Ristretto (Restricted Espresso Shot 1:1) vs. Yerba Mate (Traditional South American Ilex)
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.
Yerba Mate is an infusion of dried leaves and stems of Ilex paraguariensis. Traditionally prepared in a calabash gourd with a metal bombilla at 70–80°C, it provides ~78mg caffeine per cup, theobromine, theophylline, and chlorogenic acid antioxidants.
