I love travelling Italy and tasting all of its regional amari. This winter we found a rich, spicy-bitter-sweet delicacy in Umbria near Perugia. Paxis flavored with a blend of local herbs, spices, citrus rind, and most distinctively, olive leaves.
I liked this amaro- dark, rich and full of those deeply green vegetal notes that really do recall the waxy leaves of an olive tree. This was lovely as a digestivo after dinner, and would be delicious slightly chilled, perhaps with a cube or two of ice.
