In the daily practice of pour-over coffee, some people habitually rinse the paper filter with hot water before brewing, while others place a dry filter directly into the dripper and start pouring.

What practical effects does rinsing the paper filter actually bring? And what impact does skipping this step have on extraction? This article will examine three angles—removing papery taste, preheating the equipment, and helping the filter adhere to the dripper—while also analyzing the problems that wetting the filter may cause, such as obstructing the bloom and degassing, prematurely extracting the coffee grounds, and the filter absorbing water, to help you make a more suitable choice in different brewing scenarios.

The processing method of green coffee beans directly determines the flavor direction of the final cup. From the oldest sun-drying to the washing process invented by the Dutch in the 18th century, and then to the semi-dry processing in between, each method has left a unique mark on the coffee beans.

In addition, locally adapted innovative processes such as Indonesia's wet-hulling method have also added distinctive regional characteristics to the coffee world. This article will take Front Street Coffee's cupping experience as an example to break down the principles, steps, and flavor performance of these processing methods one by one. [more…]
