Japanese whisky, specifically Suntory's Hibiki Harmony, is typically bottled at 86 proof, which is equivalent to 43% alcohol by volume (ABV). This is a standard proof for many whiskies, both Japanese and from other regions. The proof of a whisky refers to its alcohol content, with higher proof indicating a higher alcohol content.
Proof is calculated by doubling the ABV, so a whisky with 43% ABV would be 86 proof. The term “proof” originated from the practice of testing the alcohol content of spirits by soaking gunpowder in them and igniting it. If the gunpowder would still burn, the alcohol was considered “proof” of its strength. While this method is no longer used, the term “proof” has stuck around in the spirits industry.
Japanese whisky, like Scotch whisky, is known for its craftsmanship and attention to detail. The production process of Japanese whisky often mirrors that of Scotch whisky, with malted barley being used as the primary grain and aging in oak casks. However, Japanese distilleries have also incorporated their own unique techniques and flavor profiles, resulting in whiskies that have gained international recognition and acclaim.
In the case of Suntory's Hibiki Harmony, it is a blended whisky that combines different malt and grain whiskies from Suntory's distilleries. The harmony in the name refers to the careful blending of these different whiskies to create a balanced and complex flavor profile. The whisky is then aged in various types of casks, including American white oak, sherry casks, and Mizunara oak, which is a type of oak native to Japan.
The 86 proof of Hibiki Harmony is a common choice for whiskies as it strikes a balance between the flavors and the alcohol content. It allows the nuances of the whisky to shine through without being too overpowering. The aromas and flavors of Japanese whisky can be delicate and intricate, and a lower proof allows for a smoother and more enjoyable drinking experience.
Personal experience-wise, I have had the pleasure of tasting Japanese whiskies, including Hibiki Harmony, on multiple occasions. The 86 proof of Hibiki Harmony enhances the whisky's intricate flavors, allowing notes of citrus, honey, oak, and spice to come forward. The smoothness of the whisky is also notable, with a well-rounded mouthfeel and a satisfying finish.
Japanese whisky, including Suntory's Hibiki Harmony, is typically bottled at 86 proof or 43% ABV.

Whether enjoyed neat, on the rocks, or in a cocktail, Japanese whisky offers a unique and exquisite taste that continues to captivate whisky enthusiasts worldwide.
