Espresso (Standard Double Shot 1:2) vs. Sencha (Japanese Green Tea)
Comparing 2 standards across 13 specifications. 13 key differences identified.
A standard double espresso is prepared by forcing 9 bars of pressurized hot water (90–93.5°C) through 18g of finely ground coffee in 25–30 seconds, yielding 36g of liquid beverage. Per 100ml, it delivers ~212mg caffeine, an 8.5–11.0% TDS, and a persistent crema emulsion.
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.
