In the past two years, a coffee processing method called "rapid chilling to lock in aroma" has become popular in competitions and among enthusiasts, shared and promoted by Sasa Sestic, with the core tool being the Paragon chiller ball. It works by rapidly lowering the temperature of the coffee liquid to slow down aroma volatilization, theoretically preserving more flavor. But how effective is it really? Why do most competitors only rapid-chill the first portion of the coffee liquid? Front Street conducted a comparative test using a pour-over of Huakui and a Strawberry Candy espresso, and found that the aroma difference in the pour-over group was not obvious, while the espresso group showed mouthfeel differences due to temperature changes. This article will break down in detail the principle of rapid chilling to lock in aroma, the results of the comparative experiment, and the two major reasons for only chilling the first half, helping coffee enthusiasts view this technique rationally.

Dirty coffee has become a staple in specialty cafes thanks to its high aesthetic appeal and unique taste, yet there has always been debate over whether an ice-cold cup is essential during preparation. Through side-by-side testing of glass cups at room temperature, refrigerated, and frozen, Front Street found that milk quality is the key to layering, while cup temperature mainly affects the chilled mouthfeel and the preservation of crema. The article also traces the practice of Dirty's originator, Katsuyuki Tanaka, who did not pre-chill his cup. If you're after photogenic presentation and a layered experience, Front Street recommends chilling the cup together with the milk and paying attention to the optimal tasting window. [more…]

In recent years, more and more coffee enthusiasts have begun trying their hand at making cold brew and ice drip coffee at home, and the ice drip coffee produced by Front Street Coffee is often in short supply. Many friends are concerned about: how long can this kind of low-temperature extracted iced coffee be kept after being placed in the refrigerator? Why does ice drip coffee actually taste better after 12 hours of refrigeration? This article will focus on the principles of low-temperature extraction, equipment selection, coffee bean recommendations, and the flavor evolution during refrigeration, systematically answering the shelf life and optimal drinking time of iced coffee, helping you both enjoy great taste and ensure safety.

Coffee aroma is volatile, and the higher the temperature, the faster it dissipates, so some have proposed using low-temperature containers to lock in the aroma. Front Street Coffee compared three types of pour-over coffee vessels—a high-temperature cup, a room-temperature cup, and a frozen cup—to test whether cup temperature truly affects coffee aroma and flavor performance. The experiment used Kenya Asaliya coffee beans with uniform brewing parameters, and the results showed that cup temperature mainly changes the temperature of the coffee when it enters the mouth, rather than the amount of aroma, but temperature differences do indeed cause noticeable changes in flavor perception. This article will present the experimental process and conclusions in detail, and offer cup selection suggestions for different weather conditions. [more…]

Although they are all iced coffee, cold drip, cold brew, cold extraction, and iced chilling are often lumped together. They appear to all rely on low temperatures, but in reality their extraction paths, time requirements, and flavor directions are each different: cold drip emphasizes slow dripping and a fermented character, cold brew uses long soaking in exchange for a clean and smooth result, while iced chilling is a quick solution involving hot extraction followed by rapid cooling. This article breaks down the differences among the four from the perspectives of brewing principles, water flow control, water-to-coffee ratio, grinding, and bean selection, while retaining specific recommendations such as Front Street Coffee Mandheling and Yirgacheffe, to help coffee lovers make more suitable choices in different scenarios.

Americano may look like nothing more than espresso with water, but how much water you add and what ratio you use directly determine whether a cup tastes good. This article focuses on the water-to-espresso ratio for Americano, explaining what water-to-coffee ratios suit coffee beans of different roasting styles and flavor profiles, and using a classic Italian blend as an example to give a reference range of 1:7 to 1:8. The article also breaks down in detail the specific parameters Front Street Coffee uses to make iced Americano: 40g espresso, 100g large ice cubes, and 120g water, i.e. 1:2.5:3, and further introduces the preparation order for the hidden menu item "all-ice Americano" — put the ice in first, then pour in the espresso, using the principle of extract cooling to lock in aroma and speed up chilling, for a better mouthfeel and flavor performance.

In coffee shops, ordering an iced americano without ice is not uncommon, but have you ever heard of asking for an iced americano "without water"? This drink, known as an espresso over ice or iced espresso, is actually just espresso coming directly into contact with ice cubes. It has a rich mouthfeel and bright acidity, with less bitterness compared to hot espresso. This article will explain in detail the origins of this drinking method, how to make it, and, drawing on the "extract chilling" concept of 2021 WBC barista Hugh Kelly, explain why rapid cooling can lock in more aroma. At the same time, Front Street Coffee recommends a series of espresso beans suitable for making iced espresso, helping you easily recreate a professional flavor. [more…]

American coffee may seem simple, but many details determine the final taste. Based on Front Street's practical experience, this article first explains that a delicious Americano requires a suitable espresso base and proper concentration, then shares three "tricks" to enhance the texture: First, pay attention to the hardness of the dilution water, because water accounts for over 97% of black coffee, and soft water can bring out a more noticeable sweetness; Second, choose whether to keep or remove the crema on the surface of the espresso according to personal preference—removing it improves cleanliness and sweetness, while keeping it provides better body and aftertaste; Third, use ice cubes to directly catch the espresso and then shake to dilute, drawing on the concept of rapid freezing to preserve aroma and lower the temperature. In addition, the article also compares the differences between Italian coffee and American coffee, and recommends several Front Street espresso beans suitable for making non-bitter Americanos, including Strawberry Candy Blend, Commercial Blend, Huakui SOE, and Yirgacheffe Natural Red Cherry SOE.

Kenyan coffee is famous for its bright acidity and berry flavors, which are inseparable from its unique varietal genetics and processing methods. The Bourbon lineage cultivated in the early twentieth century, plus the two disease-resistant, high-yield varieties SL-28 and SL-34, nurtured a distinctive acidic aroma in Kenya's high-concentration phosphoric acid soil. Kenya's signature double washing method (K72), through two fermentations and repeated washing, further amplifies the bean's cleanliness and acetic acid concentration. Because of its bright acidity and elevated flavors, Kenyan beans are especially suitable for making iced coffee. This article will systematically sort out the varietal origins and washing process of Kenyan coffee, and share Front Street Coffee's specific parameters and operational details for three methods: iced pour-over, iced drip, and cold brew.
