I love coffee. I will only drink real coffee, I don't do instant except under extreme circumstances. I only have one cup per day as a rule, but that one cup has to be good.
After many years of experimenting the coffee I buy time and again is Waitrose's Mountain Blend. I discovered that I like a fairly strong brew, but and here's the important bit mildly roasted beans - that in my opinion is the secret to a great cup of coffee.
The worst coffee I have come across was in New York - not only was it bitter and weak, it brought on dizzy spells every time I tried to drink it.
Coffee, toast with lemon marmalade - I couldn't help myself this morning.
