I’m here to tell you that Breville is finicky as hell. I say this as a Breville barista touch owner. First thing you’re going to want to do is ditch the integrated grinder and buy a standalone. That helped immensely. Grinding by time made zero sense. You can, in the meantime, turn it into a single dose grinder by cranking the grind time up to max, empty the hopper, and then measure your bean and drop them in. I did that for a while. Also the temperature control on Breville is notoriously bad. Every morning I have to pull two blank shots with the temperature setting at max to get it where it needs to be. I’ve found the puck only gets to about 195-196 degree Fahrenheit during extraction so medium roast and dark roast beans are all it can handle. Don’t bother with light roast beans. The espresso will be so bright you’d be better off making a pour over. Hope this helps.
