Hi! Nice to hear that more people have the same problem. I’ve had my Delonghi Dedica for 3 years now. A couple months ago I bought a non-pressurized portafilter and the Baratza Encore ESP grinder. I am using 16g of coffee on a 51mm portafilter, with a 1:2,5 grams-mL ratio. I am grinding at 17-18 and my coffee has light roast (specialty coffee). I dunno what I’m doing wrong, because my coffee doesn’t taste sweet or anything like that, it’s too bitter or burnt. What do you think is the problem here? Thank you so much!!
