Traditional tools for extraction
The " Roncola "(billhook), the " Rastrello " (a particular spoon), the Spugna (loofah sponge), the " Ramiera " (copper container) and the " Concolina " (terracotta vessel) are tools used for the extraction of the PDO-status-awarded Bergamot Essential Oil according to the manual "sponge" method, in use until the mid- 17th century . Vincenzo Amodeo , the last of the " Spiritari " (expert workmen involved in the manual extraction of bergamot oil), used this method which required 400 kilograms of Bergamot to obtain 1 kilo of oil; according to the Calabrian method, 200 kilograms are needed.
