- Ignoring Brew Ratios: Users often overlook the importance of the coffee-to-water ratio, which can lead to either overly weak or bitter coffee. Experimenting with different ratios can help find the perfect balance for each size brew.
- Not Preheating the Machine: Some coffee makers require preheating to achieve optimal brewing temperatures. Skipping this step can result in under-extracted coffee that lacks flavor and aroma.
