In the world of pour-over coffee, the choice of filter paper directly affects the flavor in the cup. Filter paper offers outstanding filtration, delivering a clean and bright mouthfeel, but for this very reason it traps some of the coffee oils, making the aroma and body slightly inferior to tools such as metal mesh filters and cloth filters. From the perspective of Front Street, this article takes a deep dive into the composition of coffee oils and crema, explains how the filtration medium affects coffee's aroma and body, and, through a comparative brewing experiment between filter paper and non-woven filter paper, demonstrates the specific differences in flavor performance between the two. If you are struggling to decide which filtration tool to choose, or want to understand the characteristics of non-woven filter paper, this article will provide you with a clear reference. [more…]

"Liquor color" is originally a professional term in tea evaluation, used to describe the color and visual characteristics of brewed tea, and is also one of the criteria for judging tea quality. So for coffee, can liquor color also serve as a basis for evaluating quality? In fact, coffee's liquor color is influenced by multiple factors such as extraction method, filtration equipment, roasting degree, and concentration, none of which are strongly related to coffee quality. Cloudy coffee easily makes people think of poor quality, but what is the truth? Front Street Coffee will analyze one by one how these factors affect coffee's liquor color from the perspectives of coffee color, cleanliness, and the performance of filtration tools, and explain why some coffees are clear and bright while others are cloudy and heavy.

Milk-brewed coffee, which uses milk instead of water to brew coffee by the cold brew method, makes it easy to produce a cup of rich, flavorful milk coffee, and has recently been highly recommended by bloggers. But many enthusiasts still have quite a few misunderstandings and questions about making it. In this article, Front Street will focus on three core points about milk-brewed coffee: first, emphasize food safety—milk easily breeds bacteria, so attention must be paid to sterilizing containers, making small batches, and drinking it promptly; second, explain the choice of coffee beans—because milk extraction efficiency is low, it is recommended to give priority to beans with strong flavors or dark roasts, such as Front Street PWN Golden Mandheling, Front Street Strawberry Candy · Geisha Blend, etc.; finally, analyze the filtration problem—filter paper is too slow, so tools such as tea bags can be used instead, but cleanliness will decline somewhat. The full text aims to help everyone avoid pitfalls and make a delicious cup of milk-brewed coffee. [more…]

On the surface of an espresso, that layer of golden-brown foam is often regarded as a sign of extraction quality, but in essence it is a structure formed when carbon dioxide bubbles are wrapped by the water-soluble fats inside the coffee beans. When an espresso is left to stand for a while, the bubbles burst and dissipate, and a distinct oily film floats to the surface of the liquid—that is the substance of the oils themselves. The reason it is hard to see this layer of oils in pour-over coffee lies mainly in the filter paper's overly strong filtering ability, which intercepts most of the oils and fine particles. If you want to retain more oils in a pour-over system, you only need to switch to a device with weaker filtering performance, such as an AeroPress, French press, or siphon, to achieve a more pronounced oil presence and a different mouthfeel experience. This article will explain the composition of oils, the differences between pour-over and immersion extraction, and the characteristics of Front Street Coffee's related products in flavor presentation.

Cold brew coffee, with its advantages of simple operation and low cost, has become the preferred way for many coffee enthusiasts to make iced drinks at home. However, many people find in practice that a layer of oil slick unexpectedly floats on the surface of a finished pot of cold brew, and they can't help worrying that the coffee has gone bad or the container was not cleaned properly. Where exactly does this layer of oil come from? In fact, its cause is completely different from that of the Crema on the surface of espresso. This article will focus on the low-temperature extraction principle of cold brew, explain the phenomenon of oil condensation, and share the complete operational details from filter selection to secondary filtration, helping you make a cup of cold brew coffee with a clear mouthfeel and full flavor.

Many coffee enthusiasts notice that the same beans taste stronger and more pronounced when brewed as an Americano on an espresso machine than when made with a pour-over. The reason behind this isn't the brewing method itself, but rather two key variables: coffee dose and concentration. Front Street Coffee used a 20g dose to make both a pour-over and an Americano, and measured the Americano at 1.95% concentration versus 1.54% for the pour-over—a significant difference. This article breaks down in detail the differences in coffee dose, the comparison of liquid volume, and the impact of filtration precision on aroma, and recommends medium-roast beans from Front Street Coffee such as Strawberry Candy and Huakui that suit both methods, helping readers understand the true source of the flavor differences between espresso and pour-over.

Can pour-over coffee have oils? The answer is yes, but it requires a different approach. The crema of espresso is essentially oil encapsulating carbon dioxide, and it is the lipids in the coffee beans themselves that truly give coffee its rich body and aromatic boost. Because pour-over uses a filter paper with excessively strong filtration, it is nearly impossible to retain oils. To change this, you simply need to switch to a device with slightly weaker filtration performance, such as a flannel cloth or non-woven filter paper, and Front Street has clear recommendations on this. This article will explain the mechanism by which lipids work and compare in detail the pros and cons of different filters and the key adjustment points, to help you achieve a richer mouthfeel in pour-over.

In recent years, global coffee consumption markets have shown steadily growing interest in cold brew coffee, yet considerable confusion still surrounds this category. Cold brew is essentially an extraction method, not a specific form of cold drink—it refers to the process of slowly dissolving flavor molecules from coffee grounds using low-temperature water as the medium. Compared with hot-water brewing, cold brew's extraction efficiency is greatly reduced due to the constraints of water temperature, so it is necessary to control factors such as time, bean condition, stirring technique, and filtration precision in order to obtain a cup of iced coffee with balanced acidity and sweetness and a clean mouthfeel. Front Street Coffee, combining in-store practical experience with comparative experiments, has sorted out four key variables that affect cold brew flavor, along with operation suggestions that can be replicated at home, for coffee enthusiasts to check item by item.
