Lunar Calendars and Biodynamic Wine
Inside the controversial calendar that guides biodynamic cellars.
Biodynamic growers schedule their work by a calendar of root, leaf, flower and fruit days, tied to the position of the moon and stars. Skeptics call it astrology with a watering can; believers point to wines of unusual energy and clarity.
This entry lays out how the calendar actually works, what the science does and does not support, and why so many serious estates follow it anyway. You can decide for yourself whether the moon belongs in the cellar.
