Wine lovers, take note: There’s a new place to age wine, and it requires fins and a tank to get there.

Edivo Vina, a winery in Drače, Croatia, has added a twist to the art of winemaking, Its newest wine cellar is located beneath the waves of the Adriatic Sea.

The mastermind behind the underwater winery is Ivo Segovic, a 34-year-old vinter and diver. He says the seafloor offers the perfect conditions for aging wine.

“As I had been under the sea every day for years, I noticed that some 20 meters deep, the temperature is constantly the same throughout the year — 15 to 17 degrees Celsius — and that it is quiet and dark," Segovic tells The Associated Press. Traditional cellars are vulnerable to fluctuations in temperature.

Each bottle is aged above-ground for three months and then corked and placed into an amphora, which are strong enough to protect the bottles. The amphoras are sealed with two layers of rubber to prevent leakage and sunk about 65 feet deep for one to two years.

The winery opened to the public in April and offers guests the chance to dive with Edivo Vina staff to tour the wreck and the wine cellar, where they’ll find the amphoras secured in padlocked metal cages.

It took about seven years to perfect the process. The first attempt was a disaster: 200 bottles of wine were destroyed by the pressure of the sea. The bottles survived the second trial, but seawater leaked through the wax seals on the amphoras. A rubber coating now prevents against saltwater intrusion.

Wine experts say the undersea aging provides a stress-free environment for the bottles. Because of this, Segovic says, the wine has unique characteristics.

“We tried the wine and it had fantastic taste, color, and smell,” he says. “Much softer than the one from the cellar.”

A single bottle of Navis Mysterium — Sea Mystery — can be purchased online for about $60; or in the weathered amphora, it’s around $350.
