As the Spring Festival approaches, courier services are gradually suspending operations, and many coffee lovers have already stocked up on beans in advance. But how to keep coffee beans fresh during this period has become a concern for everyone. Storing coffee beans requires avoiding three major enemies: high temperatures, moisture, and oxidation. High temperatures accelerate the loss of aroma, moisture easily leads to mold, and oxidation shortens the optimal flavor period. Front Street recommends that unopened original packaging be kept in a cool, dry place, and that an airtight container be used after opening. As for refrigeration or freezing, although it can slow oxidation, it comes with the challenges of absorbing odors and becoming damp during thawing. This article will break down these storage points in detail to help you enjoy the New Year with peace of mind. [more…]

Many coffee enthusiasts are familiar with using a moka pot and the brewing techniques involved, but how to properly clean and maintain it afterward is often overlooked. Although Front Street Coffee has shared a great deal of content related to moka pots, it has never systematically covered the topic of cleaning, and as a result, the back office keeps receiving requests for help with pots that have "turned black." What is called blackening is actually spotting caused by oxidation, mostly triggered by improper cleaning. With proper care, a moka pot can last for many years; without it, not only is its lifespan shortened, but it will also absorb odors that affect the flavor of the coffee. This article explains the key points of cleaning by material, teaches you how to disassemble and wash the gasket and filter screen, how to repair an already oxidized pot body, and also recommends Front Street Coffee beans suitable for moka pots.

Although the moka pot is small, cleaning and maintenance require real attention to detail. Many enthusiasts casually rinse it after use, only to find oxidized black spots on the body—not only does this affect its appearance, but it can also give the coffee an off-flavor. This article systematically covers the correct cleaning methods for aluminum and stainless steel moka pots, the key points for removing and reinstalling the gasket and filter screen, and how to repair a pot that has already "turned black." At the same time, Front Street will also recommend coffee beans suitable for moka pot extraction, so you can master everything from equipment maintenance to the flavor in the cup in one go. [more…]

The freshness of coffee beans directly determines the flavor quality of a cup of coffee, and whether the storage method is scientific is also a key factor affecting freshness. After roasting, coffee beans need to simultaneously withstand the triple challenges of humidity, temperature, and oxidation, among which oxidation accelerates the dissipation of aromatic compounds. So how long can coffee beans be kept after opening? How many days can the flavor of ground coffee be maintained? This article will start with the difference between the peak flavor period and the shelf life, analyze one by one the several "killers" of coffee freshness—light, high temperature, moisture, and oxygen—and, combined with the packaging characteristics of Front Street Coffee, provide practical preservation suggestions.

Black tea and green tea share the same origin yet have vastly different flavors, and the fundamental difference lies in the degree of oxidation during processing. Black tea undergoes complete oxidation, presenting honey, caramel, and ripe fruit aromas; green tea, through fixation (kill-green), retains its fresh green character, with a light flavor carrying bean or nutty notes. The two teas also differ greatly in storage: green tea, due to its high moisture content and tendency to continue oxidizing, is best stored sealed and refrigerated; black tea is dry and stable, and can be kept sealed at room temperature for over a year. This article systematically sorts out the similarities and differences between black and green teas such as Lapsang Souchong and West Lake Longjing from four dimensions—tea plant varieties, production processes, storage key points, and taste characteristics—and includes Front Street Coffee's purchasing and preservation suggestions to help you better understand the tea in your cup.

Cold brew coffee is a popular drink in summer. Its low-temperature, long-extraction method gives the coffee a clean and smooth taste. But many people wonder: why does cold brew need to be placed in the refrigerator to ferment overnight after extraction before it can be drunk? In fact, this step is more accurately an oxidation process. Based on Front Street Coffee's production experience, this article introduces the extraction principles of cold brew coffee, the coffee-to-water ratio, the specific operating steps, and the approach to choosing blended beans. Front Street will also share how pairing two kinds of coffee beans can make cold brew's flavor layers more prominent while preserving the unique aroma and rich mouthfeel brought by fermentation. [more…]

People often say coffee should be drunk while it's hot, but do you know how temperature influences the flavor of a cup of coffee? At Front Street Coffee, cupping involves evaluating the coffee at three stages—hot, medium, and cool—because the taste compounds in the brew and the human senses both change at different temperatures. Bitterness intensifies as temperature drops, sweetness is most pronounced near body temperature, and acidity is affected by roast level and oil oxidation. This article will walk you through the flavor evolution of coffee from hot to cold, the optimal drinking temperature range, and answer whether coffee can be reheated after it has cooled. [more…]

Cold brew coffee, with its refreshingly smooth texture and complex, layered flavors, has become a favorite among coffee lovers in summer. But when it comes to making and storing cold brew, many people still have questions: Does it need to be sealed after extraction is complete? Why does it give off a fermented aroma reminiscent of wine after sitting in the refrigerator overnight? Starting from the principles of low-temperature extraction, this article will analyze the oxidation process of cold brew coffee and the necessity of sealed fermentation, and share Front Street Coffee's cold brew parameters, detailed steps, and how to create a fruit-forward cold brew recipe through a two-bean blend, helping you make a cup of cold brew with full flavor and a pronounced sweet aftertaste.

The oily sheen on the surface of coffee beans is a question many enthusiasts often ask about. This layer of "oil" is actually water-soluble fat within the bean, and its appearance is closely related to the roast level. Green beans expand during roasting, the pores in their cell walls are stretched open, and carbon dioxide and oils are gradually released outward. Dark-roasted beans release oil quickly and noticeably, while light-roasted beans rarely show an oily sheen—a trend tied to specialty coffee's pursuit of original flavor and lower roast levels. Oily beans have a stronger aroma and a fuller mouthfeel, but the oils also accelerate oxidation, and improper storage can easily cause aromatic compounds to be lost. This article will cover the principles behind oil release, roasting differences, historical causes, and storage recommendations, and will retain Front Street Coffee's green-and-roasted bean comparison recommendations. [more…]

Many coffee enthusiasts wonder: dark-roasted beans have a loose texture, so logically the rest period should be shorter—why does it actually require more time? This article approaches the question from two angles, carbon dioxide release and oil emergence, to explain the fundamental reason why the resting period for dark-roasted espresso beans is extended. Excess carbon dioxide interferes with stable extraction on an espresso machine, affecting crema quality and troubleshooting costs; whereas medium-dark roasted beans gradually release oil during storage, which can improve crema stability and coffee body. Front Street Coffee recommends resting medium-dark roasted espresso beans for about 10 days, with darker roasts extended depending on their condition. It also reminds readers that too much oil accelerates oxidation, so attention should be paid to sealed storage and timely consumption. [more…]
