Double corona
One of the longest classic formats — around 19.4 cm at ring gauge 49.
The double corona measures 19.4 cm (7⅝ inches) at ring gauge 49; in Cuban factory terminology the vitola is called Prominente. Despite the name, it is not twice the size of a corona but its elongated extension. Anyone who lights one should plan on an hour and a half to two hours — a format for an evening without obligations.
