On the latest episode of "Adam Ruins Everything," host Adam Conover takes on so-called "wine experts."

In Zap2it's exclusive sneak peek, watch as some unwitting restaurant customers struggle to choose a wine, with actor John Michael Higgins standing in as the snooty wine connoisseur.

In the "wine pranks" segment, wine experts were fooled by testing two different wines that were actually the same wine -- the white wine was simply dyed red.

Next the experts were given the same wine -- one with a fancy label and one with a "table wine" label. The experts could not tell the difference.

"Wine is wonderful and of course wines taste different," says Conover. "It's just totally subjective, like all foods. We don't need sandwich experts because we know what we like. ... If you don't like it, it doesn't matter because there's no objective truth to what tastes best.

"We think of wine as a high-class item, only accessible by high-class people. But it's just tasty, fermented grapes. So forget the snobs, take risks and drink what tastes good to you."

"Adam Ruins Everything" airs Tuesdays at 10 p.m. ET/PT on truTV.
