Hello, I'm new to coffee making and I tried to get all the information off videos and posts online but I have a question. I bought a delonghi dedica. I read and watched a lot before I want to try make a decent espresso. Don't roast me on the machine or my skills because I don't have any money for good machinery and no knowledge for espresso making. I know how to set time on the dedica and set the single shot button to 26sec. Now I want to get the grind size right but I get confused on how to do it. Everyone says that my grind size will affect the shot time but I don't understand how the shot time can be affected when the button always runs 26sec. I thought I would just adjust my grind size to the 1:2 ratio so I don't have to worry about the timing. Is this the way? Or do I need to do something else for decent espresso.
