Introduction

Global demand for Mediterranean olives continues to grow across retail, foodservice, and private label segments. For importers, wholesalers (Oliven Großhandel), and Lebensmittelimporteur partners, selecting the right olive variety is not only about taste — it is about consistency, sizing accuracy, processing method, EU compliance, and full traceability (Rückverfolgbarkeit).

This guide provides a structured overview of black and green olive varieties in international trade, including specifications relevant to European markets and global buyers.

1. What Is the Difference Between Green and Black Olives in Export Trade?

The primary difference is harvest stage, which directly affects texture, flavor, and processing method.

Green Olives

• Harvested before full ripeness

• Firmer texture

• Mild to tangy flavor

• Often lye-treated or naturally fermented

• Popular in retail jars and private label programs

Black Olives

• Harvested at full ripeness OR oxidized during processing

• Softer texture

• Richer or milder flavor (depending on method)

• Common in sliced, pitted, and foodservice formats

In international trade, the distinction is also commercial:
Green olives dominate premium table olive (Tafeloliven) segments, while black olives are widely used in foodservice and industrial applications.

3. Standard Olive Sizes in Export (Caliber Classification)

Size consistency is a critical purchasing factor.
