Londinium

The Allure of the Spring Lever Londinium carved a niche in the enthusiast market with the R24, a machine that combined traditional lever mechanics with modern pump-driven pre-infusion. The Londinium Vectis arrives as a stripped-back, compact alternative designed for purists. It eliminates the pump entirely, relying on a single boiler and a spring-actuated lever to drive extraction. While the initial hype suggested a $1,000 price point, the reality at launch landed closer to $2,000. For that investment, users receive a machine that prioritizes tactile feedback and a small footprint, though it demands significant trade-offs in versatility. Technical Performance and Pressure Realities One of the most critical aspects of any spring lever is the force it exerts. While the Vectis purportedly houses an 8-bar spring, real-world testing tells a different story. Using a Scace device and customized pressure gauges, the peak pressure rarely exceeds 6 bar, often settling closer to 5.5 bar during the bulk of the extraction. This lower pressure profile limits the machine's ability to handle certain modern espresso styles that require higher force to penetrate dense, finely ground pucks. Pre-infusion is equally restricted. Without a pump, the machine relies on steam pressure—typically around 1.2 bar—to saturate the coffee. This low-pressure "steam pre-infusion" means the puck won't reach full saturation as quickly or deeply as a pump-driven system, effectively capping the maximum yield. If you are chasing high-ratio shots (1:3 or 1:4), you will find the Vectis struggling to deliver more than 40-42 grams without resorting to manual "Fellini" pulls. Build Quality and Quality Control Concerns Early adopters reported several quality control issues that dampen the premium feel of a $2,000 device. These range from cosmetic frustrations, such as poor welding on the drip tray and charred edges near internal joints, to functional failures like leaking boilers. A recurring issue involved the pressure stat (P-stat), which regulates boiler temperature. Some units experienced pressure spikes as high as 1.5 bar, well beyond the safe operating range. While Londinium founder Reese has been proactive in sending replacement parts and redesigning the P-stat mounting to include a "J-hook" for better thermal isolation, these are hurdles a consumer shouldn't face at this price point. Ergonomics and Everyday Use The user experience is a mix of brilliance and annoyance. The lever action features a unique spring-loaded "bounce" at the bottom of the stroke, preventing the jarring metal-on-metal clank found on most competitors. However, the proprietary 58mm group head is frustratingly picky. It lacks compatibility with many aftermarket portafilters and high-end baskets. The mirror finish is a fingerprint magnet, and the water fill system—requiring a specific funnel to depress a valve—is over-engineered compared to a simple screw cap. For those seeking a "one-and-done" shot with traditional ratios, the Vectis offers a rewarding, quiet workflow, but its limitations make it difficult to recommend over more versatile competitors.
