Production technology of lotus seed spirit

The invention discloses a production technology of lotus seed spirit, belonging to the technical field of wine brewing. The production technology comprises steps of (1) preparing spirit starter: washing, soaking and boiling the grain to be well cooked; then cooling, inoculating pure mold starter, cultivating for 40-60 hours at 20DEG C-35DEG C, so as to prepare the finished product spirit starter; (2) preparing seeding yeast: uniformly mixing the spirit starter with water, adding yeast culture solution, cultivating for 5-7 days at 15DEG C-30DEG C so as to obtain mature seeding yeast; (3) fermenting: boiling, cooling and smashing the lotus seeds, then mixing with water uniformly so as to form a lotus seed-water mixture, adding the mature seeding yeast, fermenting for 7-30 days at 15DEG C-35DEG C so as to obtain mature fermented undecanted wine; and (4) sequentially liquid distilling, ageing, blending, filtering the mature fermented undecanted wine so as to obtain the lotus seed spirit. The preparation method is convenient to operate, has high use ratio of raw material starch, has stable processes, saves energy, and can prepare the lotus seed spirit with pure fragrance and taste.
