Wine growers in western Japan's Tottori Prefecture have found an unusual storage place in a tunnel inside a dam. It offers ideal aging conditions for bottled wine through the year.
The inspection tunnel inside Togo dam in Yurihama Town is shielded from sunlight and has a stable temperature of around 10 degrees Celsius.
The cool and dark environment helps maintain the quality of red wine. Local growers plan to store bottles under the dam for up to five years.
Wine grower Sugimoto Satoru said: "This place is a very good environment for aging wine. This storage place gives me plenty of ideas for making interesting wine."
When ready for sale, the bottles will be labeled to show they were aged in the dam.
