An Analysis of the Differences Between Flannel Filter Cloth, Metal Filters, and Pour-Over Paper Filters: A Comprehensive Comparison from Filtration Materials to Extraction Flavor

In the world of coffee brewing, the choice of filtration medium often determines the flavor direction in the cup. From Turkish coffee, which was mainly boiled before the 19th century, to the filter paper and dripper invented by Mrs. Melitta, to the artisanal use of flannel cloth in Japan, each filtration method carries a different extraction logic.

Do You Need to Rinse Pour-Over Coffee Filters First? A Full Guide to Buying Tips and Proper Use

When brewing pour-over coffee, should you really pre-wet the paper filter? This is a confusion many people encounter when they first get into pour-over. Some insist that wetting the filter is essential, while others brew directly with a dry filter. Which approach is actually more reasonable?
