Composite fermentation inoculant and application thereof

The invention provides a compound fermentation inoculant and application thereof, and the compound fermentation inoculant comprises at least one of a heat-resistant kluyveromyces cerevisiae strain and a culture thereof, an issatchenkia orientalis strain and a culture thereof, and a saccharomyces cerevisiae strain and a culture thereof, the viable count in the heat-resistant kluyveromyces cerevisiae strain and the culture thereof, the viable count in the issatchenkia orientalis strain and the culture thereof, and the viable count in the saccharomyces cerevisiae strain and the culture thereof are 80-20 billion CFU/g, 80-20 billion CFU/g and 150-30 billion CFU/g respectively. The microbial inoculum can effectively solve the prominent production problems of insufficient aroma, disordered taste, poor quality and the like in fruit wine products such as Chinese wolfberry fruits, hawthorn fruits, grapes and the like, the alcoholic strength and the fermentation degree are not obviously influenced when the fruit wine p
