How to Make Why Specialty Ep. 1 — Cup of Excellence Bypass Pour-Over

What you need

• Pour-over dripper
• Paper filter
• Scale
• Gooseneck kettle
• Server or carafe
• Spoon or stirring stick
• Serving cup
• Ice and ice-filled glass (iced version only)

Method

1. Place the paper filter in the dripper and rinse it with enough hot water to seat the filter completely against all walls of the dripper, then discard the rinse water.

   Expert tipUse a generous pour during rinsing so the filter makes full, wrinkle-free contact with the dripper — incomplete seating creates bypass channels that produce uneven extraction.

2. Add the ground coffee to the rinsed dripper and gently tap or level the bed so the surface is flat and even before you begin pouring.

3. 0:00 — HOT RECIPE

   Pour 45 g of water evenly over the grounds to saturate all the coffee particles, then use a spoon to stir so that every particle is fully wet. Begin your timer.

   This is the bloom. Stirring at this stage ensures uniform saturation and prevents dry pockets that would cause uneven extraction.

4. 0:30

   Pour in slow circles to bring the total water in the dripper to 90 g.

5. 1:00

   Pour in slow circles to bring the total to 135 g.

6. 1:30

   Pour in slow circles to bring the total to 180 g.

7. 2:00

   Pour in slow circles to bring the total to 225 g. This is the fifth and final pour.

   All five pours of 45 g are now complete. The brew ratio at this stage is 1:15.

8. 2:30–3:00

   Once the dripper has fully drained, remove it. Add 45–60 g of additional water to the concentrate (bypass dilution), stir well, and pour into a serving cup.

   The brewed concentrate will taste strong on its own — this is intentional. Add more bypass water for a lighter and more delicate cup; add less for a stronger and more intense one.

   Expert tipSeparating extraction from final strength lets you draw out the coffee's full flavor potential first, then adjust concentration afterward without altering what was extracted.

9. 0:00 — ICED RECIPE

   Rinse the filter, add 15 g of coffee ground coarser than for the hot recipe, level the bed, and fill the server with ice. Begin your timer.

   Iced grind: EK43 at 10.5 (8 o'clock), Comandante 24–27 clicks, approximately 900–1,000 microns.

10. 0:00

    Pour 40 g of water evenly over the grounds to saturate all the coffee particles.

    Uniform saturation at this first pour is critical for even extraction and for fully awakening the coffee's aroma.

11. 0:30

    Pour 40 g of water in circles to reach 80 g total.

12. 1:00

    Pour 40 g of water in circles to reach 120 g total.

13. 1:30

    Pour 40 g of water in circles to reach 160 g total. This is the fourth and final pour.

    15 g of coffee to 160 g of water gives an extraction ratio of approximately 1:10.7.

14. 2:00–2:30

    Once the dripper has fully drained, remove it. Pour the brewed coffee over the ice-filled server to chill it rapidly, then transfer to an ice-filled glass and serve.

Why this works

Brewing at a 1:15 ratio with five evenly spaced pours pushes extraction upward, drawing out the full flavor and aromatic potential of the beans before any dilution. The bypass step then separates strength from extraction, so the final cup can be adjusted to taste without undoing what was already extracted. For the iced version, the coarser grind and tighter 1:10.7 brew ratio are calibrated to deliver body and aroma intact even as the coffee is chilled rapidly over ice. Stirring the grounds during the bloom at the start of both recipes eliminates dry pockets that would otherwise contribute to uneven extraction across the bed.

Where beginners go wrong

1. 1

   Concentrate tastes harsh straight from the dripper

   This is by design — the recipe brews a strong concentrate intentionally. Add the recommended 45–60 g of bypass water and stir before tasting.

2. 2

   Filter shifts or coffee runs down the sides of the dripper

   Use more water during the rinsing step and confirm the filter is pressed flush against all walls of the dripper before adding any grounds.

3. 3

   Iced cup tastes thin or the aroma is muted

   Confirm you are using the coarser iced grind (Comandante 24–27 clicks, approximately 900–1,000 microns) rather than the hot recipe setting. The iced ratio and grind are chosen specifically to preserve body and fragrance at lower temperatures.

4. 4

   Dry clumps remain after the bloom pour

   Stir the bed immediately after the first pour — 45 g for the hot recipe, 40 g for the iced — to make sure every particle is wet before subsequent pours begin.

What you should taste

A clean, well-extracted cup with a controlled final strength. The bypass dilution opens the aromatics and makes the flavors more expressive. The iced version retains aroma and body without tasting thin. When brewed with COE washed Geisha lots, expect clean, bright acidity alongside vivid, clear fruit sweetness.
