How Long Does It Take Moka Pot to Brew and What Ratio to Use
For a single pour-over cup, 15 grams of coffee is a common starting dose. To land within the SCAA concentration range of 1.2 to 1.45 percent, the ratio of grounds to poured water should stay between 1:12 and 1:15. At 1:15, 10 grams of grounds would mean 150 grams of total poured water, and that ratio is the parameter used in Front Street Coffee shops.
The 1:15 figure was not chosen at random; it came from repeated testing, while 1:12 to 1:15 remains a suggested range rather than a rule. Extraction ratio differs from espresso, which uses far less water per gram of coffee. Grind size, pouring rhythm, and the three-stage pour all feed into the same result, so a consistent framework matters more than any single number.
The flavor expression of pour-over coffee is closely related to the coffee dose, grind size, coffee-to-water ratio, and pouring technique. For an ideal cup of pour-over coffee, exactly how much coffee grounds should be used and how much water should be paired with it? Front Street Coffee takes 15 grams of grounds as an example, combines it with SCAA concentration recommendations, analyzes the coffee-to-water ratio range of 1:12 to 1:15, and explains why 1:15 has become a commonly used parameter in shops. The article also compares the extraction ratio differences of espresso, and includes the complete brewing data and three-stage operation details of Front Street Yirgacheffe Gedingding, helping enthusiasts build a replicable brewing framework.

Pour-over coffee has quite high requirements for operational details. Factors such as the amount of coffee beans used, grind coarseness, coffee-to-water ratio, and pouring rhythm all directly influence the flavor direction of the final cup. To consistently brew a satisfying pot of pour-over coffee, it is necessary to first understand the relationships among the various parameters. Below, Front Street Coffee sorts out the brewing methods and key parameters of pour-over coffee for coffee enthusiasts.
How many coffee beans should be weighed for pour-over coffee?
Taking Front Street Coffee's pour-over output as an example, a single cup usually uses 15 grams of coffee beans. This amount refers to the recommendation of the SCAA, the Specialty Coffee Association of America—experiments show that the most suitable taste is achieved when coffee concentration falls within the range of 1.2% to 1.45%.
To fall within this concentration range, Front Street Coffee has calculated that the ratio of coffee grounds to poured water should be controlled between 1:12 and 1:15. If calculated at 1:15, weighing 10 grams of grounds means the total poured water amount is 150 grams.
From this it can be seen that a coffee-to-water ratio of 1:15 is a relatively ideal solution. At present, the pour-over parameter set for Front Street Coffee shops is 1:15. This value was not chosen arbitrarily; Front Street Coffee had previously conducted repeated tests. Although 1:12 to 1:15 is only a suggested range, Front Street Coffee additionally verified several ratios outside the range.
The test results showed that drip coffee at 1:20 tastes very weak, while 1:10 is too strong. After comparison and adjustment, Front Street Coffee believes that 1:15 has good adaptability for most coffee beans. Of course, some people prefer 1:14 or 1:17, and there is nothing wrong with that; the key is whether the individual can accept it. What Front Street Coffee provides is only a reference value with relatively high public acceptance.
Once the coffee-to-water ratio is determined, the next step is to clarify the total amount of a cup of coffee. Front Street Coffee usually extracts a single cup of pour-over to 225 grams, exactly one serving, that is, using 15 grams of coffee grounds to extract 225 milliliters of liquid.
In other words, a 225-milliliter serving of coffee liquid corresponds to 15 grams of coffee beans. This conclusion is derived precisely from the optimal coffee-to-water ratio for pour-over coffee.
What is the difference between the coffee-to-water ratio of espresso and pour-over?
According to Front Street Coffee's understanding, the models of espresso machines used by different coffee shops are not the same, so extraction parameters naturally differ, and therefore there is no unified standard for the coffee-to-water ratio of espresso. Taking espresso as an example, Front Street Coffee usually uses 10 grams of coffee grounds to extract 20 milliliters of espresso, that is, a 1:2 ratio.
However, there is no universally applicable extraction ratio, and it still needs to be adjusted according to the actual condition of the espresso machine. There are some unwritten conventions in the industry, namely referring to the parameters used by respected coffee leaders as general values, gradually forming benchmarks. At the same time, Front Street Coffee also notes that espresso varies depending on extraction time, and the ratio expressions of short-time refined extraction and long-time extraction each have their own conventions.
The following are the common espresso water-to-coffee ratios in major coffee shops at present:
The extraction ratio of ristretto is between 1:1 and 1:1.5.
The extraction ratio of regular espresso is between 1:1.5 and 1:2.5.
The extraction ratio of lungo is between 1:2.5 and 1:3.
The above is Front Street Coffee's summary of the amount of coffee beans used for pour-over coffee, as well as answers related to the water-to-coffee ratios of pour-over and espresso. Next, Front Street Coffee will share the extraction parameter process of espresso and the brewing steps of pour-over coffee for everyone's reference.

When the water level drops to 2/3 of the coffee bed, pour the remaining 100 grams (the electronic scale shows about 225 grams), finishing the pour in about 1 minute 35 seconds. Dripping is completed at 2'00"-2'10". Remove the dripper and the extraction is complete.
Washed Gedingding brewing flavor: On entry there are citrus and black tea; as the temperature changes, there are cream, caramel, and almond, with a clear sweet aftertaste and a clean, sweet taste.
From the above, it can be seen that the brewing method used by Front Street Coffee for pour-over coffee is three-stage extraction. This is also the part of the entire pour-over coffee process that places demands on one's own operation. So exactly how can three-stage extraction be controlled well? What is blooming? Next, Front Street Coffee will explain it for everyone!
Coffee brewing method—three-stage brewing method
At present, there are many kinds of pour-over coffee brewing methods seen in coffee shops, and the commonly seen ones include the three-stage method, one-cut method, drip method, and so on. Here Front Street Coffee suggests that beginners use the three-stage pouring method to brew, because this method is suitable for light-roasted, medium-light, and medium-roasted coffee beans. The segmented extraction method of three-stage pouring can clearly define the front, middle, and back flavors of the coffee, and can relatively ensure the presentation of the coffee's flavor.
First pour: bloom (helps degassing)
Many coffee enthusiasts do not know the meaning of blooming in pour-over coffee. In fact, blooming is needed because coffee beans undergo a series of chemical reactions and physical changes during the roasting process from green beans to roasted beans. After reaching a certain degree of roasting, a large amount of gas (mostly carbon dioxide) accumulates inside the coffee beans.
Generally speaking, the fresher the beans and the closer to roasting, the more bubbles usually appear during blooming. Dark-roasted beans also release more gas during blooming than light-roasted beans. Front Street Coffee's coffee beans are all freshly roasted, so customers are generally advised to rest the beans for three days first, letting the coffee beans release carbon dioxide first, so that in brewing the problems of instability and under-extraction can be avoided.
After the gas is released during blooming, the coffee particles can absorb water evenly, allowing later extraction to be uniform. A good bloom can allow the coffee grounds to quickly and fully degas while also allowing the coffee grounds to fully and quickly contact water, helping the coffee grounds be evenly extracted. These are precisely the purpose and significance of blooming in pour-over coffee.
During the bloom of pour-over coffee, pay attention to the following four points:
1. Before pouring for the bloom, first level the coffee grounds.
2. When pouring during the bloom, do so gently.
3. During the bloom, the extracted liquid flowing down should be as little as possible; when too much extracted liquid appears in the server, reduce the poured water amount, or pay attention to the grind size. (If the bloom water amount is too much, a large amount of coffee liquid drips down, and the falling water does not stay but directly carries out substances from the outside of the coffee grounds; the off-flavors and astringency from the outer layer of the coffee grounds also begin to dissolve out. The coffee brewed this way is both weak and yet has off-flavors from over-extraction. If the bloom water amount is insufficient and no water drips down at all, then the coffee grounds have not absorbed enough water, some coffee has not degassed sufficiently, causing under-extraction.) Based on this situation, after many bloom tests, Front Street Coffee found that pouring water at twice the amount of coffee grounds during the bloom is relatively suitable.
4. The bloom time is about 30 seconds. When the expansion on the surface of the coffee grounds ends, you will see the coffee surface begin to shrink, which means the bloom is complete and pouring can begin. (In terms of time, if the bloom time is too long, the coffee is prone to bitterness and astringency; if the time is too short, the soaking is insufficient, and the coffee may be under-extracted or unable to fully present itself.) Generally speaking, the end time of the bloom differs for each bean, but Front Street Coffee found that this is not conducive to beginners' operation. After all, beginners value standardization and ease of use. Therefore, under the premise of ensuring that the coffee beans are still freshly roasted, Front Street Coffee suggests a bloom time of 30 seconds. Of course, experienced people can adjust the time themselves.
Second pour
The second pour starts from the center, with a small stream poured into the bottom of the coffee bed. In order to concentrate the penetrating force of the stream, the range of circular movement should be small, about the size of a one-yuan coin, and then circle outward. From the start of the second pour, pay attention to the water amount, and try not to exceed the height of the coffee bed. That is, when the stream circles to near the filter paper, you can stop pouring.
Third pour
As the originally thicker coffee bed near the edge of the filter paper becomes heavier from absorbing water, it slides down and becomes thinner as the water level drops. When the water level drops to halfway, the third pour can be carried out. From the start of the third pour, observe the extent of the water level drop. Likewise, start pouring from the center in a circular motion, and the water amount should not exceed the height of the coffee bed. At this time you will also observe that the foam has filled the surface. In the third pour, increase the tumbling of the coffee particles so that all the settled particles tumble, thereby dissolving soluble substances.
The rolling particles will begin to stop when pouring stops. At this time, it relies on the flow rate caused by the dropping water level to create friction among the coffee particles. Therefore, once pouring stops, the coffee particles sink downward, causing clogging, so pay special attention to the rhythm of pouring. If pouring is interrupted too many times, it is equivalent to letting the coffee particles remain soaked in water, which will cause the coffee extraction in the final stage to produce astringency and off-flavors. If pouring is interrupted too many times, it is equivalent to letting the coffee particles remain soaked in water, which will cause the coffee extraction in the final stage to produce astringency and off-flavors.
The above is the process for operating the three-stage extraction of pour-over coffee. I hope it can help coffee enthusiasts who want to try pour-over coffee themselves, so that in the future they can brew a cup of coffee they are satisfied with!
