Wetting your coffee filter before brewing coffee removes any residual taste from the paper, improving flavor. More than that, it also affects the extraction process.
A wet coffee filter helps regulate water flow during brewing and allows water to interact with the ground more evenly, resulting in optimal flavor extraction.
Even at a basic level, damp coffee filters perform more efficiently than dry ones since it adheres better to your coffee machine, preventing slips or displacement when brewing.
Next time you brew a cup, first place the filter on the machine, then pour hot water over it and let it sit for a few seconds. Don’t drench it; a quick rinse will suffice.
After rinsing, discard the hot water before adding your coffee grounds and starting your brew. You’ll be pleasantly surprised by the improvement in taste.
