However, after the full name "Pain Mask · Tamarind Americano" was revealed, it triggered consumer worries about the taste. Whether this collaboration drink is a pleasant surprise or a flop will only be known after it hits the market. [more…]

The modern coffee industry has developed various artificial decaffeination processes, including solvent extraction, supercritical carbon dioxide, and the Swiss Water Process. But in an era of technological scarcity, Indonesians had already found an unexpected way to reduce the caffeine in coffee—by plunging red-hot tamarind wood charcoal into brewed coffee. This is Kopi Joss. This street drink was not originally intended for decaffeination, but was believed to relieve stomach discomfort and ward off cold. Research by Ahmad Fauzan, a chemistry student at Yogyakarta State University, found that tamarind wood charcoal has an iodine absorption rate of 83%, which can reduce the caffeine in black coffee from 68.78 mg/100 ml to 55.13 mg/100 ml, with optimal adsorption occurring at 40 minutes. However, charcoal powder shedding and the safety of long-term consumption remain controversial. Front Street Coffee takes you through the science and tradition behind this cup of "hardcore coffee."

In the heat of summer, a refreshing glass of cold brew is the go-to choice for many coffee lovers looking to beat the heat. But have you ever considered that coffee beans blended from two or more varieties can also produce an outstanding cold brew?

This article draws on the hands-on experience of Front Street Coffee, first outlining the characteristics of cold brew and the advantages of blended beans, then recreating several blending experiments one by one: from Sidra with Geisha, Pacamara with Red Cherry, to Huakui paired with Strawberry Candy and Wangshan Geisha, and finally challenging the dark-roasted Queen's Estate blended with Flower God. Some of these recipes are full-bodied and layered, while others flop into a "mask of pain," yet they perfectly showcase the fun and possibilities of blended cold brew. [more…]

Facing Long Black, Lungo, and Americano on the menu, many coffee lovers often can't tell them apart. Although they are all black coffee, their preparation methods and flavor profiles each have their own merits.

During Halloween, major tea beverage brands have rolled out holiday-exclusive drinks to compete for young consumers. Nayuki has partnered with "Harry Potter" for a second time, launching a "Sugar-Free Blood Orange and Grapefruit" drink themed around Voldemort's "Dark Magic." However, this beverage, which uses blood orange and grapefruit to create a "blood-colored" atmosphere, has drawn complaints from consumers because the grapefruit peel was not removed, and the bitterness intensifies after prolonged steeping. Fans reported that the drink gets more bitter the more they sip, with some describing it as "more bitter than Americano." Nayuki staff explained that the grapefruit peel is kept to show the use of real ingredients, and advised drinking it as soon as possible or picking out the peel oneself. Nevertheless, some fans of the books took the bitterness in stride, saying it fits the Dark Magic theme. [more…]

Entering May, coffee brands have密集 launched a wave of new sparkling water and coffee combinations, from KFC's herbal tea sparkling Americano to Luckin's orange-gold sparkling Americano, with discussion heat on social platforms continuing to climb.

This article sorts out recent developments in various brands' sparkling new products, the causes of splashing and operational techniques, as well as the ice-amount game between brands and consumers. Front Street Coffee reminds that when tasting such drinks, one should also pay attention to the carbonation characteristics to avoid affecting the experience. [more…]

Recently, a trend of pouring Huoxiang Zhengqi Shui (a traditional Chinese medicine for heatstroke) into iced Americano has spread rapidly online, with many coffee enthusiasts eager to try it. From the earlier practice of adding ice cubes to herbal tea, to later mixing traditional Chinese medicine granules into coffee, and now directly pouring Huoxiang Zhengqi Shui into iced Americano, these "medicated coffee" concoctions keep escalating. However, Huoxiang Zhengqi Shui is, after all, a medicine, and its ingredients may irritate the stomach and intestines. When mixed with coffee, it can easily trigger gastrointestinal spasms, leading to abdominal pain, diarrhea, vomiting, and other discomforts. Curiosity is understandable, but casually mixing medicine with coffee has crossed the boundary of safety. This article will start with the origins of this trend and discuss why this way of drinking is not worth promoting. [more…]

In coffee cupping, "balance" is an important scoring dimension, but what it measures goes far beyond the simple harmony of acidity, sweetness, and bitterness. The interrelationship among four elements—acidity, sweetness, body, and aftertaste—is the true criterion for judging balance. Blue Mountain coffee has always been renowned for its balance; even though it may not excel in any single aspect on its own, it delivers the most comfortable overall experience. Starting from Front Street Coffee's cupping experience and drawing on specific cases, this article analyzes the meaning of balance, and explores the reasons behind Blue Mountain coffee's high price as well as the unique advantages of its Typica variety.

In the coffee world, adding water directly to brewed coffee has a special name—By pass. This operation bypasses the coffee grounds, does not participate in extraction, and is only used to adjust the concentration in the final cup. Many people are curious: can adding water really make coffee taste better? The answer depends on the situation—if the coffee itself is bitter and astringent, no amount of water will save it; but if the cup is properly extracted and just too concentrated, suppressing its flavors, then adding an appropriate amount of water can actually restore the deliciousness it should have. From Front Street's perspective, this article combines examples such as making Americano from espresso and adjusting concentration in pour-over to explain the sensory principles behind it and practical methods for judgment.

From the perspective of Front Street, this article breaks tasting down into three dimensions—"color, aroma, and flavor"—teaching you to observe the crema, sniff the aroma, and savor the finish, while also providing a specific drinking routine and a reminder about the golden tasting window, helping you truly appreciate the charm of espresso.
