The pouring height in pour-over coffee may seem like a minor detail, but it directly affects the penetrating force of the water stream, the rate at which hot water loses heat, and the verticality of the stream, ultimately determining extraction efficiency and the flavor in the cup. Some people prefer pouring from a high position, while others habitually keep the spout close to the water surface. Both approaches have their merits, but only by understanding the effects of different heights can you adjust flexibly according to the kettle type and brewing method you use. In this article, Front Street Coffee systematically sorts out the three core effects of pouring height and offers practical advice to help you avoid common problems such as uneven extraction and over-agitation, so you can brew a more stable and delicious pour-over coffee.

The Brazilian coffee industry is facing a dual shock from drought and fires. Since the end of August, fires have continued to spread across various regions, burning large swaths of coffee plantations and forcing producers to replant, delaying the originally planned 2025 harvest to 2027. Meanwhile, the worst drought on record has swept across the country, and falling water levels in Amazonian rivers have caused congestion at southern ports, where about 1.2 million bags of coffee have piled up and been damaged, with losses reaching as high as US$300 million. Smoke has covered nearly 5 million square kilometers, affecting at least 10 states. In view of multiple factors such as fires, worsening air quality and port delays, coffee exports are expected to decline and prices will continue to rise. [more…]

When brewing pour-over coffee, do you tend to keep the spout close to the surface of the liquid, or pull out a long stream of water? Front Street has found that most enthusiasts' pouring height fluctuates between 0 and 7 centimeters. A seemingly tiny difference can profoundly change the flavor expression in the final cup through three aspects: penetration force, degree of heat loss, and the verticality of the water stream. This article will break down the actual effects of different pouring heights from a physical perspective, and combine them with Front Street's comparative experiment data to help you understand the pros and cons of high-position and low-position pouring. Whether you are a beginner pursuing stable extraction or an advanced player looking to refine your technique, you can find a pouring strategy that suits you. [more…]

Recently, a netizen posted on social media about an encounter at a Starbucks store with a middle-aged woman not wearing an apron who held up a QR code and demanded an order, even pressuring them with the remark, "Air conditioning isn't free, you know." The incident sparked heated discussion: Starbucks has long been known for its "third place" concept, allowing people to sit without making a purchase, so why did forced sales occur? Was the person involved a store partner offering extended services, or a scalper reselling coupons? Netizens engaged in fierce debate over whether Starbucks should unconditionally welcome all guests, how scalpers profit from the price difference, and whether staff collude with them. This article reconstructs the incident and the various viewpoints, exploring the boundaries between space management and consumption rules in coffee shops. [more…]

When making espresso, have you ever encountered thin crema, large bubbles floating on the surface, or a weak-tasting shot? The root cause of these problems often points to the same variable—grind size. Grinding too coarse speeds up the flow of hot water and shortens the contact time between water and coffee grounds, which not only under-extracts the flavors but also causes the force of the liquid stream to whip air into the espresso, forming large bubbles. In addition, improper storage of coffee beans leading to the loss of carbon dioxide and aromatic compounds, or switching to beans with a different roast level without recalibrating the grind, can likewise trigger similar symptoms. This article will break down these causes one by one and provide specific grind adjustment methods and formulas to help you once again extract espresso with rich crema and full-bodied flavor.

Nowadays, more and more people are paying attention to single-origin coffee, but in terms of orders at FrontStreet Coffee, espresso-based drinks still account for a larger proportion. When it comes to choosing espresso beans, what FrontStreet Coffee focuses on is [more…]

Espresso is a small amount of concentrated, pure black coffee extracted by forcing hot water under high-pressure steam rapidly through a puck of coffee grounds, with a golden layer of crema on its surface.

When grinding coffee beans, have you ever encountered powder splattering everywhere or clinging stubbornly to the grinder or portafilter? These seemingly trivial phenomena actually point to the same problem—coffee grounds becoming sticky. Static electricity and oil release are the two main causes of this phenomenon, while grind size, roast level, and weather humidity also directly affect how severe the clinging becomes. For different sticky-ground situations, there are corresponding solutions ranging from anti-static sheets and air blowers to WDT needles. Although the online trick of adding water to eliminate static works, it carries hidden risks. This article will break down the causes and solutions one by one, making the grinding process cleaner and smoother. [more…]

The surface of a freshly made latte is incredibly fine and smooth. But if we leave it sitting without drinking it, we can see the smooth, delicate surface gradually become rough and uneven. This phenomenon is called "defoaming," a process in which the milk foam continuously dissipates. Milk foam is a frothy substance formed by injecting air into milk. [more…]

The AeroPress has become the daily go-to for many coffee lovers thanks to its simple operation, clean cup, and strong adjustability. It works by adding water to steep the grounds and then applying pressure, forcing the coffee liquid through a paper filter to complete extraction. The paper filter traps fine particles that don't dissolve in water, resulting in a crisp, clean mouthfeel. This article breaks down the complete process step by step—from equipment preparation, grinding, pouring, stirring, to pressing—and shares precautions and common mistakes to avoid during use. Finally, it explains how to play with different flavor directions by adjusting variables such as the water-to-coffee ratio, grind size, number of filters, pressing time, and steeping duration. The article includes relevant recommendations and product information from Front Street Coffee for readers' reference. [more…]

Latte art is a romantic expression of a barista's skill, with white milk foam blooming into heart or leaf patterns on the surface of dark brown espresso. Latte art is divided into two types: free-pour latte art and etched latte art created after pouring. The wonder of the former lies in the pattern forming simultaneously with the pour, while the latter offers a wider range of designs because the stable foam allows for leisurely drawing. From a physics perspective, the core of latte art lies in surfactants—molecules that possess both hydrophilic and hydrophobic groups, capable of stabilizing the interface between air and liquid to form lasting foam. Milk proteins and coffee lipids act together as surfactants, enabling the two micron-scale foams to remain clearly separated for a long time after mixing, thereby allowing the pattern to persist. This article will guide you from the basic principles of surfactants to understand espresso's crema, the formation of hot milk foam, and why foam mixing rather than liquid mixing is the key to successful latte art, while also revealing the widespread applications of surfactants in daily life and industry.
