The Best Coffee Grinders for Cold-Brew-Ready Coarse Grinds

Cold brew coffee requires a coarse and consistent grind to ensure slow, even extraction for a smooth, low-acid coffee. A quality burr grinder is essential, as it allows you to precisely dial in coarse settings and repeat them. A poor grind, often produced by blade grinders that chop beans unevenly, can result in a bitter, silty, or weak brew.

Why Grind Consistency is Crucial for Cold Brew

The ideal grind size for cold brew is coarse, often compared to the consistency of rough breadcrumbs. Achieving a uniform particle size is critical for two main reasons:

• Optimal Extraction Rate: Cold brew steeps for 12 to 24 hours. A coarse grind slows down the extraction process, preventing the over-extraction of bitter-tasting compounds. This slow-and-steady approach results in a smoother, sweeter flavor profile. A fine grind would extract far too quickly, making the coffee harsh and bitter.
• Clean Filtration: Coarsely ground coffee is much easier to filter out after steeping. A uniform coarse grind prevents fine sediment from passing through the filter, resulting in a cleaner, clearer final product without unpleasant grit or cloudiness.

Key Features in a Cold Brew Grinder

• Coarse Grind Consistency: The most important feature is the ability to produce uniformly coarse particles. Many grinders struggle at coarser settings, creating a mix of "boulders and dust" that leads to uneven and poor extraction.
• Burr Type: Burr grinders are far superior to blade grinders for consistency.
  • Conical Burrs: Common in versatile home grinders, conical burrs are known for producing fewer fine particles and less heat. They can be more forgiving when dialing in a coarse setting.
  • Flat Burrs: Often found in higher-end, brew-specific grinders, flat burrs produce a very uniform grind size, which can result in a cleaner, brighter cup of coffee.
• Burr Material:
  • Steel Burrs: Durable and common in a wide range of grinders, steel burrs are often considered more suitable for coarser grinds.
  • Ceramic Burrs: These burrs stay sharp longer and are less thermally conductive, which helps prevent heating the beans during grinding. However, they can be more brittle.
• Low-Speed Motor: A high-torque, low-speed motor is preferable as it generates less heat and static. This helps preserve the coffee's delicate flavor and aroma, which can be negatively affected by excess heat.

Top Electric Burr Grinders

Baratza Encore / Encore ESP

Long considered a benchmark for entry-level burr grinders, the Baratza Encore is known for its consistent grind and durability. It features 40mm M2 conical steel burrs and 40 numbered settings. The updated 'ESP' model is optimized for a wide range, with settings 21-40 designed for filter coffee and coarse methods like cold brew. Its high-torque DC motor runs slowly to minimize heat and noise, and replacement parts are readily available.

Fellow Ode Gen 2

The Fellow Ode is specifically designed for brew methods like pour-over, French press, and cold brew (it does not grind for espresso). This focus allows it to excel at producing a consistent coarse grind. The Gen 2 model features large 64mm flat burrs, new anti-static technology for a cleaner workflow, and a larger 100-gram single-dose hopper. Its 31 grind settings (with 8-11 recommended for cold brew) provide professional-grade precision for a clean, balanced cup.

OXO Brew Conical Burr Grinder

A popular budget-friendly choice, the OXO Brew grinder offers excellent performance and ease of use. It features 40mm conical stainless steel burrs and 15 primary settings with additional micro-settings, allowing users to dial in the perfect coarse grind. A high-torque, low-speed motor prevents overheating the beans, and the stainless steel grounds container is designed to reduce static. It also includes a UV-blocking hopper to help keep beans fresh.

Fellow Opus

The Fellow Opus is a powerful all-purpose grinder suitable for everything from espresso to the coarsest cold brew. It features a 6-blade, 40mm conical burr set (C6-40 Burly Burrs™) and a high-torque, low-speed (350 RPM) motor. With over 41 precision settings, it offers great flexibility. It also includes anti-static technology and a magnetic catch cup for a cleaner experience.

This grinder features a digital interface with an electronic timer that allows for precise and repeatable dosing. It offers an extensive range of 60 grind settings, with settings 59-60 providing an ideal coarse grind for overnight immersion methods like cold brew.

Capresso Infinity Plus

The Capresso Infinity Plus is equipped with a commercial-grade solid steel conical burr set. Its gear-reduction motor minimizes speed to reduce heat and static, preserving the coffee's flavor and aroma. It offers 16 settings, including an extra-coarse setting specifically designed for methods like cold brew and French press.

Top Manual Burr Grinders

1Zpresso JX-Pro

For those who prefer a manual grinder, the 1Zpresso JX-Pro offers exceptional precision and speed. Its large 48mm conical burr set and fine adjustment (35 microns per click) make it easy to dial in a perfect coarse grind. It can grind a 60g batch quickly while remaining highly portable.

Timemore Chestnut C2

The Timemore C2 is a budget-friendly manual grinder that delivers a very even, coarse grind suitable for small-batch cold brew (around 24–28 clicks). It's an excellent choice for those who want quality on a budget without sacrificing consistency.

Hario Skerton Pro

An upgrade to a classic manual grinder, the Hario Skerton Pro features a simple stepped adjustment collar that can reach a coarse grind of 1400 µm. The included stabilizer plate keeps the axle steady, which significantly improves grind uniformity at coarser settings.

Care and Maintenance

• Brush out the burrs and chute weekly to prevent grounds buildup. Perform a deep-clean monthly using grinder-specific cleaning pellets.
• Store beans in an airtight container and fill the hopper only for immediate use. This reduces oil buildup and keeps beans fresher.
• Check burr alignment and sharpness yearly. Most brands sell replacement burrs for a reasonable price, which can significantly extend the life of your grinder.

Summary

For a great cup of cold brew, the right grinder is as important as the beans. The key is to use a burr grinder that can produce a consistent, coarse grind with minimal fines. An entry-level electric model like the Baratza Encore or OXO Brew is more than sufficient for delicious results. For those seeking the highest level of precision and clarity, a flat-burr grinder like the Fellow Ode provides exceptional uniformity, albeit at a higher cost. Finally, manual grinders like the 1Zpresso JX-Pro or Timemore C2 offer a fantastic way to save money and space without compromising on grind quality.
