Biodynamic farming is next-level organic. It builds on the practices used in organic farming and incorporates the rhythms of the Earth, moon, and stars to help dictate what goes on in the vineyard. The philosophy was developed by Rudolf Steiner in the early 20th century. Steiner created nine different preparations using herbs, quartz, and humus (the latter two are used in the famous cow horn treatments) to fertilize the soil throughout the year. He devised a calendar based on the movement of the moon through the signs of the zodiac to determine when to prune, fertilize, and harvest.
