So, do you feel that the unspoken answer is the location where it is grown?
That is what I am thinking, assuming a good roast and brewing. A friend sent me some on-line beans he had roasted. They were from Madagascar and various parts of Africa. You could definitely taste the difference in the flavors.
I enjoyed the flavors, but I will say that coffee is one of those things where I don’t appreciate a great deal of variety. I know what I want it to taste like in the morning, and that is what I aim for - consistency. I don’t really need a morning surprise, even a good one.
With great beans, a perfect roast and grind, the water used for brewing will make completely different cups when tap water is used, rather than filtered water.
