What You Need to Know
Brewing tea involves heat‑induced extraction of catechins, theaflavins, and thearubigins, with temperature and steeping time controlling oxidation and flavor. The process balances antioxidant release against astringency, producing distinct sensory profiles.
The Science
Primary Reaction
Heat‑induced extraction and oxidation of polyphenols (catechins, theaflavins, thearubigins).
