Manufactured by Rocket Espresso, an Italian company known for producing high-quality espresso machines, the R58 is a true workhorse designed to deliver exceptional espresso shots and milk frothing capabilities. In this comprehensive review, we will delve into the various aspects of the Rocket R58, exploring its design, features, performance, usability, maintenance, and overall value. Let’s take a closer look at this impressive espresso machine.
Section 1: Design and Build Quality
The Rocket R58 exudes a classic and elegant design, characteristic of Italian espresso machines. Its stainless steel body, polished to perfection, not only looks stunning but also ensures durability and longevity. The machine is available in two color options: polished stainless steel and matte black. The attention to detail in the design is evident in the stylish accents, such as the Rocket Espresso logo and the lever-operated steam and hot water wands.
The R58 measures approximately 16.25 inches in height, 11 inches in width, and 17 inches in depth, making it relatively compact compared to other dual boiler machines. It’s worth noting that the machine carries some weight due to its sturdy construction, weighing in at around 65 pounds (29.5 kg).
The build quality of the Rocket R58 is exceptional, with high-grade materials used throughout the machine. The robust stainless steel construction ensures stability and minimizes vibrations during use, contributing to a more consistent extraction process.
Section 2: Features and Specifications
Dual Boiler System: One of the standout features of the Rocket R58 is its dual boiler system. This design allows the machine to simultaneously brew espresso and froth milk without any noticeable temperature fluctuations. The stainless steel boilers, with a capacity of 0.58 liters for the brew boiler and 1.7 liters for the steam boiler, provide ample capacity for producing multiple shots and steaming milk for larger milk-based drinks.
PID Temperature Control: The R58 is equipped with a PID (Proportional-Integral-Derivative) controller, which offers precise temperature control for both boilers. This feature allows the user to adjust and maintain the brew and steam temperatures to achieve the optimal extraction and milk frothing results. The PID display is conveniently located on the machine’s front panel for easy access.
Rotary Pump: The Rocket R58 is equipped with a quiet and efficient rotary pump, which provides consistent water pressure and enhances the overall stability of the extraction process. The rotary pump is favored by many coffee enthusiasts for its ability to deliver smooth and reliable water flow, resulting in more consistent shots.
Commercial-Grade Portafilter and Grouphead: The R58 boasts a commercial-grade, 58mm portafilter and grouphead, which are constructed from heavy-duty chrome-plated brass. This professional-grade setup ensures excellent heat retention and distribution, leading to more stable temperature during the brewing process and consistent extractions.
Pressure Gauges: Two pressure gauges are integrated into the front panel of the R58—one for the brew pressure and the other for the steam pressure. These gauges provide real-time feedback on the pressure levels, allowing the user to make necessary adjustments for optimal brewing and steaming.
Hot Water Dispenser: Apart from its espresso brewing capabilities, the Rocket R58 features a dedicated hot water dispenser, allowing you to dispense hot water for making Americanos, teas, or other hot beverages with ease.
Section 3: Performance and Espresso Quality
The Rocket R58 is designed to excel in delivering exceptional espresso shots with rich crema, full-bodied flavor, and well-defined aromas. The dual boiler system, coupled with the PID temperature control, ensures precise control over the brewing process, allowing for consistent extraction temperatures. This level of control is crucial for achieving optimal flavor extraction from the coffee grounds.
The commercial-grade portafilter and grouphead contribute significantly to the R58’s performance. The chrome-plated brass construction aids in temperature stability and retention, helping to maintain consistent heat throughout the brewing process. The result is a more balanced and nuanced flavor profile in the espresso shot.
Additionally, the machine’s pre-infusion feature allows the coffee grounds to be saturated with hot water briefly before the full extraction begins. This step helps to ensure an even and thorough extraction, further enhancing the overall flavor complexity of the espresso.
Overall, the espresso quality produced by the Rocket R58 is impressive and comparable to that of professional-grade espresso machines found in specialty coffee shops.
Section 4: Milk Frothing and Steaming
The Rocket R58’s dual boiler system and powerful steam wand make it a top performer when it comes to milk frothing and steaming. The steam boiler’s ample capacity provides a consistent and continuous flow of steam, allowing for effortless milk frothing for cappuccinos, lattes, and other milk-based beverages.
The commercial-grade steam wand, operated by a lever, offers excellent control over the steam flow and pressure. It enables users to texture milk to their desired level of creaminess, producing silky microfoam for latte art or thick froth for cappuccinos.
The machine’s ability to steam milk while brewing espresso simultaneously is a significant advantage, especially in a commercial setting or when making multiple drinks in quick succession. The dual boiler design ensures that there is no downtime between brewing and steaming, making it a time-saving feature for busy coffee shops or home baristas entertaining guests.
Section 5: User-Friendliness and Operation
Despite its professional-grade features and capabilities, the Rocket R58 is surprisingly user-friendly and straightforward to operate. The intuitive control layout, along with clear pressure gauge readings, makes it easy for users of all experience levels to use the machine effectively.
The PID temperature controller is easy to adjust, allowing users to set and maintain precise brewing and steaming temperatures according to their preferences. The lever-operated steam and hot water wands offer excellent control, enabling users to fine-tune the frothing and dispensing process.
The Rocket R58’s dual boiler system also contributes to its user-friendliness. Being able to brew espresso and steam milk simultaneously is a convenience that many users appreciate, as it saves time and effort during the coffee-making process.
Section 6: Maintenance and Cleaning
Proper maintenance and regular cleaning are essential for keeping any espresso machine in top condition, and the Rocket R58 is no exception. Fortunately, the machine’s design simplifies the maintenance process.
The removable drip tray and water reservoir make cleaning and refilling hassle-free. The stainless steel body is easy to wipe down and maintain its shine. The stainless steel boilers require descaling periodically to remove mineral deposits and ensure optimal performance.
Additionally, the Rocket R58’s E61 grouphead design allows for easy backflushing, a process that helps clean the brew group and remove any built-up coffee oils. The process is straightforward and can be done regularly to keep the grouphead clean and functioning optimally.
Section 7: Value for Money
The Rocket R58 is considered a high-end espresso machine, and its price reflects the level of craftsmanship, performance, and features it offers. While it may not be the most budget-friendly option for those new to espresso machines, it is a solid investment for serious coffee enthusiasts and professionals seeking a top-tier espresso experience.
The machine’s durable construction, exceptional performance, and user-friendly design justify its higher price point. For those who are passionate about coffee and value precision and consistency in their espresso shots, the Rocket R58 delivers a level of quality that is often found in commercial-grade espresso machines.
