In 2012, Yunnan Sourcing released a spring Wuliang tea that sold for $23/400g. Since then, Scott has pressed five more spring Wuliangs, most recently in 2018. This time it was priced at $43/400g, an effective price raise of87%. This post is an investigation on how the release price of nine different tea productions by Yunnan Sourcing have shifted over the years.
