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.

Cold brew coffee, put simply, is coffee extracted with cold water.

Cold brew coffee typically requires a steeping time of more than 8 hours, followed by a period of maturation to reveal its full flavor. But many coffee enthusiasts want to shorten the waiting time, so some bloggers have shared a method for "making high-sweetness cold brew in one minute"—using a hand press or espresso machine to extract with cold water at 9 bar of pressure. Front Street Coffee has also experimented with ice-water extraction, and the result was a cup of cold brew that looked decent in just a few minutes, but tasted like little more than coffee-flavored water, with a mouthfeel and strength far inferior to the long-steeped version. This article analyzes in detail the principles and limitations of rapid cold brew, explains why flavor compounds cannot be fully dissolved at low temperatures even under pressure, and offers a more feasible way to shorten the time: appropriately raising the initial steeping water temperature. It also answers common questions such as how long cold brew coffee can be stored. [more…]

Neither ice drip coffee nor cold brew coffee relies on high-temperature hot water; instead, they complete extraction entirely with low-temperature water, and therefore take far longer than iced Americano or iced pour-over.

Starting from Front Street Coffee's practice, this article first explains the basic principles of low-temperature extraction, then explains the suitable grind size, and next separately breaks down the specific parameters of time and coffee-to-water ratio for ice drip's drip-style extraction and cold brew's immersion-style extraction, and finally uses the same Front Street Ethiopia Yirgacheffe Natural Red Cherry coffee beans for comparison, presenting the differences in mouthfeel and flavor brought by the two methods, to help you find a brewing solution that suits you.

Coffee made with cold water is called "cold brew coffee," and it has a distinct character compared to hot-brewed coffee.

[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.

From the perspective of Front Street Coffee, this article sorts out the origins of cold brew coffee, the key points of water temperature and time, its differences from ice-drip coffee in extraction method and flavor layers, and recommendations for coffee beans suitable for making cold brew. Whether you prefer a rich, consistent cup or a bright, layered one, you can find the right one for you. [more…]

Even though they are all iced coffees, cold brew, ice drip, nitro cold brew, and iced Americano actually differ greatly in their extraction methods and flavor profiles. Cold brew soaks coffee grounds in cold water for a long time, taking about 8 to 12 hours to complete, and has a mellow, sweet taste with lower acidity; ice drip, on the other hand, lets ice water pass through the coffee grounds drop by drop, followed by several hours to dozens of hours of refrigerated fermentation, resulting in a more delicate aroma. Nitro cold brew creates dense bubbles and a beer-like texture by injecting nitrogen. Iced Americano is made by cooling and diluting espresso after high-temperature extraction. This article will review the production processes, advantages and disadvantages, and market trends of these coffees, and include practical tips for making cold brew at home, while also retaining bean recommendations such as Front Street Indonesia Mandheling and Front Street Ethiopia Yirgacheffe.

Cold brew coffee has swept across the United States in recent years, but the prototype of cold-water extraction actually appeared in Kyoto, Japan, as early as the 17th century.
