Lento: The Kokuto Shochu That Gets Played Classical Music

The name is a musical instruction. Lento is Italian for slow.

That's not decoration. This shochu is matured with classical music played into it, and the tempo marking is the point.

What Acoustic Aging Actually Is

Amami Oshima Kaiun Shuzo matures Lento for around three months in tanks fitted with transducers, devices that convert an audio signal into physical vibration.

Mozart, Beethoven and Vivaldi get played into the tanks. The sound becomes vibration, the vibration agitates the liquid at different frequencies, and the shochu moves against the wood more than it would sitting still.

Whether you find that charming or absurd, the mechanism is ordinary: agitation increases contact between spirit and wood, and more contact extracts more. Distilleries elsewhere rock barrels or roll them for the same reason. This one uses Beethoven.

Where It's From

Amami Oshima, in the islands between Kyushu and Okinawa.

Kokuto shochu, made with brown sugar, can only legally be produced in the Amami Islands, which makes it one of the most geographically restricted spirits in Japan. Kaiun Shuzo brews with underground water from Mt. Yuwan, which was registered as a UNESCO World Natural Heritage site in 2021.

The base spirit is vacuum distilled, which keeps it light before the aging does its work.

What It Tastes Like

Soft and gentle, which is what the name promises.

Brown sugar shochu is never as sweet as people expect, the sugar ferments out, but it leaves behind a rounded, faintly molasses-like character. The aging adds vanilla and a little spice on top of that.

Lento became the best-selling shochu in Japan and is what most people mean when they say Amami kokuto shochu.

How to Drink It

On the rocks or mizuwari. It's soft enough that heavy dilution flatters rather than damages it.

Oyuwari, with hot water, brings out the molasses side and is very good in cold weather.

Pair It With

Kokuto shochu is versatile in a way imo shochu isn't. It goes with fried food, grilled skewers, and richer plates like pork kakuni equally well.

It's also one of the better things to drink with dessert, try it near dorayaki.

Try It at Juraku

Lento is on the shochu list at Izakaya Juraku, Lower East Side, alongside our other Amami kokuto bottles.
