How to Use a Clever Dripper
Brew great coffee with a Clever Dripper: 18 g to 300 g, water first, 2-minute steep and a 1-minute drain. Plus grind fixes, iced coffee, how the valve works and a step-by-step brew timer.

The Clever Dripper looks like an ordinary pour over cone, but it has a valve in the bottom. Pour in water and coffee, and they stay put and steep, like in a French press. Set it on your mug, and the valve opens and the coffee drains through a paper filter, like a pour over. You get the rich, sweet body of immersion with the clean cup of a paper filter, and there’s no pouring technique to learn. It’s one of the most forgiving brewers there is, which makes it ideal for busy mornings.
- Ratio: about 1:16.7. 18 g of coffee to 300 g of water makes one large mug.
- Grind: medium-fine to medium, like table salt.
- Water: just off the boil, about 95–96 °C.
- Method: water in first, then the coffee. Stir, lid on, steep 2 minutes, stir again.
- Drain: set it on your mug at 2:30. Done by about 3:30.
The brew timer at the top of this page tells you when to stir and when to drain. Choose Water first or the classic Coffee first method.
How the Clever Dripper works
The trick is a spring-loaded valve in the base. On the coaster, on a scale or on the counter, it stays closed, so the water and coffee sit in the cone and steep. When you put the Clever on a mug or a jug, the rim pushes the valve open and the coffee drains through the filter. Lift it off, and it closes again.
1. Steep. On the coaster or scale, the valve stays shut.
2. Drain. On a mug, the rim opens the valve.
The Clever comes in two sizes: a small one (about 11 oz) for a single cup and a large one (about 18 oz) that holds up to roughly 450 g of water. It takes standard cone paper filters (size 4 for the large). It’s made by Abid, a Taiwanese company.
What you need
- A Clever Dripper and size 4 cone paper filters (size 2 for the small Clever).
- A burr grinder. See our coffee grinder guide.
- A kitchen scale and a timer (or the timer above).
- Any kettle. No gooseneck needed: you just pour the water in.
Clever Dripper ratio
Start at 1:16–1:17, about 60 g of coffee per litre of water. The paper holds back about twice the coffee’s weight in water, so you’ll end up with a little less in the mug than you poured.
| Brew size | Coffee | Water |
|---|---|---|
| 1 cup | 15 g · 3 tbsp | 250 g (8½ oz) |
| 1 large mug | 18 g · 3½ tbsp | 300 g (10 oz) |
| 2 cups (large Clever, full) | 27 g · 5½ tbsp | 450 g (15 oz) |
For other amounts, use our coffee-to-water ratio calculator.
Grind size
Use a medium-fine to medium grind, about like table salt: somewhere between pour over and drip. Because the coffee steeps, the grind matters less than in a pour over, but it still controls the drain. The drain is your guide: it should take about 1–1½ minutes. If it takes 2 minutes or more, grind coarser. If the coffee tastes sour or thin, grind finer or steep a little longer. Our coffee grind chart shows the sizes side by side.
Water first or coffee first?
The classic way is to add the coffee, then pour the water over it. James Hoffmann popularised the reverse: water first, then the coffee. When you pour water onto dry coffee, the finest particles get washed straight down onto the paper and clog it, so the drain slows down. If the water goes in first, the grounds float and mix in, and the drain is faster and more even. It’s the default in our timer, but both methods work well, so try both and see which you prefer.
How to use a Clever Dripper, step by step
This recipe makes one large mug: 18 g of coffee and 300 g of water, the Water first recipe in our timer.
1. Rinse the filter
Fold the paper filter along its seams and put it in the Clever. Pour hot water through it, then set the Clever on a mug to drain the rinse water out, and tip it away. This removes the papery taste and warms everything up.
2. Add the water (0:00)
Put the Clever on its coaster on your scale and tare it. Start the timer and pour in 300 g of water, just off the boil.
3. Add the coffee and stir (0:15)
Tip in 18 g of coffee and stir gently until there are no dry clumps. Put the lid on to keep the heat in.
4. Steep, then break the crust (2:00)
Leave it to steep. At 2:00, take the lid off and stir gently (or give it a swirl), so the crust of grounds on top sinks.
5. Drain (2:30–3:30)
At 2:30, set the Clever on your mug. The valve opens and the coffee drains through the paper in about a minute. When it’s done, lift it off and put it back on the coaster. The grounds should end up as a flat, even bed.
Pro tip: the Clever is the easiest way to make great iced coffee. Brew 20 g of coffee with 200 g of hot water as usual, one step finer, and drain it straight onto 120 g of ice in a jug. It chills instantly and keeps its aroma, and the ratio including the ice is about 1:16.

Troubleshooting
| What happened | Likely cause | Try this |
|---|---|---|
| Sour, thin | Grind too coarse, or steep too short | Grind finer, or steep 30 seconds longer. |
| Bitter, dry | Grind too fine, or steeped too long | Grind coarser. Drain at 2:30, not later. |
| Slow drain (2+ minutes) | Fines clogging the paper | Grind coarser. Add water before coffee. |
| Won’t drain on the mug | Mug too narrow or too wide to press the valve | Use a standard mug or a jug with a rim the base can sit on. |
| Leaks on the counter | Grounds stuck in the valve | Rinse the valve well and press it a few times under water. |
| Papery taste | Unrinsed filter | Rinse the filter with hot water first. |
Clever vs French press and pour over
| Body | Clarity | Skill needed | |
|---|---|---|---|
| Clever Dripper | Medium | High | Very little |
| French press | Full | Low | Very little |
| Pour over | Light to medium | High | Some practice |
The Clever is as easy as a French press, but the paper filter gives you a clean, sediment-free cup, and it holds back the coffee oils that can raise cholesterol (see our French press guide). Compared with a V60, you give up a little brightness and control, but you also lose the need for a gooseneck kettle and careful pouring. It’s a very good first brewer, and a great travel brewer too.
What coffee works best?
Almost anything. Immersion brewing is forgiving, so the Clever makes a sweet, balanced cup from medium roasts and does a good job with light roasts too: a washed Colombian or Guatemalan for chocolate and caramel, or an Ethiopian for fruit and florals. For dark roasts, use water a little cooler (about 90 °C) and keep the steep at 2 minutes.
Cleaning
Lift out the filter with the grounds and put it in the compost. Rinse the Clever under hot water, pressing the valve a few times so no grounds stay trapped in it. Once a week, wash it with warm soapy water and a soft brush. Avoid abrasive scourers on the clear plastic. If coffee stains build up, soak it in warm water with a little coffee-cleaning powder.
Clever Dripper FAQ
It’s a cone dripper with a spring-loaded valve in the base. On the counter or a scale the valve stays closed, so the coffee steeps like a French press. Set it on a mug, and the rim pushes the valve open so the coffee drains through a paper filter.
Start at about 1:16.7: 18 g of coffee to 300 g of water for a large mug, or 15 g to 250 g for a smaller cup. A large Clever holds up to about 450 g of water, enough for 27 g of coffee.
About 2 to 2½ minutes, then drain. The drain itself should take about a minute, so the whole brew takes around 3½ minutes. Steep longer with a coarser grind if you like a stronger, heavier cup.
Either works. Adding water first, then coffee, keeps the finest particles from clogging the paper, so the coffee drains faster and more evenly. The classic coffee-first method is fine too, especially with a slightly coarser grind.
Standard cone paper filters: size 4 for the large Clever and size 2 for the small one. Rinse them with hot water first to remove any papery taste.
The valve only opens when the base sits on a rim. If your mug is very narrow or very wide, the base can’t press the valve. Use a standard mug or a jug. If it drains very slowly, grind coarser and add the water before the coffee.
It’s as easy, but the paper filter gives a cleaner cup with no sediment and removes most of the coffee oils, including cafestol, which can raise cholesterol. A French press has more body. If you like a clean cup, the Clever is the better everyday brewer.
