##
The HARIO KDC-02-B V60 Kasuya Model distinguishes itself from the standard V60 with its unique smooth bottom design, which markedly slows the flow rate during brewing. This design is optimized for the Kasuya 4:6 method, requiring coarser grinds and a slower extraction process to achieve brewing consistency. Unlike the standard V60, which features ridges for faster draw-down, the Kasuya Model's smooth base guarantees thermal stability by retaining heat longer, enhancing flavor extraction. This makes it ideal for extended brew times, typically 7-10 minutes, but unsuitable for traditional V60 techniques. The porcelain construction further contributes to thermal stability, maintaining consistent temperatures throughout the brewing process. However, its slower flow rate demands precise grind size adjustments to avoid over-extraction, securing balanced and flavorful results.
Features and Benefits
The HARIO KDC-02-B V60 Kasuya Model features a smooth bottom design that slows the flow rate, optimizing it for the 4:6 brewing method and enhancing extraction control. Its porcelain construction guarantees superior heat retention, maintaining consistent brewing temperatures for extended periods. These design elements collectively support a more controlled and flavorful pour-over experience, particularly suited for coarser grinds and the Kasuya technique.
Smooth Bottom Design Slows Flow
Featuring a smooth bottom design, the HARIO KDC-02-B V60 Kasuya Model distinguishes itself from the standard V60 by intentionally slowing the flow rate during brewing. Unlike the standard V60, which uses spiral ridges to promote faster water flow, the Kasuya Model's flat base enhances flow regulation, allowing for extended contact time between water and coffee grounds. This design is pivotal for achieving brewing precision, particularly when using coarser grinds, as it prevents over-extraction and bitterness. The slower draw-down time, typically 5-6 minutes for a 24-gram dose, guarantees a balanced extraction, emphasizing clarity and depth in flavor. This feature makes the Kasuya Model ideal for methods requiring controlled flow, though it is less suited for traditional V60 techniques that rely on faster brewing times.
Optimized for 4:6 Method
Designed specifically for the Kasuya 4:6 method, the HARIO KDC-02-B V60 Kasuya Model excels in delivering precise control over extraction, making it a standout choice for enthusiasts of this technique. Its smooth bottom design, combined with a slower flow rate control, guarantees peak brewing accuracy by accommodating coarser grinds and extended draw-down times. Unlike traditional V60 models, this brewer is tailored for the 4:6 method's two-pour process, emphasizing a 2-minute bloom followed by controlled pours to achieve balanced extraction. The slower flow rate prevents over-extraction, enhancing flavor clarity and strength. This design contrasts sharply with standard V60s, which prioritize faster brews, making the Kasuya Model uniquely suited for those seeking a methodical, flavor-focused approach to pour-over coffee.
Porcelain Ensures Superior Heat Retention
Why does the HARIO KDC-02-B V60 Kasuya Model stand out in heat retention? Its porcelain construction offers superior thermal conductivity, ensuring even heat distribution throughout the brewing process. Unlike plastic or stainless steel alternatives, porcelain retains heat more effectively after preheating, maintaining a stable temperature critical for ideal extraction. This material's low thermal conductivity minimizes heat loss, allowing the brewer to sustain the perfect brewing environment for extended periods. The result is a consistent and controlled extraction, enhancing flavor clarity and reducing the risk of under-extraction. Compared to standard V60 models, the Kasuya Model's porcelain design excels in preserving heat, making it ideal for the slower 4:6 method, where precise temperature control is paramount for achieving balanced, flavorful coffee.
Smooth Bottom Enhances Extraction Control
The HARIO KDC-02-B V60 Kasuya Model's smooth bottom design distinguishes it from standard V60 brewers, which typically feature ridged interiors. This unique design slows the flow rate, offering greater flow rate precision and enhancing extraction consistency. Unlike traditional V60 models, the smooth bottom minimizes turbulence, allowing for a more controlled and even extraction process. This is particularly beneficial for the Kasuya 4:6 method, which relies on coarser grinds and extended brew times. The absence of ridges guarantees a steady draw-down, reducing the risk of over-extraction and bitterness. This design choice makes the Kasuya Model ideal for achieving balanced, flavorful brews, though it requires adjustments in grind size and technique compared to standard V60 methods. The result is a brewer optimized for precision and consistency in specialty coffee preparation.

Kasuya 4:6 Brewing
Kasuya 4:6 brewing, a method developed by Tetsu Kasuya, is specifically designed to optimize flavor extraction through precise control of water flow and grind size. The kasuya technique emphasizes brewing precision by dividing the total water into a 4:6 ratio, with 40% used during the bloom phase and 60% in subsequent pours. This approach enhances flow control, ensuring even saturation and extraction balance. The HARIO KDC-02-B V60 Kasuya Model is tailored for this method, featuring a smooth bottom design that slows water flow, ideal for coarser grinds. Unlike traditional V60 brewers, this model supports extended draw-down times, aligning with the 4:6 method's requirements. By focusing on extraction balance, it produces a nuanced, flavorful cup, making it a specialized tool for enthusiasts of the kasuya technique.
Coarse Grind Compatibility
Coarse grind compatibility is a defining feature of the HARIO KDC-02-B V60 Kasuya Model, enabling it to excel in the 4:6 brewing method. Designed specifically for coarser grinds, this brewer guarantees peak grind consistency and particle uniformity, critical for achieving balanced extraction. Unlike standard V60 models, its smooth bottom design slows the flow rate, preventing under-extraction and enhancing flavor clarity. The Kasuya Model's compatibility with coarse grinds aligns with the 4:6 method's emphasis on controlled pour intervals, allowing for precise manipulation of sweetness and acidity. This design contrasts sharply with traditional V60 brewers, which often require finer grinds for faster draw-downs. By prioritizing coarse grind compatibility, the Kasuya Model delivers a robust, nuanced cup, making it ideal for enthusiasts seeking mastery over extended extraction techniques.
Extended Extraction Benefits
Extended extraction benefits are central to the HARIO KDC-02-B V60 Kasuya Model's design, enabling it to produce a more nuanced and complex cup of coffee.
