In the concept of "Ink Grade" tea cake, there are two kinds of "Green Ink," one is "Grade A" (Jia Ji 甲級) and another one is "Grade B" (Yi Ji 乙級). These two grades did not indicate the one's quality is better than another, but was simply an indication of different batch of raw material at its time.
However, due to the naming effect, people often consider "Jia Ji / Grade A" as a better tea than "Grade B," so it was inevitable to see this reproduced version called "Grade A." This "Grade A" was made from clean Yi Wu material, making the whole cake having the powerful Yi Wu character after every brew.
