Description
Acetic acid fermentation of naturally fermented palm sap (toddy) yields a complex, fruity vinegar.
Technical
Saccharomyces cerevisiae and wild yeasts first ferment palm sap sugars into ethanol (3-5% ABV), followed by Acetobacter aceti converting ethanol to acetic acid (4-6% concentration).
Culinary Significance
Adds bright acidity with tropical fruit undertones to dipping sauces, marinades, and pickles.
