Lactic-acid and alcoholic fermentation of agave sap by native microbiota.
Technical
Conversion of agave fructans (inulin-type fructooligosaccharides) into fructose, then metabolized by wild yeasts (Saccharomyces cerevisiae, Kluyveromyces marxianus) and lactic acid bacteria (Lactobacillus spp., Leuconostoc spp.) producing ethanol, CO2, and polysaccharide mucilage.
Culinary Significance
Creates a viscous, slightly sour alcoholic beverage (2-8% ABV) with unique probiotic qualities.
