Some people think that store-brand products like those under Costco’s Kirkland Signature label are manufactured by the retailer themselves. But in reality, those items are made by third-party companies that are selling similar products under a set of different brand names. While a few of those brands remain undisclosed, several of them are already public knowledge. Below are some of the popular brands behind Costco’s Kirkland Signature products.
Acetum balsamic vinegar
Costco’s Kirkland Signature Aged Balsamic Vinegar of Modena proudly displays the name of its 100-year-old manufacturer on its bottle. According to the Costco Connection magazine, the retail store chain has teamed up with the Modena-based company Acetum since 1999 to make its balsamic vinegar.
