A complete analysis of the basics of coffee

Coffee is a popular drink that we can enjoy at home or in a coffee shop. However, for many people, the basics of coffee may not be enough. This article will give you a detailed introduction to the basics of coffee.

1. Coffee Beans

The first thing to understand is coffee beans. Most commercially available coffee is made from two main types of beans: Arabica and Robusta. Arabica beans are generally considered to be of higher quality, better tasting, and contain less caffeine. Robusta beans have a higher concentration and bitterness and contain more caffeine.

In addition, when buying, you need to pay attention to whether to choose whole beans or ground and packaged beans. Whole beans stay fresher longer, but you need to use a grinder to process them yourself; while already ground beans are more convenient, but they are easy to lose freshness.

2. Coffee roasting

Coffee beans undergo chemical changes during the roasting process, resulting in different flavors and aromas. Generally speaking, coffee beans that are roasted lightly retain more of their original flavor and have a more sour taste, while beans that are roasted deeply have a richer and bitter taste.

Different degrees of roasting also affect the caffeine content. There isn’t much difference between lighter colors (like visible to the naked eye) and medium colors (like semi-urban or full urban), but darker colors (like French or Italian) can result in higher caffeine levels.

3. Coffee brewing method

Knowing the basics of brewing is key to becoming a competent home barista. Here are a few common and easy-to-follow brewing methods:

• Drip filter: Place coarsely crushed particles on filter paper and pour hot water. Wait for the water to pass through the filter paper and then enjoy.
• French Press: Place the coarsely ground coffee granules in a container, add hot water and stir well. Then press down on the filter and pour out the coffee.
• Espresso machine: Place finely ground particles into the machine and use high pressure to get a strong cup of espresso.

These methods have their own characteristics and applicable scenarios. You can choose the appropriate brewing method according to your personal taste and needs.

4. Storage and preservation

To preserve the freshness and flavor of your coffee beans, you need to store them correctly after purchasing them. Here are a few key points:

• Protect from air, moisture and sunlight: Store beans in airtight containers away from direct sunlight and moisture.
• Avoid high temperatures: Do not expose beans to high temperatures, such as near a stove or on a windowsill in the sun.
• Avoid long storage periods: Try to use your beans within two weeks of purchase to maintain optimal flavor.

If you purchase ground coffee, it is recommended to use it as soon as possible to avoid losing freshness. For whole beans, you can grind the required amount each time as needed.

5. Coffee tasting tips

Coffee tasting is a combination of art and skill. Here are a few tips to help you better taste coffee:

• Smell identification: Hold the cup of coffee close to your nose and take a deep breath. Note whether there are fruity, nutty or other aromas.
• Savor: Take a sip of coffee and let it rest on your tongue for a moment. Notice its characteristics like acidity, sweetness, bitterness, and mouthfeel.
• Compare different types: Taste different types of coffee or coffees from different origins at the same time to compare their flavors and characteristics.

With constant experimentation and practice, you will gradually develop a sensitivity to coffee and be able to better appreciate its nuances.
