The invention belongs to the technical field of wine brewing, and provides highland barley whisky and a preparation method thereof. Specific Diqing purple highland barley at the altitude of 3159 m or above in the Shangri-La region of the Xiaoshan mountain vein of the south extension part of the Qinghai-Tibet Plateau is selected as a raw material, snow-field melt water subjected to reverse osmosis treatment is matched, a multi-strain composite process with Xiaoqu as a main component is adopted, saccharification and post-fermentation are combined into one-pot type fermentation, liquor is distilled by utilizing an Almarnek distiller, then the liquor is picked in a segmented mode, and the liquor is obtained. Extracting 60% voL fraction in the middle section; and aging the wine body for more than or equal to 1 year by utilizing a gunny jar, and then transferring into an oak barrel for aging for 2-5 years. The spraying mode is improved, the wine yield is increased, and the wine style is improved; original staged spreading is changed into continuous spraying type spreading, and the materials are uniformly sprayed to the surfaces of the raw materials during vibration sieve feeding, so that saccharification is more uniform and more thorough, and the liquor yield is improved by more than 5%. The utilization rate of starch and beta-glucan is increased, the wine yield is increased, and the wine body quality is improved.
