Kit Kat Japan has developed more flavors than anywhere in the world, the latest of which comes from aged whisky barrels in Scotland.
The new flavor, aptly called Whisky Barrel Aged, is created from cacao nibs that were kept for 180 days in barrels once used for aging whisky.
The barrels are located in Islay, an island off the west coast of Scotland home to the peated Scotch whisky, according to Forbes.
They are rotated weekly to ensure that the cocoa touches them, which helps develop a better aroma and taste.
The cocoa reportedly comes from Ghana and is described to have a mild taste, making them ideal for blending with other flavors.
The finished product is a rich, bitter-tasting chocolate wafer suitable for “adults who can enjoy the delicate aroma and taste of whisky,” according to SoraNews24.
Nestlé Japan, which oversees the local Kit Kat, says this is the first Japanese Kit Kat produced overseas, with its country of origin labeled in the U.K.
Kit Kat lovers can get the new flavor for 300 yen ($2.88), but it’s worth noting that the product is only sold in winter (beginning Dec. 15), since it uses rare cacao nibs.
The new flavor will go on sale on seven Kit Kat Chocolatory boutiques across Japan, headed by pastry chef Yasumasa Takagi.
