By deeply understanding the types of coffee beans, roasting methods and brewing techniques, it reveals how to taste these basic flavors in coffee and how to blend them according to personal taste preferences. The article emphasizes that tasting coffee is not only a sensory experience, but also a reflection of a life attitude.

In the busy urban life, coffee has become a daily drink for many people. Everyone has different preferences for coffee. Some people love its unique bitterness, while others like its rich aroma. But do you really understand the four basic flavors of coffee: sour, sweet, bitter, and salty? Let's explore the story behind this.

Let's talk about sourness. You may be surprised, how can coffee have sourness? The sourness in coffee mainly comes from the chemical reaction of coffee beans during the roasting process. Moderate roasting will make the coffee beans produce a bright sour taste, adding a refreshing feeling to the coffee. Different roasting degrees will bring different sourness, from the bright sourness of light roasting to the deep sourness of dark roasting, all of which are manifestations of the unique charm of coffee.

Next is the sweetness. Many people may ignore the sweetness in coffee because we usually add sugar to neutralize the bitterness of coffee, but in fact, coffee naturally contains sugar. These sugars react with amino acids during the roasting process of coffee beans to produce what we call caramel flavor, bringing a unique sweetness to coffee. This sweetness blends with the bitterness of coffee to make the coffee taste mellower.

Speaking of bitterness, this is the most well-known taste of coffee. Bitterness is the iconic characteristic of coffee, but did you know that bitterness is actually produced by the combined action of multiple compounds in coffee beans. Caffeine and theophylline are the main sources of bitterness, which bring a deep sweetness to coffee. Different coffee beans and different roasting methods will affect the presentation of bitterness, making each cup of coffee have its own unique flavor.

Let's talk about saltiness. You may find it strange that coffee can have a salty taste. Saltiness plays a balancing role in coffee, just like seasoning in cooking. Saltiness adds a sense of balance to the flavor combination of coffee, making other flavors more prominent. This subtle saltiness comes from the minerals and moisture in the coffee beans. They interact with each other during the roasting process, adding a light salty and fresh feeling to the coffee.

To truly taste these four flavors, we need to pay attention to the type of coffee beans, roasting method and brewing techniques. Different coffee beans will have different flavors. For example, Arabica coffee beans have a bright sour taste and a soft taste, while Robusta coffee beans have a deeper sourness and a stronger taste. The influence of roasting methods should not be underestimated. From light roasting to dark roasting, each stage will affect the presentation of sourness, sweetness and bitterness. The water temperature, time and whether to use a filter during brewing will affect the final presentation of the coffee's taste and mouthfeel.

In the process of exploring the four basic flavors of coffee, we can't help but marvel at the charm contained in these tiny coffee beans. Every subtle change will affect the final taste presentation, and each flavor represents the unique charm of coffee. Perhaps it is because of these different flavors and feelings that coffee has become an indispensable part of people's lives around the world. In the days to come, we can continue to explore more about the mysteries of coffee and feel the different experiences that the four basic flavors bring us.

Whether it is the fresh sour taste, the mellow sweet taste, the aftertaste of bitterness or the balance of saltiness, every flavor is worth our careful savoring. Let us immerse ourselves in the world of coffee and feel its endless charm!
