Coffee knowledge revealed: varieties, roasting, brewing techniques and health benefits

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 higher quality, better tasting, and more expensive. They are characterized by their aromatic aroma, moderate acidity, and mild taste. Robusta, on the other hand, has a stronger bitter flavor and a full-bodied taste.

The impact of roasting on coffee

Roasting is the process of treating green coffee beans with heat to change their flavor characteristics. Different degrees of roasting produce different flavor types of coffee. Light roasting retains the original flavor and brings a bright, high acidity cup with fruity or floral notes; medium to medium-dark roasting adds dark tones such as sweetness, nuts or chocolate; dark roasting produces special styles such as bitterness, cocoa or carbonization.

Brewing tips

Brewing is the process of bringing ground coffee into contact with water to extract the coffee flavor. Here are some common brewing methods and techniques:

- Drip method: Using a paper filter and a dripper, slowly pour hot water over the ground coffee, allowing it to flow through the filter.

- French Press: Place the ground coffee in a French Press, add boiling water and press with the piston.

- Espresso: Use an espresso machine to make rich and strong espresso.

- Cold brew method: Mix coarsely ground coffee powder with cold boiled water and let it sit for several hours to several days before filtering to obtain cold brew liquid.

Health Benefits

Moderate coffee consumption may provide several health benefits:

- Refreshing: Because it contains a certain amount of caffeine, moderate drinking can increase alertness, concentration and reaction speed.

- Antioxidant effect: The antioxidants in coffee can help reduce damage caused by free radicals and play a role in preventing chronic diseases.

- Improve athletic performance: Caffeine can stimulate the nervous system, increase muscle contraction and endurance, and thus improve athletic performance.

- Reduced risk of certain diseases: Moderate coffee consumption has been linked to a lower risk of heart disease, stroke, type 2 diabetes and certain cancers.
