Kirkland Signature Organic Fortified Soy Beverage

Kirkland Signature Organic Fortified Soy Beverage is a prominent plant-based dairy alternative sold through Costco Wholesale. The brand, Kirkland Signature, was established in 1995 as the exclusive private label for Costco, named after the city in Washington where the company's headquarters were originally located.

While the brand is American, this specific product variant is manufactured in Canada using both domestic and imported ingredients, as indicated by the maple leaf logo on the packaging. This allows the brand to maintain local distribution efficiencies for the Canadian market while adhering to the brand's global quality standards.

As of 2026 and beyond, the brand remains under the ultimate ownership of Costco Wholesale Corporation. Costco operates as a multi-billion dollar global retailer, utilizing a membership warehouse club model. They often partner with major third-party manufacturers to produce high-quality products under the Kirkland Signature label, which are then sold at lower price points than national brand counterparts.
