Hi,

I've been using a Delonghi Dedica for years with the pressurised basket and found that it makes pretty good coffee (to my untrained taste buds).

Recently bought an unpressurised basket and handle for it, but having trouble getting good coffee out of it.

I'm grinding much, much finer that before (still using a cheap electric bur grinder). I've found this is the only way to get crema. If i go one step finer on the grinder, the coffee machine cant even pump water through the grounds.

Using about 10g of coffee and tamping hard to create pressure, but even with that little coffee I'm just getting very strong and very bitter coffee. Extraction time is about 30 secs.

If I grind coarser, there's not enough pressure and you get an acidic coffee with no crema. Adding more coffee doesn't appear to create more pressure. Tamping harder doesn't seem to make much difference.

I wonder if anyone here has mastered good coffee with this machine.

May try my hand grinder next time. Could be the grinder is too cheap.

Cheers

Forget about the crema. That mostly says something about the freshness of the roasted coffee beans.

I never had this particular machine, but there's one important rule for good espresso: you need a good grinder. It's one of the most important aspects when making espresso.

Seeing as you're using a cheap grinder, this is what you need to improve if you want to improve your espresso.

Maybe I've ground too fine then. I thought crema was an indicator of good pressure!

If budget is an issue (not everyone is able or willing to spend much money), you could look out for a decent manual grinder, those are cheaper than electric ones, but you can get a more homogenous particle distribution from your grind which helps a lot with taste and reproducible results.

I have a manual grinder and an electric one.

Both claim to be burr grinders, but who knows!

The manual one was from aliexpress...

right you will need a grinder that has a fine range of adjustment in grind size around the limit of what you are using now

Grinder and water. Reverse osmosis water is "good enough", despite what anyone else might tell you. It's cheap and works almost as good as purpose-built water 4x the price. First, as Zoldyck said, focus on the grinder. Use RO water for now, as you spend your budget on that grinder.
