What You Need to Know
Water heated in lower chamber creates steam pressure (1.5 bar max), forcing water through ground coffee in a filter basket. Unlike espresso machines, no pump generates pressure - only steam expansion. Yields 8-12% TDS (total dissolved solids).
Produces concentrated coffee with crema-like foam, stronger than drip but less intense than true espresso. Ideal for milk-based drinks or solo consumption.
