Pour-Over Coffee Ratios and Technique

Pour-over coffee looks like a ritual. Someone in a well-lit kitchen, a gooseneck kettle in hand, water spiraling over a cone of grounds, a timer on the counter. It looks like it requires a monk’s patience and a chemist’s precision.

It does not. It requires a scale, a kettle, a dripper, a filter, some coffee, and about four minutes. The ritual is optional. The ratio is not.

The short answer

Use 1 gram of coffee for every 16 grams of water. Grind medium-fine (table salt). Heat the water to about 200 to 205 degrees Fahrenheit (93 to 96 degrees Celsius). Pour slowly. Aim for a total brew time of three and a half to four and a half minutes. Taste it. Adjust one thing.

What you need

• A pour-over dripper. A Hario V60, a Kalita Wave, a Melitta, or any cone or flat-bottom dripper. They all work. The V60 is more sensitive to technique; the Kalita Wave is more forgiving. Pick whichever one you have or can afford.
• Paper filters. Matched to your dripper. Rinse them with hot water before brewing to remove papery taste and preheat the dripper.
• A grinder. A burr grinder set to medium-fine. A hand grinder works well here and is less expensive than an electric.
• A scale. Grams. Pour-over by volume (scoops and measuring cups) is inconsistent because coffee density varies by roast and origin.
• A kettle. A gooseneck kettle is ideal because it lets you control the flow rate and aim the stream. A regular kettle works but makes the pour harder to control.
• A timer. Your phone is fine.

The recipe

This is a starting recipe for a single cup using a V60 or similar conical dripper. Adjust to your dripper’s quirks and your taste.

Dose and water

• Coffee: 15 grams
• Water: 240 grams (a 1:16 ratio)
• Grind: medium-fine, roughly the texture of table salt
• Water temperature: 200 to 205 degrees Fahrenheit (93 to 96 degrees Celsius) [2]

The pour

Step 1: Bloom (0:00 to 0:45). Pour about 30 to 45 grams of water over the grounds in a slow spiral from the center outward. The goal is to saturate all the coffee evenly. Fresh beans will bubble and expand as CO2 escapes. Wait 30 to 45 seconds. This is the bloom, and it matters because dry pockets of coffee will under-extract if you skip it [3].

Step 2: First main pour (0:45 to 1:30). Pour in slow, concentric circles from the center outward and back, staying away from the edges of the filter. Add water until the total weight reaches about 150 grams. The stream should be steady and thin, not a deluge. You are agitating the coffee bed gently, not blasting it.

Step 3: Second main pour (1:30 to 2:30). Continue pouring in the same pattern until you reach 240 grams total. Keep the water level in the dripper relatively consistent. Do not let it drain completely between pours if you can help it, because an exposed coffee bed cools down and extracts unevenly.

Step 4: Drawdown (2:30 to 4:00). Stop pouring and let the water drain through. The total time from the first pour to the last drip should be roughly three and a half to four and a half minutes. If it finishes much faster, the grind is too coarse. If it is still dripping at five minutes, the grind is too fine.

Give the dripper a gentle swirl after you finish pouring. This settles the coffee bed flat and promotes even extraction. Then wait.

Reading the cup

Once the drawdown is complete, taste the coffee. Here is what the taste tells you:

• Sour, sharp, thin, tea-like: under-extracted. The water moved through too fast or did not extract enough. Grind finer, pour more slowly, or raise the water temperature.
• Bitter, dry, heavy, hollow: over-extracted. Too much contact time or too much agitation. Grind coarser, pour faster, or lower the water temperature.
• Sweet, balanced, clear flavors: you are there. Write it down.

As with espresso, change one variable at a time. If you grind finer and pour slower simultaneously, you will not know which adjustment helped.

Ratio variations

The 1:16 ratio is a middle ground. Here is how shifting it changes the cup:

Ratio	Coffee	Water	Character
1:14	15 g	210 g	Strong, intense, heavy body
1:15	15 g	225 g	Full-bodied, defined flavors
1:16	15 g	240 g	Balanced, the standard starting point
1:17	15 g	255 g	Lighter, more delicate, tea-like clarity

The SCA’s Golden Cup standard suggests a brewing ratio of roughly 55 grams of coffee per liter of water, which works out to about 1:18 [1]. That is a lighter cup than most specialty pour-over recipes aim for. Start at 1:16 and adjust to your taste.

The grind matters most

Pour-over is more forgiving than espresso, but grind quality still drives the result. An inconsistent grind (a mix of fine powder and coarse chunks) means the fines over-extract while the chunks under-extract, and the cup tastes muddled. A burr grinder produces a more uniform particle size than a blade grinder, and the difference shows up in the cup as clarity and sweetness.

You do not need an expensive grinder for pour-over. A hand grinder in the $30 to $60 range (Timemore C2, Hario Skerton Pro) produces a very capable pour-over grind. The tolerance for grind variation is wider than espresso, so the grinder budget can be lower.

Water temperature

Water temperature affects extraction speed. Hotter water extracts faster. The SCA recommends a brewing temperature of 195 to 205 degrees Fahrenheit (90.5 to 96 degrees Celsius) for optimal extraction [2].

A practical shortcut: boil the kettle and wait 30 to 60 seconds. That usually drops the temperature to roughly the right range. If you have a variable-temperature kettle, set it to 205 degrees Fahrenheit and adjust from there based on taste.

For lighter roasts, use the higher end of the range (205 degrees Fahrenheit). Light roasts are denser and harder to extract, so they benefit from hotter water. For darker roasts, try the lower end (195 to 200 degrees Fahrenheit), because dark roasts extract more easily and hotter water can push them into bitterness.

Common mistakes

Pouring too fast. A hard, fast pour agitates the coffee bed and pushes fines to the bottom of the filter, which can clog it and cause an uneven, over-extracted brew. Pour slowly and steadily.

Pouring on the filter walls. Water that hits the paper filter runs down the side without touching the coffee. It dilutes the brew without extracting anything. Keep your pour in the center and just off-center. Leave the outer edge alone.

Skipping the bloom. Fresh beans contain CO2 that repels water. If you pour all the water at once, the gas creates bubbles in the coffee bed that block extraction. The bloom lets the gas escape so the main pour can work evenly [3].

Eyeballing the dose. One rounded tablespoon of a light-roast Ethiopian and one rounded tablespoon of a dark-roast Sumatra weigh different amounts. Use a scale. It takes three seconds and removes the biggest source of inconsistency.

Blaming the dripper. A V60, a Kalita Wave and a Melitta all produce good coffee. The differences between them are real but smaller than the differences caused by grind size, water temperature and pouring technique. Switching drippers is rarely the fix. Adjusting the recipe usually is.

If you are coming from espresso

Pour-over uses a much coarser grind, much more water relative to coffee, and a much longer contact time than espresso. The result is a lighter, cleaner cup that highlights a bean’s origin flavors rather than the roast character. Many people find that pour-over shows them what their beans actually taste like, because there is less going on to mask it.

If your pour-over tastes flat or boring, the beans may be the issue. Pour-over rewards lighter roasts and single-origin coffees more than espresso does, because the brew method has the transparency to show their distinct flavors. A dark-roast blend designed for espresso will make a perfectly fine pour-over, but it will not showcase the method’s strengths.

Caffeine, heat and your machine. The FDA says up to about 400 mg of caffeine a day is not generally associated with negative effects for most healthy adults; pregnancy, some heart conditions, anxiety, reflux and certain medicines can change that, so check with a clinician if any apply. Steam wands and group heads are hot enough to burn. Unplug and cool a machine before opening or cleaning it, and follow the manufacturer’s descaling instructions.
