Aside from futbol, clubbing, and delicious paella -- Spain's unique cultual skils include creating wine-based beverages that bewilder and confuse the masses. Consider Kalimotxo: equal parts red wine and Coca-Cola. I can tell you from first hand experience, it's surprisingly delicious.
Now, put this in your chalice and drink it -- Burger King's Whopper Wine. Available exclusively in Spain, designed to celebrate 40 years of BK in Iberian peninsula. Yes. This is seriously a thing that actually exists on this planet.
