As you can infer from this very tastefully-done video, The King wanted the perfect red wine to pair with its world-famous flame broiled Whopper (black, or otherwise)...so they charred some barrels, swizzled some chicken fries around (probably) and called it casked perfection.
With fluid ingenuity like this, you can expect Burger King to reign in Spain for another 40 years, at least.
