My son recently came home from a little holiday in Japan and bought his mum home something she knew she would like. It’s Kit Kat infused with sake!

The latest collaboration between the famed chocolate snacks and the Japanese spirit is almost four centuries in the making and uses one of the highest classes of sake.

Over the years, Kit Kats’ position in the Japanese snack pantheon has continually evolved.

First, they were just those foreign chocolates, right? Then they became a treasured good luck charm for students taking entrance exams, and after that, they acquired their status as champions of limited-edition regional flavours, taking your taste buds on a tour of Japan.

Then Nestlé hit upon the genius idea of sake-flavored Kit Kats. At first, it seemed like it might have been a case of the company taking its Japanese theming a step too far, but it turned out to be delicious, and now the company is collaborating with one of Japan’s most respected sake brewers, which was founded in 1625.

When Hyogo Prefecture’s Sakura Masamune first started making sake, Japan was still ruled by a shogun, and Western food of any kind, let alone chocolate, was virtually unknown in the country. But under the guidance of 11th-generation master brewer Tazaemon Yamamura, Sakura Masamune has teamed up with Nestlé to jointly develop the new Kit Kat Mini Nihonshu Sakura Masamune Diginjo flavor.
