripling what you pay (or more).
