What is a Concrete Egg?

- A concrete egg is a fermentation and aging vessel made of concrete, shaped like an egg.

 

Why do we choose to use them?

 

⦿ Natural Mixing & Homogeneous Fermentation: The egg shape creates convection currents during fermentation, keeping lees (yeast solids) in suspension.

⦿ Micro-Oxygenation Without Oak Influence: Unlike stainless steel, concrete is porous, allowing controlled oxygen exchange.

⦿ Temperature Stability: Thick concrete walls provide natural insulation, reducing temperature fluctuations.

⦿ Purity of Fruit Expression: Preserves delicate fruit characteristics and minerality.

⦿ Sustainable & Durable: Long lifespan compared to oak barrels.
