The Strength of Tunisian Terroir

Tunisia’s olive oil is shaped by a dry Mediterranean climate and traditional farming practices. Olive trees are widely spaced and dry-farmed, relying primarily on natural rainfall, which promotes deep root systems and resilient trees adapted to their environment.

These conditions result in olive oils with natural balance, stability, and concentration. Abundant sunlight and mineral-rich soils contribute to distinctive flavor profiles and consistent quality, defining the specificity of Tunisian olive oil.

Production Process

Harvesting

Hand-picked with care and respect for the land, our sustainable harvesting methods protect tree health while ensuring that only the fresh olives are selected.

Transport

Freshly harvested olives are delivered to our mills the same day, never exceeding six hours from grove to press.

Extraction

Cold-pressed using advanced technology that extracts oil without heat or chemicals.

Storage

Our oils are filtered and stored in temperature-controlled stainless steel tanks, preserving their taste and antioxidant properties until bottling.
