I have just bought 2nd hand Alex Duetto 2 and am using my Breville Smart Grinder and am finding that my extractions are bitter. I have tried some different grind sizes but am still finding it bitter. What am I missing?
PID twin boiler yes? Tried dropping the temp a few degrees? Find the temp where it starts to get a little sour, then go up 1 degree at a time until its to your liking.
