Johnnie Walker Double Black is a smokier, more powerful version of the iconic Black Label that has historically only been for sale in Europe and duty free shops. So when Johnnie Walker made it available for a limited time in the US, we wanted to make sure the impact was as powerful as the flavor of the blend. "The Double Countdown" teased the secret launch with a countdown that made Walker fans guess the news. Once the whisky hit the shelves, the countdown started again. But this time, the clock counted down to when Double Black would be gone from stores.
