The Japanese whisky highball is a two-ingredient cocktail. It’s just like any other highball but uses Japanese whisky or is made in Japan. So what’s the big deal you may wonder?
Well the highball was a drink that helped popularize whisky in Japan. It’s always held a special regard. The bartenders in Japan have taken the simply drink and applied more craft to it than typically found in the West.
Fine-tuned temperature and dilution are key variables. The choice in whisky and water is also important.
