Black Raspberry

Black raspberry is a small fruit (botanically an aggregate fruit) that weighs between one and two grams. Almost all commercial production of black raspberries is from developed cultivars of Rubus occidentalis. Oregon accounts for over 90% of black raspberry production in the United States.

Black raspberry plants yield significantly less fruit than their red counterparts and also commonly suffer from a raspberry mosaic disease complex that gives them shorter lifespans than other cane berry plants. Because of this, they can be costly to produce on a large scale.


Because black raspberries can be harvested only for around three weeks during the year, usually starting at the beginning of July, their fresh market presence is limited. Mostly, black raspberries are made into jams, individually quick frozen, freeze-dried, or otherwise processed. Black raspberries contain less sugar and more fiber than most other berries. They can also be found as an ingredient in ice creams and soft drinks due to their unique name and the flavor of the berry.

Cancer research

Black raspberries have been investigated in relation to the treatment and/or prevention of colon cancer, esophageal cancer, and skin cancer.
