Kirkland Signature Greek Yogurt

Kirkland Signature is the private-label powerhouse of Costco Wholesale, developed to provide members with high-quality alternatives to national brands at significantly lower price points. Launched in 1995, the brand was named after the city of Kirkland, Washington, which served as Costco's corporate headquarters at the time. The transition to a single, unified store brand was a strategic masterstroke that simplified the shopping experience and built immense consumer trust across thousands of product categories.

While Costco maintains strict quality standards, it does not typically own the manufacturing facilities. Instead, it partners with leading global and local suppliers. For the Canadian market, Kirkland Signature Greek Yogurt is prominently produced using 100% Canadian milk, often bearing the 'Blue Cow' logo from the Dairy Farmers of Canada. In the United States, industry experts often link the production of this yogurt to Ehrmann (Commonwealth Dairy), a major German-owned dairy company with large-scale production facilities in Vermont.

Today, Kirkland Signature is one of the most successful retail brands globally, generating tens of billions in annual revenue. It remains under the ultimate ownership of Costco Wholesale Corporation, which continues to manage the brand from its current headquarters in Issaquah, Washington.
