The sea keeps a record. We are learning to read it.
How OCEAN CELLAR™, which predicts the sea's time,
works 30 m below the sea off Namhae.
We record what the sea writes.
Every day, we measure and record the sea 30 m down off Namhae, where the bottles rest.
Water temperature and salinity, currents and waves. We write down what the sea writes, without missing a day.
The water here moves differently with each season. For as long as a bottle stays in the sea, our measuring never stops.
We predict the path time will take.
From 112,316 tasting records, we learned how Champagne changes as it ages.
The six axes rise and fall together, and the balance settles anew.
We do not promise a better path. We only draw a different one from land.
On retrieval day, we are put to the test.
We predict how the sea will age each bottle, and seal that prediction before retrieval.
On retrieval day, we set each bottle beside its twin kept on land and taste them side by side.
We do not say whether we were right. The sea is the judge. The results are published as they are.
Next retrieval · December 2026
What is verified recalibrates the model.
Each gap rewrites the next prediction. With every retrieval, prediction and reality draw closer.
Hold your phone to the bottle, and its sea opens.
Its coordinates, depth and water temperature, and the time it lived at sea. No two records are alike.
We record what the sea writes.
Every day we measure and record the water where the bottles rest, 30 m down off Namhae. Temperature, salinity, currents, waves. We take down what the sea writes without missing a day, and build our predictions on that record.
The water here moves differently with each season. For as long as a bottle stays in the sea, our measuring never stops.
We predict the path time will take.
From 112,316 tasting records we learned how champagne changes over aging time. A model reads that change along six axes, and the pace at which it opens and the way bubbles persist are refined by the laws of physics and chemistry. From it we draw a single 36-month curve. We promise no better path. Only a different one from the land.
The same time, a different shape
Six axes · land → 12 months undersea, predictedAll six axes move together and settle into a new balance. Neither better nor worse. Another balance, made by the sea.
On retrieval day, we are put to the test.
We predict how the sea will age each bottle and write it down before retrieval. On the day, we set it beside an identical bottle kept on land and check prediction against reality through a comparative tasting.
Whether we were right is not ours to say. The verdict belongs to the sea. The results are published as they are.
Next retrieval · Winter 2026
What is verified recalibrates the model.
Every verification flows back into the model. Three years of checking built today's predictions, and each retrieval makes the next one sharper. The record does not stay inside the system — it stays with each bottle, as a certificate.
A prediction sharpened with every retrieval
We write the prediction before heading out to sea. On the day of retrieval, we lay that prediction beside the measurement. The gap rewrites the next prediction, and with each retrieval the two draw closer. So the prediction we write on the next bottle grows more accurate every year.
That record settles into each bottle
Once verified, the history becomes a certificate for every bottle. Hold your phone close and the immersion coordinates, depth, temperature and time spent at sea open up. No two records are alike.
“Writing down our prediction and heading out to sea feels like sitting an exam. The grading is not ours to do. Accepting that is the whole of this work.”
This record is published every year.
Nothing embellished. Kept exactly as it was.
What we record
Immersion data, sea conditions and verification results, each written down with its date.
This record is published every year.
Immersion data, the sea's conditions, verification results, all kept with their dates. Nothing embellished, only what happened.
Our prediction is written. Now it is the sea's turn to answer.
Be the first to meet each new edition, and keep the record of its time at sea for life.
Seats open only as many as the bottles prepared.
