Introduction:In Guangdong, people commonly refer to pure coffee without sugar or milk as “zhaai coffee” (齋咖啡), which is essentially what we usually call black coffee. But did you know that zhaai coffee actually includes various brewing methods? From Americano to pour over and even cold drip, which one is your idea of “pure”? This article delves into the definition of Cantonese-style zhaai coffee, compares it with Americano and pour over, introduces the characteristics and preparation details of iced Americano, and also explores the actual health impacts and considerations of black coffee.

In the Guangdong region, people often call pure coffee without sugar or milk “zhaai coffee,” which is generally what we refer to as black coffee. The term “zhaai” in Cantonese means plain or without additives, so zhaai coffee encompasses various types of pure coffee liquid including Americano, pour over, cold drip, and even coffee brewed with devices such as moka pots or French presses. Among them, iced Americano is especially popular in summer and among fitness enthusiasts due to its refreshing taste and low calorie content.

So, what specific types does the Cantonese term “zhaai coffee” refer to?

“Zhaai” means plain and without additives, so zhaai coffee is pure coffee without the addition of milk, sugar, or other flavoring substances. Whether it's an Americano extracted using an espresso machine, or pure coffee liquid made by pour over, cold drip, or immersion methods—as long as nothing extra is added—it can be classified as zhaai coffee. Among these, “bing zhaaifei” (ice zhaai coffee), which is what most people know as iced Americano, is the most popular form.

So, what unique flavor profile does iced Americano have?

Iced Americano is actually very simple in composition, requiring only three ingredients: espresso, ice cubes, and water. Precisely because there’s no interference from milk or sugar, it can more directly showcase the original aroma and taste of the coffee beans, which also makes the quality of the espresso itself more critical. One particular shop uses their own roasted blend bean called “Sunflower Warm Sun Blend.” This blend consists of 70% Honduran Sherry coffee and 30% Yirgacheffe natural red cherry. The Sherry beans bring out distinct whiskey-like aromas, vanilla, and a creamy richness, while the red cherry provides tropical fruit notes and a slight fermentation sensation. The overall aroma is layered and rich, with a smooth mouthfeel that isn’t harsh.

In terms of preparation, the shop typically grinds the coffee beans to a suitable coarseness for espresso, then extracts at a 1:2 coffee-to-water ratio—meaning 20 grams of coffee grounds yield 40 grams of espresso. This is then mixed with ice cubes and water, usually adding around 120 grams of ice and 120 grams of room temperature water. It’s recommended to drink it before the ice fully melts, as that’s when the flavor is most vibrant. This iced Americano offers a refreshing sweet-and-sour taste, making it easily enjoyable even for those not accustomed to black coffee.

Why is iced Americano so popular?

The popularity of Americano coffee stems not only from its moderate concentration, which is just right for most people and has a relatively approachable taste, but also from its potential health benefits. Moderate consumption can aid digestion, reduce bloating, and in the hot climate of Guangdong, iced Americano is an excellent choice for cooling down and quenching thirst, making it an ideal summer beverage. More importantly, it’s extremely low in calories, and drinking it about an hour before exercise may help boost metabolism and assist with fat burning, which is why it’s favored by many fitness enthusiasts.

However, it’s important to note that these potential benefits apply only to pure Americano coffee. If sugar syrups, condensed milk, or various creamers are added, not only will the calorie intake increase significantly, but it may also offset the health benefits of the coffee itself.

So, what is the long-term health impact of drinking Americano coffee?

According to medical research, moderate consumption of black coffee (such as Americano) generally does not have adverse effects on health, nor does it increase the risk of specific cancers. On the contrary, it may offer benefits such as antioxidant properties and metabolic enhancement. However, it is recommended to limit daily intake to within 3 cups, which is considered safe and beneficial for most people, though this still depends on individual constitution. If you often experience insomnia, palpitations, or gastrointestinal discomfort after drinking, you should reduce your intake or opt for decaffeinated alternatives.

In summary, Cantonese-style zhaai coffee is not just plain black coffee without additives—it encompasses multiple brewing methods and flavor profiles. Whether you prefer the refreshment of iced Americano or the delicate layers of pour over, you can find your own choice within the world of zhaai coffee. While enjoying coffee, remember to follow the principle of moderation to balance taste and health.
