Champagne Leclerc Briant, Épernay. The house was founded in 1872.

Champagne's economics run on blending, volume and consistency — producing a bottle that tastes the same every year regardless of what the season did. Biodynamic farming runs on the opposite instinct entirely, which is why the two so rarely appear together.

Leclerc Briant has been making the counter-argument since René Leclerc began moving away from conventional chemistry in the 1960s, a process Frédéric Zeimett completed with full Demeter biodynamic certification. The vineyards are farmed without synthetic chemistry across Cumières and Hautvillers on the Vallée de la Marne, and on chalk and clay in the Grand Cru village of Aÿ, with composting, cover cropping and preparations applied on a lunar calendar. The yields are measurably lower and the mineral tension is the return on that.

Leclerc Briant
The Abyss cuvée spends fifteen months at sixty metres under the Atlantic, off the island of Ouessant.

The Abyss is bottled with zero dosage: no sugar at the end, so nothing is covering anything. Dosage is the standard last adjustment in Champagne and the easiest place to correct a wine; leaving it out removes the safety net entirely. Disgorged in pressure-sealed tanks fifty metres underwater off Brittany, it has drawn 95 points from Wine Advocate and the collector attention that arrives when a genuinely good wine also has a story people want to repeat. The Blanc de Blancs and Extra Brut carry the same farming at considerably more accessible prices.

Around eight percent of Champagne's vineyards are certified organic. In that context, a fully biodynamic house is not a stylistic preference but a structural outlier, and it is worth knowing they exist before the next occasion that calls for a cork.

“What is important for me is not the reason why. It is the results.”

Why it’s remarkable

The 1960s
organic in Champagne, decades before the region took it seriously
Bertrand Leclerc was farming organically in the 1960s, when the idea had almost no standing in Champagne at all. His son Pascal took the house biodynamic in the late 1980s. Three generations of this predates the fashion by a very long way.
60 metres down
the Abyss cuvée is aged on the Atlantic seabed
Fifteen months at sixty metres off Ouessant, off the Breton coast, at a depth where the water pressure outside the bottle matches the pressure of the champagne inside it. Constant temperature, complete darkness, no oxygen. Jestin’s argument is that the movement of the ocean keeps the wine in permanent dynamisation.
Zero dosage
no sugar at the end, so nothing is covering anything
The Abyss is bottled brut zero. Dosage is the standard last adjustment in Champagne and the easiest place to correct a wine; leaving it out removes the safety net entirely.
Scope to confirm
how much of the production the Demeter mark covers
Demeter certification is on record for this house from 2003. Some published accounts describe it as covering part of the production rather than all of it, and we have not yet been able to confirm which is right. Worth knowing if you are buying a specific cuvée on the strength of the mark.
