A portable, human-powered device extracts espresso by leveraging manual force applied to a lever or piston. This action pressurizes hot water through finely-ground coffee, producing a rich, concentrated beverage. Flair and ROK are examples of prominent brands in this category.
These devices offer a unique level of control over the brewing process, allowing the user to fine-tune parameters like pressure and flow rate, resulting in a highly customizable espresso experience. Furthermore, their portability and independence from electricity make them appealing for travel, camping, or off-grid use. Historically, lever-operated espresso machines predate electric pumps, representing an early form of espresso preparation that emphasizes the user’s skill and technique.
