Essentially, biodynamics is a holistic view of agriculture. It believes that all things in the universe are interconnected. Like organic wines, biodynamic wines contain no chemicals and additives throughout the winemaking process, they just take things a step further.
Biodynamic practices occur primarily in the vineyard before winemaking ever happens. All the various tasks, from planting, pruning, to harvesting, are regulated by a special biodynamic calendar. 

The calendar was originally devised by the ‘high priestess’ of Biodynamics, Maria Thun, who divided days into four categories: Root, Fruit, Flower, and Leaf Days. Each of these holds special properties and has specific benefits in winemaking.

To be certified under either of the two biodynamic wine certifications – Demeter and Biodyvin – vineyards must maintain exceptional soil health and vintners must time their planting schedules with lunar cycles to ensure the best agricultural health.
