Black Tea (Assam Fully Oxidized) vs. Matcha (Ceremonial Grade Green Tea)
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.
Ceremonial matcha is stone-ground powdered shade-grown green tea leaves (Camellia sinensis). Per 100g powder, it provides roughly 300 kcal, 30.6g protein, 3,200mg caffeine, 5,000–6,500mg epigallocatechin gallate (EGCG), and 2,000mg L-theanine, whisked into 70–80°C water.
