Cold brew coffee usually requires 8 to 12 hours of low-temperature slow extraction, but what if you want to drink it the same day? Raising the water temperature can speed up extraction, but if you use hot water directly, it becomes hot brew, and the floral and fruity aromas and low bitterness unique to cold brew will also disappear. Front Street compared three methods through experiments: conventional 23°C cold water extraction for 10 hours, 40°C warm water extraction for 4 hours, and 92°C hot water blooming followed by room-temperature water extraction for 4 hours. The beans used were Colombia · Hanami, with full berry acidity, floral notes, and pink pepper flavors. The results showed that the 40°C warm water rapid cold brew was closest to the performance of conventional cold brew, with both a fermented feel and clearly presented flavors, making it suitable for friends who want to drink cold brew quickly.

Recently, many consumers have noticed that cold drinks at %Arabica stores are now served in kraft paper cups instead of the plastic takeaway cups used previously. According to reports, this change has been gradually implemented since last year, with stores switching to paper cups uniformly after depleting their plastic cup inventory. What was originally thought to be a temporary measure taken only in response to Hong Kong's plastic ban now appears to have expanded to more regions. However, the use of paper cups for cold drinks has raised widespread concerns among customers, including condensation on the cup walls, the cup becoming soft, the papery taste affecting the flavor, and the impact on the visual appeal for photos. At the same time, store staff are also facing challenges with efficiency in serving drinks. How to balance environmental principles with the consumer experience has become the core controversy of this packaging overhaul. [more…]

Cold brew coffee is extracted in a low-temperature, still environment, and many people habitually assume that grinding the coffee finer will increase its strength—but is that actually true? Through comparative experiments, Front Street Coffee found that a coarser grind actually yields a higher TDS reading in cold brew.

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…]

In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [more…]

Under the framework of cold brew coffee's low-temperature slow steeping, there are inherently few adjustable variables—just water volume, water temperature, grind size, and steeping method.

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.

Dirty and iced latte are both combinations of cold milk and espresso, and because they look similar and use the same ingredients, they are often lumped together. But the two have significant differences in cup size, whether ice is added, cup temperature, the purpose of layering, and the way they are drunk. Dirty emphasizes taking a big gulp and experiencing the interwoven layers of hot and cold, bitter and sweet, while iced latte needs to be stirred evenly before enjoying its balanced taste.
