When brewing pour-over coffee, even if the water quality, technique, and timing are all normal, under-extraction can still occur, and the problem often lies with the water temperature. Beans of different roast levels have different water temperature requirements: light-roasted beans are dense and need higher water temperatures, while dark-roasted beans have a loose structure and are better suited to lower water temperatures. Front Street Coffee typically uses 91~93°C for light-roasted beans and 86~89°C for dark-roasted beans, making fine adjustments based on the condition of the beans and the grind size. In addition, details such as the pouring height and whether the kettle spout and dripper are preheated can also affect the actual water temperature, thereby changing the extraction effect. This article will analyze the logic of water temperature selection in detail and share how to maximize the efficiency of hot water through operations such as preheating, making the coffee flavor more pleasant.

Many coffee enthusiasts set the water temperature at 92°C when brewing, yet often run into under-extraction. The reason is that as hot water is poured from the kettle and travels to the coffee grounds, heat is constantly lost, so the actual temperature is often lower than the set value. This article will break down the major causes of water temperature loss, including the effects of the kettle neck, air, and dripper material, and offer practical countermeasures such as preheating equipment, lowering the pouring height, and adjusting the water temperature to help you brew a good cup consistently in different environments. The article also uses Front Street Granja Geisha as an example to explain how to flexibly adjust parameters according to ambient temperature, making extraction more reliable. [more…]

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.

A cup of pour-over coffee reveals a completely different flavor perception at different temperatures. When hot, bitterness is suppressed and the sour-sweet notes stand out; at the medium-temperature stage, sweetness and the sweet aftertaste are at their fullest; once cooled, bitterness and acidity rise together while sweetness fades. Through comparative experiments, Front Street Coffee found that the reason hot pour-over has a more complete flavor comes down to ample water and full extraction. Iced pour-over, by contrast, requires less water and a finer grind to cool quickly, yet this easily brings out bitter, harsh off-notes from too many fines. Starting from parameter differences, experimental data, and tasting feedback, this article systematically explains why, if you want flavor, you should drink hot pour-over. [more…]

When the weather turns cold, many coffee enthusiasts notice that even with the same beans and the same technique, the coffee they brew comes out weak and lacking in flavor. This is not a problem with the bean roasting, but rather the low-temperature environment changes the rate at which the hot water loses heat, which in turn affects extraction efficiency. Starting from the principle of heat loss, this article explains in detail how cooling leads to under-extraction, and offers four actionable improvements: preheating the kettle spout, raising the water temperature, increasing the water volume, and lowering the pouring height. Finally, it includes Front Street Coffee's store information to help you consistently produce a delicious pour-over even in the cold season. [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.
