ITEM DESCRIPTION
To ensure the optimal water flow rate for each specific roasting level, the manufacturer employs a varied paper structure for each filter paper. This deliberate design choice enables the water speed to be automatically adjusted during the brewing process, resulting in a precisely controlled flow.
The filter paper under discussion utilizes a "Two-Side Crepe" pattern, with a carefully reduced height of the crepe. Compared to the conventional "One-Side Crepe," this particular design offers a slightly larger surface area. Consequently, the adhesion area for fine coffee powder is also expanded, allowing for enhanced interaction between the water and coffee particles.
During the initial stages of the brewing process, when the adhesion of fine coffee powder is relatively low, water flows smoothly through the filter paper. This unimpeded flow enables efficient extraction and dissolution of coffee solubles, promoting the development of desirable flavours and aromas. However, as the brewing progresses into the latter half, the adhesion of coffee particles gradually increases.
The heightened adhesion in the latter stages of brewing serves as a natural mechanism to regulate the water flow. As the fine coffee powder adheres more strongly to the filter paper, it introduces resistance to the water flow, applying a controlled braking effect. This shift from a fast flow to a slower flow rate facilitates a longer contact time between water and coffee grounds, allowing for a more comprehensive extraction of flavours and contributing to the overall complexity of the brewed coffee.
By employing this intentional variation in water speed, the coffee brewing process achieves a harmonious balance of flavours, resulting in a cup that exhibits a satisfying body and pronounced sweetness. The initial fast water flow aids in extracting the coffee's inherent body, while the subsequent slower flow allows for the extraction of nuanced flavours and aromatic compounds, contributing to the overall sensory experience of the brewed coffee.
This intricate interplay between water flow and the filter paper's unique structure ensures that each cup of coffee is brewed to perfection, capturing the desired characteristics of the specific roasting level. With careful attention to detail and an understanding of the brewing process, this filter paper enables coffee enthusiasts to enjoy a well-rounded and flavourful cup of coffee, showcasing the full potential of the beans used.
