The Home of the Whopper is about to become coffee central.

Burger King has announced a massive upgrade of its coffee platform -- doubling the number of coffee beverages it sells to 10.

The chain spent nearly a year developing the new line with Seattle's Best, which is owned by Starbucks.

So every time a consumer purchases a cup of coffee at Burger King, Starbucks makes a profit.

Beginning this week, BK is replacing its current brewed coffee with a smoother Seattle's Best blend.

It also will have a new decaf and a new hot chocolate.

The latte rollout begins in March.
