I am certain there exist weird wines that could fool me (I’ve had a few really weird wines) but typical shit from the grocery store, I’m gonna be able to tell at least that much. I might even ID them more precisely than red or white. It’s not exactly subtle…
Then again I don’t have a clue how someone could fail to tell which is coke and which Pepsi in the “Pepsi challenge”. They’re wildly different flavors. I can tell by smell alone.
