French press brewing places ground coffee directly in water before a mesh plunger separates most grounds from the drink. CoffeeBox's guide uses a four-minute steep as a practical starting point. The mesh permits more fine particles into the cup than a paper-filter preparation, which helps explain the textured result. It does not allow every component of the bean into the beverage.
Match the batch to the press's stated working capacity rather than assuming the printed cup count means full mugs. A 1:15 recipe, for example, pairs 30 grams of coffee with 450 grams of water. Wet the grounds evenly, follow a recorded steep and press slowly according to the maker's instructions. Coarse grinding is a conventional starting point, but no unexplained numerical setting transfers directly between grinder models.
Pour gently if you prefer less sediment, and evaluate the cup before changing a single factor. A longer steep is not the only explanation for bitterness, just as a short steep is not the only cause of a thin drink. Clean the screen and other components using the approved procedure. Do not replace the designed filter with an improvised material solely because it becomes blocked.
