Raspberries are the edible fruit of a plant species in the rose family. There are many types of raspberries — including black, purple and golden — but the red raspberry, or Rubus idaeus, is the most common. Red raspberries are native to Europe and northern Asia and cultivated in temperate areas worldwide. These sweet, tart berries have a short shelf life and are harvested only during the summer and fall months. Another advantage of IQF Fruit is that raspberries are available all year round when frozen.
