Timemore Chestnut X: What It’s Good For and Who Should Buy It

Four months on my counter, tested side by side with a Niche Zero and a Baratza Sette 270. That’s the review window for the Chestnut X, Timemore’s electric flagship. It earns its price without pretending to be a Niche or a Baratza, and it’s the right pick for a specific buyer: someone doing both espresso and pour-over who doesn’t want two grinders cluttering the counter.

It’s not perfect. Most of the flaws are ones you can work around, though, and I’ll walk through exactly where it shines and where it doesn’t.

What the Chestnut X Actually Does Well

The stepless adjustment dial is the standout feature. You get real granularity here, which matters more than most reviews give it credit for. When I’m dialing in a new bean, I want to move in tiny increments, not jump from “too fine” to “too coarse” with nothing in between. The Chestnut X lets you nudge the burr set by fractions of a turn, and that precision shows up in your shots as fewer wasted dose-outs while dialing in.

The 48mm stainless steel burrs are the other reason this grinder punches above its price point. Timemore didn’t cheap out here. Retention is low: I’m getting under half a gram left in the chute after a dose, and that beats what I’ve measured on grinders twice the price. For reference, the SCA’s grind-size standards put espresso in the 200-300 micron range. Hit that range consistently and you’ve got a good grinder. The Chestnut X holds a tight distribution at espresso settings, tighter than I expected from a sub-$300 machine.

Where It Struggles

Noise. This thing is loud, louder than the Niche Zero, louder than most conical grinders in this price bracket. If you’re grinding at 6am before anyone else in the house is up, that’s a real consideration, not a minor one.

The other issue is speed at the coarse end. Grind for a French press or a big batch brew and you’ll notice more clumping than you’d get from a grinder built specifically for filter coffee. It’s not bad. It’s just not its strongest use case. If 80% of your brewing is pour-over or drip, there are better dedicated options.

Chestnut X vs. the Grinders People Actually Compare It To

The Niche Zero still wins on quiet operation and marginally better retention, but you’re paying a real premium for that last bit of refinement. If you’ve already got a Niche Zero on your wishlist and are trying to decide if it’s worth the jump, the honest answer is: only if noise or retention specifically bother you. The Chestnut X gets you 90% of the way there.

The Real Bottleneck

Here’s what I tell people who email me asking if the Chestnut X will fix their espresso: it won’t, if your machine or your technique is the actual problem. I’ve watched people buy this grinder expecting magic and get the same inconsistent shots because they’re still eyeballing their dose or using a tamper that doesn’t seat evenly.

Grind consistency is necessary, not sufficient. The CQI’s cupping methodology exists precisely because taste evaluation has to control for every other variable: water temp, brew ratio, freshness, before you can isolate what the grind itself is doing to flavor. Apply that same discipline at home. Weigh your dose. Weigh your yield. Time your shot. 18g in, 36g out, 27 seconds is a fine starting recipe for most light-to-medium roasts. If your ratios are inconsistent, no grinder fixes that.

What I will say: if your current setup is a blade grinder or an old-school Baratza Encore trying to pull espresso, the Chestnut X is a legitimate upgrade. That’s the actual bottleneck in most home setups: not the machine, the grind quality feeding it. Espresso is far more sensitive to particle distribution than filter coffee, and a grinder built for filter coffee will always show its limits under pressure.

Who Should Buy This Grinder

• You’re running one grinder for both espresso and pour-over and don’t want two machines taking up counter space.
• You want stepless adjustment but don’t want to pay Niche or Baratza flagship prices.
• Noise isn’t a dealbreaker. You’re not grinding next to a sleeping baby at 6am.
• You’ve outgrown a blade grinder or an entry-level burr grinder, and espresso’s become the priority now.

Who Should Skip It

• You mostly brew large-batch filter coffee. Look at a grinder built for that instead.
• Noise is a genuine constraint in your living situation.
• You’ve got the budget for a Niche Zero and the retention and quiet operation matter enough to justify the price gap.

My Recommendations

Timemore Chestnut X. My pick for anyone splitting time between espresso and pour-over who doesn’t want to own two grinders. The burr quality and retention numbers I measured hold up against grinders that cost twice as much.

Niche Zero. If quiet operation and near-zero retention matter enough to justify the price jump, this is the one I still reach for most mornings. I’ve run thousands of grams through mine with barely any maintenance drift.

Baratza Encore ESP. A solid budget alternative if you want dedicated espresso grinding without the Chestnut X’s noise level. Baratza’s published burr alignment tolerances are tight for this price point, and it shows in the cup.

Timemore Black Mirror Scale. Pair this with any grinder on this list. You can’t dial in a consistent shot without weighing dose and yield. Full stop.
