It's McDonald's! It's Coca-Cola! If they sold it in Starbucks, it would be every imperialist's dream beverage!
Except not.
It is very hard to describe this taste, except to say that it is not good. After taking my obligatory swig, I poured the rest of it down the sink. Justin thinks it smells like tuna and tastes like barbecue sauce. I can be a bit more specific.
In Korea, they have a barley tea (pictured at left). If you mixed it with Pepsi/Coke, that's what McCol would taste like.
In fact, that's probably what it is. "Maek," in Korean, means barley - "Maek-ju," or "barley alcohol," is the Korean word for "beer." So "McCol" is actually "Maek-Col," or "Barley Cola." Hence, in retrospect, the picture of the stalk of barley on the can.
Mediocre Korean skills FTW!
