Currently I have a standard Melitta Filter and a standard water kettle. I have read and heard that the pouring speed makes a big difference for the result but I can’t really control that very well with the spout of said kettle.
Currently the coffee tastes like a mix of under- and overextracted which is really confusing. I have tried different grind settings before but the issue persists.
Edit: The mix in over- and underextracted might also come from me not stirring before drinking the coffee.
Is there a way to improve this without getting a new kettle? What other things can I try?
Edit: I have now tried pouring with a Pyrex type measuring cup and it pours much better than the water kettle. Combined with stirring afterwards it noticeably improved the taste. The grinder I use is the Timemore C3 ESP pro.
Thanks everyone!


That piece of porcelain sucks up all the heat from your water. Invest in a cheap plastic V60. They cost just a few euros.
Get some decent paper filters for it. I would recommend Cafec ABACA (not the plus version!) but the Hario filters work fine as well.
Ideally you want to pour from a temperature controlled gooseneck kettle. That allows you to precisely control your pouring speed. They don’t have to be expensive. Alternatively you can get a Hario Drip Kettle Air for pouring.
And most importantly buy good coffee.
