Using a Timemore Grinder for Cold Brew: Grind Settings, Tips, and What to Expect

If you're wondering whether your Timemore grinder can handle cold brew, the answer is yes, and it does it surprisingly well. Cold brew requires a coarse grind, somewhere around the texture of raw sugar or coarse sea salt. Most Timemore hand grinders, from the C2 all the way up to the Chestnut X, can reach that coarse range without any problems. You just need to know where to set the dial.

I've been making cold brew with various Timemore grinders for a while now, and I've landed on some specific settings and techniques that produce a smooth, sweet concentrate every time. Let me share what works and what doesn't.

Best Timemore Grind Settings for Cold Brew

Every Timemore model uses a different click system, so the exact setting varies by grinder. Here are the cold brew settings I've found work best for each popular model.

Timemore C2 and C3

The C2 and C3 use a stepped adjustment with numbered clicks. For cold brew, set it to around 28 to 32 clicks from fully closed. Start at 30 and adjust from there. If your cold brew tastes bitter or harsh, go coarser (higher number). If it tastes flat and watery, tighten it up a few clicks.

Timemore Chestnut X

The Chestnut X has a much finer adjustment system with marked numbers on the dial. For cold brew, set it between 80 and 90 on the scale. The X produces a more uniform coarse grind than the C2 because of its higher-quality burrs, which means better extraction consistency in your cold brew.

Timemore Slim and Slim Plus

The Slim series handles cold brew well despite being designed primarily for pour-over and espresso. Set it to around 22 to 26 clicks for cold brew. The narrower burr set means slightly slower grinding at coarse settings, but the grind quality is still good.

The key thing to remember: these are starting points. Your beans, your water, and your steep time all affect the final cup. Adjust by 2 to 3 clicks at a time until you find your sweet spot.

Why Grind Size Matters So Much for Cold Brew

Cold brew extracts coffee through time rather than heat. You're steeping grounds in cold or room temperature water for 12 to 24 hours, so the extraction process is slow and gentle. This is why grind size is so important.

Grind too fine and you'll over-extract. The long steep time pulls out bitter compounds, tannins, and astringent flavors that hot water would dissolve quickly but cold water draws out slowly. The result is a harsh, unpleasant concentrate that no amount of dilution can fix.

Grind too coarse and you'll under-extract. The water can't penetrate the large particles well enough during the steep, leaving you with a weak, flat brew that tastes like slightly coffee-flavored water.

The sweet spot produces a concentrate that's smooth, naturally sweet, with chocolate and nut notes. You want particles that are uniform in size so extraction happens evenly across all the grounds. This is where Timemore grinders have an advantage over cheap blade grinders. The burr mechanism produces a much more consistent particle size.

My Cold Brew Recipe with a Timemore Grinder

Here's the exact method I use, and it produces reliable results every time.

Ingredients and Ratios

I use a 1:5 ratio by weight. That's 100 grams of coarsely ground coffee to 500 grams (500ml) of filtered water. This makes a concentrate that you dilute 1:1 with water, milk, or whatever you prefer.

For beans, I recommend medium or dark roast for cold brew. Light roasts can taste sour and thin when cold-brewed because the fruity acids don't develop the same way without heat.

The Process

Grind your coffee on the coarse setting described above. Put the grounds in a mason jar or French press. Pour the cold, filtered water over the grounds. Stir gently to make sure all the grounds are wet. Cover and put it in the fridge for 18 to 24 hours.

After steeping, strain through a fine mesh strainer first to catch the big particles, then through a paper filter (a regular drip coffee filter works fine) to remove the fines and sediment. The double filtration gives you a clean, smooth concentrate.

Storage

Cold brew concentrate keeps in the fridge for up to two weeks, though I think it tastes best in the first 7 days. After that, it starts developing stale, woody flavors. Make a batch on Sunday and you'll have cold brew all week.

Hand Grinding for Cold Brew: Is It Worth the Effort?

Let me be honest about this. Grinding 100 grams of coffee on a coarse setting with a hand grinder takes a while. On the Timemore C2, expect about 3 to 4 minutes of steady cranking. The Chestnut X is faster, maybe 2 to 3 minutes, because of its larger burrs and smoother mechanism.

If you're making cold brew once a week, it's totally manageable. If you're making it daily in large batches, you might want an electric grinder to save your arm.

The quality argument absolutely favors a Timemore over a blade grinder, though. A blade grinder chops beans into wildly uneven pieces, ranging from dust to boulder-sized chunks. That inconsistency means some grounds over-extract (bitter) while others under-extract (sour), and you end up with a muddled, harsh cold brew. The Timemore's burrs give you uniform particles, which means clean, balanced flavor.

Troubleshooting Common Cold Brew Problems

Bitter or Harsh Taste

Your grind is too fine. Go 3 to 4 clicks coarser. Also check your steep time. If you're going beyond 24 hours, dial it back to 18.

Weak, Watery Flavor

Your grind might be too coarse, or you're not using enough coffee. Try tightening the grinder 2 to 3 clicks, or increase your coffee-to-water ratio to 1:4 instead of 1:5.

Sour or Acidic Notes

This usually means under-extraction. Go slightly finer, steep longer (try a full 24 hours), or switch to a darker roast. Light roasts and short steep times are the usual culprits.

Cloudy or Silty Concentrate

This happens when fines get through your filter. The fix is simple: filter twice. First through a mesh strainer, then through a paper filter. If your Timemore is producing a lot of fines at coarse settings, the burrs might need cleaning. Coffee oil buildup between the burrs can cause uneven grinding.

FAQ

Do I need to calibrate my Timemore grinder before grinding for cold brew?

Yes, always start from a fully closed (zero) position and count clicks outward to your desired setting. To find zero on most Timemore models, tighten the adjustment dial gently until the burrs just barely touch and won't turn freely. That's zero. Then count clicks from there.

Can I use my Timemore Nano for cold brew?

The Nano works, but its small capacity (about 15 to 18 grams) makes it impractical for cold brew batches. You'd need to refill and grind 5 or 6 times for a single batch. The C2 or Chestnut models with larger hoppers are much better suited for cold brew volume.

Is hand-ground cold brew better than pre-ground?

Absolutely. Pre-ground coffee starts losing flavor within 15 to 20 minutes of grinding due to oxidation. When you grind fresh, you capture all the volatile flavor compounds that make cold brew taste sweet and complex. The difference is obvious in a side-by-side comparison.

How long should I steep cold brew with a coarse Timemore grind?

For the coarse settings I recommended (28 to 32 clicks on the C2), steep for 18 to 24 hours in the fridge. Room temperature steeping works too but finish in 12 to 16 hours, since extraction speeds up at warmer temperatures. Taste it at different time points to find what you prefer.

Wrapping Up

A Timemore grinder and cold brew are a great match. The consistent coarse grind gives you clean extraction, the manual process fits the slow, patient nature of cold brew brewing, and the results beat anything you'd get from a blade grinder or pre-ground coffee. Set your Timemore to the coarse range for your specific model, use a 1:5 ratio, steep 18 to 24 hours, and filter twice. That's the entire recipe for smooth, sweet cold brew at home.
