Why are Espresso Blends so Complex?

The complexity of an espresso blend is something very important for the roaster. It is part of his “savoir faire” and his own knowledge. By coffee roasters, the recipe is the identity of the brand and therefore all recipes are well protected against hard copy. As recipes can’t be protected by IP, a way to do it is to complexify the blends, but does it make sense to complexify espresso blends in organoleptic point of view? I have some doubts, but it

      What is the point of creating a blend of espresso with 5 to 10 different coffees? I don’t know how this would make the espresso more amazing? When I am looking to blend and roast coffee i am trying to bring things to the palate , fragrance and visual ecstatic. I just don’t think you need 5 to 10 different coffees to achieve creating an amazing espresso. This is just my own personal opinion.

      We are making blends with no more than 3 differents green coffees and using differents rosting points to highlight/hide some flavors, I think if we use more the 3 green coffees we lose all the special features of each coffee.

      You are forgetting something. If you blend before roasting, during roasting a chemical process starts. Flavor, smell and taste are blending. Compare it with Bolognese sauce…. If you cook your tomatoes, your meat, unions etc… separately and you put them together, it doesn’t taste like Bolognese, but if you cook it together it is Bolognese.
      The same with coffee! Your blend tastes different comparing to your singles. And than its not is big difference in taste when you have to change 1 single or more. So make the calculation again if you change 1 of the 5 and 1 of the 9 singles. what is your taste difference.?

      I do not agree or disagree 4-5-or 9 different green coffees, my blends are 4, 3 or 2.
