1. Lever-operated mechanism
The lever-operated mechanism is a defining characteristic of classic La San Marco espresso machines, distinguishing them from pump-driven models. It places the control of the brewing process directly into the hands of the barista, offering a unique level of control over the extraction parameters.
-
Pre-infusion
Lowering the lever initiates pre-infusion, gently saturating the coffee grounds with water. This crucial step prepares the coffee for extraction and contributes to a more balanced, flavorful espresso. The duration and pressure of pre-infusion can be adjusted by the barista based on the coffee being used.
-
Manual Pressure Profiling
Unlike automated machines, a lever group allows the barista to manually control the pressure applied to the coffee puck throughout the extraction process. This control enables fine-tuning the extraction curve, maximizing flavor development and avoiding over-extraction or under-extraction. This is particularly valuable for experimenting with different roasts and grind sizes.
-
Direct Feedback and Tactile Engagement
The direct physical connection to the brewing process through the lever provides immediate feedback on the resistance of the coffee puck and the flow rate of the espresso. This tactile engagement enhances the barista’s understanding of the extraction dynamics and contributes to a more nuanced and controlled brewing experience.

Pre-infusion Control
The initial lever position regulates the pre-infusion phase, dictating the duration and pressure applied to the saturated coffee grounds. This control allows baristas to tailor the pre-infusion to specific coffee beans, optimizing the extraction for different roast levels and grind sizes. A longer, gentler pre-infusion might suit a lighter roast, while a shorter, more forceful one might benefit a darker roast. This nuanced control over pre-infusion directly impacts the espresso’s overall balance and complexity.
-
Pressure Profiling During Extraction
Unlike automated machines with fixed pressure profiles, La San Marco machines enable baristas to adjust the pressure throughout the extraction process. This dynamic control allows for manipulation of the extraction curve, influencing the balance of sweetness, acidity, and bitterness in the final cup. A skilled barista can fine-tune the pressure to highlight specific flavor notes, compensating for variations in coffee beans or ambient conditions.
-
Tactile Feedback and Adjustment
The lever’s physical resistance provides direct feedback on the pressure being applied to the coffee puck. This tactile feedback loop allows for real-time adjustments, ensuring consistent results. Baristas can feel changes in resistance as the coffee extracts, allowing them to fine-tune the pressure curve and achieve optimal extraction. This intimate connection with the brewing process elevates espresso preparation to an art form.
-
Consistency and Repeatability
While manual control might appear challenging, it facilitates consistency once mastered. A skilled barista can repeat specific pressure profiles, ensuring consistent results across multiple shots. This precision is particularly important in professional settings where consistent quality is paramount. The ability to replicate successful extractions guarantees a predictable and enjoyable experience for the consumer.
