How to Use a Flower Dripper for Pour-Over Coffee

Quick answer

To use a flower dripper like the E&B Lab Flower Dripper, place a Chemex or Hario V60 paper filter inside, rinse it, add coffee grounds, and pour hot water in a controlled spiral. The flower-shaped petals hold the filter securely and prevent collapse.

Step-by-step pour-over with a flower dripper

1. 1. Set up the dripper and filter: Place the flower dripper on your mug or carafe. Insert a Chemex or Hario V60 paper filter. The longer petal should sit against the filter seam to hold it open. Make sure the filter is fully open and not folded over the petals.
2. 2. Rinse the filter: Pour hot water (just off the boil) through the filter to remove paper taste and preheat the dripper and vessel. Discard the rinse water. A common mistake is skipping the rinse — this can leave a papery taste in your coffee.
3. 3. Add coffee grounds: Add medium-fine ground coffee (similar to table salt). Use a 1:16 coffee-to-water ratio — for example, 15 grams of coffee to 240 grams of water. Grind too fine and the brew will stall; too coarse and it will be weak.
4. 4. Bloom the coffee: Pour twice the coffee weight in water (e.g., 30 grams for 15 grams of coffee) in a slow spiral. Wait 30–45 seconds for gases to release. If you skip the bloom, you'll get uneven extraction and sour notes.
5. 5. Continue pouring in stages: After the bloom, pour the remaining water in 2–3 stages, keeping the water level steady. Pour in a spiral from the center outward, avoiding direct contact with the filter. Pouring too fast or directly on the filter can cause channeling and a bitter taste.
6. 6. Let it finish dripping: Allow all water to pass through the grounds. Total brew time should be 2:30–3:30 minutes. Remove the dripper and enjoy. If the brew finishes too quickly, grind finer; if it stalls, grind coarser.

• E&B Lab Flower Dripper - V60/Chemex: The E&B Lab Flower Dripper is Italian-made and designed to house both Chemex and Hario paper filters. The longer petal grips the filter while shorter petals support it during brewing. This means you can use either filter type without adapters, and the filter stays in place without collapsing.
