I made a loaf of bread today using KA white wheat flour- used straight whole wheat. If I use whole wheat flour I usually add no more than a cup of it to 2 cups or more of unbleached AP or bread flour. The bread looked good even though I could tell it was going to be a little heavy but the taste was awful- had a bitter taste. Is this normal for WW flour? I keep all my flours in a cool place so I don't think it was rancid but yuck! Any suggestions? I won't usually turn my nose up at any bread but this one is going in the trash.
