Storage & Aging

CEPタブ

How to store opened and unopened bottles, and what aging does to sake, shochu and umeshu.

Perspectives

From the Cellars of Tatsugo to Brown Spirits

Nestled in Ogachi, Tatsugo Town, within Kagoshima Prefecture’s Oshima District, Machida Shuzo rests between deep subtropical greenery and the coral reef seas. Kokuto shochu, crafted from brown sugar, holds a geographical indication that restricts its production strictly to the Amami Islands. Within this protected heritage, Machida Shuzo presents Honkaku Shochu “Sato no Akebono Gold” as an alternative philosophy for enjoying kokuto shochu. At 43% ABV in a 720 ml bottle, it pours into the glass with a faint amber hue that elegantly catches the light. At first glance, it could almost be mistaken for whisky. Yet, its true identity remains a honkaku shochu, born from Amami brown sugar and rice koji, then patiently matured in oak casks.

A Sake-Brewing Craft That Turns Amber in a Snow Cellar

At the foot of sacred Mount Hakkai in Minamiuonuma, Niigata Prefecture, there is a semi-underground storage cellar packed with roughly 1,000 tons of natural snow. This is Hakkaisan Brewery’s yukimuro, or snow cellar. Without any artificial electric cooling, American white oak barrels rest silently in darkness, free from vibration, at a year-round temperature below 4°C. What lies inside them is neither whiskey nor bourbon. It is authentic rice shochu, created by a sake brewery using the techniques and byproducts of sake making. Its name is Hakkaisan Authentic Rice Shochu Oak Barrel-Aged “Fubaika.” Bottled at 40% ABV, this limited production has been quietly crafted since its debut in 2016.
