For a long time, caffeine has often been seen as the culprit behind coffee's unhealthy reputation, leading many people to switch to decaf. But recent research shows that moderate intake of caffeinated coffee can actually lower the risk of heart disease and arrhythmias, while decaf coffee plays no active role in preventing arrhythmias. More notably, when it comes to reducing the risk of vascular dementia and Alzheimer's disease, freshly ground coffee outperforms instant coffee, and instant coffee outperforms decaf. Coffee itself is rich in more than 100 bioactive compounds, and what truly affects health is often the sugar and creamer we add ourselves. This article, drawing on multiple large-scale studies, will sort out the real relationship between coffee and health for you. [more…]

Coffee bugs, in the previous few issues we learned about the origin and spread of coffee, so where does the coffee we drink today come from? Next, follow Little One to explore coffee-producing regions around the world~ Currently there are 53 major coffee-producing regions globally, all distributed within the Coffee Belt 『25°N～30°S』. Based on the spread timeline of specialty coffee and the flavors of the origins, we can roughly group these regions into three major categories: Old World old-fashioned flavor category, New World improved flavor category, and Oceanic island flavor category. In this issue, Gain Knowledge will first present the Old World coffee introduction~ Countries that already had Arabica varieties before the 17th century are called the "Old World," led by Ethiopia (Ethopia), with Yemen (Yemen) and India (India) as followers. These three ancient coffee countries retain the most diverse Arabica bean gene pool and traditional natural processing method. Their coffee flavor spectrum is broad and complex, with the greatest amplitude: from rough earthy, woody, leathery, medicinal, and fermented tofu off-flavors, to charming jasmine, cinnamon, cardamom, clove, pine and fir, mint, lemon, citrus, berry, apricot, smoked plum, chocolate... thousands of aromas and flavors, both good and bad, constructing an old-fashioned flavor spectrum that makes people love and hate it at the same time. Ethiopia has the world's most diverse coffee cultivation system and a complex ancient superior gene pool, plus diverse processing methods including natural, washed, and semi-washed, presenting complex and changeable flavors. It can be said that the "flavor spectra" of coffee-producing regions around the world can mostly be tasted here, reflecting Ethiopia's all-embracing "king's flavor."

Today, a coffee cup and saucer are mostly just a coaster and a decorative item. But in Europe before the eighteenth century, the saucer was the "star" of coffee drinking. In 1640, the Dutch brought coffee from Mocha in Yemen to the Netherlands, and from there it spread throughout Europe, quickly making coffee drinking a fashion among the upper classes. At that time, Europe had not yet mastered porcelain-making technology and could only import thin, light porcelain cups from China—yet these cups had no handles, making the freshly brewed coffee too hot to hold. So people poured the coffee into the saucer to cool it, then sipped it the way modern cuppers do. It was not until the eighteenth century, when the Germans mastered porcelain production and handled porcelain cups became widespread, that the habit of drinking coffee from the saucer gradually faded away. This history has also been recorded in many paintings, so let's look together at the coffee stories in those still lifes and figure paintings. [more…]

Raf coffee is a distinctive coffee drink originating from Russia that has gradually gained public attention in recent years for its smooth and sweet taste. Its creation is quite dramatic—in the late 1990s, a regular customer named Rafael at a Moscow café, tired of traditional coffee, asked a barista to craft him a new drink that was both mild and layered. After repeated experimentation, three baristas finally created this coffee named after him. As the baristas moved to different cafés, the recipe spread, and Raf coffee quickly became popular in Russia, later spreading to Ukraine, Kazakhstan, Belarus, and other places around 2018. Traditional Raf coffee uses espresso, cream, vanilla sugar, and white sugar as ingredients. The key is that all ingredients are mixed together, then whipped and heated at the same time, resulting in a flavor somewhere between a latte and a dessert. This article will walk you through its history and provide specific preparation steps recommended by Front Street Coffee. [more…]
