Tea plantations

The Alishan Oolong mountain tea (Chinese: 乌龙茶, wulong cha in pinyin) is grown at altitudes ranging between 1000m and 2000m in the Alishan region. Here the climate is humid with low temperatures and the air is misty between dawn and dusk. The Alishan Oolong tea is harvested in April, May to August, and September, late in the season when the leaves are larger and stronger, making them more suitable for the processing steps. The processing involves withering in the sun (or indoors if it rains) and oxidisation in bamboo trays. The leaves are then dried and stored in plastic bags. A final roasting step is needed to produce the Oolong tea. Generally speaking Oolong has less caffeine than black tea and more than green tea.
