There's also a thing that wasn't said. In a lot of countries, people preference go to vine wine, varietal wine, or vin de cépage in french. More easy for people to say " I prefer Chardonnay than Sauvignon, or I don't like cabernet sauvignon, it's too tannic". I think it's best way to learn about wines, varieties, and take easy pleasure for barbecue, or parties where we can drink a bit (and don't care about taste, that is not the deal of party). There's no surprise, you like cabernet sauvignon, you buy it , you drink it, it's tasty as you already know, etc.
But as far as I'm concerned, if I want to take real "plaisir", I go on "terroir" wines, which can bring some other tiny varieties, different from heavy production ones (cabernet sauvignon, merlot, syrah, gamay, grenache, pinot noir etc.) for example, mourvedre, cesar (for red whine), which can't do good cépage wine but bring so many tasty notes in mix wines more that you can have with cépage wine. The fact is to discover, sometimes it's just horrible, but sometimes it makes you a quasi gustative orgasm, when a good wine is associated with good cheese, good meat or chocolate for example.
I can't stand drinking wine as eating Mcdo food. If I go to a region, I don't want to taste a wine similar to what I already know. I can't stand tourists who come in french wine region or anywhere else to drink wine, and want to drink only cabernet sauvignon because they like it, but don't want to discover local wines. For me it's the height of laziness and narrow-mindedness. I know it's quite fulsome, but wine is a serious thing, not for children!
