Cold Brew Coffee (Slow Cold Immersion) vs. Yerba Mate (Traditional South American Ilex)
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.
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.
