Abstract

The invention relates to sweet tea and a preparation method thereof. The preparation method of the sweet tea comprises following steps: (1), fresh leaves of rubus suavissimus are collected; (2), the fresh leaves of the rubus suavissimus are spread for 20-40 min, and spread leaves are obtained; (3), the spread leaves are subjected to fixation, and fixation leaves are obtained; (4), the fixation leaves are rolled, and rolled leaves are obtained; (5), the rolled leaves are subjected to first drying until the water content is 35%-40%, and primarily baked leaves are obtained; (6), the primarily baked leaves are subjected to sealed stacking for 3-4 h while the leaves are still hot, then the leaves are subjected to final firing until the water content reaches 5%-6%, and the sweet tea is obtained. According to the preparation method, the rolled leaves are subjected to first drying until certain water content is reached, and through combination of the thermochemical action during sealed stacking, the content of substances in a finished tea product is increased and the possible bitter and astringent taste is reduced; besides, the finished tea product has yellowish green and bright liquor color and tastes sweet, mellow and refreshing.

Description
