Hi there, I’m the new guy in here, that is in deeply love with coffee world, so my Question is about if you guys have experienced in filters Hario v60 the brown one, because even when a rinse with hot water my brewing are tasting as a piece of cardboard.
Brown filters are always going to give you that flavor, regardless of the brand. I would definitely encourage you to get white paper filters, ideally the original Hario v60 brand ones (the ones without the tab on top of them). If you cannot find them, another good option is to fold the melitta #4 white filters so that they fit in the V60.
