Fast food giant giving away wine...really!

Nothing says "Happy Anniversary!" like a fine wine, according to one fast food giant.

To celebrate four decades in Spain, Burger King's Spanish unit is trading burgers for bottles.

Customers who share their Burger King experience will have a chance at winning one of 40 bottles of Whopper Wine aged in barrels of wood that has been flame-grilled in a Burger King broiler.

To enter, people can either upload a photo, write a story or submit a YouTube video about a memorable moment at the chain.

This isn't the first time Burger King has strayed from its burger and fries roots. Earlier this year, its Japanese unit came out with a Whopper fragrance.
