Best Burr Grinder for Cold Brew

We'd point cold brew makers who steep large jugs toward this OXO, because the 12-ounce hopper means fewer refills and the 15 grind settings (with 43 micro-adjustments) reach the coarse end that long steeping wants. The 40mm stainless conical burrs, a two-year warranty and a one-touch start that remembers your last setting keep the routine simple, and the UV-tinted hopper suits a sunny kitchen.

Owners report that it grinds evenly and runs quietly, and that setup is easy. The complaints are the part to read carefully: owners report units breaking down within a couple of months, and a common complaint is that the grinder clogs and throws grounds around. That makes it a better fit for someone who will clean it regularly than for someone who wants zero upkeep.

This is the one we'd consider if the grinder also has to serve an espresso machine. It offers 48 grind settings, a 450 RPM low-speed motor, 40mm stainless conical burrs and a timer knob that runs up to 40 seconds, plus a 300g bean hopper, and it ships with a portafilter holder for 51mm and 58mm baskets. For cold brew, the extra-coarse end of the dial is the part that counts, and the long dial gives room to tune it.

Owners report even results, easy setup and a noise level that is acceptable, with static that is minimal at first. A common complaint is retention, with beans sticking inside the machine, and the anti-static cup is reported to lose its effect after a while. Tapping the side to clear grounds can nudge the dial, according to reviews, so re-check the setting if you do that. The OXO Brew Conical Burr Coffee Grinder 12 Oz has a simpler dial, though this one adds a portafilter holder.

The Amzchef is our pick for people who switch between cold brew, pour-over and espresso and like a bit of precision. A touchscreen lets you choose 2 to 12 cups or set grind time up to 40 seconds in half-second steps, and the 48 settings run ranging from espresso up through French press, pour-over and cold brew. The 40mm stainless conical burrs sit under a hopper that holds 10.6 ounces.

Owners report consistent grounds even from oily beans, quiet running, little static and burrs that come out for cleaning, and they like the instructions printed on the side. Compared with the Iagreea Conical Burr Coffee Grinder, it trades the portafilter holder for a screen and a stainless container, and it has the heaviest weight listed on this page.

The Fellow Opus is the most precision-minded grinder here. Its 48 mm conical burrs and stepless adjustment let you make tiny changes anywhere on the dial, which helps if you want to settle on one exact coarse setting for cold brew and also move to espresso. It is designed for near-zero retention, uses anti-static technology, stops on its own, and comes with two magnetic catch cups (one for espresso, compatible with 54 mm baskets) and tool-free burr access.

The listing carries no written owner reviews, but Amazon's summary of buyer feedback is positive on grind uniformity, speed, quiet running, ease of use and low retention. Buyers say it is much faster than previous models they have used. Set against the Amzchef Burr Coffee Grinder 48 Settings, it gives up a touchscreen and timer in exchange for a stepless dial and larger burrs. The listing gives a 2-year standard warranty.

The Cuisinart is the only flat-burr grinder here, and its 18-position selector spans from ultra-fine to extra-coarse, with the coarse end meant for French press and cold brew. A 500-watt motor, an 8 oz removable hopper and a chamber sized for up to 32 cups make it easy to prep a large batch, and it carries a limited 18-month warranty.

Owners report that it works quickly and is simple to set up, and owners say it copes well with the middle of the dial. The limitations are well documented, though: a common complaint is that it is loud, that it does not always grind every bean, and that it gets messy to operate and clean. Reports of it stopping after about nine months also come up. Next to the Ollygrin Electric Conical Burr Coffee Grinder, it is the noisier choice, so we see it as a fit for households that tolerate a louder machine.

The Ollygrin pairs 40-millimeter stainless conical burrs with a gear reduction motor for slow grinding and 30 grind settings, plus the option to select cups from 2 to 12. A 10-ounce hopper, a friction clutch that protects the gears from stray stones and built-in overheat protection round it out, and a rotary button handles operation.

Owners report excellent consistency, quieter running than expected, fast grinding and easy cleaning, including disassembly. Reviewers also say it performs well with dark, oily beans. The one limit stated in reviews is that the presets leave little room for fine-tuning at the very fine end for espresso, which matters less for cold brew. Against the OXO Brew Compact Conical Burr Coffee Grinder, its 10-ounce hopper holds far more than the compact OXO's 50 grams, though the very fine espresso end is not its strength.

The compact OXO suits kitchens where space is tight: it is listed at about 11 inches tall and holds 50 grams of beans in the hopper, enough for up to six cups. Its 15 settings plus 29 micro-adjustments, stainless conical burrs and chuteless design with burrs that come apart make cleaning accessible.

Owners report even, consistent grounds, quiet running and a good range of stepped grind settings. A common complaint is mess, particularly while assembling and taking the grinder apart, and static is reported during use. The 50 gram hopper is the smallest on this page, well below the 12 ounces on the OXO Brew Conical Burr Coffee Grinder 12 Oz, so it suits small cold brew batches best.
