Frequently Asked Questions

Q: What is the difference between the JAFFEE J0 and J1 manual coffee grinder models?

A: The J0 and J1 models share the same core 38mm burr platform and 3-bearing system but differ primarily in their burr core configuration — the J0 typically uses a 5-core burr while the J1 uses a 7-core burr. The 7-core burr in the J1 provides a slightly finer, more consistent particle size distribution, making it especially well-suited for espresso brewing. Both models offer stepless grind adjustment for full flexibility.

Q: Can I use the JAFFEE J0/J1 grinder to grind for espresso?

A: Yes! The JAFFEE J0/J1 is specifically designed to achieve the ultra-fine grind settings required for espresso. Its 38mm precision burr and stepless adjustment dial allow you to fine-tune the grind size to the exact level needed for a proper espresso extraction, giving you full control over your brew.

Q: Is the JAFFEE J0/J1 manual grinder suitable for travel?

A: Absolutely. The JAFFEE J0/J1 is built with portability in mind. Its compact, slim form factor and lightweight yet durable construction — combining wood, aluminium alloy, and stainless steel — make it an ideal travel companion for camping trips, office use, hotel stays, or any situation where a quality grind is needed away from home.

Q: How do I clean the JAFFEE J0/J1 manual coffee grinder?

A: The grinder's components can be disassembled for easy cleaning. Simply remove the burr assembly, brush away any residual coffee grounds with a soft cleaning brush, and wipe down the parts with a dry or slightly damp cloth. Avoid submerging wooden components in water to preserve the material finish.
