The Essence of the Olive: Single Source Tunisian Olive Oil from Terra Delyssa

Our history goes back to many generations cultivating olive trees and producing olive oil. In the 1990s, CHO Company began selling its olive oil in bulk to co-packers and manufacturers in Europe. Dismayed to see our beautiful, golden, smooth tasting olive oil blended with lesser quality oils from other countries, we developed Terra Delyssa to be the ambassador brand of Tunisian olive oil. -- Terra Delyssa

Farmers in Tunisia have cultivated olives for thousands of years, with archaeological evidence showing organized production during the Phoenician and Roman eras. Today it remains one of the world’s largest olive‑growing regions, and the Chemlali cultivar dominates central and southern Tunisia, where semi‑arid conditions, sandy loam soils, and limited rainfall favor its growth. Chemlali is well adapted to these environments, producing small, dark fruits and resilient to drought, poor soils, and temperature extremes. 

Terra Delyssa is named after Queen Elyssa, (Dido in Virgil's Aeneid) - the legendary Phoenician princess from Tyre who fled her homeland to found the city of Carthage in modern-day Tunisia around 814 BC.  They are also the sister brand to Moresh - the Moroccan brand we recently featured.  Terra Delyssa sources Chemlali olives from certified organic estates, relying on the stable climate and traditional agricultural practices to maintain uniform quality across each harvest. Olives are generally picked between November and January and milled within hours to preserve freshness. 

The company’s Single Source bottling emphasizes traceability: each bottle includes a QR code linking to harvest location, milling and bottling dates, and laboratory analysis using  IBM’s blockchain technology. These analyses routinely include phenolic measurements, and the Single Source Smooth olive oil typically falls within a moderate phenolic range appropriate for a mild Chemlali profile. Recent batches have shown total phenolic content around 200–300 mg/kg, reflecting the cultivar’s naturally soft character while still meeting recognized thresholds for freshness and stability. Terra Delyssa publishes these results alongside pesticide‑residue testing showing non‑detectable levels, reinforcing its organic and zero‑residue positioning. The bottle also displays multiple certifications documenting compliance with international quality and safety standards, including USDA Organic, Non‑GMO Project Verified, Kosher certification, ISO 22000 and ISO 9001 management systems, and SQF Level 3. 

The resulting oil reflects the Chemlali cultivar’s typical sensory attributes: mild and fruity, typically showing notes of green apple, almond, and herbs, with low bitterness and a gentle, delayed pepper finish. This makes the Single Source Smooth suitable for salads, drizzling, baking, and other applications where a mild extra virgin olive oil is preferred.
