Pine Nut Bitter Taste
For reasons that are not understood, some people experience a persistent bitter-metallic taste after eating pine nuts (aka: pignoli if you live in Italy). This taste can last a few days or up to two weeks. Nothing tastes good because the bitter taste permeates the mouth. It isn't a "disease", nor does it cause any illness...just an annoying taste.
There isn't much a consumer can do to prevent Pine Mouth. All pine nuts look alike and there are no tell-tell signs. The good news is that the condition is self limited and normal taste finally resumes.
Have any of you readers had Pine Mouth?
