Rainbow whisky is a product of a Ji-whisky maker named Aioi Unibio located in Nishio City. Ji means local in the Japanese and it’s an equivalent to American artisan whisky.
The company was formed in October 2004 by merger of three local companies and mainly produces mirin (Japanese equivalent of sherry), sake and shōchu. Rainbow is a locally popular standard Japanese blend. The label states that whisky is made of “malt and spirits” suggesting that the latter might be neutral alcohol and not the grain whisky. Rainbow is bottled at 37% abv; the Japanese tax regime charges extra for every percentage point of alcohol by which that number is exceeded.
