Home delivery of alcohol in Prince George’s County — which also has several drive-through liquor stores — has been going on for years, according to the county liquor board, despite a flurry of stories Tuesday about a measure to allow delivery.

According to a liquor board spokeswoman, a new gourmet store in National Harbor inquired about deliveries and submitted a proposal to formalize what has been a somewhat informal system.

But the proposed regulation may not sit well with liquor stores that already deliver, because it could cost them $250 to apply to do something they already do. The measure also would require deliverers to have alcohol awareness training, deliver during normal liquor store business hours and ensure that the customer is at least 21 years old.

The liquor board will take up the proposal June 28.
