Crimson Raisins: Crimson Beauty!
When you dry seedless Crimson grapes and treat them with sulfur dioxide, you get Crimson raisins. These raisins were first developed in Fresno, California, and released in 1989. Crimson raisins are cylindrical to oval, have a medium thickness, and firm, crisp skin. Crimson raisins have a delicious, sweet flavor.
