PITTSBURGH — The Pennsylvania Liquor Control Board is seeking proposals for a contractor to operate up to 100 wine kiosks throughout the state.

The kiosks, a sort of a temperature-controlled vending machine capable of holding 500 bottles of wine, would be placed in grocery stores and other places, according to request on the LCB's Web site. They would offer about a dozen different types of wine.

Wendell Young IV, president of the United Food and Commercial Workers Local 1776, whose members include state store clerks, was among those briefed on the proposal. The kiosk has security identification measures such as fingerprints and biometric readings, he said. Users would have to register and purchases would have to be made with credit card, debit card or PLCB gift card.
