How to Make Pour-Over Coffee: Ratio, Grind, Bloom & Pouring (2026)

Pour-over coffee is not one recipe.

A Hario V60, Kalita Wave and other filtered drippers can all make excellent coffee while using different:

• coffee-to-water ratios;
• bloom doses;
• grind settings;
• pour structures;
• drawdown times.

That is why the safest way to learn pour-over is to start from a documented recipe for the brewer you own, then change one variable at a time.

Cafe & Crema’s assessment is based on current Hario and Kalita brewing guidance, current brewer/filter documentation, and our analysis of how those recipes translate into a repeatable home workflow. Cafe & Crema has not performed first-party comparative pour-over testing for this guide.

The short version

For a normal manual pour-over:

1. use fresh coffee and a suitable paper filter;
2. weigh coffee and water;
3. start from a documented recipe for your dripper;
4. use a medium or medium-fine grind as the recipe specifies;
5. pre-wet the filter when the brewer/filter instructions call for it;
6. bloom for the documented time;
7. pour the rest of the water in the pattern the recipe expects;
8. use drawdown time as a recipe-specific reference;
9. taste;
10. change one variable at a time.

The important phrase is recipe-specific reference.

A 3:00 drawdown can be normal for one recipe and wrong for another.

Three current pour-over recipe references

Current manufacturer and industry recipes make the variation obvious.

Hario one-cup V60 reference

Hario USA currently publishes James Hoffmann’s one-cup V60 technique with:

• 15 g coffee
• 250 g water
• medium-fine grind
• freshly boiled soft, filtered water for lighter roasts
• 50 g bloom
• 45-second bloom
• multiple controlled pours
• drawdown finishing around 3:00

That ratio is about 1:16.7.

Hario also explicitly says to expect some variance in drawdown and that taste is the most important result.

Hario larger V60 reference

Hario also publishes Hoffmann’s larger V60 technique with:

• 30 g coffee
• 500 mL water
• medium-fine grind
• 60 g bloom
• bloom up to 45 seconds
• staged pours
• drawdown finishing around 3:30

Same brewer family, larger recipe, different timing reference.

Kalita Wave reference

Kalita’s current Wave method recommends:

• staying around 1:16–1:18
• roughly 60 g bloom water in its example
• 30–45 seconds of bloom
• remaining water added in increments
• approximately 2–3 minutes total brew time

That is a different brewer architecture and a different recipe window.

The conclusion is not that one is correct and another is wrong.

It is that pour-over timing must be interpreted inside the recipe you are actually using.

Coffee-to-water ratio

The old version of this page told readers to start at exactly 1:16.

That is too narrow.

Current examples span roughly:

• Hario: about 1:16.7
• Kalita: 1:16–1:18

That gives a more useful practical starting range.

What ratio changes

Changing ratio changes beverage strength and also changes the brewing system because it changes:

• how much water passes through the bed;
• total contact time;
• slurry depth;
• thermal behavior.

So do not think of ratio as an isolated strength dial.

If you change from 1:16 to 1:18, keep everything else as stable as possible and taste the result before changing grind too.

A coffee scale is the easiest way to make this repeatable.

Grind size

“Medium” and “medium-fine” are only starting descriptions.

They are not transferable numeric settings.

The same dial number can mean completely different burr gaps on different grinders.

Current Hario recipes use medium-fine in several V60 methods.

Kalita’s current Wave guidance also starts from a pour-over-appropriate grind and tells users to adjust if the cup tastes wrong.

The correct workflow is:

1. choose the documented recipe;
2. start with the recipe’s grind description;
3. record the setting on your grinder;
4. compare drawdown and taste;
5. change one step or one small increment at a time.

For the mechanics behind adjustment, use burr grinders explained.

Drawdown time is a diagnostic signal, not the target itself

The old guide said time was the target and recommended three to four minutes for a cone.

Current recipes show why that is too absolute.

Examples:

• Hario one-cup V60: around 3:00
• Hario larger 30 g / 500 mL V60: around 3:30
• Kalita Wave guide: around 2–3 minutes

Time is still useful.

If a recipe that normally finishes near 3:00 suddenly takes 5:00 with the same coffee and dose, something changed.

Possible causes include:

• finer grind;
• more fines;
• different filter paper;
• higher dose;
• stronger agitation;
• stalled flow.

But hitting one stopwatch number does not prove the brew is good.

Hario’s current guidance is explicit that taste remains the important result.

Bloom

A bloom is the initial wetting phase before the main brew.

Current recipes use different bloom doses and times.

Examples:

• Hario one-cup V60: 50 g on 15 g coffee, 45 seconds
• Hario larger V60: 60 g on 30 g coffee, up to 45 seconds
• Kalita Wave: about 60 g, 30–45 seconds

So the useful rule is not “always use exactly twice the coffee weight.”

The useful rule is:

Use the bloom structure designed for the recipe, make sure the coffee bed is wetted, then move into the main pours.

Is blooming mandatory?

Many current pour-over recipes include it.

That does not mean every filtered brewer or every hybrid recipe must use the same bloom.

Hario’s Switch and other immersion/hybrid brewers can use different sequences because the valve changes how water and coffee interact.

If you want less dependence on manual pulse timing, compare best immersion and hybrid brewers.

Pour pattern

The old page gave one universal instruction:

center → spiral outward → avoid the paper wall.

That is too prescriptive.

Current Hario recipes use different pour structures.

Hario’s larger Hoffmann recipe explicitly says not to worry about pouring directly onto the V60 filter in that method.

Other recipes use concentric circles or staged pulses.

The better rule is:

1. follow the pour pattern documented for the recipe;
2. keep the stream controlled;
3. wet the intended coffee bed evenly;
4. avoid changing pour height, pulse size and agitation all at once.

Pour pattern matters because it changes where and how much energy/water reaches the bed.

It should not be separated from the recipe.

Do you need a gooseneck kettle?

A gooseneck makes manual pour rate and placement easier to control.

That matters most when the recipe depends on:

• precise pulses;
• slow controlled pours;
• repeatable stream placement.

It matters less for full-immersion brewing, where the brewer holds the entire slurry before release.

If pour control is the bottleneck, use best gooseneck kettles.

Filter preparation

Kalita’s current filter guidance says to pre-wet its Wave filters before brewing.

Hario recipes also commonly include rinsing/preheating steps.

Pre-wetting can:

• seat the paper;
• warm the brewer/server;
• rinse loose paper residue.

Do not turn that into a universal claim that every modern paper filter creates a strong paper taste unless rinsed.

Follow the exact filter/dripper instructions.

Water temperature

There is no single temperature that every valid pour-over recipe uses.

Examples:

Hario one-cup V60

Current Hario-hosted Hoffmann guidance uses freshly boiled soft, filtered water for lighter roasts.

Hario Alpha recipe

Hario’s current Alpha recipe gives around 90°C as one starting point.

Those current Hario examples are both legitimate documented starting points.

So rather than saying “92–96°C covers everything,” keep temperature stable while dialing a recipe and move it deliberately when needed.

Sour, bitter and harsh are not one-word diagnoses

The old guide reduced:

• sour = under-extracted;
• bitter = over-extracted.

Those labels can be useful shorthand, but they are not sufficient on their own.

Taste also depends on:

• coffee origin;
• roast;
• water;
• grind distribution;
• brew ratio;
• temperature;
• channeling;
• agitation;
• filter.

If the cup tastes sharp or thin

Check:

• did the brew run much faster than the recipe normally does?
• did the grind change?
• was all the coffee wetted?
• did the water cool unexpectedly?
• is the ratio the same?

Then change one variable.

If the cup tastes harsh, dry or bitter

Check:

• did drawdown slow dramatically?
• is the grind much finer?
• did agitation increase?
• did the filter clog?
• is the coffee itself darker or more bitter by roast character?

Again, change one variable.

Cone vs flat-bottom matters

A Hario V60 and Kalita Wave do not have the same geometry.

The V60 uses:

• 60° cone;
• spiral ribs;
• single large opening.

The Wave 185 uses:

• flat bottom;
• three small extraction holes;
• 20-wave filter.

Those differences affect flow.

That is why copying one brewer’s recipe into the other is not a controlled comparison.

For the architecture decision, use flat-bottom vs cone pour-over drippers.

For current buying choices, use best pour-over drippers.

A repeatable home workflow

Use this when learning a new coffee.

1. Pick one recipe

Do not combine the ratio from one source with the pour structure from another on the first brew.

2. Weigh coffee and water

Record the exact numbers.

3. Use the documented grind starting point

Do not borrow a grinder dial number from another grinder.

4. Keep water temperature stable

Use the recipe’s recommendation.

5. Execute the bloom and pours as written

That gives you a baseline.

6. Record drawdown

Treat it as a diagnostic reference.

7. Taste

Taste decides whether the recipe is worth keeping.

8. Change one variable

Grind is usually the easiest variable to adjust in small increments.

What to buy first

Do not use a universal gear ranking.

Buy around the bottleneck.

Your grind is inconsistent

Prioritize the grinder.

See burr grinders explained and best coffee grinders.

You cannot repeat the ratio

Use a coffee scale.

You struggle to control pulse pouring

Use a gooseneck kettle.

You are choosing the brewer itself

Use best pour-over drippers and the flat-bottom vs cone comparison.

You want less manual pouring

Use best immersion and hybrid brewers.

Frequently asked questions

What coffee-to-water ratio should I use for pour-over?

Use the recipe for the brewer you own as the first baseline. Current Hario examples include 15 g coffee with 250 g water and 30 g with 500 mL, both about 1:16.7. Kalita currently recommends staying around 1:16–1:18 in its Wave brewing guidance. Those are useful reference points, not a universal law.

How fine should I grind for pour-over?

Medium to medium-fine is a common starting description in current Hario and Kalita recipes, but the exact setting depends on the dripper, filter, dose, grinder and recipe. Do not copy a dial number from another grinder. Adjust from the documented recipe while keeping ratio and pouring method stable.

How long should pour-over coffee take?

There is no single correct drawdown time across all pour-over brewers. Hario's current one-cup V60 recipe aims to finish around 3:00, its larger 30 g / 500 mL Hoffmann recipe around 3:30, and Kalita's current Wave method gives roughly 2–3 minutes. Treat time as a recipe-specific reference and diagnostic signal, not a universal target.

How long should I bloom pour-over coffee?

Current recipes commonly use about 30–45 seconds. Hario's current one-cup V60 technique uses a 45-second bloom, while Kalita's current Wave guide recommends about 30–45 seconds. The purpose is to wet the bed before the main pours; exact bloom dose and time remain recipe-specific.

What temperature should I use for pour-over coffee?

Use the brewer/recipe guidance rather than one fixed number for every coffee. Hario's current one-cup V60 recipe uses freshly boiled soft filtered water for lighter roasts, while Hario's Alpha recipe gives around 90°C as one starting point. Those examples already show that valid recipes can differ.

Why does my pour-over taste sour?

Do not treat sourness as proof of one single fault. A fast or weak extraction can contribute, but roast character, water, grind distribution, ratio, temperature, channeling and recipe all matter. Compare the cup with drawdown behavior and change one variable at a time.

Why does my pour-over taste bitter or harsh?

Bitterness or harshness can coincide with a slow or overly fine brew, but taste alone does not diagnose the cause. Check whether the recipe ran very differently from its normal drawdown, then adjust grind or another single variable while keeping the rest stable.

Do I need a gooseneck kettle for pour-over?

A gooseneck kettle makes pour rate and placement easier to control in recipes that depend on manual pulses. It is useful, not mandatory for every filtered-coffee method. Immersion and hybrid brewers reduce how much the result depends on continuous manual pouring.
