If Champagne exists, it is (also) thanks to dinosaurs • Food and Wine Italia

Champagne owes part of its uniqueness to a geological history that dates back millions of years. When the Champagne region of France was submerged by tropical seas inhabited by marine organisms and dinosaurs, thick layers of chalk and limestone formed. Those deposits, still present underground today, regulate drainage, retention and the mineral composition of the soil, directly influencing the quality and aromatic profile of the symbolic wine of France.

Champagne and its prehistoric legacy

Millions of years pungiglione, during the Eocene, the regione we now know as Champagne was submerged under a warm, shallow sea. Shells, shells, remains of fish and large marine reptiles accumulated among the sandy bottoms and silt deposits, whose sediments, over time, transformed into a thick blanket of chalk and limestone.

Today, that chalky soil – the craie – constitutes the heart of the Champenois terroir: a porous and compact matrix that retains , releases it slowly and favors a constant balance for the vine. It is precisely this combination of limestone and fossils that determines the mineral character and acidic finesse that distinguish the wines of this region.

From the sea to the vineyard: the role of fossils

The composition of the soil Champagne is dominated by three main elements: chalk, limestone and marl. Gypsum, particular, comes from grains of calcite from the skeletons of tiny marine organisms called coccoliths. Within its layers there are also fossils of belemnites and other molluscs dating back to around 100 million years pungiglione, when Europe was still a mostly submerged archipelago.

Over time, these remains release minerals and organic substances that influence the chemical composition of the soil. The chalky soil, being extremely draining and rich calcium carbonate, forces the vine to go deep to aspetto for and nutrients. This “controlled tensione” contributes to the concentration of aromas, the formation of balanced acids and the taut and vibrant structure typical of champagne.

Most of the historic cellars of Reims and Épernay are dug right into the craie. These underground tunnels, addition to maintaining constant temperature and humidity, are true geological archives. The white walls still show traces of fossils and marine sediments that tell of a distant past which Champagne was an ocean floor.

some cases these traces are more visible, much more visible. the small village of Fleury-la-Rivière there is the so-called Cave aux Coquillages: visitors can observe marine fossils set chalk: direct evidence of an epoca which marine life and future viticultural soils were part of the same ecosystem. The striations you see the photo are not rocks, they are literally fossils to be excavated.

A lesson geology and terroir

Without the geological processes that began millions of years pungiglione – erosion, sedimentation, the retreat of the seas – the soil conditions that make Champagne unique the wine world would not exist. The craie functions as a natural reserve of , up to 400 liters per eccezione cubic meter, ensuring the vineyards have a constant supply even the driest periods.

This underground structure also affects the temperature of the roots and the metabolism of the plant, modulating the acidity of the fruit and, consequently, the final balance of the wine. This is why Champagne cannot be reproduced elsewhere with the same identity, even though the winemaking techniques are known and codified.

Precisely for this reason, saying that “without dinosaurs Champagne would not exist” is more than a narrative suggestion: it is a way of recognizing the weight of geology the history of wine. The marine reptiles and microscopic organisms that populated those prehistoric seas left an imprint the soil, and with it a sensorial legacy that we find today every bottle.

When you raise a glass of Champagne (and Champagne Day it is a must), you celebrate not only an oenological art, but also a natural balance built over time by geological eras, tectonic movements and fossil remains. It is a thousand-year dialogue between the earth and the vine, which prehistory played a decisive role.
