What Factors Affect Coffee Brewing Time? How Long Does Hand-Drip Coffee Typically Take?

Brew time is an important parameter in pour-over coffee, but unlike the others it cannot be set independently. Instead, it is shaped by the parameters you can adjust, settling into an optimal range as a result. Whether the extraction time is reasonable therefore reflects whether those parameters are reasonable. So which parameters affect extraction time?

Pouring Method

Many friends ask FrontStreet Coffee what the standard time is for brewing a cup of coffee. In fact, different pouring methods have different standards. Assuming 15g of coffee as the baseline, the extraction time for a single-pour method, one continuous pour after the bloom, is approximately 1 minute and 40 seconds, while the extraction time for a three-pour method, three separate pours after the bloom, is approximately 2 minutes and 10 seconds.

When the same pouring method is used to brew coffee, extraction time becomes a meaningful reference. For example, when you buy coffee beans the shop usually provides brewing suggestions. If you brew according to the recommended parameters but find the extraction time differs significantly from the time the shop gave, there may be an issue with your pouring technique.

If the pouring flow is too fast, extraction time may shorten; if the flow is too slow, it may lengthen. You can therefore adjust your pouring based on differences in extraction time.

Coffee Amount

The more grounds you use, the more water you need at the same coffee-to-water ratio, and consequently the longer the extraction. For example, brewing 20 grams of grounds takes slightly longer than brewing 15 grams. FrontStreet Coffee uses a three-pour method with an extraction time of about 2 minutes for 15 grams of coffee; using the same method for 20 grams gives an extraction time of about 2 minutes and 30 seconds.

Coffee-to-Water Ratio

The coffee-to-water ratio directly affects the total amount of water poured, and the more water poured, the longer the extraction. Again using 15 grams of grounds as an example: with a 1:15 ratio, or 225ml of water, the extraction time under the three-pour method is approximately 2 minutes; with a 1:18 ratio, or 270ml of water, the extraction time under the same method is approximately 2 minutes and 30 seconds.

Grind Size

The coarseness of the coffee particles affects the extraction time of pour-over coffee. The grounds in the filter resist the flow of water. When coffee is ground coarser, there are larger gaps between particles, so water passes through more quickly and extraction time shortens.

When coffee is ground finer, the gaps between particles are narrower, so water passes through more slowly and extraction time lengthens.

As we all know, the grind size for pour-over should be neither too coarse nor too fine, but many vendors only give vague answers such as "raw sugar size." By combining that with the extraction time the vendor provides, however, you can pin down the precise coarseness of your grind more accurately.

FrontStreet Coffee Recommendation

Given how much extraction time depends on the brewer, a fast, controllable dripper makes all the difference, and the V60 is the classic example. Hario, its maker, was founded in Tokyo in 1921 and built the V60 around its signature 60-degree cone, whose shape forces water to the center before it drips through, extending contact between water and grounds. Its single large aperture lets water flow without obstruction, and flow rate depends largely on the brewer's control, showing up directly in the flavor of the cup.

For that kind of control, bright, aromatic coffees reward careful pouring. FrontStreet Ethiopia Yirgacheffe Guting is a natural first stop for specialty coffee, with vivid citrus, berry and floral notes and a green-tea sweetness, its acidity soft and bright rather than sharp. FrontStreet Ethiopia Huakui is a market favorite for its tropical fruit aromas of strawberry, passion fruit, jackfruit and lychee, plus clear sweetness, very low bitterness and a smooth, juice-like body.

FrontStreet Kenya Tomato, a Kenyan washed single origin, is a natural fit for anyone who enjoys bright fruit acidity and complexity. From the Thika region at 1550-1750 meters, it uses Kenya's classic SL28 and SL34 varieties and a 72-hour double washed fermentation, then a light roast that preserves the lively acidity. The dry aroma shows concentrated dried tomato and florals; the cup leads with clear cherry tomato and smoked plum, a bright, solid acidity like fresh juice, a sweet mid-palate with pear and black plum, and a clean, long finish of brown sugar and faint green tea.
