Mechanical Hand-Cranked Coffee Machine, Manual Coffee Maker Set with Visual Pressure Gauge & 58mm Brewing Head, Pre-soaking Function for Home, Office and Outdoor Travel Camping Use

Pre-infusion (3-5 bar): Low-pressure pre-infusion fully expands and moistens the coffee grounds, releasing aromatic compounds, ready for extraction. (6-9 bar): Gradually increasing pressure balances the acidity and sweetness of the coffee during extraction. (9 bar) Espresso begins here, also suitable for extraction. (9-12 bar) High-pressure slow extraction stimulates the oils and body compounds in the coffee grounds, extracting a rich essence.
