Abstract

The invention relates to a preparation method capable of increasing fragrance of fermented black rice tea. Through first-stage fermentation, mellow fragrance and nutrients due to baijiu distiller ricefermentation are supplied to second-stage fermentation; meanwhile, by shortening the second-stage fermentation time, unpleasant smell and loss of anthocyanidin due to fermentation of black rice are solved; in addition, by adding red dates and Chinese wolfberry, the fragrance of the black rice tea can be improved to a higher level. The fermented black rice tea has a pleasant fragrance, mellow taste and abundant nutrients. After high-temperature sterilization, the black rice tea is free of addition of any chemical preservatives and fresh-keeping agents, thus actually achieving pure-natural quality.
