Easy pour over with a flat-bottom dripper

A forgiving brewer: bloom, then a few small pulse pours to 240 g.

⏱️ 8 minEasy

Starting recipe

15 g coffee + 240 g water at 93 °C (199 °F) in a bloom plus 4 pulse pours, total time 2:30–4:00.

Grind: Medium-fine, like table salt

You need

  • 15 g fresh coffee, ground medium-fine (like table salt)
  • A flat-bottom dripper and its matching flat or wave filter
  • A kettle (gooseneck if you have one)
  • A kitchen scale and a timer
  • A mug or small carafe

Step by step

  1. Heat water and grind

    Boil water and let it rest about 30 seconds so it's near 93 °C. Grind 15 g of coffee medium-fine, like table salt.

  2. Rinse the filter

    Set the filter in the dripper and pour hot water through to rinse and preheat. Wave-style filters crumple easily, so pour into the center, not on the ridges. Throw away the rinse water.

  3. Add coffee and level

    Add the grounds, shake gently to make a flat bed, set everything on the scale and tare to zero.

  4. Bloom

    Start the timer and pour 40 g of water so all the grounds are wet. Wait while it bubbles.

    40 s
  5. Pulse pours

    Pour about 50 g at a time in slow circles in the middle: to 90 g, 140 g, 190 g and finally 240 g. Pour each one when the water level has dropped a bit, roughly every 20–25 seconds. Finish pouring by about 2:00.

  6. Let it drain

    A flat bed drains evenly. Drawdown should be done between 2:30 and 4:00 on your timer.

    60 s
  7. Taste and adjust

    Swirl, sip, and let it cool a bit. Sour? Grind finer. Bitter? Grind coarser. One change at a time.

Common mistakes

  • Pouring onto the filter ridges and flattening them, which lets water bypass the coffee.
  • Adding all the water at once so the brewer overflows.
  • Not leveling the bed, so one side extracts more than the other.
  • Changing more than one thing per brew.

Tastes off? Fix it

If it…Try this
Sour or thinGrind a little finer so the water spends more time with the coffee.
Bitter or dryGrind a little coarser.
WeakUse a bit more coffee for the same water, for example 16 g.
Too strongUse a bit less coffee for the same water, for example 14 g.
Drains fast (under 2:30)Grind finer and leave a little more time between pulses.
Drains slow (over 4:00)Grind coarser and pour more gently so you don't churn up fines.

Words you'll hear

Bloom
The first small pour that just wets the grounds. Fresh coffee puffs up and releases gas, which helps the rest of the water extract evenly.
Ratio
Water weight divided by coffee weight. 1:16 means 15 g of coffee to 240 g of water.
Extraction
How much flavor the water pulls from the grounds. Under-extracted tastes sour and thin; over-extracted tastes bitter and dry.
Drawdown
The last stage, when you've stopped pouring and the water drains through the coffee bed. It tells you how fine your grind is.
Bed
The layer of grounds in the filter. A flat bed after drawdown means the water flowed evenly.
Pulse pour
Pouring in several small portions with short pauses, instead of one long continuous pour.
Gooseneck kettle
A kettle with a thin curved spout that gives you a slow, precise stream. Helpful, but a normal kettle poured carefully works too.
Fines
Tiny dust-like particles from grinding. Lots of them can clog the filter and slow the drawdown.
