Introduction:The charm of pour over coffee lies in its ability to extract nuanced flavors from coffee using simple tools through precise control. This article details the key points of using two classic brewing devices—the conical dripper and CHEMEX—covering essential parameters such as grind size, water temperature, and pouring techniques, along with clear step-by-step guidance to help you go from a beginner to consistently brewing balanced and rich coffee.
Pour over coffee is not just about pouring hot water over coffee grounds—it is an extraction art that pays attention to details. From bean selection and grind coarseness to water temperature control, stable water flow, and even the path and rhythm of pouring, all directly affect the final flavor presentation. This article will take you deep into the fundamental logic of pour over, and using two common dripper types as examples, it will step-by-step explain how you can brew a well-balanced, layered cup of coffee at home.
Many beginners often ask why the same beans can taste so different when brewed by different people? The key lies in those seemingly small but actually crucial variables: water temperature should be controlled between 90–94°C—too low leads to under-extraction, too high easily brings out excessive bitterness; grind size is generally recommended to be between medium-fine and medium-coarse, which can be fine-tuned according to the characteristics of the device. In addition, the pouring technique and path are equally important. Evenly saturating every coffee particle is essential to bringing out a complete and balanced flavor profile.
For beginners, there are three basic principles worth remembering: First, pour water focused on the central area of the coffee grounds, avoiding continuous pouring at a single point which can lead to over-extraction; second, the water flow should be thin and steady, allowing sufficient contact time between water and coffee; third, you can try imitating Japanese pour over techniques, gently circling in a “の” shape to enhance extraction uniformity. Once you master these points, you’ve taken a key first step in pour over brewing.
Next, we’ll use two classic drippers as examples to explain the operation process in detail. The first is the conical dripper (such as HARIO V60), one of the most common pour over tools, suitable for users who pursue flexible adjustment and flavor layering. Prepare 12 grams of coffee grounds (about one serving), place the filter paper flat in the dripper and gently shake to even it out. Use a gooseneck kettle filled with freshly boiled water, and start pouring when the temperature drops to around 92°C. First, wet the coffee grounds with a small amount of water— if using fresh beans, you’ll observe blooming and bubbling. Let it bloom for 20 to 30 seconds to fully degas. Then, with a stable and fine water stream, pour within a diameter of about 3 cm in the center of the coffee bed, maintaining pace with the dripping speed and avoiding direct impact of the water column on the bottom filter paper. Before the coffee bed fully collapses, continue pouring in a circular motion to ensure all grounds are evenly extracted. Remove the filter paper once the dripping speed stabilizes to avoid affecting the taste with sediment in the final drops.
Another classic option is the CHEMEX, whose unique wide-mouth design and highly permeable filter paper can brew coffee with a relatively clean and clear flavor. Prepare the same 12 grams of coffee grounds, fold the filter paper and place it in the dripper. First, wet the filter paper with hot water to make it adhere to the walls and remove paper taste, then discard the pre-wetting water. Add the coffee grounds and gently shake to even them out. Once the water in the gooseneck kettle cools to about 90°C, begin the first pour by evenly wetting all the coffee grounds with a fine stream, and let it bloom for 20 to 30 seconds. Next, gradually pour hot water up to the middle section of the dripper, observing the coffee’s blooming reaction; once the bubbles gradually dissipate, continue pouring until near the rim, then wait for the liquid level to drop slightly before the third pour. Finally, add water to near the edge for the last time. Maintain a steady water flow throughout. When the coffee is dripping uniformly, you can remove the filter paper to complete the extraction.
No matter which device you choose, the key to pour over lies in stability and patience. From water temperature and grind size to pouring technique, each step requires hands-on practice and fine-tuning to find the combination that best suits your taste. Through continuous practice, you’ll become more attuned to the characteristics of each coffee bean and brew your ideal cup of coffee.
