Pour-over coffee may seem complicated, but there is actually a low-effort yet stable extraction method—the single-pour center pour. It doesn't require segmented circling; simply keep pouring continuously after the bloom, making it especially suitable for those new to pour-over. This article uses the Yirgacheffe Red Honey Red Cherry recommended by Front Street Coffee as an example, first introducing the classification of honey processing and the proportion of pectin retained, then using the Hario V60 dripper to conduct a comparative brewing of two different grind sizes: a coarse grind BG-7K paired with a longer pouring time, and a fine grind BG-6M paired with a shorter pouring time, to experience the flavor differences under the same coffee-to-water ratio and water temperature. The article also explains in detail how the V60's rib structure affects flow rate, and why pouring stability is far more important than fancy techniques. [more…]

The washed method is currently the most widely used green bean processing method and one of the most traditional coffee processing methods. Typically, washed coffee has higher cleanliness than natural coffee, with brighter and more elevated acidity, and a more intense acidity as well. Popular options on the Front Street Coffee menu, such as the Ethiopian Gotiti Cooperative coffee beans, Kenyan [more…]

Yirgacheffe, as a representative growing region of Ethiopian specialty coffee, presents completely distinct flavors from its natural and washed processing methods. The natural method retains the sugar of the fruit pulp, ferments fully, and brings rich tropical fruit and winey aromas; the washed method highlights the bright acidity of citrus and lemon along with white floral notes. Front Street Coffee takes the washed lot from the Gutingding Cooperative and the natural lot of Red Cherry as examples, comparing processing techniques, cupping performance, and V60 pour-over parameters one by one, helping coffee enthusiasts understand the specific effects of the two processing methods on flavor direction, and offering reusable brewing suggestions.

When brewing pour-over coffee, the drip rate of the coffee liquid often reflects the quality of the extraction. If the flow is too fast, it may lead to under-extraction and a weak, bland flavor; if the flow is too slow, it tends to over-extract, producing bitterness and off-flavors. So what exactly are the factors that influence the flow rate of coffee? Front Street Coffee will break down the key elements affecting flow rate one by one from seven aspects: the pairing of dripper and filter paper, the density and processing method of the coffee beans, the roast level, the grind size, the pouring technique, and the water level inside the dripper. Understanding the relationships among these variables will help you quickly identify the root cause the next time you encounter an abnormal flow rate and make targeted adjustments, bringing every cup of coffee closer to the ideal flavor.

Sumatra Mandheling coffee from Indonesia is famous for its full-bodied mouthfeel and unique herbal and spicy notes. Beyond variety and climate factors, the wet hulling process also plays a key role in shaping these flavor characteristics. Because Indonesia has a tropical rainforest climate with high temperatures and abundant rain year-round, weak winds, and extremely high humidity, conventional washed or natural processing methods struggle to adapt to local conditions, so locals combined the two approaches to create this unique processing workflow. This article will break down each step of the wet hulling method in detail, analyze how it affects the acidity and flavor direction of coffee beans, and also point out that even when the same wet hulling process is used, beans of different quality still show noticeable differences in cleanliness and taste; beans grown at low altitude or improperly handled during drying are prone to earthy and moldy flavors.
