The grinder weighs each dose live during the grinding process and stops automatically as soon as the desired target weight is reached. This reduces the need for manual adjustments and ensures a significantly more convenient workflow.\u003c\/p\u003e\n\u003cp\u003eThis is a real advantage, especially in the world of espresso: Instead of dosing based on time or intuition, you get a clearly defined target amount for every shot. This improves consistency and saves time in your daily routine—especially if you regularly work with the same recipes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant to note:\u003c\/strong\u003e In the prototype analyzed, the GbW function still showed a margin of error of approximately \u003cstrong\u003e±0.5 to 0.6 g\u003c\/strong\u003e. However, Rocket has already announced that it will further optimize the algorithm before the start of mass production.

It’s 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. In practice, this means:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGrind the last dose precisely\u003c\/li\u003e\n\u003cli\u003eClose the hopper\u003c\/li\u003e\n\u003cli\u003eRemove the hopper without tools\u003c\/li\u003e\n\u003cli\u003efill with new beans\u003c\/li\u003e\n\u003cli\u003eContinue with the appropriate recipe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor home baristas who want to switch between \u003cstrong\u003eregular beans and decaf\u003c\/strong\u003e, or between two to three fixed espresso roasts, this is a real advantage. While it’s not a classic single-bin system like that found in specialized single-bin grinders, it’s a very practical and everyday-friendly workflow for discerning households.\u003c\/p\u003e\n\u003ch2\u003eElectronic grind setting instead of traditional 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 1,500 RPM\u003c\/strong\u003e. Practical testing of the prototype also revealed that a long press can even unlock speeds \u003cstrong\u003eof up to 2,000 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 profile and the flavor. Those who experiment with different beans, roasts, and recipe styles gain additional flexibility for fine-tuning.\u003c\/p\u003e\n\u003ch2\u003e63 mm flat burrs in a 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 simple to maintain or replace the burrs.\u003c\/p\u003e\n\u003cp\u003eAnother advantage is the easy access to the interior. For users who value care, cleaning, and long-term maintainability, this is a real plus.\u003c\/p\u003e\n\u003ch2\u003eEase of maintenance—one of the Gravo’s greatest strengths\u003c\/h2\u003e\n\u003cp\u003eIn practical testing, the Rocket Gravo 63 was particularly praised for its \u003cstrong\u003eease of service\u003c\/strong\u003e.

During testing, the ground coffee sometimes came out of the grinder in relatively clumpy chunks. Rocket has already confirmed that a \u003cstrong\u003eredesign of the flapper\u003c\/strong\u003e is planned.\u003c\/p\u003e\n\u003cp\u003eA particularly positive feature: The flapper is very easy to access and should be simple to replace if necessary. This isn’t just user-friendly, but also shows that Rocket is responsive 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 straightforward 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. Although an official dB value isn’t yet available, in practical use the brushless motor operates audibly quietly.\u003c\/p\u003e\n\u003ch2\u003eWi-Fi and Future Potential\u003c\/h2\u003e\n\u003cp\u003eThe Rocket Gravo 63 already features \u003cstrong\u003eWi-Fi hardware\u003c\/strong\u003e. Rocket plans to use this to eventually enable features such as \u003cstrong\u003eGrind-by-Sync\u003c\/strong\u003e—that is, coordinated communication between the grinder and a compatible machine.\u003c\/p\u003e\n\u003cp\u003eThis feature does not appear to be fully rolled out at launch, but it makes it clear that the Gravo is intended as a platform for future Rocket integrations.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrinding discs:\u003c\/strong\u003e 63 mm, flat, blind \/ screwless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor:\u003c\/strong\u003e brushless, 300 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM:\u003c\/strong\u003e 500–1500 RPM standard, up to 2000 RPM with a long press\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrinding capacity:\u003c\/strong\u003e up to 2.5 g\/s at 1500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHopper capacity:\u003c\/strong\u003e 300 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e 2.5\" touchscreen\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosing modes:\u003c\/strong\u003e GbW, GbT, Single Shot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecipe memory:\u003c\/strong\u003e up to 3 recipes per mode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W × D × H):\u003c\/strong\u003e approx. 135–140 × 260 × 410 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWi-Fi:\u003c\/strong\u003e Available; future sync features planned\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRocket Gravo 63 Comparison – Who Should Consider This Grinder?\u003c\/h2\u003e\n\u003cp\u003eMany users are currently comparing the \u003cstrong\u003eRocket Gravo 63\u003c\/strong\u003e with models like the \u003cstrong\u003eEureka Mignon Libra\u003c\/strong\u003e or the \u003cstrong\u003eFiorenzato AllGround Sense\u003c\/strong\u003e.
