When I first tasted a champagne from the Aube, I was surprised. This wine felt different — fuller, rounder, less angular than the classic chalk champagnes of the Marne. The reason lies literally underground: Kimmeridge marl, a fascinating soil that shapes the Côte des Bar and is increasingly drawing the attention of the champagne world.
What is Kimmeridge Marl?
Kimmeridge marl is a geological wonder from the Upper Jurassic period, about 150 million years old. This soil formation consists of a unique mixture of limestone and clay, enriched with fossilized marine organisms — particularly oyster shells and other sea creatures from that era.
The name comes from the English coast at Kimmeridge Bay in Dorset, where this formation was first scientifically described. In Champagne, this soil is found mainly in the Aube, specifically in the Côte des Bar, where it makes up about 70% of the vineyard area.
The Composition in Detail
| Component | Percentage | Properties |
|---|---|---|
| Limestone | 60-70% | Water storage, minerality |
| Clay | 25-35% | Nutrient storage, water retention |
| Fossils | 5-10% | Additional minerals, complexity |
How Does Kimmeridge Marl Differ from Marne's Chalk Soil?
The difference between the soils of the Aube and the Marne is fundamental and significantly shapes the character of the resulting champagnes.
Marne's Chalk Soil: The Classic Champagne Soil
In the Marne, particularly in the Côte des Blancs and Montagne de Reims, chalk from the Campanian (Upper Cretaceous) dominates. This pure, white chalk is:
- Highly porous: Excellent drainage while maintaining water storage
- Mineral-poor: Reduced nutrient supply leads to concentrated aromas
- pH-neutral: Ideal conditions for elegant, delicate wines
Aube's Kimmeridge Marl: The Powerful Alternative
Kimmeridge marl, on the other hand, offers:
- Clay content: Better water storage in dry years
- Mineral richness: Higher content of calcium, magnesium, and trace elements
- Fossil components: Additional minerals from fossilized marine organisms
- Heat storage: The clay content stores heat better than pure chalk
What Influence Does Kimmeridge Marl Have on Champagne Style?
The effects of Kimmeridge marl on champagne style are clearly perceptible and make Aube champagnes a distinct style category.
Fullness and Body
Champagnes from Kimmeridge soils show pronounced fullness on the palate. The higher mineral content and better nutrient supply from the clay component lead to:
- Denser textures
- Rounder mouthfeel
- Less angular acid structures
- Longer persistence on the palate

The fossil components of Kimmeridge marl bring a maritime note to the champagnes:
- Subtle saline nuances
- Mineral depth with iodine-like hints
- More complex tertiary aromas with longer aging
Grape Variety Expression
Pinot Noir particularly benefits from Kimmeridge soils:
- Fuller fruit expression
- Silkier tannin structure
- Better color stability in Rosé champagnes
Why Is the Aube Finding Increasing Recognition?
The renaissance of the Aube in the champagne world is no coincidence, but the result of several factors that put Kimmeridge marl in the spotlight.
Climate Change as Catalyst
With rising temperatures, the cooler sites of the Aube become increasingly attractive. Kimmeridge marl offers crucial advantages:
- Water storage: The clay content helps during longer dry periods
- Temperature regulation: Better buffering of extreme weather conditions
- Later ripening: Longer growing season for more complex aromas
Quality Revolution of Aube Producers
A new generation of winemakers in the Aube has recognized the potential of Kimmeridge soils:
- More precise vineyard work
- Selective hand harvesting
- Gentle vinification to emphasize terroir characteristics
- Longer lees aging for more complexity
Changed Consumer Preferences
The market increasingly demands individual, terroir-driven champagnes. The Kimmeridge champagnes of the Aube offer:
- Recognizable style
- Excellent value for money
- Authentic terroir expression
- Alternative to classic chalk champagnes

Conclusion: Kimmeridge Marl as the Future of Champagne
The Kimmeridge marl of the Aube is more than just a geological curiosity — it is a key to the diversity of Champagne. These 150-million-year-old soils produce champagnes with distinctive character: fuller, rounder, and more mineralogically complex than their chalk counterparts from the Marne.
For me as a champagne enthusiast, the Aube champagnes from Kimmeridge soils are a fascinating discovery. They show that great champagnes don't only come from the famous chalk soils of the Côte des Blancs. Kimmeridge marl is writing a new chapter in the history of Champagne — and I'm excited to see what surprises these ancient soils will bring us next.
