In 2015 I bought 2 cakes of this type in continental Europe from 2 different retailers. I’ll be addressing them as cake #1 and #2.
Aroma of both dry and wet leaves: #1- smoky and heavy smoke when wet while #2 slight camphor aroma
Taste: both cakes teas are copper colour, pleasant, smooth and slightly sweet. With #2 being a bit more rounded off in the mouth
Neifei: #1- none and #2- yes
Inside label: both yes but with differences and slightly different printing. #1 spelling: Chitsu pingcha, puerhcha. #2 spelling: Chitse bingcha, puechcha. Also the label of #1 is a lot more yellowish.
Leaves: #1 leaves tend to be smaller on top of the cake and they crumble a lot more with the centre of the cake unlike an iron cake. #2 leaves on top of the cake are larger and looser although the centre of the cake is very hard still almost like an iron cake. Overall appearance #1 is redder brown with #2 darker umber colour.
Wrapping: #1 was wrapped with a final flap across the diameter of the cake. #2 was wrapped radially with no final flap.
