The invention relates to low-fermentation-degree turbid wheat dry beer and a brewing method thereof. The barley malt and wheat malt are adopted as main raw materials which are added with a wheat gluten emulsion at certain proportion, and the turbid wheat beer is prepared by the steps of saccharification, fermentation and storage. In the invention, the wheat gluten solution after heating and alkaline hydrolysis treatment is applied to the preparation of wort for the first time, and protease is added in the wort preparation process to enhance the dissolution of the wheat gluten protein; by adding the treated wheat gluten emulsion, relative mass fraction of sugar in the wort can be reduced, and the obtained dry beer has the characteristics of low alcohol content, low fermentation degree, low content of residual sugar, high protein content, richer nutrition and more delicate and lasting foam; and moreover, the turbidity of the finished product of wine is remarkably raised, the turbidity is stable and lasting, the alcohol content is low, the protein content is high, and the content of residual sugar is lower than 5g/L.
