TUNI G2 Electric Coffee Grinder Launches in North America with Near-Zero Retention

TUNI, the Rancho Cucamonga, California-based coffee gear brand, launched its G2 Electric Coffee Grinder in North America on March 17, 2026, pricing it at $149 and positioning it as a precision-first option for home baristas who want repeatable results without the counter mess.

The G2's headlining claim is near-zero retention, a spec that matters deeply to anyone who has watched a gram or two of yesterday's Ethiopian natural ghost its way into today's shot. The grinder pairs that claim with 40mm conical burrs and a 70-step grind adjustment spanning ultra-fine espresso all the way out to coarse French press territory. At 200 watts and 4.75 pounds, it sits in a compact footprint measuring 9.1 by 5.4 by 16.1 inches and holds 8.8 ounces (250 grams) of beans in the hopper, with a dosing cup rated for 2.6 ounces (75 grams) of ground coffee.

To address static clinging, one of the more quietly frustrating realities of home grinding, TUNI incorporated what it calls an advanced anti-static design. The product copy promises the technology "dramatically reduces clingy coffee grounds, minimizing mess on your counter and ensuring cleaner, more efficient dosing every time." The included accessories reinforce that workflow focus: a portafilter holder, dosing container, dosing ring, and soft brush all come in the box. The portafilter holder is spec'd for 54mm to 58mm, though the product description elsewhere lists compatibility down to 51mm, a discrepancy TUNI has not publicly clarified.

The G2 ships in three colorways: Silver, Ivory, and Noir. The stainless steel chassis is built around what TUNI describes as a minimalist profile that "hides powerful, professional-grade engineering," a design philosophy the brand's spokesperson elaborated on in the launch announcement.

"At TUNI, we believe that the beauty of coffee should begin long before the first sip. It should begin with the tactile elegance and visual calm of the equipment you use," said Kevin at TUNI. "This new grinder is the physical embodiment of our design DNA, a perfect marriage of professional performance and sophisticated, minimalist aesthetics. Every curve, every material choice, and every interface detail is designed to reflect our philosophy: Focus only on the essence of coffee."

TUNI is explicitly marketing the G2 as a companion to its E2 58mm Espresso Machines, arguing that the 58mm group head provides "the thermal stability and pressure control necessary to fully utilize the G2's precision grind." It's a tidy ecosystem pitch: buy the grinder, buy the machine, and the two are engineered to complement each other on the same kitchen counter.

Founded in 2001, TUNI describes itself as a brand built on "honest materials, smart engineering, and elegant tools." The G2 is now available through Amazon and the company's own website at the $149 launch price, with shipping calculated at checkout and flexible returns offered through the direct channel. The product page launched with zero customer reviews, meaning the near-zero retention claim, like the grinder itself, is still waiting to be tested in the wild.
