This early season cultivar is one of the best blackberries for jam makers. Obsidian blackberry jam develops flavors like fresh cherry or Red Zinfandel for a complex and refined experience. We make this jam with whole fruit.

Obsidian Blackberry Jalm

  • The Obsidian blackberry is a combination of the marionberry, olallieberry, and the boysenberry, developed at OSU in Corvallis, OR. When these dark berries jalm up, they develop a flavor like red zinfandel. The balance of sweet and tart in the obsidian blackberry has earned them the nickname of “Jammer’s Delight”.
