I never heard of the China Puer Tea Research Institute (CPTR) , otherwise known as China Puer Tea Research institute Tea Seed Multiplication Farm of Simao/Puer Yunnan (CPTRTSMF), before, but I have desperately searching the internet for a puerh seller who has more tea from them (sadly I haven’t found any). Before I go on I should mention that I tend to prefer young prettier cakes; by this I mean cakes with more golds, yellows and silvers rather than greens and blues so I was biased for the grade 1 and 2 samples. I wonder will my preconceived notions be challenged with these. Or will my prejudices against the more homely teas be justified? Generally I don’t pay much attention to appearance with greens and oolongs, although I never said no to comely Long Jing or LiShan, and instead focus on aroma and taste.
