These ranges or values should be understood to include values close to these ranges or values. For numerical ranges, between the endpoint values of each range, between the endpoint values of each range and individual point values, and between individual point values can be combined with each other to obtain one or more new numerical ranges, and these numerical ranges should be regarded as specifically disclosed herein.

[0012] As a specific embodiment of the present invention: Step 1: Pretreatment of raw materials - Soak black rice until the water content reaches 35% (below 40% can prevent the dissolution of starch, and above 30% can ensure the saccharification efficiency); - Treat black beans with instantaneous steam at 120°C for 5 seconds (the enzyme inactivation rate ≥ 99% and the protein denaturation rate < 5%); - Treat black sesame seeds by combined cell wall breaking, using 400W ultrasonic wave (40kHz) + ball milling (particle size ≤ 50μm) for 5 minutes.

[0013] Step 2: Compound fermentation - Inoculate with a compound strain (aspergillus: rhizopus = 3:1); - Control the temperature during fermentation in stages: the first-stage fermentation is at 32°C for 72 hours (alcohol production period, control the pH at 4.2 - 4.5), and the second-stage fermentation is at 18°C for 15 days (ester synthesis period, the dissolved oxygen content ≤ 0.5mg / L); - Obtain the fermented stock solution A (alcohol content 8 - 15% vol).

[0014] Step 3: Treatment in stages - Take 50% of the fermented stock solution A for vacuum distillation (0.08MPa, 75°C) to obtain the distilled solution B (alcohol content 52% vol); - Reserve the remaining 50% of the fermented stock solution A for aging at low temperature.

[0015] Step 4: Medicinal material treatment - Establish a compatibility system of medicinal materials: monarch drug (15% longan), ministerial drugs (10% black wolfberry, 8% mulberry), assistant and guiding drugs (5% walnut, 3% black date) - Gradient extraction: Soak in three gradients with distillate B First time: 60% vol × 30 days (dissolve longan polysaccharide); Second time: 40% vol × 70 days (extract anthocyanins from black wolfberry); Third time: 40% vol × 70 days (dissolve resveratrol in mulberry).

[0016] Step 5: Blending and aging - Blend the medicinal material extract and fermented stock solution A at a ratio of 1:3 - 1:5; - Adopt double-stage aging in oak barrels and pottery jars; Aging in oak barrels for 30 days (adsorb tannins and increase vanillin content); Aging in pottery jars for 90 days (micro-oxygen aging to promote ester association); Obtain the finished product. After testing, the retention rate of anthocyanins is 82.3% (detected by UV-Vis method, 42% higher than traditional single fermentation), the extraction rate of flavonoids from medicinal materials is 78.6% (detected by HPLC, 31.2% higher than conventional soaking), and the comprehensive sensory score is 92.5 points (evaluated according to the GB / T 33405-2016 standard).

[0017] The main innovations of this preparation method are as follows: Trinary ratio system of black grains (40 - 60% black rice, 20 - 30% black beans, 10 - 20% black sesame) Staged treatment process: Simultaneously retain the fermented stock solution and the distillation extract.

[0018] Gradient medicinal material soaking technology: Adopt a two-phase extraction method of "distillation first and then soaking + low-temperature cold extraction".
