What You Need to Know
The infusion relies on the hydrolysis of anthocyanin glycosides into aglycones, which are more soluble in hot water and give the drink its characteristic purple hue. Sugar dissolves at 100 °C, increasing viscosity and sweetness, while phenolic compounds from the corn husks can impart bitterness if over‑steeped.
