What Company Is Behind Costco's Kirkland Brand Greek Yogurt?

Sold in three-pound tubs, the Kirkland Signature Greek yogurt is a product Costco has never outright stated the producer of. However, Ehrmann could be the company that produces it.

Ehrmann (called Commonwealth Dairy in the U.S) is originally a German dairy company founded in 1920. It completed construction on a U.S production location in Vermont in 2011.

In 2014, Ehrmann announced it was releasing a new strained Greek yogurt that would be distributed at Costco stores around San Francisco before expanding the product nationwide.

"Disciplined Growth Strategies," a 2017 book written by businessman Peter Cohanthat, also claims Ehrmann sells Greek yogurt to Costco under brand labels like Kirkland Signature.

However, Erhmann has never specified that the yogurt it supplies to Costco is labeled as Kirkland Signature, but evidence certainly points to them as a possible producer.
