Coffee Tips: Learn some small things about coffee

The origin of coffee

Coffee is a beverage made from ground coffee beans that originated in Ethiopia, Africa. According to legend, in the 9th century AD, a shepherd found that his sheep were full of energy after eating a red fruit. So he tried the fruit and found that it could keep people awake and refreshed. This is the origin of coffee.

Classification of coffee beans

Coffee beans can be divided into several different types according to their origin and processing methods. The most common ones are Arabica and Robusta. Arabica beans are produced in smaller quantities, but are of higher quality and have a more delicate taste; Robusta beans are produced in larger quantities and are suitable for making strong-tasting espresso.

Effect of grinding degree on taste

Different grinds have an impact on the flavor of the final brewed coffee. Coarse grinds are good for drip coffee because their grooves allow for better contact with the water; medium grinds are good for French press coffee because they release more flavor during the steeping process; and fine grinds are good for espresso because they produce a stronger flavor through high pressure brewing.

Brewing time and temperature

Brewing time and temperature are also important factors that affect the taste of coffee. Generally speaking, longer brewing time will make the coffee bitter, while shorter brewing time will make it taste darker. At the same time, water temperature that is too high or too low will have an adverse effect on the taste. The best brewing temperature is generally around 90℃.

Preserving Coffee Beans

In order to maintain the freshness and taste of coffee beans, there are a few things to note when storing them. First, squeeze out the air in the unopened package and keep it sealed as much as possible; second, store it in a cool, dry and dark place; finally, try to avoid opening the package frequently to prevent air and moisture from entering.

Caffeine content

Caffeine is an alkaloid substance in coffee that has a refreshing effect. Different types and roasting degrees of coffee beans contain different amounts of caffeine. Generally speaking, Robusta beans contain more caffeine than Arabica beans; and lightly roasted coffee beans contain more caffeine than darkly roasted ones.

Drink in moderation

Although drinking coffee in moderation can bring some benefits, such as refreshing and increasing attention, excessive intake may cause palpitations, insomnia and other problems. Everyone has different tolerance to caffeine, so please control your intake according to your own situation.

Health related

In addition to providing spiritual enjoyment, moderate coffee consumption is also associated with some health benefits. For example, it is believed to reduce the risk of certain cancers, Parkinson's disease and type 2 diabetes. However, excessive coffee consumption may increase the risk of cardiovascular disease. Please drink in moderation according to your own situation.
