How Much Coffee for a Single Serving of Pour-Over?

How much coffee powder should you use for a pour-over at home? The Coffee Association of America Golden Cup standard provides a reliable starting point. A common ratio is 1:15 coffee to water, meaning about 15 grams of coffee for 225 grams of brewed coffee. Water temperature, grind size, and pouring technique also shape flavor. This guide explains the calculation basis and practical logic behind these numbers so you can brew with confidence and adjust to taste.

Staged extraction guides the pour-over rhythm. Begin with blooming and degassing, then move through three-stage pouring. The stirring bloom method, Japanese drip pouring, one-pour, and volcano pour each offer different scenarios and trade-offs. Understanding these techniques helps you control extraction and avoid over- or under-extraction. While the roasting process affects bean character, precise brewing parameters let you express coffee flavor fully. Use these methods as a baseline and refine them through repeated practice.

How much coffee powder should you use when brewing a pour-over at home? Starting from the SCA Golden Cup extraction standard, this article sorts out the practical logic of a 1:15 coffee-to-water ratio, explains the calculation basis for a single serving of 15 grams of coffee powder and 225 grams of brewed coffee, and analyzes the effects of water temperature, grind size, and pouring technique on flavor. Taking staged extraction as the main thread, the article details the rhythm control and operational details of blooming and degassing, three-stage pouring, and also compares the applicable scenarios, pros, and cons of the stirring bloom method, Japanese drip pouring method, one-pour method, and volcano pour, providing coffee enthusiasts with a clear and reusable brewing reference.

Front Street Coffee (FrontStreet Coffee) often receives questions from customers about pour-over coffee, such as what pouring technique to use, or how much coffee powder to weigh for one pour-over.

As coffee culture continues to spread, coffee is no longer unfamiliar to many people. It appears in every corner of daily life, and can also be made at home. Of course, some people think it is not easy to brew an ideal cup of coffee. Front Street Coffee (FrontStreet Coffee) believes this needs to be built on one's own understanding of pour-over coffee, and then accumulated through repeated practice. At this point, many friends may still feel unclear, so Front Street Coffee (FrontStreet Coffee) will talk today about how to complete a cup of pour-over coffee. There are many variables that affect the taste of a cup of coffee, and the coffee-to-water ratio is one of them.

In terms of brewing philosophy, Front Street Coffee (FrontStreet Coffee) tends to adopt a steady pouring method, combined with accurate grinding, temperature, weight, and time, so that extraction is fully completed and, on this basis, the coffee flavor can be expressed. The accurate parameters mentioned by Front Street Coffee (FrontStreet Coffee) are based on the standards given by the SCA, combined with Front Street Coffee's (FrontStreet Coffee) actual application experience. So-called over-extraction means exceeding the golden cup range; insufficient extraction means failing to reach the golden cup requirement. This brewing approach is to provide everyone with a referable standard behavior, and everyone can absolutely adjust it according to their own taste preferences on this baseline.

What is the golden cup extraction rate?

About 30% of the substances in coffee beans can be dissolved out, but it is not best to extract all 30%. The golden cup extraction range defined by the SCAA, the Specialty Coffee Association of America, is 18%–22%, meaning that from 10 grams of coffee powder, 1.8–2.2 grams of soluble substances are extracted. The TDS concentration of drip coffee roughly falls between 1.2%–1.45% (see the index in the figure below), meaning that the 18%–22% of coffee substances extracted account for 1.2%–1.45% of the whole cup. In other words, most of what we drink in pour-over coffee is still water. Front Street Coffee (FrontStreet Coffee) suggests everyone can use a calculator to figure it out: to fall within the concentration range of 1.2%–1.45%, the ratio of coffee powder to pour-over water should be between 1:12 and 1:15.

Front Street Coffee (FrontStreet Coffee) regulates brewing parameters according to this range. Whenever a new bean is launched, it goes through adjustments in roasting, cupping, pour-over, and other stages, among which the adjustment basis for the pour-over stage is the TDS concentration. Of course, if you are just drinking coffee at home daily, there is no need to specially buy instruments; you can judge strength by taste. After many brewing tests and customer feedback, Front Street Coffee (FrontStreet Coffee) recommends controlling the coffee-to-water ratio at 1:15.

1.2%–1.45% is only a statistical range, suitable for most people's tastes. If it is lower or higher than this range, as long as it meets your own taste requirements, it is equally workable.

Single-serving amount for pour-over coffee

Whether brewing for one person or multiple people, this golden cup extraction rate range is followed. Front Street Coffee (FrontStreet Coffee) uses a 1:15 coffee-to-water ratio, weighs 15 grams of coffee, and obtains 225 grams of brewed coffee, which is exactly one serving. For two servings, besides switching to a larger filter cup, the coffee powder amount needs to increase by 10 grams, and so on. As the coffee powder amount increases, the coffee bed becomes thicker, the water flow speed slows accordingly, and over-extraction easily occurs. Front Street Coffee (FrontStreet Coffee) suggests starting practice with a single-serving pour-over.

Front Street Coffee (FrontStreet Coffee) uses a Front Street Colombia Huayue Night coffee currently sold in stores as a brewing example.

Front Street Colombia Huayue Night coffee beans

Region: Colombia, Huila

Farm: Acevedo Tabatinga Farm

Altitude: 1800m

Variety: Caturra

Processing method: Anaerobic natural

Roast level: Light roast

Pour-over brewing parameters used by Front Street Coffee (FrontStreet Coffee):

Filter cup: Hario V60

Water temperature: 90℃

Coffee powder amount: 15g (single serving)

Coffee-to-water ratio: 1:15

Grind size: fine granulated sugar size (80% passing through China standard No. 20 sieve).

Front Street Coffee (FrontStreet Coffee) chooses a water temperature of 90℃. The higher the temperature, the more active the molecular movement of substances, but after rising to a certain temperature value, it tends to balance out. The more active the molecular movement, the higher the extraction rate. As mentioned earlier, what we pursue is not the highest value, but the most suitable value among them. While dissolving enough substances, we also need to ensure a comfortable taste, not hot enough to burn the mouth. Water temperature is usually between 83–94℃. Japan tends to use lower water temperatures because they prefer immersion extraction, which is not suitable for high temperatures. After many tests and customer feedback, Front Street Coffee (FrontStreet Coffee) believes that 90℃ water temperature is more suitable for brewing light-roasted coffee beans.

Grind size

Grind size refers to the size of coffee particles, and it affects the contact time between coffee and water. The finer the coffee powder, the more substances water can extract in the same amount of time, but if the powder is too fine, over-extraction easily occurs; conversely, the coarser the grind, the fewer substances are extracted in the same amount of time, but if the powder is too coarse, under-extraction easily occurs. Front Street Coffee (FrontStreet Coffee) recommends using 80% passing through China standard No. 20 sieve as the pour-over grind size. This is a conclusion drawn from many tests and based on taste. It should be noted that different coffee beans do not have the same grind size, so when the pour-over flavor appears abnormal, you can check whether there is a problem with the grind size.

The finer the coffee is ground, the more the surface area increases, meaning the faster the extraction speed. Front Street Coffee (FrontStreet Coffee) suggests that if you usually brew dark-roasted beans and now want to brew light-roasted beans, you can adjust the grind finer. Similarly, if you usually brew light-roasted coffee, you should grind slightly coarser when brewing dark-roasted coffee.

Front Street Coffee (FrontStreet Coffee) uses an EK43s. However, Front Street Coffee (FrontStreet Coffee) would like to add that even for grinders of the same brand, there will still be differences in grinding between them. Front Street Coffee (FrontStreet Coffee) re-sifts powder at intervals to confirm whether the grind size needs adjustment.

Pour-over coffee pouring technique

Front Street Coffee (FrontStreet Coffee) uses staged extraction, that is, three-stage pour-over pouring.

First pour: bloom (helps degassing)

During the roasting process as coffee beans change from green beans to roasted beans, they undergo a series of chemical reactions and physical changes. After roasting reaches a certain degree, a large amount of gas accumulates inside the coffee beans, most of which is carbon dioxide.

Generally speaking, the fresher the coffee beans and the closer they are to the roast date, the more bubbles usually emerge during blooming. Dark-roasted beans also release more gas during blooming than light-roasted beans. Front Street Coffee's (FrontStreet Coffee) 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, so that instability and under-extraction can be avoided during brewing.

After the gas is discharged during blooming, the coffee particles can absorb water evenly, which helps subsequent even extraction. A good bloom allows the coffee powder to degas quickly and fully, and also allows the coffee powder to fully and quickly contact water, helping the coffee powder be extracted evenly.

During pour-over coffee blooming, pay attention to the following four points:

1. Before pouring water for the bloom, first level the coffee powder.

2. During blooming, pour water gently.

3. During blooming, as little extracted liquid as possible should drip down; when too much extracted liquid appears in the server, reduce the amount of poured water, or pay attention to the grind size. (If there is too much bloom water, 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 powder. The off-flavors and astringency on the outer layer of the coffee powder also begin to dissolve out. The coffee brewed this way is both weak and has the off-flavors of over-extraction. If the bloom water is insufficient and no water drips down at all, it means the coffee powder has not absorbed enough water, and some coffee has not degassed enough, causing under-extraction.) Based on this situation, after many bloom tests, Front Street Coffee (FrontStreet Coffee) found that pouring water at twice the amount of coffee powder during blooming is more suitable.

4. Blooming time is about 30 seconds. When the expansion on the surface of the coffee powder ends, you will see shrinkage appear on the coffee surface. This means the bloom is complete and you can begin pouring. (If the bloom time is too long, the coffee easily develops bitterness and astringency; if the time is too short, soaking is insufficient, and the coffee may be under-extracted, or the flavor may not be fully expressed.) Generally speaking, the end time of blooming varies by bean, but Front Street Coffee (FrontStreet Coffee) found that this is not conducive to beginners' operation. After all, beginners emphasize standardization and ease of learning. Therefore, on the premise of ensuring the coffee beans are freshly roasted, Front Street Coffee (FrontStreet Coffee) recommends a blooming time of 30 seconds. Of course, experienced people can adjust the time themselves.

Second pour for pour-over coffee

The second pour starts from the center, with a small stream poured into the bottom of the coffee bed. In order for the penetrating force of the water stream to be concentrated, the circling range 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 water stream circles to near the filter paper, you can stop pouring.

Third pour for pour-over coffee

The coffee bed that was originally thicker at the edge of the filter paper becomes heavier after absorbing water, slides down and becomes thinner as the water level drops. When the water level drops to half, you can proceed with the third pour.

From the start of the third pour, observe the extent to which the water level drops. Likewise, start pouring from the center in circles, and do not let the water amount exceed the height of the coffee bed. At this time, you will also observe that the proportion of foam has filled the surface. In the third pour, increase the tumbling of coffee particles, so that all settled particles tumble and thereby dissolve soluble substances.

Rolling particles begin to settle when water is stopped. At this point, rely 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 water is interrupted too many times, it is equivalent to letting the coffee particles stay soaked in water, which will cause astringency and off-flavors in the final stage of coffee extraction.

Summary:

For this Front Street Colombia Huayue Night coffee bean brewed by Front Street Coffee (FrontStreet Coffee), the overall process is: use a bloom water amount that is twice the coffee powder amount, that is, 30g of water for blooming, with a blooming time of 30 seconds. Pour in a small stream in circles until 125 grams, then pause; when the water level drops and is about to expose the coffee bed, continue pouring until 225 grams and stop pouring; when the water level drops and is about to expose the coffee bed, remove the filter cup, (timing starts from the beginning of blooming) and the extraction time is 2 minutes.

Flavor of Front Street Colombia Huayue Night coffee

Rich strawberry aroma, strawberry acidity on the palate, jam-like sweetness in the middle, a slight cocoa finish, and a juicy mouthfeel.

Of course, besides the three-stage brewing technique, there are also the one-pour method, drip method, volcano pour, stirring method, and so on. Front Street Coffee (FrontStreet Coffee) suggests beginners use the three-stage pouring method to brew because this technique is suitable for light-roasted, medium-light, and medium-roasted coffee beans. The staged extraction method of three-stage pouring can clearly define the flavors of the front, middle, and back sections of the coffee, and can relatively ensure the presentation of the coffee's flavor. Below, Front Street Coffee (FrontStreet Coffee) briefly introduces several other brewing techniques and their advantages and disadvantages.

Stirring bloom method

Suitable for light-roasted coffee beans

Stirring method: during the blooming stage, use a stirring stick to stir in a cross pattern. It is also a branch of the three-stage method and is a pour-over technique developed after Matt Perger, the 2012 World Brewers Cup champion. This practice can effectively enhance the release of aromatic substances in coffee beans, amplify the flavor advantages of coffee beans, and strengthen the coffee's mouthfeel so it is not too thin.

The stirring method has very high requirements for coffee bean quality. If poorer coffee beans are used, it will amplify their undesirable flavors. In addition, the stirring bloom method is more suitable for brewing light-roasted coffee beans. In terms of grind size, a relatively fine grind is often used, which can increase the water contact area of the coffee powder and improve the extraction rate. But if the degree of stirring is not well controlled, over-extraction easily occurs.

So we also recommend pairing it with pour-over equipment known for fast extraction: the Hario v60 filter cup uses alternating long and short spiral extraction ribs, increasing the drainage speed; the cloud-like design of the hario buono pouring kettle, with its wide base, can provide stronger penetrating force for the poured water stream, allowing fine particles to remain tumbling for a longer time. This is important because when coffee particles are tumbling, the release of internal substances is paused, thus avoiding the extraction of off-flavors caused by long soaking.

Japanese drip pouring method

Suitable for medium-roasted or darker-roasted coffee beans

The drip pouring method is also called essence-style extraction: the water stream in drip pouring is weak, trying to disturb the coffee bed as little as possible, reducing convection and increasing soaking time. Coffee made with this Japanese technique has high body, high sweetness, is rich and smooth, with a distinct texture.

Because the pour-over kettle needs to dispense water drop by drop, it is suitable to choose a flat-cut wide-mouth spout or a wide-mouth gooseneck kettle. The advantage of this type of pour-over kettle is that the thickness of the water stream is highly controllable, making it more adaptable to the drip pouring method. Paired with Kono's conical filter cup, its ribs stop before reaching half the height of the filter cup. This design allows the filter paper to fully adhere to the cup wall after absorbing water, greatly limiting the degassing space. This method is more suitable for medium-roasted or darker-roasted coffee beans such as Front Street PWN Golden Mandheling and Front Street Jamaica Blue Mountain No. 1.

When starting to pour, we use drop-by-drop pouring, which increases soaking time. Under a low coffee-to-water ratio, it allows the coffee powder to fully expand without producing any off-flavors; afterward, pour with a thin stream and a thicker stream to extract the floral and fruity aromas of the coffee's front section. The whole process takes about 4–5 minutes.

One-pour brewing technique

Its meaning is that after blooming, only one uninterrupted pour is made, hence the name.

After blooming, one uninterrupted pour can keep the coffee powder continuously soaked in water, and the retained liquid fully releases the aromatic substances in the coffee powder. The water flow speed continuously increases, and before the water amount covers the filter cup, reduce the water flow. This technique mainly controls the amount of water and the flow rate. You need to know when to pour water to achieve extraction of the whole section without losing balance. An unsuitable pouring method will destroy the overall balance of the coffee.

This practice mainly maintains a mild flavor and a sense of balance. The downside is that, because the pouring technique is not well controlled, water may pass through the upper layer without coffee powder and fall through the filter paper at the edge, so the brewed coffee may include a watery taste.

Volcano brewing technique

The "volcano pour" technique originates from Japan and is suitable for dark-roasted coffee beans because these beans contain more carbon dioxide. Using the carbon dioxide in the coffee beans, through multiple blooms, the coffee powder puffs up like a volcanic eruption. The "volcano pour" mostly uses a flannel filter cloth and V60 filter cup for brewing. Because the coffee bed in the middle is thicker, water is poured at a position about the size of a one-yuan coin in the middle of the coffee powder. The first half focuses on fully extracting without disturbing the coffee bed, while the second half pours evenly to prevent over-extraction of the coffee powder in the middle and also plays a diluting role.

Advantages: the coffee has a thick mouthfeel and obvious sweet aftertaste.

Disadvantages: over-extraction in the first half and under-extraction in the second half make the coffee liquid uneven. It must be fully shaken after brewing to blend into a perfect coffee. But shaking will lower the coffee's temperature. If high-temperature extraction is used to maintain temperature, it will make the coffee dry and astringent.
