Coffee Ratio for Kalita Wave (2026): 155 & 185 Recipes

What coffee ratio should you start with for a Kalita Wave?

Start with 1:16, or one gram of coffee for every 16 grams of water. It sits between the 1:15 Crema recipe and 1:16 Onyx recipe documented in Prima Coffee’s Kalita recipe comparison, so it is a sensible everyday baseline. Treat the ratio as a strength control, then use grind size and pouring to correct extraction.

What do you need to measure a Kalita Wave recipe?

You need fresh coffee, a Kalita Wave and filter, hot water, a burr grinder, and a scale that reads grams. Scoops are fine for camping, but they cannot hold a 1:16 ratio steady. A precise coffee scale makes ratio brewing effortless, especially when you want to repeat a great cup.

• Kalita 155: 15g coffee and 240g water for one generous cup.
• Kalita 185: 25g coffee and 400g water for two modest servings.
• Water: about 200°F / 93°C, just off the boil.

How do you brew the 1:16 Kalita Wave recipe?

For a dependable Kalita 155 cup, brew 15g of medium-ground coffee with 240g water and aim for a total brew time near three minutes. Pulse pours help keep the slurry from overflowing and make it easier to keep the bed level. Prima Coffee’s comparison includes successful Kalita recipes that use this same basic rhythm, although exact timing should follow your coffee and grinder.

Step 1: Rinse the filter and weigh 15g of coffee

Set the dripper over your mug, rinse the filter with hot water, and discard that water. Add 15g of coffee ground medium, like table salt, then gently shake the brewer until the bed looks flat.

Step 2: Bloom with 45g water for 45 seconds

Start your timer and pour 45g in slow circles, making sure no dry pockets cling to the paper. The bloom wets the bed before the main pours; a level, evenly saturated bed gives you a more useful baseline for the next brew.

Step 3: Pour to 150g, then 240g

At 45 seconds, pour steadily to 150g. When the water level drops close to the grounds, pour again to 240g. Keep the stream gentle and mostly inside the coffee bed; a gooseneck kettle gives you the pour control needed for even extraction.

Step 4: Let it drain, then taste before changing anything

Use roughly 2:45 to 3:30 as a starting window, not a pass-or-fail target. A Kalita guide from Extracted Magazine likewise uses repeated pours as the slurry drops. Taste the coffee once it has cooled slightly, then change either grind or ratio—not both—on the next brew.

What throws a Kalita Wave ratio off?

The ratio is only repeatable when coffee dose, water weight, and grind stay consistent. The Kalita’s flat bed and three drain holes are designed to promote even flow, but an uneven pour or changed grind setting can still make the same 15g-to-240g recipe taste completely different.

• Measuring by scoop — weigh both coffee and water. A heaped scoop can quietly turn a balanced brew into a thick, harsh one.
• Pouring hard against the paper — this can send water around the coffee bed and leave the cup watery. Pour calmly in the center and small circles.
• Changing ratio and grind together — you will not know which change helped. Make one adjustment, taste, then decide.

How should you adjust the ratio when your coffee tastes off?

Use ratio to change concentration: move to 1:15 for more body or 1:17 for a lighter-strength cup. Use grind to address extraction: finer for a fast, sour brew and coarser for a slow, bitter one. Our picks for the best pour-over coffee grinders can help you get the even particles that make these small changes predictable.

Weak, sour, or watery

If the cup is thin but otherwise pleasant, try 16g coffee to 240g water. If it is sour or the brewer empties much faster than about 2:45, keep 1:16 and grind a little finer first; water likely did not spend enough time extracting sweetness.

Bitter, dry, or too heavy

If the cup is bitter or drying, grind a touch coarser. If it tastes balanced but too concentrated, try 14g coffee to 240g water instead. A drawdown that drags beyond 3:30 can mean the bed is too fine or clogged with fines.
