Or so I thought. It turns out that even going to weekly tastings you don't stumble into the funky stuff. You'd never stumble into dessert wines or wines made with wild yeast. You'd rarely stumble across their barrel-aged whites. They knew what sold, and they'd highlight that.
I still order a case (12 bottles) or so a year from my favorite winery in southern Germany, where I met the vintner in said department store. I've even stumbled across one of their bottles from the sommelier in my favorite restaurant in Berlin. But it's truly only from high end restaurants (and their drink pairings) that I've discovered how wide the palette for wine goes. Not to put too fine a point on it, but I've been to Noma, mentioned in the lead to the original article, and their wine selection, like with most top end restaurants, is genuinely palette-stretching.
The last is obviously a privileged thing that not many can do, but if you are traveling, absolutely ask the locals what regional wines you should try, and what years. The weirdest & best wines I've had so far were in Delaware, Central California, Spain, Israel, South Africa, and Central France.
For example, I did a tour of some of the dozen wineries in Delaware (who knew?) and tried a varietal I hadn't heard of before: Norton. It's basically the only native American grape which is practically suited for winemaking, and has been in use since the 1700s. It was once so popular that a Missouri wine using it won "Best Red [Wine] of All Nations" in a competition in Vienna in 1873. The one I had was really weird tasting, and I highly recommend it.
