Biodynamic wine is an all-natural approach to viticulture that emphasizes the unique character of each individual farm's soil and climate. In the wine world, the distinctness of each different soil is called terroir (related to the Latin word terra, "earth"). Often wines are Demeter Certified, guaranteeing that they...

Biodynamic wine begins with grapes grown through whole-farm vineyard care. Growers work with compost, biodiversity, and close observation to cultivate the character of each vineyard's soil and climate, often called terroir. In the United States, a Demeter-certified wine also follows the applicable farm, processing, and labeling standards, connecting vineyard and finished bottle.
Biodynamic preparations are part of that living-farm practice. Horn Manure (BD 500) is used as a soil spray in vineyard care, alongside compost, ground cover, and other work that supports living soil and roots.
Horn Silica (BD 501) is a foliar preparation used as vines grow and grapes ripen. Growers fit its timing to the vineyard and current weather.
The compost preparations (BD 502–507) bring yarrow, chamomile, nettle, oak bark, dandelion, and valerian preparations into the compost program that returns organic matter to the vineyard soil.
Equisetum arvense (BD 508) is used as a fresh foliar tea in humid-season vineyard care. Together, these practices connect soil, foliage, compost, and careful observation of the vines.
Biodynamic wine begins with grapes grown through whole-farm vineyard care, including compost, biodiversity, and biodynamic preparations. A Demeter-certified bottle also meets applicable winemaking and labeling standards.
What does Demeter certification mean for a wine bottle?
For a U.S. Demeter-certified wine, the grapes, winery processing, and label meet the applicable Demeter standards.
How is Horn Manure used in a biodynamic vineyard?
Growers apply BD 500 (Horn Manure) as a soil spray to support living vineyard soil within a whole-farm biodynamic program.
Which preparations does this article introduce for vineyard care?
It introduces BD 500 for soil, BD 501 for foliage, BD 502–507 for compost, and Equisetum (BD 508) for humid-season foliage care.
