Really though it's a house by house, and often fragrance by fragrance assessment that's required. Generalising based on the country of origin won't get you far.
I think it is possible to guess what house a fragrance is from. There are some fragrances that can be identified as one of a kind. Anyone who smelled Aventus should be able to tell it from other scents. Same logic for AdG, TF scents, HM, Hermes, A*Men, ect.
This is like guessing what company makes a suit without looking at the label. I think it is possible to tell Brioni from Armani from Boss from RL just by looking at the design, feeling the wool, looking at lapels, looking at pockets, ect. Each house has their designers, and its possible to identify the creator of a product with enough familiarity. Creators tend to use the same style repeatedly across different products.
