With sales for Green Tea Kit Kat in 2015 up by 20 percent over the previous year, Nestlé Japan has decided to develop another Japan-exclusive flavor, this time based on the country’s well-known traditional brew, nihonshu, or sake as it’s known internationally.

The new Kit Kats contain sake powder that has been kneaded into the white chocolate-encased wafers, giving the chocolates all the flavor and aroma of a top-quality rice wine while providing a light and refreshing aftertaste. Available from February 1, the new variety comes in three-pack boxes for ¥150 at convenience stores, while the specially designed nine-piece box is available for ¥700 from souvenir stores around the country. The nine-piece packs feature a beautiful package in the shape of an isshobin, or 1.8-liter (61 fl oz) sake bottle.
