Pure-brewed cooking wine and production process thereof

The invention discloses pure-brewed cooking wine and a production process thereof. The spices are treated in two steps, essential oil is extracted in a supercritical mode, then residues are put into a wine fermentation tank to be further extracted, fragrance components are fully extracted, the problem that the spices are not fully extracted during follow-up blending is solved, and the essential oil obtained after supercritical extraction is adopted, so that sediment generated after filling due to spice extract liquid is avoided; meanwhile, through diatomite adsorption, generation of precipitates after later-stage blending is reduced; in addition, the red yeast rice is used for replacing caramel color, so that the color is reserved, the flavor is increased, and precipitation caused by the caramel color is avoided. According to the production process, the clarity of the purely brewed cooking wine can be effectively improved, and the prepared cooking wine product is good in color and luster and good in flavor. 本
