Creamer gone bad.
When these flavors came out a few years ago, they tasted fine. I recently tried White Chocolate Mocha and it's absolutely horrible. It has a very chemical taste. I've never tasted anything like it. The Caramel Macchiato is almost as bad as the other flavors. They changed the recipe for the worse. If you want to try one that's done right, try Lucerne's white chocolate mocha.
