It is an increasingly rare and expensive variety of tea.[3]: 58 The process for making yellow tea is similar to that of green but with an added step of encasing[further explanation needed], or sweltering,[a] giving the leaves a slightly yellow coloring during the drying process.[3]: 32 Yellow tea is often placed in the same category with green tea due to its light oxidation. One of the primary aims of making yellow tea is to remove the characteristic grassy smell of green tea.
Pingyang Huangtang (平陽黃湯): from Zhejiang Province, China. Could be called one of the Wenzhou Huangtang (溫州黃湯); the latter term is literally translated as Yellow BrothorYellow Soup.
In Korean tea terminology wherein domestic tea is categorized mainly as either green tea (nokcha; 녹차) or fermented tea (balhyocha; 발효차) – "fermented" practically meaning "oxidized" with this term[6] – "yellow tea" (hwangcha) is used to denote lightly oxidized balhyocha without implications of processing methods or a result that would qualify the tea as "yellow tea" in the Chinese definition.[6] Unlike Chinese huángchá, Korean hwangcha is made similarly to oolong tea or lightly oxidized black tea, depending on who makes it – the key feature is a noticeable but otherwise relatively low level of oxidation which leaves the resulting tea liquor yellow in color.[citation needed]
^Unique to yellow teas, warm and damp tea leaves from after kill-green are allowed to be lightly heated in a closed container, which causes the previously green leaves to turn yellow. The resulting leaves produce a beverage that has a distinctive yellowish-green hue due to transformations of the leaf chlorophyll.[4] Through being sweltered for 6–8 hours at close to human body temperatures, the amino acids and polyphenols in the processed tea leaves undergo chemical changes to give this tea its distinct briskness and mellow taste.[5]
