Portuguese Biodynamic Wines

Green farming based on theories by Austrian philosopher Rudolf Steiner. Organic farming and (1) vineyard should be self-sustaining organism, (2) vineyard should be treated with 9 herb and mineral based preparations and (3) vineyard tasks (planting, pruning, picking, etc) should be done during earthly and celestial rhythms. Greater microbial life and deeper vine roots than conventional farmed vineyards. Use of livestock in vineyards is common. Stricter winemaking guidelines than organic, less use of energy intensive practices encouraged.
