Abstract

The invention belongs to the field of processing of tea leaves, and relates to a processing method of Laoshan green tea, and particularly relates to a processing method of clean and fresh type high-grade special Laoshan green tea capable of erecting after being brewed. The processing method comprises the following steps of picking, spreading, deactivation of enzymes, strip tidying, spreading for cooling and moistening regain, primary baking, secondary spreading for cooling and moistening regain, and re-baking to be enough dry, wherein a fresh leaf which is subjected to the deactivation of enzymes is directly subjected to the treatment of the strip tidying without being subjected to the spreading for cooling and temperature lowering; after the primary baking, the leaf is subjected to the secondary spreading for cooling and moistening regain; the re-baking to be enough dry is carried out by selecting and using a temperature which is lower than that of the primary baking. The Laoshan green tea processed through the processing method of the Laoshan green tea is tall and graceful in appearance, green and sleek in color and luster, apricot-green and transparent in liquor color, clean and fresh in fragrance, fresh and mellow in taste, and bright, complete and lobate in brewed leaf; after being brewed, the tea leaf erectly spreads in a cup and is high in viewing and admiring performance; the contents of an amino acid and a vitamin C which are beneficial to a human body are higher than those of ordinary Laoshan green tea.
