This is how I know it's not fake: I was fortunate enough to taste very expensive wines repeatedly as a teenager, not understanding their significance. Yeah I thought the whole thing was snobby, but the wine just tasted so good! When I bought mid-tier wine for the first time at age 21, it tasted "hot," like rubbing alcohol. Same with all the others from the grocery store. I still buy it but often leave it sitting for hours before drinking it, even though I haven't tasted any expensive wines in several years. My friends always say I have low standards for living conditions, which maybe I do, but when it comes to wine, seems like I'm permanently spoiled.
