Episode notes
Tea's Origins Shape Modern Taste
- Tea began as chewed leaves and evolved into a drink after Lu Yu's 8th-century Tea Classic promoting powdered leaf infusions.
- Lu Yu's emphasis on picking time and sunlight still guides modern tea quality judgments.
Teabags Prioritize Strength Over Nuance
- The CTC machine and teabag production in the 1900s increased surface area of tea particles, producing faster, stronger brews.
- That speed sacrificed subtle flavor compounds present in larger loose leaves.
Preheat Vessels And Use Boiling Water
- Preheat your mug or teapot and brew black tea in boiling water (~212°F) to avoid heat loss and weak extraction.
- Use a tea cozy or warm vessel to keep temperature steady during brewing.
