Last Updated: 2024/11/08, Infiltrating filter droplets are generally extracted with small water flow and slow extraction to prolong the contact time between water flow and coffee powder to achieve full extraction.

Infiltrating filter droplets are generally extracted slowly by small water flow.

Lengthen the contact time between the water flow and coffee powder to achieve full extraction. The wetting type requires digging a hole in the middle of the coffee powder because the scope of the infiltrating water is wider. If the outer powder layer is too thin, the powder may follow the water flow to the center, so that the fine powder floating in the periphery is over-extracted. Generally speaking, the porous filter cup is more suitable for wetting extraction, because the direction of the water passing through the powder is more dispersed.
