The light lilt of a flute fills a cramped second-story area in Tokyo that homes a burbling vat of fermenting sake.
The micro organism within the 670-liter tank will take greater than two weeks to show its contents of rice and water into Japan’s conventional alcoholic drink.
But they aren’t solely alive, they’re listening too, mentioned brewer Yoshimi Terasawa, and the kind of music coming from a loudspeaker under the tank determines how the spirit will style.
“The micro-organisms inside are activated by the vibrations, and the taste changes,” mentioned the 63-year-old chief brewer of Tokyo Port Brewing.
Music is among the many unconventional strategies Terasawa is utilizing on the solely sake manufacturing unit within the coronary heart of the capital.

Crammed right into a slender four-story constructing, the small-batch operation employs strategies that promise to assist the business resist the fallout of local weather change.
It makes use of modified equipment and ergonomic processes that eat much less vitality and labour than a conventional open-air brewery within the countryside.
“Making sake on this kind of smaller scale makes it easier to keep the production environment constant,” mentioned 45-year business veteran Terasawa.
The firm seems about 30 kiloliters of sake annually, or sufficient to fill nearly 42,000 720-ml bottles.
But altering client tastes and Japan’s getting old inhabitants have hit demand, and the federal government says the variety of sake breweries has shrunk two-thirds from its Seventies peak to only over 1,100 now, greater than half working within the purple.
Other challenges are a scarcity of labour as brewers retire, surging gas prices, and disruption in rice provide due to world warming.
Terasawa mentioned his compact brewery supplied a mannequin to satisfy these challenges.
The course of begins on a fourth-floor balcony, the place he and an worker steam the rice for 70 minutes.
Then they depend on gravity to funnel the rice by apertures in flooring and ceilings to a mold-application room on the third ground, earlier than fermentation on the second, utilizing faucet water, and at last bottling the sake at floor stage.
“In the future, small breweries like this will have a great deal of merit,” Terasawa added.
