Sustainability: Organic, Biodynamic, Natural Wine

Three distinctly different concepts are often confused. Organic farming prohibits synthetic pesticides and fertilisers but allows approved copper and sulphur; the EU organic certification (EU leaf) regulates farming and now also winemaking additives. Biodynamic farming following Rudolf Steiner's principles treats the farm as a self-sustaining organism and uses cosmic calendars and preparations (e.g. horn manure 500). Demeter is the dominant certifier. Natural wine lacks a global legal definition — generally it means chemical-free grape growing and minimal SO₂ with no cellar additions. Results vary enormously and are intensely debated within the wine world.
