Timemore Millab M01

What it does well

Particle consistency is the standout. Coffee Chronicler's analysis, run on a particle analyzer, showed the Pineapple burr gives few fines and boulders with most particles in the middle range. The reviewer says the pattern resembles a very consistent flat-burr grinder rather than a conventional conical, which matches Timemore's stated goal of getting flat-burr performance from a cone.

Build quality is premium. Coffee Chronicler lists aluminum and steel with only a small plastic accent, a textured body that stops it spinning in your hand, and a lock-in catch cup that does not detach on a bump but comes off easily. Eight Ounce Coffee lists a 50 g catch cup and a 35 to 50 g hopper. The maker adds custom P7 bearings with runout as low as 3 microns, and a finest-setting burr gap of 0.0725 mm.

It holds clarity at high extractions. In head-to-head cups against the 1Zpresso K-Ultra, Coffee Chronicler found the M01 let the reviewer push extraction higher while keeping a clear, pleasant aftertaste, where the K-Ultra fell apart sooner.

It reaches the extremes. Coffee Chronicler says the grinder is fine enough for espresso at 9 bar, with shots described as focused and intense, and that it handles very coarse settings if you release the burr and go past the nominal maximum. Blending a coarse and a medium grind gave the reviewer the best cups.

Where it falls short

It is heavy. At 1.1 kg with a straight handle, Coffee Chronicler found it a workout for both arms, particularly for espresso, and rated it less enjoyable than the Kinu M47 and the 1Zpresso J-Ultra, though nicer than the Comandante C40.

It is slow. Coffee Chronicler timed about 35 seconds for a 20 g pour-over dose and 55 to 60 seconds for 16 g of espresso, slower than many modern hand grinders.

Everyday cups are not outstanding. Within the usual 18 to 20 percent extraction range, Coffee Chronicler found the M01 delivered complexity with low bitterness but came across as somewhat generic, without the flavor separation of SSP burrs or the focus of the ZP6. It did better at the extremes: very coarse settings at low extraction, or blended grind sizes. That advice suits tinkerers more than beginners.

Espresso dial-in takes care. Coffee Chronicler reports one click can shift shot time by about 10 seconds, and that the grinder suits light and medium roasts better than dark ones. The reviewer also found the tight handle fit and small, hard-to-read numbers awkward.

Who should buy it, and who shouldn't

Buy it if you like beautiful, solid equipment, brew pour-over or pull espresso, and enjoy experimenting with extraction and blends. Coffee Chronicler says it is best for enthusiasts.

Skip it if you want an easy daily hand grinder, are new to hand grinding, or have limited grip strength. Coffee Chronicler does not recommend it for beginners and says buyers who want practical ergonomics and conventional performance have cheaper options.

How it compares

The 1Zpresso K-Ultra is the grinder Coffee Chronicler found more well-rounded, especially for espresso, and a tough grinder to beat. The 1Zpresso ZP6 gives a more focused, clearer cup, while the M01 offers more body and complexity.

The 1Zpresso J-Ultra is the usual espresso-first comparison, with an 8-micron external dial, and the Kinu M47 Classic is the stepless alternative Coffee Chronicler calls more enjoyable to use.

Owning it

Expect to learn its dial. The scale runs from 1 to 10 with ten clicks between numbers, per Coffee Chronicler, and espresso sits near 0.5 to 1. Our guide to dialing in a new grinder covers a sensible routine.
