Organic wines are made from grapes that are grown without the use of synthetic fertilizers, pesticides, herbicides, or genetically modified organisms (GMOs). Organic winemaking practices extend beyond the vineyard and include restrictions on the use of sulfites during the winemaking process. While organic certification varies by country, organic wines generally adhere to strict regulations to ensure that the grapes are cultivated using organic methods.
Biodynamic winemaking takes organic principles a step further, considering the vineyard as an interconnected ecosystem. Biodynamic farmers use organic practices but also follow a holistic approach that incorporates lunar and celestial cycles. They treat the vineyard as a self-sustaining entity and focus on enhancing soil health and biodiversity. Biodynamic practices may involve the use of specific herbal and mineral preparations in vineyard treatments and following a biodynamic calendar for planting, pruning, and harvesting.
Natural wines are often considered the least regulated of the three categories. The term "natural" generally refers to minimal intervention winemaking. Natural winemakers strive to use minimal additives and technological manipulations during the winemaking process, allowing the wine to express the true characteristics of the grapes and terroir. Natural wines may be made from organic or biodynamic grapes, but the focus is more on the winemaking philosophy rather than certification.
