Hibiki 35-Year-Old Yoasai and Hekiyo Bottles: Why Cloisonné Enamel Craftsmanship is the Most Difficult in the Hibiki Series
The "Yoasai Bottle" is a metal-based cloisonné enamel bottle specially developed by Suntory for the Hibiki 35-year-old. "Hekiyo" refers to the jade green enamel glaze, inspired by the clear blue sky. Cloisonné enamel (七寶燒, shippoyaki) is a traditional Japanese metal-based enamel technique: metal wires are first bent into patterns, then filled with enamel glaze, and repeatedly fired and polished. The process is complex and yields a low success rate. For this reason, these limited-edition Yoasai bottles are considered one of the most challenging artisanal bottles in the Hibiki series. Paired with the high-aged blended whisky of Hibiki 35-year-old, both the liquid and the vessel stand at the pinnacle of the series, which is the fundamental reason for its long-term scarcity in the secondary market.
About Hibiki and Suntory
Hibiki is Suntory's flagship blended whisky, not a single malt. One of the rare aspects of its blending craftsmanship is the use of malt whiskies aged in plum wine casks, which imparts a smooth, fruity sweetness to the body, a flavor profile difficult for other blended brands to replicate. The overall body is composed of malt whiskies from Yamazaki and Hakushu, and grain whiskies from Chita. For the 35-year-old, the old stock of unblended whiskies available for blending is already scarce. Furthermore, high-aged whiskies evaporate at a rate of approximately 2% to 4% annually in the cask due to the "Angel's Share," resulting in significant cumulative loss and naturally limiting the number of bottles produced. This page focuses on explaining the identification methods for cloisonné enamel craftsmanship and the market positioning of the Yoasai bottle.
