I have got a Breville Barista Express just before a couple of days and I am trying to make the best single espresso shot I can make with this machine at home.
For the last two days I was playing and changing with the settings of the machine to reach to the signs of the good single espresso shot as described on the internet... they are saying that the pressure gauge needle has to point to 12 o'clock.... I don't know if that is correct ... anyways I have reached to that.
But on the internet, they also say that the extraction time for a single shot should be 20 seconds ... in my case it is 15 sec. .... what is wrong?!
Please know that I am using the single shot single wall basket, and a Starbucks medium roast coffee beans that was produced before 5 months.
