Coffee knowledge revealed: varieties, roasting, brewing techniques, all in one place!

Coffee Varieties

Coffee is a beverage made from coffee beans, which come in several varieties. The most common varieties include Arabica and Robusta. Arabica beans are generally considered high quality, with lower acidity and bitterness, and floral and fruity flavors. Robusta beans are stronger, contain more caffeine, and have higher acidity and bitterness.

The impact of roasting on coffee taste

Roasting is the process of heating green coffee beans to varying degrees to change their flavor profile. Generally speaking, light roasts preserve the original flavor and accentuate certain nuances; medium roasts produce a balanced taste, slight acidity, and sweetness; while dark roasts bring out rich, bitter, cocoa, or woody notes.

Brewing tips

Brewing is the process of bringing crushed or ground coffee beans into contact with hot water to extract the coffee. Here are some common brewing techniques:

1. Drip brewing: Put the ground coffee into the filter paper, then slowly pour in the pre-heated water.

2. French press: Put the coarse powder into the pot, add appropriate amount of boiling water, wait for a while and then press the filter.

3. Espresso Machine: Uses high pressure to force hot water through tightly packed coffee grounds to create a rich, strong espresso.

summary

Understanding different varieties, roasts and brewing techniques is essential to tasting the best cup of coffee. No matter what flavor and taste you like, you can choose the right variety, roast and brewing method to make your ideal cup of coffee according to your preferences.
