Yooper Sisters Artisan Jam was started in 2015 by two sisters exploring their passion for Michigan wild and locally grown fruits. Natives to Michigan, their summers were spent picking locally grown fruit and camping trips to the Upper Peninsula to pick wild blueberries. These days, those hand picked wild blueberries are the star of many flavors of Yooper Sisters jam.  Each jar is 7.7 oz. Try one today and relish the taste of the U. P.!
