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.

When brewing a good cup of tea, water quality is often more critical than technique. As early as Lu Yu's "Classic of Tea," spring water was regarded as the finest choice, and modern science has revealed the reasoning behind this through TDS, hardness, and pH values. This article focuses on the brewing water for oolong teas such as Phoenix Dancong, outlines the industry reference values from the American Tea Association, and cites multiple studies to explain why soft water enhances the sweetness, freshness, and clarity of the tea liquor, while hard water brings about astringency and floating residue. For tea lovers who cherish the complex aroma of oolong tea, choosing the right water is the first step in unlocking the tea's charm. Front Street Coffee also recommends starting with low-mineralization soft water to appreciate the subtle variations in the tea's layers. [more…]

Coffee extraction methods are not limited to hot water—cold water can accomplish the same process, and the cold brew coffee born from this presents a completely different flavor profile from hot-brewed coffee. Cold brew coffee is mainly divided into two forms: cold steep and ice drip, the former steeping coffee grounds in cold water, while the latter uses the drip filtration principle to extract drop by drop. Many friends ask: should cold steep coffee use hot water or cold water? The answer is actually very clear—coffee brewed with hot water can no longer be called cold steep coffee. Cold steep coffee can only be steeped in room-temperature or ice water, and the entire steeping process needs to be maintained in a low-temperature environment. This article, drawing on Front Street Coffee's hands-on experience, will provide a detailed breakdown of the key details for making a delicious cup of cold brew coffee, covering coffee bean selection, grind size, steeping time, and coffee-to-water ratio.

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…]

The iced pour-over coffee I've shared with you before is the Japanese-style iced pour-over method, which is essentially hot coffee cooled with ice. In this article, Front Street Coffee will introduce a true iced pour-over coffee brewed with ice water—don't blink! Can ice water really brew coffee? A normal cup of pour-over coffee takes only 2-3 minutes to brew, using just [more…]

Regarding what water to use for brewing coffee, there has long been a popular saying: "Don't use purified water." Does this claim actually hold up? Water quality really does influence how coffee flavors express themselves, and purified water is called into question mainly for two reasons: first, its extraction efficiency is on the low side, because the water lacks calcium and magnesium ions to help dissolve flavor compounds; second, purified water has poor conductivity, which can cause the boiler probe in a coffee machine to malfunction, leading to abnormal refilling or even breakdowns. Through comparative experiments, Front Street found that coffee brewed with purified water versus mineral water shows only slight differences in concentration and extraction yield—hard for an ordinary person to notice. What is truly unsuitable for brewing coffee is hard water with a TDS above 175 ppm. This article will analyze these points one by one and offer water-quality recommendations for everyday brewing. [more…]

To brew a delicious cup of coffee, you need not only good beans but also good water. In brewed coffee, water accounts for over 98% of the final cup. Therefore, choosing the right water for brewing is also crucial. So what kind of water is actually suitable for brewing coffee? First, Front Street Coffee will explain the requirements for water suitable for brewing coffee. One [more…]

Drip bag coffee, with its convenient advantages of requiring no grinding and no professional equipment, has become the go-to staple for many people during business trips, office work, and travel. However, quite a few friends report that the drip bag coffee they brew themselves turns out either bland and tasteless or sharply sour and bitter—the problem often lies in three key parameters: water temperature, amount of water poured, and brewing time. This article begins with an introduction to the flavors of Front Street Coffee's classic five-origin drip bag coffee, then systematically explains the suitable water temperature ranges for light-roast and dark-roast drip bags respectively, the selection of coffee-to-water ratios and visual measurement techniques, and how to control the extraction time to around two minutes through staged pouring, helping you brew a delicious cup of drip bag coffee that rivals pour-over in the simplest way possible. [more…]

When brewing pour-over coffee, what temperature should the water actually be set to? Mainstream recommendations fall between 86°C and 93°C—light roasts suit higher temperatures, while dark roasts are better with lower water temperatures. However, the initial water temperature in the pour-over kettle does not equal the actual extraction temperature when it contacts the coffee grounds. Through actual testing, Front Street found that when the water temperature in the kettle is 90°C, the temperature participating in extraction within the coffee bed only remains around 84.5-86°C, with a clear gap between the two. This temperature difference mainly comes from the coffee grounds absorbing heat, the dripper absorbing warmth, and the water flow losing heat as it is exposed to air. As long as you deliberately raise the height of the water stream during the pouring stage, you can accelerate the temperature drop, bringing the effect of a 93°C initial water temperature close to 90°C during extraction. Understanding the relationship between the set parameter temperature and the actual extraction temperature helps you adjust flexibly in daily brewing and consistently present your ideal flavor.

In the past, the iced pour-over recipes we shared mostly involved pouring hot coffee directly over ice to cool it down—a Japanese-style approach. This time, Front Street Coffee wants to try something different—extracting coffee with ice water the whole way through. Ice water is low in temperature and poor at extraction, so it may not seem very reliable, but once you understand the balance between grind size, water temperature, and pouring method, you can actually find a reasonable brewing path. This article will first explain the idea behind brewing coffee with ice water, then use the Costa Rica Strawberry Candy bean as an example to give the dripper choice, grinding parameters, and complete brewing steps, and finally add an extra experiment using soda water instead of ice water to see how the taste changes. [more…]

Besides being extracted with hot water, coffee can also be made with cold water. Coffee made with cold water is called "cold brew coffee," and it has a distinct charm compared to hot-brewed coffee.
