Can blended coffee beans be used for pour-over extraction?
Blended coffee beans can be used for pour-over, but the result differs from espresso. Pour-over usually favors light to medium roasted single-origin beans, with water dripping through the grounds at atmospheric pressure to show the coffee's original flavor, while espresso mostly uses darker roasted blends pushed through at 9 atmospheres to make a concentrated liquid.
The two also differ in caffeine and in how the drink is finished: espresso is combined with milk or water for cappuccino, latte or americano. A Moka Pot sits between the methods, using steam pressure at home, so a blend meant for espresso can work there too, though the grind and dose need adjusting.
Many people just entering the world of coffee are curious: what exactly is the difference between pour-over and espresso? In fact, from bean selection and extraction pressure to caffeine content, the two take completely different paths. Pour-over favors light-to-medium roasted single-origin beans, using gentle dripping under atmospheric pressure to showcase the coffee's true flavor; espresso, on the other hand, mostly uses dark-roasted blends, extracted under 9 atmospheres of pressure to obtain a rich coffee liquid, which then combines with milk or water to create classic drinks such as cappuccino, latte, and americano. This article will compare the two in detail across three dimensions—coffee beans, brewing methods, and caffeine content—and provide Front Street Coffee's practical steps for espresso and pour-over respectively, helping you consistently recreate a good cup of coffee at home.
Coffee's popularity in China has been rising year by year, even showing signs of catching up with fast-moving tea drinks like milk tea, though consumer groups have their own preferences. When it comes to coffee, pour-over and espresso are the two major categories you can't avoid. Pour-over is most often paired with single-origin beans; it presents coffee's unadorned side—not rough, not concealed, not simple—and can be said to be another interpretation of coffee. Overall, pour-over's extraction style leans gentle—of course, this is relative to espresso.
On a solitary afternoon, coffee, a book, and a soft chair together make a simple contentment. The beauty of pour-over single-origin coffee lies in being able to watch the entire extraction process with your own eyes, watching the coffee drip down drop by drop, revealing its most authentic form. By comparison, espresso must complete extraction under 9 atmospheres of pressure—this is the second reason I call pour-over gentle. Actually, espresso also has heart-stirring moments; you just may not have tasted them yet. The third reason may be that pour-over more easily allows people who originally didn't like coffee to accept coffee and enjoy its original taste. Admittedly, espresso is more "idiot-proof" to make and more easily accepted by the masses, but perhaps it is precisely pour-over's maverick beauty that has attracted so many followers.
Let's now look at the specific differences between pour-over coffee and espresso.
1. Different coffee beans
Pour-over coffee
Pour-over usually uses single-origin coffee beans as raw material, with roast levels mostly concentrated in light and medium roasts, though some people prefer to use dark-roasted beans for pour-over.
Espresso
Espresso generally blends different single-origin beans together—that is, blended coffee beans—widely used to make espresso drinks such as cappuccino, americano, and latte. These beans are generally roasted darker so as to pair with milk and hot water. Making espresso requires grinding with a professional espresso grinder, which is also the foundation and key to producing a high-quality espresso.
2. Different brewing methods
Pour-over coffee
Pour-over mostly uses a dripper and completes extraction under normal atmospheric pressure; if you switch to a moka pot, AeroPress, or similar device, the extraction pressure can also reach 3 bar (three atmospheres).
Espresso
Espresso relies on an espresso machine for extraction; the machine's pressure brings the extraction state to 9 bar (9 atmospheres), and the puck in the portafilter basket must withstand 133 kilograms of pressure, thereby releasing a large amount of coffee substances, including some flavor compounds that are difficult to dissolve under normal pressure. Therefore espresso has a thicker mouthfeel and is suitable for adding milk to make a latte, or diluting with water to make an americano.
3. Different caffeine content
Given the same dose and grind size, caffeine is a water-soluble substance, and the longer the brewing time, the more is released. Pour-over brewing time is usually 1–3 minutes, while espresso takes only 20–30 seconds, so with the same dose and grind size, pour-over actually has a higher caffeine content. From this one can also infer that long-extraction coffees like ice drip and cold brew will have caffeine content much higher than other methods.
As you can see, the coffee liquid from pour-over and Espresso differs enormously in concentration. Once milk is added to single-origin coffee, the coffee's own aroma and flavor are masked by the milk, so coffee shops generally do not recommend adding milk to pour-over.
How to make espresso
Many coffee enthusiasts unwittingly accumulate a pile of equipment at home, and those enamored with espresso even get an espresso machine early on, ready to extract it themselves. Using Front Street Coffee's in-store espresso output as a reference, here is a brief explanation of how to make an Espresso.
Front Street Coffee's store uses a commercial single-group "Lelit Bianca," which can adjust extraction by changing pressure, with maximum pressure reaching 11 bar. A home coffee machine only needs to reach 9 bar pressure to meet the needs of extraction and milk frothing, paired with an espresso grinder.
Front Street Coffee uses a double basket capacity, with a dose of about 18–20 grams, using 20 grams of coffee powder for output. Usually the ratio of coffee powder to coffee liquid is between 1:1.5 and 1:2.5; Front Street Coffee's extraction ratio is 1:2, meaning 20 grams of coffee powder extracts 40 grams of coffee liquid. Time is related to the flow rate of the coffee powder; generally a single extraction is controlled at 20–35 seconds, because within 20 seconds the coffee often tastes thin, while over 35 seconds it easily over-extracts and develops a burnt bitter taste. Front Street Coffee's espresso mostly falls within the 28–30 second range.
Front Street Coffee first wipes the basket dry, turns on the grinder, grinds out the amount for a double shot of coffee powder, places it on the electronic scale and adjusts up or down to reach 20 grams. Next, use a tool to distribute the grounds evenly, tamp the coffee puck firmly to ensure more stable extraction. Then turn on the extraction switch to release water, moistening the group head while washing away stuck coffee grounds; gently and slowly lock the portafilter onto the group head, and begin pulling down the brew lever to extract. When the electronic scale shows 40 grams of coffee liquid extracted and the time is about 30 seconds, you can pull down the extraction switch. Pour the coffee liquid into an Espresso cup and enjoy.
Espresso's taste and mouthfeel are related to the coffee beans used. Front Street Coffee's in-store espresso uses Front Street Sunflower Warm Sun Blend, composed of Honduras Sherry coffee and Ethiopia natural Red Cherry in a 7:3 blend. Made into Espresso, it has rich crema, a very obvious whisky aroma, an acidity of vanilla cookies and berries on the entry, a solid flavor, and after drinking, the entire mouth is filled with various aromas.
Espresso can also be diluted with water—that is, the americano commonly seen on menus, full of fresh fragrance; adding milk makes a latte, presenting the sweet deliciousness of chocolate and cream.
How to make pour-over coffee
To make pour-over coffee at home, you need the following equipment: gooseneck kettle, dripper, server, grinder, filter paper, electronic scale, thermometer. Here Yirgacheffe is a medium-light roasted high-altitude coffee bean; Front Street Coffee hopes to extract more abundant aromatic substances, so it chooses a grind size with an 80% pass rate through a No. 20 standard sieve, corresponding to a grinder setting of 10 on the store's EK43s; in addition, light-roasted coffee needs a higher water temperature to stimulate aroma, so 91–93°C is used, with a resin V60 01 dripper for extraction.
On online media you can see various pour-over pouring techniques, such as one-pour, three-stage, 4:6 method, and so on; different techniques will cause differences in the flavor expression of the coffee in the cup. Based on past brewing experience, Front Street Coffee recommends that beginners just starting out use three-stage pouring. Three-stage extraction helps more fully dissolve flavor substances during extraction, increasing the layers of mouthfeel, while avoiding overly long immersion that causes over-extraction.
If using 15 grams of coffee powder, a 1:15 coffee-to-water ratio, 225 ml total water, the three-stage water amounts are divided into: 30 ml, 95 ml, 100 ml, and the weight on the electronic scale shows: 30 g, 125 g, 225 g.
Fold the filter paper and fit it snugly against the dripper, wet the filter paper with a small amount of water while making them fit better, and pour out the water in the lower server. Then pour in the coffee powder and tap lightly to distribute the coffee bed evenly. For the first stage, gently pour in 30 grams of water for blooming, with a bloom time of 30 seconds; for the second stage, pour in water to about 125 grams, circling outward evenly and steadily. Then wait for the coffee liquid to drop; when it has dropped by half, pour the final stage of water to 225 grams, and wait for all the coffee to drip through; the total extraction time is generally about 2 minutes.
The reason everyone loves pour-over coffee so much is that we can actively explore the coffee's extracted flavor expression: adjusting the brewing method according to different coffee bean varieties and roast levels, carefully selecting brewing vessels to feel the different appearances brought by different extraction methods, and regulating factors such as grind size, temperature, flow rate, and pouring technique to adjust extraction. Every step can bring a different taste and olfactory experience—this is the charm of pour-over coffee.
