Kang Shiwei, who runs the Connie compound Coffee Restaurant in Bad, Taoyuan, fell in love with the rich aroma of coffee more than 20 years ago, and has since fallen into the charming world of coffee. In order to taste coffee from different countries and tell whether coffee is good or bad, eight years ago, the teacher learned the skills of choosing coffee beans, roasting, brewing, and so on. In his eyes, coffee is an unfathomable art.

"good coffee beans don't produce oil, they breathe when they brew!" Kang Shiwei, who likes to share coffee knowledge, says that coffee beans have a shelf life of only seven days for deep roasting and 45 days for shallow roasting.

The larger the light area, the faster the oxidation, and if the coffee powder expands when brewing, it means it is fresh enough.

He says that not only red wine can be paired with food, but coffee can also be used as well. the important thing is that it can also help metabolism and digestion. "one cup can last for three days." the sharp weapon to relax, reflect, and put aside your troubles is coffee.

The more you know about coffee beans, you will know the amorous feelings and national character of coffee bean producing countries. Central and South America represents enthusiasm, Asians represent vitality, while Africa has a taste full of hope for life.

Kang Shiwei's fascination with coffee attracts coffee lovers from all over the province. While tasting coffee and listening to him describe stories related to coffee, every day is the beginning of happiness. It is no wonder that he compares coffee to a kind of life. He said lightly: "just live, not celebrate holidays." "
