Espresso vs Pour-Over Coffee: A Tale of Two Coffee Waves

Espresso, with its rich and bold intensity, was the star of the second wave of coffee culture. In contrast, pour-over coffee, revealing various aromas through its smooth texture, has become the leading lady of the third coffee wave.

French King Clement VIII once described coffee as: "Although it is the devil's drink, it is delicious and pleasant." Looking back at historical records, coffee gradually integrated into people's lives after World War II before spreading throughout the world. Since then, coffee has escaped its obscure fate, not only opening a new chapter for espresso and coffee shops but also successfully driving the popularity of pour-over and specialty coffee in the early 2000s, adding more complete palate-teasing options for coffee enthusiasts.

Espresso Coffee

The "es" in espresso actually comes from the English "ex," meaning fast and convenient. Espresso coffee beans are called "House Blend"—what we commonly hear as blended/formula coffee. As the name suggests, these are coffee beans made from a mixture of beans from multiple regions. Using blended coffee beans helps balance flavors and stabilize taste.

To ensure the quality of the final brew, espresso is typically made by grinding coffee beans to a fine consistency using a professional grinder before brewing, allowing espresso to complete extraction in a short time.

Authentic espresso is made by passing near-boiling high-pressure hot water (92-94°C, 9 bar atmospheric pressure, 20-30 second extraction time) through finely ground, evenly tamped coffee grounds to create approximately 30ml of beverage. The surface carries a thick, dense layer of coffee oil foam called Crema, with colors leaning toward golden yellow and brown. Nowadays, the color also varies depending on the roast level of the coffee.

Traditional Italians place great importance on espresso culture and quality. For this reason, the Italian National Coffee Institute provides official certification for espresso extraction parameters, making the brewing process data-transparent and helping to more completely preserve the traditional flavors of espresso.

Pour-Over Coffee

Pour-over coffee involves the barista controlling various parameters such as water temperature, flow rate, water volume, and coffee grind size, completing the extraction by pouring water steadily over the coffee grounds. The extraction principle of pour-over coffee relies on three physical mechanisms between water and coffee grounds: (soaking and blooming, dissolution, diffusion, and ratio adjustment). If any one of these factors is adjusted, it will affect the final flavor of the entire cup of coffee, which is why pour-over coffee is so meticulous about every aspect of the brewing process.

The selection of beans for pour-over coffee is mainly determined by factors such as origin, flavor profile, characteristics, processing method, and roasting approach. While not limited to single-origin coffee beans or blended/formula coffee beans, pour-over coffee typically prioritizes single-origin beans. Unless a single flavor is too intense or there's a preference for a special flavor profile, blending is used to balance the taste.

Espresso Flavor Profile

Because espresso has a very intense flavor, many people add sugar or milk to balance the bitterness, which in turn has sparked a trend with espresso as the base. Fancy espresso drinks combine with syrups, cream, spices, and various seasonings to create multi-layered coffee flavors with diverse taste profiles. Drinks like Con Panna, Macchiato, Caramel Macchiato, Cappuccino, Latte, Mocha, and Americano all belong to the espresso family!

Pour-Over Coffee Flavor Profile

Single-origin coffee beans each come from a single region, single variety, and even come with complete production records. To fully preserve the unique flavors of that region, the roasting technique and control of roast level become particularly important!

Generally, the longer the roasting time, the higher the richness, with more noticeable milky, caramel, and chocolate aromas. Conversely, shorter roasting times highlight acidity, making bright fruit aromas more prominent. For pour-over coffee bean selection, there are no restrictions on light, medium, medium-dark, or dark roasts—it usually depends on the drinker's preference.

Coffee as a Life Companion

Wave after wave of coffee culture has made us all witnesses to this artistic beverage. Whether you're a pour-over coffee enthusiast, an espresso follower, or simply a busy person needing caffeine to refresh your mind, coffee plays an extremely influential role in our lives.

Although taste preferences are very subjective and no formula can determine which coffee is "best," as long as drinking brings comfort and pleasure, both pour-over coffee and espresso can become the most wonderful flavor in the drinker's heart!
