Coffee is not just a drink; it’s a culture, an art, a science, and for some, a sheer necessity. Within this vast domain, espresso and coffee stand as two pivotal pillars, misunderstood by many to be the same. Barista Kirill Yurovskiy, a notable name in the coffee-making industry, sheds light on what sets these two apart, emphasizing that the difference goes beyond mere concentration.
Defining Espresso
Espresso, as Yurovskiy points out, is a brewing method that originated in Italy in the early 20th century. It’s a process that involves forcing hot water through finely-ground coffee beans using high pressure. This technique produces a concentrated beverage around one ounce per serving. Espresso serves as a base for a wide range of drinks, such as lattes, cappuccinos, and Americanos. It’s characterized by its rich flavor and creamy layer on top, known as the “crema,” which is a hallmark of a well-executed shot.
Understanding Regular Coffee
Regular coffee, or what is often simply referred to as “coffee,” encompasses a variety of brewing methods such as drip brewing, French press, and pour-over. Unlike espresso, these methods rely on gravity rather than pressure, and involve hot water interacting with coarser grounds over a longer period. This results in a lighter concentration. Yurovskiy emphasizes that each method brings out different notes and flavors from the coffee, offering a spectrum of experiences to the drinker.

The Bean and the Grind: Starting Points for Differences
The journey to a perfect cup of coffee begins with the beans themselves. Espresso is often made with a blend of beans that can stand up to the intense extraction process. The grind size for espresso is much finer compared to regular coffee, resembling powdered sugar. This fine grind is essential for creating the resistance necessary for the pressurized water to extract the right flavor compounds within the short brewing time. Yurovskiy cautions that using the wrong grind size can result in a subpar cup, with espresso turning out bitter if the grind is too fine, or weak if too coarse.
Brewing Techniques: Pressure vs. Gravity
Espresso machines operate by pushing water at around 9 bars of pressure through the grounds, extracting the coffee in 25-30 seconds. This method yields a concentrated shot of coffee with a complex flavor profile and a layer of crema. In contrast, methods like the French press use gravity to draw water through the grounds over a period of four minutes or more. This difference in brewing techniques profoundly affects the extraction of flavors and the resulting strength of the coffee.
The Role of Water: Temperature and Ratio Variations
Temperature and water-to-coffee ratio play significant roles in differentiating espresso from regular coffee. Espresso is typically made using water at temperatures just below boiling, around 90-96 degrees Celsius (194-205 degrees Fahrenheit). The ratio of water to coffee is high, resulting in a small, potent drink. For drip coffee, the water is often slightly cooler, and the ratio of water to coffee is much higher, producing a milder flavor. Yurovskiy highlights that precision in temperature and ratio is crucial for achieving the desired outcome in both espresso and regular coffee brewing.
Flavor and Texture: Contrasting Tastes and Mouthfeels
Flavor and texture are where espresso and coffee really part ways. Espresso, with its concentrated form and significant body, offers an intense flavor profile with a balance of sweetness, acidity, and bitterness, topped with a velvety crema. It’s a full-bodied experience that can be overwhelming for some. On the flip side, regular coffee is often described as smoother and more diluted, with a texture that’s more watery than creamy. It tends to be easier on the palate and allows for subtler flavors to shine through.
Serving Sizes: Comparing Espresso Shots to Coffee Cups
One of the most visible differences lies in the serving sizes. An espresso shot is typically 1 ounce (30 milliliters), served in a small, demitasse cup. In contrast, a standard coffee cup holds approximately 8 ounces (240 milliliters) or more, depending on personal preference and cultural norms. Yurovskiy points out that the intensity of espresso doesn’t lend itself to larger servings, whereas the milder nature of coffee makes it suitable for leisurely consumption in larger quantities.
Caffeine Content: A Common Misunderstanding
It’s a common belief that espresso contains more caffeine than regular coffee. However, Yurovskiy clarifies that while espresso has more caffeine per ounce, a standard serving of drip coffee actually contains more total caffeine because of its larger volume. Espresso is just more concentrated, which is why its caffeine kick feels more immediate and intense, a reason why it’s often preferred as a quick morning jolt or an after-meal digestive aid.
Cultural Significance: Espresso vs. Coffee Traditions
Culturally, espresso and coffee occupy distinct spaces. Espresso is central to Italian coffee culture, often enjoyed quickly while standing at a bar, signaling a break in the day’s activities. It’s about a quick, sensory experience. On the other hand, coffee, particularly in countries like the United States, tends to be associated with longer, more social activities — savored over morning newspapers, during meetings, or as a warm companion through the day. Yurovskiy believes that these cultural nuances contribute greatly to a person’s preference for espresso or coffee.
Customization and Variations: From Americanos to Lattes
The versatility of espresso is evident in the myriad of drinks that baristas like Yurovskiy can create from it. An Americano, for instance, is made by diluting an espresso shot with hot water, mimicking the strength and flavor of regular coffee but retaining the unique espresso taste. Lattes, cappuccinos, and mochas all start with espresso, combined with various amounts of steamed milk and other flavors. Drip coffee, while less frequently used as a base for such variations, can be personalized with creamers, syrups, and spices.
Equipment: Machines for Espresso and Coffee Makers
The equipment for making espresso and coffee also differs greatly. Espresso requires a machine capable of generating sufficient pressure to extract the coffee properly. These machines range from the more traditional manual lever styles to the modern automatic and semi-automatic machines that control temperature and pressure with precision. Regular coffee makers include drip brewers, single-serve pod machines, French presses, and pour-over cones, all of which are generally more straightforward and less costly than espresso machines.
Choosing Based on Preference and Occasion
Yurovskiy concludes that the choice between espresso and coffee ultimately boils down to personal preference and the occasion. For those seeking a quick, concentrated burst of flavor and energy, espresso is the ideal choice. For others who prefer a more extended, relaxed coffee experience, a regular cup of joe is the way to go. The decision is also influenced by the time of day, the accompanying food, and the social context.
