What it meansThe certification mark for biodynamic agriculture. Stricter than any government organic standard: it covers the entire farm as a closed ecosystem, follows a planting calendar tied to lunar/solar cycles, and bans many practices the baseline organic rules permit.Germany's national organic mark, owned by the Federal Ministry of Food and Agriculture. Sits alongside the EU Leaf on most German organic packaging since 2001. Same standard as the EU Leaf — Bio-Siegel is the brand consumers recognise.The strictest, most widely-recognised standard for organic textiles. Covers the full supply chain from organic fibre to finished garment, with environmental AND social criteria.

  • All organic standards PLUS biodynamic preparations and whole-farm planning.
  • Whole-farm certification (not single fields/products).
  • Annual on-site inspection by Demeter-accredited inspectors.
  • Animal welfare standards stricter than baseline organic.
  • EU baseline organic (EU 2018/848).
  • Annual on-site inspection by accredited German certifier.

Does NOT
  • Biodynamic philosophy includes esoteric elements (lunar planting, herbal preparations) that many scientists view as non-evidence-based — the agronomic outcomes are still good, the underlying claims about cosmic forces are not testable.
  • Same standard as the EU Leaf — not stricter.
  • Doesn't cover non-textile components (zips, buttons, prints) beyond the chemical-restriction list.
