How to Use AeroPress Flow Control Filter Cap

Quick answer

The AeroPress Flow Control Filter Cap lets you control the brew time by stopping drip-through until you press, resulting in a cleaner, fuller-bodied cup.

Step-by-step brewing guide

1. 1. Prepare the cap and filter: Unscrew the standard cap from your AeroPress and replace it with the Flow Control Filter Cap. Place one paper micro-filter into the cap and wet it with a little hot water to seal it against the cap. Snap the cap into the bottom of the chamber. Make sure the filter is centered and wet – a dry filter can shift during pressing.
2. 2. Add coffee and water: Add your ground coffee (about 15-18g for a single cup) to the chamber. Pour hot water up to the desired level (usually the top of the chamber for a full cup). Stir gently to ensure all grounds are saturated. Do not overfill – leave a little room for the plunger. The cap holds the water, so you can steep longer than usual.
3. 3. Steep and press: Let the coffee steep for 1-3 minutes depending on your taste. When ready, place the plunger on top and press down firmly but steadily. The valve opens under pressure, releasing the brewed coffee into your mug. Press slowly – a fast press can cause channeling (water bypassing the grounds) and a bitter taste. The cap prevents dripping during steeping, so you can set a timer without worry.
4. 4. Clean up: Remove the cap and rinse it under running water. The paper micro-filter can be discarded. The cap is dishwasher safe, but hand washing prolongs the silicone valve life. Check the valve for coffee grounds after each use – debris can prevent it from sealing properly next time.
