Pyroligneous Acid (Wood Vinegar / WS) — Fermented Inputs Recipe
Wood vinegar is the condensed smoke fraction from controlled biomass pyrolysis—distinct from culinary smoke flavorings. In disciplined KNF it is used in tiny dilutions for soil biology signaling—not choked into reservoir irrigation unchecked.

In disciplined KNF it is used in tiny dilutions for soil biology signaling—not choked into reservoir irrigation unchecked. This Fermented Inputs preparation is made with hardwood feedstock (kiln-dried chunks) and is a staple input in regenerative Korean Natural Farming — feeding soil biology instead of relying on synthetic fertilizers. It is one of 50+ free recipes we use daily at the IC SPICY nursery in Port Charlotte, Florida.
Ingredients
- per retort volume Hardwood feedstock (kiln-dried chunks)
- 1 Condensing train + heat-safe collection vessels
- 1 pH / density logging notebook
Steps
- Only proceed if local regulations and insurance cover small-batch pyrolysis.
- Fraction crude pyroligneous acid into light/middle/heavy cuts during cooling.
- Age 3–6 months vented so harsh phenolics mellow.
- Dilute 1:500–1:1,000 for exploratory soil drenches; never foliar-heavy raw.
- If sourcing retail pyroligneous acid, verify agricultural grade—not barbecue smokefluid.
Common questions
How long does Pyroligneous Acid (Wood Vinegar / WS) take to make?
Plan for about Batch-dependent from start to finish. Fermented and cultured inputs improve with proper timing, so follow the step schedule in the recipe rather than rushing stages.
When should I apply a Fermented Inputs input like this?
Match the input to the plant's growth stage, per Master Cho's nutritive cycle theory: vegetative-stage plants favor growth inputs like FPJ and FAA, while flowering and fruiting plants favor WCA and FFJ. Apply early morning or late evening, and never in strong midday sun.
Is this safe for organic or no-spray gardens?
Yes — like all IC SPICY CookBook recipes, this uses only biological and food-grade ingredients with zero synthetic fertilizers or pesticides. Always label your jars, use clean tools, and do a small test application before treating every plant.
