What is IWAI Tradition?

Speaking of the birth of the first whisky distillery in Japan, you probably know that Suntory’s Yamazaki Distillery was started by Masataka Taketsuru with Shinjiro Torii. It was Settsu Shuzo (President Kihe Abe and Managing Director Kiichiro Iwai) who sent Masataka Taketsuru to Scotland to study whisky production in 1918.
After returning to Japan, Masataka Taketsuru, who had learned about whisky making, submitted the Taketsuru Note (whisky training report) to his boss, Kiichiro Iwai, which became the starting point for domestic whisky. At Settsu Shuzo, whisky production was halted due to financial difficulties caused by the postwar depression, and Masataka Taketsuru left the company. He then joined Kotobuki-ya (now Suntory). Suntory established Japan’s first whisky distillery, the Yamazaki Distillery.

Meanwhile, Kiichiro Iwai became an advisor to Honbo Shuzo in 1945 and obtained a whisky manufacturing license in Kagoshima in 1949. Honbo Shuzo’s Mars Whisky was born.
Mars Whisky launched a product named “IWAI TRADITION” as a sign of respect and gratitude to its creator, Kiichiro Iwai.


Blended whisky with additional maturation in sherry casks

IWAI Tradition Sherry Cask Finish is a blended whisky made by adding additional maturation (finishing) to the Iwai Tradition described above in the empty casks used for the ultra-sweet Pedro Ximenez sherry. In addition to the rich flavor of IWAI Tradition, this whisky has a well-balanced aroma of brown sugar, maple syrup, and elegant sweetness derived from sherry casks.

Sherry casks are famous in Scotch, such as Macallan and Glendronach, and are also used in Japan by the Yamazaki distillery, but not many sherry casks are used in Pedro Ximenez, which is the sweetest sherry. It will be very interesting to see how the sherry cask finish turns out this time.
