Pro Tips & Common Mistakes

Here are some tips to enhance your brewing experience with coffee filters:

• Pre-Wet Filters: Always pre-wet your filter with hot water to remove any paper taste and ensure even water distribution.
• Grind Consistency: Ensure your coffee is ground to the correct size for the filter type to achieve optimal extraction.
• Water Temperature: Use water that is not too hot or too cold. Temperatures too high can extract bitter compounds, while temperatures too low can lead to under-extraction.
• Brew Time: Avoid over-extracting by keeping the brew time within the recommended range to maintain a balanced flavor.
• Clean Filters: Regularly clean and maintain your filters to prevent build-up and ensure the best taste.
