New Update Alert 🚨
A new TikTok trend—protein coffee (or “proffee”)—is now linked to health risks. The problem isn’t the drink itself. The danger comes when people let it sit too long in mugs or thermoses or reuse containers without washing them. Warm, protein-rich coffee creates the perfect breeding ground for bacteria, which can make you sick. That’s why we’ve updated our guide (2024) on how often you should clean your coffee mug. The message is simple: a dirty mug isn’t seasoned—it’s contaminated.
Why TikTok’s Protein Coffee Trend Is Risky
A recent Travel and Tour World report explains the dangers of “proffee.” Protein coffee spoils fast, especially in sealed mugs or thermoses. Once spoiled, it can cause illness. Add in high caffeine, sugar crashes, or protein sensitivities, and the risks grow even higher.
Takeaway: If your coffee contains protein powder, milk, or cream, wash your mug or thermos after every use.
How Often Should You Clean Your Coffee Mug?
-
Black coffee at home: Rinse after each use; deep clean weekly.
-
Coffee with milk, cream, or sugar: Wash thoroughly every time.
-
Protein coffee or travel mugs/thermoses: Rinse right away and deep clean daily.
-
Shared office mugs: Always wash after use.
Why Daily Cleaning Matters
An unwashed mug—especially one with milk or protein—quickly turns into a breeding ground for bacteria and mold. Thermoses make the problem worse because they trap moisture.
Yes, coffee oils can “season” a mug, but that’s very different from leaving residue behind. A quick rinse with hot water helps, but regular washing is the only way to stay safe.
Your coffee tastes better in a clean cup—and your health depends on it. Be sure to clean your mug or travel thermos daily.
