State officials have seized inventory and demanded records from 29 bars and restaurants from around New Jersey who allegedly sold low-quality products to patrons who thought they were buying premium brands.

Dubbed "Operation Swill," the year-long investigation was conducted by the Alcoholic Beverage Control Division. The seizures announced Wednesday were done with the assistance of the state's Criminal Justice Division.

Officials say the establishments allegedly filled premium brand bottles with non-premium brands in an effort to fool customers and increase their profits. The customer paid for the premium brand, but was instead, unbeknownst to the customer, poured the non-premium brand.

The enforcement action was executed by more than 100 state investigators. It stems from citizen complaints, confidential informants, and new technology used to test samples taken covertly from the establishments.
