Frogs Leap happens to be one of our favorite wineries. On the label on the back of the bottle with all the required warnings required by every governing body you can think of, the story goes that during the original labeling application the owners were so frustrated if them they put on their label "Open other end". Next time you see one of their bottles check out the label, and if you like a KILLER Zinfandel than buy it and find out for your self.
