Made with black raspberries from Oregons Willamette Valley, this is our signature and most beloved flavor. The basic ingredients may be the same, but there are some Graeters flavors no one else has been able to duplicate. Graeters Black Raspberry Chocolate Chip Ice Cream for example, was Dick Graeters creation. The flavor was a childhood memory for him. I remember as a youngster buying black raspberry ice cream from a local drugstore. Black Raspberry Chocolate Chip quickly became and remains our bestselling handcrafted ice cream flavor.
