Introduction:On hot summer days, iced pour-over has become the go-to choice for many coffee enthusiasts. However, replicating online recipes at home often leads to issues like flat flavors or under-extraction. This article delves into two highly acclaimed iced pour-over methods — KURASU’s stirring technique from Kyoto and Amis’s ice-shaking method from Taiwan. From equipment selection and brew ratios to detailed steps, we’ll guide you through key techniques to enhance extraction efficiency and flavor complexity, breaking down practical examples to help you easily brew an iced coffee with both bright acidity and rich aftertaste.
As temperatures rise, the demand for iced coffee grows, and iced pour-over stands out among coffee lovers for its flexibility and flavor profile. However, many who try to recreate popular online iced pour-over recipes at home often encounter problems like incomplete extraction or weak flavors. This article focuses on two widely popular iced pour-over techniques — the stirring method originating from KURASU COFFEE in Kyoto and the ice-shaking method created by Taiwanese barista Amis. Both use standard pour-over tools but offer different approaches to improving extraction efficiency and flavor balance. Using an Ethiopian Yirgacheffe sun-dried bean as an example, we’ll detail pouring techniques, brew ratios, timing, and final flavor characteristics to help you find your ideal iced pour-over method.
As spring approaches, iced beverages are making a comeback on café menus. Whether it’s cold drip, cold brew, or customizable iced pour-over, they’re all refreshing and energizing choices. We’ve previously explored and compared various aspects of iced pour-over, from ice addition timing and ratios to ice-ball cooling and stainless steel ice tubes. For beginners, this information is enough to meet basic needs, but many readers still report that even when following the recommended steps, they struggle to achieve satisfying richness and complexity — flavors may turn out too light or one-dimensional. That’s why we’ve carefully selected two highly practical iced pour-over methods from real-world experience, offering more intuitive and beginner-friendly operation guides.
First up is KURASU COFFEE’s stirring method from Kyoto. This technique uses only common pour-over tools, requiring just an additional small stirring spoon, making it ideal for situations where smaller coffee doses are preferred. Its basic parameters are not far off from typical iced pour-over recommendations. The highlight of this method is that stirring boosts overall extraction efficiency, reducing reliance on pouring skills, so even beginners can easily master it. For filter cone selection, if you enjoy bright and vibrant fruity acidity, a V60 or similar conical dripper is recommended. If you prefer a smoother, balanced taste, a flat-bottomed cake dripper can be used to enhance immersion extraction. Additionally, using larger ice cubes helps minimize the impact of melting on extraction temperature.
For beans, light to medium roasts with fruity acidity tend to perform well. Common high-quality origins include Ethiopia, Panama, Colombia, and Costa Rica, where beans are often processed via sun-drying, honey processing, or anaerobic fermentation. The resulting iced coffee boasts pleasant aromas and a refreshing taste. For this demonstration, we’re using a recently well-received Ethiopian Yirgacheffe sun-dried bean. When brewed hot, it often exhibits magnolia flower notes, juice-like body, and a candy-like finish, making it equally suitable for iced pour-over preparation.
This stirring method follows a three-stage pouring design combined with stirring actions: The first step involves pouring 40g of hot water in a small, steady stream in circular motions over the center of the coffee bed, while simultaneously stirring back and forth with the small spoon. Repeat this three times to encourage the coffee grounds to quickly absorb water and release soluble flavor compounds. Once the coffee liquid in the dripper is nearly fully drained (around 40–45 seconds), switch to a slightly larger stream and pour 60g of hot water in circular motions without stirring. Finally, pour the remaining 50g of hot water in a small, tight circle and stir once more with the spoon in large circles along the edge of the dripper. Then let the coffee drip through completely. The total extraction time is approximately 2 minutes and 1 second. After brewing, mix the coffee with ice thoroughly by shaking. According to actual tasting experiences, this method produces an iced coffee with a rounded black tea-like character. Upon tasting, you’ll notice bright acidity notes of passionfruit, citrus, and orange, followed by a hint of caramel sweetness in the aftertaste. The overall profile is clean and layered.
Another technique worth trying comes from renowned Taiwanese barista Amis. His ice-shaking method emphasizes shaking the brewed hot coffee with ice after extraction to fully integrate them, thereby enhancing aroma and flavor complexity. To achieve a sufficiently concentrated base coffee, this method uses a relatively large coffee dose, finer grind size, and higher water temperature, combined with extended blooming time and a higher brew ratio (up to 1:8) to reach the goal of high concentration with low extraction rate.
The specific steps are as follows: First, perform a long bloom with 30g of hot water, using a small stream in circular motions for about 1 minute. This helps evenly preheat the coffee grounds and release initial flavors. After blooming, continue pouring the second stage of 130g of hot water with a small stream, avoiding circular movements and keeping the water column focused on the center of the liquid surface. Slow the flow rate to allow the liquid level to rise gradually. This entire process completes filtration in about 2 minutes and 10 seconds. Finally, pour all the freshly extracted hot coffee into a shaker filled with 120g of ice, tightly seal it, and shake vigorously. Once you feel the coffee has visibly cooled, pour the mixture through a filtered strainer into a cup to serve. This method yields an iced coffee showcasing elegant floral notes and the sweet-tart profile of ripe tropical fruits. You can clearly taste delicate flavors like guava, dried mango, preserved fruit, and blueberry. The mouthfeel is cool, sweet, and refreshing. However, due to the more extreme parameter settings, this technique demands higher control over flow rate and bean quality. Special attention must be paid to grind size and water temperature to avoid over-extraction or off-flavors.
