Pour schedule
Got the timing right? Make sure the grind is too.
Wrong grind size is the most common reason a perfectly-timed brew tastes off.
The gear that actually matters for timing
Coffee scale with built-in timer
Acaia Pearl S is the gold standard. Cheaper options like the Hario V60 Drip Scale or Timemore Black Mirror work great too — what matters is having both weight and time on one display.
See top scales →Variable-temp gooseneck kettle
Pour speed and direction matter as much as the schedule itself. The Fellow Stagg EKG is the popular pick; the Bonavita is the budget option.
See gooseneck kettles →Hario V60 02 (ceramic)
The most-used pour-over dripper in specialty cafés. Ceramic holds heat better than plastic, helping maintain temp through the whole brew.
See V60 options →AeroPress with metal filter
The original brewer is unbeatable for value. Pair with a reusable metal filter (like the Able DISK) for fewer paper filters and a slightly heavier body.

What's a bloom and why does it come first?
The bloom is the first 30–45 seconds of pour-over brewing, where you saturate the grounds with about 2× their weight in water and wait. As soon as hot water hits fresh coffee, dissolved CO₂ starts escaping rapidly — you'll see the coffee bed swell and bubble.
If you skip the bloom, that escaping gas pushes water away from the grounds during your main pour, creating uneven extraction. Some grounds get fully saturated, others barely contact water at all — which means a sour, weak, unbalanced cup.
The bloom uses about 2× the coffee weight in water (so 20g coffee → 40g bloom water). Wait until visible bubbling stops — usually 30–45 seconds. Fresher coffee blooms more aggressively.
Why split the pour into pulses?
For pour-over, splitting the main pour into multiple pulses keeps the brew bed agitated and water in steady contact with all the grounds. A single continuous pour creates uneven flow paths through the bed, leading to channeling and patchy extraction.
Most pour-over recipes use 3–4 pulses after the bloom, with each pulse adding roughly equal water amounts. Pour in slow, controlled circles starting from the center, working outward, then back to center.
Chemex specifically benefits from continuous slow pour rather than pulses, because its thick filter restricts flow naturally and the brew bed needs constant water to stay saturated.
What if my brew is finishing too fast or slow?
Too fast (under 2:30 for a single cup): Grind is too coarse OR your pour is too aggressive. First fix the grind — go 2–3 clicks finer. If grind is correct, slow your pour rate so water doesn't blast through.
Too slow (over 4:30 for a single cup): Grind is too fine, creating a clogged bed. Go 2–3 clicks coarser. Channeling can also slow drainage — make sure you're saturating evenly.
The schedule above assumes a properly-tuned grind. If your timing is off but everything else looks right, the grind is almost always the cause. Use the grind calculator to dial it in.
French press: why exactly 4 minutes?
4 minutes is the SCA-recommended steep time for full immersion brewing with a coarse grind. Shorter steeps under-extract (sour, thin), longer steeps over-extract (bitter, harsh).
The exception is James Hoffmann's French press technique, which uses a longer 9-minute total brew with a stir at 4 minutes and a long settling phase. That method produces a noticeably cleaner cup, but it's slower than most people want for a daily brew.
After plunging, pour everything out immediately. Coffee left in contact with grounds keeps extracting and turns bitter fast.
