Our Story
“Taste the tradition, experience the purity. Join us in celebrating the finest olive oil crafted with passion.”
It all began in 1980 with Gaddour, a visionary farmer in Jemmel, Tunisia. He built the town’s first modern olive mill to help local farmers process their olives more efficiently, reduce losses, and enhance quality. Years later, his daughter and her husband took this vision further by pioneering the export of premium, single-origin Tunisian olive oil, a revolutionary step at the time. With a deep commitment to quality olive oil, they embraced sustainable and organic farming practices, introducing innovative methods such as stainless steel storage tanks and fresh olive transportation in bins. These advancements set new standards in traditional olive oil production and paved the way for international recognition. Today, GREATLINES continues this legacy as a family-owned olive oil producer, blending artisanal craftsmanship with modern techniques to deliver the finest Mediterranean olive oil to the world.

Commitments
At GREATLINES, we are dedicated to sustainable olive farming, quality preservation, and ethical production. From handpicking olives at peak ripeness to using eco-friendly processing methods, we ensure every drop of our oil meets the highest standards.
HARVESTING
Harvest time starts mid-November and lasts no longer than 3 weeks. The Olives picked by hand fall onto nets placed under the trees where they are gathered, cleaned of all leaves and taken to the press. Here, olives undergo further defoliation and are washed and crushed before the end of the day, no longer than 6 hours after picking. We use continuous centrifugation using a two phase-system at a temperature not exceeding 27°C/80°F degrees, according to EU regulations for cold extraction
TRANSPORT
After the batches of olives are traditionally hand-picked we immediately transport them to the mills within the shortest time possible and it never take us longer than six hours. We control all aspects of the production process from the harvest to bottling in the knowledge that this is the only way to guarantee our consumer the ultimate in quality.
EXTRACTION
Once cleaned, the olives are then put through cold-pressing using the latest technology and the most attentive care to preserve the full complex range of sensory and nutritional qualities; allowing the complete flavor of the olive oil to be appreciated. In this method, no heat or chemicals are administered to extend or alter the oil.
