Key Takeaways
| Mineral Buildup | Descale regularly to remove mineral deposits that dull flavor. |
| Residue & Oils | Clean the brew unit to eliminate oils and residue affecting taste. |
| Water Quality | Use filtered or bottled water for better flavor. |
| Reusable Filter | Ensure your reusable filter is clean and properly installed. |
Check and Refill Water Reservoir
Start by ensuring your water reservoir is filled with fresh, clean water. Old or mineral-heavy water can impact flavor. Empty and refill with filtered or bottled water if necessary.
Clean the Brew Unit and Needle
- Turn off and unplug your Keurig for safety.
- Remove the water reservoir and rinse it thoroughly.
- Use a paperclip or the cleaning tool that came with your brewer to clear the needle of any clogs or coffee grounds.
- Wipe the brew head and surrounding area with a damp cloth to remove residue.
Descale Your Keurig
Mineral deposits can cause poor flavor. Descale your machine every 3-6 months using a descaling solution or a mixture of equal parts water and white vinegar.
- Fill the water reservoir with the descaling solution or vinegar mixture.
- Run a brew cycle without a K-Cup, discarding the liquid afterward.
- Repeat until the reservoir is empty.
- Rinse thoroughly by running multiple cycles with fresh water to remove any residual taste.
Use the Reusable Filter or Clean It
If you use a reusable filter like the My K-Cup®, ensure it’s clean and free of old grounds. Rinse it thoroughly after each use and occasionally soak in warm, soapy water to remove oils that can affect flavor.
Adjust Brew Settings & Check Coffee Quality
Make sure you’re using the right brew size and fresh coffee grounds. For stronger flavor, select a larger brew size if available, or use a slightly finer grind for ground coffee filters.
