Coffee knowledge points: varieties, roasting, brewing methods, a comprehensive interpretation of the charm of coffee

Coffee Varieties

Coffee is a beverage made from coffee beans, which come in several varieties. The two most common varieties are Arabica and Robusta. Arabica beans are generally considered high-quality and high-value beans, with lower caffeine content and a more complex, aromatic flavor. Robusta beans have a higher caffeine content and a more bitter, strong flavor.

The impact of roasting on coffee taste

Roasting is the process of heating green beans to a specific temperature to change their color, aroma and flavor characteristics. Different degrees of roasting produce coffee of different types and flavor intensities.

- Light roast: At this degree, the beans retain most of their original flavor and have characteristics such as bright acidity, light and light with sour fruit or floral aromas.

- Medium/medium-dark roast: At this level, the beans begin to become darker and more intense in flavor. The acidity gradually decreases, replaced by rich sweetness and perceptible flavors such as chocolate, nuts or caramel.

- Dark roast: At this degree, the beans become very dark and the surface oils are fully released. The caffeine content is low, the taste is rich and bitter, and there is a distinct caramel or roasted wood aroma.

Coffee experience brought by different brewing methods

Brewing methods refer to the process of bringing coffee into contact with water to extract its flavor and characteristics. Here are a few common brewing methods:

- Drip brewing: This is one of the most common and easiest brewing methods. Coffee is made by pouring boiling water over a dripper filled with filter paper and coffee grounds. This method produces a clean and balanced taste, medium acidity and a smooth mouthfeel.

- French press: Use a French press to make a rich, full-bodied cup of coffee. Mix the ground coffee with hot water, then use a press to push the grounds to the bottom of the pot. This method retains more oils and flavors, producing a stronger, richer-tasting cup of coffee.

- Espresso: Espresso is a high-pressure brewing method that produces a strong and full-bodied small cup of coffee by passing high-temperature and high-pressure water through compacted coffee powder. This method can extract a large amount of flavor compounds and produce characteristics such as bitterness and caramel aroma.
