Americano vs Latte: Caffeine and Bean Choice

Pour-over and espresso differ in bean choice, roast level, and extraction. Pour-over usually uses single-origin beans, light to medium roasts, normal pressure, and a longer contact time, which dissolves relatively more caffeine. Espresso uses blended beans, darker roasts, and about 9 atmospheres of pressure for a fast, thick shot that pairs well with milk.

The common question of whether espresso blend beans work for pour-over has a practical answer: they can be brewed that way, though the cup will taste different from a single-origin pour-over. The same distinction shows up in americano vs latte, where dilution or milk changes the drink far more than the extraction method itself.

There are significant differences between pour-over coffee and espresso in terms of preparation methods, coffee bean selection, and caffeine content. Pour-over mostly uses single-origin beans, primarily light to medium roasts, extracted at normal pressure with a longer brewing time, resulting in relatively higher caffeine dissolution; espresso relies on blended beans, dark roasted, rapidly extracted at 9 atmospheres of pressure, with a thick mouthfeel, suitable for pairing with milk. This article will compare the two across three dimensions—bean selection, preparation methods, and caffeine content—and provide a detailed introduction to Front Street's in-store Espresso preparation process and the hands-on steps for pour-over coffee, helping enthusiasts understand the essential differences between these two extraction methods, while also answering the common question of whether espresso blend beans are suitable for pour-over.

Coffee's popularity in China has been rising year by year, even showing signs of overtaking fast-moving beverages like milk tea, though different consumer groups naturally have different preferences. When it comes to coffee, pour-over and espresso are two major categories that cannot be avoided. Pour-over coffee is most often paired with single-origin beans; it presents a kind of unadorned beauty—not crude, not concealing, not monotonous—arguably another exquisite expression of coffee. Overall, pour-over's extraction style is relatively gentle, though of course this is in comparison with espresso.

Sitting alone in the afternoon, a cup of coffee, a book, a soft chair—these simple elements piece together a plain kind of happiness. The beauty of pour-over single-origin coffee lies in being able to witness the entire process from pouring water to extraction to the drip-drip falling, which is coffee in its most authentic form. By contrast, espresso relies on nine atmospheres of pressure for extraction—this is my second reason for calling pour-over gentle. Actually, espresso also has heart-stirring moments, it's just that you may not have experienced them, and this perhaps is the third advantage of single-origin coffee—it more easily allows people who originally didn't like coffee to accept coffee and enjoy its original flavors. It cannot be denied that espresso preparation is more "idiot-proof" and more easily accepted by the masses, but perhaps it is precisely the maverick beauty of pour-over that has attracted so many followers.

Let's take a look at what differences actually exist between pour-over coffee and espresso.

1. Different coffee beans

Pour-over coffee Pour-over typically uses single-origin coffee beans as the raw material, with light and medium roasts being the most common, though of course some people prefer to use dark-roasted beans for pour-over.

Espresso Espresso generally blends multiple single-origin beans together, known as blended coffee beans, widely used for making cappuccino, Americano, latte, and other espresso drinks. These blended beans are generally roasted darker to pair well with milk and hot water. Making espresso requires a professional espresso grinder for grinding—this is also the foundation and key to producing a high-quality cup of espresso.

2. Different preparation methods Pour-over coffee Pour-over coffee is mostly done with the aid of a dripper, meaning extraction occurs under normal atmospheric pressure. If using a moka pot or AeroPress, extraction pressure can reach 3 bar (three atmospheres).

Espresso Espresso is extracted through an espresso machine; the machine's pressure brings extraction to 9 bar (9 atmospheres), and the puck inside the portafilter bears approximately 133 kilograms of pressure, forcing the coffee to release a large amount of 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 Under the same conditions of dose and grind size, since caffeine is a water-soluble substance, the longer the extraction time, the more caffeine is dissolved. Pour-over coffee's brewing time is typically 1 to 3 minutes, while espresso extraction takes only 20 to 30 seconds, so under the same dose and grind size, pour-over coffee will have a higher caffeine content. From this it can be inferred that cold drip coffee, cold brew coffee, and other long-extraction coffees will have caffeine content much higher than other coffees.

You can see that the coffee liquid brewed by pour-over and Espresso differs greatly in concentration. After adding milk to single-origin coffee, the coffee's own aroma and flavors are masked by the milk, so coffee shops generally do not recommend adding milk to pour-over coffee.

How to make espresso

Many coffee enthusiasts have unknowingly accumulated various coffee equipment at home, and those obsessed with espresso have even stocked up on espresso machines, ready to try extraction themselves. Front Street here uses in-store espresso production as a reference to briefly explain how to make an Espresso.

The coffee machine used at Front Street's store is 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 of pressure to meet the needs of extraction and milk frothing, paired with an espresso grinder.

Front Street uses a double-shot basket capacity, with a dose of approximately 18 to 20 grams; Front Street uses 20 grams of coffee powder when producing. Typically the ratio of coffee grounds to coffee liquid is between 1:1.5 and 1:2.5; Front Street'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; generally a single extraction is controlled between 20 and 35 seconds, because within 20 seconds the coffee taste is usually thin, and over 35 seconds it tends to over-extract and develop a burnt bitter taste. Front Street's espresso mostly completes within 28 to 30 seconds.

Front Street first wipes the portafilter basket dry, turns on the grinder, grinds out a double shot's worth of coffee powder, places it on an electronic scale to adjust up or down to reach 20 grams. Then 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, wetting the group head while washing away stuck coffee grounds, gently lock the portafilter onto the group head, and begin pulling the shot. When the electronic scale shows 40 grams of coffee liquid extracted, at 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. The espresso produced at Front Street's store uses Front Street Sunflower Warm Sun Blend. It is a 7:3 blend of Honduras Sherry coffee and Ethiopia natural Red Cherry; made into Espresso, it has rich crema, a very pronounced whisky aroma, with vanilla biscuit and berry acidity on the palate, solid flavors, and after drinking, the entire mouth is filled with various aromas.

Espresso can also be diluted with water, which is the commonly seen Americano on menus, fragrant and refreshing; add milk and it becomes a latte, presenting the sweet and delicious taste of chocolate and cream.

How to make pour-over coffee

To make pour-over coffee at home, we need the following equipment: gooseneck kettle, dripper, server, grinder, filter paper, electronic scale, thermometer. Here the Yirgacheffe is a high-altitude coffee bean with a medium-light roast; Front Street hopes to extract more rich aromatic substances, so we choose a grind size with 80% passing through a No. 20 standard sieve, corresponding to a setting of 10 on the EK43s grinder used in-store; additionally, light-roasted coffee needs higher water temperature to stimulate aromas, so we use 91–93°C, and use a resin V60 01 dripper for extraction.

On online media, we can see various pour-over pouring techniques, such as one-pour, three-stage, 4:6 method, etc. Various techniques can bring out different flavor expressions in the cup. Based on past brewing experience, Front Street recommends that beginners just starting out use the three-stage pouring method. Three-stage extraction helps more fully dissolve flavor compounds during extraction, adding layers to the mouthfeel, while avoiding overly long steeping that causes over-extraction.

If using 15 grams of coffee powder, 1:15 coffee-to-water ratio, 225ml total water, the three-stage water amounts are divided as: 30ml, 95ml, 100ml, and the weight shown on the electronic scale would be: 30g, 125g, 225g.

Fold the filter paper and fit it snugly against the dripper, wet the filter paper with a small amount of water while making them adhere better, pour out the water in the server. Then pour in the coffee powder, tap lightly to distribute the coffee bed evenly. For the first stage, gently pour 30 grams of water for blooming, with a blooming time of 30 seconds; for the second stage, pour to about 125 grams of water, evenly and steadily circling outward. Then wait for the coffee liquid to drop; when it has dropped by half, pour the final stage of water to 225 grams. After all the coffee has dripped through, the total extraction time is generally about 2 minutes.

The reason everyone loves pour-over coffee so much is that when we actively explore the extraction flavor expression of coffee, adjusting the brewing method according to different coffee bean varieties and roast levels, carefully selecting brewing vessels to experience the different appearances coffee takes under different extraction methods, and regulating grind size, temperature, flow rate, pouring technique, and other factors to adjust coffee extraction—every step can bring a different taste and olfactory experience. This is the charm of pour-over coffee.
