The fabrication process of Kujira Ryukyu Whisky is meticulously crafted, honorably reflecting the skills passed down through generations at the Masahiro Distillery. It begins with the selection of the finest Indica rice, a staple in Okinawa, known for its exceptional quality and flavor potential. The cultivation of these rice grains is carefully managed to ensure optimal conditions for fermentation. After harvest, the rice is carefully milled to the desired texture before being subjected to a unique mashing process utilizing black Koji, which plays a pivotal role in converting starches into fermentable sugars. This specific mold, distinct to Okinawa, enhances the rice's natural flavors, yielding a fermentation that rivals traditional methods in richness. The mash is then fermented in temperature-controlled conditions to promote even fermentation, crucial for developing the complex profiles inherent in the whisky.
Following fermentation, the liquid is distilled in pot stills, ensuring that the delicate flavors are preserved during this key stage of production. The resulting distillate is then placed in new White Oak Virgin Casks for maturation, where it is aged for a minimum of 10 years. The aging process is carefully monitored, as the subtropical climate of Okinawa influences the whisky's development significantly, allowing it to mature with unique characteristics that distinguish it from whiskies produced in more temperate regions. Throughout the aging period, the whisky interacts with the wood, extracting various essential oils and flavors that contribute to its final profile. After reaching the desired maturity, the whisky is carefully blended to achieve consistency and balance before bottling, resulting in an expression that is both artisanal and genuinely representative of Okinawan heritage.
