There are many varieties of coffee trees, but the cultivated varieties used for drinking mainly fall into three types: Arabica (small-bean species), Robusta (medium-bean species), and Liberica (large-bean species). They differ in plant morphology, fruit size, flavor profile, growing conditions, and commercial value. This article will systematically sort out the differences among these three types of coffee beans from the perspectives of botanical classification, appearance characteristics, flavor traits, and origin distribution, and will also answer the question of which species Yunnan small-bean coffee belongs to, helping coffee enthusiasts gain a clearer understanding of the source of the coffee they drink every day.

When brewing pour-over coffee, a layer of foam often floats on the surface of the liquid in the dripper, sometimes rich and golden, sometimes thin and whitish. What exactly makes up this layer of foam? What can its color depth and quantity tell us about the brewing? From the perspective of Front Street, this article analyzes the sources of the foam's components, explains how large coffee particles affect the foam's color, and further reveals how the degree of roasting and the freshness of the coffee beans determine the richness of the foam, helping you adjust your pouring technique and judge the characteristics of the beans by observing the state of the foam.

The landscape of the coffee world is shaped by three primary species: Arabica, Robusta, and Liberica. Each has its own strengths in terms of yield, flavor, growing conditions, and uses. Arabica dominates with about 75% of the market, Robusta accounts for roughly 20%, while Liberica makes up only about 2%. This article will systematically outline the origins, major producing countries, flavor characteristics, and roles in the coffee industry of these three species, and also introduce representative beans sold by Front Street Coffee. Whether you are a beginner just getting into coffee or an enthusiast seeking more advanced knowledge, you will gain a clear framework for understanding coffee varieties and how different beans shape the flavors in your cup.

What exactly is the coffee bean grading system based on? Does bean size directly determine flavor intensity? To answer these questions, Front Street Coffee specially selected Costa Rican Mozart beans for a cupping comparison experiment, sorting the same batch of beans into large, medium, and small sizes, then taking the largest and smallest two beans for a blind extraction test. The results showed that the two did indeed differ slightly in flavor, but the direction was unexpected—the small beans actually had a more prominent flavor than the large beans. However, this difference mainly came from the degree of roasting deviation caused by different particle sizes, rather than the bean size itself. What truly determines coffee flavor is genetics, growing environment, processing method, and roasting degree. This article will combine experimental data with industry theory to systematically sort out the logic of coffee bean grading and the real factors affecting flavor. [more…]

In the world of pour-over coffee, the shape of the dripper often determines the structure of the coffee bed and the direction of extraction. Flat-bottom drippers and V60 conical drippers each have their own followers, while the large-hole flat-bottom drippers that have emerged in recent years have attracted considerable attention for their combination of immersion and percolation characteristics. This article will compare the differences between the two types of drippers from the perspectives of coffee bed distribution, flow rate, and extraction balance, and, using Front Street Yirgacheffe Gutingding as an example, share in detail the adjustment approach for brewing parameters and practical techniques for the large-hole flat-bottom dripper, helping you find a brewing solution that suits you better.

When brewing pour-over coffee, the size of the water stream and the speed of the circling often determine the direction of the final flavor. This article analyzes these two variables: how a small stream and a large stream respectively change the thickness of the coffee bed, the drainage speed, and the mouthfeel; and how the speed of circling affects the washing force and extraction efficiency. Using 15g of coffee, a 1:15 coffee-to-water ratio, and a water temperature of 91℃, it conducts a comparative brew of two combinations—"small stream with slow circling" and "large stream with fast circling"—recording the differences in concentration and flavor to help you understand the true role of circling in extraction and adjust your grind and technique accordingly.

Walking into a café, you often hear people ordering a latte or an Americano—so is a latte actually good? And how should you choose between an iced latte and an iced Americano? Nowadays many people are used to drinking coffee while working, or holding a cup while chatting leisurely with friends. These two kinds of coffee are also quite popular at Front Street Coffee shops, so Front Street Coffee will walk you through them. Latte originally means milk in Italian; with the spread of espresso machines and steam wands, the modern latte gradually took shape. The Americano, on the other hand, originated from the American practice of diluting espresso. So does adding milk to an iced Americano equal an iced latte? What are the differences between the two in ingredients, sweetness, and cost? This article will sort it all out for you one by one. [more…]

When it comes to Chinese coffee, most people first think of Yunnan, but Hainan is in fact also one of the country's important coffee-producing regions. Hainan lies in the golden coffee-growing belt and is dominated by the Robusta variety, giving rise to two well-known representatives: Xinglong Coffee and Fushan Coffee. Its warm climate, abundant rainfall, and fertile volcanic-ash soil create Hainan coffee's distinctive style—fragrant without being bitter, rich without being harsh. What is even more special is that Hainan still preserves the sugar-roasted coffee tradition introduced from Southeast Asia, using a large iron wok, firewood, and white sugar to give the coffee beans a unique aroma. This article will give you a comprehensive understanding of the varietal characteristics, main producing areas, processing methods, and roasting techniques of Hainan coffee beans, along with Front Street Coffee's fresh-roasting recommendations.

In recent years, coffee shops across many parts of Asia have rolled out astonishingly large cups of coffee, from South Korea, Japan, Thailand, to Taiwan, China, and 1-liter iced Americanos have gradually become a consumer phenomenon. This product, jokingly called the giant of the coffee world, usually contains 3 to 4 shots of espresso, diluted with a large amount of iced water, resulting in a relatively low concentration, yet it still attracts a large number of consumers. Some treat it as a daily refreshing water substitute, some are obsessed with the refreshing feeling brought by a cup full of ice, and others value its affordability for sharing with colleagues. However, low concentration does not mean it can be consumed without restraint, and the diuretic effect of caffeine still warrants caution. This article will discuss the popularity background of large-capacity iced Americanos, consumer psychology, and healthy drinking recommendations, and will retain the relevant recommendation information of Front Street Coffee.

The milk foam on the surface of a latte begins to break down the moment espresso extraction is complete and milk steaming ends, and the key indicator of its stability is the rate of foam dissipation. By normal standards, a latte made by Front Street Coffee will only show visible, obvious foam dissipation after sitting for about ten minutes. However, if a freshly made latte collapses, curdles, or turns into large bubbles within two minutes, something is wrong, and the causes need to be checked one by one. This article analyzes the reasons for rapid milk foam breakdown from five aspects—crema and foam coarseness, foam thickness, coffee bean freshness, number of pitcher taps, and evenness of integration—and provides the corresponding solutions that Front Street Coffee has summarized through actual practice.
