This cake was produced by BaoZhuo specifically for 2006 Tea Expo in Malaysia. It was produced in famous Changtai Tea Factory same like many JingMeiTang teas. As you can see on the back of the wrapper, tea passed all bunch of checks and passed health and organic certifications. 
Taste: 
This tea was obviously produced for long term storage. Pile fermentation was done very lightly and some Sheng qualities are still obviously even after 20years. It’s not earthy but rather with aroma of sweet corn or rice husk with gentle round closing.
*each cake is roughly 350grams and wrappers might be little eaten up on some cakes.
