I've seen some pretty strange drink combinations. Mixology can sometimes go from genius to insane in a nano-second.
But people have decided that the liquid marriage of cola and red wine is a good idea.
It's apparently a thing. They call it kalimotxo.
Kalimotxo (pronounced cal-ee-MO-cho) is literally equal parts cola and red wine. The cheaper the better (the wine that is, although at this point I'm not sure it matters when it comes to soda).
I've had some bad wine in my lifetime, but I've never thought to myself, "You know what would make this taste better....Pepsi!"
It's also supposedly a Basque-country classic.
Good for them...as far as I'm concerned it can stay there.
