Stored in Malaysia since the 1950's, this top grade ('Ding Ji Yuan Du') Liu Bao, was originally imported to be drunk by the managers of the pewter mines. It is a higher grade than that usually made and imported to be drunk by the miners.
I've drunk this tea many times and can honestly say that it is the best Liu Bao tea I've tasted. It is often referred to by some Malaysian tea drinkers as "Red Mark's big brother", referring to the famous 1950's puerh tea. They like to joke a lot, so I never really believed them or took it seriously until one of them offered to back his words up. He brewed a very well stored 'Jia Ji' (top grade) 1950's Red Mark cake and this tea side by side and the difference was obvious. The Liu Bao was richer, smoother and thicker. The qi was stronger and the mouthfeel & aftertaste more refined. From then on, I haven't doubted it.
I realise that as a seller of this tea, the above story will be subject to doubt or criticism, but thought I'd share it nonetheless. What I can say without doubt is that this is a very fine quality Liu Bao tea & is a pleasure to drink.
I've included photos of this tea, featured in the book - "Lao Liu Bao Tu" (Pictures of Old Liu Bao), published by Chop Xiang Xing, Malaysia. There is only one batch of Pu Tian Gong Qing - it is generally accepted as being from the 1950's.
