A hand filter is quick to buy: a filter, paper, hot water, done. Nevertheless, the first cup often tastes different than expected. Sometimes sour and thin, sometimes bitter and heavy. This is rarely the fault of the device, but rather a few details: grind size, quantity, temperature, and how you pour the water.
In short: For a cup of hand-filtered coffee, I use 20 g of medium-ground coffee and 300 g of 93 °C water. First, I pour 60 g of water and let the coffee bloom briefly. Then, the rest of the water follows in four more pours, with the last one starting at 2:00 minutes. After about 2:45 to 3:15 minutes, the coffee has finished brewing. Taste and brew time together will show you whether you should grind finer or coarser.
What a hand filter is and why the coffee tastes so clear
With a hand filter, often called "pour over," you pour hot water by hand over ground coffee in a paper filter. The water extracts the aromas and runs through the paper into the cup or carafe. There is no pressure and no machine, only gravity and your hand.
The method has a German history: In 1908, Melitta Bentz from Dresden registered her coffee filter as a utility model with the Imperial Patent Office. She had previously experimented with blotting paper and a perforated brass cup to prepare coffee without grounds in the cup (DPMA).
The paper holds back a large portion of the coffee oils and fine particles. That is why hand-filtered coffee usually tastes clearer and lighter than coffee from a French press. This is exactly what makes it interesting for light roasts: fruit, floral notes, and acidity remain clearly recognizable.
What you need for coffee with a hand filter
- Hand filter (for example, cone or trapezoidal shape) and matching filter paper
- Coffee grinder, ideally with conical or flat burrs, to ensure the coffee grounds are uniform
- Kitchen scale with a timer or a scale plus a mobile phone stopwatch
- Kettle, ideally with temperature control and a narrow spout
- Cup or carafe on which the filter sits securely
Which material for the hand filter?
Plastic is lightweight, shatterproof, and good for travel. Look for heat-resistant, food-safe plastic. With frequent use, it can become discolored.
Metal is very robust and also suitable for travel.
Glass looks beautiful but is more prone to breakage.
Ceramic or porcelain is robust and hardly discolors thanks to the glazed surface. It absorbs heat at the beginning, so pre-rinsing with hot water is especially worthwhile here.
For the taste, the shape is usually more important than the material. Cone-shaped filters with a large opening usually let the water run through faster, so you control the flow more through your pouring technique. Trapezoidal filters with small holes, on the other hand, often slow the water down a bit. My recipe below was developed on a cone-shaped Hario V60. It serves as a starting point for a trapezoidal filter, but you may need to adjust the grind size slightly.
My hand filter recipe step by step
This is how I brew our light filter coffees like TIKI TAKA, PLAYMAKER, and WARM UP. I use a Hario V60 with matching V60 paper filters. With other hand filters, the recipe is a good starting point; grind size and brew time may shift slightly.
| Coffee | Grind size | Water | Temperature | Brew time |
|---|---|---|---|---|
| 20 g | medium (approx. 650 microns) | 300 g | 93 °C | 2:45–3:15 min. |
- Heat water to 93 °C.
- Place the filter paper in the hand filter and thoroughly rinse the filter, paper, and cup or carafe with hot water. Pour out the rinse water.
- Grind 20 g of coffee to a medium consistency, put it into the filter, and shake slightly so that the grounds lie flat. Tare the scale to zero.
- 0:00 – Pour 60 g of water so that all the coffee grounds are wet (bloom).
- 0:40 – Start the second pour until the scale shows 120 g in total.
- 1:00 – Start the third pour until a total of 180 g.
- 1:30 – Start the fourth pour until a total of 240 g.
- 2:00 – Start the final pour until a total of 300 g.
- Let it drain. With this recipe, the coffee is usually ready after 2:45 to 3:15 minutes.
The times indicate when a pour begins, and the amounts are total quantities on the scale. 300 g of water corresponds to approximately 300 ml. Pour slowly in small circles from the center outwards and avoid pouring directly onto the paper at the edges.
Variation for VERLÄNGERUNG
Not every coffee needs the same recipe. I brew our VERLÄNGERUNG from Brazil (strawberry, rum, ripe fruit) slightly cooler and coarser: 20 g of coffee at about 700 microns, 300 g of water at 92 °C. Pours begin at 0:00 (60 g), 0:45 (up to 130 g), 1:15 (up to 210 g), and 1:50 (up to 300 g). The brew time here is 3:00 to 3:30 minutes.
Correctly adjusting grind size, temperature, and water
Grind size: Medium is a good start; for me, that is about 650 microns. Which setting that corresponds to on your grinder depends on the model. The brew time in the recipe is a guideline, not a judgment: if the coffee tastes good, a few seconds more or less is not a mistake.
Temperature: I brew our light filter coffees at 92 to 93 °C. If your kettle doesn't show the temperature, let the boiling water sit briefly before pouring. How long depends on the kettle and the amount of water; a thermometer makes it more precise.
Water: In a hand filter, the cup consists almost entirely of water. In Munich, the tap water is hard, which can make light, fruity roasts taste duller. You can read about what is behind this and what you can do in our article Water for coffee in Munich.
Always change only one thing at a time when adjusting. Otherwise, you won't know in the end what made the difference.
Which beans suit the hand filter
The hand filter shows aromas very clearly, so light and medium-light roasts are particularly suitable:
- TIKI TAKA from Ethiopia with jasmine, bergamot, and peach: floral and light
- PLAYMAKER from Kenya with blackcurrant, red berries, and honey: fruity and juicy
- WARM UP from Costa Rica with tangerine, brown sugar, and citrus: sweet and balanced
You can also brew espresso roasts in a hand filter. They will then usually taste rounder and chocolatier, with the fruit taking more of a backseat.
Typical mistakes with the hand filter and what you can change
The coffee tastes sour or thin
Usually, it was under-extracted. Grind a bit finer. If the brew time is already in the target range, you can also increase the temperature slightly.
The coffee tastes bitter or dry
Often the grind size is too fine. Grind a bit coarser.
The water runs through way too fast or too slow
Compare the brew time with the target range of your recipe: 2:45 to 3:15 minutes for the basic recipe, 3:00 to 3:30 minutes for VERLÄNGERUNG. If it is significantly below that and the coffee tastes thin, grind finer. If it is significantly above and it tastes bitter, grind coarser. If the taste is right, you don't need to change anything. Very vigorous pouring into the center can also change the flow.
Nothing bubbles up during the bloom
Freshly roasted coffee releases carbon dioxide during the first pour and visibly swells. If nothing much happens, it can be a sign that the coffee was roasted a long time ago or ground a long time ago.
The coffee tastes like paper
Thoroughly rinse the filter paper with hot water before brewing and pour the rinse water away.
Frequently asked questions about the hand filter
How much coffee do I need for the hand filter?
My recipe uses 20 g of coffee to 300 g of water. For a smaller cup, you can reduce both in the same proportion, for example, 15 g to 225 g. You may then have to adjust the times slightly.
How fine must the coffee be ground for the hand filter?
Medium. I work with about 650 microns, or 700 microns for VERLÄNGERUNG. What that looks like on your grinder depends on the model.
Which water temperature is correct?
For our light filter coffees, I use 92 to 93 °C. Water that is boiling can make the cup more bitter; significantly cooler water tends to make it sour and thin.
What is the bloom and do I have to do it?
With the bloom, you only pour a little water at first so that the coffee grounds become evenly wet and carbon dioxide can escape. After that, the grounds absorb the remaining water more evenly. In my recipe, that is 60 g of water, with the next pour starting at 0:40.
Hand filter or French Press – which is better?
That is a matter of taste. The hand filter keeps back more oils and particles with the paper; the coffee is usually clearer and lighter. The French press lets more of these through, and the coffee usually has more body.
Can I use pre-ground coffee?
Yes, but ground coffee quickly loses its aroma, and you can no longer adjust the grind size. Grinding fresh is especially worthwhile with the hand filter.
Conclusion
The hand filter requires little equipment but rewards precision. With 20 g of coffee, 300 g of water, 93 °C, and a fixed pouring sequence, you have a reliable starting point. From there, you can adjust step by step according to your taste.
