Tie Guan Yin is a prized semi-oxidized oolong tea (30–40% oxidation) from Anxi, China. Steeping 5g in 150ml water at 88–92°C in a Gaiwan for 45 seconds produces an orchid floral fragrance, rich theasinensins, and ~25mg caffeine per 100ml over 6+ infusions.
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.
