How we scored it

Whole fermentation filtrate, no synthetic fragment; natural = 1.0

What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Produced by fermenting Saccharomyces yeast in a nutrient medium and then filtering out the cells. No petrochemical processing step is involved.
