Ristretto (Restricted Espresso Shot 1:1) vs. Sencha (Japanese Green Tea)
Comparing 2 standards across 13 specifications. 13 key differences identified.
Ristretto is a restricted extraction espresso stopping at a 1:1 to 1:1.5 ratio (18g dry dose yielding 18–22g liquid) in 18–22 seconds, extracting sweet, viscous, low-bitterness solubles with an intense 11–14% TDS.
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.
