"Your pourover brew might taste watery if it is underextracted. This might happen if the coffee doesn’t get enough contact time with the water. Try fining up your grind, thereby extending your brew time and see if it makes a difference. You can also increase your brew ratio (ie use more coffee while keeping the water volume the same). Have a play around and discover where your preferences lie.
It’s important to remember that pourover coffee, by nature of how it’s brewed, has a much lighter body and mouthfeel to other brew methods, which can come across as watery if you aren’t use to drinking it. With a bit of practice with both brewing and drinking pourover, we’re sure you’ll come to love it!
