Yellow Tea

by Lydia Kung

This once relatively obscure category was associated with Anhui and Hunan, specifically with two rare and pricey teas from those provinces. Historically, the color yellow was reserved for the imperial court (viz. emperor’s robes, etc.) and so even today, the color carries not a little cachet in gifting and in the promotion and marketing of this group of teas.

Because Yellow tea processing involves more steps than Green tea processing, and because of the labor intensive steps, the raw material that goes into Yellow teas is of high quality: buds and tender budsets. (And alas, also explains the price level.) After indoor withering and de-enzyming over dry heat, the still warm leaves are covered with cloth or paper. This covering period can be for several hours or up to a day. (In some cases, for certain teas, slight oxidation is intentional.)

The temperature surrounding the leaves, of course, varies as the leaves rest before the final drying. Due to the covering, there is also less evaporation or dissipation of the components in the leaves that yield aroma. The moisture and heat act on the polyphenols and chlorophyll in the leaves, and as the chlorophyll breaks down, the leaves take on a yellowish hue (just as with green leafy vegetables if kept too long).

This added step of covering small piles of leaves allows the warm temperature and moisture to act upon the leaves, eliciting a more complex flavor than would be the case for standard Green tea processing. Rolling and drying follow.
