A Decades-Long Pursuit of Simplicity The Strietman CT2 represents a rare intersection in consumer electronics: a product that refuses to participate in the race for digital complexity. Created by Wouter Strietman, this manual lever machine began as a university project over a decade ago. It has since evolved into a refined, heirloom-quality device. Unlike modern machines cluttered with vibration pumps and miles of internal wiring, the Strietman CT2 relies on high-grade brass, copper, and stainless steel. It is a direct lever machine, meaning the user provides the pressure, creating a tactile connection between the barista and the extraction process that most automated systems simply cannot replicate. Technical Mastery and Thermal Stability While the design feels vintage, the performance is cutting-edge. The machine features a saturated group head where the open boiler and group are a single unit, ensuring remarkable thermal stability. It utilizes a PID controller with an adjustable knob ranging from 80°C to 96°C. This range allows for extreme precision, whether you are pulling a delicate decaf at lower temperatures or a light roast that requires high heat. Within 11 to 15 minutes, the heavy metal components reach a stable state, allowing for consistent shots that rarely deviate more than a few degrees throughout the pull. This reliability eliminates the frustrating "temperature surfing" required by older lever designs like the La Pavoni. The Case for the 49mm Basket A central point of contention in the coffee world is basket diameter. While 58mm is the industry standard, the Strietman CT2 employs a 49mm basket. The performance advantage here lies in the aspect ratio. A smaller diameter results in a deeper coffee puck for the same dose. This depth creates more resistance and forgiveness during the shot, yielding a syrupy texture and high acidity without the bitterness often found in shallower pucks. You can achieve a perfect 1:2.5 ratio with a 14g dose, providing a concentrated, flavorful experience without the excessive caffeine load of the massive doses required to get similar depth on 58mm equipment. Practical Trade-offs and Final Verdict Luxury often comes with friction. The Strietman CT2 has a high price tag—roughly €2,000—and a tiny clearance between the drip tray and the portafilter. Standard scales like the Acaia Lunar barely fit, and users might find themselves limited to smaller glassware. Furthermore, there is no built-in pressure gauge, requiring users to pull by feel unless they install a third-party Smart Espresso Profiler kit. However, for the espresso purist, these are minor hurdles. The machine is essentially a lifetime purchase, built with the simplicity of a V60 but the engineering of a high-end vintage vehicle. It is a functional piece of art that rewards the user with some of the most consistent, vibrant espresso available on the market today.
