Product Description Brewing Tips Degree of grinding: medium (a little thicker than granulated sugar) Normal water temperature (between 85-92 ℃) Coffee powder is not the finer the better, nor is the coarser the better. If the coffee powder is too thick, hot water flowing too quickly, it is difficult to extract the aroma of coffee. If the coffee powder is too fine, the filter paper is easy to be blocked by the fine powder. Due to the long soaking time of the water in the powder, the water cannot flow evenly in the powder layer, resulting in uneven extraction or over-extraction, coffee will be a bitter taste. Therefore, medium ground coffee is good for hand drip coffee. Tips: When the flow is kept to a minimum, water can be injected from the middle of the layer, appearing uniform bubbles instead of flowing around from the powder surface, thus ensuring a uniform extraction. What is a medium grind? The general metaphor is granulated sugar. To be more specific, pinch it with your finger, the coffee is polygonal, grain by grain, rather than flour.
