Dynamisation & application for wine expression & quality

The contribution, measured

65 /100

Time horizon: Ongoing

How it contributes

The quality of the 501 application is part of what growers associate with definition and expression in the wine.

Why this goal matters

Many growers adopt biodynamics for the expression they attribute to the wines: greater aromatic clarity, energy and sense of terroir. It is the most cited motivation among top estates that have taken up the practice.

These qualities are, by nature, sensory and hard to quantify. What can be managed and documented is the programme — silica preparations, calendar work, cellar choices — and its relationship to tastings and analyses over time.

Market & certification: Wine expression is the main commercial argument of top biodynamic viticulture.

How to apply the practice

  1. 1Dynamise the preparation in water for ~1 hour.
  2. 2Apply right after, with the right droplet (coarse on soil, fine on canopy).
  3. 3Respect the time of day suited to each preparation.
  4. 4Log preparation, rate, time and plot.

Frequently asked

Can dynamisation be mechanical?

Yes — there are mechanical dynamisers that reproduce the vortex and reversal, useful over larger areas, as long as they respect the method.

Why does the time of day matter?

500 and CPP are applied at day’s end on the soil; 501 early in the morning on the canopy. It is part of the biodynamic application method.
