Bergamot Essential Oil. The oil of the bergamot fruit is historically one of the first ingredients of perfumery. A scent that enhances all other scents, like salt in cooking - it encompasses a wide spectrum of aromas within one simple fruit -  citrus, floral, mineral, woody. The traditional method of extraction is to cut the fruit in half, and scoop out the flesh with a special spoon, and then, with a natural sea sponge, repeatedly rub the skin of the fruit, so the oils transfer into the sponge, and then the sponge is squeezed into a terracotta pot.
