Grind Setting and Steep Time Dynamics
-
Coarser Grind:
-
Larger particles slow extraction.
-
Requires longer steep times to reach balanced yield.
-
Risk: short steeps taste weak, under-extracted (sour, grassy).
-
Finer Grind:
-
Smaller particles increase surface area and extraction speed.
-
Requires shorter steep times to avoid over-extraction.
-
Risk: long steeps taste harsh, bitter, astringent.
-
Balancing Both:
-
Grind and time must be tuned together.
-
Example: French press with coarse grind → ~4–5 min steep.
-
AeroPress with medium-fine grind → ~1–2 min steep.
-
Cupping with medium-coarse grind → ~4 min steep.
-
Flavor Outcomes:
-
Coarse + long → round, heavy body, smooth finish.
-
Fine + short → bright, clear, and expressive.
-
Mismatch (fine + long or coarse + short) → poor balance, either bitter or sour.
-
Practical Tips:
-
Adjust steep time in 15–30 second increments when dialing in.
-
Keep brew ratio constant to isolate grind/time effects.
-
Taste side by side to train palate on under- vs over-extraction cues.
Summary
Grind setting and steep time are interdependent levers in immersion brewing. Coarser grinds need longer contact, finer grinds shorter, and balancing the two is key to achieving a sweet, balanced cup.
