The invention discloses a production method of chaff-free solid Xiaoqu liquor. Specifically, the method is characterized by comprising the following steps: a, using high-quality glutinous red sorghum as a raw material; b, soaking the sorghum in water at 65-70 DEG C until the sorghum is absorbed with the water uniformly and the core of the sorghum is wet, and removing tannin and ash; c, conducting primary steaming for 3min; d, suffocating the sorghum in water at 80 DEG C; e, re-steaming the sorghum for 120min until grains become soft and cooked, wherein a starch opening rate is high and a moisture content is 50-53%; f, discharging the grains out of a steamer and spreading the grains until the grains become cooled, wherein a yeast adding temperature is 35-40 DEG C and a yeast dosage is 0.3-0.6%; g, collecting the grains in a box; h, conducting cultivation and saccharification until the temperature of the box is uniform, no infectious microbe is saccharified, rhizopus bran koji and the yeast grow normally and 2.5-3% of raw sugar is discharged out of the box; i, blending the grains according to a ratio of 1 to 3.5, wherein an acidity is greater than or identical to 1.2; j, conducting fermentation, wherein a barrel feeding temperature control point is at 16-20 DEG C and a fermentation cycle lasts for 35-45d; k, conducting distillation, wherein an alcohol concentration control point is 60-65VOL%; l, implementing storage; m, conducting blending; and n, conducting packaging and discharging an obtained product out of a factory.
