The invention discloses a Pu'er tea
yeast fermentation technology. The technology comprises the following steps: (1) cleaning, (2)
fermentation, (3) tea overturning, (4) stacking, (5) natural
drying and (6) refining. According to the invention, Pu'er tea leaves are fermented in a
fermentation room with the assistance of
yeast, so that the
cell membrane permeability of the Pu'er tea is increased, the enzymatic oxidation of polyphenols substances is promoted, the quality of the Pu'er tea is enhanced and the contents of water extracts, tea
pigment, amino-acid and the like of the Pu'er tea are increased; as the Pu'er tea is produced through the adoption of the
yeast fermentation technology, the fermentation time is distinctly shortened and the production efficiency is improved. The Pu'er tea, produced by adopting the
yeast fermentation technology, is bright in color, full in shape, attractive in appearance, rich and strong in scent and rich in
nutrition; the Pu'er tea water has a sweet and faint fragrance and is palatable; color, fragrance, taste, shape and
nutrition of the original tea leaves are kept.
