Embodiment 1

[0043] A kind of preparation method of rooibos tea wine as the embodiment of the present invention, described method comprises the following steps:

[0044] Accurately weigh 10g of rooibos tea, add it to a 500mL Erlenmeyer flask, inject 300mL of deionized water, then add 10wt.% white sugar, add 3wt.% ammonium sulfate, shake at room temperature to dissolve the white sugar, use Adjust the pH of the solution to 6.0 with citric acid or sodium hydroxide, sterilize at 121°C for 30 minutes in a high-pressure steam sterilizer, cool to room temperature, and inoculate yeast (with a concentration of 4×10 7 each / mL), the inoculum amount was 3%, and they were respectively placed in a constant temperature incubator at 22° C. to 30° C. for constant temperature fermentation for 7 days. After the fermentation was completed, they were pasteurized for 30 minutes to remove solid insolubles to obtain the rooibos tea wine.
