Here are 5 things you must know about coffee to improve your coffee taste in one minute.

Many people seem to be obsessed with coffee and are willing to spend a lot of time queuing up in famous coffee chains, but do they really understand coffee? Some basic questions about coffee are too embarrassing to ask the store clerk. Let's learn about the five things you must know about coffee and improve your coffee taste in one minute.

1. Light roast vs dark roast

According to the American grading system, coffee beans can be roasted in eight stages from light to dark. The taste of coffee mainly depends on the degree of roasting. Generally, the darker the roasting, the stronger the bitterness, and the lower the roasting, the higher the sourness. The depth of roasting mainly depends on the characteristics of the raw beans, personal preferences and other factors.

2. Arabica vs Robusta

In terms of varieties, coffee trees are mainly divided into two types: Arabica and Robusta. Arabica coffee is mostly produced in tropical areas of South America such as central Brazil. The beans are smaller, the caffeine content is lower, and the price is higher. Robusta is produced in central, western and eastern Africa, Madagascar Island, and Indonesia in Asia. The beans are larger, the caffeine content is about twice that of Arabica, and the price is lower.

ps: About 75% of the world's coffee is Arabica, but only 10% is coffee that can be used in high-end coffee shops.

3. Espresso vs. Drip Coffee

Espresso is made by forcing hot water under high pressure through a handful of tightly packed, fine coffee powder, which has a higher caffeine concentration and contains crema. Drip coffee, on the other hand, is made by forcing boiling water through coarsely ground coffee powder, which has a lower caffeine concentration and contains almost no crema, making it more suitable for large-scale drinking.

4. Latte vs. Cappuccino

Latte and cappuccino are both milk coffees, the main difference is the different ratios of espresso, milk and milk foam. To make a cappuccino, the amount of espresso, hot milk and milk foam should be the same (1:1:1), while the amount of hot milk for latte is more (1:2:1). Latte tastes more dense and delicate, while cappuccino is slightly dry.

5. Latte vs. Café Au Lait

Simply put, latte is made with espresso and steamed milk, while café au lait is made with drip coffee and steamed milk.
