The term for coffee tasting is cupping. It's the art of comparison. If we remove some variables like the coffee ground, time brewing and the amount of water, we can evaluate the coffee and maybe even understand the coffee bean's origin.
The words experts and conoiseurs use to describe blends and coffee flavors can be wild, pretentious, descriptive and also just plain spot on.
If you tasted just 3 to 5 coffees in a row you too would sense the difference. And you too can come up with your own descriptive words. Is this coffee from Kenya, Congo or Gautemala? Can you describe the flavor, body and finish?
I prefer smooth yet dark and toasty flavors in coffee. I drink my coffee black and so I sense a lot of these subtle differences. When I occasionally add cream then caramel and deep toasty flavors are best with the cream.
I suggest buying Illy Italian whole bean coffee for the coffee lover who wants this smooth rich taste. When you buy a whole bean you can control the grind and ensure the freshest coffee taste.
