4 Reasons to Choose a Grind by Weight Coffee Grinder (and Which Ones to Buy)

When it comes to espresso grinders, you can broadly split them into two categories: time-based grinders and weight-based grinders, commonly known as GBW (Grind by Weight).

The latter tend to be more expensive, as they incorporate advanced technology: a built-in scale that weighs the coffee in real time as it’s being ground. But is a GBW grinder really worth the investment? In our opinion, yes and here are four reasons why. 

Faster, smoother workflow 

With a built-in scale, there’s no need to weigh your beans before grinding. The grinder automatically dispenses the exact amount of coffee you’ve set. 

This doesn’t just speed things up—it also improves precision and, most importantly, consistency. Many GBW grinders allow you to save multiple recipes, so even if you switch portafilters, doses, or coffee beans, you can recall your preferred settings. 

No more recalibration 

How often have you had to recalibrate your grinder after changing beans, recipes, or portafilters? It happens all the time and it’s one of the most frustrating parts of dialing in. 

With a GBW grinder, that problem essentially disappears. Thanks to the integrated scale, the grinder automatically tares when you insert the portafilter and delivers the exact dose you’ve set, regardless of variables like coffee type or accessories. 

Less coffee waste 

Fewer recalibrations also mean less waste. 

With time-based grinders, it’s normal to go through several test shots just to match grind time with the desired dose. With GBW, every grind is accurate down to the gram—no trial and error, no wasted coffee, regardless of the setup or beans you’re using. 

An investment that pays off 

We get it—GBW grinders usually come with a higher price tag. But over time, they can actually save you money. 

For one, you can say goodbye to an external scale—there’s no need to weigh beans before grinding. On top of that, you’ll waste far less coffee since you won’t need multiple attempts to dial in your dose. 

And then there’s something people often overlook: time. Making coffee becomes faster and more streamlined, with fewer steps involved. It’s a small change that makes a real difference day after day. 

On our website, you’ll find a wide selection of Grind by Weight grinders. Below are a few models we recommend for home use, with professional-level performance. 

Eureka Mignon Libra e Libra 65 All Purpose 

If you’re looking for a GBW grinder for home use, chances are you’ve already come across the Eureka Mignon Libra line—one of the current benchmarks in this category. 

The Mignon Libra is a great entry point into grind-by-weight grinding. Both the Libra and the Libra 65 are compact grinders equipped with flat burrs, Eureka’s Silent Technology for quieter operation, and a patented stepless micrometric adjustment system for precise control over grind size. 

The Libra 65, however, takes things a step further. It features 65 mm flat burrs instead of the 55 mm found in the standard Libra, resulting in improved speed and consistency. It also uses a blind upper burr, which helps reduce coffee retention. 

Another upgrade is usability: the Libra 65 comes with the King Size Dial, a larger and more intuitive adjustment knob. On the standard Libra, this is available as an optional add-on. 

Both models are available in three finishes—chrome, black, and white—and fit seamlessly into any home coffee setup. 

Note: the Mignon Libra is currently available at 10% off. If you’re thinking about getting into GBW grinding, this could be a great opportunity. 

Mahlkonig E64 WS

No list would be complete without what many consider the king of coffee grinders: Mahlkönig. 

The E64 WS is a next-generation home grinder designed for enthusiasts who want true café-level performance in their own kitchen. It doesn’t just feature Grind by Weight technology, it goes a step further with Grind by Sync (GBS). 

In practice, this means the grinder can actively communicate with compatible espresso machines. Based on extraction data, it automatically adjusts grind size to keep your shot within the ideal range. This level of automation was virtually unheard of in home setups until recently. 

The E64 WS is equipped with 64 mm hardened steel flat burrs and operates at 1950 rpm, delivering fast and consistent grinding. 

With this model, Mahlkönig raises the bar once again, pushing home GBW grinders into a new level of innovation. 

Rocket Espresso Gravo

Gravo marks Rocket Espresso’s entry into the world of Grind By Weight grinders, bringing an approach focused on precision and long-term consistency. 

Thanks to GBW technology, the grinder weighs the coffee directly during grinding, eliminating the need for external scales or manual adjustments. This results in perfectly consistent doses and extremely accurate control over extraction, shot after shot. 

The display is simple and intuitive, allowing users to save up to three recipes. Every parameter can be customized: from dose weight to motor speed (RPM), as well as the burr distance, which is electronically controlled to ensure fast and reliable adjustments. 

Gravo features 63 mm flat burrs with a screwless design, a solution developed to reduce retention and preserve the freshness of the ground coffee. 

From an aesthetic standpoint, the grinder stands out with its solid, modern look, perfectly aligned with Rocket’s design identity. It is not just a technical tool, but a true design element capable of enhancing any coffee station. 

Among its most distinctive details is the knurled metal band around the hopper, a nod to the world of high-end automotive and fine jewelry, conveying a strong sense of precision, quality, and craftsmanship. 

Fiorenzato AllGround Sense

Italian design and engineering take center stage once again with the Fiorenzato AllGround Sense, a grinder built for those who want versatility without compromising on precision. 

One of its standout features is flexibility: whether you’re grinding for espresso, moka, or filter, you can easily switch between brewing methods by simply turning the adjustment dial and selecting the appropriate grind size. It’s a practical solution, especially for those who like to experiment with different brewing styles at home. 

The intuitive touchscreen display makes the process even easier, allowing you to select the exact grams you want to grind. This makes Grind by Weight technology truly accessible for everyday use, reducing both errors and waste. 

On the technical side, the AllGround Sense features 64 mm flat burrs with Dark-T coating, designed for enhanced durability and a lifespan of up to 3,000 kg of coffee ground. A detail that makes it particularly appealing in terms of long-term reliability. 

All of this is wrapped in a solid build and a clean, elegant design that fits naturally into any kitchen. It’s a grinder that successfully combines aesthetics and functionality, with a very practical approach. 

Faster workflow, no more recalibration, and less wasted coffee: these are the key reasons to keep in mind if you’re considering switching to a Grind by Weight grinder.
