What You Need to Know
Utilizes the high thermal conductivity of water ice (0.58 W/m·K) to achieve rapid cooling rates exceeding 50°C/min. The melting ice simultaneously dilutes the brew to proper strength while arresting thermal degradation pathways.
Creates a brighter, more aromatic iced coffee compared to cold brew or slow-chilled methods. The rapid temperature drop preserves delicate fruity and floral notes that would otherwise be lost through gradual cooling.
