We carry a wide range of regionally milled flours in store, some of which are organic, some biodynamic and some sustainable. We’ve had a few very reasonable questions about the difference between them all – so here’s out ultimate guide to Kombu’s bulk flours 👩‍🍳

🍞 Organic Flour & Grain 👩‍🍳

When we say a product is organic, it means it’s been grown and produced following strict Australian standards for organic and biodynamic farming. Certified organic farms avoid synthetic fertilisers, pesticides, and GMOs, instead relying on natural methods like crop rotation, composting, and healthy soil management. The focus is on supporting soil life, improving nutrient cycles, and creating balanced, resilient farm ecosystems.

🍞 Biodynamic Flour & Grain 👩‍🍳

Biodynamic farming is a special form of organic agriculture developed in the 1920s by Rudolf Steiner. It shares the same commitment to natural, chemical-free farming but goes a step further by treating the entire farm as a living system. Biodynamic farmers use specific soil preparations—like “Preparation 500”—and time their activities with natural cycles to strengthen soil life and vitality. The result is soil teeming with beneficial microbes, fungi, and insects, creating a deeply interconnected, self-sustaining environment.

🍞 Certified Sustainable Flour & Grain 👩‍🍳

Certified Sustainable is a newer Australian standard for farms committed to environmentally responsible and ethical practices. It focuses on soil health, biodiversity, and residue-free farming, while allowing some flexibility for growers transitioning from conventional systems. Unlike organic certification, a small number of low-risk synthetic inputs may be used if they meet strict environmental guidelines. It’s a practical, transparent way to support sustainable food production—especially for farmers adapting to changing climates and regional conditions.
