The invention relates to the field of brewed vinegar, in particular to glutinous rice fermented wine-based flavor enhanced brewed vinegar and a preparation method thereof, and aims to solve the problems that existing glutinous rice vinegar is generally low in total acid content, insufficient in non-volatile acid content and simple in flavor level. The brewed vinegar takes a mixture of white glutinous rice and black glutinous rice as a main raw material, the white glutinous rice provides the most basic sweet taste and alcohol taste, the addition of the black glutinous rice can greatly enrich flavor levels, a pineapple extract and a rhizoma polygonati extract are added, pineapples are rich in malic acid and citric acid, and the organic acids are introduced into a system in an alcoholic fermentation stage, so that the taste of the brewed vinegar is improved. The rhizoma polygonati extract contains a large amount of polysaccharide substances and can provide nutrient substances for yeast fermentation, saponin and phenolic acid substances in the rhizoma polygonati extract have the capability of scavenging free radicals and can inhibit oxidation of unsaturated fatty acid and degradation of pigments in vinegar, and the rhizoma polygonati extract can be used for preparing the fruit vinegar. The product flavor stability is prolonged.
