(Vogue) - We look to the moon and planets for guidance about a lot these days, from when to start a new project and end a toxic relationship, to why we might be in an emotional funk (Mercury must be in retrograde. But should you consider lunar forces when drinking wine? A number of winemakers believe the movement of the moon should guide us in grape-picking, and drinking.

It’s part of biodynamic winemaking, a style that calls for a combination of rigorous farming regulations—no pesticides or chemicals allowed—and a more holistic, spiritual approach (you may have heard about the more sensational mystical stuff here—something about burying cow horns in the manure or special compost preparations that sound more like witch’s brew). Biodynamic winemakers use moon methods—based on ideologies developed by Austrian philosopher Rudolf Steiner and his student-turned-biodynamic leader Maria Thun in the 1920s—to determine when to prune, rack, and bottle their wines.
