The grinder weighs each dose live during the grinding process and stops automatically as soon as the desired target weight is reached. This reduces manual adjustments and ensures a significantly more convenient workflow.\u003c\/p\u003e\n\u003cp\u003eThis is a real advantage, especially in the espresso sector: instead of dosing based on time or feel, you get a clearly defined target amount for every shot.

It is therefore suitable for both users seeking maximum consistency and those who want to switch between different coffees and recipes.\u003c\/p\u003e\n\u003ch2\u003eEasy bean change – ideal for decaf and multiple coffees\u003c\/h2\u003e\n\u003cp\u003eOne of the most exciting practical features of the Rocket Gravo 63 is the \u003cstrong\u003e5-part insert system\u003c\/strong\u003e in the bean hopper. Rocket has developed a well-thought-out concept here that allows for more flexible bean changes than many classic hopper grinders.\u003c\/p\u003e\n\u003cp\u003eThe inserts are labeled \u003cstrong\u003eA, B, C, D, and E\u003c\/strong\u003e, and each limits the remaining bean volume in the feed chute. The smallest insert holds approximately \u003cstrong\u003e15 g of remaining beans\u003c\/strong\u003e.

While it’s not a classic single-dose system like that found in specialized single-dose grinders, it’s a very practical and everyday-friendly workflow for discerning households.\u003c\/p\u003e\n\u003ch2\u003eElectronic grind setting instead of classic mechanics\u003c\/h2\u003e\n\u003cp\u003eA key distinguishing feature from the previous generation of Rocket grinders is the \u003cstrong\u003eelectronic grind setting\u003c\/strong\u003e. The grind setting is adjusted digitally via the touchscreen and can be linked directly to recipes.\u003c\/p\u003e\n\u003cp\u003eThis offers clear advantages in everyday use:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eprecise reproducibility\u003c\/li\u003e\n\u003cli\u003eclean operation with saved recipes\u003c\/li\u003e\n\u003cli\u003econvenient switching between different coffees\u003c\/li\u003e\n\u003cli\u003eno cumbersome menu navigation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eImportant to note: Based on current knowledge, the displayed values are \u003cstrong\u003enot actual micrometer measurements\u003c\/strong\u003e but relative scale values. For the user, this is less critical in everyday use than for technical classification—what matters most is that settings can be saved and recalled consistently.\u003c\/p\u003e\n\u003ch2\u003eVariable speed – RPM control up to 2000 rpm\u003c\/h2\u003e\n\u003cp\u003eThe Rocket Gravo 63 typically offers an adjustable speed range from \u003cstrong\u003e500 to 1500 RPM\u003c\/strong\u003e. Practical testing of the prototype also revealed that a long press can unlock speeds of \u003cstrong\u003eup to 2000 RPM\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThis feature is particularly interesting for home baristas who like to experiment. The speed influences both the extraction behavior and the flavor. Those who try out different beans, roasts, and recipe styles gain additional leeway for fine-tuning.\u003c\/p\u003e\n\u003ch2\u003e63 mm flat burrs in blind \/ screwless design\u003c\/h2\u003e\n\u003cp\u003eThe Rocket Gravo uses \u003cstrong\u003e63 mm flat burrs\u003c\/strong\u003e in \u003cstrong\u003ea blind burr design\u003c\/strong\u003e. The upper unit is designed for easy maintenance and is accessible with just a few screws. This makes it relatively easy to maintain or replace the burrs.\u003c\/p\u003e\n\u003cp\u003eAnother advantage is the easy access to the interior.

During testing, the ground coffee sometimes came out of the grinder relatively clumpy. Rocket has already confirmed that a \u003cstrong\u003eredesign of the flapper\u003c\/strong\u003e is planned.\u003c\/p\u003e\n\u003cp\u003eParticularly positive: The flapper is very easy to access and should be simple to replace if needed. This isn’t just service-friendly, but also shows that Rocket responds to real-world feedback.\u003c\/p\u003e\n\u003ch2\u003eQuiet operation and intuitive controls\u003c\/h2\u003e\n\u003cp\u003eIn the test, the Gravo was also described as pleasantly unpretentious to operate. Instead of nested menus, the grinder operates largely directly from the home screen. Settings for dose, RPM, and grind size are quickly accessible and feel very intuitive in everyday use.\u003c\/p\u003e\n\u003cp\u003eThe noise level was also mentioned positively. While an official dB value is not yet available, in practical use the brushless motor operates audibly quietly.\u003c\/p\u003e\n\u003ch2\u003eWiFi and Future Potential\u003c\/h2\u003e\n\u003cp\u003eThe Rocket Gravo 63 already features \u003cstrong\u003eWiFi hardware\u003c\/strong\u003e.
