“Filo d'olio” has been designed by Marta Sansoni. It is a little iconic mechanical gem for use with “green gold”, another name for olive oil. It is a cap with a pouring spout that fits into the neck of the bottle, allowing us to pour only as much as we need on our food while controlling the oxidation process that begins as soon as the bottle is opened. The small glass container that houses it has a second function: To assist professional tasters to sample the oil according to the time-honored tradition.
