Here we compare Kamut®, khorasan, and durum wheats for taste and performance differences in bread baking. The quick summary is that there seemed to be more terroir difference than species difference in the loaf appearance, and taste testers didn’t have consistent opinions about the flavors of all three breads. Some found durum more buttery, others found khorasan and Kamut more buttery. Same with sweetness.
