i was going to start a new thread but i figured i would try in here first. i've been using unbleached filters with my own roasted coffee for quite some time. i was making good tasting coffee following what everyone here has recommended. last week i bought a box of bleached filters since i've seen many people say the unbleached taste "papery". i wanted to see if theres a difference myself. for some reason, the last three batches have pretty much stalled halfway through. i'm using the same method and grind. the only difference is the filter. i usually ground at a 4.5 on my mazzer and on the most recent one i did it at 6. i may have gotten a little more out of it, but not even halfway there. all three times i used the same coffee--could that be the issue? i dont have any other coffee to try right now-got behind on roasting. has anyone else switched between unbleached and bleached and had issues like this?

Ben's (the funk's) coffee is MASSIVELY over-extracted. His brew ratio is almost 30:1 !!!! No wonder it's bitter. Considering how weak it is already, I can't imagine diluting it would improve the overall result.
Coarser grind, more coffee, less water. Go for 60g coffee / liter (35oz) of water. If you're going to err, make it a quart of water.
As has already been posted by people smarter than me, go for 4min total pour time.
You're asking a completely different question. It deserves its own thread.
