Biodynamic fermentation in the egg shape corresponds to the golden ratio without corners and edges. Wine, must and beer can move freely during the fermentation phase and storage. This makes the process gentler and allows for full development.
The idea of fermentation or maturation in the egg is a return to ancient methods but with new materials. Even in ancient times, alcohol was matured in egg-shaped amphorae. After successful tests with egg-shaped fermentation containers made of concrete for winemaking in recent years, Speidel has now developed the fermentation egg made of food-safe polyethylene.
The oxygen permeability of the food-safe plastic allows an even influence of oxygen and thus ensures an ideal process of fermentation and maturation. After fermentation, the smooth inner surface is very easy to clean.
