Kit Kat is known for special editions which are marketed under its own chocolate label. In Japan, the brand has a dedicated chocolatory in Shibuya for the making custom versions. Their new chocolate features cacao nibs aged for six months in the wooden whiskey barrels from Scotland s famous Island of Islay, home to the world’s cult-like Scotch whiskey. They are rotated once a week to equally distribute the taste and aroma of the whiskey through the cacao nibs. Since they are rare and only available for the winter months, this luxurious chocolate edition will only be available in the winter.
