Timemore Chestnut G1 Plus: What You Need to Know Before You Buy
The Timemore Chestnut G1 Plus is a hand grinder that sits in an interesting middle ground. It's not the cheapest option out there, and it's not trying to compete with grinders that cost three times as much. What it is is a well-built, capable hand grinder that punches above its price point in some meaningful ways. If you're trying to figure out whether it's worth your money, the short answer is: yes, for most people who want a capable travel or home hand grinder.
I want to walk you through what makes the G1 Plus different from standard hand grinders, how the burr set performs across different brew methods, who it makes sense for, and where it falls short. By the end, you'll have a clear picture of whether this fits your coffee setup.
What Is the Timemore Chestnut G1 Plus
Timemore is a Chinese grinder brand that's put out some genuinely impressive products over the last few years. The Chestnut line is their flagship hand grinder series, and the G1 Plus sits in the upper-middle tier of that lineup.
The "Plus" in the name refers to an upgraded burr set compared to the standard G1. Timemore swapped out the original stainless steel burrs for a set with a sharper edge geometry. The burr diameter is 38mm, which is standard for hand grinders in this price range.
What's In the Box
When you open the G1 Plus, you get the grinder itself, a cleaning brush, and a small manual. The grinder comes apart easily for cleaning. The top section unscrews to reveal the burr carrier, and the adjustment ring sits just below the top cap.
The body is aluminum with a matte finish. It feels solid without being heavy. The catch cup has enough capacity for a standard double shot or a pour-over dose of around 20-25 grams.
How the Adjustment System Works
Timemore uses an external adjustment ring that clicks into numbered positions. The G1 Plus has 30 clicks per rotation, and most people settle their espresso grind somewhere in the 10-15 range, with pour-over around 20-25 clicks. The clicks are tactile and audible, which matters when you're adjusting by feel.
One thing worth knowing: the G1 Plus doesn't have a true stepped dial with discrete numbers printed on it. You count clicks from the zero point (grinding burrs touching). This takes about 30 seconds to get used to and then becomes completely intuitive.
Grind Quality and Consistency
This is where the G1 Plus earns its reputation. The upgraded burr set produces a grind that's significantly more uniform than what you get from entry-level hand grinders like the Hario Skerton or the Rhinowares.
I ran the G1 Plus through a few scenarios. For pour-over, the grind size distribution is tight enough that you get clean, sweet extractions without the bitterness that usually signals too many fines. For French press, the coarse setting works well, though you'll still get some fines in the cup if you're particular about clarity.
Espresso Performance
Espresso is where hand grinders get tricky, and the G1 Plus handles it better than most at this price. The grind at espresso settings is fine enough for a quality shot on a home machine, and the consistency is good enough that you can actually dial in and repeat results.
That said, if espresso is your primary brewing method, I'd suggest looking at either the Timemore Chestnut C3 Pro or checking out the options in our best coffee grinder roundup, because the G1 Plus is designed as a versatile grinder rather than an espresso specialist.
Manual Grind Experience
At 20 grams, the G1 Plus takes me about 45-60 seconds to grind for pour-over. That's pretty average for a 38mm burr hand grinder. Espresso doses are a bit harder because of the finer setting requiring more torque, but it's still manageable for daily use.
Build Quality and Durability
The G1 Plus is built to last. The aluminum body feels substantial, the burr carrier doesn't wobble, and the adjustment ring doesn't slip during grinding. These are things that frustrate people about cheaper hand grinders.
The axle is stainless steel and runs through a set of bearings that keep the burrs aligned. Wobble in the burr is one of the main contributors to inconsistent grinds, and Timemore addressed this with a dual-bearing design that's noticeably more stable than single-bearing alternatives.
The handle folds flat for storage and travel, which is a practical touch. The folded grinder fits in most laptop bags without issue.
Long-Term Reliability
Hand grinders don't have many moving parts to fail. The main thing that wears over time is the burr set. Timemore sells replacement burrs separately, and they're reasonably priced. You'd realistically replace them after 2-3 years of daily use, depending on how much coffee you grind.
Who the G1 Plus Is For
The G1 Plus fits a specific kind of coffee drinker well. If you're someone who:
- Travels regularly and wants to grind fresh coffee on the road
- Works from home and doesn't want to disturb anyone with an electric grinder at 7am
- Is getting serious about coffee but isn't ready to spend $150-200 on an electric grinder
- Wants one grinder that handles both pour-over and occasional espresso
...then the G1 Plus is a strong choice.
It's less ideal for someone who grinds large batches every day (the catch cup capacity is limiting), or for someone whose entire coffee practice centers on pulling consistent espresso shots (where a dedicated electric burr grinder makes more sense).
Compared to Other Hand Grinders
At this price point, the main competitors are the 1Zpresso JX, the Kinu M47 Simplicity, and Timemore's own C3 Pro. The G1 Plus is competitive with all of them on grind quality. Where it wins is in its form factor and build feel. Where it loses is on adjustment precision compared to the Kinu and some 1Zpresso models, which have finer adjustment increments.

Cleaning and Maintenance
Cleaning the G1 Plus is straightforward. You unscrew the top section, pull out the upper burr carrier, and brush out any retained coffee from both burrs and the inside of the burr chamber. The whole process takes about 2 minutes.
Timemore recommends cleaning the burrs every 200 grams of coffee ground. In practice, a weekly clean is fine for most people unless you're grinding dark oily roasts, which can gum up the burrs faster.
Seasoning New Burrs
New burrs from any grinder need a break-in period. The G1 Plus is no different. Grind about 100-150 grams of coffee before you start critically evaluating the grind quality. The sharp edges on fresh burrs sometimes produce a slightly different particle distribution that evens out once the edge geometry settles.
Frequently Asked Questions
Is the Timemore Chestnut G1 Plus good for espresso? Yes, it can produce an espresso-fine grind, and the consistency is good enough to pull respectable shots. That said, it's more versatile than it is specialized. If espresso is your primary focus and you want the most dialed-in results possible from a hand grinder, you might look at options with finer adjustment increments.
How does the G1 Plus compare to the Timemore C3 Pro? The C3 Pro uses a different burr geometry optimized slightly more for filter coffee, while the G1 Plus uses the upgraded 38mm burrs that perform better across the full range. The G1 Plus is generally considered the better all-rounder between the two.
Can you adjust the grind size without taking the grinder apart? Yes. The external adjustment ring sits on the outside of the top section and can be turned while the grinder is fully assembled. You count clicks from your zero point.
How long does it take to grind a full cup's worth of coffee? At a pour-over setting, 20 grams takes roughly 45-60 seconds for most people. Finer settings for espresso take a bit longer because of increased resistance.
The Bottom Line
The Timemore Chestnut G1 Plus is a genuinely good hand grinder that delivers on its promise. The upgraded burr set makes a real difference in grind uniformity compared to earlier Timemore models, the build quality is solid, and the overall experience of using it daily is pleasant rather than tedious.
If you're buying your first serious hand grinder, or upgrading from something like a Hario or a cheap blade grinder, the G1 Plus will feel like a step up in every measurable way. Buy it with realistic expectations, keep the burrs clean, and it should serve you well for years.
