Mirto is a Mediterranean plant producing myrtle berries flourishing in Sardinia and Corsica. Moreover it is a very popular liqueur produced from its berries and leaves.
The berries are collected between late December and January, when they are perfectly ripe. They must have a blue-violet colour, and can be eaten.
Mirto can be extracted by the infusion of myrtle leaves as well. In this case, the leaves are collected during spring time, and the result is a white liqueur, the so called mirto bianco.
