We conducted blind-tasting tests on espresso and French press coffee lovers.

They tasted paper-filtered AeroPress brew and metal-filtered brew made with espresso filters and custom filters which were about three times finer. Every single taster preferred the paper-filtered brew.

This is not surprising, in light of the fact that the fine particles which pass through metal filters are quite bitter. In the book Coffee - A Guide to Buying Brewing and Enjoying, renowned coffee author Kenneth Davids wrote about making drip coffee with metal filters; you may not like coffee made with these filters as much as you like coffee brewed with paper filters.

The mesh allows a good deal of sediment and colloids to enter the brewed coffee, which gives it a heavy, often gritty taste, closer in style to French-press coffee.
