Pour-Over Brew Time Guide for Light to Medium Roasts

Ever pulled a pour-over that tasted thin or overly bitter? Many home brewers rush the process or let it run too long, missing the sweet spot where clarity, balance, and complexity shine. The secret isn’t just in the grind or water temperature—it’s how long you let the water interact with the coffee grounds.

For light to medium roasted coffee using a Kalita-style pour-over at 3.5 settings (medium-fine grind), the ideal total brew time—including pre-wetting—is 2 to 3 minutes 40 seconds, depending on your dose. Here’s how to get it right every time.

Why Brew Time Matters in Pour-Over

Brew time directly affects extraction yield—the percentage of soluble coffee material pulled into your cup. Too short, and you leave behind acids, sugars, and aromatics, resulting in a flat, sour, or 'underdeveloped' cup. Too long, and you risk over-extracting bitter tannins and astringent compounds, leaving your coffee harsh and unpleasant.

The goal in specialty coffee is to land in the “golden cup” range: 18–22% extraction yield and 1.15–1.55% TDS (total dissolved solids). To reach that window consistently, your pour-over time needs to align with your dose and roast level.

How Long Should Your Pour-Over Take?

Based on training at FrontStreet Coffee using a small Falcon dripper at 3.5 grind setting, here are the recommended total brew times—starting from bloom/pre-infusion—for different coffee doses:

• 15–20 grams: 2 minutes to 2 minutes 30 seconds total brew time
• 21–25 grams: 2 minutes 30 seconds to 3 minutes total brew time
• 26–30 grams: 3 minutes to 3 minutes 40 seconds total brew time

These timings include the initial bloom and any subsequent pours. The actual contact time may vary slightly based on pour rate and technique.

What Determines the Right Brew Duration?

Several factors influence how long your pour-over should take:

• Dose: More coffee grounds require slightly longer contact time to fully extract.
• Roast level: Lighter roasts typically need more time due to denser cell structures; darker roasts extract faster and can become bitter if brewed too long.
• Grind size: Finer grinds slow flow rate and increase extraction time; coarser grinds do the opposite.
• Flow rate: A narrow-spout kettle like the Kalita allows more control, helping maintain an even and slower pour that extends contact time without overcomplicating the process.

In general, aim for a minimum of 2 minutes to ensure enough extraction. Going beyond 2 minutes 30 seconds increases the risk of over-extraction, especially with finer grinds. With larger doses (26–30g), extending toward 3:40 is acceptable, particularly with lighter roasts or higher doses.

Pour-Over Best Practices & Common Mistakes

Brew time isn’t the only variable—but it’s a critical one. Here are key guidelines and pitfalls to avoid:

• Minimum brew time: Never go under 2 minutes. Below this, your coffee will likely taste weak, sour, and lack complexity—classic signs of under-extraction.
• Maximum brew time: Avoid exceeding 3 minutes 40 seconds unless you're intentionally working with a larger dose and lighter roast. Longer times often lead to bitterness and dry tannins.
• Flow control: A narrow-spout kettle (like Kalita) gives you more precision in pouring slowly and steadily. Wider spouts can work too, but require better technique to avoid dumping water too fast.
• Avoid thick beds: Japanese-style pour-overs generally shouldn't exceed 30 grams of coffee, as thicker layers can cause uneven flow and longer, unstable brews. Likewise, doses under 15g can be harder to control for beginners.

Mastering pour time means practicing how you pour—not just how long you let it go. Being able to adjust your flow on the fly ensures you hit the target time without sacrificing even extraction.

Frequently Asked Questions

What is the ideal total brew time for a 20g pour-over?

For a 20g dose of light to medium roast coffee using a medium-fine grind (around setting 3.5), the ideal total brew time—including bloom—is 2 to 2 minutes 30 seconds. This helps achieve balanced extraction without over- or under-extracting the coffee.

Does roast level affect pour-over brew time?

Yes. Lighter roasts usually require slightly longer brew times (closer to 2:30–3:00 for larger doses) due to their denser structure, while darker roasts extract more quickly and should be brewed closer to the minimum time (around 2:00) to avoid bitterness.

Can I brew a 30g pour-over in under 3 minutes?

It’s not recommended. For doses of 26–30g, especially with lighter roasts, the total brew time should be 3 to 3 minutes 40 seconds. Brewing a 30g dose too quickly can lead to under-extracted, sour, or thin coffee.

What happens if my pour-over finishes in under 2 minutes?

If your brew finishes in less than 2 minutes, it’s very likely under-extracted. You’ll likely taste sourness, a thin body, and a lack of sweetness or complexity. Always aim for at least 2 minutes of total contact time.

How does grind size impact brew time?

Finer grinds slow down water flow, increasing brew time and extraction. Coarser grinds speed it up, potentially leading to under-extraction. For the recommended 2–3:40 minute range, a medium-fine grind (around 3.5 on a small Falcon setting) is ideal.
