Key specs explained for Timemore S3
Grind Settings: 0.015mm per click
This value indicates the precision of your adjustment mechanism. Each turn of the adjustment ring changes the gap between the burrs by exactly 0.015 millimeters. This allows you to make micro-adjustments to your grind size. You benefit from this when dialing in espresso, where small changes significantly affect extraction. It offers finer control than grinders with coarser click increments, helping you achieve consistent results for sensitive brewing methods.
Burr Material: Stainless steel
The grinding mechanism uses stainless steel burrs rather than ceramic or aluminum. Stainless steel provides high durability and resistance to corrosion. It maintains its sharpness over time, ensuring consistent particle distribution as you grind more coffee. This material choice supports long-term performance. You get reliable results for various brew styles, from coarse French press to fine espresso, without the burrs wearing down quickly compared to softer materials.
Power Source: Manual
This grinder operates without electricity or batteries. You provide the energy by turning the handle. This design eliminates noise and vibration associated with electric motors. It gives you direct tactile feedback on the grinding process. You can adjust your speed and pressure to suit the coffee beans. This makes it suitable for quiet environments or travel, as it requires no power outlet and offers full control over the grinding action.
Adjustment Type: External Adjustment
The grind setting is changed by twisting an external ring rather than opening the grinder. This allows you to adjust the settings quickly and cleanly. You can change your grind size on the fly without touching the internal burrs or spilling coffee. This design enhances convenience and speed. It is particularly useful when switching between different brewing methods throughout the day, keeping your workspace tidy and your workflow efficient.
