Tuni G3 64mm Flat Burr Grinder

In this Tuni G3 64mm flat burr grinder review, the verdict is simple: the Tuni G3 is the best flat burr espresso grinder under $200, and it ranks sixth of nine in our guide. It pairs 64mm stainless steel flat burrs with 100 stepped grind settings and a 260 watt motor for $199. That combination is rare at this price, where most rivals use smaller conical burrs. The Tuni G3 measures 9.8 by 5.9 by 15.6 inches and weighs 7.3 pounds, so it fits a normal counter without dominating it. It holds 4.4 stars from 92 Amazon ratings. This grinder suits home baristas who want flat burr clarity and dual hoppers without spending $300 or more.

Day to day, the two hoppers do the heavy lifting. The 250g hopper handles bulk grinding for drip or cold brew, while the 50g single dose hopper and bellow blower suit espresso, so you can keep two roasts loaded at once. Meanwhile, the LED touchscreen lets you customize grind times for single shot, double shot and continuous grinding, which means you can grind straight into the included dosing cup or the portafilter holder without a separate scale. The 64mm flat burrs spin on a wider surface than conical burrs, cutting beans fast and limiting heat buildup. In practice, the anti-static system drops grounds in a tight stream instead of scattering them across the counter.

At $199, the Tuni G3 undercuts every other flat burr grinder in our guide, and the box adds a 100g dosing cup, dosing ring, portafilter holder and two brushes, so there is little left to buy. However, 92 ratings is a thin base, which means long term durability is less proven than on the Breville Smart Grinder Pro or the Baratza models ranked nearby. Also, the 100 settings are stepped, so the smallest espresso adjustments take a click rather than a nudge. Even so, a 1 year warranty with lifetime tech support softens that risk. If dual hoppers and 64mm flat burrs under $200 are what you want, this is the one to get. Skip it if you chase stepless micro adjustments.
