What is Biodynamic Wine?

Biodynamic wine is produced using a holistic farming approach that treats the vineyard as a self-sustaining ecosystem. Rooted in permaculture principles, biodynamics emphasizes the natural interactions between plants, animals, and soil, fostering biodiversity and long-term sustainability.

Like organic wine, biodynamic wine is made without synthetic chemicals or commercial additives, including lab-grown yeasts. However, some biodynamic wines still allow for filtration and small amounts of sulfites. That’s why, at Caverna do Vinho, we carefully select wines that are both biodynamic and fully natural—ensuring the purest expression possible.

How Does Biodynamic Farming Work?

Biodynamic farming goes beyond organic methods, using natural preparations to enrich the soil and support vine health. This includes composting with manure, herbs, and minerals, sometimes enclosed in materials like cow horns or skulls to enhance microbial activity. Pesticides and artificial fertilizers are strictly avoided.

A key element of biodynamic viticulture is its connection to lunar and planetary cycles. Farmers follow an agricultural calendar based on celestial movements, timing vineyard tasks—such as pruning, planting, and harvesting—to align with the rhythms of nature.

Who Was Rudolf Steiner?

Rudolf Steiner (1861–1925) was an Austrian philosopher and social reformer who laid the foundations for biodynamic agriculture. In 1924, a group of farmers concerned about soil depletion sought his guidance. Steiner introduced a system of ecological and sustainable farming practices designed to improve soil fertility without chemical intervention. His approach remains the cornerstone of biodynamic viticulture today.
