Nespresso Essenza Plus: Advanced 19-Bar Capsule System with 1.0L Reservoir

From an engineering perspective, the Essenza Plus utilizes a vibratory pump capable of 19 bars of static pressure, necessary to overcome the resistance of the hermetically sealed capsule. The internal fluid dynamics are managed by a precise flow meter that regulates output volumes for the Americano and Americano XL presets, ensuring the water-to-coffee ratio remains consistent within a +/- 5% margin. Thermal management is handled by a compact thermoblock heat exchanger; while it lacks PID control found in prosumer machines, it maintains an extraction temperature between 83°C and 86°C, which is the industry standard for capsule-based systems. The 1.0L tank is a significant upgrade over the 0.6L found in the Essenza Mini, providing a better volume-to-descaling ratio. The inclusion of a dedicated hot water pipe is a strategic mechanical addition, bypassing the brewing chamber to prevent coffee residue from contaminating plain hot water. The plastic build, while primarily for weight reduction, is designed with structural ribs to mitigate vibration noise common in 19-bar vibratory pump systems.
