Product Overview
The Tuni G2 Conical Burr Coffee Grinder is a compact, espresso-focused electric grinder for home use. It suits enthusiasts chasing better coffee. A patented anti-static 40mm conical burr, 70 grind settings, programmable single and double shot modes and a portafilter holder deliver precise, consistent grinds from espresso to French press.

What makes a burr grinder worth it? How consistent and adjustable the grind is, how well its espresso features and capacity work, how easy it is to live with and clean, and who it really suits. Grind quality comes from the conical burr and 70 settings. Espresso focus comes from the programmable shots and portafilter holder. Daily use is helped by the anti-static, easy-clean design. Well-featured and precise, it raises your home coffee, with a couple of honest notes about its focus below.

Key Features
Espresso to French press, with 0.5-second dose steps.
40mm burr at a low 400 RPM for consistent, cool grinding.
Single and double shot modes with repeatable doses.
Detachable holder for 51 to 58mm portafilters, or a dosing cup.
Large hopper, anti-fingerprint finish, built-in cleaning brush.
Design and Build Quality
Precise, consistent grinding sits at the center of the design. At its heart is a patented anti-static 40mm conical burr system, which delivers precise, consistent grinds for espresso, drip or French press. It runs at a deliberately low 400 RPM. That low speed minimizes static and heat buildup and keeps the grinding temperature stable, both of which matter for consistent, good-tasting coffee, since heat and static are the enemies of a clean, even grind. Adjustability is generous. It offers 70 grind settings, so you can fine-tune from fine espresso to coarse French press. You can also customize the grind time in 0.5-second increments for dialing in the exact dose. A quality conical burr, low-speed anti-static grinding and fine 70-step adjustment separate a real burr grinder from a blade grinder that just chops beans unevenly.
Its features lean clearly toward espresso and everyday convenience. Two programmable cup modes handle dosing. A single shot defaults to 12 seconds for about 12 to 13 grams of grounds. A double shot runs 16 seconds for about 18 to 19 grams, so espresso users get consistent, repeatable doses. A detachable portafilter holder, compatible with 51 to 58mm portafilters, lets you grind directly into your portafilter. Prefer larger quantities? Use the included dosing cup to collect them. Despite a compact footprint that stores easily, it carries a large 250-gram (8.8-ounce) bean hopper plus an extra 100-gram grounds container, so it holds plenty. Practical touches round it out. An anti-fingerprint stainless steel finish keeps it looking clean. A soft brush attached to the hopper lid clears residual grounds and prevents clogs. It ships with the grinder, a dosing cup, a hopper bellow, a dosing ring, the portafilter holder, two soft brushes and a manual.
Performance in Everyday Use
This grinder delivers the thing that most improves home coffee: a fresh, even, adjustable grind. The conical burr grinding at a low 400 RPM produces the consistent particle size that is the foundation of good coffee. Your espresso, drip or press coffee extracts evenly and tastes cleaner and better than beans hacked unevenly by a blade grinder. Meanwhile, the anti-static, low-heat design keeps the grind tidy and the flavor stable, rather than scattering static-charged grounds everywhere and heating the coffee. Real, fine control comes from the 70 settings plus 0.5-second time adjustment. Dial in exactly the grind and dose you want for your brew method and beans, which is what enthusiasts, and especially espresso makers, need to chase the perfect shot. The espresso focus genuinely shows. Programmable single and double shot modes with sensible default doses, plus a portafilter holder that grinds straight into 51 to 58mm portafilters, make pulling consistent shots far easier and less messy than grinding into a cup and transferring. With the large 250-gram hopper, you are not refilling constantly. The compact size suits small kitchens. The anti-fingerprint finish and the built-in cleaning brush keep it looking good and running clean. For anyone serious about home coffee, it is a real, tangible upgrade.
Consider its focus and the realities of a burr grinder. It is clearly designed with espresso in mind: programmable shots, portafilter holder, doses quoted in grams. So espresso and manual-brew enthusiasts get the most from it. Someone who only makes a big batch of drip will use fewer of its features, though its adjustability still serves any method well. As with any grinder, getting the best results means dialing in the grind for your beans and brew. The perfect setting varies by bean, roast and method, so expect some experimentation rather than a single magic number, which is part of the craft. Being an electric burr grinder, it makes some noise, as any grinder does. It also benefits from regular brushing out, which the included brush makes easy, to keep grounds fresh and prevent clogging. And while it holds a generous 250 grams, it is a compact home grinder rather than a heavy commercial machine, which suits its purpose. None of this counts against it; it is simply a precise, espresso-leaning home burr grinder. On those terms, it is a genuinely capable, well-equipped and precise grinder that meaningfully upgrades your home coffee.

Frequently Asked Questions
Why is a burr grinder better than a blade one?
A conical burr grinder crushes beans to a consistent, even particle size, which is the foundation of good coffee, so it extracts evenly and tastes cleaner and better. A blade grinder just chops beans unevenly. This model also grinds at a low 400 RPM with an anti-static design to minimize heat and static for a tidier, more consistent grind.
Is it good for espresso?
Yes, it is clearly designed with espresso in mind. It has programmable single and double shot modes (single about 12 seconds for 12 to 13 grams, double about 16 seconds for 18 to 19 grams) and a detachable portafilter holder compatible with 51 to 58mm portafilters so you can grind straight into your basket. It also handles drip and French press via its 70 settings.
How adjustable is the grind?
Very. It offers 70 grind settings covering everything from fine espresso to coarse French press, and you can also customize the grind time in 0.5-second increments to fine-tune your dose. As with any grinder, the ideal setting varies by bean and brew, so expect a little dialing in.
How much does it hold, and is it easy to clean?
It has a large 250-gram (8.8-ounce) bean hopper plus a 100-gram grounds container, despite a compact footprint. It has an anti-fingerprint stainless finish and a soft brush attached to the hopper lid for clearing residual grounds and preventing clogs, so it is easy to keep clean and running fresh.
What comes with it?
The grinder, a 100-gram dosing cup, a hopper bellow, a dosing ring, the portafilter holder, two soft brushes and a user manual, so you get both the portafilter and dosing-cup options plus cleaning tools in the box.
