7 Steps to Pour-Over Perfection

Making coffee is chemistry. It is physics. It is the only reason many of us are functional before 9:00 AM.

But there is a vast canyon between "hot bean water" and a truly excellent cup of pour-over. You do not need a degree in fluid dynamics to cross that canyon. You just need a system.

Here is how you turn your morning ritual into a repeatable science experiment where the result is always delicious.

Step 1: Respect the Gear

You cannot chop vegetables with a spoon. You cannot make consistent coffee with a blade grinder. Blade grinders smash beans into random boulders and dust. That dust over-extracts and tastes bitter. The boulders under-extract and taste sour.

Get a burr grinder. It is the single most important tool on your counter. A consistent grind size is the foundation of everything that follows. If you change nothing else, change this.

Step 2: The Golden Ratio

Eyeballing it is for amateurs. Use a scale.

The industry standard for a balanced cup is a 1:16 ratio. That means for every 1 gram of coffee, you use 16 grams of water.

Want it stronger? Go 1:15. Lighter? Try 1:17.

For a standard single mug, start with 20 grams of coffee and 320 grams of water. This removes the guesswork. You will never again wonder why today’s cup tastes like mud while yesterday’s tasted like nectar.

Step 3: The Grind Size

Pour-over requires a medium-coarse grind. Think Kosher salt or sea salt.

If the water pools at the top and refuses to drain, your grind is too fine. If the water rushes through in two minutes flat, your grind is too coarse.

You want the water to encounter resistance, but not a wall. It should take about three to four minutes for the water to pass through the grounds. Adjust your grinder until you hit that window.

Step 4: Temperature Control

Boiling water burns coffee. It scorches the grounds and pulls out astringent, ash-like flavors.

Your target range is 195°F to 205°F (90°C to 96°C).

If you do not have a temperature-controlled kettle, boil your water and then open the lid. Wait 30 to 60 seconds. This drops the temperature right into the sweet spot. Darker roasts prefer the cooler end of that spectrum (195°F), while lighter roasts open up better with more heat (205°F).

Step 5: The Bloom

Fresh coffee has gas. Literally. Roasting traps carbon dioxide inside the bean. If you pour all your water at once, that gas repels the water. Your coffee will be weak.

You must degas the grounds. Pour just enough water to wet the coffee—about 40 to 60 grams. You will see the bed rise and bubble. This is the bloom.

Wait 30 to 45 seconds. Let the gas escape. Once the bubbling stops, the grounds are ready to accept water and release flavor.

Step 6: The Pour

Do not dump the water. Pour it.

Start in the center. Move in a slow, steady spiral toward the edge, but do not touch the paper filter. Pouring down the side allows water to bypass the coffee entirely.

Keep the water level consistent. You want a flat bed of coffee at the end, not a crater. A flat bed means every crumb of coffee received the same amount of water. Consistency equals flavor.

Step 7: The Diagnosis

This is where you become the expert. You taste the coffee. It might not be perfect yet. That is okay. You can fix it.

Use your palate to troubleshoot. There are two main enemies: sourness and bitterness.

If it tastes sour, acidic, or salty:

The coffee is under-extracted. The water moved too fast or was not hot enough.

The Fix: Grind finer next time. This increases surface area and slows the water down. You can also try hotter water.

If it tastes bitter, dry, or hollow:

The coffee is over-extracted. You pulled too much out of the bean.

The Fix: Grind coarser. This speeds up the flow. Alternatively, lower your water temperature slightly.

Save your notes in Foodofile. Track which grind setting worked for which bean. You will build a personal library of perfect brews. Coffee is not luck. It is variables. Control them, and you control your morning.
