Buying Guide
When choosing the best coffee grinder for cold brew, you need to focus on a few key features that directly impact your brew’s quality. Cold brew is forgiving, but a consistent grind size is non-negotiable for a clean, sweet cup. Let’s break down what to look for.
Grind Consistency
The most critical factor is how uniform the grounds are. In cold brew, uneven particles extract at different rates, leading to a bitter or sour taste. Conical burr grinders are ideal because they crush beans between a moving and stationary surface, producing a consistent particle size.
Both the Ollygrin and OXO models feature 40mm stainless steel conical burrs, which are excellent for this purpose. We recommend looking for a grinder with a wide range of settings, as you’ll need a coarse grind for cold brew. For more insights, explore our top conical burr coffee grinders.
Grind Settings and Adjustability
Cold brew requires a coarse, even grind, but you also want the flexibility to experiment with other brewing methods. The Ollygrin offers 30 grind settings, while the OXO Brew provides 15 settings plus 43 micro-adjustments, giving you fine control. More settings mean you can dial in the perfect coarseness for your cold brew concentrate or ready-to-drink batch.
For cold brew, you’ll typically want a setting in the coarser range, but having micro-adjustments lets you tweak based on your steeping time and bean origin. This flexibility is a huge plus if you occasionally switch to French press or pour-over.
Durability and Motor
Grinding coffee beans, especially for a large batch of cold brew, puts stress on the motor. Look for a grinder with a gear reduction motor, like the Ollygrin, which spins slowly to reduce heat and friction. This preserves the delicate flavors in your beans and extends the grinder’s lifespan.
Additionally, consider safety features like overheating protection and a friction clutch. These protect the motor from damage if you accidentally grind a small stone. Both models include such protections, but the Ollygrin’s double safety system is a standout for peace of mind.
Ease of Cleaning and Capacity
Cleaning a grinder can be a chore, but it’s essential for preventing stale coffee oils from affecting flavor. Look for a grinder with a removable upper burr, like the Ollygrin, which can be lifted off for easy rinsing. The included brush helps dislodge grounds from crevices.
Capacity matters if you’re brewing a large batch of cold brew. The Ollygrin holds up to 10 ounces of beans, while the OXO Brew holds 12 ounces. A larger hopper means fewer refills, which is convenient when you’re preparing a week’s worth of cold brew.
Final Thoughts
Choosing the best coffee grinder for cold brew comes down to your personal brewing habits and budget. If you value a wide range of grind settings and robust safety features, the Ollygrin Burr Coffee Grinder is an excellent all-around choice. For those who prefer a larger capacity and the convenience of one-touch operation with memory settings, the OXO Brew Conical Burr Electric Coffee Bean Grinder is a reliable companion that will serve you well for years to come.
Frequently Asked Questions
What grind size is best for cold brew?
For cold brew, you want a coarse grind, similar to breadcrumbs or coarse sea salt. This prevents over-extraction and results in a smooth, sweet cup. Adjust the coarseness based on your steeping time; a longer steep may require a slightly coarser grind.
Can I use a blade grinder for cold brew?
While you can use a blade grinder, it’s not recommended. Blade grinders produce inconsistent particle sizes, leading to a bitter and muddy cold brew. A conical burr grinder, like the ones we reviewed, ensures uniform grounds for a cleaner extraction.
How fine should the grind be for cold brew concentrate?
For a cold brew concentrate, you’ll want a slightly finer grind than for a regular cold brew, but still coarser than a drip coffee grind. This allows for a stronger extraction without becoming bitter. Start with a medium-coarse setting and adjust to taste.
Do I need a special grinder for cold brew in 2026?
No, you don’t need a special grinder, but you need one with a coarse grind setting. Most burr grinders, including the Ollygrin and OXO Brew, offer the necessary adjustability. For more tips, check out our guide on coffee grinders for beginners to get started.
