Mizzou Agroforestry teamed up with the University of Minnesota to conduct a black walnut taste test with 100 participants. Taste testers rated each sample for aroma, flavor, texture and overall liking. Black walnut has a stronger, more distinctive flavor than the more commonly available English walnut, which many consumers describe as milder. Even so, 40 participants preferred at least one black walnut sample over the English walnut. Three advanced breeding selections from Mizzou Agroforestry received the highest ratings because they had less bitterness and a milder aftertaste.
The study found clear differences among black walnut cultivars. Some performed nearly as well as English walnut, while others were rated much lower. These results will help breeders identify the flavor traits consumers prefer while continuing to improve yield, nut quality and orchard performance.
