Why Cleaning Your Grinder Isn’t Optional
Most people assume a grinder’s job is mechanical — grind beans, brew coffee, repeat. But here’s the truth: your grinder is a flavor filter. And when it’s dirty, it filters out everything good.
Most grinders don’t die from age — they choke on neglect. Coffee oils oxidize fast, turning your grinder into a breeding ground for rancid flavors. But here’s what no one tells you: those same oils trap micro-particles that ferment inside the machine. This isn’t just bad for taste — it sabotages the very quality you paid for in specialty beans.
If you care about clean supply chains and honest coffee, it starts with clean tools. A dirty grinder disrespects the farmer, the roast, and your brew.

You don’t need a toolkit or an afternoon to clean your grinder — just one minute and a bit of intention.
How Often Should You Clean — And What Happens If You Don’t?
Let’s be honest — most people wait until their grinder smells off to clean it. By then, you’ve already corrupted dozens of cups.
For home users, a quick wipe after every use and a deep clean every 1–2 weeks is the sweet spot. But here’s what’s rarely discussed: bean origin matters. High-altitude Colombian beans? More natural oils. More buildup.
For a thorough breakdown, this MasterClass guide covers cleaning burr grinders step by step.
Consistency in cleaning is consistency in quality. Don’t let buildup dull your ritual.
Conclusion: Small Habit, Big Impact
A clean grinder doesn’t just make better coffee — it shows respect for the entire journey, from farmer to cup. It’s a small, often ignored habit that separates casual drinkers from true coffee people. Clean gear. Clean flavor. No excuses.
