There are two main types of boilers: single boiler and dual boiler. Single boiler machines heat water for both brewing espresso and steaming milk, while dual boiler machines have separate boilers for each function. Dual boiler machines offer greater temperature stability and allow baristas to brew espresso and steam milk simultaneously, leading to faster service. Dual boiler systems are the standard for busy coffee shops.
Group Heads: The group head is where the espresso is extracted. Commercial machines typically have two or three group heads, allowing baristas to brew multiple shots of espresso at the same time. Each group head should have its own independent temperature control to ensure optimal extraction for different coffee blends.
Pump Pressure: Espresso extraction requires a specific amount of pressure, typically around 9 bars (approximately 130 PSI). Commercial espresso machines utilize powerful pumps to generate and maintain this pressure, ensuring a consistent and even extraction. Consistent pressure is a sign of a quality machine.
Temperature Stability: As mentioned earlier, temperature stability is critical for achieving consistent espresso quality. Commercial machines are designed with advanced temperature control systems that minimize temperature fluctuations throughout the brewing process. This often involves using PID (Proportional-Integral-Derivative) controllers to precisely regulate the boiler temperature.
Pre-infusion: Pre-infusion is a technique where the coffee grounds are gently wetted with water before the full pressure is applied. This allows the grounds to expand and degas, resulting in a more even extraction and a richer, more flavorful espresso. Many commercial machines feature pre-infusion capabilities, either manually controlled or automated.
Steam Wand: The steam wand is used to froth milk for lattes, cappuccinos, and other milk-based drinks. Commercial machines typically have powerful steam wands that can quickly and efficiently create microfoam, which is essential for latte art. A powerful, well-designed steam wand is a must for any coffee shop machine.
Automatic vs. Semi-Automatic: Espresso machines fall into two main categories: automatic and semi-automatic. Automatic machines, also known as volumetric machines, automatically stop the espresso extraction after a pre-programmed amount of water has been dispensed. Semi-automatic machines require the barista to manually start and stop the extraction. While semi-automatic machines offer more control, automatic machines are generally preferred in high-volume coffee shops for their consistency and ease of use.
