La Vieja Fábrica blueberry jam

La Vieja Fábrica is a renowned Spanish brand specializing in fruit preserves, marmalades, and fruit-based spreads. The brand traces its origins back to 1834 in Seville, Spain, where its unique slow-cooking process was first developed to preserve the texture and flavor of whole fruit. This heritage of traditional craftsmanship is reflected in the brand name, which translates to "The Old Factory."

The product is primarily manufactured in Spain, specifically at the facilities of Gruppo Hero (Hero España) located in Alcantarilla, Murcia. The brand was acquired by the Swiss-based Hero Group in 1982, which integrated it into its international portfolio while maintaining the distinct Spanish production methods and quality standards. Today, it remains a staple in Spanish households and is exported globally as a premium preserve brand under the stewardship of the Hero Group.
