A 500mL bottle of Dongpeng Special Drink contains as much as 66.5 grams of sugar, equivalent to eating about 15 sugar cubes. A third-party testing agency's evaluation of 12 functional drinks on the market shows that Dongpeng Special Drink far outpaces the others in sugar content, even surpassing carbonated beverages known for being high in sugar. In response to this result, Dongpeng said its formula has been approved by the state and recommended drinking only one bottle per day. High sugar intake is closely linked to obesity, chronic diseases, and even accelerated aging, yet the sugar in functional drinks is difficult to completely remove. When late-night overtime workers treat Dongpeng Special Drink as a "life-renewing elixir," do they realize they are being "stabbed in the back" by high sugar? This article will take an in-depth look at this test report and explore the high-sugar dilemma of functional drinks. [more…]

In the extraction process of pour-over coffee, how well the filter paper fits the dripper directly affects the final cup quality. Many enthusiasts find that if the filter paper does not sit tightly against the dripper wall, even the best dripper cannot deliver its intended design advantages. Take the currently popular V60 dripper as an example: its unique spiral rib structure can hardly function when the filter paper fails to fit properly. Therefore, before formal brewing, the step of wetting the filter paper is especially critical—it not only removes the papery taste and dust from the filter paper itself, but is also the core operation for making the filter paper fit tightly against the inner wall of the dripper. Starting from the structural function of the dripper, this article will explain in detail the key points of folding and fitting the filter paper, and share Front Street Coffee's experience in actual operation, to help everyone improve the stability and flavor performance of pour-over extraction.

When making espresso, a puck sticking to the group head is an embarrassing situation many baristas dread most. Behind this is actually a close relationship with the espresso machine's pressure relief function—after extracting the coffee, the machine needs to release the residual pressure in the portafilter basket, otherwise removing the handle could cause the machine to explode. So why exactly does the puck get stuck? And how does the pressure relief valve work? Front Street Coffee will explain these issues clearly in one go, from principles to practical operation, helping you understand and avoid this kind of "work nightmare." [more…]

Chagee once launched a free custom cup sticker printing campaign, allowing users to upload images to create milk tea cup stickers.

The brand may also bear joint liability for failing to establish an effective review mechanism. This article sorts out the entire incident and analyzes the legal issues and responsibilities of all parties involved. [more…]

From the back garden of King Louis XIV's Palace of Versailles in 18th-century France, to its spread to the Caribbean island of Martinique, and then to its introduction and promotion in the Saint Andrew region of Jamaica, the rise of Blue Mountain coffee is inseparable from one key institution—the Jamaica Coffee Industry Board (CIB).

Caffeine is a much-discussed active component of coffee. It dissolves easily in hot water but poorly in cold water, stimulates the central nervous system, sharpens the mind, and also has cardiotonic and diuretic effects. A cup of coffee typically contains 60-65 milligrams of caffeine, but excessive intake may cause discomfort such as tinnitus and palpitations. Black coffee is considered the way of drinking that best preserves the beneficial components, offering multiple functions such as refreshing the mind, stimulating the appetite, promoting urination, activating blood circulation, relieving asthma, and removing odors. Light roasts have a higher caffeine content, which helps with weight loss, while the antioxidant effects of black coffee help fight cancer and aging. A healthy adult can metabolize 500-600 milligrams of caffeine per day, roughly equivalent to 5 cups of coffee, while pregnant women need to reduce their intake. This article will systematically analyze the mechanisms of caffeine's effects, its pros and cons, suitable populations, and scientific drinking methods, and recommend quality products from Front Street Coffee.

The Clever Dripper stands out among pour-over equipment, having gained international recognition and been selected as designated gear by many specialty coffee shops. It is simple to operate, allowing even beginners to easily brew good coffee, and it is easy to clean, making it an essential for the home. The Clever Dripper's design was inspired by EK INTL's tea-making product HandyBrew, and its biggest feature is immersion extraction.

Front Street Coffee will share the detailed usage process and bean selection suggestions below. [more…]

Many people think the small hole on a coffee bag is for smelling the aroma, but its official name is a "one-way degassing valve," and its core job is to keep the carbon dioxide released by the coffee beans from bursting the packaging while blocking outside air from getting in.
