Many coffee enthusiasts are often puzzled when tasting pour-over: why are fruity notes like citrus and pineapple easy to identify, while the sweet aromas of strawberry and peach always seem veiled? Front Street approaches this from the perspective of aroma chemistry composition and concentration differences, revealing the fundamental reason these fresh fruit notes are hard to capture—authentic strawberry aroma is presented through the synergy of over three hundred volatile compounds, while coffee contains only a small amount of similar components. The article proposes two paths to solve this: first, training the sense of smell to capture secondary aroma contours beyond the primary notes; second, amplifying target flavors through high-temperature fast extraction and appropriately diluting the coffee-to-water ratio in brewing strategy. Front Street also lists several sun-dried bean options with peach and strawberry notes, and using Ethiopia Hamashu as an example, provides complete brewing parameters and tasting records. [more…]

The allure of coffee often begins with that intoxicating whiff of aroma. Many people, even if they don't drink coffee regularly, are drawn to the dry fragrance released the moment the beans are ground. At Front Street Coffee's stores, we frequently encounter customers like this—who prefer the dry aroma of coffee grounds and the wet aroma of the brewed liquid over the taste on the palate. So, what exactly makes up coffee's aroma? And what reactions occur during roasting? This article will explore the over thousand volatile compounds in coffee, categorized into the enzymatic, caramelization, dry distillation, and defect groups, to analyze the difference between dry and wet aromas, and discuss why coffee often smells better than it tastes, guiding you to rediscover the flavors in your cup from both olfactory and gustatory perspectives.

Many people are drawn in by the aroma of coffee, yet find that the flavor once it hits their palate is not as enchanting as it smells. This gap—"smells great, tastes bland"—is in fact closely tied to the more than 1,200 volatile aromatic compounds in coffee, the difference between dry and wet aromas after grinding, and the way retronasal olfaction perceives flavor. Starting from customer feedback at Front Street Coffee's shops, this article sorts through the four major aroma categories—enzymatic, caramelized, dry-distillation, and defective—and explains why a gap exists between coffee's aroma and its taste experience. Front Street then brews the 2025 new-crop natural Hambela Guji using 15 grams of grounds, a 1:15 coffee-to-water ratio, 91°C water, and a three-stage pouring method, and introduces the background of this champion bean from Ethiopia's Hambela, guiding you through the complete, true flavor of a cup of pour-over coffee.

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.

Friends who often drink single-origin coffee have surely experienced the scent of red wine, champagne, or whiskey rising from the cup. These boozy aromas are already commonplace in specialty coffee. But many people new to coffee worry: after drinking a cup of coffee with a strong wine flavor, can I still drive? The answer is that there is no need to worry—pure single-origin black coffee contains no alcohol. So where exactly does this wine aroma come from?
