The "juice" is the great description developed in a five part series published on italyMONDO!'s site, with the collaboration of Ciao!Amalfi. This should appease any curiosity which ensued from my post on the olive harvest I participated in at the farm Monte Sereo in November. For a quick read of that post for those who missed it, here is the link.
Reminder: make sure you have some good quality olive oil on at least one dish during your this holiday season and think of Italy!
