First time poster. I use a Kalita wave, baratza vituoso, 15g coffee and usually 255ml water.
My issue is this: I got a bag of Ethiopia (yirgacheffe) with a subscription this month. I’ve had a hell of a time trying to get a drinkable cup out of it. If I grind it as fine as I want to for extraction purposes, it will clog the filter and the drawdown time goes through the roof; the last 25ml alone takes a good 2-3 minutes to pass through the bed of grounds, and the cup ends up powdery and gross. If I open up the grind, the coffee ends up sour and equally undrinkable.
This isn’t the first time I’ve experienced this problem, where the filter seems to clog before the coffee can fully extract. Very frustrating! Can anyone offer some advice?
