This is the only true espresso Lucaffe. Here are just high-quality Arabica beans were used. The mixture and the beans used is top secret. Man knows only the 10% Blue Mountain beans should be included from Hawaii. This espresso is not bitter and also has very low acidity. Slightly fruity, sweet and yet he has a few edges and corners. Just not a typical Lucaffe. The other varieties of Lucaffe are unfortunately inconsequential and do not begin to approach the Bluecaffe.
