The origin. The climate in China is heterogeneous and in different regions tea growing conditions vary. It grows on diverse soils, at different altitudes, in diverging temperature ranges therefore its leaf accumulates versatile substances affecting the taste and aroma of the tea. For instance in Yunnan the large leaf trees are in abundance while in Fujian small leaf tea bushes prevail. Cultivation environment. There are certain tea types that are grown under specific conditions. For example, the Emerald spirals of spring are planted among the fruit trees to tincture the tea leaf fragrance with fruity notes which tenderly unveil themselves at brewing. On the same mountain - at its foot, in the middle and at the top - the taste of the growing tea will differ and its value will differ as well. Tea cultivars. China has both tea trees reaching over 20 meters in height and tea bushes. Tea leafs are also distinguished as wide, narrow, round and small. There are special bushes for white tea with thick white hairs. The bush of Tie Guan Yin has given the name to the whole range of Oolongs distinguished by heavy, harsh textured leaf. These are a few examples illustrating that each type of tea requires the specific tea plant cultivar. Please, do not get confused. Green tea can be produced from any tea bush as «green» implies the technology of leaf processing. However the Dragon Well from Xi Hu lake can be made only from specific bushes growing in the specific location. Harvest time. Each tea type has the respective harvest time. Sometimes different teas can be produced from the same plant: white tea of buds in February, red tea of tips in March and green tea of leaves in April. Yet only one type of tea is produced after all distinguished by quality grades, which depend on the period of its harvesting. Leaves for processing. Each type of tea requires the specific leaf of the tea plant. There are teas produced exceptionally of buds, others - of tips (the bud and one-two leaves), some are made of large leaves, while production of others uses whole offshoots with several leaves. Technologists give clear instructions to the gatherers what leaves should be flushed today for tea production.
