A lawsuit filed in a Northern California federal court last week accuses Starbucks of deliberately underfilling its latte cups by 25 percent in order to save money, The Seattle Times reported.
The suit said Starbucks routinely leaves about 1/4 inch of milk foam at the top of the 16-ounce "grande" lattes, leaving space once the foam settles. It's Starbucks' own "standardized recipe," according to the lawsuit.
"Today's" Rossen Reports bought the same grande latte at six different Starbucks locations, then measured them in laboratory-grade beakers after allowing the foam to settle.
All of the cups missed the 16-ounce mark, with only two cups coming close.
Starbucks told NBC News the lawsuit and Rossen Reports' experiment are "unscientific" and "without merit."
