Coffee grinding is an art form; every process step counts when striving for that perfect brew. Among the hurdles that coffee aficionados often face is static electricity, a common nuisance that can compromise the quality of the grind. Enter the Acaia Ion Beam, a groundbreaking device designed to neutralize static charge in ground coffee. This pioneering innovation is set to redefine the coffee grinding experience, promising smoother, cleaner, and more efficient brewing.

Features of the Acaia Ion Beam

The Acaia Ion Beam is a revolution in coffee equipment technology. A meticulously designed gadget, its purpose is to neutralize the static charge often experienced when grinding coffee beans. The fixed charge is a common issue for baristas and coffee lovers alike, causing coffee grounds to cling to the grinder and the receptacle, thereby making a mess and affecting the overall quality of the grind. The Ion Beam tackles this issue head-on, ensuring the grind is smooth and the process cleaner and more efficient. Its industrial-grade ion generator, portability, and compatibility with different grinders have set it apart. This innovation has captured the attention of the coffee industry, marking an exciting moment in coffee grinding technology.

Negative and Positive Ion Generation

One of the defining features of the Acaia Ion Beam is its capacity to generate negative and positive ions. This technology targets the static buildup that occurs during the grinding process. Negative ions are generated from the front end of the Ion Beam, and positive ions from the back end. This setup lets it neutralize either positive or negative static charges that build up in coffee grounds during grinding. Several factors such as the coffee’s roast level, the grinder style, and atmospheric conditions, can affect static electricity buildup. With its dual ion generation, the Ion Beam offers an effective solution to static-induced issues, leading to a cleaner and smoother coffee grinding experience.

Material and Mounting

The Ion Beam is thoughtfully constructed using durable materials such as aluminum and polycarbonate. This sturdy construction ensures its longevity even with regular use. The design of the Ion Beam allows it to mount directly onto Acaia’s Orbit coffee grinder, effectively directing ions to the outbound path of ground coffee. This integration makes it highly effective in neutralizing static electricity. Additionally, the Ion Beam's mounting feature enhances its portability, enabling users to easily set it up with different grinders and adjust it to an ideal position for best performance.

How it Works

According to Acaia Co-Founder Rex Tseng:

"The majority of coffee grounds are positively charged. Therefore, the front of the Ion Beam generates negative ions to neutralize the charged coffee particles while coffee grounds are exiting the chute.”

This means that the Ion Beam is designed to generate ions based on the specific needs of the coffee grounds, depending on whether they are positively or negatively charged. In cases where coffee grounds are negatively charged, the Ion Beam is turned around to let the back end emit positive ions. This flexibility and adaptability to varying grinding scenarios set the Acaia Ion Beam apart from other coffee-grinding accessories.

Acaia's Battle with Static Electricity

Static electricity has always been a considerable challenge for grinder manufacturers. Due to the friction between roasted coffee beans, burrs, and other grinder components, static is naturally generated. This static behaves like a magnet, causing lightweight coffee particles to either cling or repel wildly as they exit the grinder, making a mess on the counter and causing clumping in the receptacle. Acaia, with its Ion Beam, is pioneering a solution to this long-standing problem. The Ion Beam is designed to neutralize the static charge, resulting in a more tidy, clump-free bed of coffee. With this groundbreaking solution, Acaia is leading the charge against static electricity in coffee grinding, promising an improved experience for all coffee enthusiasts.


The Acaia Ion Beam combines impressive specifications that make it a standout addition to the world of coffee grinding. Beginning with its lightweight design, the Ion Beam weighs a mere 188.5 grams, ensuring its portability and ease of use. This is coupled with compact dimensions - a diameter of 42mm and a length of 170mm- contributing to its sleek and user-friendly design. The Ion Beam is crafted from robust and high-quality materials, predominantly aluminum and polycarbonate, ensuring its durability and longevity.

Powering the Ion Beam is a rechargeable lithium-ion battery with a capacity of 3.7V and 780mAh. This potent power source provides an impressive battery life of up to 8 hours, allowing users to enjoy numerous grinding sessions without worrying about frequent recharging. The Ion Beam has an attachment thread of 1/4"-20 for easy mounting onto the Orbit coffee grinder or a tripod stand for other heroes.

Regarding connectivity, the Ion Beam is up-to-date with the latest Bluetooth 5.0, facilitating seamless connectivity for any necessary updates or features. Lastly, Acaia ensures peace of mind for its customers by offering a one-year warranty for the Ion Beam, underlining their confidence in its quality and durability. With these specifications, the Acaia Ion Beam is well-equipped to provide a remarkable, hassle-free coffee grinding experience.

Other Acaia Innovations

Acaia is not just about Ion Beams. The company is also set to unveil the Orion Nano, a smaller version of its popular whole-bean dosing machine. This gadget is designed for precision, ease of use, and space-saving, further exemplifying Acaia's commitment to enhancing your coffee experience. With two-thirds the footprint of the original Orion Bean Doser, the Orion Nano is an exciting addition to Acaia's innovative product lineup.

Ross Droplet Technique (RDT) vs. Ion Beam

While the Ross Droplet Technique (RDT) has favored reducing static electricity in coffee grinding, the Acaia Ion Beam introduces a new, efficient approach. Unlike RDT, which involves adding a tiny bit of water to whole beans before grinding, the Ion Beam uses ion generation to tackle static electricity directly. While both methods have their merits, the Ion Beam offers a more practical, mess-free, and consistent solution to the age-old static problem in coffee grinding.


The Acaia Ion Beam is more than just a gadget—it’s a game-changer in the coffee industry. With its robust ion generation technology, it tackles the issue of static electricity head-on, ensuring that your coffee grind is not only smoother but also mess-free. Its unique blend of technical prowess, portability, and compatibility with different grinders makes it a must-have accessory for every coffee lover. The Ion Beam embodies Acaia's commitment to innovation and quality, from impressive features to high-grade construction. Whether you're a seasoned barista or a home brewing enthusiast, the Acaia Ion Beam promises to enhance your coffee grinding experience.
