Mercadona Soy Sauce

This product is a soy sauce marketed under the private label of the Spanish supermarket chain Mercadona. Although it is a staple of Mercadona's Hacendado brand line in Spain, the labeling explicitly identifies the manufacturer as Mautner Markhof Feinkost GmbH. This manufacturing partner is a long-standing Austrian company based in Vienna, specializing in vinegars, mustards, and fine sauces.

Mercadona, the ultimate owner of the brand's retail presence, is one of Spain's largest physical and online supermarket retailers. The company frequently collaborates with international specialized manufacturers like Mautner Markhof to produce its private-label goods, ensuring European production standards while maintaining competitive pricing for the Spanish and Portuguese markets.
