“There is nothing you can do, you are a supertaster and coffee will always taste bitter.”
I dunno. I really doubt that I am a supertaster. I love every single vegetable. I love dark chocolate (the darker, the better) and I love all other sorts of bitter things. Coffee ice cream is one of my favorite flavors.
Okay, I would recommend a Chemex coffee maker, unbleached filters, high grade beans you grind yourself before brewing, then heavy cream and natural sugar to taste. Use bottled water if your tap water has an off-taste. Old coffee makers and cheap coffee can’t make a decent cup.
