Cooking wine and preparation method thereof

The invention provides cooking wine and a preparation method thereof. The preparation method comprises the following steps: S1, dipping and extracting spices by adopting first fermented wine to obtain a first mixture; s2, carrying out solid-liquid separation on the first mixture to obtain a spice extracting solution; s3, mixing and blending the second fermented wine, the spice extracting solution and table salt to obtain the cooking wine. According to the present invention, the first fermented wine is adopted to perform impregnation extraction on the spice, such that the first fermented wine and the spice are subjected to a reaction in advance, and solid-liquid separation is performed after the impregnation extraction is completed so as to separate the precipitate in advance, such that the initial turbidity of the finally obtained cooking wine is low; and after the spice extracting solution obtained by dipping and extracting is mixed with the second fermented wine again, precipitates are not easy to generate
