Good day,
I have a DeLonghi Stilosa & a Breville Smart grinder pro, I'm new to grinding my own beans and can't figure out what the grind time or grind size should be. The inner burr I believe is set to 3, I se lt the machine to grind size of 12 for 25 grind time, grid size 15 with 17 grind size & I'm having no luck. First time I got beans it was ground for me at Whole Foods & it was perfect. But as they say freshly ground beans are best but I need some advice to figure out what is a good starting point. The portafilter on the DeLonghi is pressurized as I just learned.
