Chile standardises table grape sizes for export markets

Chile’s table grape sector is moving to standardise export size classifications, with the Frutas de Chile Grape Committee introducing a calibre homologation framework covering multiple varieties.

Presented by committee executive director Ignacio Caballero, the document aims to align how fruit dimensions are defined according to varietal genetics and colour, creating a unified technical reference for export markets.

Chile currently exports more than 63 table grape varieties, operating across 46 calibre ranges and five different nomenclature systems, from S–XL to A–J scales, with additional breeder-specific classifications. The lack of alignment has complicated commercial communication and specification matching overseas.

The homologation establishes millimetre-based ranges spanning categories from M to JJJ under two main standards.

The first, applicable to more than 40 varieties, defines XL fruit at 20–22 mm, while JJJ covers grapes exceeding 26 mm.

A second standard, designed for 10 specific varieties, sets XL at 19–21 mm and JJJ above 25 mm.

The framework also includes a “Special” classification for varieties with distinct morphological sizing requirements.

The system is intended to harmonise technical language across the industry, improving consistency in export specifications and buyer communication.
