Sicilian Extra Virgin Olive Oil cold pressed from olives organically grown, hand picked, and harvested last season. This olive oil has a unique taste because it comes from an area with special red soil. If any residue at the bottom of the bottle is because of the very little filtering processes. the price is for a 50ml glass bottle, infused with organically grown rosemary. The glass bottle has been cleaned and rinsed with boiling water and dried before pouring oil. These can be taken as well with your liquids on the plane. Thanks
