Coffee beans naturally contains oils which float on water. You can see oil on the surface of dark roasted beans. Even light roasted beans contain the same amount of oils, but they haven't been forced to the surface by extended roasting. Paper filters, bleached or not, remove some of the oils and re-filtering removes more oils. The effect on flavor is subtle.
FAQ
- previous post: I have been using your aeropress in conjunction with Kyocera slim manual coffee mill and Porlex mini grinder for around 12 years almost daily. We love the coffee that it produces. What kind of electric coffee grinder do you use when grinding coffee for the aeropress? I am considering switching from manual coffee bean grinding to using an electrical coffee bean grinder. I am making coffee from both espresso coffee beans and Columbian coffee beans. – From Eileen W.
