Tea farmer friend and his most large tea tree. Even though, he still sells the price on tea leaves from this individual tree lower as other old trees along with the market.
Harvest of this autumn.
Test on tea harvested and processed in different days. The earliest was in this Auguest. The latest was picked and processed in two days ago (around Oct. 10th)
At the end, I selected the best one of them which was picked around in the first week of Oct, though it is the most expensive one.
