Iwai whisky is a Japanese homage to great American-style spirits, and based on the Iwai sell sheet, it is made of mash bill, mostly corn, followed by malt and a hint of rye.

After distillation, it is aged in used bourbon barrels for a certain time to develop taste and color. 

The Iwai whisky contains 40% alcohol content (80 proof), and it makes a great classic cocktail because it does not fade easily when mixed with different flavors.

Aging Process & Age Statement

While not all producers are associated with the said group, the labeling requirements aim to increase quality and transparency among members and consumers.

In addition, Iwai whisky is aged in used bourbon barrels sourced from the United States.
