Made this simple blend:
2 parts: Washed Kenya Arabica AA top
1 part : Ethiopia Washed, Mocca, Yrgacheffe, Grade 2
... and wow It's delicious, and I wonder why I've never tried it before. The smell is intense, while the crema is thick almost like 'whipped cream' And best of all: the taste is crisp on the tongue and somehow refreshing (suppose this is due to the 'apple syrup' of the Kenya and the 'citrus' of the Yrg. ). I'ts almost like a good Chablis: citric/little restrained fruit,flowers and in the mouth rich full bodied (syrup like) acids which I have to balance with some sugar (not in the Chablis of course...).
Anyway, it's quite nice and I'm happy with it.
