Master the art of espresso brewing with a commercial espresso machine. These robust machines, designed for high-volume operations, offer unparalleled precision in controlling water temperature and pressure, ensuring each shot is a testament to your craft.
Overview & Background
Commercial espresso machines are the backbone of many coffee shops and cafes. They are engineered to handle the demands of a busy environment, delivering consistent quality and speed. Unlike domestic machines, commercial espresso machines often feature advanced features like PID temperature control, programmable recipes, and multiple portafilter stations, making them indispensable for baristas.
Key Brewing Parameters / Specs
- Water Temperature: Typically set between 195°F (90°C) and 205°F (96°C) to extract the optimal flavor from the coffee beans.
- Pressure: Commercial machines maintain a consistent pressure of around 9 bar (130 psi) to ensure a rich and creamy crema.
- Extraction Time: Aim for a consistent 25-30 seconds to achieve the right balance of flavor and body.
- Dose of Coffee: Generally, 7-9 grams per shot is recommended, though this can vary based on the desired strength.
