Description

The 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. Virtually all white filter papers manufactured today are whitened without use of dioxin, a carcinogen that was used in bleaching paper through the late 1980s. For this reason, I feel confident in recommending white papers in preference to brown, which imparts a cardboardy taste to the brewed water and which may harbor some dubious chemicals of their own, including tars.’
