Raisin varieties depend on the type of grape used, and are made in a variety of sizes and colors including green, black, blue, purple and yellow. Seedless varieties include the sultana (also known as Thompson Seedless in the USA) and Flame grapes. Raisins are traditionally sun-dried, but may also be water-dipped and artificially dehydrated.
"Golden raisins" are treated with sulfur dioxide after drying to give them their golden color.
