Oolong's Stem Holds More Linalool and Geraniol Than Its Leaf
A 2025 tissue-level study of Tieguanyin found the stem holds more linalool, geraniol and other floral compounds than the leaf. A 2022 study found leaf processed with its stem attached finishes lower in linalool and higher in nerolidol than leaf processed alone.
Why one plant makes green, oolong, and black tea
Green, oolong, and black tea are the same leaf from Camellia sinensis. What separates them is processing, above all how much enzymatic oxidation the maker allows before heat arrests it.
Oolong Aroma
More than 300 volatiles have been identified in oolong, and most of them were not in the fresh leaf. What the stress route and the roast each contribute, and why the received account of the locked glycoside pool is contradicted by direct measurement.
Kill-Green
The heat step that arrests enzymatic oxidation in oolong. What denatures the enzymes and why it cannot be undone, the wok and the drum with their real numbers, how a maker judges it done, the two ways it fails, and the later defect that only resembles one.
Oolong Oxidation and Roast
The two axes that define an oolong. What enzymatic oxidation is and how it is arrested by kill-green, why oolong sits partly oxidized between green and black, and how roasting is a separate step applied afterward.
