Dubbed "Operation Swill," the yearlong investigation found that establishments had filled premium brand bottles with cheaper booze in an effort to fool customers and increase their profits.
The inquiry was conducted by the Alcoholic Beverage Control Division and executed by more than 100 state investigators. The seizures announced Wednesday were done with the assistance of the state's Criminal Justice Division.
The enforcement action stems from citizen complaints, confidential informants and new technology used to test samples taken covertly from the establishments.
