I will take anyone's advice! I am so fed up of my coffee, at home, not tasting as good as the stuff I drink at Caffe Nero (nero - my hero).

I have tried: espresso machine; percolator; filter machine; plunger-type jar.

It may be the blend I use (Lavazza, at the moment). It may well be the water that comes out of the tap. I don't know. But I need some coffee-flavoured advice, please.
