Underwater Aging at Castel dell'Ovo in Naples: A Unique Experiment for 450 Bottles of Limoncello- Antica Distilleria Petrone

On Wednesday, September 25th, in the quaint waters of Santa Lucia's small port in Naples, an extraordinary event took place. A case containing 450 bottles of limoncello from the renowned Antica Distilleria Petrone was submerged, marking a significant milestone for the Caserta-based company. Notably, this is the first time the aging process is being conducted in the Gulf of Naples, following the previous underwater aging experiments off the coast of Mondragone, near the ancient submerged city of Sinuessa.

For this prestigious experiment, Andrea Petrone, the general manager of Antica Distilleria Petrone, chose the iconic backdrop of Castel dell'Ovo. The limoncello, a quintessential Italian liqueur and a symbol of Campania, will rest 15 meters below the surface for approximately a year. During this period, it will be gently rocked by the sea currents, maintaining a constant temperature, and remaining completely shielded from light, oxygen, and lunar phases.

Upon retrieval, the limoncello will undergo a rigorous research program conducted by the Department of Agriculture at the University of Naples Federico II. These studies aim to scientifically evaluate the effects of underwater aging on the maturation of the distillate. Andrea Petrone expressed optimism about the potential outcomes, noting that previous studies on Elixir Falernum showed that underwater aging enhanced the liqueur's density and aromatic profile. He anticipates similar improvements in the limoncello after its year-long submersion.

This initiative also carries a significant social component. The ArcheoClub of Italy and the young participants from the Area Penale di Napoli, who are involved in the MareNostrum and Bust Busters projects, were integral to the event. Rosario Santonastasio, the national president of ArcheoClub d'Italia, highlighted the dual nature of the experiment, blending scientific research with social engagement. The young participants, who have undergone scuba diving and theoretical courses on geological, environmental, and historical heritage, contributed to a memorable day, forging new paths in their personal development.

This remarkable event was made possible through the collaborative efforts of the Municipality of Naples, the Navy, the Coast Guard, ArcheoClub d'Italia, the Royal Yacht Club Canottieri Savoia Napoli, and YDigital Firm.
