Embodiment 1

[0034] Take 100g of commercially available black tea for later use, then take fresh ginger, squeeze the juice, take 100g of ginger juice, mix it with the aforementioned commercially available black tea until uniform, place it in an airtight container for fermentation, and dry the fermented product to a water content of about 7%, namely Obtain product, named after ginger black tea I.

Embodiment 2

[0036] Take 1000g of commercially available black tea as the raw material; take fresh ginger, wash, squeeze the juice, filter, take 1250g of ginger juice, mix it evenly with the raw material, place it in a closed container, and vacuumize until the pressure inside the container is -0.05~-0.1MPa, The temperature is controlled at 34-36°C, and the fermentation is carried out at this temperature for 190-220 minutes. After the fermentation is completed, the product is dried to a water content of about 8%, and the product is obtained, which is named ginger black tea II.

Embodiment 3

[0038] According to the method of Comparative Example 1, but no ginger juice was added in the fermentation process, the finished black tea was prepared. Get 800g of this finished black tea as a raw material; get fresh ginger, wash, squeeze the juice, filter, get 400g of ginger juice, mix evenly with the raw material, place it in a closed container for fermentation, and dry the product after fermentation to a water content of about 8%, namely Obtain product, named after ginger black tea III.
