New to the category? Here’s a straightforward introduction to what a manual burr coffee grinder actually is, and how to get the most out of one — using the Aeirisse Divellence to walk through the basics.
What makes it a “burr” grinder
Unlike blade grinders, a burr grinder crushes beans between two surfaces — in the Divellence’s case, a 38mm conical steel burr with a 6-star configuration — producing consistent particle sizes instead of random chunks and dust. This is the single biggest factor separating a good grinder from a bad one. Our burr grinder vs. blade comparison covers exactly why this distinction matters so much for flavor.
What makes it “manual”
No motor, no cord. You turn a hand crank, and the burrs do the work. It’s slower than an electric grinder, but that slower pace keeps the beans cooler and the flavor more intact — a trade-off most people find worth it once they taste the difference.
The parts you’ll actually interact with
- Hopper — where whole beans go (20–25g capacity on the Divellence)
- Adjustment ring — sets grind size (72 clicks, 0.016mm per click)
- Handle — what you crank (walnut wood on the Divellence, for grip and comfort)
- Catch cup — collects the ground coffee (magnetic attachment keeps it secure while grinding)
Your first setup
- Twist the adjustment ring to a medium setting (around click 50–60) for your first grind.
- Add beans to the hopper — start with a small batch, around 18g.
- Crank steadily and evenly until you feel resistance ease, meaning the beans are ground.
- Empty the catch cup and brew.

A few beginner tips
- Finer grind = faster brewing methods (espresso). Coarser grind = longer steep times (French press, cold brew).
- Clean the burrs every 7–10 uses to keep flavor consistent.
- Note your click settings once you find ones you like — repeatability is one of the biggest advantages of a quality manual burr grinder.
- Don’t rush the crank. A steady, even pace produces a more consistent grind than fast, forceful cranking.
What to expect as you get comfortable
The first week or two is about learning how your specific grinder responds to adjustment. After that, most people settle into two or three go-to settings for their regular brew methods and rarely need to think about it again. Once you’re ready to go deeper on espresso specifically, our manual espresso grinder guide covers click ranges by setting.
