How to Brew Pour-Over Coffee with Filter Paper

If you’ve ever dismissed filter coffee as ‘just hot water poured over grounds’, you’re missing out—and probably making it wrong. What seems like the simplest brew method is deceptively technical. A poor pour, bad water temp, or uneven bloom can ruin even great beans. But when done right, it’s clean, bright, and revealing.

To brew a proper cup of filter coffee by hand, use 12–15 grams of medium-fine ground coffee per cup, pour water at around 92°C after a quick bloom at 93–96°C, and aim for a total brew volume of roughly 150–180 millilitres per cup using steady, circular pours. Consistent water flow and proper timing are essential.

What Is Filter Coffee—And Why It’s Not ‘Easy’

Filter coffee, often called ‘lazy coffee’ because it uses minimal gear, is frequently underestimated. Unlike espresso machines or siphon brewers, it doesn’t require complex tools—but that doesn’t mean it’s simple. In fact, its apparent ease is misleading. Without precision in grind size, water temperature, blooming, and pouring technique, the result can be dull or off-flavoured. Don’t expect great results from a careless brew.

Step-by-Step: How to Brew Filter Coffee the Right Way

1. Prepare the Filter

Start with a clean filter paper. Check for holes or damage, and discard damp sheets. Fold the filter along its seam—first in one direction, then the opposite—to form a cone. Open it fully and place it snugly into your dripper so it sits flat against the walls.

2. Add Ground Coffee

Use 12–15 grams of medium-fine coffee per cup (adjust grind to match your dripper—see our grind guide). Place the grounds in the filter, then gently tap the sides of the dripper with your palm to settle the coffee and create an even bed. Set the loaded dripper on top of your server or cup.

3. Heat and Measure Water

Use filtered water. For one cup, measure about 180–200 millilitres. Heat the water to a full boil (100°C), then let it cool slightly before brewing.

4. Preheat Everything

While waiting for the water to boil, pour a small amount of hot water into the server or cup, swirl to warm it, then discard the water. This preheats your equipment. Replace the coffee-filled dripper on the server after preheating.

5. First Temperature Drop & Bloom

Wrap a dry towel around your boiled kettle, dip it in cold water to moisten, and let it sit on the kettle for 20–30 seconds. This reduces the water temperature to around 92°C. Start the bloom by pouring just enough hot water—using a very fine, steady stream—to wet all the grounds. Pour in a spiral from the centre outward. Stop when the coffee is fully saturated but no more than five drips fall into the server. Let it bloom: the grounds will expand as they absorb water.

6. Second Temperature Drop

After the bloom, place the kettle back on the damp towel for another 20–30 seconds to lower the water temperature to approximately 85°C for the main brew.

7. Main Pour (Brew Phase)

Begin pouring from the centre of the coffee bed, moving in a steady, controlled spiral outward. Use a slightly wider stream than during the bloom, but keep it even and uninterrupted. Pour about 150–180 millilitres of water for one cup. Stop pouring once the water level reaches the edge of the filter. To finish, pour a small amount in the centre to draw down the last of the brew. The ideal final yield is just a bit more than the cup’s capacity—leaving a little for the brewer to taste.

The coffee bed should end up as a neat, oval-shaped dome on the filter paper.

Brewing Tips & Techniques That Make a Difference

Tip 1: Always Use Freshly Boiled Water

Always start with water that has just reached a boil. Avoid reboiling previously cooled water or using water from a thermos that’s been keeping it hot—it impacts extraction quality.

Tip 2: Why Cool the Water?

Cooling boiled water with a damp towel prevents the coffee grounds from being scalded by water that’s too hot, which can burn delicate aromatics and ruin flavour.

Tip 3: How to Know When Bloom Is Done

It’s hard to see if all the grounds are wet, especially as they swell quickly. Look for the moment when just a few drops (no more than five) begin to fall through the filter, and the coffee surface is evenly shiny: that’s when blooming is complete.

Tip 4: Stand While Pouring for Better Control

Sitting makes it hard to control the pour—your arm will be raised too high and you’ll rely only on your wrist. Instead, stand, lean slightly forward, hold the kettle with your right hand, rest your right elbow against your body, and use your left hand for balance. Move your upper body in a smooth pendulum motion, not just your arm, for even, stable pours.

Tip 5: Stable Flow Is Everything

The key to great filter coffee is consistent, even water flow. Uneven pouring leads to uneven extraction—some grounds over-extracted, others under—resulting in off-flavours or muddled cups. That’s why this ‘simple’ method is actually hard to master perfectly.

Frequently Asked Questions

What is the ideal water temperature for pour-over coffee?

The recommended brewing temperature is around 92°C, achieved by letting boiled water (100°C) cool for 20–30 seconds after wrapping the kettle in a damp towel. For the bloom, use slightly hotter water (~93–96°C).

How much coffee should I use per cup when brewing filter coffee?

Use 12–15 grams of medium-fine ground coffee per cup. Adjust based on your taste preference and dripper type, but this range is standard for balanced extraction.

What grind size is best for pour-over coffee?

The grind should be medium-fine—similar to table salt. The exact setting depends on your dripper, but it should allow for an extraction time of around 2–3 minutes with steady pouring.

How long should I let the coffee bloom?

The bloom phase should last about 30–45 seconds, just long enough for the coffee grounds to fully expand after being saturated with hot water. Stop pouring when only a few drops (no more than five) fall through.

Why should I preheat my pour-over equipment?

Preheating the server, dripper, and filter with hot water ensures that no heat is lost during brewing, helping maintain a stable extraction temperature for better flavour.

How much total water should I pour for one cup of coffee?

Aim for approximately 150–180 millilitres of brewed coffee per cup. The total pour should be slightly more to allow for a few extra millilitres you can taste directly from the dripper.
