Tsen Chi Cha is a oolong tea produced in Amoy China. This version is the Sea Dyke brand. This tea is packed in a metal foil bag and packaged in a paper box. This tea had been produced for many years by Sea Dyke and is available in many South East Asian countries. They are commonly found in Chinese tea shops or Chinese emporiums. I remembered I saw this tea at a Chinese tea shop in San Francisco and Toronto as well.
I was in at Yue Hwa Emporium, Hong Kong last year browsing at the Sea Dyke tea section when an elderly man came to the same aisle and picked up 2 boxes of this tea. I asked him why he had chosen this tea. He replied that he drank lots of tea (oolong, puerh, longqing), but because he lived in a very small apartment, he only had a small shelf for his tea. When he had finished his stash, say oolong, he would replace them. He mentioned he does not buy to store his tea long term but buy to drink. He smiled and went off to pay, not before telling me that this tea was good. I bought a box of this tea.
This tea brews up 5 good infusions. It is high roasted and has a taste and aroma like a hybrid shui hsien and a tie kuan yin. Nothing sophisticated or extraordinary but the traditional roast and comforting aroma made this tea a value for money purchase. I can understand, when I sipped this tea at home, why the Hong Kong gentleman liked this oolong.
