Pennsylvania wine lovers can now purchase a bottle at supermarkets -- but only after they blow into a Breathalyzer.

Easing up on its strict liquor laws, the Pennsylvania Liquor Control Board this week began allowing wine sales in grocery stores. The pilot program involved machines installed in two stores near Harrisburg.

After selecting which wine they want on a touch screen -- the machines offer 53 varieties -- wine drinkers insert their drive's license (an employee at the Liquor Control Board can see the customer through a camera) and their credit card into the device. Then they are asked to blow into an opening in the device.

Only those who are sober get the sale.

If successful, the PLCB aims to launch kiosk sales in at least 100 stores statewide in August.
