I own a DeLonghi Dedica coffee machine for a year now and recently invested in a good burr grinder (Sage Dose Control Pro). I like drinking long coffees with milk and I’m satisfied with the coffee the DeLonghi machine produces.
The machine comes with pressurized filter baskets, and after doing some research online I found that non pressurized filter baskets can actually produce even better espresso. So I decided to buy a naked portafilter with a non-pressurized filter basket on AliExpress.
However, I am still struggling to get something good out of the non-pressurized one. Often it is so strong and bitter that I can’t even finish it and I can’t wrap my head around why this is happening.
How is it possible, given the same dose of ground coffee and the same grind setting, that with a pressurized filter basket I can create a coffee that’s actually pretty nice, and it doesn’t even matter how much water runs through the coffee grounds, if my tamp was level, etc., but with the non pressurized basket I can’t get anything drinkable?
