Pro Tips & Common Mistakes

• Consistent Grind Size: Using a burr grinder ensures a consistent grind size, which is crucial for even extraction.
• Temperature Control: Water that is too hot can scorch the coffee, while water that is too cold can result in a weak brew. Aim for 92°C to 96°C.
• Exact Brew Time: Timing is critical in a French Press. Over-extraction can lead to a bitter taste, while under-extraction results in a weak, watery coffee.
• Avoid Over-Filling: Do not overfill the French Press as it can lead to poor extraction and a bitter taste.
• Slow Plunge: Press the plunger slowly to avoid introducing turbulence that can affect the taste of the coffee.
