"Black darkness overwhelmed.."

In the Gaggia Classic 2018/19 with various settings on the new grinder I acquired, the Eureka Mignon Zero, I couldn't manage to enjoy a coffee (freddo espresso) yet. I have already had 4-5 coffees with the grind set to fine, resulting in an extremely dark coffee and a tremendous bitterness (20g of coffee produced 20ml, a 1:1 ratio), while at 2 or 3 coarser settings on the grinder, it produced a coffee with more crema (20g produced 50ml and 20ml of crema). It was completely indifferent, as if I was drinking hot water with dirt, with zero aroma and intensity, although surprisingly it had a full body, especially after adding ice, which it maintained for hours in the glass, which was the only positive aspect of the situation, if you will.

The worst part of it all is that I bought it from a large supermarket chain at a higher price than the one listed here on Skroutz. The coffee had been prepared (and therefore roasted) on 18/1/2023, and I opened the package and made the first coffee on 20/4/2023 (exactly 3 months later).

I would not recommend it for freddo under any circumstances, especially if you drink it plain. Spend a little more and buy from a local roaster that you like, and ask for the roasting date if it is not listed. I will simply use this one to better understand the grinder and move on to something that you can actually drink, what a shame.
