The core knowledge you need to know about coffee

The origin of coffee

Coffee is a drink made from ground coffee beans that originated in Africa. According to legend, coffee was discovered by a shepherd named Kaldi in the 9th century AD. He noticed that his sheep became unusually active after eating a red fruit. So he tried eating the fruit and found that it could keep people awake and energetic.

Coffee Bean Processing

Of course, before we can enjoy delicious coffee, we need to process the coffee beans. The first step is picking and peeling. The most mature, red or yellow fruits are picked by hand and the outer pulp is removed by machine.

Next comes the fermentation and washing process. The peeled beans are soaked in water for 24-48 hours for fermentation, and stirred regularly to ensure uniformity.

Then they are dried and roasted. The beans, which have been fermented and dried and have lost most of their remaining moisture, are put into the oven for roasting. The roasting time and temperature will affect the flavor of the coffee beans.

Coffee classification

Coffee can be divided into several different types based on the type of coffee beans and how they are processed. The two most common are Arabica and Robusta.

Arabica coffee generally has higher acidity, aroma and taste, while Robusta is more bitter and contains more caffeine. In addition, there are some special types of coffee, such as Blue Mountain, Columbia, etc.

Grinding and Brewing

Before we can enjoy a delicious cup of coffee, we need to grind the beans that have been freshly roasted and stored in appropriate conditions (protected from light, sealed). This ensures the best flavor.

Depending on the different brewing methods (drip, French press, espresso, etc.), you need to choose the appropriate coarseness to adjust the extraction time and flavor intensity.

Keep it fresh

In order to keep the coffee fresh, we need to pay attention to the following points. The first is the storage method. It is best to store the coffee beans in a light-proof, sealed and low-temperature environment.

The second is the grinding time. It is best to grind the beans before brewing. This can avoid caffeine oxidation and flavor loss.

In addition, choosing the right brewing ratio and time is also the key to keeping the coffee fresh. Too strong or too weak will affect the taste.

Taste and Appreciate

Tasting a cup of quality coffee requires careful attention to the subtle differences. From the appearance, observe its color, transparency, sediment and other characteristics.

Then you smell the wine to see if it has floral or fruity notes, caramel or chocolate, or other complex flavors. The final step is to taste it, rubbing the flavors on your tongue and assessing their balance and richness.
