I have a breville barista express
I have been fine with extractions so far with the exception of one bag of beans that I purchased from a local roaster. The beans are very light roast (possibly cinnamon) and they are chubby (wider than long). My issue is this: pressure is high, but it’s always underextracted with very little pale crema and highly acidic taste. Increasing fineness does not help–it simply stops flowing at a certain point without solving the issue. The flow is watery and very thin no matter what I do. Any suggestions on how to proceed? All other beans I have used are great.
Thanks, I searched and didn’t find anything like this so hopefully this is not a duplicate question.
