Frequently Asked Questions

How long do coffee beans stay fresh after grinding?

Ground coffee starts losing flavor within 15-30 minutes. For best results, grind only what you need just before brewing.

How often should I clean my grinder?

Clean your grinder every 1-2 weeks for regular use. More frequently if you use oily or flavored beans.

Can I use a food processor to grind coffee?

While possible, it's not recommended as it produces very inconsistent results and can heat the beans excessively.
