Quick Answer

Use 20 g coffee and 320 g brew water for a 1:16 starting ratio. Grind medium-fine to medium and begin near 93 C / 200 F. Bloom to 50 g until 0:40, pour to 180 g, then finish at 320 g. A total time around 2:45-3:45 is a useful observation window for this recipe, not a universal target. Taste the cooled coffee before adjusting one variable.

Key Takeaways

  • 1The measured starting recipe is 20 g coffee to 320 g brew water.
  • 2Bloom to 50 g, then use two calm main pours to reach 320 g.
  • 3Brew water is an input; the cup will weigh less because grounds and filter retain water.
  • 4Use time and drawdown as clues, then let taste decide the next adjustment.

Before You Brew

This recipe is a practical home baseline, not a universal cafe standard. Dripper geometry, filter, grinder, coffee, water, batch size, and pouring style all affect flow. Keep the recipe stable for the first brew so the result gives you useful feedback.

Use freshly ground coffee and water that tastes good on its own. Start around 93 C / 200 F; a working range of roughly 90-96 C / 194-205 F leaves room for different coffees and roast levels. Temperature alone does not determine whether a cup will taste sour or bitter.

Equipment

  • Manual filter dripper and compatible filter
  • Mug or server large enough for the finished brew
  • Burr grinder
  • Digital scale accurate to at least 1 g
  • Kettle; a gooseneck makes controlled pouring easier
  • Timer
  • Spoon or stirrer

The pour over setup guide explains compatibility and upgrade priorities if you are choosing equipment.

Step-by-Step Method

  1. Prepare the brewer. Place a compatible filter in the dripper, rinse it thoroughly, discard the rinse water, and set the dripper and server on a scale.
  2. Weigh and grind. Grind 20 g of coffee medium-fine to medium. Add it to the filter, level the bed, and tare the scale.
  3. Bloom to 50 g. Start the timer and wet all the coffee until the scale reads 50 g. Gently swirl only if dry pockets remain, then wait until 0:40.
  4. Pour to 180 g. Add water in a calm, controlled pour until the scale reads 180 g. Keep the stream mostly over the coffee bed rather than pouring continuously onto the filter wall.
  5. Pour to 320 g. Continue or resume pouring until the total brew-water weight reaches 320 g.
  6. Let the brew finish. Allow the remaining water to drain. Record the total time and what the drawdown looked like; do not force the brewer to match a number by adding unnecessary agitation.
  7. Serve and evaluate. Remove the dripper, swirl the server, and let the coffee cool slightly. Taste the whole cup before changing one variable for the next brew.

The Coffee Bloom Guide explains bloom water, degassing, and even wetting without treating bubbles as a pass/fail freshness test.

Reading Brew Time and Drawdown

For this 20 g recipe, 2:45-3:45 is a useful observation window. A brew outside it is not automatically wrong. Different filters, drippers, grinders, and coffees can produce good cups at different times.

If the brew drains much faster or slower than your own normal result, first check for a changed grind setting, filter fit, dose, pouring pattern, or unusual clogging. The dedicated fast-draining pour over guide covers that symptom in more detail.

Adjusting by Taste

Hold dose and brew water constant, then make one small change. Taste descriptors are evidence, not automatic diagnoses, so use the complete pattern rather than one word alone.

Coffee Reference Table
Coffee Reference Table
What you noticeA useful first experiment
Sharp, thin, or unfinishedGrind slightly finer, or improve even saturation
Heavy, drying, or harshGrind slightly coarser, or reduce unnecessary agitation
Balanced but too strongKeep technique stable and move toward a longer ratio
Balanced but too lightKeep technique stable and move toward a shorter ratio
Uneven mix of sharp and drying sensationsImprove distribution and pouring consistency before chasing ratio

The pour over ratio calculator is the better tool when the cup is balanced but the strength is wrong. For broader diagnosis, see coffee extraction, grind size, and brewing temperature.

Adapting the Recipe

Without a Gooseneck Kettle

Use a kettle with a manageable spout and pour in smaller, calm additions. A spoon or other diffuser can soften an aggressive stream. Avoid trying to imitate intricate patterns that the kettle cannot control.

For a Larger Batch

Scale coffee and brew water with the same ratio, then expect bed depth and drawdown to change. Do not assume a doubled batch will behave exactly like the 20 g recipe. Use the ratio guide for the calculation.

For a Different Dripper

Keep 20 g and 320 g as the first comparison point, but use the manufacturer's filter and capacity guidance. Grind and pouring may need adjustment because geometry and flow restriction differ.

Common Recipe Mistakes

Coffee Reference Table
Coffee Reference Table
MistakeWhy it causes trouble
Changing dose, grind, temperature, and pouring togetherYou cannot tell which change affected the cup
Using milliliters for coffee doseCoffee dose and finished beverage should be measured by mass for repeatability
Calling brew water the final yieldThe bed and filter retain water
Treating total time as a quality scoreTime records the system; taste evaluates the result
Pouring hard to force a specific drawdownExtra agitation can move fines and change flow

Bottom Line

Begin with 20 g coffee, 320 g brew water, a 50 g bloom, and two calm main pours. Record what happens, taste after the coffee cools slightly, and adjust one variable. The goal is not to obey a universal stopwatch number; it is to create a repeatable brew that you can improve deliberately.

Recipe Questions

How much coffee do I use for one pour over?
This recipe uses 20 g coffee and 320 g brew water for one large cup or two smaller cups. Use the ratio calculator when changing batch size.
How much water should I use for the bloom?
Use 50 g for the 20 g dose, enough to wet the bed thoroughly, and wait until 0:40 before the main pour.
Should I stir or swirl the bloom?
A gentle swirl can help when dry pockets remain, but it is optional. Keep agitation modest and repeatable.
What temperature should I use?
Start near 93 C / 200 F. The practical 90-96 C / 194-205 F range allows adjustments for the coffee and result.
How long should this pour over take?
The 20 g recipe often falls around 2:45-3:45, but the time is an observation window, not a universal target.
Can I make this without a scale?
You can brew without one, but a scale is the simplest way to repeat dose, bloom, and total brew water accurately.
