Cold Brew Coffee (Slow Cold Immersion) vs. Sencha (Japanese Green Tea)
Comparing 2 standards across 12 specifications. 12 key differences identified.
Cold brew coffee is prepared by steeping coarse coffee grounds in room temperature or chilled water (4–20°C) for 16–24 hours. Per 100ml concentrate, it delivers 180–220mg caffeine with 66% lower titratable acidity than hot brews.
Sencha is unshaded, steamed green tea leaf (Camellia sinensis). Steeping 3g in 150ml water at 70–75°C for 60 seconds delivers a refreshing, grassy liquor with ~30mg caffeine per 100ml and rich EGCG catechins.
