Manual Coffee Grinder – 20g Fluted Body, 5/6/7-Star Burr

At a Glance

A compact hand grinder for fresh coffee, one cup at a time. The fluted aluminum body is 50 mm across and holds about 18-20 g of whole beans - roughly one mug of pour-over. Choose a black or silver body, then pick the 5-Star, 6-Star or 7-Star stainless steel burr that matches how you brew.

Which Burr Should I Choose?

All three burrs are stainless steel and all of them adjust from fine to coarse. The star number refers to the burr's cutting-edge design: higher-star burrs are designed for finer, more even grounds.

Not sure? The 5-Star burr covers most everyday filter brewing. Results always depend on your beans, roast and recipe - see our coffee grind size chart for starting points.

Key Features

• Three burr options: 5-Star, 6-Star or 7-Star stainless steel, each available in black or silver.
• Fine-to-coarse adjustment: turn the dial to move between espresso-fine and French-press-coarse grounds.
• Secure fluted grip: the straight-groove texture on the aluminum body helps you hold it steady while you crank.
• Stainless steel crank, solid wood knob: a comfortable, steady turn.
• Removable grounds cup: pour the grounds straight into your brewer.
• No power needed: no battery or outlet - at home, at the office or on the road.

How to Use

1. Remove the top cover and add up to about 18-20 g of whole beans.
2. Set the adjustment dial - start in the middle, then attach the crank.
3. Hold the body steady and turn the crank clockwise until it spins freely.
4. Remove the lower cup and pour the grounds into your brewer. Brew, taste, then go finer or coarser in small steps.

Care

After use, brush out loose grounds with a dry, soft brush. Do not immerse the grinder or rinse the burr assembly; if any part gets wet, let it dry completely before reassembling. More tips in our coffee grinder cleaning guide.

FAQ

Which burr should I choose?

For pour-over, drip and French press, choose 5-Star. For AeroPress, moka pot and finer pour-over, choose 6-Star. If you mainly want very fine, espresso-style grinds, choose 7-Star. Every burr still adjusts across the full fine-to-coarse range.

Can I change the grind size?

Yes. Turn the adjustment dial toward fine or coarse. Make small changes and test with your own beans and brewer.

How much coffee does it hold?

About 18-20 g of whole beans, enough for one mug of pour-over. Actual fill varies with bean size and roast.

Is it good for travel?

Yes. It is about 165 mm tall and 50 mm across and needs no power, so it packs easily for trips, camping or the office.

Does it need charging?

No. It is operated entirely by the hand crank.

What are the shipping and return terms?
