Usually you think of something like a dry cracker when you are trying to get a taste out of your mouth to retry a wine. I came across a couple of wine stewards who employ strange but effective palate-cleansing means:
Teriyaki Beef Jerky
Smoked Almonds With Jalapeno*
Weird. Very weird. But effective! I think that the smoky flavor of the jerky and the nuts will definitely slaughter any lingering taste in your mouth. It’s almost like shock-therapy for the palate. Everything from a white wine with searing acidity to a gloppy, tannic red beast will be tamed. Behold, the power of jerky! So the next time you are at a wine tasting event, don’t forget to put some jerky in your pocket.
*damn, how do I get the tilde over the n?
