ROK EspressoGC

Overview

The ROK EspressoGC is a beautifully engineered manual lever espresso maker from London that combines industrial design aesthetics with genuine espresso capability. The GC (Glass Composite) version features distinctive transparent arms made from a durable glass-reinforced composite material that showcases the internal metal components, giving the machine a striking mechanical-art appearance. The brewing process follows classical lever principles: pour hot water into the metal chamber, insert the portafilter loaded with finely ground coffee, and use both arms to press the lever handles downward, forcing water through the grounds at up to 9 bars of pressure. The dual-arm design provides excellent mechanical advantage, making the press surprisingly easy despite generating significant force. The ROK produces authentic espresso with crema, body, and complexity that competes with entry-level electric machines. The device requires no electricity, has minimal moving parts, and is built to last decades — ROK offers a 10-year guarantee. Pre-infusion is achieved naturally by gently pressing before applying full force. For design-conscious coffee lovers who want a conversation-piece brewer that also produces excellent espresso, the ROK is uniquely compelling.

The ROK EspressoGC comes equipped with pre-infusion for even extraction, pressure profiling for advanced shot manipulation. It features a none boiler system. The manual lever pump delivers 9.0 bars of pressure for optimal extraction.

Priced at $200, the ROK EspressoGC is designed for budget-conscious beginners and casual coffee drinkers. As a manual/portable machine, it offers ultimate control and portability, making great espresso possible anywhere.
