Two Californians are suing Starbucks claiming their Grande-size lattes don't measure up to the 16 fluid ounces advertised on the coffee giant's menu.

Sierra Strumlauf and Benjamin Robles are seeking class-action status in California federal court for what they allege are underfilled lattes that have saved Starbucks "countless of millions of dollars in cost of goods sold."

According to the complaint, “Starbucks lattes are uniformly underfilled pursuant to a standardized recipe ... leaving at least (a quarter-inch) of space below the rim of the serving cup."

The lawsuit sets forth multiple counts, including fraud, breach of express warranty, and breach of implied warranty of merchantability.

“We are aware of the plaintiffs’ claims, which we fully believe to be without merit,” a Starbucks spokesperson said. “We are proud to serve our customers high-quality, handcrafted and customized beverages, and we inform customers of the likelihood of variations.”
