Burr Grinder vs Blade Grinder
A blade grinder chops beans into a mix of dust and chunks. A burr grinder crushes them to a consistent size, which is what lets coffee extract evenly.
| Burr grinder | Blade grinder | |
|---|---|---|
| Consistency | Even particle size | Uneven, dust and boulders |
| Taste impact | Balanced extraction | Sour and bitter at the same time |
| Grind settings | Repeatable settings | Controlled only by time |
| Espresso | Espresso-capable models exist | Not suitable |
| Heat | Low on most models | Spinning blade warms beans |
| Price | Higher, manual burrs are affordable | Low |
Choose Burr grinder if
- You want noticeably better coffee
- You brew pour-over or espresso
- You want to adjust grind for different methods
Choose Blade grinder if
- You only need ground coffee occasionally
- You grind spices as well
- Budget is extremely tight
The bottom line
A burr grinder is the single upgrade that most improves home coffee. If budget is tight, a manual burr grinder costs little more than a blade grinder and grinds far more evenly.
