Cold brew coffee has always been known for its long, low-temperature steeping, often requiring 5 to 24 hours when made with room-temperature water. To shorten the wait, some people have tried steeping coffee grounds in warm water. This article explores the differences between cold-water and warm-water extraction, the reasons why cold brew has lower acidity, and a warm-water cold brew comparison test using Front Street Coffee's Elida Catuai. It records the sensory differences between 3 hours in 45℃ warm water and 7 hours in room-temperature water, and offers bean selection advice and practical tips for warm-water cold brew. [more…]

On a cold winter morning, a glass of warm water at just the right temperature can quickly warm the body and awaken dormant functions. Now, a café in Japan has put this everyday drink on its menu, selling it under the name "Ultimate Artisan Warm Water," priced at 500 yen (about 25 yuan) for three cups. The shop uses a ceramic kettle to hold groundwater, boils it, lets it sit to cool, and finally serves it to customers at around 65°C. Some find it thoughtful and warming, while others question why they can't just boil water themselves. Meanwhile, bottled warm water that a Japanese convenience store once offered for a limited time has become a regular product after sales exceeded expectations by three times. Whether this warm water trend will spread in the coffee industry is worth watching. [more…]

To enjoy a cup of cold brew coffee with outstanding sweetness at home, you actually don't need expensive equipment. Using 50 grams of coffee grounds as a baseline, Front Street Coffee shares the complete parameters from grind size and coffee-to-water ratio to refrigeration extraction time.

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.

Many tea brewers are in the habit of first warming their cups and rinsing their teapots, believing this cleans the utensils, raises the temperature, and releases aroma.

Hot Americano may seem like just espresso with hot water, but the water temperature directly affects the aroma, the balance of acidity and bitterness, and the drinking window. Front Street Coffee used the Warm Sun blend as the base and brewed Americanos at four water temperatures—55°C, 65°C, 75°C, and 90°C—then compared them through tastings at three points: immediately after brewing, at the 5-minute mark, and at the 20-minute mark. The experiment found that at the moment of serving, 65°C delivered the best overall performance, while over the course of 20 minutes, 75°C performed better overall. The article also recommends a serving temperature of 75±5°C for dine-in hot Americanos and offers practical tips such as preheating the coffee cup and distinguishing between dine-in and takeaway preparation.

In the process of coffee making, whether cups need to be preheated in advance has always been a topic of discussion among enthusiasts. For espresso, warming the cup is almost indispensable, because drinks such as espresso, latte, and cappuccino noticeably deteriorate in flavor after their temperature drops. The situation with pour-over coffee is somewhat different: it allows you to taste layered changes across different temperature ranges, and the serving temperature itself is relatively high, so whether to warm the cup depends more on the actual scenario and needs. This article will combine Front Street Coffee's practical comparisons to analyze in detail the respective effects of cup warming on espresso and pour-over coffee, and provide specific suggestions for different cup types, helping you make a more suitable choice in your daily brewing.

What kind of flavor performance would using warm milk instead of cold water to extract coffee bring? Front Street Coffee conducted a comparative experiment with three beans of different roast levels and found that the medium-roast bean, when soaked in warm milk, had both fruity aromas and chocolate notes, and its mouthfeel was the most appealing. But the experiment also revealed the problem that a milk temperature of 40°C combined with a granulated sugar grind size and a 3-hour soak easily led to over-extraction. For this reason, Front Street adjusted the plan, shortening the time to 1.5 hours and switching to Ethiopian Santa Vini beans, obtaining a smooth milk coffee interwoven with honey, pineapple, and cream biscuit notes. This article fully records the experimental process and tasting results, providing a reference for enthusiasts who want to try milk-extracted coffee. [more…]
