Clever Dripper Recipe: Ratio, Grind Size and Brew Time
The Clever Dripper steeps coffee off the cup, then releases it through paper when placed on a mug. Start with 15 g coffee and 250 g (8.8 oz) water; learn when to drain, which filter fits and how it differs from the Hario Switch.

Key Takeaways
- 1For the coffee-first recipe, use 15 g coffee, 250 g (8.8 oz) water at 95°C (203°F) and a medium grind.
- 2Keep the Clever off the mug while steeping. At 2:15 from first water, set it on the mug to drain.
- 3Match the paper to your model: commonly #2 for the small Clever and #4 for the large. These are folded trapezoid papers, not pointed V60 cones.

What Is the Clever Dripper?
The Clever is a paper-filtered immersion brewer with a valve activated by the rim of a mug or server. Set it off the cup to hold water, then place it on the cup to drain. It suits a morning routine where one timed steep is easier than repeated controlled pours.
The rim pushes the release mechanism underneath the dripper. This is why brewing on a mug from the beginning produces a different, draining method.
I check the mug against the empty dripper before brewing. It needs to open the valve and hold the whole cup. I'd rather settle that quietly at the start than find myself looking for another mug during drawdown.
How to Brew with the Clever Dripper
Use 15 g coffee and 250 g (8.8 oz) water for one small mug. This coffee-first recipe is adapted from Ozone Coffee's brewing guide. It fits its small 300 ml (10.1 US fl oz) model as well as the larger Clever; leave room to stir. Allow about five minutes with hot water ready.
Recipe
Clever Dripper: 15 g Coffee-First Recipe
- Makes:
- 1 small mug; collected coffee is less than 250 g (8.8 oz)
- Time:
- About 5 minutes with hot water ready; 3–3½ minutes brewing
Ingredients
- 15 g medium-ground coffee
- 250 g (8.8 oz) brewing water at 95°C (203°F)
Equipment
- Clever Dripper, matching paper, lid, sturdy mug or server, scale, grinder, kettle, timer and spoon
Method
- Fold the seams of a correctly sized paper filter and fit it in the Clever. Rinse over a sturdy mug, discard the rinse water, then move the dripper onto its drip tray or a stable level surface so the valve stays closed.
- Add 15 g medium-ground coffee. Start the timer as you pour in 250 g (8.8 oz) water at 95°C (203°F), then stir gently for about 15 seconds to wet every pocket of grounds.
- Fit the lid and leave the dripper off the mug until the timer reaches 2 minutes 15 seconds. This is elapsed time from the first water, not an extra wait after stirring.
- At 2:15, place the Clever securely on the mug or server to open the valve. Allow the coffee to drain, aiming to finish around 3:00–3:30; do not press on the grounds.
- Lift the brewer away, stir or swirl the collected coffee and serve. Once safe to handle, discard the paper and grounds and rinse the brewer.
Recipe notes
Adapted from Ozone Coffee. Start the timer with the first water; release at 2:15.
250 g (8.8 oz) is brewing-water input, not finished cup yield. Keep the valve off the mug while steeping.
A gooseneck kettle is optional: the important part is wetting the coffee evenly, rather than tracing a perfect spiral.
Clever Dripper Ratio, Grind and Timing
250 ÷ 15 = about 16.7, so the starting coffee-to-water ratio is 1:16.7 by weight. To compare strength, keep the water at 250 g (8.8 oz) and try 16 g coffee next time; record the change rather than adjusting every setting together.
Start with a medium filter grind. If the drain is unusually slow, first check the valve and paper fit, then try a coarser grind or gentler stirring. A bitter cup is not proof of one particular extraction fault: roast, concentration and water also matter. The grind-size guide helps compare textures without assuming grinder numbers transfer between machines.
Coffee First or Water First?
Both are established approaches. Ozone puts the grounds in first; Clever's published recipe adds 310 g (10.9 oz) freshly boiled water before 18.5 g coffee, starts its timer with the coffee, and begins release after a much earlier stir. Keep the timings from the recipe you choose.
Water first is worth comparing if grounds settle against the paper and restrict flow. Keep your chosen dose, water and temperature recorded and make the wetting order the deliberate change.
Sizes and Filters

| Model | Common paper | How to use the capacity |
|---|---|---|
| Small, sold as 300 ml (10.1 US fl oz) | #2 folded trapezoid paper | The 250 g (8.8 oz) recipe leaves some room; avoid filling to the rim. |
| Large, sold as 500 ml (16.9 US fl oz) | #4 folded trapezoid paper | More room for stirring or a larger batch; 500 ml (16.9 US fl oz) is not a promised finished serving. |
Ozone’s model specifications identify the small brewer’s size 2 filter. Check the packaging for your specific version. Fold the sealed seams so the filter sits against the walls without crumpling. A pointed V60 paper is a different shape and is not the default substitute. Rinse the filter, then fully discard that water before weighing the recipe water.
Clever Dripper vs. Similar Brewers
| Brewer | What changes in your routine |
|---|---|
| Clever Dripper | Steep away from the mug; set it on the mug to release through paper. |
| Hario Switch | Keep it over a server and operate a manual lever, including during a hybrid brew. |
| French press | Steep and separate with a mesh screen; more suspended particles can reach the cup. |
| Hario V60 | Water drains as you pour; flow, grind and pour pattern interact. |
| AeroPress | Use gentle hand pressure to push coffee through the filter. |
The Clever's paper gives a less gritty cup than a mesh-filtered French press. Flavor and body still depend on the coffee and recipe. Choose the Switch for manual valve control, or V60 if you enjoy working with a continuous pour.
Clever Dripper Troubleshooting
| Problem | First check or adjustment |
|---|---|
| Coffee drains while you meant to steep | Move the brewer off the mug. Check that nothing presses the release foot; inspect the seal once cool. |
| No drainage when placed on the cup | Check that the rim actually activates the base and supports it safely. Try a compatible server; do not poke at the hot valve. |
| Drain slows to a trickle | Check folded paper and heavy fines. Next brew, stir less or grind a little coarser; do not squeeze the paper. |
| Cup tastes weak | Confirm the measured dose and any added milk or water. Try slightly more coffee while keeping the water fixed. |
| Cup tastes harsh or drying | Try less agitation or a coarser grind as a single change; consider the coffee’s roast too. |
Cleaning the Valve
Remove the used paper and grounds, rinse away residue and clean gently with mild detergent. Sweet Maria’s cleaning guidance emphasizes regular rinsing and cleaning suited to the brewer. Let it cool before inspecting the underside. If the seal is damaged or the mechanism is sticking, follow the care instructions supplied with your model rather than forcing it. Recheck the valve with cool water after reassembly.
Caffeine, Calories and Serving Size
A 200 g (7.1 oz) serving of generic brewed black coffee represents about 80 mg caffeine, 2 kcal and 0 g sugar in USDA reference data. Milk, sugar and syrups change the nutrition. The recipe's water weight is an input, not a measured serving yield.
Serving assumptions and sources
USDA brewed coffee, NDB 14209, lists 40 mg caffeine, 1 kcal and 0 g sugar per 100 g; the example doubles those values. This is a generic serving reference, not a measurement of this brewer or recipe. Some water remains in the discarded grounds.
Common Questions Before You Brew
Is It a Good Brewer for Beginners or the Office?
Yes, if a paper-filtered single cup and a timed steep suit your routine. You need a kettle and somewhere stable to keep the brewer off the mug, but a specialized pouring kettle is unnecessary. Paper cleanup is straightforward; the valve still needs rinsing.
Does Clever Coffee Need a Separate Bloom?
This recipe does not use one. Pour the full water amount and wet the grounds gently. A separately timed bloom is a different recipe choice, not an omitted essential step here.
Can You Use Pre-Ground Coffee?
Yes. Start with medium filter-ground coffee and the measured recipe. If an espresso-fine grind clogs the paper, use a more suitable grind next time rather than extending the drain indefinitely.
Can You Make Iced Coffee?
Yes, with a recipe that budgets hot water and ice separately. Brewing this full recipe over an unmeasured pile of ice changes concentration and serving size. See Japanese iced coffee for the hot-brew-over-ice principle.
