Black Tea (Assam Fully Oxidized) vs. French Press (Cafetiere Immersion Coffee)
Comparing 2 standards across 11 specifications. 11 key differences identified.
Assam black tea (Camellia sinensis assamica) is 100% fully oxidized tea leaf from northeast India. Steeping 2.5g in 200ml boiling water (95–100°C) for 3–5 minutes yields a robust, malty liquor with ~45mg caffeine per 100ml, theaflavins, and thearubigins.
French Press is full-immersion brewing using coarse grounds steep in 92–96°C water for 4–5 minutes before metal mesh filtration. It produces a heavy-bodied cup with 1.30–1.60% TDS containing natural coffee lipids and cafestol diterpenes.
