The production methods of all varieties of raisins and currants are practically the same. Drying is achieved either by direct sun exposure in the vineyards or by tunnel drying. The choice of production method mostly depends on the country of origin. Varieties depend mainly on the type of grape used. Sultana grapes, also known as Thompson Seedless, are used for the production of sultanas, whereas flame raisins are dried flame grapes. Currants are dried Black Corinth grapes, a seedless variety also known as Zante. Currants can be easily spotted as they generally are smaller than raisins and have a more intense

flavour. The colour of the grape changes in the drying process, Thompson grapes going from green to dark brown, flames from dark red to black, and currants from dark blue to black. Golden raisins are produced by applying sulphur dioxide to Thompson or Sultana grapes before drying, preserving their light colour. Raisins are very well known product, widely used as an ingredient in the bakery industry. Other applications range from the use for production of confections to an ingredient in sauces and condiments or consumption as a snack.
