It might seem like the term front plate refers to the front of the mouth. But front palate, mid palate and back palate are temporal terms—that is, they indicate time. So the “front palate” is comprised of the flavors, aromas and textures you experience in the first few seconds after you put the wine in your mouth. Mid palate is what you experience a few seconds after that. And back palate are the sensations, flavors and aromas at the end of the experience, right before you swallow or spit.
